ChangeLog.2007

2007-08-23  Al Stone <ahs3@debian.org>

	* debian/: removed.  Debian packaging will be kept separately.
	* src/linux/syscall-linux.c: from Peter Chubb -- on AMD64, pointers
	are 64-bits, and ints are 32-bit.  This means that variadic functions
	like execlp() must specify the NULL at the end of the list of arguments
	as NULL not zero.  Without this, the rest of the 64-bit pointer is
	garbage, and can result in segfaults.  Fixed execlp() usage in
	initConsole().
	* src/: from Ian Wienand -- various changes and additions to
	get a GTK interface working.
	* src/linux/syscall-linux.c: from David Mosberger -- repair problem
	with user-level simulation and newer glibc's so ski will run code
	again.

2007-08-12  Al Stone <ahs3@debian.org>

	* Incorporated several changes from Peter Chubb that allow the
	package to compile properly.
	* src/memory.c: trivial patch to silence output about unaligned 
	copies (David Mosberger)
	* release 1.1.3-gplv2 to SourceForge

2007-08-10  Ian Wienand  <ianw@gelato.unsw.edu.au>

	* Makefile.am: remove testsuite for now, add misc/*
	* testsuite/Makefile: fix for make dist anyway
	* macros/Makefile.am: remove reference to libtool.m4
	* libltdl/*: regenerate with up-to-date tools
	* aclocal.m4: remove (autogenerated)
	* docs/ski.man: move to ski.1
	* docs/ski-manual-v1.0.pdf: uudecode
	* docs/Makefile.am: add above manual to dist, install man page in 1
	
2007-04-19  Al Stone <ahs3@fc.hp.com>

	* many files: cleaned up source in order to open up the code.
	* many files: stopped building nasty old X11 bits that didn't work,
	leaving ncurses interface only.  Dependency on Motif was no longer
	tenable.  All the code is still there, just disabled.
	* many files: incorporated all known patches (about 99.9% of which
	are from Dan Magenheimer).
	* configure.ac: set default PAGER to less, as it is the only one
	that seems to work properly with Ski.

2004-11-15  David Mosberger  <davidm@hpl.hp.com>

        Based on patch Konstantin Belochapka:
	* src/linux/syscall-linux.c (slave): Change to char *.
	(SLAVE_ID): Delete.
	(getPty): Use getpt()/grantpt()/unlockpt() API instead of open
	code.
	(initConsole): Pass last two characters of slave tty-name to
	xterm.  This may be wrong, but xterm doesn't seem to care about
	the pty-name much.  The important part is the file-descriptor
	number and that we get right.

2004-05-07  David Mosberger  <davidm@hpl.hp.com>

        * src/ui.c (regwtbl): Change height of System Registers info from
        43 to 64 lines.  (srLine): Adapt to make room for 64 PMC and PMD
	registers (man, this code is in need of a rewrite!!).

        * src/ssDSym.c: Add include of "state.h" so we get NPMS defined.
        (isymInit): For PMCs/PMDs, call isymIns2() with -NPMS instead of
	-16.

        * src/libcore.h (NPMS): Increase from 16 to 64 so we get 64 PMCs
	and PMDs (like on Montecito).

	* src/state.h (NPMS): Likewise.

2004-05-07  David Mosberger  <davidm@hpl.hp.com>

        * src/state.c: Change family from 7 (Merced) to 0x1f
        (McKinley/Madison).

2004-05-07  David Mosberger  <davidm@hpl.hp.com>

        * src/write.c (cfmWrt): Restore the original value of "sof" before
	calling rse_new_frame().  That call may longjmp() if a data-debug
        breakpoint is hit and when that happens, the simulator state must
	be consistent.  Once rse_new_frame() returns successfully,
        re-establish the new "sof" value.

2004-01-22  David Mosberger  <davidm@hpl.hp.com>

	* src/tlb.h (DBGREGS): Define to enable debug registers support.

	* src/ssDSym.c (isymInit): Define ar.csd as an ia64 register
	instead of an ia32 register.

	* src/main.c (main): Allow environment variable SKI_PAGE_SIZE to
	override simulated page-size.  This is a bit of a kludge to work
	around the data-breakpoint limit, which are limited to covering
	a single (simulated) page.

	* configure.ac: Check for XtRealloc instead of XtMalloc.
	(CFLAGS): Compiled with -fno-strict-aliasing to avoid
	potential bad code (Ski isn't strict-aliasing safe).

2003-12-10  David Mosberger  <davidm@hpl.hp.com>

	* src/ssDBT.c (struct dbpt): Add members "loaded" and "padr".
	(ibptLoad): Make it return the number of to-be-loaded breakpoints.
	(dbptDisplay): Re-enable to print P for physical, V for virtual
	data-breakpoints.
	(dbptSet): Don't allow data-breakpoints to cross a page-boundary.
	Set "realmode" based on PSR.dt and clear "loaded" member.  If
	anything goes wrong once breakpoint is allocated, branch to "fail"
	label and clear the "inuse" flag.
	(dbptDelete): In addition to "inuse" flag, also clear
	dbpts[b].loaded flag.

	* src/tlb.h (dbptLookup): Declare.

	* src/tlb.c (dbptLookup): New function.

2003-12-08  David Mosberger  <davidm@hpl.hp.com>

	* src/ssDBT.c (ibptLoad): Avoid infinite recursion that could
	occur when ibptLoad() got invoked via tlbInsert() and the
	memMIRd() call caused a TLB translation to be inserted from the
	VHPT, which would then cause the recursive call to tlbInsert().
	The solution is to clear numBptsToLoad at the beginning and then
	to count the number of failed memMIRd()s in a local variable,
	which get stored to the global numBptsToLoad only at the end.
	Besides avoiding infinite recursion, this also should correct the
	counting of the number of pending breakpoints.

	* src/ssDDM.c (get_dyn_info_list_addr): Update call to
        _Uia64_find_dyn_list() to match API change introduced
	by libunwind v0.95.

2003-07-08  David Mosberger  <davidm@hpl.hp.com>

	* src/ssDDM.c (rbs_overflow_area): New variable.
	(wrap): New function (copied from exec_hd.c).
	(unwind_flush): New function.  Flushes dirty partition
	to rbs_overflow_area without affecting visible machine state.
	(access_mem): Access memory in range [ar.bspstore, ar.bsp)
	via rbs_overflow_area.
	(cstkDisplay): Call unwind_flush() instead of unwindFlush().
	The latter fails if ar.bspstore is invalid and also needlessly
	changes the visibile machine state.

2003-07-08  David Mosberger  <davidm@hpl.hp.com>

	* src/ssDDM.c (get_unwind_table): Ensure that the unwind table
	info spans _all_ text segments.  With the Linux kernel, the
	unwind table covers both .text and .text.init, so this is
	important.  Also, fix two minor debug printing issues.

	* src/linux/syscall-linux.c (_FILE_OFFSET_BITS): Define as 64
	to ensure that file system calls use 64-bit file offsets.  This
	makes it possible to run ski on 32-bit platforms with simulated
	disks that are bigger than 2 GBytes.
	(_LARGEFILE_SOURCE): Ditto.

2002-11-19  David Mosberger  <davidm@hpl.hp.com>

       * src/load.c (elf64_symbols): If symbol with same name and value
       exists already, don't reinsert it again.  Also, do not ignore
       symbols of type STT_COMMON and STT_NOTYPE.  The latter case is
       common because all code labels on ia64 linux have this type
       (STT_NOFUNC is not correct here, because STT_NOFUNC has special
       significance, according to the ELF System V ABI).

2003-03-03  David Mosberger  <davidm@hpl.hp.com>

	* src/ui.c (scrnInit): Print an error message when X_INTERFACE is
	selected but Motif is not available.

	* configure.ac: When Xm.h exists, autoconf for -lpthread, -lXt,
	and -lXp, since -lXm may need those.

2003-02-27  Laurent Morichetti  <laurentm@cup.hp.com>

	* src/tlb.c: added dtcs_head and itcs_head for the head
	of the translation cache linked list. when inserting a new
	entry in the translation cache evict the LRU entry instead
	of the oldest one.
	(searchDTLB) added 2 level cache for fast lookup
	(searchITLB) ditto.

	* src/tlb.h: added next field to struct TlbEntry, making
	TlbEntry a linklist element.

	* src/sys_exec.c: (rfiEx) should return ST_CHECK if
	cfle is set.

	* src/state.c: getIcp now returns an INSTINFO*.

	* src/sim.h: shrunk the size of INSTINFO by removing
	redundant/unnecessary fields. added a new status bit (ST_CHECK)
	to break the simulator loop. got rid of IC struct.

	* src/sim.c: complete rewrite of iCycleSysLoop. removed NEXT2
	and ADD_CTRS code. lastInstComb is not required anymore.

	* src/read.c: changes to pgrr2,pgrr3,pgrtgt. ct replaces ic.
	(callRd) use IPTR instead of retIP
	(calliRd) ditto.
	
	* src/predecode.awk: pgrtgt is now a BYTE containing the
	register number + 1 (0 means statictgt is false). Same
	for pgrr2 & pgrr3.

	* src/opcode.awk: removed lastInstCombFP.

	* src/libtrace.h: renamed qpred as it conflics with 
	the extrainfo qpred.

	* src/instinfo.h: qp is now extrainfo[0]. shifted all
	other extrainfo fields by one. removed statictgt & retIP
	as they are not used anymore. tag13 is now a word starting
	at &extrainfo[4].

	* src/fp_exec.c: ct replaces ic in INSTINFO. 

	* src/exec.c:
	(brReEx) add ST_CHECK to status if cfle.
	(breakEx) propagate ST_CHECK from doSSC to status.

	* src/combfns.awk: Added new Status st variable to allow
	comb functions to modify their return status.

2003-02-25  David Mosberger-Tang  <davidm@hpl.hp.com>

	* src/linux/syscall-linux.c (struct lia64_stat): Change member
	prefix from "st_" to "St_".  The former is reserved name-space for
	<sys/stat.h> and stuff like st_atime may actually be a macro.
	(struct lia64_old_stat): Ditto.

	src/ssDDM.c: Also pass global-pointer to _Uia64_find_dyn_list.

2003-02-20  Laurent Morichetti  <laurentm@cup.hp.com>

	* src/memory.c (Repository): PmemHash optimization to use >> and &
	instead of / and % (fix for performance regression). Inline if
	possible static pmem_* funcs.

	* src/main.c (Repository): Assert if page_size is not a power of 2
	and compute log2_page_size.

	* src/libcore.h (Repository): Added extern log2_page_size.

	* configure.ac (Repository): Added tests for inline & const keywords.

2003-02-19  David Mosberger  <davidm@hpl.hp.com>

	* configure.ac: Add AC_DEFINE_UNQUOTED for SKI_RELEASE.

	* Makefile.am (.PHONY): Mention pubdist.
	(pubdist): New target to create public binary-only release of ski.

	* src/version.c: Append SKI_RELEASE to version number if it's
	defined.

	* src/Makefile.am (ski_LDFLAGS): Use -all-static instead of
	-static (libtool seems to need that for producing static
	programs).

	* doc/ski.man: New file.  This is mostly what Stephane wrote
	for the original Ski RPM, updated with the -forcesystem
	option.

2003-02-19  David Mosberger  <davidm@hpl.hp.com>

	* src/Makefile.am (libskiui_la_LIBADD): Move $(DWARF_LIBS) to...
	(libski_la_LIBADD): ...here.

2003-02-14  David Mosberger  <davidm@hpl.hp.com>

	* src/linux/osload-linux.c (os_elf64_abi): Use force_system and
	force_user to influence "userland" choice.

	* src/linux/dwarf-linux.c (find_in_section): Initialize last_line
	to avoid spurious compiler warning.  Ditto for line_len.  Replace
	test against "true" and "false" (BFD no longer defines these).

	* src/version.c (VERSION): Remove duplicate macro.

	* src/ui.c (productInfo): Print slightly different info
	for public version (!HP_INTERNAL).

	* src/ssDDM.c: Include "config.h".
	(HAVE_UNWIND_SUPPORT): Define if HAVE_LIBUNWIND_IA64 is defined.
	Rename HAVE_LIBUNWIND to HAVE_LIBUNWIND_IA64.
	(acquire_unwind_info): Remove.
	(get_unwind_table): New function.
	(get_unwind_info): Ditto.
	(put_unwind_info): Ditto.

	(access_mem): Adjust for updated libunwind API.
	(access_reg): Ditto.
	(access_fpreg): Ditto.
	(cstkDisplay): Ditto.

	* src/main.c: Declare "force_system".
	(argsInit): Handle "-forcesystem".

	* src/load.c (force_system): New variable.
	(elfSymLoad): Initialize unwind_base to zero to avoid spurious
	compiler warning.  Remove debug printf().
	(elfLoad): When encountering PT_INTERP, check "abi", not
	unixABI.

	* configure.ac: Check for libunwind-ia64 via AC_CHECK_LIB.
	Look for -lbfd and -liberty instead of -lbfd-ia64 and
	-liberty-ia64.

2002-12-11  Laurent Morichetti  <laurentm@cup.hp.com>
	
	* (Repository): Moved os specific files to subdirectories.

	* src/exportui.h (Repository): Moved command line options functions.

	* src/ski.c (Repository): Moved command line options functions.

	* src/memory.c (Repository): segfaults if we try to map page 0.

	* src/sim.c (Repository): instDecode should return NO if the specified
	the given address is invalid and YES if it succeeds. During state
	reset, also invalidates the instruction cache tags.

	* src/std.h (Repository): Added endianness warning.

	* src/state.c (Repository): Added frSet & frGet.

	* src/libcore.h (Repository): Added frSet & frGet.

	background color to gray.

2002-05-24  Laurent Morichetti  <laurentm@cup.hp.com>

	* src/decoder/instID.awk (Repository): Do not use 'short enum' when
	using ICC.

	* src/bits.h (Repository): Only use bad_bitfx.. when compiling
	with GNUC. (ICC gets unsats).

	* src/make_asm (Repository): const on return type is meaningless.

	* src/asm.h (Repository): const on return type is meaningless.

	* configure.ac (Repository): Do not build shared library by default.
	To enable shared library add --enable-shared to the configure flags.

	* ski.spec.in (Repository): Added --enable-shared to build the shared
	library.

	* src/memory.c (Repository): Added inlined assembly for LDCWS for gcc.

	* src/load.c (Repository): lp64 and unixABI should not be static
	as they are declared extern in the headers.

	* src/eparse.y (Repository): Changed the type of str to char* to
	incompatible type assignment warnings.

	* src/bits.h (Repository): On HPUX, HP cc warns about shifts
	exeeding 31 bits (for vars <= int in size). BitfX8, BitfX16,
	BitfX32 and BitfX64 should now be used instead of the generic BitfX.
	To limitate the number of changes in the code BitfX will map
	to BitfX64.

	* macros/Makefile.am (Repository): Added compilers.m4.

	* macros/compilers.m4 (Repository): Support to automatically detect
	HP cc and Intel icc compilers. We can now set compiler specific
	CFLAGS by testing the value of HPCC or ICC against "yes".

	* ski.spec.in (Repository): Ifdefs linux specific commands.

	* Makefile.am (Repository): cleandist should remove XSki. Do not
	move the generated rpms as we do not know for sure the name of
	the build architecture (e.g. for hppa2.0w build arch name is hppa1.1)

	* src/decoder/instID.awk (Repository): The type short should be
	omitted for gcc (not just linux).

	* src/syscall.c (Repository): Changed generic BitfX macro to the one
	specialized on the type. Fixed some pointer to int conversion
	warnings.

	* src/decoder/_decoder.h (Repository): The size of InstID should be
	16 bit to match exactly with unsigned short opIndex.

	* src/load.c (Repository):  HPUX build fixes.

	* src/cur.c (Repository):  HPUX build fixes.

	* src/dwarf-linux.c (Repository): getSrcLines when bfd is not
	available should always set *count to 0.

	* src/make_asm (Repository): Added a test for gperf.

	* src/bits.h (Repository): Now that we are using BitfX for most
	field operations, the macro that tests the size of the data is
	required.

	* configure.ac (Repository): Bug fixes and added AC_PROG_LN_S,
	AC_FUNC_ALLOCA and AC_CHECK_PROG for gperf (required to build ski).

2002-05-22  Laurent Morichetti  <laurentm@cup.hp.com>

	* all: Merged with ski v0.977. Added autoconf/automake/libtool.

2002-02-27  David Mosberger  <davidm@hpl.hp.com>

	* syscall-linux.c (doSyscall.getresgid): Copy host gids to lia64
	gids before copying them to user-space.
	(doSyscall.getresuid): Ditto for uids.

	* ssDDM.c [HAVE_LIBUNWIND]: Move from here...
	* GNUmakefile (CPPFLAGS): ...to here.

	* load.c (mmapSyms): Also register symbols found in dynamic symbol
	table sections.

2002-02-26  David Mosberger  <davidm@hpl.hp.com>

	* syscall-linux.c (offsetof): New macro.
	(dirent_name_off): Ditto.
	(dirent64_name_off): Ditto.
	(getdents): Replace _syscall3() macro with a call to syscall().
	(getdents64): Ditto.
	(doSyscall.getdents): Instead of hardcoding dirent-size difference,
	calculate it as 18 (IA-64 Linux size) minus the host-size.
	(doSyscall.getdents64): Ditto.

	* version.c (VERSION): Increase version number to 0.943l2.

	* load.c (mmapSyms): Call addLM().
	(interp): Ditto.
	(elfSymLoad): Ditto.
	(elfLoad): Ditto.

	* ssDDM.c [__linux__]: Define HAVE_LIBUNWIND.
	[HAVE_LIBUNWIND]: Include <libunwind.h>.
	(struct load_module): New type to track loaded modules.
	(addLM): New function for libunwind support.
	(acquire_unwind_info): Ditto.
	(ia64_rse_slot_num): Ditto.
	(ia64_rse_num_regs): Ditto.
	(access_mem): Ditto.
	(access_reg): Ditto.
	(access_fpreg): Ditto.
	(cstkDisplay): Ditto.

	* main.c (main): Initialize page_size and page_mask.

	* load.c (segload): Round length according to host's page size.

	of dummy memMRd1().
	(doSyscall): Ditto.

	* memory.h: (memIsMapped): Declare.
	* memory.c (memIsMapped): New function.

2001-03-08  David Mosberger  <davidm@hpl.hp.com>

	* Released version 0.943l0.

	* syscall-linux.c (doSyscall): Handle SHM_LOCK and SHM_UNLOCK
	commands for LIA64_shmctl.
	(doSyscall): Handle GETALL, SETALL, GETVAL, GETPID, GETNCNT, and
	SETVAL commands for LIA64_semctl.

2001-03-07  David Mosberger  <davidm@hpl.hp.com>

	* syscall-linux.c (doSyscall): Unmap any old mappings for mmap()
	with the MAP_FIXED flag set.
	(doSyscall): For LIA64_mmap, preserve file pointer around call to
	mmapSyms().

2001-02-17  David Mosberger  <davidm@hpl.hp.com>

	* ssDBT.c (ibptLoad): Use itlbMLookup() instead of itlbLookup().
	This fixes a bug where Ski failed to remove some instruction
	breakpoints upon hitting that breakpoint.

2001-02-16  David Mosberger  <davidm@hpl.hp.com>

	* XSki.Linux: Rename <Configure> to <ConfigureNotify>.  With this,
	it's possible to resize the height of the various windows.
	Add "defaultVirtualBindings".  This FINALLY gets "Page Down" etc.
	to work in the various windows.

2001-02-15  root  <davidm@hpl.hp.com>

	* syscall-linux.c (doSyscall): When execve()ing an IA-64 program,
	do so via bskinc instead of "bski -noconsole".

2001-02-14  David Mosberger  <davidm@hpl.hp.com>

	* main.c (main): Check for program name "bskinc" and, if so,
	turn on force_user and noConsole.  We used to do this via
	a script, but that doesn't work because it doesn't preserve
	the argv vector (e.g., try "make menuconfig").

	* syscall-linux.c (doSyscall): Do proper emulation of getdents64()
	by falling back on stat().  Slow, but better to be slow and
	accurate than fast and wrong.
	(doSyscall): Make sysctl() fail silently.

	* load.c (elfLoad): Also allow ET_DYN as an executable file
	(under Linux at least, /lib/ld-linux-ia64.so.2 is executable and
	used by ldd).

	* dwarf-linux.c (load_symbols): Don't fatal_error() if file
	doesn't have symbols.

	* syscall-linux.c (doSyscall): Fake v2.4.0 for uname().  glibc-2.2
	otherwise refuses to work (see
	sysdeps/unix/sysv/linux/dl-osinfo.h).

	* load.c (LINUX_ULD_TADDR): New macro.
	(interp): Set uld_taddr to LINUX_ULD_TADDR if linuxABI is in
	effect.

	* syscall-linux.c (doSyscall): Replace LIA64_getpagesize by 1171
	as the former is a system call that is deprecated.
	(doSyscall): Rename LIA64_stat to LIA64_old_stat, LIA64_lstat to
	LIA64_old_lstat, and LIA64_fstat to LIA64_old_fstat.
	(old_stat_host2lia64): Rename from stat_host2lia64.
	(struct lia64_old_stat): Rename from lia64_stat.
	(struct lia64_stat): New structure.
	(stat_host2lia64): New function.
	(doSyscall): Implement new versions of LIA64_stat, LIA64_lstat,
	and LIA64_fstat.
	(doSyscall): Treat clone2() same way as clone(): ordinary fork()
	or vfork() is supported, anything else fails.
	(doSyscall): Implement getdents64().  The d_type field is always
	set to DT_UNKNOWN for now (see linux/include/fs.h).  Once
	getdents64() is supported on most hosts, we can fix this.
	(doSyscall): Mention LIA64_pivot_root, LIA64_mincore, and
	LIA64_madvise, but treat them as unimplemented system calls for
	now.

	* syscall-linux.h: Update based on latest version.

	* syscall-linux.c (doSyscall): Remove ioperm() support; IA-64
	programs implement this at the user level.

2001-02-13  David Mosberger  <davidm@hpl.hp.com>

	* load.c (elfLoad): Define AT_PAGESZ unconditionally.  Add
	AT_CLKTCK.  If libc doesn't define AT_CLKTCK, define it here as 17
	(we can get rid of this once glibc-2.2 with kernel v2.4 is
	widespread enough).

	* Sync up with Mike's v0.943.

2000-12-21  David Mosberger  <davidm@hpl.hp.com>

	* data.c: Print ASCII data in correct order for little-endian
	machines.

	* version.c (VERSION): Change version to 0.873l4beta2.

2000-09-13  David Mosberger  <davidm@hpl.hp.com>

	* syscall-linux.c (LIA64_shmat): If shmid is not a known shmseg
	id, try to look up the segment's size via shmctl() and if that
	succeeds, create a new shmseg descriptor.  This should make it
	possible to inherit shmids between processes.
	(shmseg_new): Return pointer to newly created shmseg descriptor.

2000-09-12  David Mosberger  <davidm@hpl.hp.com>

	* sim.c (preInstStuff): Update icp by calling setIcp() after
	creating a signal handler frame (signal_invoke_handler()) or
	returning from one (signal_return()).
	(iCycleAppLoop): Check for NULL icp before doing operations that
	depend on non-NULL value.

2000-09-11  David Mosberger  <davidm@hpl.hp.com>

	* syscall-linux.c (signal_invoke_handler): Clear "info" before
	using it to avoid random pointers being used by the combfns
	routines.  Force update of cached instruction pointer by clearing
	icp to NULL.  Can't do setIcp() here because in the case of
	getting a signal while in sigsuspend(), icp will get updated in
	the return path from the break system call emulation.
	(signal_return): Ditto.  Don't set icp here, do it in sim.c instead.

2000-07-28  David Mosberger  <davidm@hpl.hp.com>

	* Released version 0.873l3.

2000-07-24  David Mosberger  <davidm@hpl.hp.com>

	* syscall-linux.c (LIA64_shmget): If we didn't create the shared
	memory segment, obtain the segment size via shmctl(IPC_STAT) and
	ignore the size that was passed in on entry (the shmget() call
	already verifies that arg1 <= segment size).

2000-07-13  David Mosberger  <davidm@hpl.hp.com>

	* syscall-linux.c (struct shmseg): New structure.
	(shmseg_list): New global variable to track list of
	attached shared memory segments.
	(cmsg_host2lia64): Remove unused variable "lia64_fd".
	(shmseg_new): New function.
	(shmseg_lookup_id): Ditto.
	(shmseg_lookup_addr): Ditto.
	(shmseg_free): Ditto.
	(LIA64_semctl): Implement IPC_RMID (only).
	(LIA64_msgctl): Ditto.
	(LIA64_shmctl): Ditto.
	(LIA64_shmget): Fix emulation.
	(LIA64_shmat): Ditto.
	(LIA64_shmdt): Ditto.

2000-07-06  David Mosberger  <davidm@hpl.hp.com>

	* memory.h (swapd): Make it host byte-order dependent.  This fixes
	a bug reported by Hiroshi Furukawa.

2000-06-09  David Mosberger  <davidm@hpl.hp.com>

	* memory.c (memXchgAdd): Handle access to unallocated page by
	calling unallocPageRd() and unallocPageWrt().
	(memXchgCond): Ditto.

2000-06-06  David Mosberger  <davidm@hpl.hp.com>

	* sim.c (iCycleSysLoop): Add back check & support for taken-branch
	and single-step faults.

2000-05-29  David Mosberger  <davidm@hpl.hp.com>

	* syscall-linux.c (doSyscall): Fix typo in readlink emulation:
	first argument to readlink must be buf, not malargbuf.

2000-05-15  David Mosberger  <davidm@hpl.hp.com>

	* Released version 0.873l2.	

	* syscall-linux.c (doSyscall): Fix getsockopt call.  arg4 is a
	_pointer_ to an int (socklen_t to be precise), not an int.  Also,
	fix size checking logic and use malargbuf/ENSURE_SIZE instead of
	the fixed size buffer (BUF).  Also fix setsockopt to use
	malargbuf/ENSURE_SIZE.

2000-05-11  David Mosberger  <davidm@hpl.hp.com>

	* syscall-linux.c (doSSC): Handle SSC_STOP.
	* ssc.h (SSC_STOP): Ditto.

2000-04-28  David Mosberger  <davidm@hpl.hp.com>

	* syscall-linux.c (initConsole): Fix error message ("to" was
	missing in "Unable to create console window").

2000-04-27  David Mosberger  <davidm@hpl.hp.com>

	* dwarf-linux.c (load_symbols): Don't fail if symbol count is
	zero.  Stripped binaries are quite fine.

	* load.c: Include "exportui.h" and "coreui.h".
	(elfSymLoad): Call initDwUnitTBL only if not running in batch mode.
	(elfLoad): Ditto.

2000-04-13  David Mosberger  <davidm@hpl.hp.com>

	* syscall-linux.c (doSyscall): Fix truncate and ftruncate: LENGTH
	argument is arg1, not arg2!  (Fixes emacs crash during undump.)
	Fixed bind, connect, accept, getsockname, sendto, recvfrom to let
	them handle arbitrary-sized socket addresses (fixes bug reported
	by Zeus).

1999-04-05  David Mosberger  <davidm@hpl.hp.com>

	* GNUmakefile (CFLAGS): Remove bogus warning about getting bad
	code with -O on x86.

1999-04-30  Stephane Eranian <eranian@hpl.hp.com>

	* Incorporated the network support into ski

	* modified syscall-linux.c to support networking in both 
	  user/kernel modes

	* syscall-linux.c: fix a bug in readConsole

1999-02-04  David Mosberger  <davidm@hpl.hp.com>

	* syscall-linux.c: Remove __NR_time (use __NR_gettimeofday instead).
