From bfa1881ab5b65175f97119b74ef127e08de882e1 Mon Sep 17 00:00:00 2001 From: Michelle McDaniel Date: Tue, 27 Mar 2018 13:23:45 -0700 Subject: [PATCH] Turn off PGO unprofiled warning on Linux (#17262) This warning will break the build when new files are added to the build that do not have PGO data, meaning that release builds will be broken until a new PGO collection can be run. We should not break the build if there are not counts for new files. --- pgosupport.cmake | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/pgosupport.cmake b/pgosupport.cmake index 96ff80af8d3a..bc331be6a587 100644 --- a/pgosupport.cmake +++ b/pgosupport.cmake @@ -36,7 +36,7 @@ function(add_pgo TargetName) if(UPPERCASE_CMAKE_BUILD_TYPE STREQUAL RELEASE OR UPPERCASE_CMAKE_BUILD_TYPE STREQUAL RELWITHDEBINFO) if(NOT CMAKE_CXX_COMPILER_VERSION VERSION_LESS 3.6) if(HAVE_LTO) - target_compile_options(${TargetName} PRIVATE -flto -fprofile-instr-use=${ProfilePath} -Wno-profile-instr-out-of-date) + target_compile_options(${TargetName} PRIVATE -flto -fprofile-instr-use=${ProfilePath} -Wno-profile-instr-out-of-date -Wno-profile-instr-unprofiled) set_property(TARGET ${TargetName} APPEND_STRING PROPERTY LINK_FLAGS " -flto -fuse-ld=gold -fprofile-instr-use=${ProfilePath}") else(HAVE_LTO) message(WARNING "LTO is not supported, skipping profile guided optimizations")
