| // Routines used to provide debug messages and information from libomptarget | ||
| // and plugin RTLs to the user. | ||
| // | ||
| // Each plugin RTL and libomptarget define TARGET_NAME and DEBUG_PREFIX for use | ||
| // when sending messages to the user. These indicate which RTL sent the message | ||
| // | ||
| // Debug and information messages are controlled by the environment variables | ||
| // LIBOMPTARGET_DEBUG and LIBOMPTARGET_INFO which is set upon initialization | ||
| // of libomptarget or the plugin RTL. | ||
| // | ||
| // To printf a pointer in hex with a fixed width of 16 digits and a leading 0x, | ||
| // use printf("ptr=" DPxMOD "...\n", DPxPTR(ptr)); | ||
| // | ||
| // DPxMOD expands to: | ||
| // "0x%0*" PRIxPTR | ||
| // where PRIxPTR expands to an appropriate modifier for the type uintptr_t on a | ||
| // specific platform, e.g. "lu" if uintptr_t is typedef'd as unsigned long: | ||
| // "0x%0*lu" | ||
| // | ||
| // Ultimately, the whole statement expands to: | ||
| // printf("ptr=0x%0*lu...\n", // the 0* modifier expects an extra argument | ||
| // // specifying the width of the output | ||
| // (int)(2*sizeof(uintptr_t)), // the extra argument specifying the width | ||
| // // 8 digits for 32bit systems | ||
| // // 16 digits for 64bit | ||
| // (uintptr_t) ptr); | ||
