Make profiling work for ELF. gprof now autodetects the format of the executable file, so it will work for both a.out and ELF format files. I have split the object format specific code into separate source files. It's cleaner than it was before, but it's still pretty crufty. Don't cheat on your make world for this update. A lot of things have to be rebuilt for it to work, including the compiler and all of the profiled libraries. 1998-09-07 23:32:00 +00:00			`OBJS+= gcrt1.o`
Switch to using ".So" as the extension for PIC object files rather than ".so". The old extension conflicted with well-established naming conventions for dynamically loadable modules. The "clean" targets continue to remove ".so" files too, to deal with old systems. 1999-01-09 21:51:00 +00:00			`SOBJS= crtbegin.So crtend.So`
Add "-fkeep-inline-functions" to CFLAGS so that higher optimization levels (-O3 and above) won't remove essential code. Many thanks to Dmitrij Tejblum <dima@tejblum.dnttm.rssi.ru> for pointing out that it was the optimizer's removal of this code that caused make world with -O3 to break. With this change, make buildworld now completes. 1999-03-15 21:56:54 +00:00			`CFLAGS+= -elf -Wall -fkeep-inline-functions`
