Import C startup files for ELF support. Submitted by: John Polstra <jdp@polstra.com> 1998-03-07 20:27:11 +00:00
* Bring back the guts of crt{i,n}.S. This allows C++ exceptions to work when using the egcs and gcc-devel ports, along with GCC built from stock public FSF sources. With out this change, FreeBSD will be removed from the list of systems GCC 3.0 must be evaluated on before release. With the effort some of us put into getting FreeBSD on this list, we should not turn this effort into a waste, else we might not be worth fighting for in the future. (note that Alpha and IA-64 versions of crt{i,n}.S are needed) * Switch from our own crt{begin,in} to those created from GCC's crtstuff.c. This will allow us to switch to DWARF2 exceptions in the future, along with staying in sync with any future GCC requirements. * Break out our ELF branding bits into a seperate file. Currently this is now included by our crt1.c files (since this functionality was part of our native crtbegin.c). Later crtbrand.o will be merged in the creation of crti.o. 2000-10-28 21:26:48 +00:00			`SRCS= crt1.c crti.S crtn.S`

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`
Removed "-fkeep-inline-functions" from CFLAGS, since it now has no effect except to generate spurious warnings about a system header <sys/param.h> having some inline functions (the bswap family). This backs out the main part of rev.1.5 (which was the only part left). The problem fixed by rev.1.5 of the Makefile went away in rev.1.5 of ../common/crtbegin.c when the references to do_ctors() and do_dtors() in the latter were moved from inline asm to C code. This leaves the problem that implementation details cause warnings. Discussed with: jdp 2002-04-29 13:07:20 +00:00			`CFLAGS+= -elf -Wall \`
Do not use __progname directly (except in [gs]etprogname(3)). Also, make an internal _getprogname() that is used only inside libc. For libc, getprogname(3) is a weak symbol in case a function of the same name is defined in userland. 2002-03-29 22:43:43 +00:00			`-I${.CURDIR}/../common \`
