Update.
1998-06-07 13:32 Ulrich Drepper <drepper@cygnus.com> * libc.map: Add _dl_profile. * elf/dl-reloc.c (_dl_relocate_object): Take extra argument, pass this to ELF_DYNAMIC_RELOCATE. Always allocate array for relocation result if LD_PROFILE is defined. * elf/ldsodefs.h: Adjust prototypes. * elf/dl-open.c (_dl_open): Call relocation function with extra argument. * elf/rtld.c: Likewise. * elf/dl-profile.c (_dl_mcount): Don't mark as internal function. Correct loop condition. * elf/dynamic-link.h: Don't examine _dl_profile variable, pass consider_profile to runtime setup function. * sysdeps/i386/dl-machine.h (elf_machine_runtime_setup): Use _dl_runtime_profile for all shared objects if LD_PROFILE is defined. * elf/dl-support.c: Define __libc_stack_end. * elf/rtld.c: Likewise. * sysdeps/generic/libc-start.c: Store last stack address in __libc_stack_end. * sysdeps/i386/dl-machine.h (_dl_start_user): Store stack address. * sysdeps/i386/elf/start.s: Call __libc_start_main with extra argument. * elf/elf.h: Include <features.h>, not <sys/cdefs.h>. Include <stdint.h>, not <inttypes.h>. * elf/sprof.c: Implement flat profiling. * libio/fgetc.c: Call _IO_cleanup_region_end with 0 and call _IO_funlockfile explicitly. * libio/fileops.c: Likewise. * libio/fputc.c: Likewise. * libio/freopen.c: Likewise. * libio/freopen64.c: Likewise. * libio/fseek.c: Likewise. * libio/fseeko.c: Likewise. * libio/fseeko64.c: Likewise. * libio/ftello.c: Likewise. * libio/ftello64.c: Likewise. * libio/getc.c: Likewise. * libio/getchar.c: Likewise. * libio/iofclose.c: Likewise. * libio/iofflush.c: Likewise. * libio/iofgetpos.c: Likewise. * libio/iofgetpos64.c: Likewise. * libio/iofgets.c: Likewise. * libio/iofputs.c: Likewise. * libio/iofread.c: Likewise. * libio/iofsetpos.c: Likewise. * libio/iofsetpos64.c: Likewise. * libio/ioftell.c: Likewise. * libio/iofwrite.c: Likewise. * libio/iogetdelim.c: Likewise. * libio/iogets.c: Likewise. * libio/ioputs.c: Likewise. * libio/ioseekoff.c: Likewise. * libio/ioseekpos.c: Likewise. * libio/iosetbuffer.c: Likewise. * libio/iosetvbuf.c: Likewise. * libio/ioungetc.c: Likewise. * libio/iovsprintf.c: Likewise. * libio/iovsscanf.c: Likewise. * libio/oldfileops.c: Likewise. * libio/oldiofclose.c: Likewise. * libio/peekc.c: Likewise. * libio/putc.c: Likewise. * libio/putchar.c: Likewise. * libio/rewind.c: Likewise. * malloc/mtrace.c: Pretty print. * misc/mntent.h (struct mentent): Make string elements const char *. * nis/nis_printf.c: Optimize I/O a little bit. * signal/Makefile (distribute): Add sigset-cvt-mask.h. * sysdeps/generic/sigset-cvt-mask.h: New file. * sysdeps/unix/sysv/linux/sigset-cvt-mask.h: New file. * sysdeps/unix/sysv/sysv4/sigset-cvt-mask.h: New file. * sysdeps/posix/sigvec.c: Rewrite the use definitions from sigset-cvt-mask.h to do the dirty work. Patches by Joe Keane. * sysdeps/posix/mkstemp.c: Save one precious byte of rodata. * sysdeps/unix/sysv/linux/i386/sysdep.h: Rewrite PSEUDO etc to make syscall_error label in case of PIC anonymous. * sysdeps/unix/sysv/linux/i386/i686/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/i386/clone.S: Adapt for this change. * sysdeps/unix/sysv/linux/i386/mmap.S: Adapt for this change. * sysdeps/unix/sysv/linux/i386/s_pread64.S: Adapt for this change. * sysdeps/unix/sysv/linux/i386/s_pwrite64.S: Adapt for this change. * sysdeps/unix/sysv/linux/i386/socket.S: Adapt for this change. * sysdeps/unix/sysv/linux/i386/syscall.S: Adapt for this change.
