Allow handler to be installed for other signals than SIGSEGV. * sysdeps/generic/register-dump.h: New file. * sysdeps/i386/register-dump.h: New file. * sysdeps/powerpc/register-dump.h: New file. * sysdeps/unix/sysv/linux/i386/profil-counter.h: Use macros from sigcontextinfo.h. * sysdeps/unix/sysv/linux/powerpc/profil-counter.h: Use i386 version. 1998-08-24 Geoff Keating * sysdeps/unix/sysv/linux/powerpc/sigcontextinfo.h: New file. 1998-08-09 Geoff Keating * sysdeps/unix/sysv/linux/powerpc/chown.c: New file. * sysdeps/unix/sysv/linux/powerpc/lchown.S: New file. * sysdeps/unix/sysv/linux/powerpc/syscalls.list: Add chown, remove getresuid, getresgid. 1998-08-16 Geoff Keating * sysdeps/unix/sysv/linux/powerpc/clone.S: Fix bugs. Set up stack pointer in userland. 1998-08-21 Andreas Schwab * sysdeps/unix/sysv/linux/sys/mount.h (MNT_FORCE): Define as enum and fix value. 1998-08-22 Andreas Schwab * elf/ldd.bash.in: Add missing quotes around $file. Make loop over arguments Bourne shell compatible. Don't exit unsuccessfully if nonelf returns successfully. Avoid duplicating most of the script. * sysdeps/unix/sysv/linux/ldd-rewrite.sed: Add missing quotes around $file. 1998-08-24 10:37 Andreas Schwab * libio/Versions (_IO_do_write, _IO_file_attach, _IO_file_close_it, _IO_file_finish, _IO_file_fopen, _IO_file_init, _IO_file_overflow, _IO_file_seekoff, _IO_file_setbuf, _IO_file_sync, _IO_file_underflow, _IO_file_write, _IO_file_xsputn): Added to GLIBC_2.1. * libio/fileops.c (_IO_do_write, _IO_file_attach, _IO_file_close_it, _IO_file_finish, _IO_file_fopen, _IO_file_init, _IO_file_overflow, _IO_file_seekoff, _IO_file_setbuf, _IO_file_sync, _IO_file_underflow, _IO_file_write, _IO_file_xsputn): Change the prefix to "_IO_new_". Added to GLIBC_2.1. * libio/libioP.h (_IO_do_write, _IO_file_attach, _IO_file_close_it, _IO_file_finish, _IO_file_fopen, _IO_file_init, _IO_file_overflow, _IO_file_seekoff, _IO_file_setbuf, _IO_file_sync, _IO_file_underflow, _IO_file_write, _IO_file_xsputn): Add prototypes for the prefix "_IO_new_". * libio/oldfileops.c (_IO_do_write, _IO_file_attach, _IO_file_close_it, _IO_file_finish, _IO_file_fopen, _IO_file_init, _IO_file_overflow, _IO_file_seekoff, _IO_file_setbuf, _IO_file_sync, _IO_file_underflow, _IO_file_write, _IO_file_xsputn): Added to GLIBC_2.0. * csu/initfini.c: Return to .text before __gmon_start__. * elf/elf.h (EM_FAKE_ALPHA): Rename from EM_OLD_ALPHA. (STO_MIPS_*): Rename from STO_*. (STB_MIPS_SPLIT_COMMON): Rename from STB_SPLIT_COMMON. (STO_ALPHA_NOPV, STO_ALPHA_STD_GPLOAD): New. * math/atest-exp.c (mpn_bitsize): Fix bit location calculation. (main): e3s is negative on zero. * math/atest-exp2.c: Likewise. 1998-08-23 Andreas Jaeger * Makerules (install): Add comment about absolute paths. --- sysdeps/powerpc/register-dump.h | 73 +++++++++++++++++++++++++++++++++++++++++ 1 file changed, 73 insertions(+) create mode 100644 sysdeps/powerpc/register-dump.h (limited to 'sysdeps/powerpc') diff --git a/sysdeps/powerpc/register-dump.h b/sysdeps/powerpc/register-dump.h new file mode 100644 index 0000000000..428b6073b9 --- /dev/null +++ b/sysdeps/powerpc/register-dump.h @@ -0,0 +1,73 @@ +/* Dump registers. + Copyright (C) 1998 Free Software Foundation, Inc. + This file is part of the GNU C Library. + Contributed by Ulrich Drepper , 1998. + + The GNU C Library is free software; you can redistribute it and/or + modify it under the terms of the GNU Library General Public License as + published by the Free Software Foundation; either version 2 of the + License, or (at your option) any later version. + + The GNU C Library is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
