f41c80910d
1997-08-24 12:24 Ulrich Drepper <drepper@cygnus.com>
* configure.in (INSTALL): Quote `$'.
* libc.map: Add __xpg_basename.
* csu/Makefile (initfini.s): Disable optimization.
* elf/dl-deps.c: Implement handling of DL_FILTER.
* elf/dl-load.c (_dl_init_paths): Add error check.
* intl/finddomain.c (_nl_find_domain): Correct comment.
* intl/localealias.c: Include <bits/libc-lock.h> not <libc-lock.h>.
* libio/stdio.h: Make {,v}snprintf available if __USE_BSD.
Change extern inline functions to work correctly in C++.
* locale/iso-4217.def: Update for more recent ISO 4217 version.
* locale/loadlocale.c (_nl_load_locale): Add cast.
* manual/message.texi: Finish gettext section.
* posix/getopt_init.c: Don't use relative #include path.
(__getopt_clean_environment): Change function to take pointer to
environment as argument. Optimize generation of test string a bit.
* sysdeps/unix/sysv/linux/init-first.c: Call __getopt_clean_environment
with additional argument.
* poisx/glob.c: Add prototype for next_brace_sub.
* sysdeps/generic/dl-sysdep.c: Recognize AT_BASE value on auxiliary
vector.
* sysdeps/i386/dl-machine.h (elf_machine_load_address): Rewrite
to not generate relocation entry. Suggested by Richard Henderson.
(ELF_MACHINE_BEFORE_RTLD_RELOC): Removed.
(elf_machine_runtime_setup): Add .aligns.
* sysdeps/i386/fpu/fraiseexcpt.c: Add volatile to asms.
* sysdeps/i386/fpu/bits/mathinline.h: Partially undo change of
1997-08-14 03:14. gcc 2.7.2* is really broken in some aspects.
* sysdeps/standalone/i386/i386.h: Clean up asm statements a bit.
* sysdeps/standalone/i960/i960ca.h: Likewise.
1997-08-22 19:04 Richard Henderson <rth@cygnus.com>
* elf/rtld.c (_dl_start): Init _dl_rtld_map.l_opencount due to
undocumented test addition in _dl_map_object.
Support ET_EXEC versions of ld.so, for debugging at least:
* elf/dl-load.c (_dl_map_object): Add_name_to_object could get
called despite the DT_SONAME != NULL test, segfaulting. Simplify
the code here as well.
* elf/dl-lookup.c (do_lookup): Skip objects with no symtab.
(_dl_setup_hash): Likewise for hash tables.
* elf/dl-version.c (_dl_check_map_versions): Likewise for strtabs.
* elf/rtld.c (_dl_start): Likewise for rpath.
(_dl_rtld_libname2): New variable.
(dl_main): Use it to add an soname for ourselves when we don't have
one of our own. Base it on the target's .interp.
(dl_main): Again, skip printing of objects that don't have strtabs.
Sparc 32 merge:
* elf/dl-runtime.c (ELF_FIXUP_RETURN_VALUE): Provide default value.
(fixup): Simplify code. Use ELF_FIXUP_RETURN_VALUE.
(profile_fixup): Likewise, though this still needs fixing for
Sparc32 and PPC.
* sysdeps/powerpc/dl-machine.h: Transmute ELF_FIXUP_RETURNS_ADDRESS
to ELF_FIXUP_RETURN_VALUE.
* sysdeps/sparc/sparc32/dl-machine.h: Implement lazy relocation.
Fix up _dl_start_user to handle _dl_skip_args properly.
Use _dl_hwcap to determine if "flush" is available/needed.
* sysdeps/sparc/configure.in: Remove. It doesn't actually do
anything anymore, and what it did do is done somewhere else.
* sysdeps/sparc/configure: Likewise.
* sysdeps/sparc/fpu/bits/mathdef.h (FP_ILOGB0, FP_ILOGBNAN): New.
* sysdeps/sparc/fpu/fraiseexcpt.c: Rearrange for smaller code.
* sysdeps/sparc/sparc32/Makefile: Fix sparc->sparc/sparc32 bits
in divrem expansions.
* sysdeps/unix/sysv/linux/sparc/sparc32/sysdep.h (END, LOC): New
definitions for assembly syntax differences.
* sysdeps/sparc/sparc32/__longjmp.S: %g6,%g7 are reserved to the
"system". Use %g2,%g3 instead. Use new local label macro.
* sysdeps/sparc/sparc32/add_n.S: Use <sysdep.h> and ENTRY, END,
and LOC for proper assembly headers/footers.
* sysdeps/sparc/sparc32/addmul_1.S: Likewise.
* sysdeps/sparc/sparc32/alloca.S: Likewise.
* sysdeps/sparc/sparc32/dotmul.S: Likewise.
* sysdeps/sparc/sparc32/lshift.S: Likewise.
* sysdeps/sparc/sparc32/mul_1.S: Likewise.
* sysdeps/sparc/sparc32/rshift.S: Likewise.
* sysdeps/sparc/sparc32/sparcv8/addmul_1.S: Likewise.
* sysdeps/sparc/sparc32/sparcv8/mul_1.S: Likewise.
* sysdeps/sparc/sparc32/sparcv8/submul_1.S: Likewise.
* sysdeps/sparc/sparc32/sparcv8/udiv_qrnnd.S: Likewise.
* sysdeps/sparc/sparc32/sub_n.S: Likewise.
* sysdeps/sparc/sparc32/submul_1.S: Likewise.
* sysdeps/sparc/sparc32/udiv_qrnnd.S: Likewise.
* sysdeps/sparc/sparc32/umul.S: Likewise.
* sysdeps/sparc/sparc32/divrem.m4: Likewise.
* sysdeps/sparc/sparc32/rem.S: Regenerate.
* sysdeps/sparc/sparc32/sdiv.S: Regenerate.
* sysdeps/sparc/sparc32/udiv.S: Regenerate.
* sysdeps/sparc/sparc32/urem.S: Regenerate.
* sysdeps/sparc/sparc32/sparcv8/dotmul.S: New file.
* sysdeps/sparc/sparc32/sparcv8/rem.S: New file.
* sysdeps/sparc/sparc32/sparcv8/sdiv.S: New file.
* sysdeps/sparc/sparc32/sparcv8/udiv.S: New file.
* sysdeps/sparc/sparc32/sparcv8/umul.S: New file.
* sysdeps/sparc/sparc32/sparcv8/urem.S: New file.
* sysdeps/sparc/sparc32/bsd-_setjmp.S: Dike out.
* sysdeps/sparc/sparc32/bsd-setjmp.S: Likewise.
* sysdeps/sparc/sparc32/setjmp.S: Add _setjmp and setjmp entry points.
* sysdeps/unix/sysv/linux/sparc/sparc32/__sigtrampoline.S:
Clean up PIC code.
* sysdeps/sparc/sparc32/elf/start.S: New file, slightly modified
from the sparc64 version.
* sysdeps/sparc/sparc32/elf/start.c: Removed.
* sysdeps/unix/sysv/linux/sparc/sparc32/init-first.h: Rewrite in
assembly based on the sparc64 version.
* sysdeps/sparc/sparc32/fpu/bits/fenv.h: Duh. Use proper syntax
for manipulating %fsr.
* sysdeps/sparc/sparc32/fpu/fpu_control.h: Make IEEE conformance
be the default.
* elf/elf.h (HWCAP_SPARC_*): New definitions.
* elf/rtld.c (_dl_hwcap): New variable.
* sysdeps/generic/dl-sysdep.c (_dl_sysdep_start): Record AT_HWCAP.
* sysdeps/unix/sysv/linux/sparc/sparc32/getpagesize.c: New file.
Attempt to get hold of the page size based on what we might have
been told at startup time in _dl_pagesize. This will be obsolete
when I finish the kernel hooks for a proper sysconf(), stay tuned.
Sparc 64 merge:
* sysdeps/sparc/sparc64/dl-machine.h (ELF_FIXUP_RETURN_VALUE): New.
Figure out the right thing to return based on the .plt format.
* sysdeps/sparc/sparc64/fpu/fpu_control.h: Update comment.
* sysdeps/unix/sysv/linux/sparc/sparc64/bits/types.h (__dev_t):
Should have been 64-bits wide.
* sysdeps/unix/sysv/linux/sparc/sparc64/init-first.h: sll->sllx,
optimize for branch delay slot usage.
1997-08-22 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>
* csu/Makefile ($(objpfx)crt%.o): Fix a missing *.so -> *.os
change.
1997-08-20 Andreas Jaeger <aj@arthur.rhein-neckar.de>

* sysdeps/i386/fpu/bits/mathinline.h: Correct arguments to fabs,
fabsf, fabsl, __fabsl.

* sysdeps/libm-ieee754/s_csinhl.c: Include <fenv.h>.
