Update.
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> * math/libm-test.c (identities): Change epsilon. * sysdeps/i386/fpu/bits/mathinline.h: Correct arguments to fabs, fabsf, fabsl, __fabsl. * sysdeps/libm-i387/e_remainderl.S: Pop extra value from FPU stack. * sysdeps/libm-ieee754/s_csinhl.c: Include <fenv.h>.
