From ceb2d9aaa86cc3d3d4accc294751c98d49bdc5c2 Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Thu, 27 Feb 1997 06:01:16 +0000 Subject: update from main archive 970226 1997-02-27 05:12 Ulrich Drepper * manual/Makefile: Add rules to run and distribute xtract-typefun. * manual/xtract-typefun.awk: New file. Script to extract function, variable, macro anchor to put into the `dir' file. * manual/signal.texi: Document difference between SysV and BSD signal(3) function and add documentation for sysv_signal. * sysdeps/libm-i387/e_acoshl.c: Clear upper half of word containing exponent before comparing. 1997-02-27 01:13 Ulrich Drepper * sysdeps/generic/netinet/in.h (htonl, htons, ntohl, ntohs): Change prototypes to use types with explicit width. `unsigned long' is different on 64 bit systems. * sysdeps/unix/sysv/linux/netinet/in.h: Likewise. * sysdeps/generic/htonl.c: Likewise. * sysdeps/generic/htons.c: Likewise. * sysdeps/generic/ntohl.c: Likewise. * sysdeps/generic/ntohs.c: Likewise. Suggested by a sun . 1997-02-26 08:30 Andreas Jaeger * math/math.h: Include <__math.h> if __NO_MATH_INLINES is not defined and we want optimization. 1997-02-27 01:13 Ulrich Drepper * sysdeps/generic/netinet/in.h (htonl, htons, ntohl, ntohs): Change prototypes to use types with explicit width. `unsigned long' is different on 64 bit systems. Suggested by a sun . 1997-02-02 19:53 Andreas Schwab * misc/getpass.c: Don't disable canonical input. Reverted patch of Mon Jan 6 01:35:29 1997. 1996-12-14 22:07 Andreas Schwab * libio/libioP.h (_IO_finish_t): Take additional parameter, to match the hidden __in_chrg parameter of the destructor. (_IO_FINISH): Pass zero for it. * libio/genops.c (_IO_default_finish): Add second parameter, which is ignored. * libio/memstream.c (_IO_mem_finish): Likewise. * libio/fileops.c (_IO_mem_finish): Likewise. * libio/strops.c (_IO_str_finish): Likewise. All callers changed. 1997-02-27 00:23 H.J. Lu * time/Makefile: Avoid using patterns in dependencies. 1997-02-26 00:56 Miguel de Icaza * elf/rtld.c: Make _dl_start static. Otherwise the linker on the SPARC will convert the call _dl_start into a call into the PLT. * elf/rtld.c (_dl_start): On the SPARC we need to adjust the value of arg to make it point to the actual values. * sysdeps/sparc/elf/DEFS.h: New ELF specific version. * sysdeps/sparc/Dist: Mention sysdeps/sparc/elf/DEFS.h. * sysdeps/sparc/bsd-_setjmp.S, sysdeps/sparc/bsd-setjmp.S: Make them PIC aware. * sysdeps/sparc/dl-machine.h (elf_machine_load_address): Implemented. (elf_machine_rela): Make it compile; fix existing relocation types; add unhandled relocation types. (ELF_ADJUST_ARG): Get pointer to arguments at program startup. (RTLD_START): Initial implementation, not yet finished. * sysdeps/sparc/elf/start.S: Fix. * sysdeps/sparc/fpu_control.h: Remove duplicate declaration of __setfpucw. * sysdeps/sparc/divrem.m4: Make compilable under Linux. * sysdeps/sparc/rem.S, sysdeps/sparc/sdiv.S, sysdeps/sparc/udiv.S, sysdeps/sparc/urem.S : Regenerated. * sysdeps/sparc/setjmp.S: Make it PIC aware. * sysdeps/unix/sysv/linux/sparc/__sigtrampoline.S: Define __ASSEMBLY__ before using kernel header. * sysdeps/unix/sysv/linux/sparc/Makefile: Use -mv8 flag to compile rtld.c. * sysdeps/unix/sysv/linux/sparc/brk.c: Implement. * sysdeps/unix/sysv/linux/sparc/profil-counter.h: Remove code to handle old signals. * sysdeps/unix/sysv/linux/sparc/sigaction.c: Implements sigaction for all Linux/SPARC kernels. * sysdeps/unix/sysv/linux/sparc/syscall.S: Add code to store errno using __errno_location. * sysdeps/unix/sysv/linux/sparc/sysdep.h: Add various handler macros for assembler sources. * sysdeps/unix/sysv/linux/sparc/errno.c: Define errno. 1997-02-25 16:02 Andreas Schwab * elf/rtld.c (dl_main): Remove dead code that is never executed. Rename local variable l to main_map where it is used to point to the load_map for the executable. 1997-02-25 15:03 Andreas Schwab * elf/dl-version.c (_dl_check_all_versions): Ignore libraries that could not be found. 1997-02-24 23:18 Andreas Schwab * Makerules: Generate implicit object suffix rules automagically. (o-iterator): Move before first use. * Makeconfig (all-object-suffixes): Add .bo suffix. 1997-02-25 15:11 Ulrich Drepper * sysdeps/libm-i387/e_acoshf.S (__ieee754_acoshf): Test correct word on stack for overflow. C++.
