From 4194bc660f0768b1e0999f4e0a7723a35b00953c Mon Sep 17 00:00:00 2001 From: Richard Henderson Date: Mon, 6 Apr 1998 19:08:46 +0000 Subject: * elf/dl-runtime.c (fixup, profile_fixup): The final arg to _dl_lookup_*symbol is DL_LOOKUP_NOPLT not ELF_MACHINE_JMP_SLOT. * elf/elf.h (EM_SPARC64): Remove. (EM_SPARC32PLUS, EM_SPARCV9): Add. (HWCAP_SPARC_V9): Add. * elf/ldsodefs.h (_dl_hwcap): Declare. * sysdeps/sparc/sparc32/dl-machine.h (_dl_hwcap, _dl_hwcap_mask): Weaken so dlopen from static progies works. (WEAKADDR): New macro. (elf_machine_matches_host): Accept EM_SPARC32PLUS on a v9 cpu. (LD_SO_PRELOAD): New macro. (elf_machine_fixup_plt): Cope with weak _dl_hwcap. (elf_machine_rela): Weaken _dl_rtld_map. * sysdeps/unix/sysv/linux/sparc/sparc32/clone.S: Rename __libc_clone to __clone, and remove the later's alias. * sysdeps/unix/sysv/linux/sparc/sparc64/clone.S: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc32/sigaction.c: Copy to/from the kernel's structure. 1998-04-06 Jakub Jelinek * elf/dl-runtime.c (fixup, profile_fixup): The final arg to _dl_lookup_*symbol is DL_LOOKUP_NOPLT not ELF_MACHINE_JMP_SLOT. * elf/elf.h (EM_SPARC64): Remove.
