From be10a86854716071a64f559e1f5bc94e145d0fdb Mon Sep 17 00:00:00 2001 From: Roland McGrath Date: Mon, 19 Feb 1996 20:54:38 +0000 Subject: *** empty log message *** Mon Feb 19 15:30:26 1996 Roland McGrath * stdio-common/tstscanf.c (main): Add check for "0" as %d. * sysdeps/stub/msync.c: Undo change of Jan 29; just two args. Only some systems have three args; let them define their own stub. * sysdeps/generic/dl-sysdep.c: Declare _dl_secure. * sysdeps/generic/machine-gmon.h: New file. * gmon/Makefile (distribute): Add machine-gmon.h. * gmon/mcount.c: Undo changes of Feb 13. Include "machine-gmon.h". Sun Feb 18 13:24:06 1996 Roland McGrath * sysdeps/unix/sysv/linux/direct.h: File removed, since it is identical to unix/common/direct.h. * sysdeps/unix/Makefile [no_deps]: Don't include s-proto.d. * sysdeps/unix/sysv/linux/Makefile (sysdep_routines): Don't add ipc. * stdio-common/Makefile (tests): Remove scanf6. * sysdeps/unix/sysv/linux/Makefile (non-lib.a): Append libieee.a. * time/mktime.c (mktime): Move static variable localtime_offset to file scope. * stdio-common/vfscanf.c: Put '0' in buffer before scanning for %i base indicator. Thu Feb 15 16:56:17 1996 Andreas Schwab * sysdeps/m68k/dl-machine.h (elf_machine_load_address): Corrected. (ELF_MACHINE_BEFORE_RTLD_RELOC): Define. (_dl_runtime_resolve): Save %a1 as well. (ELF_MACHINE_RUNTIME_FIXUP_ARGS): Add second dummy arg. (elf_machine_relplt): Define. * elf/dl-runtime.c: Include possible extra args in declaration of fixup. --- sysdeps/m68k/bsd-_setjmp.S | 2 +- sysdeps/m68k/bsd-setjmp.S | 2 +- sysdeps/m68k/dl-machine.h | 27 ++++++++++++++++++++++----- sysdeps/unix/closedir.c | 6 +++--- sysdeps/unix/dirstream.h | 7 +++---- sysdeps/unix/opendir.c | 26 ++++++++++++-------------- sysdeps/unix/readdir.c | 4 +++- sysdeps/unix/seekdir.c | 6 +++--- sysdeps/unix/telldir.c | 4 ++-- 9 files changed, 50 insertions(+), 34 deletions(-) (limited to 'sysdeps') diff --git a/sysdeps/m68k/bsd-_setjmp.S b/sysdeps/m68k/bsd-_setjmp.S index 69aa7de04c..db777cf67d 100644 --- a/sysdeps/m68k/bsd-_setjmp.S +++ b/sysdeps/m68k/bsd-_setjmp.S @@ -23,7 +23,7 @@ Cambridge, MA 02139, USA. */ #include -#ifdef MOTOROLA_SYNTAX +#if defined (MOTOROLA_SYNTAX) || defined (ELF_SYNTAX) #define d0 %d0 #define d1 %d1 #define PUSH(reg) move.l reg, -(%sp) diff --git a/sysdeps/m68k/bsd-setjmp.S b/sysdeps/m68k/bsd-setjmp.S index c853516824..c1794978bc 100644 --- a/sysdeps/m68k/bsd-setjmp.S +++ b/sysdeps/m68k/bsd-setjmp.S @@ -23,7 +23,7 @@ Cambridge, MA 02139, USA. */ #include -#ifdef MOTOROLA_SYNTAX +#if defined (MOTOROLA_SYNTAX) || defined (ELF_SYNTAX) #define d0 %d0 #define d1 %d1 #define PUSH(reg) move.l reg, -(%sp) diff --git a/sysdeps/m68k/dl-machine.h b/sysdeps/m68k/dl-machine.h index 2208cd2259..8cbb97787c 100644 --- a/sysdeps/m68k/dl-machine.h +++ b/sysdeps/m68k/dl-machine.h @@ -52,9 +52,22 @@ elf_machine_got (void) static inline Elf32_Addr elf_machine_load_address (void) { - ... + Elf32_Addr addr; + asm ("here: lea here(%%pc), %0\n" + " sub.l %#here, %0" + : "=a" (addr)); + return addr; } +/* The `subl' insn above will contain an R_68K_RELATIVE relocation + entry intended to insert the run-time address of the label `here'. + This will be the first relocation in the text of the dynamic + linker; we skip it to avoid trying to modify read-only text in this + early stage. */ +#define ELF_MACHINE_BEFORE_RTLD_RELOC(dynamic_info) \ + ((dynamic_info)[DT_RELA]->d_un.d_ptr += sizeof (Elf32_Rela), \ + (dynamic_info)[DT_RELASZ]->d_un.d_val -= sizeof (Elf32_Rela)) + /* Perform the relocation specified by RELOC and SYM (which is fully resolved).
