From 4c040a649b610ab1a0b5aa30c01148bffa9e2f4b Mon Sep 17 00:00:00 2001 From: Peter Schauer Date: Sat, 5 Mar 1994 22:39:47 +0000 Subject: [PATCH] * internal.h: Remove Elf32_*, Elf64_* typedefs. These names cause conflicts with system headers, e.g. link.h in gdb/solib.c. Combine 32- and 64-bit versions of *_Internal_Dyn. * common.h: Replace uses of Elf64_Word, Elf64_Xword typedefs by their expansion. * mips.h: Replace uses of Elf32_Word, Elf32_Sword, Elf32_Addr typedefs by their expansion. Add DT_MIPS_RLD_MAP definition. --- include/elf/ChangeLog | 19 +++++++ include/elf/mips.h | 113 ++++++++++++++++++++++++++++++++++++------ 2 files changed, 116 insertions(+), 16 deletions(-) diff --git a/include/elf/ChangeLog b/include/elf/ChangeLog index d0635d21e43..0fc2bb3376e 100644 --- a/include/elf/ChangeLog +++ b/include/elf/ChangeLog @@ -1,3 +1,22 @@ +Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de) + + * internal.h: Remove Elf32_*, Elf64_* typedefs.
