* sysdeps/generic/expm1.c: #undef expm1 before weak_alias.
|
||||
|
||||
* libc-symbols.h [! HAVE_ASM_SET_DIRECTIVE] (strong_alias,
|
||||
strong_alias_asm): Use `foo = bar' syntax instead.
|
||||
* configure.in: Fix AC_ARG_WITH uses; check for --with-fp. Move
|
||||
$host_os checks to set gnu_ld/as and elf before sysdirs
|
||||
generation. Fix $with_fp test.
|
||||
[$elf=yes]: Prepend MACHINE/elf directory.
|
||||
|
||||
* elf/libelf.h (elf_hash): Use XOR instead of ANDN when the bits
|
||||
being cleared are already known to be set. Thanks Ulrich.
