From: Rich Felker Date: Wed, 15 Jun 2011 03:15:08 +0000 (-0400) Subject: restore use of .type in asm, but use modern @function (vs %function) X-Git-Tag: v0.7.11~46 X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=c7d19f9923c66a2ddb47272f1e8fec8b804f54c4;p=oweals%2Fmusl.git restore use of .type in asm, but use modern @function (vs %function) this seems to be necessary to make the linker accept the functions in a shared library (perhaps to generate PLT entries?) strictly speaking libc-internal asm should not need it. i might clean that up later. --- diff --git a/src/internal/i386/syscall.s b/src/internal/i386/syscall.s index 083db1ce..327d4cc0 100644 --- a/src/internal/i386/syscall.s +++ b/src/internal/i386/syscall.s @@ -1,4 +1,5 @@ .global __syscall +.type __syscall,@function __syscall: pushl %ebx pushl %esi diff --git a/src/internal/x86_64/syscall.s b/src/internal/x86_64/syscall.s index 931f44f6..6e0db09c 100644 --- a/src/internal/x86_64/syscall.s +++ b/src/internal/x86_64/syscall.s @@ -1,4 +1,5 @@ .global __syscall +.type __syscall,@function __syscall: movq %rdi,%rax movq %rsi,%rdi diff --git a/src/setjmp/i386/longjmp.s b/src/setjmp/i386/longjmp.s index b139d9fe..772d28dd 100644 --- a/src/setjmp/i386/longjmp.s +++ b/src/setjmp/i386/longjmp.s @@ -1,5 +1,7 @@ .global _longjmp .global longjmp +.type _longjmp,@function +.type longjmp,@function _longjmp: longjmp: mov 4(%esp),%edx diff --git a/src/setjmp/i386/setjmp.s b/src/setjmp/i386/setjmp.s index d53c1a63..586d4390 100644 --- a/src/setjmp/i386/setjmp.s +++ b/src/setjmp/i386/setjmp.s @@ -1,6 +1,9 @@ .global __setjmp .global _setjmp .global setjmp +.type __setjmp,@function +.type _setjmp,@function +.type setjmp,@function __setjmp: _setjmp: setjmp: diff --git a/src/setjmp/x86_64/longjmp.s b/src/setjmp/x86_64/longjmp.s index 70271bf5..444076f1 100644 --- a/src/setjmp/x86_64/longjmp.s +++ b/src/setjmp/x86_64/longjmp.s @@ -1,6 +1,8 @@ /* Copyright 2011 Nicholas J.
