From 1c497005ee58fd237646a49231b73fd3ea79e2d5 Mon Sep 17 00:00:00 2001 From: Rich Felker Date: Wed, 31 May 2017 21:49:44 -0400 Subject: [PATCH] remove long-obsolete clang workarounds from mips* syscall_arch.h files at one point, clang reportedly failed to support the asm register constraints needed for inline syscalls. versions of clang that old have much bigger problems that preclude using them to compile musl libc. --- arch/mips/syscall_arch.h | 41 -------------------- arch/mips64/syscall_arch.h | 75 ------------------------------------- arch/mipsn32/syscall_arch.h | 41 -------------------- 3 files changed, 157 deletions(-) diff --git a/arch/mips/syscall_arch.h b/arch/mips/syscall_arch.h index 39c0ea32..3ac4da21 100644 --- a/arch/mips/syscall_arch.h +++ b/arch/mips/syscall_arch.h @@ -20,8 +20,6 @@ static inline void __stat_fix(long p) } #endif -#ifndef __clang__ - static inline long __syscall0(long n) { register long r7 __asm__("$7");
