From 86c56b164ced14cadd054a37613fbddf896194da Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Mon, 16 Feb 2015 22:12:15 +0000 Subject: Fix MIPS __mips_isa_rev -Werror=undef build. I see an error In file included from ../sysdeps/mips/include/sys/asm.h:20:0, from ../sysdeps/mips/start.S:39: ../sysdeps/mips/sys/asm.h:421:5: error: "__mips_isa_rev" is not defined [-Werror=undef] #if __mips_isa_rev < 6 ^ cc1: some warnings being treated as errors in MIPS builds. As sys/asm.h is an installed header, it seems better to test for !defined __mips_isa_rev here, instead of defining it to 0 as done in sysdeps/unix/mips/sysdep.h, to avoid perturbing any code outside glibc that tests whether __mips_isa_rev is defined; this patch does so. * sysdeps/mips/sys/asm.h [__mips_isa_rev < 6]: Change condition to [!defined __mips_isa_rev || __mips_isa_rev < 6]. --- sysdeps/mips/sys/asm.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'sysdeps/mips') diff --git a/sysdeps/mips/sys/asm.h b/sysdeps/mips/sys/asm.h index 6c94cee..0ff8802 100644 --- a/sysdeps/mips/sys/asm.h +++ b/sysdeps/mips/sys/asm.h @@ -418,7 +418,7 @@ symbol = value # define PTR_ADDI addi # define PTR_SUB sub # define PTR_SUBI subi -#if __mips_isa_rev < 6 +#if !defined __mips_isa_rev || __mips_isa_rev < 6 # define PTR_ADDU add /* no u */ # define PTR_ADDIU addi /* no u */ # define PTR_SUBU sub /* no u */ -- cgit v1.1
