From e5bb165bed7be4176914672d25ff8e286b6fba49 Mon Sep 17 00:00:00 2001 From: Szabolcs Nagy Date: Mon, 24 Feb 2014 23:16:29 +0100 Subject: mips: add mips-sf subarch support (soft-float) Userspace emulated floating-point (gcc -msoft-float) is not compatible with the default mips abi (assumes an FPU or in kernel emulation of it). Soft vs hard float abi should not be mixed, __mips_soft_float is checked in musl's configure script and there is no runtime check. The -sf subarch does not save/restore floating-point registers in setjmp/longjmp and only provides dummy fenv implementation. --- arch/mips/reloc.h | 8 +++++++- 1 file changed, 7 insertions(+), 1 deletion(-) (limited to 'arch/mips/reloc.h') diff --git a/arch/mips/reloc.h b/arch/mips/reloc.h index 07fa10a7..4ca81257 100644 --- a/arch/mips/reloc.h +++ b/arch/mips/reloc.h @@ -8,7 +8,13 @@ #define ENDIAN_SUFFIX "" #endif -#define LDSO_ARCH "mips" ENDIAN_SUFFIX +#ifdef __mips_soft_float +#define FP_SUFFIX "-sf" +#else +#define FP_SUFFIX "" +#endif + +#define LDSO_ARCH "mips" ENDIAN_SUFFIX FP_SUFFIX #define IS_COPY(x) ((x)==R_MIPS_COPY) #define IS_PLT(x) 1 -- cgit v1.2.1
