1gcc 4.4 did this: The MIPS port no longer recognizes the h asm constraint. It was necessary to remove this constraint in order to avoid generating unpredictable code sequences. 2 3so the libmad build with gcc-4.5.0 was failing. 4 5Found a solution here: 6 7http://us.generation-nt.com/answer/bug-568418-libmad0-dev-mpg321-compilation-errors-mips-mipsel-architectures-help-169033451.html 8 9Upstream-Status: Pending 10 112010/07/29 12Nitin A Kamble <nitin.a.kamble@intel.com> 13 14--- a/fixed.h 15+++ b/fixed.h 16@@ -297,6 +297,15 @@ mad_fixed_t mad_f_mul_inline(mad_fixed_t 17 18 /* --- MIPS ---------------------------------------------------------------- */ 19 20+# elif defined(FPM_MIPS) && (defined(__clang__) || __GNUC__ > 4 || (__GNUC__ == 4 && __GNUC_MINOR__ >= 4)) 21+ typedef unsigned int u64_di_t __attribute__ ((mode (DI))); 22+# define MAD_F_MLX(hi, lo, x, y) \ 23+ do { \ 24+ u64_di_t __ll = (u64_di_t) (x) * (y); \ 25+ hi = __ll >> 32; \ 26+ lo = __ll; \ 27+ } while (0) 28+ 29 # elif defined(FPM_MIPS) 30 31 /* 32
