HI: found mult-acc insns like madd.s/d are only used when -mfp64 is specified, as to codes, there macros defined as:
#define ISA_HAS_FP4 ((ISA_MIPS4 \ || (ISA_MIPS32R2 && TARGET_FLOAT64) \ <------only float 64 || ISA_MIPS64 \ || ISA_MIPS64R2) \ && !TARGET_MIPS16) #define ISA_HAS_FP_MADD4_MSUB4 ISA_HAS_FP4 why not use madd when fp32? Is there anything special with fp32? any clarification? Thanks very much -- Best Regards.
