    MIPS[64]: Disable fusion multiple-accumulate instructions · ee7281f8
    ivica.bogosavljevic authored
    MIPS[64]R6 supports only fusion multiply-accumulate instructions, and using
    these causes failures of several tests that expect exact floating-point
    results. Therefore we disable fusion multiply-accumulate in both emitted and
    compiled code on R6.
    
    TEST=cctest/test-run-machops/RunFloat64MulAndFloat64Add1,mjsunit/es6/math-expm1.js
    mjsunit/es6/math-fround.js,mjsunit/compiler/multiply-add.js
