43 | # -Wa,-isa= tuning implies -Wa,-dsp for the versions of binutils that | |
44 | # support it, while -Wa,-dsp by itself limits the range of usable opcodes | |
45 | # on certain CPU subtypes. Try the ISA variant first, and if that fails, | |
46 | # fall back on -Wa,-dsp for the old binutils versions. Even without DSP | |
47 | # opcodes, we always want the best ISA tuning the version of binutils | |
48 | # will provide. | |
