It would be nice to not have these explicitly listed. But at the very least, I think that having a list and looping through it would be better:
for (const auto Feature : {"vfpv2", "vfpv3", "vfpv4", "fp-armv8", "fullfp16"})
if (std::find(std::begin(Features), std::end(Features), "+" + Feature) == std::end(Features))
continue;
else
Features.push_back("-" + Feature);
================
Comment at: lib/Driver/ToolChains/Arch/ARM.cpp:429
+ if (HasDotProd)
+ Features.push_back("-dotprod");
}
----------------
Similar.
