Also added the testcase that should have been in r215194.
This behaviour has surprised me a few times now. The problem is that the
generated MipsSubtarget::ParseSubtargetFeatures() contains code like this:
if ((Bits & Mips::FeatureABICalls) != 0) IsABICalls = true;
so '-abicalls' means 'leave it at the default' and '+abicalls' means 'set it to
true'. In this case, (and the similar -modd-spreg case) I'd like the code to be
IsABICalls = (Bits & Mips::FeatureABICalls) != 0;
or possibly:
if ((Bits & Mips::FeatureABICalls) != 0)
IsABICalls = true;
else
IsABICalls = false;
and preferably arrange for 'Bits & Mips::FeatureABICalls' to be true by default
(on some triples).
