This generalizes the
abs
handling from #1253 and #1254 to happen at any level of the expression, just like other tmpSpecials. This change is in the first commit.The rest are some refactoring of the surrounding code because the indentation is already 14 tabs deep. I wanted to clean it up more, but the implementation of
__builtin_isgreater
, etc is implemented hackily to convertNot{0}
to1
to1.0
to represent it as the expected value for float domains.
