diff gen/tollvm.cpp @ 445:cc40db549aea
Changed the handling of variadic intrinsics a bit.
Removed the -fp80 option and made real be 80bit floats on X86, this is what the D spec really says it should be and fixes a bunch of issues.
Changed the handling of parameter attributes to a bit more generalized approach.
Added sext/zext attributes for byte/short/ubyte/ushort parameters, fixes #60 .
Parameter attribs now properly set for intrinsic calls if necessary.
Made the tango.math.Math patch less intrusive.
Fixed/added some mini tests.
