[PATCH] D15138: Disable signbit related bitcast optimization for illegal types (e.g ppc_fp128)

[hfinkel@anl.gov via llvm-commits]

hfinkel added a comment.

Is the code generation for ppc_fp128 better this way? If not, please actually fix the problem. If so: 1) please specifically test (in the regression test) for the better code generation and 2) make the change specific to ppc_fp128 [doing this for all illegal types is not good because on soft-float implementations this is still useful even though the types are illegal].
