New Revision: 157545
URL: http://llvm.org/viewvc/llvm-project?rev=157545&view=rev
Log:
Reimplement the intrinsic verifier to use the same table as Intrinsic::getDefinition,
making it stronger and more sane.
Delete the code from tblgen that produced the old code.
Besides being a path forward in intrinsic sanity, this also eliminates a bunch of
machine generated code that was compiled into Function.o
