[llvm-commits] [PATCH] AsmWriterEmitter: increase the number of bits for OpcodeInfo from 32-bit to 48-bit to reduce code size

[Manman Ren]

TableGen: increase the number of bits for OpcodeInfo from 32-bit to 48-bit if
necessary, in order to reduce the generated code size by AsmWriterEmitter.

We have 900 cases not covered by OpcodeInfo in ATT AsmWriter and more in Intel
AsmWriter and ARM AsmWriter.

This patch reduced the clang Release build size by 50k, running on a Mac Pro.

Thanks for your feedback.
