Duncan P. N. Exon Smith	d56771ab94	MC: Constify MCSubtargetInfo in getDeprecationInfo(), NFC ... There's no reason to be able to mutate `MCSubtargetInfo` in `getDeprecationInfo()`. Constify the reference. llvm-svn: 241693	2015-07-08 17:30:55 +00:00
Michael Kuperstein	9b9d97f26a	Use std::bitset for SubtargetFeatures. ... Previously, subtarget features were a bitfield with the underlying type being uint64_t. Since several targets (X86 and ARM, in particular) have hit or were very close to hitting this bound, switching the features to use a bitset. No functional change. The first several times this was committed (e.g. r229831, r233055), it caused several buildbot failures. Apparently the reason for most failures was both clang and gcc's inability to deal with large numbers (> 10K) of bitset constructor calls in tablegen-generated initializers of instruction info tables. This should now be fixed. llvm-svn: 238192	2015-05-26 10:47:10 +00:00
Pete Cooper	8d13c88def	Remove 3 includes from MCInstrDesc.h and explicitly include them where needed ... llvm-svn: 237481	2015-05-15 21:58:42 +00:00
Pete Cooper	2ad0d485cc	Move some methods to a new MCInstrDesc.cpp file to allow includes to be trimmed. NFC. ... MCInstrDesc.h includes things like MCInst.h which i can now remove after this. That will be a future commit. Reviewed by Jim Grosbach. llvm-svn: 237478	2015-05-15 21:29:43 +00:00
