Akira Hatanaka 55c0268714 Reduce the size of MCRelaxableFragment. ... MCRelaxableFragment previously kept a copy of MCSubtargetInfo and MCInst to enable re-encoding the MCInst later during relaxation. A copy of MCSubtargetInfo (instead of a reference or pointer) was needed because the feature bits could be modified by the parser. This commit replaces the MCSubtargetInfo copy in MCRelaxableFragment with a constant reference to MCSubtargetInfo. The copies of MCSubtargetInfo are kept in MCContext, and the target parsers are now responsible for asking MCContext to provide a copy whenever the feature bits of MCSubtargetInfo have to be toggled. With this patch, I saw a 4% reduction in peak memory usage when I compiled verify-uselistorder.lto.bc using llc. rdar://problem/21736951 Differential Revision: http://reviews.llvm.org/D14346 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@253127 91177308-0d34-0410-b5e6-96231b3b80d8		2015-11-14 06:35:56 +00:00
