------------------------------------------------------------------------ r195491 | probinson | 2013-11-22 11:11:24 -0800 (Fri, 22 Nov 2013) | 11 lines Teach ISel not to optimize 'optnone' functions (revised). Improvements over r195317: - Set/restore EnableFastISel flag instead of just running FastISel within SelectAllBasicBlocks; the flag is checked in various places, and FastISel won't run properly if those places don't do the right thing. - Test looks for normal ISel versus FastISel behavior, and not something more subtle that doesn't work everywhere. Based on work by Andrea Di Biagio. ------------------------------------------------------------------------ git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_34@195604 91177308-0d34-0410-b5e6-96231b3b80d8
