In any case this should be independent of switches to the test the register allocator. Testing switches should use cl::opts while proper ABI stuff should indeed use subtarget features. http://reviews.llvm.org/D11319 _______________________________________________ cfe-commits mailing list [email protected] http://lists.cs.uiuc.edu/mailman/listinfo/cfe-commits
