Summary: It's rare but a small number of patterns use IntInit's at the root of the match. On X86, one such rule is enabled by the OptForSize predicate and causes the compiler to use the smaller: %0 = MOV32r1 instead of the usual: %0 = MOV32ri 1 This patch adds support for matching IntInit's at the root and uses this as a test case for the optsize attribute that was implemented in r301750 Reviewers: qcolombet, ab, t.p.northover, rovka, kristof.beyls, aditya_nandakumar Reviewed By: qcolombet Subscribers: igorb, llvm-commits Differential Revision: https://reviews.llvm.org/D32791 llvm-svn: 303678
