URL: https://github.com/llvm/llvm-project/commit/8c2ad9e85f677546021880dc88e24f633ccacd93 DIFF: https://github.com/llvm/llvm-project/commit/8c2ad9e85f677546021880dc88e24f633ccacd93.diff LOG: [VE] Correct VMP allocation in calling conv VE used to allocate VM1, VM2, VMP2 (VM4+VM5), and VM3. This patch corrects to allocate VM1, VM2, VMP2 (VM4+VM5), and VM6. Also add a regression test.
