URL: https://github.com/llvm/llvm-project/commit/a333071754ba2cf71ce11633def9657bd28d65a7 DIFF: https://github.com/llvm/llvm-project/commit/a333071754ba2cf71ce11633def9657bd28d65a7.diff LOG: [X86] Remove DecodeVPERMVMask and DecodeVPERMV3Mask This patch removes the variants of DecodeVPERMVMask and DecodeVPERMV3Mask that take "const Constant *C" as they are not used anymore. They were introduced on Sep 8, 2015 in commit e88038f23517ffc741acfd307ff92e2b1af136d8. The last use of DecodeVPERMVMask(const Constant *C, ...) was removed on Feb 7, 2016 in commit 73fc26b44a8591b15f13eaffef17e67161c69388. The last use of DecodeVPERMV3Mask(const Constant *C, ...) was removed on May 28, 2018 in commit dcfcfdb0d166fff8388bdd2edc5a2948054c9da1.
