Subject: CodeGen: replace use of @llvm.arm.sevl with @llvm.arm.hint
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=653f5c673baa5288e285b5be30aacaf1f70d7d5b;p=clang

CodeGen: replace use of @llvm.arm.sevl with @llvm.arm.hint

Use the new generic @llvm.arm.hint hint intrinsic rather than the specialised
@llvm.arm.sevl hint instruction.
