From f037f413506af9e32898e102f391175a3a2852ef Mon Sep 17 00:00:00 2001 From: Jay Foad Date: Tue, 4 Nov 2025 12:00:44 +0000 Subject: [IR] Add new function attribute nocreateundeforpoison (#164809) Also add a corresponding intrinsic property that can be used to mark intrinsics that do not introduce poison, for example simple arithmetic intrinsics that propagate poison just like a simple arithmetic instruction. As a smoke test this patch adds the new property to llvm.amdgcn.fmul.legacy. --- llvm/lib/Bitcode/Reader/BitcodeReader.cpp | 2 ++ 1 file changed, 2 insertions(+) (limited to 'llvm/lib/Bitcode/Reader/BitcodeReader.cpp') diff --git a/llvm/lib/Bitcode/Reader/BitcodeReader.cpp b/llvm/lib/Bitcode/Reader/BitcodeReader.cpp index 1bdf3e9f..8930d64 100644 --- a/llvm/lib/Bitcode/Reader/BitcodeReader.cpp +++ b/llvm/lib/Bitcode/Reader/BitcodeReader.cpp @@ -2257,6 +2257,8 @@ static Attribute::AttrKind getAttrFromCode(uint64_t Code) { return Attribute::Captures; case bitc::ATTR_KIND_DEAD_ON_RETURN: return Attribute::DeadOnReturn; + case bitc::ATTR_KIND_NO_CREATE_UNDEF_OR_POISON: + return Attribute::NoCreateUndefOrPoison; } } -- cgit v1.1
