<!--LLVM PR SUMMARY COMMENT--> @llvm/pr-subscribers-clang-codegen Author: Mariya Podchishchaeva (Fznamznon) <details> <summary>Changes</summary> 9ad72df55cb74b29193270c28f6974d2af8e0b71 added split of _BitInt constants when required. Before folding back, check that the constant exists. --- Full diff: https://github.com/llvm/llvm-project/pull/112218.diff 2 Files Affected: - (modified) clang/lib/CodeGen/CGDecl.cpp (+1-1) - (modified) clang/test/CodeGenCXX/ext-int.cpp (+15) ``````````diff diff --git a/clang/lib/CodeGen/CGDecl.cpp b/clang/lib/CodeGen/CGDecl.cpp index 30af9268b30e2e..1d0660292cecc1 100644 --- a/clang/lib/CodeGen/CGDecl.cpp +++ b/clang/lib/CodeGen/CGDecl.cpp @@ -1945,7 +1945,7 @@ void CodeGenFunction::EmitAutoVarInit(const AutoVarEmission &emission) { replaceUndef(CGM, isPattern, constant)); } - if (D.getType()->isBitIntType() && + if (constant && D.getType()->isBitIntType() && CGM.getTypes().typeRequiresSplitIntoByteArray(D.getType())) { // Constants for long _BitInt types are split into individual bytes. // Try to fold these back into an integer constant so it can be stored diff --git a/clang/test/CodeGenCXX/ext-int.cpp b/clang/test/CodeGenCXX/ext-int.cpp index 7758e92d74a05f..a098f5a9057c0e 100644 --- a/clang/test/CodeGenCXX/ext-int.cpp +++ b/clang/test/CodeGenCXX/ext-int.cpp @@ -614,3 +614,18 @@ void TBAATest(_BitInt(sizeof(int) * 8) ExtInt, // NewStructPathTBAA-DAG: ![[EXTINT_TBAA_ROOT]] = !{![[CHAR_TBAA_ROOT]], i64 4, !"_BitInt(32)"} // NewStructPathTBAA-DAG: ![[EXTINT6_TBAA]] = !{![[EXTINT6_TBAA_ROOT:.+]], ![[EXTINT6_TBAA_ROOT]], i64 0, i64 1} // NewStructPathTBAA-DAG: ![[EXTINT6_TBAA_ROOT]] = !{![[CHAR_TBAA_ROOT]], i64 1, !"_BitInt(6)"} + +namespace A { +template <int N> struct S { + using T = _BitInt(N); + T Data; +}; +template <int N> void foo(S<N> B) { + const auto Var = B.Data; +} + +void bar() { + S<2080> a; + foo(a); +} +} `````````` </details> https://github.com/llvm/llvm-project/pull/112218 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
