Some Windows bots using MSVC 2019 and 2022 get assertion errors in the clang-doc lit tests (see [here](https://github.com/llvm/llvm-project/pull/198066). This seems to be due to MSVC having trouble with a correctly initializing structures using std::initializer_list when embedded in a struct declared with constexpr. This workaround changes constexpr to const in a struct definition to avoid this issue. >From 90d2bc8c71e69c65ce4e041b55dc3e7e266b9ade Mon Sep 17 00:00:00 2001 From: wpieb <[email protected]> Date: Fri, 22 May 2026 19:14:15 -0700 Subject: [PATCH] Avoid combining constexpr with std::initializer_list as this seems give MSVC trouble. --- clang-tools-extra/clang-doc/BitcodeWriter.cpp | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/clang-tools-extra/clang-doc/BitcodeWriter.cpp b/clang-tools-extra/clang-doc/BitcodeWriter.cpp index f8431a44ec533..2ab1bbf4a8a16 100644 --- a/clang-tools-extra/clang-doc/BitcodeWriter.cpp +++ b/clang-tools-extra/clang-doc/BitcodeWriter.cpp @@ -252,7 +252,7 @@ struct BlockToIdList { std::initializer_list<RecordId> RIDs; }; -static constexpr BlockToIdList RecordsByBlock[] = { +static const BlockToIdList RecordsByBlock[] = { // Version Block {BI_VERSION_BLOCK_ID, {VERSION}}, // Comment Block _______________________________________________ cfe-commits mailing list [email protected] https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
