It seems like for BUILD_SHARED builds of the toolchain on Windows, specifically aarch64-windows-gnu hosts, the use of the `thread_local` variables in Representation.cpp causes an issue at link time due to non-explicit export. Instead, just wrap them in an accessor function, which should solve the issue in a cross platform way. Fixes #200915 >From 56a553b1c5831d2cf892407c44b078f275764eff Mon Sep 17 00:00:00 2001 From: Paul Kirth <[email protected]> Date: Wed, 3 Jun 2026 08:39:26 -0700 Subject: [PATCH] [clang-doc] Wrap per thread arenas in an accessor for BUILD_SHARED It seems like for BUILD_SHARED builds of the toolchain on Windows, specifically aarch64-windows-gnu hosts, the use of the `thread_local` variables in Representation.cpp causes an issue at link time due to non-explicit export.
