Using the builtin failed on 32-bit architectures: | clang/lib/AST/ExprConstant.cpp:14299: [..]: Assertion `I.getBitWidth() == Info.Ctx.getIntWidth(E->getType()) && "Invalid evaluation result."' failed. The return type is meant to be size_t. Fix it. >From 406428ff864522c8200710956c81c74a0055259a Mon Sep 17 00:00:00 2001 From: Marco Elver <[email protected]> Date: Wed, 19 Nov 2025 21:51:52 +0100 Subject: [PATCH] [Clang][Sema] Fix __builtin_infer_alloc_token() return type Using the builtin failed on 32-bit architectures: | clang/lib/AST/ExprConstant.cpp:14299: [..]: Assertion `I.getBitWidth() == Info.Ctx.getIntWidth(E->getType()) && "Invalid evaluation result."' failed.
