`asm()` on function declarations is used for specifying the mangling. But that specific spelling is a GNU extension unlike `__asm()`. Found by building with `-std=c2y` in Clang's C frontend's config file. >From 0b1ddafc613447427e12f0d4784c1ee688b5640a Mon Sep 17 00:00:00 2001 From: Raul Tambre <[email protected]> Date: Thu, 6 Nov 2025 14:45:27 +0200 Subject: [PATCH] [NFCI][lldb][test] Avoid unnecessary GNU extension for assembly call `asm()` on function declarations is used for specifying the mangling.
