Subject: [Bug c/99872] [11 Regression] optimizations sometimes lead to missing asm prefixes
Date: Tue, 06 Apr 2021 08:27:54 +0000	[thread overview]
Message-ID: <bug-99872-4-8ZSJNRJNZY@http.gcc.gnu.org/bugzilla/> (raw)

--- Comment #2 from jyong at gcc dot gnu.org ---
No, its the internal compiler symbols like LC5 and _LC6 generated by GCC
ignoring the underscore prefix setting for the target, causing GAS to emit them
as external undefined symbols. LD fails to find the symbols to satisfy them
upon linking.

32bit Windows PE symbols should come with an underscore prefix, this does not
apply to 64bit Windows code.
