From: "lh_mouse at 126 dot com" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug target/53929] [meta-bug] -masm=intel with global symbol Date: Thu, 04 May 2023 07:24:12 +0000 [thread overview] Message-ID: <bug-53929-4-Cplyf2mNQL@http.gcc.gnu.org/bugzilla/> (raw) In-Reply-To: <bug-53929-4@http.gcc.gnu.org/bugzilla/> https://gcc.gnu.org/bugzilla/show_bug.cgi?id=53929 --- Comment #17 from LIU Hao <lh_mouse at 126 dot com> --- Yeah. It looks to me like the Microsoft compiler doesn't actually uses the assembler (like LLVM). Given the C source: ``` extern int rax; int main() { return rax; } ``` which compiled without errors: ``` > cl /O2 /c test.c /Fatest.asm Microsoft (R) C/C++ Optimizing Compiler Version 19.29.30148 for x64 Copyright (C) Microsoft Corporation. All rights reserved. test.c ``` and produced this assembly file ``` include listing.inc INCLUDELIB LIBCMT INCLUDELIB OLDNAMES PUBLIC main EXTRN rax:DWORD _TEXT SEGMENT main PROC ; COMDAT mov eax, DWORD PTR rax ret 0 main ENDP _TEXT ENDS END ``` which can't be assembled ``` > ml64 /c test.asm Microsoft (R) Macro Assembler (x64) Version 14.29.30148.0 Copyright (C) Microsoft Corporation. All rights reserved. Assembling: test.asm test.asm(9) : error A2008:syntax error : rax test.asm(16) : error A2032:invalid use of register ```
