Yes, my assembly files do use prefix macro (ASM_PFX) for wrapping the underscore. We use the __USER_LABEL_PREFIX__ to control the prefix macro expand to be "_" as below. I find the __USER_LABEL_PREFIX__ has been predefined by clang-cl, but it is defined as nothing. That is why my prefix macro expands to be nothing. Do you know why the clang-cl predefines the __USER_LABEL_PREFIX__ as nothing? #ifndef...

Hi Rui, Peter, You know I'm enabling the "clang-cl + lld-link" toolchain for Uefi firmware. I meet a problem that the lld-link fails to link 32bits assembly functions, but can link 64bits assembly functions successfully. I need your suggestion. Below is an example to show my problem in linux. The example has two only source files: main.c and foo.nasm. $ cat main.c void Foo (void);

In .S files you can use any of the C predefined macros, in particular, __USER_LABEL_PREFIX__ might be what you want. Cheers, Rafael

Hello, Nathan > or if it should be a configure test, which might be safer. Are there > any x86 platforms (other than apple) that don't need PLT-indirect calls? Yes, mingw. However just tweaking the define is not enough - we're not loading address of GOT into ebx before the call (on 32 bit ABIs) thus the call will be to nowhere. -- With best regards, Anton Korobeynikov Faculty of

Hi all, I've encountered a couple of minor build issues on Solaris that have crept in since 2.5, fixes below: 1. In lib/Target/X86/X86JITInfo.cpp, there is: // Check if building with -fPIC #if defined(__PIC__) && __PIC__ && defined(__linux__) #define ASMCALLSUFFIX "@PLT" #else #define ASMCALLSUFFIX #endif Which causes a link failure due to the non-PLT
