This seems to work now:
$ cat test.c
void __stdcall StdcallFunc() {};
void Test()
{
asm ("call _StdcallFunc at 0\n");
}
$ out/gn/bin/clang-cl -fuse-ld=lld test.c -m32 /LD /link /nodefaultlib /noentry
$ out/gn/bin/llvm-objdump --disassemble test.dll
test.dll: file format COFF-i386
Disassembly of section .text:
10001000 .text:
10001000: 55 pushl %ebp
