cpp文件调用汇编函数

要注意汇编文件的项类型正确配置

;includelib ucrt.lib
includelib legacy_stdio_definitions.lib

EXTERN printf:proc

.data
szFormat db '%s',0
szHello db 'Hello X64',0

.code
x64_print proc
	sub rsp,28h
	lea rcx, szHello
	call printf
	mov eax,666
	add rsp,28h
	ret
x64_print endp
end

extern "C" int x64_print();

int main()
{
	x64_print();
	return 0;
}
