Phoronix: Clang-Cl Tries To Imitate Visual Studio's Compiler

Clang-Cl is one of the new driver modes to the Clang C/C++ front-end compiler to LLVM and its designed to imitate Visual Studio's cl.exe compiler...

Will this be able to build MSVC style inline assembly?

Huh?
As far as I know, VC >= 2K5 no longer supports in-line assembly in any form - forcing you to use .asm files instead.

I don't really know, as MSVC isn't my main IDE at all. I just want to be able to build a project that uses it without having to reboot to Windows, to add some modifications. As GCC is unable to build this kind of assembly, cross compiling with MinGW fails.

Same question but with Visual Studio's built-in support for OLE/COM inside C++

(just "import" something and you get access to the object as a regular C++ class, without needing to fumble around with implement compiler, etc.)

I ended up using DispHelper back then, but I was curious if these days a solution more closely similar to Visual C++ exists.

This only implements command line arguments used by cl.exe. Nothing more.

GCC does support inline assembly, it just uses a different type of inline assembly. E.g.

In GCC:

__asm__ volatile
(
"incq %0 ;"
: "=m" (*value)
:
);

In old(er) version of MSVC:

__asm
{
mov eax, dword ptr [value]
inc dword ptr [eax]
}

As I said, Microsoft dropped support for inline assembly in newer versions of VC.

I'm fully aware, that's why I asked for "MSVC style inline assembly".

Sorry. My mistake, didn't notice it.

No prob. Anyway, if you say the new versions of MSVC doesn't support it, I might be able to convince the rest of the crew working on that program (who uses MSVC) to put assembly calls in .s or .asm files, and then I can use a trick I've read about to include it as inline in GCC.
