Extended Description

Hello
I try to compile the open source project zorba (http://www.zorba-xquery.com/) with clang on Windows. Unfortunately, I came across an internal clang error I am not able to fix myself:

EmitRawText called on an MCStreamer that doesn't support it, something must not be fully mc'ized

Do you know that problem? Is it fixable? Or by-passable?

Try passing -no-integrated-as as a workaround.

Chris, your solution bypasses the problem. Although I get warnings like crazy now:

Should mark the Bug as resolved or do you wanna keep it to fix the real cause of the error?

What program is emitting those errors? They look like llvm-mc, but -no-integrated-as should be using the system as tool...

I'm also confused as to which C++ headers you are using.

[llvmbot]

I am using the Visual Studio headers. I set up my build directory with the following command:

set CC=C:...\clang.exe
set CXX=C:...\clang++.exe

cmake -G "NMake Makefiles" ..\trunk

If it helps, this is the clang++ command that prints prints the warnings:

C:\Users\sausalito\Desktop\zorba-devel\clang\build\bin\clang++.exe -no-integrated-as -g -IC:\Users\sausalito\Desktop\thirdparty\libxml2-2.7.7.win32\include -IC:\Users\sausalito\Desktop\thirdparty\curl\curl-7.21.1\include -IC:\Users\sausalito\Desktop\thirdparty\tidy-060405-dll\include -IC:\Users\sausalito\Desktop\thirdparty\iconv-1.9.2.win32\include -IC:\Users\sausalito\Desktop\thirdparty\icu4c-4_4_1-src\icu\include -IC:\Users\sausalito\Desktop\thirdparty\xerces-c-3.1.1\src -IC:\Users\sausalito\Desktop\zorba-devel\build_clang\include -IC:\Users\sausalito\Desktop\zorba-devel\trunk\include -IC:\Users\sausalito\Desktop\zorba-devel\trunk\external -o CMakeFiles\json.dir\errstrings.obj -c C:\Users\sausalito\Desktop\zorba-devel\trunk\external\json\errstrings.cpp

Oh, C++ is very broken when targeting Microsoft Windows. I'm surprised it even tried to generate code when using the MSVC headers.

-no-integrated-as is using llvm-mc because MSVC doesn't have an assembler that can assemble C++ code.

Does the compiled code actually work?

The COFF backend doesn't currently support debug info, so that's probably why it's complaining in this case. I can take a look if you can give me the preprocessed source.

[llvmbot]

Actually, I am not able to compile working code on Windows. Because I compiled clang with visual studio, I assumed that it will work. Therefore, I started immediately compiling my project. But, I am not even able to compile a hello world program. It ends with the following error msg:

You have to either use MinGW, or use only C. We are working to get MSVC C++ headers working.

[llvmbot]

Ok. Then, I need to wait till MSVC C++ headers are working because our project depends on several other MSVC projects. Can you give me a rough time estimate? When will the MSVC C++ headers work?

repro case

[llvmbot]

(Oops, the comment was lost with the repro case I just attached. Try 2...)

I'm also seeing this error message on Windows when generating object files from bitcode emitted by my own compiler (i.e. clang isn't involved at all). It only seems to happen when debugging metadata is included in the output. (I realize that debugging info isn't supported on Windows currently, so this error isn't a huge issue for me.)

I've attached a test case. (Unfortunately bugpoint was being fiddly for me and I couldn't get it to generate a minimal reproducer.)

[rnk]

This appears to have been fixed. 'llc -filetype=obj simple.ll' works for me on Windows.
