Thanks Saleem, Nick.
I will try with the latest code and share the results.
Though, just curious if I need to really use clang to generate the object file
and the current steps won't work? I ask because using .c file was only an
illustration. For my project the IR is not generated from .c files or clang.
Thanks,
Daman

Subject: Support for Windows Phone 8.1
Hi LLVMdev,
Does the latest trunk code support Windows Phone 8.1 target ?
I don't know this, but ...
I was trying out a simple program, but Visual Studio 2013’s linker
failed for me with this error - app.obj : error LNK2008: Fixup target is
not aligned ‘add3'
This is what I tried -
* Download latest LLVM sources (as on 4th June) and build them on my
MAC 10.9 machine.
* Wrote a simple a.c, with add3 function-
int add3(int i, int j)
{
int k = i+j;
return k;
}
* Create LLVM IR using Xcode 5.1’s clang ( *clang –S -O0 -emit–llvm a.c* )
* Create obj file – using llc - *. /i686-apple-darwin11-llc
-filetype=obj -mtriple=thumbv7-windows-msvc -O0 a.s *
... in general this doesn't work. The transformation from C to LLVM IR needs
to know the target triple. Try "clang --target=thumbv7-windows-msvc a.c -c
-o a.obj"? Since clang has a built-in assembler, you should get a valid
COFF file out, to the extent that clang and llvm support this target.
If that doesn't work, I may suggest it's unsupported.
As Nick mentioned, please generate the object file directly from clang. You can
use armv7-windows or thumbv7-windows (clang will translate armv7-windows to
thumbv7-windows implicitly). I just fixed a bug that should allow you to link
the object files with link.
Nick
* Now on a Windows 8.1 Desktop machine, link this object file into
sample (new DirectX app, windows phone) Visual Studio 2013 project.
* Declare and Call add3 in the sample windows project.
* I then get a linker error on building the solution.
*1>app.obj : error LNK2008: Fixup target is not aligned 'add3'*
*1>LINK : fatal error LNK1165: link failed because of fixup errors*
*========== Rebuild All: 0 succeeded, 1 failed, 0 skipped ==========*
Could someone please confirm about the state of support for Windows
Phone 8.1 ? Or am I missing something here?
Thanks,
Daman
