I tried building LDC2 on windows according to http://wiki.dlang.org/Building_and_hacking_LDC_on_Windows_using_MSVC, but failed while building phobos-ldc.vcxproj.

The error is:
...
...
Generating std/file.obj
 Unknown frame setup opcode!
 UNREACHABLE executed at D:\ldcenv\llvm\lib\Target\X86\X86MCInstLower.cpp:707!
 Stack dump:
0.        Running pass 'X86 Assembly / Object Emitter' on function '@_D3std4file6getcwdFZAya'

A minor issue about those instructions in the url is, both "git checkout -b ldc" in section "Build LDC2" failed as ldc branch already exists, just removing -b option works for me.

Another instruction confuse me is that, -DLLVM_TARGETS_TO_BUILD="X86" option to cmake while generating Win64 project files, is X86 instead of X64 here correct?

Hi Zhouxuan,

I noticed that, too. It comes from my patch for EH handling. Something has changed in LLVM and I did not correct the patch yet. (I correct it as soon as I understand the LLVM changes causing the failure.)

It works if you do not apply the patch. But then you get no exception handling...

Kai

Hi Zhouxuan!

Indeed, this section can be simplified. I am going to update the instructions.

Yes, X86 is right. It includes the 32bit and 64bit targets for Intel/AMD.

There is also PowerPC for 32bit and 64bit PowerPC targets. But is no general rule: target ARM is for ARMv7 (32bit) and target AArch64 is for ARMv8 (64bit).

Instructions are updated now.

The root cause of this problem is PR16779 (http://llvm.org/bugs/show_bug.cgi?id=16779). I try to fis this.

Hey Kai

I noticed that, too.
Would you send me the llvm SRC files which can be used with
a win64eh_all_20131021.diff file.

Thanks you.

Hi tae,

I have updated the patch in the wiki. Just use the new version.
