[cfe-dev] building LLVM/Clang on Windows 7 x64 using MinGW/MSYS

Fri Oct 18 13:28:34 PDT 2013

Hi,

Thanks for the patch. It fixed the link error on lli.exe using the 64
bit tools. The build proceeded to the 82% mark and then failed with a
couple of new errors from the assembler.

Does anyone have any ideas about what might be causing the
Registry.cpp.obj file to have too many sections?

There were several warnings and notes generated when compiling
Registry.cpp. The full output from the build step are copied below.
