[LLVMdev] Using non-system compiler to build llvm and llvm-gcc front end

[Duncan Sands]

Hi,

this is indeed a miscompilation by your system compiler.  However so many
compilers miscompiled this that a workaround was committed to svn.  So you
may want to check out llvm and llvm-gcc from svn.  Alternatively, maybe
the patch applies to llvm 2.5 too.  I've attached it.


Ciao,

Duncan.
