[LLVMdev] llvm-gcc-4.0 compilation erros

[Ryan M. Lefever]

Chris,

I'm a little confused.  I am experiencing a crash when compiling the 
llvm-gcc frontend.  According to the bugpoint documentation, bugpoint is 
used to debug "optimizer crashes, miscompilations by optimizers, or bad 
native code generation," which seems like it implies that the frontend 
compiles.  Also, the http://llvm.org/docs/HowToSubmitABug.html 
documentation seems to only address bugs that occur once the frontend is 
compiled.  So, I'm a little unclear what I should submit when filing the 
bug.  If I'm missing something or incorrect, please correct me.

Ryan
