[LLVMdev] Problem cross-compiling llvm-gcc for AIX-PowerPC

[Patrick Simmons]

  Compiling llvm-gcc on an x86 machine with 
--target=powerpc-ibm-aix5.1.0.0, I get the following error:

make \

Is there anything else I should be doing to build a cross-compiler to 
generate LLVM bitcode for AIX?  My ultimate goal here is just to get a 
compiler which can generate llvm bitcode I can manipulate and then run 
through the C backend to generate source I can then compile on AIX.  
Unfortunately, I must run the code on AIX on POWER.  How should I best 
approach this problem?
