llvm dev - Dec 2009 - [LLVMdev] cross compiling for Sparc

Hi all,

I am trying to build a cross compiler for Sparc on x386 host. I tried to run
configure with

           configure --enable-targets=sparc
 or with

           configure --target=sparc

but in both cases I got llvm compiler for x86 target. Is there a way to
build a cross compiler
for Sparc (or ARM)?

Thanks.

Hi Fima,

If you're building llvmCore, then it builds a compiler for all targets  
by default. The target is selected at runtime. You can use -mtriple, - 
march and such as options to llc to control which target to emit code  
for.

e.g., to produce an ARM assembly file from a foo.bc bitcode file:
llc -march=arm foo.bc

If you haven't read it already, http://llvm.org/docs/ 
GettingStarted.html has good information which should help. Likewise,  
if you're building the llvm-gcc front end as well as the llvmCore back- 
end, http://llvm.org/docs/GCCFEBuildInstrs.html should help get you  
moving in the right direction.

Regards,
   Jim
