[cfe-dev] Cilk Plus extensions in LLVM/Clang

[Pan, Wei]

Hi Hal,

This patch could allow you to compile and run the fib program on PPC! 

Have you tried to compile the runtime on PPC? If you get it compiled (with possible fixes or hacks), then clang should be ready for compiling your fib program for PPC. Since there is no exception and floating point computations in fib, you could disable exceptions and the inline asm for saving floating point states (clang/lib/CodeGen/CGCilkPlusRuntime.cpp). 

Thanks!

Wei

It seems from this guide that the first task is to make sure that __builtin_{setjmp/longjmp} work on the target platform. In r177666, I committed an implementation for PowerPC (inspired by the X86 implementation). You can now update your wiki ;)

Thanks again,
Hal
