Hello,
I was trying to extract out the IR for some CELLBE code. However i
was not able to compile with llvm-gcc.
Has someone who has tried this shed some light on the changes required
to use llvm-gcc instead of gcc or xlc.
A simple replacement of gcc with llvm-gcc -emit-llvm -S or marking $CC
as llvm-gcc in the makefile did not work for me. I am using the
standard makefile format supplied with the example codes of CellSDK.
Is there any alternate way / intrinsic which can be called to
introduce calls to the Cell C intrinsic functions??
TIA,
regards,
Kshitiz

Hi Kshitiz, unfortunately it is not possible to build an spu-llvm-gcc yet, there is a small number of issues (mainly support for integer divides and some 128-bit related stuff) which prevent the LLVM SPU backend from compiling libgcc successfully (the low level runtime library which is built as part of llvm-gcc) and thus prevent a successful llvm-gcc build. Please note that the Cell SPU backend is considered experimental. Patches welcome though! :) Greetings, Tilmann On Thu, May 7, 2009 at 6:03 PM, Kshitiz Garg <ksh.cseiitk at gmail.com> wrote:> Hello, > I was trying to extract out the IR for some CELLBE code.
