Ran out of registers error in llc

[Danna bib]

Hello all,

I am working with LLVM 3.4. I reserved half of arm registers in order to do
some optimization in backend (after register allocation). It works fine
with several SPEC2006 benchmarks, but in some of them such as gcc and
gobmk, I got the following error.
"LLVM ERROR: ran out of registers during register allocation"
So, my question is how I can solve that problem?

I would appreciate any advise you may have.

regards,
Danna
