llvm dev - Jan 2012 - [LLVMdev] llvm3.0 => build failure under Linux MIPS & MIPSEL

Hello,

In order to have llvm-3.0 into Debian Wheezy, I have to fix a last build
failure under  MIPS & MIPSEL.

The full mipsel build log is available here:
https://buildd.debian.org/status/fetch.php?pkg=llvm-3.0&arch=mipsel&ver=3.0-5&stamp=1324350511
[1]

The error is the following:
/build/buildd-llvm-3.0_3.0-5-mipsel-jV6EnH/llvm-3.0-3.0/build-llvm/Release/bin/llvm-tblgen

Any ideas? I am available for testing.

LLVM 2.9 was building fine [2].

Thanks,

[1] Please note that mips log is available here: 
https://buildd.debian.org/status/fetch.php?pkg=llvm-3.0&arch=mips&ver=3.0-5&stamp=1324342896
but since it is a parallel build, it is pretty boring to read.

What if you provide -O0 to the compiler?

Actually, that wasn't need. 
A rebuild fixed the issue. The error I had was probably due to an issue
in an underlying dependency... 

Sorry about the noise.
