llvm dev - Jun 2011 - [LLVMdev] Recommended GCC version for ARM/Linux platform for LLVM compilation.

Hello,

I'm trying to find myself, but anyway, I'm curious what's the 
recommended GNU C++ version for LLVM compilation on ARM/Linux platform? 
I'm using various version of Ubuntu and so far the best compiler I found 
was 4.4.1 (Ubuntu 4.4.1-4ubuntu9)[1]. With this and with just -O1 as 
optimize option I've been able to get to 1 failing testcase. Other 
tested were 4.4.3 and 4.5.2 and with default -O3 I'm on about 100 (4.5.2 
being the worst compiler here) of failing testcases (those compilers 
generates thumb by default) and with "-marm -O1" as optimize option
I'm
on 28 (4.5.2) and 18 (4.4.3) failing testcases. (-marm being better than 
-mthumb) (also here[2])

So I'm curious what's *the* recommended compiler on this platform which 
LLVM development is using?

Thanks!
Karel

Hi Karel,

I'm not sure what test cases you're talking about, but we use
CodeSourcery's GCC and binutils (latests, not stable, because of new
core support) and it works a treat.

You can freely download it from their website.

cheers,

Hi Renato,

I'm not sure if this is not misunderstanding. As far as I know, 
CodeSourcery provides cross-compilers for ARM platforms and not native 
compilers. In my case I'm talking about native compiler running on 
Cortex-A9 (PandaBoard) and compiling LLVM directly on PandaBoard...

The test cases I'm talking about are those which are directly packed in 
LLVM (test subdirectory) so you compile LLVM and then just invoke `make 
check' to test the build ...

Thanks,
Karel
