Re: Second GCC 4.6.0 release candidate is now available


Hi Michael,

Thanks for running these. I spent some time this morning looking
through the results, they largely look ok though I don't have much
perspective on the
the objc/ obj-c++ failures.

These failures here

For v7-a , A9 and Neon - these failures below:

are caused by a broken assembler. All these tests appear to pass
fine in a cross environment on my machine.

These all appear to fail because of the assembler failing to
assemble something like vmov.i64 d9,#-4294967296 which is
vmov.i64 d9,0xffffffff00000000 and a valid instruction.

I think your assembler needs an update

Otherwise the testresults for A9 appear to be largely in line
with other results.

From v5t.

The c90 testfails in your v5t run appear to be some kind of NFS glitch
because the compiler fails to spawn from dejagnu. I tried logging into
ursa2 and tried out the same test after fettling with paths etc and it
just seemed to work.

I'm still looking through the other results but I haven't spotted
anything obvious broken yet.


cheers
Ramana
