The plugin appears to be loaded by a 2nd process, initialized, and

That's correct.
Hi guys,
I have a test case (shell sort, see attached) compiled with different
ARM compilers:
GCC-4.6.3, GCC-3.4.6, and ARMCC.
Both ARMCC and GCC-3.4.6 generate quite optimal assembly while GCC-4.6.3
inserts extra load/store instructions compared to the other compilers.
Can the SSA representatio
Hi,
This is a case when ivopts pass makes too many induction variables, exceeding
the number of available registers. If you want to debug it, see
ivopts_global_cost_for_size in tree-ssa-loop-ivopts.c and its callers;
perhaps, the issue is that it fails to account for IVs created in inner loops

That much I understand. But it's cc1 that is in two processes, and gcc -v only
shows it being invoked once. Finally the output on stderr is only from one of
the two processes.
Remove the finish type register and suddenly cc1 runs (as expected) and the
logfiles PID and the console PID match once

Ah! I see what might be happening. I was using assert(0) in the
callback to stop the program's execution (to examine the output at
that location). When I do this, I get the funky results.

blackberry (no html e-mail editing). The co

Hi,
In scan_one_insn, gcc checks whether an insn loads a parameter from

What I do not understand is the check condition like below checks the

checking memory

Hello Rick,
Since nobody responded, I'll try. :-)

This is the beta release of binutils 2.22.52.0.2 for Linux, which is
based on binutils 2012 0424 in CVS on sourceware.org plus various
changes. It is purely for Linux.
All relevant patches in patches have been applied to the source tree.
You can take a look at patches/README to see what have been

All subcommands support response files (@foo), which can be used to work
around such a limit.

I had to adjust a couple of files and a test case, but other than
that, no surprises.
Tested on x86_64.
