Re: [PATCH ARM]Print CPU tuning information as comment in assembler file.
Ping.
This is for case failures and it doesn't affect normal compilation, so
I suppose it's fine for this stage?
Thanks,

Hi,
This patch is the first part fixing memset-inline-{4,5,6,8,9}.c failures on
cortex-a9. GCC/arm doesn't generate any tuning information in assembly, it
can't tell whether we are compiling for cortex-a9 tune if the compiler is
configured so by default.
This patch introduces a new (target dependent) option -mprint-tune-info.
It prints CPU tuning information as comment in assembler file, thus DEJAGNU
can check it and make decisions. By default the option is disabled, so it
won't change current behaviors. For now, pointers in tune structure are not
printed, we should improve that and output more useful information in the
long run.
Another patch is followed adding DEJAGNU test function and adapting test
strings.
Build and test on arm-none-eabi, is it OK?
