Hi Paul,
Please find attached what I believe is the final version of the patch.
This is looking very good, this does work as advertised and has
all the corner cases coverd.
I also regtested this on powerpc64-unknown-linux-gnu.
I took the opportunity of the delay, while the bounds issue was

Hi Paul,
The patch is OK by me.
Thanks for the review. Committed as rev. 250085.
Thanks for working on speeding up these library functions. Does the
octave version, mentioned in the clf thread, translate easily into C?
I had to remind myself of how octave cell arrays function. It is
certain

Hi,
Currently dg-cmp-results fails to compare fails in Asan tests because
their output includes failing process id:
NA->FAIL: c-c++-common/asan/bitfield-1.c -O0 output pattern test,
is ==18161==ERROR
FAIL->NA: c-c++-common/asan/bitfield-1.c -O0 output pattern test,

Hi,
Currently mklog will fail to analyze lines like this in patches:
diff -rupN gcc/gcc/testsuite/lib/profopt.exp
gcc-compare-checks/gcc/testsuite/lib/profopt.exp
(it fails with "Error: failed to parse diff for ... and ...").
This patch fixes it. Ok for trunk?

Hi,
This patch fixes AutoFDO Dejagnu tests to print relative filenames
instead of absolute ones when AutoFDO is unsupported. This is to
prevent spurious differences in dg-cmp-results.sh, like this:
NA->UNSUPPORTED:

Hi Thomas, Hi All,
Please find attached what I believe is the final version of the patch.
The problem concerning temporaries being generated in lieu of the
descriptor being passed directly - see pointer_array_7.f90 and the

Hi Thomas,

I had to remind myself of how octave cell arrays function. It is
