Every base 10 digit will take use ~3.32 bits to represent. So for
a 64bit signed integer, it is 20 characters. The buffer was only
20 so it did not fit; add in the null character and "-O" part,
the buffer would be 3 bytes too small.

Ah, yes - those test results should have only been changed for little endian.

Hi Christophe,
Sorry about that, the ICEs should be fixed now and the execution tests are
being fixed now.
They were being hidden by a model bug which kept saying everything passed even
when failed ☹

This is a followup to Srinath's recent patch: the newly added test is
failing e.g. on arm-linux-gnueabihf without R/M profile multilibs.
It is also failing on arm-eabi with R/M profile multilibs if the
execution engine does not support v8.1-M instructions.
The patch avoids this by adding check_e
Hi,
A recent change "gcc: Add vec_select -> subreg RTL simplification"
updated the expected test results for SVE extraction tests. The new
result should only have been changed for little endian. This patch
restores the old expected result for big endian.
Ok for master?
Thanks,
Jonathan

The following defaults --param vect-partial-vector-usage to zero
for x86_64 matching existing behavior where support for this
is not present.
OK for trunk?

Hi Jason,
A new revision of the patch is attached. I think I implemented all your
suggestions.
Please comment on cp/decl2.c (is_alias_template_p). I find it surprising that
I had to write this function. Maybe I missed something? In any case,
DECL_ALIAS_TEMPLATE_P requires a template_decl and t
There are 4 exact copies of the non-null range adjusting code in the
ranger. This patch abstracts the functionality into a separate method.
As a follow-up I would like to remove the varying_p check, since I have
seen incoming ranges such as [0, 0xffef] which are not varying, but
are not-null.
