Hi Iain,
Thanks for reviewing. I’m happy to make the suggested changes. One comment

The problem here is __builtin_shuffle when called with two arguments
instead of 1, uses a SAVE_EXPR to put in for the 1st and 2nd operand
of VEC_PERM_EXPR and when we go and gimplify the SAVE_EXPR, the type
is now error_mark_node and that fails hard.
This fixes the problem by
v2: https://gcc.gnu.org/pipermail/gcc-patches/2021-September/579976.html
Changes in v3:
* Do not propagate bias along tcc_references.
* Call get_rank () before checking biased_names.
* Add loop-carried phis to biased_names.
* Move the propagate_bias_p () call outside of the loop.
* Test with -ftree
Biasing loop-carried PHIs during the 1st reassociation pass interferes
with reduction chains and does not bring measurable benefits, so do it
only during the 2nd reassociation pass.
gcc/ChangeLog:
* passes.def (pass_reassoc): Rename parameter to early_p.
* tree-ssa-reassoc
PR tree-optimization/49749 introduced code that shortens dependency
chains containing loop accumulators by placing them last on operand
lists of associative operations.
456.hmmer benchmark on s390 could benefit from this, however, the code
that needs it modifies loop accumulator before using it, a

Hi all,
This is somewhat a continuation of the previous effort [1] to bring nanoMIPS
support upstream.
We would like to move our toolchain releases [2] to something more closer to
the upstream GCC.
As part of that, we are interested in feedback from the community if the
current approach of

Firstly, the option handling was building suggestions without checking
if an option is disabled. This could have caused other unhelpful

Secondly, the key issue here appears to be the lack of CL_JOINED flag

This patch is prototype proof-of-concept (and request for feedback)
that touches the front-end, middle-end and backend. My recent patch to
perform RTL constant folding of saturating arithmetic revealed how
difficult it is to generate a (portable) test case for that functionality.

Hi Jason,
1. Thank you very much for your detailed comments for my patch and I really
appreciate it! Here is my revised patch:
The root cause of this bug is that it considers reference with
cv-qualifiers as an error by generating value for variable "bad_quals".
However, this is not correct for c

I just found out that clang actually correctly reject this code during
specialization.

Fix protocol list layout for non-LP64. clang and objc4 both give the `count`
field as `long`, not `intptr_t`. Those are the same on LP64, but not
everywhere. For non-LP64, this fixes binary compatibility with clang-built
classes.
This was more complicated than I anticipated, because the rele
