Yeah, GCC 13 is branching out, so we need to wait for GCC 14, I also
really want to have this in GCC 13 too, and I am a little concerned
that it is still not officially ratified yet for merge that.

Hi,
This patch xfails a float128 comparison test case on powerpc64
that fails due to a longstanding issue with floating-point
compares.
See https://gcc.gnu.org/bugzilla/show_bug.cgi?id=58684 for more
information.
The patch passed regression test on Power Linux platforms.
Thanks

Hi,
This patch adds ppc_cpu_supports_hw into explicit name checking in
proc is-effective-target-keyword. So ppc_cpu_supports_hw can be used
as a target selector in test directives. It's required by patch2 of
this issue.
Thanks

This small patch just changes around the code slightly to
make it easier to understand that the cases were handling diamond
shaped BB for both do_store_elim/do_hoist_loads.
There is no effect on code output at all since all of the checks
are the same still.
Note this depends on
https://gcc.gnu.org
After optimization for RA, memory op is not propagated into
instructions(>1), and it make testcases not generate vxorps since
the memory is loaded into the dest, and the dest is never unused now.
So rewrite testcases to make the codegen more stable.

For diamond bb phi node detection, there is a check
to make sure bb1 is not empty. But in the case where
bb1 is empty except for a predicate, empty_block_p
will still return true but the minmax code handles
that case already so there is no reason to check
if the basic block is empty.

This patch compresses them together with a couple of code iterators.
No functional change intended.

Could you add more description? maybe like this:

The following makes sure to remove the copy edges we ignore or
need to special-case only once.
Bootstrapped and tested on x86_64-unknown-linux-gnu, pushed.
* tree-ssa-structalias.cc (solve_graph): Remove self-copy
edges, remove edges from escaped after special-casing them.

The following fixes the escape special casing to test the proper
variable IDs.

Since we do not update successor edges when merging nodes we have
to deal with this in the users. The following avoids putting those

The following removes a special case to not merge a block with
only a non-local label. We have a restriction of non-local labels
to be the first statement (and label) in a block, but otherwise nothing,
if the last stmt of A is a non-local label then it will be still
the first statement of the comb
Update the Patch v2 for more detail information for clarification. Please help
to review continuously.

The following adjusts those.
