This patch adds detection of average instructions:
a = (((wide) b + (wide) c) >> 1);
--> a = (wide) .AVG_FLOOR (b, c);
a = (((wide) b + (wide) c + 1) >> 1);

in cases where users of "a" need only the low half of the result,
making the cast to (
This patch adds AArch64 patterns for the new AVG_FLOOR/CEIL operations.
AVG_FLOOR is [SU]HADD and AVG_CEIL is [SU]RHADD.

Hi all,
This patch adds support for the Arm Cortex-A76 processor in changes.html for
GCC 9.
It enables the AArch64 section of the page and adds the news blob there.
It also adds an entry to the already-existing arm entry.
Ok to commit to CVS (for the aarch64 parts)?
Thanks,

Hi all,
In this testcase the user forces an odd register as the starting reg for a
DFmode value.
The output_move_double function tries to store that using an STRD instruction.
But for TARGET_ARM the starting register of an STRD must be an even one.
This is always the case with compiler-allocated
The patch fixes PR86321 without regression.

Attached are some cleanups to the VRP code dealing with PLUS/MINUS_EXPR

implementation in the future, but is completely independent from any

So this patch converts the v850 port to use LRA. From a code generation
standpoint it looks like the old bare v850 gets slightly worse code.
However, we get slightly better code in general on the newer parts like
v850e3v5.
The only really interesting part of the conversion is the removal of
