Original message: https://gcc.gnu.org/ml/gcc-patches/2017-07/msg02005.html
Patches 2 and 3 have been committed and I have corrected the error in
patch 5. I configuring with --enable-checking=yes,rtl
--enable-languages=all and retested with
RUNTESTFLAGS="--target_board=unix/\{,-m32\}" The updated patches fix an
error when using mov instead of push and add documentation for changes
to target-supports.exp. I have included modified ChangeLogs.
In addition to to fixing the ICE, this patch set makes more efficient
use of stack space in some cases the outgoing stack boundary is > 16
bytes and realignment is necessary. This adds new tests, some of which
require avx512f (gcc/testsuite/gcc.target/i386/pr80969-4*.c) -- these I
have only tested these using Intel SDE.
Below is an updated list of the patches.
1. https://gcc.gnu.org/ml/gcc-patches/2017-07/msg02006.html
2. Committed.
3. Committed.
