--- Comment #3 from Hans-Peter Nilsson ---
In https://gcc.gnu.org/pipermail/gcc-patches/2020-May/545452.html I mentioned a
performance-regression with coremark, from 5227456 cycles (with cc0) to 5238564
(CC_REG), which is about 0.21%.
Not that anyone would notice, except a few maintainers of
targets with delay-slots, and only if the first patch causes
fallout, as the others only touch stuff related to the CRIS target.
The 23 commits have been posted previously, around Jan-Feb. For
reference:

This example:
When compiling with -mbackchain -fstack-clash-protection currently no
probes are emitted. This patch adjusts the "allocate_stack" expander

The first tweak is to remove the TREE_OVERFLOW flag on INTEGER_CSTs because it
prevents them from being uniquized in LTO mode. The second, unrelated tweak
is to canonicalize the packable types made by gigi, so that at most one per
type is present in the GENERIC IL.
Tested on x86-64/Linux,
Two aliased objects must have distinct addresses, even if they have size zero,
so we make sure to allocate at least one byte for them.
Tested on x86-64/Linux, applied on the mainline.

We mark the type of In parameters in Ada with the const qualifier, but it is
stripped by free_lang_data_in_type so do not do it in LTO mode.
