I'd be really better if more people had access to a unified test setup and

I think it would make sense to test it using sh-sim on SH2 big-endian and
little endian at least, as that doesn't have an FPU and hence would run
tests utilizing soft-fp.
After building the toolchain for --target=sh-elf, you can use this to run
the testsuite in the simulator:
make -k check RUNTESTFLAGS="--target_board=sh-sim\{-m2/-ml,-m2/-mb}"
(add make -j parameter according to you needs -- it will be slow)
Let me know if you have any further questions.

The patterns were written and tested to the best of our knowledge at that
time many years ago. Nobody thought that we'll get a 2nd combine pass after
RA. Anyway, I'll have a look at the remaining patterns.
Sebastien, in the meantime you could also try out and test your changes on
the latest GCC 14 branch, which shouldn't have those issues.

originally contracted by Hitachi to complement their own in-house C compiler
and also to allow sh-linux to happen at some point. It was entertained by
Renesas for a while through further contracted support work but eventually
they have abandoned it. STmicro was also a licensee of the SH4 CPU for
their TV set top boxes and had a few guys submitting patches now and then
for a while. But the whole thing basically went on life support about 10
years ago.
Perhaps Jeff or others can give more insight on the historical parts.

basically to run an additional loop pass after combine and
split1. The main purpose is to hoist constant loads out of loops. Such
constant loads might be formed (in this particular case) during combine
transformations.
The patch adds a new file gcc/config/sh/sh_loop.cc, which has some boiler-
plate code copy pasted from other places to get the loop pass setup and
going.
Any thoughts on this way of doing it?

The attached patch improves comparisons such as
'unsigned int <= 0x7FFF' on SH.
As mentioned in the PR, for some reason, those comparisons do not go

I somehow initially forgot to implement DImode GBR based loads/stores.
Attached patch does that and also fixes a problem with the GBR address
mode optimization.

This one refactors some copy pasta that my previous patch regarding this

bit stores. It also fixes the bug reported in PR 54925 which popped up

Hello,
Some of the things I've done in 4.8 to improve SH T bit handling turned
out to produce wrong code. The attached patch fixes that by introducing
an SH specific RTL pass.

The test case pr54089-3.c started to fail a while ago, because of the
broken test for load of constant 31. Committed as obvious to trunk and

Hello,
The attached patch fixes volatile mem stores on SH so that they won't
result in redundant sign/zero extensions and will utilize available
addressing modes. This is similar to what has been done to fix memory
loads in http://gcc.gnu.org/ml/gcc-patches/2013-06/msg01315.html
