Hi,
I would like to ping this for comments.

In this patch, "subreg:DI (x:SI)" is used. I' thinking that this
may be a concern, while it maybe acceptable for current code.

arg_max_access_size_given_by_arg_p this interprets a memory access

Second thought on this, we should just add define_split rather than
define_insn_and_split, otherwise we might hit the same issue again,
and I expect the split pattern will only used in combine pass.

My recent tweak to the zeroextendqihi2 pattern on xstormy16 incorrectly
handled the case where the operand was a MEM. MEM operands use a longer
encoding than REG operands, and the incorrect instruction length resulted
in assembler errors (as reported by Jeff Law). This patch restores the

The binutils support is lingering on-list since Jan 2022:
https://sourceware.org/pipermail/binutils/2022-January/119388.html
If we get an OK on that one, we will rebase, retest, and merge it.
Thanks,

hi Jiawei
Please ignore my previous reply. I accidently sent the email before I finished
it.
Sorry for that!
I downloaded the series of patches from you and found in some cases
it fails to generate zcmp push and pop insns.

char my_getchar();
int test_s0()

int a = my_getchar();
Thanks Evandro,
That one works. I’ll run the new cost model and sched modules through a number
of workloads and come back with the results.
Cheers,

Hi,
insert_debug_temp_for_var_def has some strange code whereby it creates debug
temporaries for SINGLE_RHS (RHS for gimple_assign_single_p) but not for other
RHS in the same situation. Removing it saves 25% of compilation time at -g -O
for a pathological testcase I have.

I think it's best to specify the default behavior of nan_state, since
it's not obvious that nan_state() defaults to TRUE. Also, this avoids
the ugly nan_state(false, false) idiom.
Will commit pending tests.

It was recently pointed out that we generate symbolic links to ghost files
when building the GNAT tools, as the mlib-tgt-specific-*.adb files are gone.
Tested on x86-64/Linux, applied on the mainline. I'll backport this onto
branches after the GCC 13.1 release is out.
