The following fixes that and also plugs the hole of trapping references not pruned in case they are not catched by the actuall call clobbering it. At -Os we hit the same issue in RTL PRE and postreload-gcse has even more incomplete checks so the patch adjusts both of those as well. 2021-07-08 Richard Biener PR tree-optimization/101373 * tree-ssa-pre.c (prune_clobbered_mems): Also prune trapping references when the BB may not return. (compute_avail): Pass in the function we're working on and replace cfun references with it. Externally throwing const calls also possibly terminate the function. (pass_pre::execute): Pass down the function we're working on. * gcse.c (compute_hash_table_work): Externally throwing const/pure calls also need record_last_mem_set_info. * postreload-gcse.c (record_opr_changes): Looping or externally throwing const/pure calls also need record_last_mem_set_info. * g++.dg/torture/pr101373.C: New testcase, XFAILed. * gnat.dg/opt95.adb: Likewise.

[InstCombine] fold icmp slt/sgt of offset value with constant
This follows up patches for the unsigned siblings:
0c400e895306
c7b658aeb526
We are translating an offset signed compare to its
unsigned equivalent when one end of the range is
at the limit (zero or unsigned max).
(X + C2) >s C --> X X >u (C ^ SMAX) (if C == C2)
This probably does not show up much in IR derived
from C/C++ source because that would likely have
'nsw', and we have folds for that already.
As with the previous unsigned transforms, the folds
could be generalized to handle non-constant patterns:
https://alive2.llvm.org/ce/z/Y8Xrrm
; sgt
define i1 @src(i8 %a, i8 %c) {
%c2 = add i8 %c, 1
%t = add i8 %a, %c2
%ov = icmp sgt i8 %t, %c
ret i1 %ov
}
define i1 @tgt(i8 %a, i8 %c) {
%c_off = sub i8 127, %c ; SMAX
%ov = icmp ult i8 %a, %c_off
ret i1 %ov
}
https://alive2.llvm.org/ce/z/c8uhnk
; slt
define i1 @src(i8 %a, i8 %c) {
%t = add i8 %a, %c
%ov = icmp slt i8 %t, %c
ret i1 %ov
}
define i1 @tgt(i8 %a, i8 %c) {
%c_offnot = xor i8 %c, 127 ; SMAX
%ov = icmp ugt i8 %a, %c_offnot
ret i1 %ov
}

Re: [CI-NOTIFY]: TCWG Bisect tcwg_bmk_tk1/llvm-master-arm-spec2k6-Os - Build # 9 - Successful!
Hi Sanjay,
On 32-bit ARM your patch appears to increase code size of BZ2_decompress from
SPEC2006’s 401.bzip2 by 50% — from 7.5K to 11K. This increases overall code
size of 401.bzip2 benchmark by 10%.
Would you please investigate?
Please let us know if you need help reproducing the problem.
Regards,

[CI-NOTIFY]: TCWG Bisect tcwg_bmk_tk1/gnu-release-arm-spec2k6-O3_LTO - Build # 28 - Successful!
Successfully identified regression in *gcc* in CI configuration tcwg_bmk_gnu_tk1/gnu-release-arm-spec2k6-O3_LTO. So far, this commit has regressed CI configurations: - tcwg_bmk_gnu_tk1/gnu-release-arm-spec2k6-O3_LTO Culprit: commit c7207339a7dbce5b68f872064e624dcf1639ba46 Author: Wilco Dijkstra Date: Mon Oct 14 12:21:14 2019 + [ARM] Switch to default sched pressure algorithm Currently the Arm backend selects the alternative sched pressure algorithm. The issue is that this doesn't take register pressure into account, and so it causes significant additional spilling on Arm where there are only 14 allocatable registers. Building SPEC2006 showed significant codesize gains with the default pressure algorithm, so switch back to that. PR77308 shows ~800 fewer instructions. SPECINT2006 is ~0.6% faster on Cortex-A57 together with the other DImode patches. Overall SPEC codesize is 1.1% smaller. gcc/ * config/arm/arm.c (arm_option_override): Don't override sched pressure algorithm.
