Ok for trunk and releases/gcc-15?
For releases/gcc-15, I would also want to cherry-pick r16-562-g20c25919132 that
converts
the test to use function body instead of three scan-assembler.
Changes since v1:
- Removed the acceptance of LDR as it's only generated without
r15-7373-g5163cf2ae14. Since
I'm currently looking into gcc-14 release, and made the patch in that scope,
I ran it on
trunk to ensure no new failures, but it's not actually needed.
Changes sice v2:
- Disabled sched1 and sched2 to limit the possible order of instructions.
--
Disable sched2 and sched3 to only have one order of instructions to
consider.
gcc/testsuite/ChangeLog:
* gcc.target/arm/unsigned-extend-2.c: Disable sched2 and sched3
and update function body to match.
