The failure happens in store_motion in gcse.c.
We have two objects on the stack with disjoint lifetimes that overlap. They
have different MEM_EXPRS, and some of the mems also have different alias sets.
They have

PR 25130 is a gcse problem, and there are some curious similarities. We have
two objects on the stack with the same address, and gcse is emitting new RTL
referring to the wrong one, which means we have mems with bad

This is indeed a gcse problem. It is a problem with the load motion support.
There are some similarities to PR 24804 here. We have multiple overlapping
objects on the stack, that have mems with different MEM_EXPR

The spurious warning is a problem because binutils is compiled by -Werror by
default now, when compiled by gcc. This spurious warning thus causes a build
failure for binutils. This build failure does not show up

Delay auto-inc generation until after determining which regs live across
setjmp.
This is my proposed untested

Oops. That patch should have a | PROP_AUTOINC in the new update_life_info
call. That would explain why I was seeing some unexpected de-optimizations
with the patch.
