Hi Jeff,
Indeed, that sounds like a good idea. I will make this separate and
send it after the required testing.
I'll see what can be done about a testcase.

Hi Roger,
I've (accidentally) found a codegen regression that I bisected down to
this patch.
For these two functions:
typedef struct {
float minx, miny;
float maxx, maxy;
} AABB;
int TestOverlap(AABB a, AABB b) {
return a.minx <= b.maxx
&& a.miny <= b.maxy
&& a.maxx >= b.minx

In the new version I both restore the INSN_CODE as mentioned here and
I also call recog when I commit the offset change (because there may
be a change from no offset to some offsets).
I have also

Hi all,
I'm pinging to discuss again if we want to move this forward for GCC14.
I did some testing again and I haven't been able to find obvious

instruction is valid.
Any ideas on how to solve this issue is appreciated.

failing with an ICE but I believe that it's not an issue of this change.
