Hi all,
Attached patch fixes both the simplification and translation for
intrinsic UBOUND/LBOUND to get correct results in all cases I could
imagine. This clears completely PR 29489 & 29712. The logic behind
both patches is straightforward, and the only thing noteworthy is
that {L,U}BOUND simplification provided by this patch is a bit
pessimistic: there are a few more cases that we should be able to
simplify here, but for thoses cases the folding of code emitted will
take sufficient to not need runtime evaluation.
I'm in no position to regtest this patch, being on the road with a
very slow laptop. I bootstrapped it, and regtested only {L,U}BOUND-
related testcases. Moreover, the patch is confined to two routines,
so I'm confident it doesn't break other things. Nonetheless, I'd
appreciate if a reviewer could give it a spin.
OK for mainline, 4.2 and 4.1?
FX
