The isolate-paths pass is activated by various -f flags, but also by

least one of the -f flags, but those that detect, warn about and

As auto_inc_dec pass combines incs and mems from different insns, it
often causes regs to temporarily hold a value different from the one
it would before the transformation. Debug insns within that range
would therefore end up binding to the wrong expression after the
transformation.

Hi all,
My recent patch which replaced
(float_type)int_var1 CMP (float_type)int_var2
with
int_var1 CMP int_var2
may generate unordered comparisons of integer values which are both
unnecessary and may also upset later passes.
This patch fixes the problem and bootstraps without regressions on

Hi!
Regtested on x86_64-unknown-linux, installing on
aldot/fortran-fe-stringpool.
We did not free global symbols. For a simplified abstract_type_3.f03
valgrind reports:
96 bytes in 1 blocks are still reachable in loss record 461 of 602
at 0x48377D5: calloc (vg_replace_malloc.c:711)
by 0x21
Is this fixed by Richard's patch to 87640? if so, perhaps this is a
duplicate of said PR.

All,
This patch implements C++2a proposal P0330R2 Literal Suffixes for
ptrdiff_t and size_t*. It's not official yet but looks very likely to
pass. It is incomplete because I'm looking for some opinions. 9We also
might wait 'till it actually passes).

Richard requested that all tests use issue links rather than numbers
so as not to confuse with gcc's bugzilla tracker.
Posting just the patch overlay to original that applies just that.
