I don't see how a bug reported in 2003 against 3.2 and marked as failing up to
4.0 could possibly be related in any way with VTA. Clearly that bug was fixed.
Sure, VTA does perform poorly with these testcases, but this is not the bug
that was reported, and we already have other bugs about VTA performance.

on the top of the 4.5 branch. Everything else looks good now, so we can
as well claim its one of the dups of the var-tracking-is-slow-and-memory-hungry
bugs.
90s var-tracking and then giving up is quite bad. Can't we estimate instead
of compute and give up?
4.4 needed 186s even without the var-tracking slowness, so at least we
have recovered for that elsewhere... (in operand-scan, aka alias-improvements)

The problem is that I call compute_inline_parameters() whenever I
change a single call site, even when the caller is the same. The
following patch (which I am about to bootstrap and test) should fix
that:

Today we regressed with the introduction of IPA-SRA at -O2 and -O3:
ipa SRA : 387.53 (78%) usr 0.08 ( 5%) sys 387.79 (77%) wall

my bet is at the alias-oracle walking (walk_aliased_vdefs), which is not
properly limited.

this is tree after ehcleanup merge. Perhaps memory problems was solved with
it, we still have compile time issues with PRE though.

With the mainline on ppc-darwin we have a huge problem in the scheduler:
scheduling : 131.99 (44%) usr 52.35 (75%) sys 231.63 (46%) wall
PRE (GCSE) is also a problem too:
PRE : 38.78 (13%) usr 1.82 ( 3%) sys 73.43 (15%) wall
For the scheduler at least we have linked lists which we allocate a lot of.

On the mainline (without checking disabled so we cannot compare it to 3.4.0 or another version and
maybe this is also not the right timings for this test without checking):
global alloc : 19.38 (37%) usr 0.29 (11%) sys 39.92 (36%) wall
expand : 6.90 (13%) usr 0.06 ( 2%) sys 14.47 (13%) wall
