+FAIL: gcc.dg/ipa/pr119530.c execution test
on i686-linux. The problem is that when long is just 32-bit and
so is unsigned, the testcase then behaves differently and should abort.
Fixed by making the argument long long instead.
While at it, just in case I've changed type of d variable to signed char
as well just in case there is -funsigned-char 8-bit int target or something
similar.

(e): Change argument type from long to long long.
This is a regression on some targets introduced I believe by r6-2055
which added mode argument to set_src_cost.
The problem here is that in the first iteration, mode is always QImode
and we get as -Os zero cost set_src_cost (const0_rtx, QImode, false).
But then we use the mode variable for iterating over int, partial int
and vector int modes, so for the second iteration we call set_src_cost
with mode which is at that time (machine_mode) (MAX_MODE_VECTOR_INT + 1).
In the x86 case that happens to be V2HFmode and we don't crash (and
compute the same 0 cost as we would for QImode).
But e.g. in the SPARC case (machine_mode) (MAX_MODE_VECTOR_INT + 1) is
MAX_MACHINE_MODE and that does all kinds of weird things especially
when doing ubsan bootstrap.
Fixed by always using QImode.

There seems to be inconsistency in the -fmax-errors option
naming. It is a generic option in common.opt (so applies
to all languages) but with the = character in it.
The gcobol.1 man page in one spot documents the generic
option (in the syntax, -fmax-errors=nerror) but in another
spot without the = character.
In common.opt it is
fmax-errors=
Common Joined RejectNegative UInteger Var(flag_max_errors)
-fmax-errors=<number> Maximum number of errors to report.
I hope the cobol addition is just a mistake, having -fmax-errors variant
without = character when Joined Separate would allow to specify
-fmax-errors 10 with the same meaning as -fmax-errors=10
but also -fmax-errors10 with the same meaning which is just weird.
Also, there is no UInteger and RejectNegative on it, so one can
also specific -fno-max-errors42 or -fmax-errors blah.
So, unless the spelling without = is intentional, here is a patch
to just remove it, the common option already should have arranged
for flag_max_errors to be set to the right number.
Or if it is intentional, I guess we'd need to at least add
RejectNegative UInteger (plus using atoi is generally undesirable
anywhere in the compiler because it does no error checking).
And the man page would need to be updated to specify both forms.

I was looking through options.cc diff between GCC 14 and 15, looking for
entries with added CL_Cobol where at least one other language is present
and was present before too. Besides the -fsyntax-only changes this is
the only other one I found, COBOL adds Var(cobol_include) to something
which didn't have a Var at all before and IMHO it is actively harmful.
Because one can specify multiple -include file1 -include file2 options,
both in C/C++ etc. and in COBOL as well (as documented in the man
page). A Var can track just one entry. cobol_langhook_handle_option
should use arg instead.

The comment is incorrect, fsyntax-only is not documented in c.opt,

and as such it applies to all languages, so adding CL_Cobol to
the CL_COMMON is both unnecessary and because of RejectNegative which
contradicts the generic option very harmful, because it makes
-fno-syntax-only invalid for all languages.

Andrew P. mentioned earlier he'd like to see in the dump files a note
whether it was a failed must tail call or not.
We already print that on the tailc/musttail pass side, because
print_gimple_stmt prints [must tail call] after the musttail calls.
The first hunk below does it for GENERIC CALL_EXPRs too (which is needed
for the expand diagnostics). That isn't enough though, because the
error on it was done first and then CALL_EXPR_MUST_TAIL_CALL flag was
cleared, so the dump didn't have it anymore. I've reordered the

In the three-parameter version of satisfy_declaration_constraints, when
't' isn't the most general template, then 't' won't correspond with
'args' after we augment the latter via add_outermost_template_args, and
so the instantiation context that we push via push_tinst_level isn't
quite correct: 'args' is a complete set of template arguments, but 't'
is not necessarily the most general template. This manifests as
misleading diagnostic context lines when issuing a satisfaction failure
error, e.g. the below testcase without this patch we emit:
In substitution of '... void A<int>::f<U>() ... [with U = int]'
and with this patch we emit:
In substitution of '... void A<int>::f<U>() ... [with U = char]'.
This patch fixes this by passing the original 'args' to push_tinst_level,
which ought to properly correspond to 't'.

This patch revisits the fix for PR 118097 and instead of deducing the
necessary operation type it just uses the value collected and streamed
by an earlier patch.
It is bigger than the ones for propagating value ranges and known bits
because we track constants both in parameters themselves and also in
memory they point to or within aggregates, we clone functions for them
and we do fancy things for some types of recursive calls.
In the case of constants in aggregates or passed by reference, the
situation should not change because the code creating jump functions
for them does not allow type-casts, unlike for the plain ones.
However, this patch changes how we handle them for the sake of
consistency and also so that we can try and eliminate this limitation
in the next stage 1.
