I can't reproduce that, but I fail to see why we need two separate
variables, one with actual value and one tracking if the value is valid.
So, I'm going with:
2020-10-21 Jakub Jelinek <jakub@redhat.com>
* env.c (parse_target_offload): Change new_offload var type to int,
preinitialize to -1, remove found var and test new_offload != -1
instead of found.
This was slated to be moved last year, as its only use is in tree-vrp.c
There are no functional changes. It's just a move and a rename.
gcc/ChangeLog:
* vr-values.h: Remove simplify_cond_using_ranges_2.
(range_fits_type_p): New.
* vr-values.c (range_fits_type_p): Remove static qualifier.
(vrp_simplify_cond_using_ranges): Move...

Do not crash when AsanThread::GetStackVariableShadowStart does not find
a variable for a pointer on a shadow stack.

* gcc.target/aarch64/advsimd-intrinsics/vstX_lane.c (CMT):
Adopt the same style used in the rest of the file.
There is a discrepancy in the way we report -Walloca-larger-than=
errors on 32-bit versus 64-bit architectures, due to the nature of
ranges derived from a cast operation.
For the Walloca-1 tests on 64-bits we get:
int num.0_1;
long unsigned int _2;
<bb 2> [local count: 1073741824]:
num.0_1 = num;
_2 = (long unsigned int) num.0_1;
s_8 = __builtin_alloca (_2);
Because of the cast of a 32-bit quantity into a 64-bit quantity in _2,
ranger calculates its range as:
long unsigned int [0, 2147483647][18446744071562067968, +INF]
Thus excluding the numbers that can't exist in _2.
This causes the Walloca pass to report that the argument to alloca may be
too large.
However, for -m32 on x86, the gimple is:
int num.0_1;
unsigned int num.1_2;
<bb 2> [local count: 1073741824]:
num.0_1 = num;
num.1_2 = (unsigned int) num.0_1;
s_8 = __builtin_alloca (num.1_2);
Since num.0_1 and num.1_2 are of the same size, we cannot determine
any useful range, so we return VARYING. In the Walloca pass, VARYING
basically means "unbounded" (no known bounds for the alloca call argument).
So on 32-bits, the error message issued is slightly different:
warning: unbounded use of ‘alloca’
versus on 64-bits, where due to the cast, it is:
warning: argument to ‘alloca’ may be too large
In reality both versions of the IL show an unbounded call, but in one
version (64-bits) we can exclude some values so we assume the range
was provided, but it was out of bounds.
I've mentioned various times that all these diagnostics passes
(alloca, restrict, printf, etc), could benefit from less specific error
messages since what we have can potentially confuse the user. However,
no consensus has been reached on how to report these things.
In the meantime, this patch adjusts the testcase to accept both variants.

rather than "tim" for its time-related fields.

In adding the DECL_LOCAL_DECL handling, I'd forgotten that the
parm-decls also need cloning -- and resetting of their DECL_CONTEXT.
Also, any default args need droping when adding an alias, as those are

there's no exising namespace decl, but that seems like the right thing

This sets things up so we can share range handling of builtins between
vr_values and ranger. It is meant to refactor the code so that we can
verify that both implementations yield the same results.
First, we abstract out gimple_ranger::range_of_builtin_call into an externally
visible counterpart that can be called from vr_values. It will take a
range_query since both ranger and vr_values inherit from this base class.
Then we abstract out all the builtin handling in vr_values into a separate
method that is easier to compare against.
Finally, we call the ranger version from vr_values and compare it with the
vr_values version. Since this proves both versions return the same,
we can remove vr_values::extract_range_builtin in a follow-up patch.
The vr_values::range_of_expr change brings the vr_values version up to par
with the ranger version. It should've handled non-SSA's. This was
a small oversight that went unnoticed because the vr_value version isn't
stressed nearly as much as the ranger version. The change is needed because
the ranger code handling builtins calls, may call it for integer arguments
in range_of_builtin_ubsan_call.
There should be no change in functionality.
