Make tree_expr_nonnegative_warnv_p recurse into SSA names
The upcoming patch to move sqrt and cbrt simplifications to match.pd
caused a regression because the (abs @0)->@0 simplification didn't
trigger for:
(abs (convert (abs X)))
The simplification is based on tree_expr_nonnegative_p, which at
the moment just gives up if it sees an SSA_NAME.
This patch makes tree_expr_nonnegative_p recurse into SSA name
definitions, but limits the depth of recursion to a small number
for the reason mentioned in the comment (adapted from an existing
comment in gimple_val_nonnegative_real_p). The patch reuses code
in tree-vrp.c, moving it to gimple-fold.c. It also replaces calls
to gimple_val_nonnegative_real_p with calls to tree_expr_nonnegative_p.
A knock-on effect is that we can now prove _i_589 < 0 is false in
sequences like:
i_1917 = ASSERT_EXPR <i_1075, i_1075 == 0>;
_i_589 = (const int) i_1917;
_i_1507 = ASSERT_EXPR <_i_589, _i_589 < 0>;
This defeats an assert in tree-vrp.c that ASSERT_EXPR conditions
are never known to be false. Previously the assert only ever used
local knowledge and so would be limited to cases like x != x for
integer x. Now that we use global knowledge it's possible to prove
the assertion condition is false in blocks that are in practice
unreachable. The patch therefore removes the assert.
Bootstrapped & regression-tested on x86_64-linux-gnu. I didn't write
a specific test because this is already covered by the testsuite if
the follow-on patch is also applied.

Move fold_trunc_transparent_mathfn to match.pd
This moves the fold rules for trunc, floor, ceil, round, nearbyint and
rint in one go, since they're tested as a group. Most of the code is
supporting the f(x)->x fold when x is known to be integer-valued.
Like with the non-negative test, this is probably more elegantly handled
by tracking range information for reals, but until that happens, I think
we should handle it analogously to tree_expr_nonnegative_p.
I've incorporated the fix for PR68031 in the new version of
integer_valued_real_p. However, it seemed confusing to test for an
SSA name at the head of the function rather than the case statement,
and not fall through to tree_simple_nonnegative_warnv_p (which
conceptually shouldn't care whether an update is in progress).
But tree_simple_nonnegative_warnv_p is a no-op for SSA names,
so I simply changed it to:
return (!name_registered_for_update_p (t)
&& depth < PARAM_VALUE (PARAM_MAX_SSA_NAME_QUERY_DEPTH)
&& gimple_stmt_nonnegative_warnv_p (SSA_NAME_DEF_STMT (t),
strict_overflow_p, depth));
and used that in the new code too.
Doing these folds later meant that IPA would start to use information
about the aborting sinf and floor in 20030125-1.c before the folds
kicked in. I changed them from noinline to weak to stop that.
Tested on x86_64-linux-gnu, aarch64-linux-gnu and arm-linux-gnueabi.

Move fold_trunc_transparent_mathfn to match.pd
This moves the fold rules for trunc, floor, ceil, round, nearbyint and
rint in one go, since they're tested as a group. Most of the code is
supporting the f(x)->x fold when x is known to be integer-valued.
Like with the non-negative test, this is probably more elegantly handled
by tracking range information for reals, but until that happens, I think
we should handle it analogously to tree_expr_nonnegative_p.
I've incorporated the fix for PR68031 in the new version of
integer_valued_real_p. However, it seemed confusing to test for an
SSA name at the head of the function rather than the case statement,
and not fall through to tree_simple_nonnegative_warnv_p (which
conceptually shouldn't care whether an update is in progress).
But tree_simple_nonnegative_warnv_p is a no-op for SSA names,
so I simply changed it to:
return (!name_registered_for_update_p (t)
&& depth < PARAM_VALUE (PARAM_MAX_SSA_NAME_QUERY_DEPTH)
&& gimple_stmt_nonnegative_warnv_p (SSA_NAME_DEF_STMT (t),
strict_overflow_p, depth));
and used that in the new code too.
Doing these folds later meant that IPA would start to use information
about the aborting sinf and floor in 20030125-1.c before the folds
kicked in. I changed them from noinline to weak to stop that.
Tested on x86_64-linux-gnu, aarch64-linux-gnu and arm-linux-gnueabi.

Make tree_expr_nonnegative_warnv_p recurse into SSA names
The upcoming patch to move sqrt and cbrt simplifications to match.pd
caused a regression because the (abs @0)->@0 simplification didn't
trigger for:
(abs (convert (abs X)))
The simplification is based on tree_expr_nonnegative_p, which at
the moment just gives up if it sees an SSA_NAME.
This patch makes tree_expr_nonnegative_p recurse into SSA name
definitions, but limits the depth of recursion to a small number
for the reason mentioned in the comment (adapted from an existing
comment in gimple_val_nonnegative_real_p). The patch reuses code
in tree-vrp.c, moving it to gimple-fold.c. It also replaces calls
to gimple_val_nonnegative_real_p with calls to tree_expr_nonnegative_p.
A knock-on effect is that we can now prove _i_589 < 0 is false in
sequences like:
i_1917 = ASSERT_EXPR <i_1075, i_1075 == 0>;
_i_589 = (const int) i_1917;
_i_1507 = ASSERT_EXPR <_i_589, _i_589 < 0>;
This defeats an assert in tree-vrp.c that ASSERT_EXPR conditions
are never known to be false. Previously the assert only ever used
local knowledge and so would be limited to cases like x != x for
integer x. Now that we use global knowledge it's possible to prove
the assertion condition is false in blocks that are in practice
unreachable. The patch therefore removes the assert.
Bootstrapped & regression-tested on x86_64-linux-gnu. I didn't write
a specific test because this is already covered by the testsuite if
the follow-on patch is also applied.
