we can't do VCONDEQ, we _can_ compute op0 but do not have vcond_mask which
we assume here. So this is a mismatch between ISEL and vector lowering
or alternatively a failure to - for non-mask vectors - provide a fallback
via masking.
For vcond_mask I see there is v2sfv2si but no v4sfv4si, so not sure whether
this can be tackled on the backend side.
Note for a masking fallback we'd have to ensure support for integer mode
bitwise ops as well as view-converting V4SF to and from V4SI. There is
/* Lower mask typed, non-vector mode VEC_COND_EXPRs to bitwise operations.
Those can end up generated by folding and at least for integer mode masks
we cannot expect vcond expanders to exist. We lower a ? b : c
to (b & a) | (c & ~a). */
if (VECTOR_BOOLEAN_TYPE_P (TREE_TYPE (lhs))
&& !VECTOR_MODE_P (mode))
{
gcc_assert (types_compatible_p (TREE_TYPE (op0), TREE_TYPE (op1)));
gimple_seq stmts = NULL;
tree type = TREE_TYPE (lhs);
location_t loc = gimple_location (stmt);
tree tem0 = gimple_build (&stmts, loc, BIT_AND_EXPR, type, op1, op0);
tree tem1 = gimple_build (&stmts, loc, BIT_NOT_EXPR, type, op0);
tree tem2 = gimple_build (&stmts, loc, BIT_AND_EXPR, type, op2, tem1);
tree tem3 = gimple_build (&stmts, loc, BIT_IOR_EXPR, type, tem0, tem2);
gsi_insert_seq_before (gsi, stmts, GSI_SAME_STMT);
return gimple_build_assign (lhs, tem3);
}
but as said the immediate failure is that veclower thinks we can handle
_37 = vect_vec_iv_.13_32 == { 0, 0, 0, 0 };
vect_iftmp.14_38 = VEC_COND_EXPR <_37, { 1.0e+0, 1.0e+0, 1.0e+0, 1.0e+0 }, {
0.0, 0.0, 0.0, 0.0 }>;
but ISEL thinks we cannot. I will look into that.

--- Comment #3 from Richard Biener <rguenth at gcc dot gnu.org> ---
Interestingly vector lowering ends up in
can_vcond_compare_p (code=EQ, value_mode=E_V4SFmode, cmp_op_mode=E_V4SImode)
via expand_vec_cond_expr_p calling vcond_icode_p where get_vcond_icode
gets us CODE_FOR_vcondv4sfv4si. And the key difference is that
can_vcond_compare_p uses unsigned_optab_p (code) (false for EQ) but
ISEL passes down true (the type is unsigned). For EQ/NE whether we use
the signed or unsigned optab shouldn't matter but the query function
canonicalizes via
/* Return whether RTL code CODE corresponds to an unsigned optab. */
static bool
unsigned_optab_p (enum rtx_code code)
{
return code == LTU || code == LEU || code == GTU || code == GEU;
}
it's not documented that one or the other form is canonical though.
The easiest is to try both in ISEL.

Sorry for the breakage, my patch shouldn't have modified the behavior for Neon.
I just moved the vcond_mask expander from neon.md to vec-common.md.
With Neon, I think we should have both v4sfv4si and v2sfv2si, unlike MVE where
the v2 variant does not exist.

tree-optimization/105312 - fix ISEL VCOND expansion
The following aligns ISEL VEC_COND_EXPR expansion using VCOND
with the optab query done by vector lowering. Instead of only
allowing the signed optab to provide EQ/NE compares we allow both
here though since there seems to be no documented canonicalization.

tree-optimization/105312 - fix ISEL VCOND expansion
The following aligns ISEL VEC_COND_EXPR expansion using VCOND
with the optab query done by vector lowering. Instead of only
allowing the signed optab to provide EQ/NE compares we allow both
here though since there seems to be no documented canonicalization.

* gimple-isel.cc (gimple_expand_vec_cond_expr): Query both

I'm guessing not but is it worth adding the SPARC testcase from the dupe, given
this one is only run for arm?

r11-10018-g33914983cf3734c2f8079963ba49fcc117499ef3 fixed PR105312 and

a test case for target/arm but the duplicate PR105573 has a test case for
target/sparc that was uncommitted until now.
