GCN: Enable effective-target 'vect_hw_misalign'
... as made apparent by commit 4e1fcf44bdc582e71408175d75e025f5be8b0e55
"testsuite: vect: Require vect_hw_misalign in
gcc.dg/vect/vect-cost-model-1.c etc. [PR98238]"
causing:
PASS: gcc.dg/vect/vect-cost-model-1.c (test for excess errors)
-PASS: gcc.dg/vect/vect-cost-model-1.c scan-tree-dump vect "LOOP
VECTORIZED"
PASS: gcc.dg/vect/vect-cost-model-3.c (test for excess errors)
-PASS: gcc.dg/vect/vect-cost-model-3.c scan-tree-dump vect "LOOP
VECTORIZED"
PASS: gcc.dg/vect/vect-cost-model-5.c (test for excess errors)
-PASS: gcc.dg/vect/vect-cost-model-5.c scan-tree-dump vect "LOOP
VECTORIZED"
..., and similarly commit ffd47fb63ddc024db847daa07f8ae27fffdfcb28
"testsuite: Fix pr113431.c FAIL on sparc* [PR113431]" causing:
PASS: gcc.dg/vect/pr113431.c (test for excess errors)
PASS: gcc.dg/vect/pr113431.c execution test
-PASS: gcc.dg/vect/pr113431.c scan-tree-dump-times slp1 "optimized:
basic block part vectorized" 2
..., which this commit all restores, and also enables a good number of
further
FAIL -> PASS, UNSUPPORTED -> PASS, etc. progressions. There are also a
small
number of regressions, mostly in the SLP area apparently:
PASS: gcc.dg/vect/bb-slp-layout-12.c (test for excess errors)
+XPASS: gcc.dg/vect/bb-slp-layout-12.c scan-tree-dump-not slp1
"duplicating permutation node"
+XFAIL: gcc.dg/vect/bb-slp-layout-12.c scan-tree-dump-times slp1 "add
new stmt: [^\\n\\r]* = VEC_PERM_EXPR" 3
PASS: gcc.dg/vect/bb-slp-layout-6.c (test for excess errors)
+FAIL: gcc.dg/vect/bb-slp-layout-6.c scan-tree-dump slp2 "absorbing
input layouts"
PASS: gcc.dg/vect/pr97428.c (test for excess errors)
PASS: gcc.dg/vect/pr97428.c scan-tree-dump vect "Detected interleaving
load of size 8"
PASS: gcc.dg/vect/pr97428.c scan-tree-dump vect "Detected interleaving
store of size 16"
PASS: gcc.dg/vect/pr97428.c scan-tree-dump-not vect "gap of 6 elements"
-XFAIL: gcc.dg/vect/pr97428.c scan-tree-dump-times vect "vectorizing
stmts using SLP" 2
+FAIL: gcc.dg/vect/pr97428.c scan-tree-dump-times vect "vectorizing
stmts using SLP" 2
PASS: gcc.dg/vect/vect-33.c (test for excess errors)
+FAIL: gcc.dg/vect/vect-33.c scan-tree-dump vect "Vectorizing an
unaligned access"
PASS: gcc.dg/vect/vect-33.c scan-tree-dump-not optimized "Invalid sum"
PASS: gcc.dg/vect/vect-33.c scan-tree-dump-times vect "vectorized 1
loops" 1
..., so some further conditionalizing etc. seems necessary. These seem to
mostly appear next to pre-existing similar FAILs in related test cases.
(Overall, way more PASS than FAIL.)
