From e393f03b1a73d75901d1bc49c99123bdf534e120 Mon Sep 17 00:00:00 2001 From: Richard Biener Date: Mon, 18 Jan 2021 15:18:15 +0100 Subject: [PATCH] testsuite/97494 - adjust gcc.dg/vect/slp-11b.c Support for loop SLP splitting exposed that slp-11b.c has folding that breaks SLP discovery which isn't what was intended when the testcase was written. The following makes it SLP-able and "only" run into the issue that a load permutation is required. And tries to adjust the target selectors accordingly. 2021-01-18 Richard Biener PR testsuite/97494 * gcc.dg/vect/slp-11b.c: Adjust. --- gcc/testsuite/gcc.dg/vect/slp-11b.c | 12 +++++------- 1 file changed, 5 insertions(+), 7 deletions(-) diff --git a/gcc/testsuite/gcc.dg/vect/slp-11b.c b/gcc/testsuite/gcc.dg/vect/slp-11b.c index 0aece8092a8..c4d9ab0f36b 100644 --- a/gcc/testsuite/gcc.dg/vect/slp-11b.c +++ b/gcc/testsuite/gcc.dg/vect/slp-11b.c @@ -12,13 +12,13 @@ main1 () unsigned int out[N*8], a0, a1, a2, a3, a4, a5, a6, a7, b1, b0, b2, b3, b4, b5, b6, b7; unsigned int in[N*8] = {0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,50,51,52,53,54,55,56,57,58,59,60,61,62,63}; - /* Requires permutation - not SLPable. */ + /* Requires permutation for SLP. */ for (i = 0; i < N*2; i++) { out[i*4] = (in[i*4] + 2) * 3; out[i*4 + 1] = (in[i*4 + 2] + 2) * 7; out[i*4 + 2] = (in[i*4 + 1] + 7) * 3; - out[i*4 + 3] = (in[i*4 + 3] + 3) * 4; + out[i*4 + 3] = (in[i*4 + 3] + 3) * 7; } /* check results: */ @@ -27,7 +27,7 @@ main1 () if (out[i*4] != (in[i*4] + 2) * 3 || out[i*4 + 1] != (in[i*4 + 2] + 2) * 7 || out[i*4 + 2] != (in[i*4 + 1] + 7) * 3 - || out[i*4 + 3] != (in[i*4 + 3] + 3) * 4) + || out[i*4 + 3] != (in[i*4 + 3] + 3) * 7) abort (); } @@ -43,7 +43,5 @@ int main (void) return 0; } -/* { dg-final { scan-tree-dump-times "vectorized 1 loops" 1 "vect" { target { vect_strided4 && vect_int_mult } } } } */ -/* { dg-final { scan-tree-dump-times "vectorized 0 loops" 1 "vect" { target { ! { vect_strided4 && vect_int_mult } } } } } */ -/* { dg-final { scan-tree-dump-times "vectorizing stmts using SLP" 0 "vect" { target { ! vect_load_lanes } } } } */ -/* { dg-final { scan-tree-dump-times "vectorizing stmts using SLP" 1 "vect" { target { vect_load_lanes } } } } */ +/* { dg-final { scan-tree-dump-times "vectorized 1 loops" 1 "vect" { target { { vect_strided4 || vect_perm } && vect_int_mult } } } } */ +/* { dg-final { scan-tree-dump-times "vectorizing stmts using SLP" 1 "vect" { target { vect_perm && vect_int_mult } } } } */ -- 2.30.2
