From 554fd8c5195424bdbcabf5de30fdc183aba391bd Mon Sep 17 00:00:00 2001 From: upstream source tree Date: Sun, 15 Mar 2015 20:14:05 -0400 Subject: obtained gcc-4.6.4.tar.bz2 from upstream website; verified gcc-4.6.4.tar.bz2.sig; imported gcc-4.6.4 source tree from verified upstream tarball. downloading a git-generated archive based on the 'upstream' tag should provide you with a source tree that is binary identical to the one extracted from the above tarball. if you have obtained the source via the command 'git clone', however, do note that line-endings of files in your working directory might differ from line-endings of the respective files in the upstream repository. --- gcc/testsuite/gcc.dg/vect/slp-33.c | 111 +++++++++++++++++++++++++++++++++++++ 1 file changed, 111 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/vect/slp-33.c (limited to 'gcc/testsuite/gcc.dg/vect/slp-33.c') diff --git a/gcc/testsuite/gcc.dg/vect/slp-33.c b/gcc/testsuite/gcc.dg/vect/slp-33.c new file mode 100644 index 000000000..4b67d894e --- /dev/null +++ b/gcc/testsuite/gcc.dg/vect/slp-33.c @@ -0,0 +1,111 @@ +/* { dg-require-effective-target vect_int } */ + +#include +#include "tree-vect.h" + +#define N 8 + +int +main1 () +{ + int i; + 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}; + float out2[N*8]; + + /* SLP with unrolling by 4. */ + for (i = 0; i < N; i++) + { + a0 = in[i*7] + 5; + a1 = in[i*7 + 1] + 6; + a2 = in[i*7 + 2] + 7; + a3 = in[i*7 + 3] + 8; + a4 = in[i*7 + 4] + 9; + a5 = in[i*7 + 5] + 10; + a6 = in[i*7 + 6] + 11; + + b0 = a0 * 3; + b1 = a1 * 2; + b2 = a2 * 12; + b3 = a3 * 5; + b4 = a4 * 8; + b5 = a5 * 4; + b6 = a6 * 3; + + out[i*7] = b0 - 2; + out[i*7 + 1] = b1 - 3; + out[i*7 + 2] = b2 - 2; + out[i*7 + 3] = b3 - 1; + out[i*7 + 4] = b4 - 8; + out[i*7 + 5] = b5 - 7; + out[i*7 + 6] = b6 - 3; + } + + /* check results: */ + for (i = 0; i < N; i++) + { + if (out[i*7] != (in[i*7] + 5) * 3 - 2 + || out[i*7 + 1] != (in[i*7 + 1] + 6) * 2 - 3 + || out[i*7 + 2] != (in[i*7 + 2] + 7) * 12 - 2 + || out[i*7 + 3] != (in[i*7 + 3] + 8) * 5 - 1 + || out[i*7 + 4] != (in[i*7 + 4] + 9) * 8 - 8 + || out[i*7 + 5] != (in[i*7 + 5] + 10) * 4 - 7 + || out[i*7 + 6] != (in[i*7 + 6] + 11) * 3 - 3) + abort (); + } + + /* SLP with unrolling by 4. */ + for (i = 0; i < N*2; i++) + { + out[i*3] = (in[i*3] + 2) * 3; + out[i*3 + 1] = (in[i*3 + 1] + 2) * 7; + out[i*3 + 2] = (in[i*3 + 2] + 7) * 3; + } + + /* check results: */ + for (i = 0; i < N*2; i++) + { + if (out[i*3] != (in[i*3] + 2) * 3 + || out[i*3 + 1] != (in[i*3 + 1] + 2) * 7 + || out[i*3 + 2] != (in[i*3 + 2] + 7) * 3) + abort (); + } + + /* SLP with unrolling by 4. */ + for (i = 0; i < N*2; i++) + { + out2[i*3] = (float) (in[i*3] * 2 + 5) ; + out2[i*3 + 1] = (float) (in[i*3 + 1] * 3 + 7); + out2[i*3 + 2] = (float) (in[i*3 + 2] * 5 + 4); + } + + /* check results: */ + for (i = 0; i < N*2; i++) + { + if (out2[i*3] != (float) (in[i*3] * 2 + 5) + || out2[i*3 + 1] != (float) (in[i*3 + 1] * 3 + 7) + || out2[i*3 + 2] != (float) (in[i*3 + 2] * 5 + 4)) + abort (); + } + + + return 0; +} + +int main (void) +{ + check_vect (); + + main1 (); + + return 0; +} + +/* { dg-final { scan-tree-dump-times "vectorized 3 loops" 1 "vect" {target {vect_uintfloat_cvt && vect_int_mult} } } } */ +/* { dg-final { scan-tree-dump-times "vectorized 2 loops" 1 "vect" {target {{! { vect_uintfloat_cvt}} && vect_int_mult} } } } */ +/* { dg-final { scan-tree-dump-times "vectorized 0 loops" 1 "vect" {target {{! { vect_uintfloat_cvt}} && {! {vect_int_mult}}} } } } */ +/* { dg-final { scan-tree-dump-times "vectorizing stmts using SLP" 3 "vect" {target {vect_uintfloat_cvt && vect_int_mult} } } } */ +/* { dg-final { scan-tree-dump-times "vectorizing stmts using SLP" 2 "vect" {target {{! { vect_uintfloat_cvt}} && vect_int_mult} } } } */ +/* { dg-final { scan-tree-dump-times "vectorizing stmts using SLP" 0 "vect" {target {{! { vect_uintfloat_cvt}} && {! {vect_int_mult}}} } } } */ +/* { dg-final { cleanup-tree-dump "vect" } } */ + -- cgit v1.2.3
