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/gfortran.dg/graphite/pr14741.f90 | 29 ++++++++++++++++++++++++++ 1 file changed, 29 insertions(+) create mode 100644 gcc/testsuite/gfortran.dg/graphite/pr14741.f90 (limited to 'gcc/testsuite/gfortran.dg/graphite/pr14741.f90') diff --git a/gcc/testsuite/gfortran.dg/graphite/pr14741.f90 b/gcc/testsuite/gfortran.dg/graphite/pr14741.f90 new file mode 100644 index 000000000..3fe1d690c --- /dev/null +++ b/gcc/testsuite/gfortran.dg/graphite/pr14741.f90 @@ -0,0 +1,29 @@ +! { dg-options "-O3 -ffast-math -floop-interchange -floop-block -fdump-tree-graphite-all" } + + INTEGER, PARAMETER :: N=1024 + REAL*8 :: A(N,N), B(N,N), C(N,N) + REAL*8 :: t1,t2 + A=0.1D0 + B=0.1D0 + C=0.0D0 + CALL cpu_time(t1) + CALL mult(A,B,C,N) + CALL cpu_time(t2) + write(6,*) t2-t1,C(1,1) +END program + +SUBROUTINE mult(A,B,C,N) + REAL*8 :: A(N,N), B(N,N), C(N,N) + INTEGER :: I,J,K,N + DO J=1,N + DO I=1,N + DO K=1,N + C(I,J)=C(I,J)+A(I,K)*B(K,J) + ENDDO + ENDDO + ENDDO +END SUBROUTINE mult + +! { dg-final { scan-tree-dump-times "number of SCoPs: 1" 1 "graphite" { xfail *-*-* } } } +! { dg-final { scan-tree-dump-times "will be loop blocked" 1 "graphite" { xfail *-*-* } } } +! { dg-final { cleanup-tree-dump "graphite" } } -- cgit v1.2.3
