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/g77/intrinsic-unix-erf.f | 61 ++++++++++++++++++++++ 1 file changed, 61 insertions(+) create mode 100644 gcc/testsuite/gfortran.dg/g77/intrinsic-unix-erf.f (limited to 'gcc/testsuite/gfortran.dg/g77/intrinsic-unix-erf.f') diff --git a/gcc/testsuite/gfortran.dg/g77/intrinsic-unix-erf.f b/gcc/testsuite/gfortran.dg/g77/intrinsic-unix-erf.f new file mode 100644 index 000000000..460ddeea4 --- /dev/null +++ b/gcc/testsuite/gfortran.dg/g77/intrinsic-unix-erf.f @@ -0,0 +1,61 @@ +c { dg-do run } +c intrinsic-unix-erf.f +c +c Test Bessel function intrinsics. +c These functions are only available if provided by system +c +c David Billinghurst +c + real x, a + double precision dx, da + logical fail + common /flags/ fail + fail = .false. + + x = 0.6 + dx = x +c ERF - error function + a = 0.6038561 + da = a + call c_r(ERF(x),a,'ERF(real)') + call c_d(ERF(dx),da,'ERF(double)') + call c_d(DERF(dx),da,'DERF(double)') + +c ERFC - complementary error function + a = 1.0 - a + da = a + call c_r(ERFC(x),a,'ERFC(real)') + call c_d(ERFC(dx),da,'ERFC(double)') + call c_d(DERFC(dx),da,'DERFC(double)') + + if ( fail ) call abort() + end + + subroutine failure(label) +c Report failure and set flag + character*(*) label + logical fail + common /flags/ fail + write(6,'(a,a,a)') 'Test ',label,' FAILED' + fail = .true. + end + + subroutine c_r(a,b,label) +c Check if REAL a equals b, and fail otherwise + real a, b + character*(*) label + if ( abs(a-b) .gt. 1.0e-5 ) then + call failure(label) + write(6,*) 'Got ',a,' expected ', b + end if + end + + subroutine c_d(a,b,label) +c Check if DOUBLE PRECISION a equals b, and fail otherwise + double precision a, b + character*(*) label + if ( abs(a-b) .gt. 1.0d-5 ) then + call failure(label) + write(6,*) 'Got ',a,' expected ', b + end if + end -- cgit v1.2.3
