Hi Andreas,

I can live with that, but it seems a little strange - is there a
way to check for an error message that is not associated with
a particular line number?
Use zero as the line number (like gcc.dg/Wfatal-2.c).
I tried to do that, but there is still a mystery. My test
case now is
! { dg-do compile }
! { dg-options "-ffrontend-optimize -fexternal-blas64" }
! { dg-require-effective-target ilp32 }
! { dg-error "-fexternal-blas64 requires a 64-bit system"
"matmul_blas_4.f90" { target *-*-* } 0 }
! { dg-error "compilation terminated" "compilation terminated" { target
*-*-* } 0 }
! PR 121161 - do not use -fexternal-blas64 with a 32-bit system.
subroutine foo(a,b,c,n)
implicit none
integer(kind=8) :: n
real, dimension(n,n) :: a, b, c
c = matmul(a,b)
end subroutine foo
and I get, when running
make check-fortran RUNTESTFLAGS="--target_board=unix\{-m32\}
dg.exp=gfortran.dg/matmul_blas_4.f90"
f951: Fatal Error: -fexternal-blas64 requires a 64-bit system
compilation terminated.
compiler exited with status 1
PASS: gfortran.dg/matmul_blas_4.f90 -O matmul_blas_4.f90 at line 4
(test for errors, line )
FAIL: gfortran.dg/matmul_blas_4.f90 -O compilation terminated at line
5 (test for errors, line )
and
FAIL: gfortran.dg/matmul_blas_4.f90 -O (test for excess errors)
Excess errors:
compilation terminated.
There is no typo in the "compilation terminated" regexp because I copied
it from the compiler output :-)
Anything else I might be doing wrong?
Best regards
Thomas
