Bug ID: 59604
Summary: Constant comparisons with -fno-range-check and
int(z'...')
Product: gcc
Version: 4.9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: tkoenig at gcc dot gnu.org
Trying out a fix for PR 58003, I found that the following program was of the
opinion that -1 does not equal -1:
ig25@linux-fd1f:~/Krempel/NoRange> cat bar.f90
program test
use iso_fortran_env
implicit none
integer, parameter :: wt = int32
print *, int(z'FFFFFFFF',wt)
print *, int(z'FFFFFFFF',wt) /= -1
end program test
ig25@linux-fd1f:~/Krempel/NoRange> gfortran -fno-range-check bar.f90
ig25@linux-fd1f:~/Krempel/NoRange> ./a.out
-1
T
