Test include header file with comment
A comment to the right of include line is not supported by the Flang front-end.
#include "simpleheader.fh" ! Simple header
[naromero@naromero-desktop bugs]$
/nfs/gce/projects/naromero-workspace/llvm-master/bin/flang -c
testheadercomments.F
/nfs/gce/projects/naromero-workspace/llvm-master/bin/f18: could not scan
testheadercomments.F
testheadercomments.F:2:10: error: #include: expected name of file to include
#include "simpleheader.fh" ! Simple header
^^^^^^^^^^^^^^^^^
I am not sure if this is part of the Fortran language standard or not, but
ifort supports it without warnings. PGI and Gfortran support it, but issue a
warning.
[naromero@naromero-desktop bugs]$ pgfortran -c testheadercomments.F
PGF90-W-0951-Extraneous tokens ignored following # directive
(testheadercomments.F: 2)
GFortran
[naromero@naromero-desktop bugs]$ gfortran -c testheadercomments.F
testheadercomments.F:2:0:
#include "simpleheader.fh" ! Simple header
Warning: extra tokens at end of #include directive
I am not sure if this is part of the Fortran standard or not.
