Bug ID: 82130
Summary: stringification (#) in traditional mode
Product: gcc
Version: 7.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: preprocessor
Assignee: unassigned at gcc dot gnu.org
Reporter: janus at gcc dot gnu.org
Target Milestone: ---
I noticed that cpp does not seem to support stringification in traditional
mode.
Simple Fortran test:
#define _ASSERT_(expr) if (.not. (expr)) print *, #expr
program test
logical :: check = .false.
_ASSERT_(check)
end
cpp in standard mode does the expected thing, namely translate the _ASSERT_
line into:
if (.not. (check)) print *, "check"
(which is valid Fortran code). But with -traditional I get:
if (.not. (check)) print *, #check
That's a shame because it makes stringification unusable with gfortran. Is is
feasible to add support for stringification in traditional mode?
