Bug ID: 89431
Summary: CPP integer macros not defined
Product: gcc
Version: 9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: mark.eggleston at codethink dot com
Target Milestone: ---
The integer macros specified in the "Preprocessing and conditional compilation"
section of the manual do not exist. The real macros on the other hand do.
On x86_64:
program test
use iso_fortran_env
implicit none
write(*,*) integer_kinds
#ifdef __GFC_INTEGER_1__
write(*,*) "__GFC_INTEGER_1__ defined"
#else
write(*,*) "__GFC_INTEGER_1__ undefined"
#endif
#ifdef __GFC_INTEGER_2__
write(*,*) "__GFC_INTEGER_2__ defined"
#else
write(*,*) "__GFC_INTEGER_2__ undefined"
#endif
#ifdef __GFC_INTEGER_8__
write(*,*) "__GFC_INTEGER_8__ defined"
#else
write(*,*) "__GFC_INTEGER_8__ undefined"
#endif
#ifdef __GFC_INTEGER_16__
write(*,*) "__GFC_INTEGER_16__ defined"
#else
write(*,*) "__GFC_INTEGER_16__ undefined"
#endif
write(*,*) real_kinds
#ifdef __GFC_REAL_10__
write(*,*) "__GFC_REAL_10__ defined"
#else
write(*,*) "__GFC_REAL_10__ undefined"
#endif
#ifdef __GFC_REAL_10__
write(*,*) "__GFC_REAL_16__ defined"
#else
write(*,*) "__GFC_REAL_16__ undefined"
#endif
end program
produces
1 2 4 8 16
__GFC_INTEGER_1__ undefined
__GFC_INTEGER_2__ undefined
__GFC_INTEGER_8__ undefined
__GFC_INTEGER_16__ undefined
4 8 10 16
__GFC_REAL_10__ defined
__GFC_REAL_16__ defined
Also present on 8.2 and 7.4
