Bug ID: 108175
Summary: Target macros missing in gfortran with -cpp (C
preprocessor)
Product: gcc
Version: 13.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: burnus at gcc dot gnu.org
Target Milestone: ---
Compare
touch foo.c; gcc -E -cpp -dM foo.c
foo.F90; gfortran -E -cpp -dM foo.F90
And note that in the C case, there are several target macros defined, e.g. on
my system:
__amd64, __amd64__, __ELF__, __linux, __linux__, linux, __unix, __unix__, unix
__x86_64, __x86_64__
EXPECTED: Those are also available with gfortran – as they are very useful to
generate some conditional code, especially for systems like Windows or embedded
systems where certains things don't work or work differently.
