Bug ID: 109659
Summary: gcc_builtin module for gfortran
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: enhancement
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: tkoenig at gcc dot gnu.org
Target Milestone: ---
There are lots of useful builtin functions in gcc which Fortran currently
does not have access to. Just think of checking for integer overflow,
which gcc offers as __builtin_add_overflow().
Extending the language with new intrinsics is probably not a good idea
because, if things like that are later taken up, they will be made
incompatible by the committee.
So, I propose to add an intrinsic gcc_builtin module, which could then
export Fortran versions of those builtin functions that we think are
useful.
Thought? Comments?
