Bug ID: 125416
Summary: man page: -fcoarray=shared not documented
Product: gcc
Version: 17.0
Status: UNCONFIRMED
Keywords: documentation
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: burnus at gcc dot gnu.org
CC: jvdelisle at gcc dot gnu.org
Target Milestone: ---
-fcoarray=shared must be document in the man page
* * *
https://gcc.gnu.org/onlinedocs/gfortran/Code-Gen-Options.html#index-fcoarray
lacks the new 'shared'
* * *
fortran/invoke.texi has:
-fcoarray=<none|single|lib> -fexternal-blas -fexternal-blas64 -ff2c
...
@opindex fcoarray
@cindex coarrays
@item -fcoarray=@var{<keyword>}
@table @asis
@item @samp{none}
Disable coarray support; using coarray declarations and image-control
statements produces a compile-time error. (Default)
@item @samp{single}
Single-image mode, i.e. @code{num_images()} is always one.
@item @samp{lib}
Library-based coarray parallelization; a suitable GNU Fortran coarray
library such as @url{http://opencoarrays.org} needs to be linked.
Alternatively, GCC's @code{libcaf_single} library can be linked,
albeit it only supports a single image.
