Chinoune closed this and other PRs that s/he submitted because of a temper tantrum. S/He's upset that https://gcc.gnu.org/pipermail/gcc-bugs/2021-January/724765.html was closed as INVALID because the behavior documented in the manual does not meet his/her expectations. S/He refuses to accept that gfortran has selected processor-dependent behavior that does is different than Intel Fortran. Note Intel Fortran documents it choice, but does not conform to its own documentation. Just open a new PR with a Depends On reference to this PR. ^ permalink raw reply [flat|nested] 6+ messages in thread
