Hello world,
the attached patch makes -Ofast honor -fmax-stack-var-size, and adjusts
the documentation in the gcc and fortran directories accordingly.
This is done to alleviate PR 68829, to make it possible to run -Ofast
with less stack usage. I have also taken the opportunity to make
it a bit clearer what -fstack-arrays actually does.
I intend to close PR 68829 once this is committed.
Regression-tested, plus doc changes tested with "make pdf" and
"make dvi".
OK for trunk for
- the fortran subdirectory changes
- the gcc doc changes (if the one above is approved)
?
Regards
Thomas
