Hi All!
Is there any particular reason that matmul* modules from libgfortran
are compiled with -O2 -ftree-vectorize?
I see some regressions on Atom processor after r202980
(http://gcc.gnu.org/ml/gcc-cvs/2013-09/msg00846.html)
Why not just use O3 for those modules?
Igor,
It helps (:-) to send questions about gfortran and its run time library
libgfortran cc'd to fortran@gcc.gnu.org, because not every GNU Fortran
maintainer reads gcc@gcc.gnu.org ....
Kind regards,
