HI again,
Do we have any consencus how to handle the OMP directives in the frontends ?
I have been looking at the fortran frontend and the c parser in gcc, ( I
suppose we have updated our source tree ? ).
From the discusions lately I have understood that basicly we would like to
bring the OMP stuff into tree-ssa whithout much modification, simply doing a
syntax and context check but not generating something interesting.
Diego's dissertation ( I think it was a dissertation ) seem's like a strong
argument to handle the parallellisation in the 'middle end' aka. tree-ssa.
I have also looked a bit at intels omp compiler, and the question remains if
our approach of 'doing everything in the lib' will be able to match the kind of
overhead their solution gives.
So how do we progress ?
I was thinking of generating a small set of patches agains the fortran
frontend and the C parser, but it will be hard to get started until we know
where to do most of the processing. My opinion at the moment is to get it all
through the frontend, and don't give a damn about anything else since this is a
primary problem to solve.
This doesn't exclude that work can be done on the lib, and other phases it
only relates to the info.
However this totally leaves out ANY implementation details, which are
postponed to a later stage, thus there is nothing to hinder us in progressing.
So if anything we should make some testcases for the #pragmas and !$OMP
directives for C and fortran.
Any opinions ?
