I have some heavy duty number crunching programs that need an optimizing
compiler on the SPARC10. Gcc speeds up my programs by a factor of 5
compared to the Sun cc but even the optimizations done by gcc aren't
enough. The GNU documentation is very explicit about the use of the
compiler for SPARC10. The README file says that gcc does not exploit the
superscalar mechanism of the SPARC10 and hence the performance is not very
good. Is there an optimizing compiler available (commercial or public
domain) that will do better than gcc? Has anyone implemented an
instruction scheduling mechanism for gcc to improve its performance on the
SPARC10? A response by email will be appreciated. Thanks.
