Hi, When compiling a simple matrix dot product example on both alpha & ia64 using -O3 and -fmodulo-sched options, I am unable to find a software pipelined loop in the generated assembly. I think the advanced optimizations dont seem to occur anymore in Gcc although they are documented in the manuals. Is this a known issue ? I think that apart from powerpc, no other architecture is optimized properly by gcc. This is probably due to the separate contrib tree from IBM vs the rest of the world. The IBM contrib works whereas later contribs dont. The IBM contrib from Haifa works but I am unaware as to why newer contribs seem to fail ! None of the selective sched, modulo sched contributions show up at all! Can anyone help? Sincerely, Seima Rao.
