The main improvement is for placing the code sections in PC segment for RAM startup. This unleashes Harvard for caches that gives near-to-internal-SRAM performance for external DDRAM. The attached patch (and the one that follows) also contain changes from attachment #1945 described in comment #18 Ilija. -- Configure bugmail: http://bugs.ecos.sourceware.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
