Currently this algo is kinda dumb and results in the forced recompilation of a - // lot of blocks before it decides to mark a 'busy' page as uncounted. There might be - // be a more clever approach that could streamline this process, by doing a first-pass - // test using the vtlb memory protection (without recompilation!) to reprotect a counted - // block. But unless a new also is relatively simple in implementation, it's probably - // not worth the effort (tests show that we have lots of recompiler memory to spare, and - // that the current amount of recompilation is fairly cheap). - - xADD(ptr16[&manual_page[inpage_ptr >> 12]], sz); - xJC( dyna_page_reset ); - - // note: clearcnt is measured per-page, not per-block! - DbgCon::WriteLn( "Manual block @ %08X : size=%3d page/offs=%05X/%03X inpgsz=%d clearcnt=%d", - params startpc, sz, inpage_ptr>>12, inpage_offs, inpage_sz, manual_counter[inpage_ptr >> 12] ); - } - else - { - DbgCon::Notice( "Uncounted Manual block @ %08X : size=%3d page/offs=%05X/%03X inpgsz=%d", - params startpc, sz, inpage_ptr>>12, inpage_offs, pgsz, inpage_sz ); - } - + DbgCon::Notice( "Uncounted Manual block @ %08X : size=%3d page/offs=%05X/%03X inpgsz=%d", + params startpc, sz, inpage_ptr>>12, inpage_offs, pgsz, inpage_sz ); } + } - inpage_ptr += pgsz; - inpage_sz -= pgsz; } // Finally: Generate x86 recompiled code!
