http://codereview.chromium.org/501170/diff/1/3#newcode738 src/ia32/macro-assembler-ia32.cc:738: UpdateAllocationTopHelper(result_end, scratch); I assume the order was changed here generate instructions with better scheduling (it would be nice if the change log said more about why changes were made...) The result is probably going to be used almost immediately. On a previous compiler I found using lea instead of or_ was faster because the address generation unit has faster bypass. http://codereview.chromium.org/501170 -- v8-dev mailing list [email protected] http://groups.google.com/group/v8-dev
