Performance Ideas

This page will serve as a holding pen for half-baked performance ideas. Once they become more real, they will be migrated into issues we can track against the code.

• Harvest tricks from PowerPC Compiler Writer's Guide

• Consider peep-hole optimization of multiple double access sequences

li r0, offset-1
stdx value, r0, base_reg

• Exploit mmap of object space to limit 64bit addresses to 32bits

• Reserve scratch area in context? for double to integer backing store (instead of the stack)
