From 0d82948094d9a198e01aa95f64012bdedd5b6fc9 Mon Sep 17 00:00:00 2001 From: buzbee Date: Fri, 11 Oct 2013 15:24:55 -0700 Subject: 64-bit prep Preparation for 64-bit roll. o Eliminated storing pointers in 32-bit int slots in LIR. o General size reductions of common structures to reduce impact of doubled pointer sizes: - BasicBlock struct was 72 bytes, now is 48. - MIR struct was 72 bytes, now is 64. - RegLocation was 12 bytes, now is 8. o Generally replaced uses of BasicBlock* pointers with 16-bit Ids. o Replaced several doubly-linked lists with singly-linked to save one stored pointer per node. o We had quite a few uses of uintptr_t's that were a holdover from the JIT (which used pointers to mapped dex & actual code cache addresses rather than trace-relative offsets). Replaced those with uint32_t's. o Clean up handling of embedded data for switch tables and array data. o Miscellaneous cleanup. I anticipate one or two additional CLs to reduce the size of MIR and LIR structs.
