Julian Seward	5e6d4577de	Change the TT_FAST hash function for from "insn_address >> 2" to ... "insn_address >> 1". The former is appropriate for ARM code, where all insns are 4-sized and 4-aligned, but not for Thumb code, where the minimum size and alignment is 2. The old scheme happened to work for Thumb (indeed, any hash function would), but caused huge amounts of conflict misses in the fast cache for some programs. The change has been observed to reduce conflict misses by up to 100 times, and in some cases, improves performance significantly for Thumb code. Performance of ARM code is unchanged or possibly a bit worse. git-svn-id: svn://svn.valgrind.org/valgrind/trunk@11716	2011-04-28 14:58:15 +00:00
Julian Seward	de04801515	Merge from branches/THUMB: rack renaming of guest_R15 to guest_R15T. ... Also, add extra FPSCR masking for FPSCR invariant state sanity checks. git-svn-id: svn://svn.valgrind.org/valgrind/trunk@11279	2010-08-22 12:03:45 +00:00

Julian Seward	e9de458500	Merge from branches/ARM, all parts of the ARM-Linux port except for ... the changes to do with reading and using ELF and DWARF3 info. This breaks all targets except amd64-linux and x86-linux. git-svn-id: svn://svn.valgrind.org/valgrind/trunk@10982	2010-01-01 11:59:33 +00:00
