RSDuck	ec965c6014	improve nop handling and proper behaviour for LDM^ ... fixes dslinux	2020-06-16 11:57:49 +02:00
RSDuck	441869a105	integrate changes from ARM64 backend and more ... - better handle LDM/STM in reg alloc - unify Halted and IRQ in anticipation for branch inlining - literal optimisations can be disabled in gui - jit blocks follow simple returns - fix idle loop detection - break jit blocks on IRQ (fixes saving in Pokemon White)	2020-06-16 11:57:45 +02:00
RSDuck	9cf7780e46	decrease jit block cache address granularity ... fixes Dragon Quest IX move code with side effects out of assert, fixes release build (thanks to m4wx for this one) also remove some leftovers of jit pipelining	2020-06-16 11:56:45 +02:00
RSDuck	40b88ab05a	new block cache and much more... ... - more reliable code invalidation detection - blocks aren't stopped at any branch, but are being followed if possible to get larger blocks - idle loop recognition - optimised literal loads, load/store cycle counting and loads/stores from constant addresses	2020-06-16 11:56:36 +02:00
RSDuck	85680d6fe5	more fixes for flag optimisation ... + small cycle counting optimisation	2020-06-16 11:56:01 +02:00
RSDuck	d208f5909c	fixes for flag optimisation	2020-06-16 11:55:53 +02:00
RSDuck	f378458c10	optimise away unneeded flag sets ... - especially useful for thumb code and larger max block sizes - can still be improved upon	2020-06-16 11:55:44 +02:00
RSDuck	26ecf6bb3c	fix register alloc for half word loads ... fixes Mega Man Star Force 2 with cheat applied it probably used a pc relative load which were interpreted as branches	2020-06-16 11:54:51 +02:00
RSDuck	d74b15eecc	jit: fix thumb hi reg alu and mcr halt ... + mcr/mrc aren't always, msr_imm is never unk on ARM7	2020-06-16 11:54:06 +02:00

RSDuck	27cbc821b1	jit: thumb block transfer working ... also pc and sp relative loads and some refactoring	2020-06-16 11:53:08 +02:00
RSDuck	10e386fe50	JIT: most mem instructions working ... + branching	2020-06-16 11:53:08 +02:00
RSDuck	c692287eba	JIT: base ... all instructions are interpreted	2020-06-16 11:53:05 +02:00
