These instructions are all implemented with fastmem support.
Currently loads with update are disabled due to an issue that I've yet to figure out.
I'm sure I'll figure that out later.
Currently supports only integer loadstores. Floating point loadstores will come later.
This system is semi based on the ARMv7 backpatching routine, where we need to initialize our backpatch routine sizes prior to actually using them so
we know we won't be overwriting any memory.
dcbz: just don't use GetPointer, that can't be right anyways
ppcanalyst: don't print "instruction hex 0" messages in MMU mode, where ISIs
are expected.
This hack is there for quite a long time, and lots of games crashes if it's disabled.
But it's still a hack, so it shouldn't be enabled hard coded. This commit create a new
ini option for this hack which is enabled by default.
Maybe some games does still run very fine without this hack.
This is a one instruction optimization for integer loadstores.
Makes sure to enable nop padding in some cases where a fault can still happen and cause us to overwrite other instructions that aren't meant to be.
Align our dispatcher to a page so we can jump to it with a ADRP+BR pair instead of ADRP+ADD+BR.
Also make sure to save /all/ of our callee saved registers that we are supposed to save.
Requires PR #1705 prior to merging.
Adds the ability to flush the cache and maintain state.
Adds the BindToRegister ability.
Sorts register usage as callee saved used first, reduces dumping pressure when jumping to external routines/interpreter.
Adds a function to store a register, for use when flushing a register that won't be used during the rest of a block.
Unfortunately the map files in American Mensa Academy don't correspond to the release version.
But at least now if other games use those map files we will be able to load them.
Fixes#7917
The first memset was clearing the delicate bits of the std::string
in the struct, causing segfaults.
I also removed the rest of the memsets because they were paranoid,
unneeded and waseful. We shouldn't be managing the ssl libraries
structs for it.
I checked and the ssl library's functions were already memsetting
those structs as needed.
Even in games that require MMU mode, loads outside the area specified by
the BAT are rare, so fastmem is a substantial improvement.
All of the interesting changes are in the backpatch handler, to make it
generate DSI exceptions correctly.
