linux: look for legacy ~/.reicast and ~/.reicast/data
else look for ~/.config/flycast and ~/.local/share/flycast
and ~/.config/reicast and ~/.local/share/reicast
(defaults to flycast)
look for bios files in home folder and data folders (android, windows
,macos), then in game folder.
on linux, search in /usr/share/flycast and /usr/local/share/flycast and
legacy locations
All ram pages containing code are write protected. In that case, no need
for block checks. Memory reads in the same block(s) can also be executed
at compile time and the results propagated as constants.
When a write is detected in a protected area, the corresponding blocks
are discarded and recompiled using traditional (slow) block checks.
Backported the blkmap code finding change from upstream.
Use smart pointers for block management to avoid reference issues.
Added WriteAfterWrite ssa pass
Fixed crash in ssa ConstProp pass when op list is modified
pass exception pc in x2 reg for both slow/fast paths
infer the op type and size from the armv8 op encoding
rewrite doesn't need access to the block anymore
add support for some imm args
native implementation of negc and xtrct for x64 and arm64
rec-arm64: pass exception pc in w27 instead of sh4 context
inline mmu_intruction_translation() and clean up
Tested: Both with and without the feature, works only for x64 CPUs for
now, but supported in both windows and linux (see vmem implementation
for it, using mem-mapped files).
Linked them both toghether since you can't really define one and
not the other (plus Linux honors one windows the other in some
cases).
More refactoring on this area to follow.
Simplifies having implementation on platform separated files, which is a
pain for platforms which are not Windows but not Linux either (and yet
support pthreads).
Some minor cleanup here and there while we are at it.
generates direct vmem read & write accesses
trap sigsegv and rewrite using slow path
add w29 to allocatable registers
get rid of literals and use pc-rel branching
minor optimizations and cleanup
