RSDuck aa430608e7 support allocating more registers for aarch64 JIT 
also some minor fixes for the x64 JIT as well
 2021-06-29 22:25:43 +02:00
RSDuck 436b3c4c1d update copyright year and add missing GPL headers 2021-03-12 20:07:40 +01:00
RSDuck 78839f862e JIT fixes 
- fix fastmem problems on linux
- small fix memory leak
- SlowWrite functions always take in a 32-bit variable so that the C compiler knows that the values aren't necessary zero extended
- a few other stylistic things
- handle SIGBUS as well (for macos)

Random minor fixes (#757) 
* Fix incorrect/questionable assert() usage

Originally reported by https://lgtm.com/projects/g/Arisotura/melonDS/?mode=tree&ruleFocus=2159000700,
but also includes a bunch of other fixes.

* Fix some `printf` warnings

Rule https://lgtm.com/projects/g/Arisotura/melonDS/?mode=tree&ruleFocus=2160310550

* Remove useless check

It is never passed thanks to `if (num_in < 1) {...; return}` before
Rule https://lgtm.com/projects/g/Arisotura/melonDS/?mode=tree&ruleFocus=2154840804

* Add missing header guard, rename other to avoid conflicts

Rule https://lgtm.com/projects/g/Arisotura/melonDS/?mode=tree&ruleFocus=2163210746

* Make DSi_SDDevice destructor virtual

Rule https://lgtm.com/projects/g/Arisotura/melonDS/?mode=tree&ruleFocus=2158670642

* Use thread-safe localtime_r, assign `time` result directly

Rule https://lgtm.com/projects/g/Arisotura/melonDS/?mode=tree&ruleFocus=2154840805

* Fix MinGW build

It needs _POSIX_THREAD_SAFE_FUNCTIONS to export `localtime_r`

- 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
