byuu says:
Note: balanced/performance profiles still broken, sorry.
Changelog:
- added nall/GNUmakefile unique() function; used on linking phase of
higan
- added nall/unique_pointer
- target-tomoko and {System}::Video updated to use
unique_pointer<ClassName> instead of ClassName* [1]
- locate() updated to search multiple paths [2]
- GB: pass gekkio's if_ie_registers and boot_hwio-G test ROMs
- FC, GB, GBA: merge video/ into the PPU cores
- ruby: fixed ~AudioXAudio2() typo
[1] I expected this to cause new crashes on exit due to changing the
order of destruction of objects (and deleting things that weren't
deleted before), but ... so far, so good. I guess we'll see what crops
up, especially on OS X (which is already crashing for unknown reasons on
exit.)
[2] right now, the search paths are: programpath(), {configpath(),
"higan/"}, {localpath(), "higan/"}; but we can add as many more as we
want, and we can also add platform-specific versions.
