Disable jit on some modules on android to make koreader on Android more stable.
|
||||
|
||||
The strategy here is that we only use precious mcode memory (jitting)
|
||||
on deep loops like the several blitting methods in blitbuffer.lua and
|
||||
the pixel-copying methods in mupdf.lua. So that a small amount of mcode
|
||||
memory (64KB) allocated when koreader is launched in the android.lua
|
||||
is enough for the program and it won't need to jit other parts of lua
|
||||
code and thus won't allocate mcode memory any more which by our
|
||||
observation will be harder and harder as we run koreader.
