JSRF appears to have it disabled despite other optimizations. Even if
it was enabled, anyways, we'd still be decompiling the post-inlining
functions and wouldn't want any further inlining to take place (we want
the compiler to compile each function the way we write it).
The change in the previous commit was a silly case of not thinking
things through, not realizing that the .data range moved to Core.obj was
nowhere near the beginning of the section as it should be. g_game has
been moved back into Jet2.obj (time will tell if this is correct) and a
missed data strucure at the beginning of .data (where it ought to be)
now makes up Core.obj's .data portion.
objdiff assumes that all symbols in executable memory sections are code,
which led to misbehaviour due to .rdata and .data being marked as
executable in JSRF. We now set these sections to non-executable in
Ghidra to work around this.
We can now create a fresh Ghidra project, import the JSRF executable
into it, import symbols into it, delink object files from it, and then
decompile with objdiff. Just needs some documentation.
If you've cloned this repository on Windows, you have either a POSIX
environment or Git Bash and can run this script. It just needs to call
the right headless Ghidra script depending on the OS (which it now tries
to do).
