#1235 [Pokemon white 2] Assertion failed when battling a trainer

Milestone: SVN past 0.9.8

Status: closed-fixed

Owner: CrazyMax

Labels: JIT (22)

Not Milestone: none

Priority: 5

Updated: 2013-10-15

When JIT is enabled, battling a trainer in pokemon white 2 results in

desmume: arm_jit.cpp:3930: void sync_r15(u32, bool, bool): assertion "!instr_uses_r15(opcode)" failed.

This happens just before the battle starts. Disabling the assertion seems to work, but I don't know how safe it is.

Unfortunately sourceforge won't let me attach files bigger than 256KB, so I have uploaded the savestate here:

Do you think it may be due to running it under linux? Because I cannot think of anything else: I tried rebuilding from a fresh svn tarball, without any extra options (just HAVE_JIT=1), and then I ran it with ./desmume --cpu-mode=1 and it still happens. I also tried different optimization levels (from -O0 to -O3). If from the savestate I go left and battle the first trainer I find I can reproduce this every time.

Just checked, and indeed under Windows it works without problems. So this seems a Linux-only bug

Broken for me too, Gentoo Linux with DeSmuME 0.9.9 svnr0 x64-JIT compiled from repo. Pokemon.Black.Version.EUR.NDS.

Crashes with CLI and --jit-size=1 as well.
