/qemu-git-2009_09_16/tcg/arm/tcg-target.c:773: tcg fatal error
- how to reproduce the issue
This one's harder - I'm running an x86 gnome application on an ARM
system. I'm not sure exactly what it was doing when the abort happened.
Questions:
* The function in tcp-target.c seems complete, but it has
#if 1
tcg_abort();
#endif
which implies it's not complete or maybe just untested?
* How can I gather more information about what was going on
at the time to aid in fixing this?
Your problem is probably due to generated code being too far from
the helper functions (the helper functions can be thought of as a
library).
Could please try to replace the tcg_abort() on line 773 with these
two lines?
tcg_out_movi32(s, cond, TCG_REG_R8, val);
tcg_out32(s, (cond<< 28) | 0x012fff30 | TCG_REG_R8); /* blx r8 */
I didn't test it, so you'll be my guinea pig :-)
