[Qemu-devel] Question about debugging binary translator (TCG beckend) in system mode |

Hello all,
I have written my own TCG code generator (translate TCG to i386). It works well in user mode (pass every benchmark). However, there
is something error in system mode:
Host - x86-64, Configuration - --target-list=i386-softmmu --enable-debug --disable-kvm
------------------------------------------------------------------------------------
| minix2.04 | small-ffs (NetBSD)
------------------------------------------------------------------------------------
single step | correct | correct
------------------------------------------------------------------------------------
non-single step | correct | init panic(restart)
------------------------------------------------------------------------------------
(I have comment tb_add_jump of cpu-exec:cpu_exec to disable block chaining)
I dump the exec but there is so much logs to debug. I am wondering to know how TCG codegen developer debug during development ??
thanks a lot
Mitnick
