RE: TCG plugin : problem with call back in SW RISCV instructions

[BRICOUT Thaddée]

Hello, 

Thanks for your answer but I already fix my bug. 

I placed the insnPrt (from qemu_plugin_tb_get_insn) in argument for the call 
back function (udata) but it was modify before used. 

If I put the data I need in another variable, this one is not modify and the 
call back work normally.

Your plugin is only registering a memory callback, not an execution one 
(qemu_plugin_register_vcpu_insn_exec_cb).

Are you aware of the execlog plugin that is in contrib/plugins?
