Hi all,
Say I want to print env->some_field in vl.c. I #include "dyngen-exec.h"
in vl.c, but got compilation error immediately.
/tmp/chenwj/qemu/dyngen-exec.h:64:10: error: attempt to use poisoned
"CPUArchState"
/tmp/chenwj/qemu/dyngen-exec.h:64:23: error: expected '=', ',', ';', 'asm' or
'__attribute__' before '*' token
/tmp/chenwj/qemu/dyngen-exec.h:64:24: error: attempt to use poisoned "env"
After googling, I figure out QEMU poison some identifiers which cannot be used
in target indenpent code. Although we can get some_field by the following way,
int some_field = &env->some_field;
but it's not very convenient if we have many field of CPUState want to access.
Is
there a better way to do so? Thanks!
Regards,
chenwj
