Series target/i386: make decoding entirely table based | expand

Commit Message

Paolo Bonzini June 20, 2024, 9:54 a.m. UTC 
Now all decoding has been done before any code generation.
There is no need anymore to save and restore cc_op* and
pc_save but, for the time being, assert that this is indeed
the case.
