[PATCHv2 02/14] Consider real and protected mode in the dump file

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



On x86 'objdump' does not know which parts of the image are 16 bit code and
32 bit. As the default is 32 bit, it will output garbage from the 16 bit parts
(due to 16/32 bit ops are sharing the same opcodes).
