pub fn patch_setcc(original: &[u8], value: bool) -> Result<Vec<u8>>Expand description
Rewrite a SETcc instruction so it unconditionally writes
value as u8 to its destination operand.
original is the verbatim instruction byte sequence (typically
3 bytes for setcc r/m8 or 4 bytes with a REX prefix; longer for
memory operands with SIB / displacement). The returned vector is
the same length and contains the equivalent MOV r/m8, imm8.
ยงErrors
Returns Error::Parse if the byte sequence does not look like
a SETcc encoding (no 0F 9x opcode pair, REG field of ModR/M not
/0, or the buffer is too short).
