\doxysubsection{Detailed Description}
|
|
jcc rewrite pass which rewrites rip relative jcc\textquotesingle{}s so that they are position independent.
|
|
|
|
given the following code\+: \begin{DoxyVerb}jnz label1
|
|
; other code goes here
|
|
\end{DoxyVerb}
|
|
label1\+: ; more code here
|
|
|
|
the jnz instruction will be rewritten so that the following code is generated\+: \begin{DoxyVerb}jnz br2
|
|
\end{DoxyVerb}
|
|
br1\+: jmp \mbox{[}rip\mbox{]} ; address after this instruction contains the address ; of the instruction after the jcc. br2\+: jmp \mbox{[}rip\mbox{]} ; address after this instruction contains the address of where ; branch 2 is located.
|
|
|
|
its important to note that other passes will encrypt (transform) the address of the next instruction. There is actually no jmp \mbox{[}rip\mbox{]} either, push/ret is used.
