<DIV>Hi, </DIV>
<DIV> </DIV>
<DIV>
<DIV style="TEXT-INDENT: 2em">I have a llvm pass in hand written by other
people. There are following statements that I couldn't understand:</DIV>

<DIV style="TEXT-INDENT: 2em">

<DIV> return ...;</DIV>
<DIV> }</DIV>

<DIV> // Calls to external functions</DIV>...</DIV></DIV>
<DIV

<DIV style="TEXT-INDENT: 2em"> </DIV>
<DIV style="TEXT-INDENT: 2em">My question is:</DIV>
<DIV style="TEXT-INDENT: 2em"> </DIV>
<DIV style="TEXT-INDENT: 2em">What's the definitions of internal functions and
external functions? In c, internal functions is functions that it is only called
in the file where it defines using keyword "static", external functions is
functions that can be called by other files, defining using keyword
"external". Are these definitions identical with the
definitions in llvm? </DIV>
<DIV style="TEXT-INDENT: 2em"> </DIV>
<DIV style="TEXT-INDENT: 2em">Thank you very much.</DIV>
<DIV style="TEXT-INDENT: 2em"> </DIV>
