Subject: call_insns in RTX form--two questions
Date: Tue, 30 May 2006 04:09:03 +0000
The first question is: If I want to find a BB that containing a specific
function call (say 'foo'), is there an easy way in the RTX level?
The second one is: how can i get the order of different call foo in the
final assembly code. Can I get it by dumping some information, say the
order of the instruction link list, in RTL representation?
Many thanks,
Sean

FOR_EACH_BB(bb){
for (cur_insn = BB_HEAD (bb); cur_insn != NEXT_INSN (BB_END (bb));
cur_insn = NEXT_INSN (cur_insn)){
if (GET_CODE (cur_insn)==CALL_INSN && /*test if the call is 'foo'*/){
//Question (1)
fprintf ("this is %dth call foo instruction \n", /*some dump*/);
//Question (2)
}
}
}
