Bug ID: 120493
Summary: 2 different functions to get call RTX from CALL_INSN
Product: gcc
Version: 16.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: other
Assignee: unassigned at gcc dot gnu.org
Reporter: hjl.tools at gmail dot com
Target Milestone: ---
There are
/* Return the CALL in X if there is one. */
rtx
get_call_rtx_from (const rtx_insn *insn)
{
rtx x = PATTERN (insn);
if (GET_CODE (x) == PARALLEL)
x = XVECEXP (x, 0, 0);
if (GET_CODE (x) == SET)
x = SET_SRC (x);
if (GET_CODE (x) == CALL && MEM_P (XEXP (x, 0)))
return x;
return NULL_RTX;
}
and
/* Given a CALL_INSN, find and return the nested CALL. */
static rtx
call_from_call_insn (rtx_call_insn *insn)
{
rtx x;
gcc_assert (CALL_P (insn));
x = PATTERN (insn);
while (GET_CODE (x) != CALL)
{
switch (GET_CODE (x))
{
default:
gcc_unreachable ();
case COND_EXEC:
x = COND_EXEC_CODE (x);
break;
case PARALLEL:
x = XVECEXP (x, 0, 0);
break;
case SET:
x = XEXP (x, 1);
break;
}
}
return x;
}
Can we have only one?
