[Bug target/40473] New: -mno-sched-prolog breaks function parameter debug location lists

[amodra at bigpond dot net dot au]

/* When compiled with -g -O -mno-sched-prolog, the debug info location
   lists for p1 and p2 do not cover the start of f.  There are other
   inaccuracies, but not covering the start of the function is specific
   to -nno-sched-prolog.  */
int f (int p1, int p2)
{
  extern int bar (int);
  int x, y;
  for (x = p1, y = 0; x < p2; x++)
    y += bar (x);
  return y;

This option should just be removed.

Created an attachment (id=18016)
 --> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=18016&action=view)
patch proposal

Actually, it doesn't look all that hard to fix.  The attached patch is a little
horrible in that it doesn't use the normal method of insert_insn_on_edge(),
commit_edge_insertions(), but we are too late for that.  I tried, and found
verify_flow_info() in commit_edge_insertions() was bombing on stuff already
present.  Patch currently bootstrapping with BOOT_CFLAGS="-g -O2
-mno-sched-prolog".
