The tests gcc.dg/sibcall-3.c and gcc.dg/sibcall-4.c (execution tests)
fail on hppa64-hp-hpux11.{11,23}. Not a regression relative to 3.4.x.

Hmm, for sibcall-3.c (likewise for 4) we have the following comment:
This test is xfailed on targets without sibcall patterns
(except targets where the test does not work due to the return address
not saved on the regular stack).
And in pa.c, we find this:
/* Sibcalls are not ok because the arg pointer register is not a fixed
register. This prevents the sibcall optimization from occurring. In
addition, there are problems with stub placement using GNU ld. This
is because a normal sibcall branch uses a 17-bit relocation while
a regular call branch uses a 22-bit relocation. As a result, more
care needs to be taken in the placement of long-branch stubs. */
if (TARGET_64BIT)
return false;
So these tests should be just xfailed.

The stub placement issues in GNU ld still haven't been fixed.

The testcase is now xfailed but now it is missed optimization so suspending untill binutils is fixed.
