[Bug tree-optimization/21004] New: [4.1 Regression] gcc.dg/builtins-53.c fails

[jsm28 at gcc dot gnu dot org]

The new test gcc.dg/builtins-53.c fails on hppa{2.0w,64}-hp-hpux11.{11,23}:

builtins-53.c: In function 'test1f':
builtins-53.c:46: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.

This is a regression from 4.0.

gcc-testresults also shows it failing on mips-sgi-irix6.5,
powerpc-unknown-eabispe and i686-pc-cygwin.  I don't know whether this is the
same failure.

I susupect the bug to be in expand_builtin_int_roundingfn(). It looks that 

  tmp = gen_reg_rtx(floatmode);

is needed before

  tmp = expand_builtin_mathfn (exp, NULL_RTX, NULL_RTX);

It is somehow annoying fact that everything works OK on i686-pc-linux-gnu.
