Bug #: 56382
Summary: FAIL: gcc.c-torture/compile/pr55921.c (internal
compiler error)
Classification: Unclassified
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: middle-end
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: danglin@gcc.gnu.org
Host: hppa64-hp-hpux11.11
Target: hppa64-hp-hpux11.11
Build: hppa64-hp-hpux11.11
This is a problem extracting the first subreg from a SCmode value. Thia
occurs during reload after the point where pseudos can be created but we
need a pseudo to extract the subreg. The problem is SCmode is the same
size as DImode on this target, so the subreg can't be extracted by a move.
I marked this a middle-end bug as the documentation indicates that complex
values are handled by it.

Patch
I tried the above changes to expmed.c but this
approach eventually reaches a gcc_unreacheable
dead end.
