[Bug middle-end/36594] [4.4 Regression] multiple regressions on powerpc at rev.136976



------- Comment #3 from dje at gcc dot gnu dot org  2008-06-22 23:42 -------
Yes, similarly multiple regressions on AIX.  Reverting Honza's patch fixes it.

The failure on AIX is:

gcc/testsuite/gcc.c-torture/compile/20050122-2.c:11: internal 
compiler error: in copy_rtx, at rtl.c:314

rs6000.md restore_stack_nonlocal now receives a REG as operand[1] due to the
copy_to_reg change.  The pattern calls adjust_address_nv on the operand,
adjust_address_1 blindly dereferences the operand it thinks is a memref to
extract the address and applies copy_rtx() to the address.  copy_rtx receives
RTL with code UNKNOWN.  Fun and hilarity ensues.
