| source is a symbolic operand. Handle CONST_INT LO_SUM during PIC |
| generation. Simplify. |
| (define_split for symbolic_operand load): Do not accept a symbolic |
| operand that is a pic_label_operand. |
| (pic_load_label): Name this pattern. Mask least significant bits |
| and optimize when a simple label is within reach of an ldo. |
| (call, call_value): Emit new-style USE information for |
| pic_offset_table_rtx. Emit code for initialization of |
| hppa_save_pic_table_rtx and wrap it into push_topmost_sequence() |
| and pop_topmost_sequence() calls. |
| |
| * Various PA configuration cleanups. |
| * configure (hppa*-*-h[pi]ux): Use xm-pahpux.h and x-pa-hpux instead |
| of the redundant hiux files. Likewise for t-pa instead of t-pa-hpux. |

| * config/pa/x-pa-hiux: Delete. It's idential to x-pa-hpux. |
| * config/pa/x-pa (TAROUTOPTS): Delete. It was an HPUX host |

| moves, and then issue a blockage instruction. |

| as permitted by ANSI C. |
| |

| (movdf_push486, movxf_push486, movdi_push486): If an address is |
| based on the stack pointer, account for the stack pointer changing |
| due to the intermediate pushes generated. |

| functions with CSE following jumps, allocate EAX after EDX and |
| ECX, to allow the function return to be CSE'd, and perl 4.036's |
| perly.y to be compiled without aborting due to not being able to |
| find a spill register. |
| (movsf, movdf, movdi): Rewrite all patterns to provide effecient |
| memory to memory moves, including pushes for i386 and i486. Fixes |

| the more primitive generator functions instead of knowing how many |
| clobbers of match_scratchs they do. |

| values when creating insns, let the combiner create a push of a |

| declarations to allow memory<->memory moves with non-contigous |
| registers, so that reload don't abort if it can't make a DI |
| register. |
| (umulsidi3, mulsidi3): Don't allow pattern if -mno-wide-multiply. |
| (smultsi3_highpart, umultsi3_highpart): Add patterns to make |
| division by constants generate better code. |
