reload.c (operands_match_p): Handle rtvecs.
* reload.c (operands_match_p): Handle rtvecs.
* i386.c (legitimate_pic_address_disp_p): New.
(legitimate_address_p): Use it.
(legitimize_pic_address): Use unspecs to represent @GOT and @GOTOFF.
Handle constant pool symbols just like statics.
(emit_pic_move): Use Pmode not SImode for clarity.
(output_pic_addr_const) [SYMBOL_REF]: Remove @GOT and @GOTOFF hacks.
[UNSPEC]: New, handling what we killed above.
[PLUS]: Detect and abort on invalid symbol arithmetic.
* i386.h (CONSTANT_ADDRESS_P): Remove HIGH.
