* reg-stack.c (reg_to_stack): Large models don't allow NAN to be
loaded for constant large models. Non-large 64bit PIC can do.
* i386.h (CASE_VECTOR_MODE): Large PIC cases are 64bit.
* cmodel.h: Add LARGE PIC.
* i386.md (UNSPEC_PLTOFF): New.
(UNSPEC_SET_RIP, UNSPEC_SET_GOT_OFFSET): New; renumber other unspecs as
needed.
(*call_1_rex64): Disable for large models.
(*call_1_rex64_large): New.
(*call_value_1_rex64): Disable for large models.
(*call_value_1_rex64_large): New.
(set_rip_rex4): New.
(set_got_offset_rex64): New.
* predicates.md (constant_call_address_operand): For large model
constant calls are not possible.
* i386-protos.h (construct_plt_address): Declare.
* i386.c (override_options): Accept large models.
(ix86_expand_prologue): Expand large PIC GOT pointer load.
(legitimate_constant_p): Add new UNSPECs.
(legitimate_pic_operand_p): Likewise.
(legitimate_pic_address_disp_p): Disallow local symbols for large PICs.
(legitimize_pic_address): Do easy RIP relative way for TLS only for
non-large model.
(output_pic_addr_const): Add PLTOFF.
(ix86_output_addr_diff_elt): Output 64bit tables when needed.
(ix86_expand_move): Legitimize pic address when in PIC mode.
(construct_plt_address): New function.
(ix86_expand_call): Offload the address to register and use GOT pointer
for large model.
* invoke.texi (mcmodel=large): Update documentation.
