LoongArch: Subdivision symbol type, add SYMBOL_PCREL support.
1. Remove cModel type support other than normal.
2. The method for calling global functions changed from 'la.global + jirl' to 'bl'
when complied add '-fplt'.
gcc/ChangeLog:
* config/loongarch/constraints.md (a): Delete the constraint.
(b): A constant call not local address.
(h): Delete the constraint.
(t): Delete the constraint.
* config/loongarch/loongarch-opts.cc (loongarch_config_target):
Remove cModel type support other than normal.
* config/loongarch/loongarch-protos.h (enum loongarch_symbol_type):
Add new symbol type 'SYMBOL_PCREL', 'SYMBOL_TLS_IE' and 'SYMBOL_TLS_LE'.
(loongarch_split_symbol): Delete useless function declarations.
(loongarch_split_symbol_type): Delete useless function declarations.
* config/loongarch/loongarch.cc (enum loongarch_address_type):
Delete unnecessary comment information.
(loongarch_symbol_binds_local_p): Modified the judgment order of label
and symbol.
(loongarch_classify_symbol): Return symbol type. If symbol is a label,
or symbol is a local symbol return SYMBOL_PCREL. If is a tls symbol,
return SYMBOL_TLS. If is a not local symbol return SYMBOL_GOT_DISP.
(loongarch_symbolic_constant_p): Add handling of 'SYMBOL_TLS_IE'
'SYMBOL_TLS_LE' and 'SYMBOL_PCREL'.
(loongarch_symbol_insns): Add handling of 'SYMBOL_TLS_IE' 'SYMBOL_TLS_LE'
and 'SYMBOL_PCREL'.
(loongarch_address_insns): Sort code.
(loongarch_12bit_offset_address_p): Sort code.
(loongarch_14bit_shifted_offset_address_p): Sort code.
(loongarch_call_tls_get_addr): Sort code.
(loongarch_legitimize_tls_address): Sort code.
(loongarch_output_move): Remove schema support for cmodel other than normal.
(loongarch_memmodel_needs_release_fence): Sort code.
(loongarch_print_operand): Sort code.
* config/loongarch/loongarch.h (LARCH_U12BIT_OFFSET_P):
Rename to LARCH_12BIT_OFFSET_P.
(LARCH_12BIT_OFFSET_P): New macro.
* config/loongarch/loongarch.md: Reimplement the function call. Remove schema
support for cmodel other than normal.
* config/loongarch/predicates.md (is_const_call_weak_symbol): Delete this predicate.
(is_const_call_plt_symbol): Delete this predicate.
(is_const_call_global_noplt_symbol): Delete this predicate.
(is_const_call_no_local_symbol): New predicate, determines whether it is a local
symbol or label.
gcc/testsuite/ChangeLog:
* gcc.target/loongarch/func-call-1.c: New test.
* gcc.target/loongarch/func-call-2.c: New test.
* gcc.target/loongarch/func-call-3.c: New test.
* gcc.target/loongarch/func-call-4.c: New test.
