Function Documentation
◆ build_tm_abort_call()
Build a GENERIC tree for a user abort. This is called by front ends while transforming the __tm_abort statement.
References AR_OUTERABORT, AR_USERABORT, build_call_expr_loc(), build_int_cst(), builtin_decl_explicit(), and integer_type_node.
◆ compute_transaction_bits()
|
extern |
Set the IN_TRANSACTION for all gimple statements that appear in a transaction.

Referenced by tree_ssa_lim_initialize().
◆ is_tm_ending()
Return true if STMT is a built in function call that "ends" a transaction.
References gimple_call_fndecl(), is_tm_ending_fndecl(), and NULL_TREE.
Referenced by merge_stmts_p().
◆ is_tm_ending_fndecl()
Return true for built in functions that "end" a transaction.

◆ is_tm_may_cancel_outer()
Return true if X has been marked TRANSACTION_MAY_CANCEL_OUTER.
References get_attrs_for(), lookup_attribute(), and NULL.
Referenced by diagnose_tm_1(), and diagnose_tm_blocks().
◆ is_tm_pure()
|
extern |
Return true if X has been marked TM_PURE.
References ECF_TM_PURE, flags_from_decl_or_type(), TREE_CODE, TREE_TYPE, and TYPE_P.
Referenced by can_inline_edge_p(), ipa_tm_execute(), and is_tm_safe_or_pure().
◆ is_tm_safe()
|
extern |
Return true if X has been marked TM_SAFE.
References get_attrs_for(), and lookup_attribute().
Referenced by diagnose_tm_blocks(), expand_call_tm(), ipa_tm_execute(), ipa_tm_insert_gettmclone_call(), ipa_tm_mayenterirr_function(), ipa_tm_scan_irr_block(), and is_tm_safe_or_pure().
◆ record_tm_replacement()
References hash_table< Descriptor, Lazy, Allocator >::create_ggc(), DECL_UNINLINABLE, ggc_alloc(), NULL, and tm_wrap_map.
Referenced by tm_malloc_replacement().
◆ tm_malloc_replacement()
|
extern |
When appropriate, record TM replacement for memory allocation functions. FROM is the FNDECL to wrap.
