NORETURN void anonymous_namespace{irrevocability.cpp}::abort_irrevocable

(

Handler for abort attempts while irrevocable. Useful for trapping problems early.

custom commit for irrevocable transactions

stm::scope_t* anonymous_namespace{irrevocability.cpp}::rollback_irrevocable

(

STM_ROLLBACK_SIG(,,,)

)

Handler for rollback attempts while irrevocable. Useful for trapping problems early.

NB: For whatever reason a 'using stm::scope_t' triggers an ICE in Mac OS X's default gcc-4.2.1. It's fine if we use the fully qualified namespace here.

Here is the caller graph for this function:

void anonymous_namespace{irrevocability.cpp}::set_irrevocable_barriers ( TxThread &  tx )

inline

Sets all of the barriers to be irrevocable, except tmbegin.

Here is the caller graph for this function:

void anonymous_namespace{irrevocability.cpp}::unset_irrevocable_barriers ( TxThread &  tx )

inline

Resets all of the barriers to be the curr_policy bariers, except for tmabort which reverts to the one we saved, and tmbegin which should be done manually in the caller.

Variable Documentation

AbortHandler anonymous_namespace{irrevocability.cpp}::old_abort_handler = NULL

The abort handler is set during sys_init. We overwrite it with abort_irrevocable when a transaction becomes irrevocable, and we save the old one here so we can restore it during commit.
