Bug ID: 67785
Summary: irrevocable-3.c: transaction_callable does nothing on
external declaration
Product: gcc
Version: 6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: middle-end
Assignee: unassigned at gcc dot gnu.org
Reporter: jason at gcc dot gnu.org
CC: aldyh at gcc dot gnu.org, rth at gcc dot gnu.org,
torvald at gcc dot gnu.org
Target Milestone: ---
In gcc.dg/tm/irrevocable-3.c:
extern void bar(void) __attribute__((transaction_callable));
void
foo()
{
__transaction_relaxed {
bar();
}
}
The transaction_callable attribute seems to have no effect; the transaction
goes irrevocable and calls the non-transaction entry point for bar whether or
not it is present.
Shouldn't the transaction call the TM clone if _ITM_beginTransaction says to
run instrumented code? If not, what is the point of the attribute?
