Bug ID: 59130
Summary: Inline(d) or static functions not registered in
transactional clone table
Product: gcc

Status: UNCONFIRMED
Severity: normal

Test case to reproduce the bug
When a function pointer is used in a transactional section to call a function
the STM library (such as libitm) has to lookup the corresponding transactional
function 'clone' of that function. The compiler therefore generates mapping
tables which associate function pointers of non-transactional functions with
their corresponding transactional function clones.
With the STAMP benchmark suite I have experienced that the compiler does not
generate entries in the lookup table for functions which are declared as static
or inline.
I have written a small test case to reproduce the bug (see attachment).
Compile with:
/usr/bin/g++-4.7 -fgnu-tm -Wall -g -O3 -o gnutm-test main.cpp -lpthread -litm
