           Product: gcc

            Status: UNCONFIRMED
          Severity: normal
          Priority: P3

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
