Implement a check whether pthread_t objects can be used by GCC atomic builtin functions. This check is implemented in plug.in and defines the macro HAVE_ATOMIC_PTHREAD_T. This macro is checked in univ.i and the relevant part of the code enabled (the one that uses GCC atomics against pthread_t objects). In addition to this, the same program that is compiled as part of the plug.in check is added in ut/ut0auxconf.c. In the InnoDB Plugin source archives that are shipped to the users, a generated Makefile.in is added. That Makefile.in will be modified to compile ut/ut0auxconf.c and define the macro HAVE_ATOMIC_PTHREAD_T if the compilation succeeds. I.e. Makefile.in will emulate the work that is done by plug.in. This is done in order to make the check happen and HAVE_ATOMIC_PTHREAD_T eventually defined without regenerating MySQL's ./configure from ./storage/innobase/plug.in. The point is not to ask users to install the autotools and regenerate ./configure. rb://95 Approved by: Marko |
