- remove all inline assembly versions - implement the atomic operations using either GCC intrinsics, the Windows interlocked API or a mutex-based fallback - drop gatomic-gcc.c since these are now defined in the header file. Adjust Makefile.am accordingly. - expand the set of operations: support 'get', 'set', 'compare and exchange', 'add', 'or', and 'xor' for both integers and pointers - deprecate g_atomic_int_exchange_and_add since g_atomic_int_add (as with all the new arithmetic operations) now returns the prior value - unify the use of macros: all functions are now wrapped in macros that perform the proper casts and checks - remove G_GNUC_MAY_ALIAS use; it was never required for the integer operations (since casting between pointers that only vary in signedness of the target is explicitly permitted) and we avoid the need for the pointer operations by using simple 'void *' instead of 'gpointer *' (which caused the 'type-punned pointer' warning) - provide function implementations of g_atomic_int_inc and g_atomic_int_dec_and_test: these were strictly macros before - improve the documentation to make it very clear exactly which types of pointers these operations may be used with - remove a few uses of the now-deprecated g_atomic_int_exchange_and_add - drop initialisation of gatomic from gthread (by using a GStaticMutex instead of a GMutex) - update glib.symbols and documentation sections files Closes #650823 and #650935 |

This package contains the reference documentation for GLib. For more information about Glib, see: http://www.gtk.org For information about contributing to the GLib/GTK+ reference documentation project, see: http://www.gtk.org/rdp/ The GLib reference documentation is freely redistributable, see the file COPYING for details. REQUIREMENTS ============ To build the documentation, you must have the gtk-doc package installed. To rebuild the template files, you must have the current version of the GLib header files installed. BUILD ===== First, run configure to generate the makefiles for this module. There is one option specific to this package --with-html-dir=DIR top of installed HTML documentation tree The Makefiles for this module define three targets: templates: Scan the headers and merge the results with the current template files sgml: Generate SGML files using the DocBook DTD from the template files html: Generate HTML from the SGML files. To build the documentation, do: make sgml make html You should only run the 'make templates' step if you need to regenerate the templates for a more recent version of the GLib sources. INSTALLATION ============ make install
