2014-11-20 Pascal Obry <obry@adacore.com> * initialize.c (ProcListCS): New extern variable (critical section). (ProcListEvt): New extern variable (handle). (__gnat_initialize)[Win32]: Initialize the ProcListCS critical section object and the ProcListEvt event. * final.c (__gnat_finalize)[Win32]: Properly finalize the ProcListCS critical section and the ProcListEvt event. * adaint.c (ProcListEvt): New Win32 event handle. (EnterCS): New routine to enter the critical section when dealing with child processes chain list. (LeaveCS): As above to exit from the critical section. (SignalListChanged): Routine to signal that the chain process list has been updated. (add_handle): Use EnterCS/LeaveCS, also call SignalListChanged when the handle has been added. (__gnat_win32_remove_handle): Use EnterCS/LeaveCS, also call SignalListChanged if the handle has been found and removed. (remove_handle): Routine removed, implementation merged with the above. (win32_wait): Use EnterCS/LeaveCS for the critical section. Properly copy the PID list locally to ensure that even if the list is updated the local copy remains valid. Add into the hl (handle list) the ProcListEvt handle. This handle is used to signal that a change has been made into the process chain list. This is to ensure that a waiting call can be resumed to take into account new processes. We also make sure that if the handle was not found into the list we start over the wait call. Indeed another concurrent call to win32_wait() could already have handled this process. 2014-11-20 Ed Schonberg <schonberg@adacore.com> * sem_res.adb (Resolve_Actuals): The legality rule concerning the use of class-wide actuals for a non-controlling formal are not rechecked in an instance. 2014-11-20 Pascal Obry <obry@adacore.com> * g-dirope.ads: Minor typo fix. 2014-11-20 Hristian Kirtchev <kirtchev@adacore.com> * exp_attr.adb (Expand_N_Attribute_Reference, Expand_Update_Attribute): Preserve the tag of a prefix by offering a specific view of the class-wide version of the prefix.

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
