2005-03-17 Jose Ruiz <ruiz@adacore.com> * s-taprob.adb (Initialize_Protection): Initialize the protected object's owner to Null_Task. (Lock): If pragma Detect_Blocking is in effect and the caller of this procedure is already the protected object's owner then Program_Error is raised. In addition the protected object's owner is updated. (Lock_Read_Only): If pragma Detect_Blocking is in effect and the caller of this procedure is already the protected object's owner then Program_Error is raised. In addition the protected object's owner is updated. (Unlock): Remove the ownership of the protected object. * s-taprob.ads (Protection): Add the field Owner, used to store the protected object's owner. This component is needed for detecting one type of potentially blocking operations (external calls on a protected subprogram with the same target object as that of the protected action). Document the rest of the components. * s-tposen.adb, s-tpoben.adb (Initialize_Protection_Entries): Initialize the protected object's owner to Null_Task. (Lock_Read_Only_Entries): If pragma Detect_Blocking is in effect and the caller of this procedure is already the protected object's owner then Program_Error is raised. Do not raise Program_Error when this procedure is called from a protected action. (Unlock_Entries): Remove the ownership of the protected object. (Lock_Entries): If pragma Detect_Blocking is in effect and the caller of this procedure is already the protected object's owner then Program_Error is raised. Do not raise Program_Error when this procedure is called from a protected action. * s-tposen.ads, s-tpoben.ads (Protection_Entries): Add the field Owner, used to store the protected object's owner. * s-tpobop.adb (Protected_Entry_Call): If pragma Detect_Blocking is in effect and this procedure (a potentially blocking operation) is called from whithin a protected action, Program_Error is raised. (Timed_Protected_Entry_Call): If pragma Detect_Blocking is in effect and this procedure (a potentially blocking operation) is called from whithin a protected action, Program_Error is raised.

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the file 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.html for how to report bugs usefully.
