[multiple changes]
2010-10-12 Pascal Obry <obry@adacore.com>
* adaint.c (__gnat_number_of_cpus): Add implementation for Windows.
2010-10-12 Arnaud Charlet <charlet@adacore.com>
* make.adb (Globalize): New procedure.
(Compile): Set Do_Codepeer_Globalize_Step when -gnatC is used.
(Gnatmake): Call Globalize when needed.
(Process_Restrictions_Or_Restriction_Warnings): Ignore Restrictions
pragmas in CodePeer mode.
(Adjust_Global_Switches): Set No_Initialize_Scalars in CodePeer mode,
to generate simpler and consistent code.
2010-10-12 Bob Duff <duff@adacore.com>
* exp_util.adb (Remove_Side_Effects): Disable previous change,
can cause side effects to be duplicated.
