* prj-env.adb: Remove local debug traces.
2011-08-04 Yannick Moy <moy@adacore.com>
* checks.adb (Apply_Float_Conversion_Check): correct a typo where Lo_OK
was used instead of Hi_OK, which could cause a read of an uninitialized
value later on. Detected while working on the new warning.
* exp_ch9.adb (Expand_N_Entry_Declaration): remove useless assignment
to local variable.
* sem_ch5.adb (Analyze_Assignment): set the last assignment component
in more cases, in order to detect more unreferenced values.
* sem_util.adb, sem_util.ads (Get_Enclosing_Object): return enclosing
object for expression, if any.
2011-08-04 Eric Botcazou <ebotcazou@adacore.com>
* exp_intr.adb (Expand_Binary_Operator_Call): Look at the RM size of
the operand types instead of the Esize.
2011-08-04 Steve Baird <baird@adacore.com>
* switch-b.adb (Scan_Binder_Switches): Add -P binder switch, used to
enable CodePeer_Mode.
* bindusg.adb (Display): Add help message describing -P binder switch.
* gnat_ugn.texi: Document -P binder switch.
* bindgen.adb (Gen_Main_Ada): If CodePeer_Mode is set, then call the
user-defined main program directly.
(Gen_Output_File_Ada): If CodePeer_Mode is set, generate a with of the
user-defined main program in the context clause of the package body.
