If the type is "mod 2**12", for example, it's illegal, but Esize is the 'Object_Size, which will be something like 16 or 32, so the error ('Size = 12) was not detected. * gnat_rm.texi: Improve documentation of shift and rotate intrinsics. 2012-01-10 Pascal Obry <obry@adacore.com> * prj.adb (For_Every_Project_Imported): Fix implementation to make sure we return each project only once for aggragte libraries. It is fine to return a project twice for aggregate projects, this was the case as a Project_Id is different in each project tree. The new implementation use a table based on the project name to ensure proper detection of duplicate project in aggregate library. A new context is then created to continue retrurning duplicate project for aggregate libraries. 2012-01-09 Eric Botcazou <ebotcazou@adacore.com> * gcc-interface/trans.c (call_to_gnu): Create the temporary for the return value in the variable-sized return type case if the target is an array with fixed size.
