* prj.ads (Language_Ptr): Make a general access type.

[gcc.git] / gcc / ada / ChangeLog

2009-04-24  Arnaud Charlet  <charlet@adacore.com>

	* s-tassta.adb (Create_Task): Fix violation of locking rule.

2009-04-24  Emmanuel Briot  <briot@adacore.com>

	* prj.adb, prj.ads, prj-nmsc.adb, prj-env.adb (Language_Index): renamed
	to Language_Ptr to better reflect its new implementation.
	(Project_Data.First_Languages_Processing): renamed to Languages now
	that the field with that name is no longer used
	(Project_Data.Languages): removed, no longer used, and duplicates
	information already available through First_Language_Processing.

	a table. This makes the list somewhat more obvious, but more importantly
	removes the need to pass a pointer to the project_tree_data in a few
	places, and makes accessing the attributes of a languages more
	efficient.

	Check_Infinite_Loop_Warning.

	* sem_warn.adb (Check_Infinite_Loop_Warning): If the local variable
	tested in the while loop is a renaming, do not warn. Otherwise, we get
	false alarms, because it's usually renaming something that we can't

	of a controlled function call in the context of a record aggregate.
