Subject: [Ada] Remove IN parameters from Alfa section in ALI
Date: Fri, 02 Sep 2011 09:22:00 -0000	[thread overview]
Message-ID: <20110902092223.GA11331@adacore.com> (raw)

[-- Attachment #1: Type: text/plain, Size: 340 bytes --]

References to IN parameters are not considered in Alfa section, as these will
be translated as constants in the intermediate language for formal
verification.

Tested on x86_64-pc-linux-gnu, committed on trunk

2011-09-02  Yannick Moy  <moy@adacore.com>

	* lib-xref-alfa.adb (Is_Alfa_Reference): Ignore IN parameters in Alfa
	references.
