Subject: Fix assembler name collision
X-Git-Tag: releases/gcc-10.3.0~537
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=95e76abccf109803db9e0a00bfae97921ac94ef4;p=thirdparty%2Fgcc.git

Fix assembler name collision

Gigi uses a dummy global variable to register global types for debug
info purposes and its name can now collide with user variables.

gcc/ada/ChangeLog:
	* gcc-interface/utils.c (gnat_write_global_declarations): Use the
	maximum index for the dummy object to avoid a name collision.
