[PATCH, testsuite] Stabilize test result output of dump-noaddr

2016-01-12 Thread Thomas Preud'homme 
Hi,

Everytime the static pass number of passes change, testsuite output for dump-
noaddr will change, leading to a series of noise lines like the following 
under dg-cmp-results:

This patch solve this problem by replacing the static pass number in the 
output by a star, allowing for a stable output while retaining easy copy/
pasting in shell.

ChangeLog entry is as follows:


*** gcc/testsuite/ChangeLog ***

2015-12-30  Thomas Preud'homme  

* gcc.c-torture/unsorted/dump-noaddr.x (dump_compare): Replace static
pass number in output by a star.

Is this ok for stage3?
