commit 6e89caf118d4091356ff79a7a3e9d5439c231cd1
Author: Joseph Myers <joseph@codesourcery.com>
Date:   Fri Feb 14 13:42:44 2014 +0000

    Split up rules for tests that compare output with baselines.
    
    This patch splits makefile rules that generate a file then run cmp to
    check the contents of that file into separate rules to generate and
    compare the file.  This simplifies making those tests generate PASS /
    FAIL results, by removing the need to insert && between commands in
    the test so that a $(evaluate-test) call is reached.  It also avoids
    the oddity of the .out file being an intermediate file rather than the
    final result generated, as noted for some of these tests in
    <https://sourceware.org/ml/libc-alpha/2012-10/msg00894.html>.
    
    In many cases, the rule to run the program was no longer needed
    because the default rules for running test programs on the host to
    generate a .out file sufficed.  (I'm not asserting the commands run
    after this patch are *exactly* the same as before, simply that the
    rules did nothing special that appeared deliberate or relevant to
    anything about what the tests were testing.  In cases where the rules
    redirected stderr as well as stdout, I left the existing rule's
    redirection in place to avoid changing what gets compared with the
    expected results.)
    
    It's clear there is a lot in common between the various -cmp.out rules
    and it might be possible in future to refactor them into more generic
    support for the case of comparing test output against a baseline.
    (Some baselines are *.exp, some *.expect, some directly embedded in
    the makefiles, and nptl/tst-cleanupx0.expect appears unused.)
    
    Tested x86_64.
