Hi,
I am using DejaGNU on GCC's Testsuite and a problem appeared to me, some tests
fail when they shouldn't be.
For example: The test gcc.dg/pr27528.c has the line " /* { dg-options "" } */ "
which means that this test should be compiled without any options, right? But
DejaGNU seems to pass some basic options anyway (for ex. -O1, -O2, etc...) and
this causes the test to fail because it is meant to be tested without
optimizations.
I saw this problem with a lot more testcases causing them to have two
optimization level in the same command line "gcc ... -O1 -O2 -o ...". This
problem seems to happen when the testcase has some specific options in the line
dg_options, for ex. " /* { dg-options "-O2" } */ ".
Did anyone ever try to run the GCC testsuite with DejaGNU and notice this kind
of things?
I'm using DejaGNU 1.5
Thanks,
Didier
