UNIX for Advanced & Expert Users

Hi,

I am unable to run a selective set of tests in gcc-4.5.1 test suite.
I tried two runtest commands given below (output is also given below).
Can you please guide me how to run specific set of tests for example :
I would like to run only tests gcc.target/i386/avx-vaddpd-1.c and gcc.target/i386/avx-vaddpd-256-1.c ?


Command-1:This command runs 10 tests but does not run one the i mentioned gcc.target/i386/avx-vaddpd-1.c

Code:

$ cd gcc/testsuite 
$ runtest -tool_exec gcc --src-dir=. --tool gcc  i386.exp=gcc.target/i386/avx-vaddpd-1.c

Output:
WARNING: Couldn't find the global config file.
Test Run By root on Tue Jan 25 21:05:23 2011
Native configuration is x86_64-unknown-linux-gnu
