Questions about Gcc regression test.

[guo xuepeng <flameroc@xxxxxxxxx>]

Hi,

As we all known, there are many GCC test suites in GCC source code
directory. We can use command "make check" to run these suites to test
our just-built compiler. Does anybody know is it possible to test the
already-installed GCC (not the one we just built) using these test
suites via "make check"? Thanks for any suggestions.
