* Add test suite for declaration resolutionJames Bottomley2008-07-094-40/+59
| | | | | | | | | | This adds the test declaration.exp which checks that specific named declarations inside the kernel both fail and succeed. We get the failure by only using a single compile unit which is currently known to have the structure stubbed. We get exactly the same declaration to succeed by adding a CU that is known to have the declaration. Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>

In that context its as global as a lot of the other static data in that structure (like this_session) which would also have to be fixed to do a multiple target system. Regardless, it can become per instance: it will only screw up if dwflpp moves to being short lived. James
* Add hack to support git 1.6 in git_version.shTheodore Ts'o2008-07-091-0/+23
| | | | | | | | | | | | | | | | | | | This is needed now for people who are running the "master" branch of git, which is currently in development for git version 1.6.0. This is a kludge to support hyphenated git commands (i.e., git-diff-files), but this form is explicitly deprecated, and doesn't work in git 1.6 unless you put git's execdir (obtained via git --exec-path) in your PATH environment variable. Even then, these programs may no longer exist future versions of git. It would be better to change the script to use "git diff-files", et. al., but I assume upstream had some vaguely justifiable reason for not writing the script that way. I'll let them decide when they are willing to fix the script the right way, even if it means breaking compatibility for some ancient version of git. n.b., git 1.5.0 was released February 2007, and git 1.4.0 was released June, 2006.
