* Fix on_each_cpu() call for kernels >2.6.26.Josh Stone2008-07-245-1/+15
| | | | | | | | This is a generalization of the patch from James Bottomley: http://sources.redhat.com/ml/systemtap/2008-q3/msg00220.html The on_each_cpu() change was merged *after* the 2.6.26 release, so I'm using an autoconf test instead of James' version check.

* fix semantic error: no entrypc found using probe .statement(*@file:line) ↵James Bottomley2008-07-231-2/+2
| | | | | | | | | | | | | | | | | constructs At the moment, you can't specify probe module("scsi_mod").statement(*@drivers/scsi/scsi_lib.c:1443) because the compiler will fail with the above semantic error on the function scsi_end_bidi_request. It seems looking through the dwarf that this function is fully inlined and thus has no entrypc to catalogue. The solution therefore seems to simply return DWARF_CB_OK when we find such functions and continue cataloguing all the ones that do actually have non-inline versions.

* fix missing functions in cachesJames Bottomley2008-07-151-40/+44
| | | | | | | | | | | | | | | | | | | | Both the inline and non inline filtered function caches can lose functions. This happens because both of these caches are indexed by the entrypc. However, the vagaries of optimisation can actually cause us to end up with two functions with apparently the same entrypc (mainly because for inline functions, the entrypc has to be deduced from the range of addresses, which is nastily heuristic). A nice example of this is bsg_io_schedule. In my build of 2.6.26 it's a static function transformed to an inline by the compiler. The range deduction of its entrypc ends up being identical to that of bsg_release, so when I try to place a probe inside it, none of the function references actually refers to it. Since nothing ever actually makes use of this index, the fix is simple: don't use a map indexed on the entrypc, use a simple vector.

We get the failure by only using a single compile unit which is currently known to have the structure stubbed.

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.
