* lib: Automated cleanup of cdefs and other formattingWarner Losh2023-11-271-1/+0

* Refine symtab sorting in libproc.Mark Johnston2017-11-211-1/+91
| | | | | | | | | | | | Add some rules to more closely match what illumos does when an address resolves to multiple symbols: - prefer non-local symbols - prefer symbols with fewer leading underscores and no leading '$' Add some regression tests to verify these rules.

* libproc: Match prefixes when looking up mapped object by name.Mark Johnston2016-12-061-22/+19
| | | | | | | | | | | | | | | | | When looking up an object by name, allow prefix matches if no direct match is found. This allows one to, for example, match libc entry probes with: # dtrace -n 'pid$target:libc.so::entry' -c ./foo instead of requiring "libc.so.7" or a glob. Also remove proc_obj2map() as it currently just duplicates the functionality of proc_name2map(). It's supposed to take a Solaris link-map ID as a paramter, but support for this isn't implemented and isn't required to support DTrace's pid provider. Notes: svn path=/head/; revision=309595
* Enable libproc symbol_lookup tests on arm64Ed Maste2015-08-311-9/+0

| | | | | | | | | | | | | Each issue has a PR open to track. This workaround allows us to run the tests to investigate the failures and avoid any new regressions.

* Hook up support for userland CTF support in DTrace. This required someMark Johnston2014-10-031-4/+6
| | | | | | | | | | | | | | | | | | | | | modifications to libproc to support fetching the CTF info for a given file. With this change, dtrace(1) is able to resolve type info for function and USDT probe arguments, and function return values. In particular, the args[n] syntax should now work for referencing arguments of userland probes, provided that the requisite CTF info is available. The uctf tests pass if the test programs are compiled with CTF info. The current infrastructure around the DTrace test suite doesn't support this yet.
