Hello,Here's an updated version of my patch, adding initial DTrace support to the Mono runtime.
A new hand-crafted header file has been added, which is to be included in place of the generated header file. It defines MONO_PROBE_* macros as requested by Zoltan. The generated header file is then only needed iff DTrace is enabled.
Ugly build steps for Solaris were moved to a shell script. It extracts object files from their library to a temporary directory, patches them and puts them back in. This helps keep Makefiles clean and provides a one-stop resource to fix things, should they break. Tested on OpenSolaris 2008.05 i86. (Warning: I am not experienced in writing shell scripts.)
It appears the problem with the gc-end probe on Solaris was due to some kind of compiler optimization or the like. Adding a trailing sleep(0) call made it work; I have limited this workaround to when the gc-end probe is enabled on Solaris, to minimize the impact. Better ideas welcome. If we do stick with it and it turns out this is needed in more void functions, we could consider turning this into a MONO_PROBE_* macro to keep source files clean.
