2013-12-07	Fix DTrace build on Illumos	Ryan Zezeski
	DTrace was recently patched in Illumos to fail to create an object file if no probes are found. * https://www.illumos.org/issues/4248 * https://github.com/illumos/illumos-gate/commit/54a20ab41aadcb81c53e72fc65886e964e9add59 This patch fixes two issues: * Modify the configure script to pass an object file to `dtrace -G` that actually invokes a probe. * Remove creation of `dtrace_user.o` from the dyntrace Makefile. In a previous commit [1] Scott Fritchie relocated all the user probes into the VM proper due to difficulties with DTrace probes in shared libraries. The `dtrace_user.d` file is now empty and generates a header file with nothing in it. There is no longer any reason to generate `dtrace_user.o` because all the probes are in the VM. Thus all the steps for building `dtrace_user.o` have been removed. [1]: https://github.com/erlang/otp/commit/75552bd3bb4e7f3cf4dab81a5c81cf73b1d3fb99
2012-08-17	Relocate bodies of DTrace probes to the statically-linked VM.	Scott Lystig Fritchie
	Due to various operating systems (in both the DTrace and SystemTap worlds) not fully supporting DTrace probes (or SystemTap-compatibility mode probes) in shared libraries, we relocate those probes to the statically-linked virtual machine. This could be seen as pollution of the pristine VM by a (yet) experimental feature. However: 1. This code can be eliminated completely by the C preprocessor. 2. Leaving the probes in the dyntrace NIF shared library simply does not work correctly on too many platforms. Many thanks to Macneil Shonle at Basho for assisting when my RSI-injured fingers gave out. Tested on: * CentOS 5, SystemTap 1.3 * Solaris 10 (note) * Solaris 11 * OpenIndiana 151 * SmartOS 20120809T221258Z * FreeBSD 9.0-RELEASE (note) I had hoped to be able to test CentOS 6 + SystemTap 1.7, but the details of dealing with all dependencies for a 2.6.32-279.5.1.el6.x86_64 kernel are too time consuming right now. (note: Solaris 10 and FreeBSD 9.0-RELEASE can take a long time to compile)
