2017-01-27  Pekka Jaaskelainen  <pekka.jaaskelainen@parmance.com>

	* configure.ac: Moved the white list of enabling BRIG FE to
	libhsail-rt/configure.tgt.  
	* configure: Regenerated.
	* MAINTAINERS: Updated maintainers for BRIG FE and libhsail-rt.

gcc/
	* builtin-types.def: Use unsigned_char_type_node for BT_UINT8.  Use
	uint16_type_node for BT_UINT16.

gcc/brig/
	* config-lang.in: Removed stale target-libbrig reference.

libhsail-rt/
	* configure.tgt: Moved the white list of supported targets here
	from configure.ac.  Added i[3456789]86-*-linux* as a supported env
	for the BRIG FE.

-Run autoconf2.64 && automake-1.11  to regenerate the buildfiles.
-You might need to manually tweak the minor automake version number
-in configure.ac and aclocal.m4 (search for 1.11.6) in case your
-local 1.11 minor version doesn't match.

+This library implements the agent-side runtime functionality required
+to run HSA finalized programs produced by the BRIG frontend.
+
+The library contains both the code required to run kernels on the agent
+and also functions implementing more complex HSAIL instructions.
+
+rt/workitems.c contains the runtime entry function that manages multiple
+work-item execution using fibers or simple for-loops (in case of work groups
+without barriers).  Otherwise, the rest of the source files mostly contain
+functions that typically map directly to HSAIL instructions.
