2014-08-01	Change inchash to name space.	Andi Kleen	1	-5/+13
	Change class inchash to move into a inchash namespace as requested. The class is now inchash::hash Rename iterative_hstate_expr to inchash::add_expr ... and convert existing users. It wasn't possible to use hash::, because that lead to name space conflicts with cp and objc. So class inchash is now inchash::hash and iterative_hstate_expr is now inchash::add_expr. gcc/: 2014-07-31 Andi Kleen <ak@linux.intel.com> * inchash.h (inchash): Change inchash class to namespace.

2014-07-25	Add an abstract incremental hash data type	Andi Kleen	1	-0/+129
	Some files in gcc, like lto or tree, do large scale incremential hashing. The current jhash implementation of this could be likely improved by using an incremential hash that does not do a full rehashing for every new value added. This patch adds a new "inchash" class that abstracts the internal state of the hash. This makes it easier to plug in new hashes and also cleans up the code a bit. Right now it is just implemented in the same way as the old iterative hash in tree.c. The previous iterative hash code from tree.c moved into a new separate file. Also I fixed up all users to include the new header. It should not really significantly change any hashing by itself, it's mostly a cleanup at this point. v2: Remove begin. Add commutative interface. Add merge hash interface. Add add_flag. gcc/: 2014-07-25 Andi Kleen <ak@linux.intel.com> * Makefile.in (OBJS): Add inchash.o.
