*	Fix regression from r151466: an we can't replace uses of an instruction ↵	Eli Friedman	2012-03-13	1	-0/+19
\| \| \| \| \| \|	reachable from the entry block with uses of an instruction not reachable from the entry block. PR12231. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@152595 91177308-0d34-0410-b5e6-96231b3b80d8
*	Replace all instances of dg.exp file with lit.local.cfg, since all tests are ↵	Eli Bendersky	2012-02-16	2	-3/+1
\| \| \| \| \| \| \| \| \| \| \|	run with LIT now and now Dejagnu. dg.exp is no longer needed. Patch reviewed by Daniel Dunbar. It will be followed by additional cleanup patches. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@150664 91177308-0d34-0410-b5e6-96231b3b80d8
*	Upgrade syntax of tests using volatile instructions to use 'load volatile' ↵	Chris Lattner	2011-11-27	1	-5/+5
\| \| \| \| \| \|	instead of 'volatile load', which is archaic. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@145171 91177308-0d34-0410-b5e6-96231b3b80d8
*	Move "atomic" and "volatile" designations on instructions after the opcode	Eli Friedman	2011-08-12	1	-5/+5
\| \| \| \| \| \| \| \| \| \| \| \|	of the instruction. Note that this change affects the existing non-atomic load and store instructions; the parser now accepts both forms, and the change is noted in the release notes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@137527 91177308-0d34-0410-b5e6-96231b3b80d8

\| \| \| \| \| \| \| \|	elimination as well. This deletes 60 stores in 176.gcc that largely come from bitfield code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@122736 91177308-0d34-0410-b5e6-96231b3b80d8
*	now that loads are in their own table, we can implement	Chris Lattner	2011-01-03	1	-0/+9
\| \| \| \| \| \| \| \|	store->load forwarding. This allows EarlyCSE to zap 600 more loads from 176.gcc. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@122732 91177308-0d34-0410-b5e6-96231b3b80d8

\| \| \| \|	git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@122730 91177308-0d34-0410-b5e6-96231b3b80d8
*	Teach EarlyCSE to do trivial CSE of loads and read-only calls.	Chris Lattner	2011-01-03	1	-0/+45
\| \| \| \| \| \| \| \| \|	On 176.gcc, this catches 13090 loads and calls, and increases the number of simple instructions CSE'd from 29658 to 36208. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@122727 91177308-0d34-0410-b5e6-96231b3b80d8
*	add DEBUG and -stats output to earlycse.	Chris Lattner	2011-01-02	1	-2/+13
\| \| \| \| \| \| \| \|	Teach it to CSE the rest of the non-side-effecting instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@122716 91177308-0d34-0410-b5e6-96231b3b80d8
*	Enhance earlycse to do CSE of casts, instsimplify and die.	Chris Lattner	2011-01-02	2	-0/+24
	Add a testcase. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@122715 91177308-0d34-0410-b5e6-96231b3b80d8
