2010-10-19	Get rid of static constructors for pass registration. Instead, every pass ↵	Owen Anderson	1	-1/+3
	exposes an initializeMyPassFunction(), which must be called in the pass's constructor. This function uses static dependency declarations to recursively initialize the pass's dependencies. Clients that only create passes through the createFooPass() APIs will require no changes. Clients that want to use the CommandLine options for passes will need to manually call the appropriate initialization functions in PassInitialization.h before parsing commandline arguments. I have tested this with all standard configurations of clang and llvm-gcc on Darwin. It is possible that there are problems with the static dependencies that will only be visible with non-standard options. If you encounter any crash in pass registration/creation, please send the testcase to me directly. llvm-svn: 116820
2010-10-07	Now with fewer extraneous semicolons!	Owen Anderson	1	-1/+1
	llvm-svn: 115996
2010-08-06	Reapply r110396, with fixes to appease the Linux buildbot gods.	Owen Anderson	1	-1/+1
	llvm-svn: 110460
2010-08-06	Revert r110396 to fix buildbots.	Owen Anderson	1	-1/+1
	llvm-svn: 110410
2010-08-05	Don't use PassInfo* as a type identifier for passes. Instead, use the ↵	Owen Anderson	1	-1/+1
	address of the static ID member as the sole unique type identifier. Clean up APIs related to this change. llvm-svn: 110396
2010-07-21	Fix batch of converting RegisterPass<> to INTIALIZE_PASS().	Owen Anderson	1	-2/+2
	llvm-svn: 109045
2010-07-16	Remove many calls to TII::isMoveInstr. Targets should be producing COPY anyway.	Jakob Stoklund Olesen	1	-10/+4
	TII::isMoveInstr is going tobe completely removed. llvm-svn: 108507
2010-07-03	Detect and handle COPY in many places.	Jakob Stoklund Olesen	1	-0/+5
	This code is transitional, it will soon be possible to eliminate isExtractSubreg, isInsertSubreg, and isMoveInstr in most places. llvm-svn: 107547
2010-02-13	Besides removing phi cycles that reduce to a single value, also remove dead	Bob Wilson	1	-20/+68
	phi cycles. Adjust a few tests to keep dead instructions from being optimized away. This (together with my previous change for phi cycles) fixes Apple radar 7627077. llvm-svn: 96057
2010-02-12	Add a new pass on machine instructions to optimize away PHI cycles that	Bob Wilson	1	-0/+141
	reduce down to a single value. InstCombine already does this transformation but DAG legalization may introduce new opportunities. This has turned out to be important for ARM where 64-bit values are split up during type legalization: InstCombine is not able to remove the PHI cycles on the 64-bit values but the separate 32-bit values can be optimized. I measured the compile time impact of this (running llc on 176.gcc) and it was not significant. llvm-svn: 95951
