2012-05-17	Remove -join-physregs from the test suite.	Jakob Stoklund Olesen
	This option has been disabled for a while, and it is going away so I can clean up the coalescer code. The tests that required physreg joining to be enabled were almost all of the form "tiny function with interference between arguments and return value". Such functions are usually inlined in the real world. The problem exposed by phys_subreg_coalesce-3.ll is real, but fairly rare. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157027 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-30	Remove the pmulld intrinsic and autoupdate it as a vector multiply.	Eric Christopher
	Rewrite the pmulld patterns, and make sure that they fold in loads of arguments into the instruction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99910 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-08	Eliminate more uses of llvm-as and llvm-dis.	Dan Gohman

2009-02-11	Don't use special heuristics for nodes with no data predecessors	Dan Gohman
	unless they actually have data successors, and likewise for nodes with no data successors unless they actually have data precessors. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@64327 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-25	Teach 2addr pass to be do more commuting. If both uses of a two-address ↵	Evan Cheng
	instruction are killed, but the first operand has a use before and after the def, commute if the second operand does not suffer from the same issue. %reg1028<def> = EXTRACT_SUBREG %reg1027<kill>, 1 %reg1029<def> = MOV8rr %reg1028 %reg1029<def> = SHR8ri %reg1029, 7, %EFLAGS<imp-def,dead> insert => %reg1030<def> = MOV8rr %reg1028 %reg1030<def> = ADD8rr %reg1028<kill>, %reg1029<kill>, %EFLAGS<imp-def,dead> In this case, it might not be possible to coalesce the second MOV8rr instruction if the first one is coalesced. So it would be profitable to commute it: %reg1028<def> = EXTRACT_SUBREG %reg1027<kill>, 1 %reg1029<def> = MOV8rr %reg1028 %reg1029<def> = SHR8ri %reg1029, 7, %EFLAGS<imp-def,dead> insert => %reg1030<def> = MOV8rr %reg1029 %reg1030<def> = ADD8rr %reg1029<kill>, %reg1028<kill>, %EFLAGS<imp-def,dead> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@62954 91177308-0d34-0410-b5e6-96231b3b80d8
2008-12-18	Fix test to account for generating some vector code for mul v2i64 instead	Mon P Wang

2008-05-27	Make this test independent of the target-triple; the stack alignment	Dan Gohman
	is specifically what this test depends on. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@51599 91177308-0d34-0410-b5e6-96231b3b80d8
2008-05-26	The Linux ABI emits an extra "movl %esp, %ebp" in function prologue and	Nick Lewycky
	sometimes a "mov %ebp, %esp" in the epilogue. Force these tests that rely on counting 'mov' to use i686-apple-darwin8.8.0 where they were written. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@51568 91177308-0d34-0410-b5e6-96231b3b80d8
