2007-03-16Add more comments and update to new asm syntax.Nick Lewycky
Add new micro-optimizations. Add icmp predicate snuggling. Given %x ULT 4, "icmp ugt %x, 2" becomes "icmp eq %x, 3". This doesn't apply in any non-trivial cases yet due to missing support for NE values in ValueRanges. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@35119 91177308-0d34-0410-b5e6-96231b3b80d8

2007-03-14The sign information was not propagating into the rename map so only theReid Spencer
last entry stored in the map could be retrieved for a given integer type. Propagating the sign information required an invasive change to ensure that all ValueRef (ValID) instances get the right sign information as well. Also, put in some assertions to ensure the RenameMap always gives us out the type that is expected. This fixes PR1256 and test/Assembler/2007-03-14-UgpradeLocalSignless.ll git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@35112 91177308-0d34-0410-b5e6-96231b3b80d8

2007-03-14Test case for PR1256.Reid Spencer

2007-03-14Estimate a cost using the possible number of scratch registers required and useEvan Cheng
it as a late BURR scheduling tie-breaker. Intuitively, it's good to push down instructions whose results are liveout so their long live ranges won't conflict with other values which are needed inside the BB. Further prioritize liveout instructions by the number of operands which are calculated within the BB. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@35109 91177308-0d34-0410-b5e6-96231b3b80d8

2007-03-13Try schedule def + use closer whne Sethi-Ullman numbers are the same.Evan Cheng
e.g. t1 = op t2, c1 t3 = op t4, c2 and the following instructions are both ready. t2 = op c3 t4 = op c4 Then schedule t2 = op first. i.e. t4 = op c4 t2 = op c3 t1 = op t2, c1 t3 = op t4, c2 This creates more short live intervals which work better with the register allocator. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@35089 91177308-0d34-0410-b5e6-96231b3b80d8
