a compile time perf optimization to avoid a load. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@90507 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-04Also attempt trivial coalescing for live intervals that end in a copy.Jakob Stoklund Olesen
The coalescer is supposed to clean these up, but when setting up parameters for a function call, there may be copies to physregs. If the defining instruction has been LICM'ed far away, the coalescer won't touch it. The register allocation hint does not always work - when the register allocator is backtracking, it clears the hints. This patch takes care of a few more cases that r90163 missed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@90502 91177308-0d34-0410-b5e6-96231b3b80d8

2009-12-03Add ParseInlineMetadata() which can parses metadata that refers to an ↵Victor Hernandez
instruction. Extend ParseParameterList() to use this new function so that calls to llvm.dbg.declare can pass inline metadata git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@90497 91177308-0d34-0410-b5e6-96231b3b80d8

2009-12-03Fix ExpandShiftWithUnknownAmountBit, which was completely bogus.Duncan Sands
Pointed out by Javier Martinez (who also provided a patch). Since this logic is not used on (for example) x86, I guess nobody noticed. Tested by generating SHL, SRL, SRA on various choices of i64 for all possible shift amounts, and comparing with gcc. Since I did this on x86-32, I had to force the use of ExpandShiftWithUnknownAmountBit. What I'm saying here is that I don't have a testcase I can add to the repository. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@90482 91177308-0d34-0410-b5e6-96231b3b80d8

2009-12-03This initial code is meant to convert TargetData to use an AbstractTypesUser soBill Wendling
that it doesn't have dangling pointers when abstract types are resolved. This modifies it somewhat to address comments: making the "StructLayoutMap" an anonymous structure, calling "removeAbstractTypeUser" when appropriate, and adding asserts where helpful. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@90362 91177308-0d34-0410-b5e6-96231b3b80d8
