2009-03-02Generalize BuildVectorSDNode::isConstantSplat to use APInts and handleBob Wilson
arbitrary vector sizes. Add an optional MinSplatBits parameter to specify a minimum for the splat element size. Update the PPC target to use the revised interface. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@65899 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-24Overhaul my earlier submission due to feedback. It's a large patch, but most ofBill Wendling
them are generic changes. - Use the "fast" flag that's already being passed into the asm printers instead of shoving it into the DwarfWriter. - Instead of calling "MI->getParent()->getParent()" for every MI, set the machine function when calling "runOnMachineFunction" in the asm printers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@65379 91177308-0d34-0410-b5e6-96231b3b80d8

Generate better code for v16i8 shuffles on SSE2 (avoids stack) Generate pshufb for v8i16 and v16i8 shuffles on SSSE3 where it is fewer uops.

2009-02-21Drop bunch of half-working stuff in the ext_weak linkage support.Anton Korobeynikov
Now we're using one gross, but quite robust hack :) (previous ones did not work, for example, when ext_weak symbol was used deep inside constant expression in the initializer). The proper fix of this problem will require some quite huge asmprinter changes and that's why was postponed. This fixes PR3629 by the way :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@65230 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-18Add support to the JIT for true non-lazy operation. When a call to a functionNate Begeman
that has not been JIT'd yet, the callee is put on a list of pending functions to JIT. The call is directed through a stub, which is updated with the address of the function after it has been JIT'd. A new interface for allocating and updating empty stubs is provided. Add support for removing the ModuleProvider the JIT was created with, which would otherwise invalidate the JIT's PassManager, which is initialized with the ModuleProvider's Module. Add support under a new ExecutionEngine flag for emitting the infomration necessary to update Function and GlobalVariable stubs after JITing them, by recording the address of the stub and the name of the GlobalValue. This allows code to be copied from one address space to another, where libraries may live at different virtual addresses, and have the stubs updated with their new correct target addresses. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@64906 91177308-0d34-0410-b5e6-96231b3b80d8
