* Change tblgen to emit FOOISD opcode names as twoChris Lattner2010-03-252-13/+20
| | | | | | | | | | | | | | bytes instead of one byte. This is important because we're running up to too many opcodes to fit in a byte and it is aggrevated by FIRST_TARGET_MEMORY_OPCODE making the numbering sparse. This just bites the bullet and bloats out the table. In practice, this increases the size of the x86 isel table from 74.5K to 76K. I think we'll cope :) This fixes rdar://7791648 llvm-svn: 99494

* Fix evil TableGen bug in template parameters with defaults.Jakob Stoklund Olesen2010-03-253-11/+61
| | | | | | | | | | If a TableGen class has an initializer expression containing an X.Y subexpression, AND X depends on template parameters, AND those template parameters have defaults, AND some parameters with defaults are beyond position 1, THEN parts of the initializer expression are evaluated prematurely with the default values when the first explicit template parameter is substituted, before the remaining explicit template parameters have been substituted. llvm-svn: 99492

* eliminate a bunch more parallels now that schedulingChris Lattner2010-03-251-205/+150

* Make the NDEBUG assertion stronger and more clear what is Chris Lattner2010-03-257-11/+25
| | | | | | | | | | | | | | | | | | | | | happening. Enhance scheduling to set the DEAD flag on implicit defs more aggressively. Before, we'd set an implicit def operand to dead if it were present in the SDNode corresponding to the machineinstr but had no use. Now we do it in this case AND if the implicit def does not exist in the SDNode at all. This exposes a couple of problems: one is the FIXME, which causes a live intervals crash on CodeGen/X86/sibcall.ll. The second is that it makes machinecse and licm more aggressive (which is a good thing) but also exposes a case where licm hoists a set0 and then it doesn't get resunk. Talking to codegen folks about both these issues, but I need this patch in in the meantime. llvm-svn: 99485

* Change how dbg_value sdnodes are converted into machine instructions. Their ↵Evan Cheng2010-03-258-145/+225
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | placement should be determined by the relative order of incoming llvm instructions. The scheduler will now use the SDNode ordering information to determine where to insert them. A dbg_value instruction is inserted after the instruction with the last highest source order and before the instruction with the next highest source order. It will optimize the placement by inserting right after the instruction that produces the value if they have consecutive order numbers. Here is a theoretical example that illustrates why the placement is important. tmp1 = store tmp1 -> x ... tmp2 = add ... ... call ... store tmp2 -> x Now mem2reg comes along: tmp1 = dbg_value (tmp1 -> x) ... tmp2 = add ... ... call ... dbg_value (tmp2 -> x) When the debugger examine the value of x after the add instruction but before the call, it should have the value of tmp1. Furthermore, for dbg_value's that reference constants, they should not be emitted at the beginning of the block (since they do not have "producers"). This patch also cleans up how SDISel manages DbgValue nodes. It allow a SDNode to be referenced by multiple SDDbgValue nodes. When a SDNode is deleted, it uses the information to find the SDDbgValues and invalidate them. They are not deleted until the corresponding SelectionDAG is destroyed. llvm-svn: 99469

* Disable folding loads into tail call in 32-bit PIC mode. It can introduce ↵Evan Cheng2010-03-251-1/+5
| | | | | | | | | | | | | | | | | illegal code like this: addl $12, %esp popl %esi popl %edi popl %ebx popl %ebp jmpl *__Block_deallocator-L1$pb(%esi) # TAILCALL The problem is the global base register is assigned GR32 register class. TCRETURNmi needs the registers making up the address mode to have the GR32_TC register class. The *proper* fix is for X86DAGToDAGISel::getGlobalBaseReg() to return a copy from the global base register of the machine function rather than returning the register itself. But that has the potential of causing it to be coalesced to a more restrictive register class: GR32_TC. It can introduce additional copies and spills. For something as important the PIC base, it's not worth it especially since this is not an issue on 64-bit. llvm-svn: 99455
