* Expose InsertPreheaderForLoop from LoopSimplify to other passesHal Finkel2013-05-202-11/+38
| | | | | | | | | | | Other passes, PPC counter-loop formation for example, also need to add loop preheaders outside of the regular loop simplification pass. This makes InsertPreheaderForLoop a global function so that it can be used by other passes.

* Rename PPC MTCTRse to MTCTRloopHal Finkel2013-05-203-7/+7
| | | | | | | | | | As the pairing of this instruction form with the bdnz/bdz branches is now enforced by the verification pass, make it clear from the name that these are used only for counter-based loops. No functionality change intended. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@182296 91177308-0d34-0410-b5e6-96231b3b80d8
* Add a PPCCTRLoops verification passHal Finkel2013-05-203-0/+164
| | | | | | | | | | | | | | | | | | When asserts are enabled, this adds a verification pass for PPC counter-loop formation. Unfortunately, without sacrificing code quality, there is no better way of forming counter-based loops except at the (late) IR level. This means that we need to recognize, at the IR level, anything which might turn into a function call (or indirect branch). Because this is currently a finite set of things, and because SelectionDAG lowering is basic-block local, this can be done. Nevertheless, it is fragile, and failure results in a miscompile. This verification pass checks that all (reachable) counter-based branches are dominated by a loop mtctr instruction, and that no instructions in between clobber the counter register. If these conditions are not satisfied, then an ICE will be triggered. In short, this is to help us sleep better at night. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@182295 91177308-0d34-0410-b5e6-96231b3b80d8

* [SystemZ] Add long branch passRichard Sandiford2013-05-2017-37/+599
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before this change, the SystemZ backend would use BRCL for all branches and only consider shortening them to BRC when generating an object file. E.g. a branch on equal would use the JGE alias of BRCL in assembly output, but might be shortened to the JE alias of BRC in ELF output. This was a useful first step, but it had two problems: (1) The z assembler isn't traditionally supposed to perform branch shortening or branch relaxation. We followed this rule by not relaxing branches in assembler input, but that meant that generating assembly code and then assembling it would not produce the same result as going directly to object code; the former would give long branches everywhere, whereas the latter would use short branches where possible. (2) Other useful branches, like COMPARE AND BRANCH, do not have long forms. We would need to do something else before supporting them. (Although COMPARE AND BRANCH does not change the condition codes, the plan is to model COMPARE AND BRANCH as a CC-clobbering instruction during codegen, so that we can safely lower it to a separate compare and long branch where necessary. This is not a valid transformation for the assembler proper to make.) This patch therefore moves branch relaxation to a pre-emit pass. For now, calls are still shortened from BRASL to BRAS by the assembler, although this too is not really the traditional behaviour. The first test takes about 1.5s to run, and there are likely to be more tests in this vein once further branch types are added. The feeling on IRC was that 1.5s is a bit much for a single test, so I've restricted it to SystemZ hosts for now. The patch exposes (and fixes) some typos in the main CodeGen/SystemZ tests. A later patch will remove the {{g}}s from that directory. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@182274 91177308-0d34-0410-b5e6-96231b3b80d8

* [NVPTX] Add GenericToNVVM IR converter to better handle idiomatic LLVM IR inputsJustin Holewinski2013-05-208-80/+550
| | | | | | | | | | | | | | | This converter currently only handles global variables in address space 0. For these variables, they are promoted to address space 1 (global memory), and all uses are updated to point to the result of a cvta.global instruction on the new variable. The motivation for this is address space 0 global variables are illegal since we cannot declare variables in the generic address space. Instead, we place the variables in address space 1 and explicitly convert the pointer to address space 0. This is primarily intended to help new users who expect to be able to place global variables in the default address space. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@182254 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Introduction: In case when stack alignment is 8 and GPRs parameter part size is not N*8: we add padding to GPRs part, so part's last byte must be recovered at address K*8-1. We need to do it, since remained (stack) part of parameter starts from address K*8, and we need to "attach" "GPRs head" without gaps to it: Stack: |---- 8 bytes block ----| |---- 8 bytes block ----| |---- 8 bytes... [ [padding] [GPRs head] ] [ ------ Tail passed via stack ------ ... FIX: Note, once we added padding we need to correct *all* Arg offsets that are going after padded one. That's why we need this fix: Arg offsets were never corrected before this patch. See new test-cases included in patch. We also don't need to insert padding for byval parameters that are stored in GPRs only. We need pad only last byval parameter and only in case it outsides GPRs and stack alignment = 8. Though, stack area, allocated for recovered byval params, must satisfy "Size mod 8 = 0" restriction. This patch reduces stack usage for some cases: We can reduce ArgRegsSaveArea since inner N*4 bytes sized byval params my be "packed" with alignment 4 in some cases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@182237 91177308-0d34-0410-b5e6-96231b3b80d8

* Remove declaration of __clear_cache for __APPLE__. <rdar://problem/13924072>Bob Wilson2013-05-191-0/+3
| | | | | | | | | | | | | | | This fixes a bootstrapping problem with builds for Apple ARM targets. Clang had the wrong prototype for __clear_cache with ARM targets. Rafael fixed that in clang svn r181784 and r181810, but without those changes, we can't build this code for ARM because clang reports an error about the declaration in Memory.inc not matching the builtin declaration. Some of our buildbots need to use an older compiler that doesn't have the clang fix. Since __clear_cache is never used here when __APPLE__ is defined, I'm just conditionalizing the declaration to match that. I also moved the declaration of sys_icache_invalidate inside the conditional for __APPLE__ while I was at it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@182223 91177308-0d34-0410-b5e6-96231b3b80d8
