* opt: Initialize asm printersTobias Grosser2014-06-13
| | | | | | | | | | | | | | Without initializing the assembly printers a shared library build of opt is linked with these libraries whereas for a static build these libraries are dead code eliminated. This is unfortunate for plugins in case they want to use them, as they neither can rely on opt to provide this functionality nor can they link the printers in themselves as this breaks with a shared object build of opt. This patch calls InitializeAllAsmPrinters() from opt, which increases the static binary size from 50MB -> 52MB on my system (all backends compiled) and causes no measurable increase in the time needed to run 'make check'. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@210914 91177308-0d34-0410-b5e6-96231b3b80d8

* Atomics: promote ARM's IR-based atomics pass to CodeGen.Tim Northover2014-04-17
| | | | | | | | | | | | Still only 32-bit ARM using it at this stage, but the promotion allows direct testing via opt and is a reasonably self-contained patch on the way to switching ARM64. At this point, other targets should be able to make use of it without too much difficulty if they want. (See ARM64 commit coming soon for an example). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@206485 91177308-0d34-0410-b5e6-96231b3b80d8
* verify-di: Implement DebugInfoVerifierDuncan P. N. Exon Smith2014-04-15
| | | | | | | | | | | | | | | | | | | | | Implement DebugInfoVerifier, which steals verification relying on DebugInfoFinder from Verifier. - Adds LegacyDebugInfoVerifierPassPass, a ModulePass which wraps DebugInfoVerifier. Uses -verify-di command-line flag. - Change verifyModule() to invoke DebugInfoVerifier as well as Verifier. - Add a call to createDebugInfoVerifierPass() wherever there was a call to createVerifierPass(). This implementation as a module pass should sidestep efficiency issues, allowing us to turn debug info verification back on. <rdar://problem/15500563> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@206300 91177308-0d34-0410-b5e6-96231b3b80d8

* Move duplicated code into a helper function (exposed through overload).Eli Bendersky2014-03-12
| | | | | | | | | | | | | | | | | | | There's a bit of duplicated "magic" code in opt.cpp and Clang's CodeGen that computes the inliner threshold from opt level and size opt level. This patch moves the code to a function that lives alongside the inliner itself, providing a convenient overload to the inliner creation. A separate patch can be committed to Clang to use this once it's committed to LLVM. Standalone tools that use the inlining pass can also avoid duplicating this code and fearing it will go out of sync. Note: this patch also restructures the conditinal logic of the computation to be cleaner. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@203669 91177308-0d34-0410-b5e6-96231b3b80d8
* Replace OwningPtr<T> with std::unique_ptr<T>.Ahmed Charles2014-03-06
| | | | | | | | | | This compiles with no changes to clang/lld/lldb with MSVC and includes overloads to various functions which are used by those projects and llvm which have OwningPtr's as parameters. This should allow out of tree projects some time to move. There are also no changes to libs/Target, which should help out of tree targets have time to move, if necessary. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@203083 91177308-0d34-0410-b5e6-96231b3b80d8

* Use DataLayout from the module when easily available.Rafael Espindola2014-02-25
| | | | | | | | | | | | | | | | | Eventually DataLayoutPass should go away, but for now that is the only easy way to get a DataLayout in some APIs. This patch only changes the ones that have easy access to a Module. One interesting issue with sometimes using DataLayoutPass and sometimes fetching it from the Module is that we have to make sure they are equivalent. We can get most of the way there by always constructing the pass with a Module. In fact, the pass could be changed to point to an external DataLayout instead of owning one to make this stricter. Unfortunately, the C api passes a DataLayout, so it has to be up to the caller to make sure the pass and the module are in sync. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@202204 91177308-0d34-0410-b5e6-96231b3b80d8
* Store a DataLayout in Module.Rafael Espindola2014-02-25
| | | | | | | | | | | | | | Now that DataLayout is not a pass, store one in Module. Since the C API expects to be able to get a char* to the datalayout description, we have to keep a std::string somewhere. This patch keeps it in Module and also uses it to represent modules without a DataLayout. Once DataLayout is mandatory, we should probably move the string to DataLayout itself since it won't be necessary anymore to represent the special case of a module without a DataLayout. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@202190 91177308-0d34-0410-b5e6-96231b3b80d8

* Refactor TargetOptions initialization into a single place.Eli Bendersky2014-02-19
| | | | | | | | | | | | | | The same code (~20 lines) for initializing a TargetOptions object from CodeGen cmdline flags is duplicated 4 times in 4 different tools. This patch moves it into a utility function. Since the CodeGen/CommandFlags.h file defines cl::opt flags in a header, it's a bit of a touchy situation because we should only link them into tools. So this patch puts the init function in the header. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@201699 91177308-0d34-0410-b5e6-96231b3b80d8

* [PM] Wire up the Verifier for the new pass manager and connect it to theChandler Carruth2014-01-20
| | | | | | | | | | | | | | | | | | | | | | various opt verifier commandline options. Mostly mechanical wiring of the verifier to the new pass manager. Exercises one of the more unusual aspects of it -- a pass can be either a module or function pass interchangably. If this is ever problematic, we can make things more constrained, but for things like the verifier where there is an "obvious" applicability at both levels, it seems convenient. This is the next-to-last piece of basic functionality left to make the opt commandline driving of the new pass manager minimally functional for testing and further development. There is still a lot to be done there (notably the factoring into .def files to kill the current boilerplate code) but it is relatively uninteresting. The only interesting bit left for minimal functionality is supporting the registration of analyses. I'm planning on doing that on top of the .def file switch mostly because the boilerplate for the analyses would be significantly worse. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@199646 91177308-0d34-0410-b5e6-96231b3b80d8
* [opt][PassInfo] Allow opt to run passes that need target machine.Quentin Colombet2014-01-16
| | | | | | | | | | | | | | | | | | | When registering a pass, a pass can now specify a second construct that takes as argument a pointer to TargetMachine. The PassInfo class has been updated to reflect that possibility. If such a constructor exists opt will use it instead of the default constructor when instantiating the pass. Since such IR passes are supposed to be rare, no specific support has been added to this commit to allow an easy registration of such a pass. In other words, for such pass, the initialization function has to be hand-written (see CodeGenPrepare for instance). Now, codegenprepare can be tested using opt: opt -codegenprepare -mtriple=mytriple input.ll git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@199430 91177308-0d34-0410-b5e6-96231b3b80d8
* [cleanup] Move the Dominators.h and Verifier.h headers into the IRChandler Carruth2014-01-13
| | | | | | | | | | | | | | | | | | directory. These passes are already defined in the IR library, and it doesn't make any sense to have the headers in Analysis. Long term, I think there is going to be a much better way to divide these matters. The dominators code should be fully separated into the abstract graph algorithm and have that put in Support where it becomes obvious that evn Clang's CFGBlock's can use it. Then the verifier can manually construct dominance information from the Support-driven interface while the Analysis library can provide a pass which both caches, reconstructs, and supports a nice update API. But those are very long term, and so I don't want to leave the really confusing structure until that day arrives. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@199082 91177308-0d34-0410-b5e6-96231b3b80d8
* [PM] Wire up support for writing bitcode with new PM.Chandler Carruth2014-01-13
| | | | | | | | | | This moves the old pass creation functionality to its own header and updates the callers of that routine. Then it adds a new PM supporting bitcode writer to the header file, and wires that up in the opt tool. A test is added that round-trips code into bitcode and back out using the new pass manager. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@199078 91177308-0d34-0410-b5e6-96231b3b80d8

* [PM] Simplify the interface exposed for IR printing passes.Chandler Carruth2014-01-12
| | | | | | | | | | | | Nothing was using the ability of the pass to delete the raw_ostream it printed to, and nothing was trying to pass it a pointer to the raw_ostream. Also, the function variant had a different order of arguments from all of the others which was just really confusing. Now the interface accepts a reference, doesn't offer to delete it, and uses a consistent order. The implementation of the printing passes haven't been updated with this simplification, this is just the API switch. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@199044 91177308-0d34-0410-b5e6-96231b3b80d8

* [PM] Add (very skeletal) support to opt for running the new passChandler Carruth2014-01-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | manager. I cannot emphasize enough that this is a WIP. =] I expect it to change a great deal as things stabilize, but I think its really important to get *some* functionality here so that the infrastructure can be tested more traditionally from the commandline. The current design is looking something like this: ./bin/opt -passes='module(pass_a,pass_b,function(pass_c,pass_d))' So rather than custom-parsed flags, there is a single flag with a string argument that is parsed into the pass pipeline structure. This makes it really easy to have nice structural properties that are very explicit. There is one obvious and important shortcut. You can start off the pipeline with a pass, and the minimal context of pass managers will be built around the entire specified pipeline. This makes the common case for tests super easy: ./bin/opt -passes=instcombine,sroa,gvn But this won't introduce any of the complexity of the fully inferred old system -- we only ever do this for the *entire* argument, and we only look at the first pass. If the other passes don't fit in the pass manager selected it is a hard error. The other interesting aspect here is that I'm not relying on any registration facilities. Such facilities may be unavoidable for supporting plugins, but I have alternative ideas for plugins that I'd like to try first. My plan is essentially to build everything without registration until we hit an absolute requirement. Instead of registration of pass names, there will be a library dedicated to parsing pass names and the pass pipeline strings described above. Currently, this is directly embedded into opt for simplicity as it is very early, but I plan to eventually pull this into a library that opt, bugpoint, and even Clang can depend on. It should end up as a good home for things like the existing PassManagerBuilder as well. There are a bunch of FIXMEs in the code for the parts of this that are just stubbed out to make the patch more incremental. A quick list of what's coming up directly after this: - Support for function passes and building the structured nesting. - Support for printing the pass structure, and FileCheck tests of all of this code. - The .def-file based pass name parsing. - IR priting passes and the corresponding tests. Some obvious things that I'm not going to do right now, but am definitely planning on as the pass manager work gets a bit further: - Pull the parsing into library, including the builders. - Thread the rest of the target stuff into the new pass manager. - Wire support for the new pass manager up to llc. - Plugin support. Some things that I'd like to have, but are significantly lower on my priority list. I'll get to these eventually, but they may also be places where others want to contribute: - Adding nice error reporting for broken pass pipeline descriptions. - Typo-correction for pass names. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@198998 91177308-0d34-0410-b5e6-96231b3b80d8

Rename the 'Assembly' include directory to 'AsmParser' to match the library name and the only functionality left their -- printing has been in the core IR library for quite some time.

* Add #pragma vectorize enable/disable to LLVMRenato Golin2013-12-05
| | | | | | | | | | | | | | | | | | | | | | | | The intended behaviour is to force vectorization on the presence of the flag (either turn on or off), and to continue the behaviour as expected in its absence. Tests were added to make sure the all cases are covered in opt. No tests were added in other tools with the assumption that they should use the PassManagerBuilder in the same way. This patch also removes the outdated -late-vectorize flag, which was on by default and not helping much. The pragma metadata is being attached to the same place as other loop metadata, but nothing forbids one from attaching it to a function (to enable #pragma optimize) or basic blocks (to hint the basic-block vectorizers), etc. The logic should be the same all around. Patches to Clang to produce the metadata will be produced after the initial implementation is agreed upon and committed. Patches to other vectorizers (such as SLP and BB) will be added once we're happy with the pass manager changes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@196537 91177308-0d34-0410-b5e6-96231b3b80d8

* Disable unrolling in the loop vectorizer when disabled in the pass managerHal Finkel2013-08-28
| | | | | | | | | | | | | | | | | When unrolling is disabled in the pass manager, the loop vectorizer should also not unroll loops. This will allow the -fno-unroll-loops option in Clang to behave as expected (even for vectorizable loops). The loop vectorizer's -force-vector-unroll option will (continue to) override the pass-manager setting (including -force-vector-unroll=0 to force use of the internal auto-selection logic). In order to test this, I added a flag to opt (-disable-loop-unrolling) to force disable unrolling through opt (the analog of -fno-unroll-loops in Clang). Also, this fixes a small bug in opt where the loop vectorizer was enabled only after the pass manager populated the queue of passes (the global_alias.ll test needed a slight update to the RUN line as a result of this fix). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@189499 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | Now that we have robust function attributes, don't use a command line option to specify the stack protecto buffer size. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186217 91177308-0d34-0410-b5e6-96231b3b80d8
* Debug Info: clean up usage of Verify.Manman Ren2013-06-28
| | | | | | | | | | | | No functionality change. It should suffice to check the type of a debug info metadata, instead of calling Verify. For cases where we know the type of a DI metadata, use assert. Also update testing cases to make them conform to the format of DI classes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@185135 91177308-0d34-0410-b5e6-96231b3b80d8

* Remove the simplify-libcalls pass (finally)Meador Inge2013-06-20
| | | | | | | | | | | This commit completely removes what is left of the simplify-libcalls pass. All of the functionality has now been migrated to the instcombine and functionattrs passes. The following C API functions are now NOPs: 1. LLVMAddSimplifyLibCallsPass 2. LLVMPassManagerBuilderSetDisableSimplifyLibCalls git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184459 91177308-0d34-0410-b5e6-96231b3b80d8
* Add DebugIR pass -- emits IR file and replace source lines with IR lines in MDDaniel Malea2013-05-08
| | | | | | | | | | | | | - requires existing debug information to be present - fixes up file name and line number information in metadata - emits a "<orig_filename>-debug.ll" succinct IR file (without !dbg metadata or debug intrinsics) that can be read by a debugger - initialize pass in opt tool to enable the "-debug-ir" flag - lit tests to follow git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181467 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | I can fix the testcases here: http://lab.llvm.org:8011/builders/clang-native-arm-cortex-a9/builds/6952 This reverts commit r179512 due to testcases specifying triples that they didn't actually mean and causing failures on other platforms. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179513 91177308-0d34-0410-b5e6-96231b3b80d8
