* Change TargetLibraryInfo analysis passes to always require FunctionTeresa Johnson2019-09-071-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This is the first change to enable the TLI to be built per-function so that -fno-builtin* handling can be migrated to use function attributes. See discussion on D61634 for background. This is an enabler for fixing handling of these options for LTO, for example. This change should not affect behavior, as the provided function is not yet used to build a specifically per-function TLI, but rather enables that migration. Most of the changes were very mechanical, e.g. passing a Function to the legacy analysis pass's getTLI interface, or in Module level cases, adding a callback. This is similar to the way the per-function TTI analysis works. There was one place where we were looking for builtins but not in the context of a specific function. See FindCXAAtExit in lib/Transforms/IPO/GlobalOpt.cpp. I'm somewhat concerned my workaround could provide the wrong behavior in some corner cases. Suggestions welcome.

* [webassembly] Apply llvm-prefer-register-over-unsigned from clang-tidy to LLVMDaniel Sanders2019-08-121-2/+2
| | | | | | | | | | | | | | | | | Summary: This clang-tidy check is looking for unsigned integer variables whose initializer starts with an implicit cast from llvm::Register and changes the type of the variable to llvm::Register (dropping the llvm:: where possible).

* [WebAssembly] Implement tail calls and unify tablegen call classesThomas Lively2019-06-261-2/+2
| | | | | | | | | | | | | | | | | Summary: Implements direct and indirect tail calls enabled by the 'tail-call' feature in both DAG ISel and FastISel. Updates existing call tests and adds new tests including a binary encoding test.

* [WebAssembly] clang-tidy (NFC)Heejin Ahn2019-02-041-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This patch fixes clang-tidy warnings on wasm-only files. The list of checks used is: `-*,clang-diagnostic-*,llvm-*,misc-*,-misc-unused-parameters,readability-identifier-naming,modernize-*` (LLVM's default .clang-tidy list is the same except it does not have `modernize-*`. But I've seen in multiple CLs in LLVM the modernize style was recommended and code was fixed based on the style, so I added it as well.) The common fixes are: - Variable names start with an uppercase letter - Function names start with a lowercase letter - Use `auto` when you use casts so the type is evident - Use inline initialization for class member variables - Use `= default` for empty constructors / destructors - Use `using` in place of `typedef` Reviewers: sbc100, tlively, aardappel Subscribers: dschuff, sunfish, jgravelle-google, yurydelendik, kripken, MatzeB, mgorny, rupprecht, llvm-commits Differential Revision: https://reviews.llvm.org/D57500 llvm-svn: 353075
* Update the file headers across all of the LLVM projects in the monorepoChandler Carruth2019-01-191-4/+3
| | | | | | | | | | | | | | | | | to reflect the new license. We understand that people may be surprised that we're moving the header entirely to discuss the new license. We checked this carefully with the Foundation's lawyer and we believe this is the correct approach. Essentially, all code in the project is now made available by the LLVM project under our new license, so you will see that the license headers include that license only. Some of our contributors have contributed code under our old license, and accordingly, we have retained a copy of our old license notice in the top-level files in each project and repository. llvm-svn: 351636
* [WebAssembly] Rename StoreResults to MemIntrinsicResultsHeejin Ahn2019-01-081-0/+212
Summary: StoreResults pass does not optimize store instructions anymore because store instructions don't return results values anymore. Now this pass is used solely for memory intrinsics, so update the pass name accordingly and fix outdated pass descriptions as well. This patch does not change any meaningful behavior, but not marked as NFC because it changes a comment check line in a test case.
