* ELF: Add a skip() overload to ignore any tokenJustin Bogner2016-10-173-9/+20
| | | | | | | | | Most functions that return StringRef should check their return values, so I'm planning on marking StringRef [[nodiscard]]. This requires splitting up functions like next() that are sometimes just used for side effects. llvm-svn: 284363
* Interpreter: Don't return StringRef from functions whose return value is ↵Justin Bogner2016-10-172-31/+16
| | | | | | | | | | never used StringRef is passed through all of these APIs but never actually used. Just remove it from the API for now and if people want to use it they can add it back. llvm-svn: 284362
* ELF: Fix a misuse of Twine::toStringRefJustin Bogner2016-10-171-3/+3
| | | | | | | | While the toStringRef API almost certainly ends up populating the SmallString here, the correct way to use this API is to use the return value. llvm-svn: 284361

* [CUDA] Fix false-positive in known-emitted handling.Justin Lebar2016-10-172-6/+66
| | | | | | | | | | | | | | | | | Previously: When compiling for host, our constructed call graph went *through* kernel calls. This meant that if we had host calls kernel calls HD we would incorrectly mark the HD function as known-emitted on the host side, and thus perform host-side checks on it. Fixing this exposed another issue, wherein when marking a function as known-emitted, we also need to traverse the callgraph of its template, because non-dependent calls are attached to a function's template, not its instantiation. llvm-svn: 284355

| | | | | | | | | redeclarations"" This reverts commit r284340 to reapply r284335. The bot breakage was due to an unrelated change in the polybench test suite. llvm-svn: 284351
* unittests: Explicitly ignore some return values in crash testsJustin Bogner2016-10-161-16/+18
| | | | | | | | Ideally these would actually check that the results are reasonable, but given that we're looping over so many different kinds of path that isn't really practical. llvm-svn: 284350

* Support: Return void from Scanner::scan_ns_uri_char, no one uses the resultJustin Bogner2016-10-161-7/+2
| | | | | | | Simplify this a little bit since the result is never used. It can be added back easily enough if that changes. llvm-svn: 284348
* [cmake] Add polly-isl-test dependency to lit tests.Michael Kruse2016-10-161-1/+1
| | | | | | Also handle the in-llvm-tree case forgotten in r284339. llvm-svn: 284347
* MachineModuleInfo: Prefer the LLVM_NODISCARD spellingJustin Bogner2016-10-161-2/+1

| | | | | | | Update functions annotated with LLVM_ATTRIBUTE_UNUSED_RESULT to use LLVM_NODISCARD instead. llvm-svn: 284343
* ADT: Use LLVM_NODISCARD instead of LLVM_ATTRIBUTE_UNUSED_RESULT for ArrayRefJustin Bogner2016-10-161-14/+2
| | | | | | | Instead of annotating (most of) the ArrayRef API, we can just annotate the type directly. This is less code and it will warn in more cases. llvm-svn: 284342
* AST: Improve a couple of comments and cast unused values to voidJustin Bogner2016-10-161-5/+4
| | | | | | | | Make these comments a bit more explicit that they're initializing the RawText member, and explicitly cast the unused result of getRawText to void for clarity. llvm-svn: 284341
* Revert "[analyzer] Make MallocChecker more robust against custom redeclarations"Devin Coughlin2016-10-162-36/+0
| | | | | | | | | | This reverts commit r284335. It appears to be causing test-suite compile-time and execution-time performance measurements to take longer than expected on several bots. This is surprising, because r284335 is a static-analyzer-only change. llvm-svn: 284340
* [cmake] Add polly-isl-test dependency to lit tests.Michael Kruse2016-10-161-1/+1
| | | | | | | | | | | lit recursively iterates through the test subdirectories and finds the ISL unittest. For this test to work, the polly-isl-test executable needs to be compiled. Add the polly-isl-test dependency to POLLY_TEST_DEPS. This makes check-polly and check-polly-tests work from a fresh build directory. llvm-svn: 284339
* [test] Add -polly-unprofitable-scalar-accs to test that needs it.Michael Kruse2016-10-161-0/+1
| | | | | | | | The test non_affine_loop_used_later.ll also tests the profability heuristic. Add the option -polly-unprofitable-scalar-accs explicitely to ensure that the test succeeds if the default value is changed. llvm-svn: 284338
* P0012R1: Make exception specifications be part of the type system. ThisRichard Smith2016-10-1629-85/+445

* [analyzer] Make MallocChecker more robust against custom redeclarationsDevin Coughlin2016-10-162-0/+36
| | | | | | | | | | | | | Add additional checking to MallocChecker to avoid crashing when memory routines have unexpected numbers of arguments. You wouldn't expect to see much of this in normal code (-Wincompatible-library-redeclaration warns on this), but, for example, CMake tests can generate these. This is PR30616. rdar://problem/28631974 llvm-svn: 284335

| | | | | | | | | | | In theory this could be generalized to move anything where we prove the operands are available, but that would require rewriting PRE. As NewGVN will hopefully come soon, and we're trying to rewrite PRE in terms of NewGVN+MemorySSA, it's probably not worth spending too much time on it. Fix provided by Daniel Berlin! llvm-svn: 284311
