* [analyzer] Don't display implementation checkers under ↵Kristof Umann2019-05-0113-40/+103
| | | | | | | | | | | | | | | | | | | | | | | -analyzer-checker-help, but do under the new flag -analyzer-checker-help-hidden During my work on analyzer dependencies, I created a great amount of new checkers that emitted no diagnostics at all, and were purely modeling some function or another. However, the user shouldn't really disable/enable these by hand, hence this patch, which hides these by default. I intentionally chose not to hide alpha checkers, because they have a scary enough name, in my opinion, to cause no surprise when they emit false positives or cause crashes. The patch introduces the Hidden bit into the TableGen files (you may remember it before I removed it in D53995), and checkers that are either marked as hidden, or are in a package that is marked hidden won't be displayed under -analyzer-checker-help. -analyzer-checker-help-hidden, a new flag meant for developers only, displays the full list.

* Make check-clang depend on the clang-check binary alwaysNico Weber2019-05-012-4/+6
| | | | | | | | | | | | | | | | | check-clang (the target that runs all clang tests) used to only depend on clang-check (a binary like clang-tidy, clang-refactor, etc) if the static analyzer is enabled. However, several lit tests call clang-check unconditionally, so always depend on it. Fixes a "could not find clang-check" lit warning in clean builds with the static analyzer disabled. Also sort the deps in the CMake file and put just one dep on each line. Differential Revision: https://reviews.llvm.org/D61324 llvm-svn: 359717
* Enable OpenMP build for 32-bit FreeBSDDimitry Andric2019-05-011-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | Summary: To be able to successfully build OpenMP on 32-bit FreeBSD, such as FreeBSD/i386, I first had to provide a few wrappers (see D60916), and then add `KMP_OS_FREEBSD` to the list of defines checked for 32-bit architectures in `kmp_runtime.cpp`. I have successfully built libomp.so and ran a bunch of test programs on FreeBSD/i386 with this.

* [Parser] Avoid correcting delayed typos in array subscript multiple times.Volodymyr Sapsai2019-05-013-8/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | We correct some typos in `ActOnArraySubscriptExpr` and `ActOnOMPArraySectionExpr`, so when their result is `ExprError`, we can end up correcting delayed typos in the same expressions again. In general it is OK but when `NumTypos` is incorrect, we can hit the assertion > Assertion failed: (Entry != DelayedTypos.end() && "Failed to get the state for a TypoExpr!"), function getTypoExprState, file clang/lib/Sema/SemaLookup.cpp, line 5219. Fix by replacing some subscript `ExprResult` with typo-corrected expressions instead of keeping the original expressions. Thus if original expressions contained `TypoExpr`, we'll use corrected expressions instead of trying to correct them again. rdar://problem/47403222 Reviewers: rsmith, erik.pilkington, majnemer Reviewed By: erik.pilkington Subscribers: jkorous, dexonsmith, cfe-commits Differential Revision: https://reviews.llvm.org/D60848 llvm-svn: 359713

* [OpenMP] Implement task modifier for reduction clauseJonathan Peyton2019-05-017-57/+757
| | | | | | | | | | | | | | | | | Implemented task modifier in two versions - one without taking into account omp_orig variable (the omp_orig still can be processed by compiler without help of the library, but each reduction object will need separate initializer with global access to omp_orig), another with omp_orig variable included into interface (single initializer can be used for multiple reduction objects of the same type). Second version can be used when the omp_orig is not globally accessible, or to optimize code in case of multiple reduction objects of the same type.

* Option spell checking: Penalize delimiter flags if input has no argumentNico Weber2019-05-013-5/+26
| | | | | | | | | | | | | | | If the user passes a flag like `-version` to a program, it's more likely they mean `--version` than `-version:`, since there's no parameter passed. Hence, give delimited arguments a penalty of 1 if the user input doesn't contain the delimiter or no data after it. The motivation is that with this, lld-link can suggest "--version" instead of "-version:" for "-version" and "-nodefaultlib" instead of "-nodefaultlib:" for "-nodefaultlibs".

As per POSIX.1-2017 XCU Section 1.4, Utility Description Defaults, "[the] format of diagnostic messages for most utilities is unspecified". The STDERR subsections of the `cat` and `wc` utilities merely indicate that "[the] standard error shall be used only for diagnostic messages". The corresponding EXIT STATUS subsections merely indicate, with regard to errors, an exit value of >0.

What remained was the performance issue in setLoopID where it would iterate through all blocks in the loop and their successors, rather than just the predecessor of the header (the later presumably being much faster).

* DAG: allow DAG pointer size different from memory representation.Tim Northover2019-05-017-48/+178
| | | | | | | | | | | | | | | | | | | | | In preparation for supporting ILP32 on AArch64, this modifies the SelectionDAG builder code so that pointers are allowed to have a larger type when "live" in the DAG compared to memory. Pointers get zero-extended whenever they are loaded, and truncated prior to stores. In addition, a few not quite so obvious locations need updating: * A GEP that has not been marked inbounds needs to enforce the IR-documented 2s-complement wrapping at the memory pointer size. Inbounds GEPs are undefined if they overflow the address space, so no additional operations are needed. * Signed comparisons would give incorrect results if performed on the zero-extended values. This shouldn't affect CodeGen for now, but will become active when the AArch64 ILP32 support is committed. llvm-svn: 359676
