* clang-format: Improve nested block / lambda indentation when wrappingDaniel Jasper2015-05-131-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | before binary/ternary operators. Basically, it doesn't seem right to indent a nested block aligned to a binary or ternary operator. Before: int i = aaaaaa ? 1 // : [] { return 2; // }(); llvm::errs() << "number of twos is " << std::count_if(v.begin(), v.end(), [](int x) { return x == 2; // force break }); After: int i = aaaaaa ? 1 // : [] { return 2; // }(); llvm::errs() << "number of twos is " << std::count_if(v.begin(), v.end(), [](int x) { return x == 2; // force break }); llvm-svn: 237263

* Add a new error for unexpected semi-colon before closing delimiter.Richard Trieu2015-05-121-1/+7
| | | | | | | | | Previously, if a semi-colon is unexpectedly added before a closing ')', ']' or '}', two errors and one note would emitted, and the parsing would get confused to which scope it was in. This change consumes the semi-colon, recovers parsing better, and emits only one error with a fix-it. llvm-svn: 237192

* Fixed double-free in case of module loading error.Artem Belevich2015-05-121-2/+2
| | | | | | | | | | | | | GetOutputStream() owns the stream it returns pointer to and the pointer should never be freed by us. When we fail to load and exit early, unique_ptr still holds the pointer and frees it which leads to compiler crash when CompilerInstance attempts to free it again. Added regression test for failed bitcode linking. Differential Revision: http://reviews.llvm.org/D9625 llvm-svn: 237159

* Refactor clang-format's formatter.Manuel Klimek2015-05-122-164/+220
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: a) Pull out a class LevelIndentTracker whose responsibility is to keep track of the indent of levels across multiple annotated lines. b) Put all responsibility for merging lines into the LineJoiner; make the LineJoiner iterate over the lines so we never operate on a line that might be merged later; this makes the interface safer to use. c) Move formatting of the end-of-file whitespace into formatFirstToken. Fix bugs that became obvious after the refactoring: 1. We would not format lines with offsets correctly inside nested blocks if only the outer expression was affected: int x = s({ // clang-format only this line class X { public: // ^ this starts at the non-modified indnent level; previously we would // not fix this, now we correctly outdent it. void f(); }; }); 2. We would incorrectly align comments across lines that do not have comments for lines with nested blocks: int expression; // with comment int x = s({ int y; // comment int z; // we would incorrectly align this comment with the comment on // 'expression' }); llvm-svn: 237104

| | | | | | 'schedule' clause for combined directives requires additional processing. Special helper variable is generated, that is captured in the outlined parallel region for 'parallel for' region. This captured variable is used to store chunk expression from the 'schedule' clause in this 'parallel for' region. llvm-svn: 237100
* Driver: Fix a -Wshadow issue from r237091Justin Bogner2015-05-122-3/+8
| | | | | | | | | | The MachO toolchain has an isTargetIOSBased method, but it isn't virtual so it isn't very meaningful to call it. After thinking about this, I guess that putting this logic in the MachO class is a bit of a layering violation anyway. Do this more like how we handle AddLinkRuntimeLibArgs instead. llvm-svn: 237095

* Driver: Make profiling flags work with -nostdlib on DarwinJustin Bogner2015-05-123-14/+30
| | | | | | | | | | | | | Compiler-rt's Profiling library isn't part of the stdlib, so -nostdlib shouldn't prevent it from being linked. This makes Darwin behave like other toolchains, and link in the profile runtime irrespective of -nostdlib, since the resulting program can't be run unless you link this. I've also added a test to show that other toolchains already behave like this. llvm-svn: 237074
* Allow empty assembly string literal with -fno-gnu-inline-asmSteven Wu2015-05-122-8/+18
| | | | | | | | | Empty assembly string will not introduce assembly code in the output binary and it is often used as a trick in the header to disable optimizations. It doesn't conflict with the purpose of the option so it is allowed with -fno-gnu-inline-asm flag. llvm-svn: 237073

* Allow AsmLabel with -fno-gnu-inline-asmSteven Wu2015-05-111-4/+5
| | | | | | | | | | | | | | | | | | | Summary: AsmLabel is heavily used in system level and firmware to redirect function and access platform specific labels. They are also extensively used in system headers which makes this option unusable for many users. Since AsmLabel doesn't introduce any assembly code into the output binary, it shouldn't be considered as inline-asm.

* [MS ABI] Form member pointers from virtual funcs overriding vbasesDavid Majnemer2015-05-101-12/+13
| | | | | | | | | | | | | | | We didn't supporting taking the address of virtual member functions which overrode a method in a virtual base. We simply need to encode the virtual base index in the member pointer. This fixes PR23452. N.B. There is no data member pointer side to this change because taking the address of a virtual bases' data member gives you a member pointer whose type is derived from the virtual bases' type, not the most derived type. llvm-svn: 236962
* [MS ABI] Update EH emission for MSVC 2015 compatibilityDavid Majnemer2015-05-101-1/+4
| | | | | | | | | | | | | MSVC 2015 renamed the symbol found by name lookup for 'std::terminate' so we cannot rely on using '?terminate@@YAXXZ'. Furthermore, it seems that 2015 will be the first release of MSVC which permits inlining a function which is noexcept into a function which isn't. This is implemented by creating a cleanup for the invoker which jumps to __std_terminate. Clang's implementation of this aspect of the MSVC scheme is slightly less efficient in this respect because we use a catch handler configured as a catch-all handler instead. llvm-svn: 236961
