* Fix combining pragma __debug dump & parser_crash with -EDavid Blaikie2018-11-151-4/+0
| | | | | | | | | | | | | | | | | | | | | | | Previously these would be transformed into annotation tokens and the preprocessor would then assume they were real tokens with source locations and assert/UB. Other pragmas that produce annotation tokens aren't a problem because they aren't handled if the parser isn't hooked up - ParsePragma.cpp registers those handlers & isn't run for pure preprocessing. So they're treated as unknown pragmas & printed verbatim by the preprocessor. Perhaps these pragmas should be treated the same way? But they got mixed in with other __debug pragmas that do need to be handled during preprocessing. The third __debug pragma that produces an annotation token is 'captured' - which had its own fix for this issue - by not inserting the annotation token in the first place if it detected that it was in preprocessing mode. I've removed that fix (from Lex/Pragma.cpp) in favor of the more general one in Frontend/PrintPreprocessedOutput.cpp. llvm-svn: 346928

The fix is actually correct, we will reland it after figuring out how to integrate properly. llvm-svn: 345963
* Fix clang -Wimplicit-fallthrough warnings across llvm, NFCReid Kleckner2018-11-011-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch should not introduce any behavior changes. It consists of mostly one of two changes: 1. Replacing fall through comments with the LLVM_FALLTHROUGH macro 2. Inserting 'break' before falling through into a case block consisting of only 'break'. We were already using this warning with GCC, but its warning behaves slightly differently. In this patch, the following differences are relevant: 1. GCC recognizes comments that say "fall through" as annotations, clang doesn't 2. GCC doesn't warn on "case N: foo(); default: break;", clang does 3. GCC doesn't warn when the case contains a switch, but falls through the outer case. I will enable the warning separately in a follow-up patch so that it can be cleanly reverted if necessary.

We append "foo" to each directory on the include path, and then list its files. Completions are of the forms: #include <somedir/fo^ foo.h> fox/ The filter is set to the filename part ("fo"), so fuzzy matching can be applied to the filename only. No fancy scoring/priorities are set, and no information is added to CodeCompleteResult to make smart scoring possible. Could be in future.

| | | | | | | | | | | | | | | | | | | | | | | Summary: Most callers I can find are using only `getName()`. Type is used by the recursive iterator. Now we don't have to call stat() on every listed file (on most platforms). Exceptions are e.g. Solaris where readdir() doesn't include type information. On those platforms we'll still stat() - see D51918. The result is significantly faster (stat() can be slow). My motivation: this may allow us to improve clang IO on large TUs with long include search paths. Caching readdir() results may allow us to skip many stat() and open() operations on nonexistent files.

Assuming that files are usually logically named and start and end with an alphanumeric character, we can check for the file's existence by stripping the non-alphanumeric leading or trailing characters.

| | | | | | | | | | | | | | | | | | | C++2a via http://wg21.link/p0355 permits the library literals of 'd' and 'y'. This patch enables them in the Lexer so that they can be properly parsed. Note that 'd' gets confused with the hex character, so modifications to how octal, binary, and decimal numbers are parsed were required. Since this is simply making previously invalid code legal, this should be fine. Hex still greedily parses the 'd' as a hexit, since it would a: violate [lex.ext]p1 b: break existing code.

| | | | | | | | | | | | | | | | as fixed point literals This addresses a bug brought up in https://bugs.llvm.org/show_bug.cgi?id=38161 where integer literals could be treated as fixed point types and throw errors related to fixed point types when the 'k' or 'r' suffix used. The fix also addresses the second issue brought up with the assertion by not treating integers as fixed point types in the first place. Integers that have suffixes 'k' and 'r' now throw the error `invalid suffix 'k/r' on integer constant`. A few more tests were also added to ensure that fixed point types, and any errors/warnings related to them, are limited to C for now. Prior discussion also at https://reviews.llvm.org/D46915.

* Warning for framework include violation from Headers to PrivateHeadersBruno Cardoso Lopes2018-06-251-5/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | Framework vendors usually layout their framework headers in the following way: Foo.framework/Headers -> "public" headers Foo.framework/PrivateHeader -> "private" headers Since both headers in both directories can be found with #import <Foo/some-header.h>, it's easy to make mistakes and include headers in Foo.framework/PrivateHeader from headers in Foo.framework/Headers, which usually configures a layering violation on Darwin ecosystems. One of the problem this causes is dep cycles when modules are used, since it's very common for "private" modules to include from the "public" ones; adding an edge the other way around will trigger cycles. Add a warning to catch those cases such that: ./A.framework/Headers/A.h:1:10: warning: public framework header includes private framework header 'A/APriv.h' #include <A/APriv.h> ^ rdar://problem/38712182 llvm-svn: 335542

* Remove \brief commands from doxygen comments.Adrian Prantl2018-05-0913-87/+87
| | | | | | | | | | | | | | | | | | | This is similar to the LLVM change https://reviews.llvm.org/D46290. We've been running doxygen with the autobrief option for a couple of years now. This makes the \brief markers into our comments redundant. Since they are a visual distraction and we don't want to encourage more \brief markers in new code either, this patch removes them all.

* Implement P0482R2, support for char8_t type.Richard Smith2018-05-011-1/+1
| | | | | | | | | | | | This is not yet part of any C++ working draft, and so is controlled by the flag -fchar8_t rather than a -std= flag. (The GCC implementation is controlled by a flag with the same name.) This implementation is experimental, and will be removed or revised substantially to match the proposal as it makes its way through the C++ committee. llvm-svn: 331244
* IWYU for llvm-config.h in clang. See r331124 for details.Nico Weber2018-04-301-1/+0
