2012-07-13Add a per target max vector alignment field (e.g., 32-byte alignment for x86 ↵Chad Rosier
due to AVX). Currently, if no aligned attribute is specified the alignment of a vector is inferred from its size. Thus, very large vectors will be over-aligned with no benefit. Target owners should set this target max. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@160209 91177308-0d34-0410-b5e6-96231b3b80d8

2012-07-13This is one of the first steps at moving to replace target-dependent Joel Jones
intrinsics with target-indepdent intrinsics. The first instruction(s) to be handled are the vector versions of count leading zeros (ctlz). The changes here are to clang so that it generates a target independent vector ctlz when it sees an ARM dependent vector ctlz. The changes in llvm are to match the target independent vector ctlz and in VMCore/AutoUpgrade.cpp to update any existing bc files containing ARM dependent vector ctlzs with target-independent ctlzs. There are also changes to an existing test case in llvm for ARM vector count instructions and a new test for the bitcode upgrade. <rdar://problem/11831778> There is deliberately no test for the change to clang, as so far as I know, no consensus has been reached regarding how to test neon instructions in clang; q.v. <rdar://problem/8762292> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@160201 91177308-0d34-0410-b5e6-96231b3b80d8

2012-07-12[analyzer] Don't inline virtual calls unless we can devirtualize properly.Jordan Rose
Previously we were using the static type of the base object to inline methods, whether virtual or non-virtual. Now, we try to see if the base object has a known type, and if so ask for its implementation of the method. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@160094 91177308-0d34-0410-b5e6-96231b3b80d8

2012-07-11Enable comment parsing and semantic analysis to emit diagnostics. A fewDmitri Gribenko
diagnostics implemented -- see testcases. I created a new TableGen file for comment diagnostics, DiagnosticCommentKinds.td, because comment diagnostics don't logically fit into AST diagnostics file. But I don't feel strongly about it. This also implements support for self-closing HTML tags in comment lexer and parser (for example, <br />). In order to issue precise diagnostics CommentSema needs to know the declaration the comment is attached to. There is no easy way to find a decl by comment, so we match comments and decls in lockstep: after parsing one declgroup we check if we have any new, not yet attached comments. If we do -- then we do the usual comment-finding process. It is interesting that this automatically handles trailing comments. We pick up not only comments that precede the declaration, but also comments that *follow* the declaration -- thanks to the lookahead in the lexer: after parsing the declgroup we've consumed the semicolon and looked ahead through comments. Added -Wdocumentation-html flag for semantic HTML errors to allow the user to disable only HTML warnings (but not HTML parse errors, which we emit as warnings in -Wdocumentation). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@160078 91177308-0d34-0410-b5e6-96231b3b80d8
2012-07-11Introduce a flag in SourceManager to treat non-system source filesArgyrios Kyrtzidis
as "volatile", meaning there's a high enough chance that they may change while we are trying to use them. This flag is only enabled by libclang. Currently "volatile" source files will be stat'ed immediately before opening them, because the file size stat info may not be accurate since when we got it (e.g. from the PCH). This avoids crashes when trying to reference mmap'ed memory from a file whose size is not what we expect. Note that there's still a window for a racing issue to occur but the window for it should be way smaller than before. We can consider later on to avoid mmap completely on such files. rdar://11612916 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@160074 91177308-0d34-0410-b5e6-96231b3b80d8
2012-07-11Allow -verify directives to be filtered by preprocessing.Jordan Rose
This is accomplished by making VerifyDiagnosticsConsumer a CommentHandler, which then only reads the -verify directives that are actually in live blocks of code. It also makes it simpler to handle -verify directives that appear in header files, though we still have to manually reparse some files depending on how they are generated. This requires some test changes. In particular, all PCH tests now have their -verify directives outside the "header" portion of the file, using the @line syntax added in r159978. Other tests have been modified mostly to make it clear what is being tested, and to prevent polluting the expected output with the directives themselves. Patch by Andy Gibbs! (with slight modifications) The new Frontend/verify-* tests exercise the functionality of this commit, as well as r159978, r159979, and r160053 (Andy's other -verify enhancements). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@160068 91177308-0d34-0410-b5e6-96231b3b80d8

2012-07-11Emit -verify diagnostics even when we have a fatal error.Jordan Rose
Previously we'd halt at the fatal error as expected, but not actually emit any -verify-related diagnostics. This lets us catch cases that emit a /different/ fatal error from the one we expected. This is implemented by adding a "force emit" mode to DiagnosticBuilder, which will cause diagnostics to immediately be emitted regardless of current suppression. Needless to say this should probably be used /very/ sparingly. Patch by Andy Gibbs! Tests for all of Andy's -verify patches coming soon. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@160053 91177308-0d34-0410-b5e6-96231b3b80d8

2012-07-10[analyzer] Add debug.DumpCalls, which prints out any CallEvents it sees.Jordan Rose
This is probably not so useful yet because it is not path-sensitive, though it does try to show inlining with indentation.

2012-07-10[analyzer] Use CallEvent for building inlined stack frames.Jordan Rose
In order to accomplish this, we now build the callee's stack frame as part of the CallEnter node, rather than the subsequent BlockEdge node. This should not have any effect on perceived behavior or diagnostics. This makes it safe to re-enable inlining of member overloaded operators. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@160022 91177308-0d34-0410-b5e6-96231b3b80d8
