2013-01-22Implements more principled comment parsing.Manuel Klimek
Changing nextToken() in the UnwrappedLineParser to get the next non-comment token. This allows us to correctly layout a whole class of snippets, like: if /* */(/* */ a /* */) /* */ f() /* */; /* */ else /* */ g(); Fixes a bug in the formatter where we would assume there is a previous non-comment token. Also adds the indent level of an unwrapped line to the debug output in the parser. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173168 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-22Switch to APFloat constructor taking fltSemantics.Tim Northover
This change also makes the serialisation store the required semantics, fixing an issue where PPC128 was always assumed when re-reading a 128-bit value. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173139 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-22[ASan] Link with the dynamic runtime on OS XAlexander Potapenko
This patch changes the behavior of the -fsanitize=address flag, making it use the dynamic runtime library (libclang_rt.asan_osx_dynamic.dylib) instead of the static one. It also drops the CoreFoundation dependency, since the dynamic runtime doesn't need it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173135 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-22Use the correct field to copy/dispose a __block variable.John McCall
We were previously hard-coding a particular field index. This was fine before (because we were obviously guaranteed the presence of a copy/dispose member) except for (1) alignment padding and (2) future extensions adding extra members to the header, such as the extended-layout pointer. Note that we only introduce the extended-layout pointer in the presence of structs. (We also seem to be introducing it even in the presence of an all-non-object layout, but that's a different potential issue.) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173122 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-21Make AttributeSet::getFnAttributes() return an AttributeSet instead of an ↵Bill Wendling

2013-01-21Give ModuleFiles an index, so that we can use indexed vectors ratherDouglas Gregor
than DenseMaps and SmallPtrSets for module-visitation data. ~2.6% speedup for modules. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173081 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-21Eliminate Sema::CompareProperties(), which was walking over a pile ofDouglas Gregor
lexical declarations looking for properties when we could more efficiently check for property mismatches at property declaration time. Good for ~1% of -fsyntax-only time when most of the properties we're checking against come from an AST file. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173079 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-21Fixes various problems around enum parsing.Manuel Klimek
Very similar to what we do for record definitions: - tighten down what is an enum definition, so that we don't mistake a function for an enum - allow common idioms around declarations (we'll want to handle that more centrally in the future) We now correctly format: enum X f() { a(); return 42; } git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173075 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-21Eliminate the oddly-named Sema::ComparePropertiesInBaseAndSuper, whichDouglas Gregor
did a redundant traversal of the lexical declarations in the superclass. Instead, when we declare a new property, look into the superclass to see whether we're redeclaring the property. Goot for 1% of -fsyntax-only time on Cocoa.h and a little less than 3% on my modules test case. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173073 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-21When loading an identifier from an AST file solely for the purpose ofDouglas Gregor
forming the identifier, e.g., as part of a selector or a declaration name, don't actually deserialize any information about the identifier. Instead, simply mark it "out-of-date" and we'll load the the information on demand. 2% speedup on the modules testcase I'm looking at; should also help PCH. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173056 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-21Fixes formatting of empty blocks.Manuel Klimek
We now only put empty blocks into a single line, if all of: - all tokens of the structural element fit into a single line - we're not in a control flow statement Note that we usually don't put record definitions into a single line, as there's usually at least one more token (the semicolon) after the closing brace. This doesn't hold when we are in a context where there is no semicolon, like "enum E {}". There were some missing tests around joining lines around the corner cases of the allowed number of columns, so this patch adds some. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173055 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-21When deserializing a declaration, don't look for redeclarations if itsDouglas Gregor
kind indicates that it can never be redeclared. Good for a 1% speedup, and redeclaration searching drops off the profile. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173054 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-21Introduce a fast path for the ASTReader's name lookup within aDouglas Gregor
DeclContext. When the DeclContext is of a kind that can only be defined once and never updated, we limit the search to the module file that conatins the lookup table. Provides a 15% speedup in one modules-heavy source file. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173050 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-21PR14472: Preserve qualifiers while unwrapping types for debug infoDavid Blaikie
Looks like r161368 fixed this for one case but not all. This change generalizes the solution over all the unwrapping cases. Now that preserving the qualifiers is done independent of the particular type being unwrapped I won't bother adding test cases for each one but at least demonstrate that this change was necessary & sufficient to fix the bug. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173002 91177308-0d34-0410-b5e6-96231b3b80d8
