2013-02-02Sentenc-ify comment added in r174206.David Blaikie
Based on post-commit review by Paul Robinson. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174248 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-02Generalize DebugInfo tests by avoiding explicit metadata numbersDavid Blaikie
This addresses several (not all) debug info tests that use explicit metadata numbers. Wherever the same number appeared more than once in a test I used a named match to ensure the same number appeared in all those cases (this may still be overly constraining test cases as they may not have actually cared about that relationship). For one-off numbers I just replaced them with an unnamed regex. This may underconstrain poorly written test cases that were interested in checking that certain metadata nodes were related but didn't actually match on all the related nodes numbers. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174247 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-02[analyzer] Always inline functions with bodies generated by BodyFarm.Anna Zaks
Inlining these functions is essential for correctness. We often have cases where we do not inline calls. For example, the shallow mode and when reanalyzing previously inlined ObjC methods as top level. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174245 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-02This patch makes "&Cls::purevfn" not an odr use. This isn't what the standardNick Lewycky
says, but that's a defect (to be filed). "Cls::purevfn()" is still an odr use. Also fixes a bug that caused us to not mark the function referenced just because we didn't want to mark it odr used. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174242 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-01Merge "special" types from different modules in the AST reader.Douglas Gregor
Different modules may have different views of the various "special" types in the AST, such as the redefinition type for "id".

2013-02-01Re-apply "[analyzer] Model trivial copy/move ctors with an aggregate bind."Jordan Rose
With the optimization in the previous commit, this should be safe again. Originally applied in r173951, then reverted in r174069. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174212 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-01[analyzer] Reuse a LazyCompoundVal if its type matches the new region.Jordan Rose
This allows us to keep from chaining LazyCompoundVals in cases like this: CGRect r = CGRectMake(0, 0, 640, 480); CGRect r2 = r; CGRect r3 = r2; Previously we only made this optimization if the struct did not begin with an aggregate member, to make sure that we weren't picking up an LCV for the first field of the struct. But since LazyCompoundVals are typed, we can make that inference directly by comparing types. This is a pure optimization; the test changes are to guard against possible future regressions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174211 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-01Fix exception handling line table problems introduced by r173593David Blaikie
r173593 made us a little too eager to associate all code at the end of a function with the user-written 'return' line. This caused problems with breakpoints as they'd be set in exception handling code preceeding the actual non-exception return handling code, leading to the breakpoint never being hit in non-exceptional execution. This change restores the pre-r173593 exception handling line information where the cleanup code is associated with the '}' not the return line. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174206 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-01Fix PR14881 by implementing conversion rules between int and complex int.Bill Schmidt
Prior to the patch, Clang does not properly promote types when a complex integer operand is combined with an integer via a binary operator, or when one is assigned to the other in either order. This patch detects when promotion is needed (and permissible) and generates the necessary code. The test assmes no target has the same size operands for "char" and "long long," and that no target performs arithmetic on char operands without extending them to a larger format first. If there are any targets for which this is not the case, they should be XFAILed. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174181 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-01Re-design the convenience interfaces on MatchFinder.Manuel Klimek
First, this implements a match() method on MatchFinder; this allows us to get rid of the findAll implementation, as findAll is really a special case of recursive matchers on match. Instead of findAll, provide a convenience function match() that lets users iterate easily over the results instead of needing to implement callbacks. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174172 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-01Revamp of the basic layouting algorithm in clang-format.Daniel Jasper
In order to end up with good solutions, clang-format needs to try "all" combinations of line breaks, evaluate them and select the best one. Before, we have done this using a DFS with memoization and cut-off conditions. However, this approach is very limited as shown by the huge static initializer in the attachment of llvm.org/PR14959. Instead, this new implementation uses a variant of Dijkstra's algorithm to do a prioritized BFS over the solution space. Some numbers: lib/Format/TokenAnnotator.cpp: 1.5s -> 0.15s Attachment of PR14959: 10min+ (didn't finish) -> 10s No functional changes intended. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174166 91177308-0d34-0410-b5e6-96231b3b80d8

Introduces these negation forms explicitly and uses them to control a new "altivec" target feature for PowerPC.
