2013-02-01Comment parsing: improve the fidelity of XML output for many block commandsDmitri Gribenko
This change introduces a 'kind' attribute for the <Para> tag, that captures the kind of the parent block command.

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

2013-02-01Re-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

2013-02-01Enable -fno-altivec, -mno-altivec for PowerPC.Bill Schmidt
Introduces these negation forms explicitly and uses them to control a new "altivec" target feature for PowerPC. This allows avoiding generating Altivec instructions on processors that support Altivec. The new test case verifies that the Altivec "lvx" instruction is not used when -fno-altivec is present on the command line. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174140 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-30[analyzer] Make shallow mode more shallow.Anna Zaks
Redefine the shallow mode to inline all functions for which we have a definite definition (ipa=inlining). However, only inline functions that are up to 4 basic blocks large and cut the max exploded nodes generated per top level function in half. This makes shallow faster and allows us to keep inlining small functions. For example, we would keep inlining wrapper functions and constructors/destructors. With the new shallow, it takes 104s to analyze sqlite3, whereas the deep mode is 658s and previous shallow is 209s. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173958 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-30[analyzer] Model trivial copy/move ctors with an aggregate bind.Jordan Rose
This is faster for the analyzer to process than inlining the constructor and performing a member-wise copy, and it also solves the problem of warning when a partially-initialized POD struct is copied. Before: CGPoint p; p.x = 0; CGPoint p2 = p; <-- assigned value is garbage or undefined After: CGPoint p; p.x = 0; CGPoint p2 = p; // no-warning This matches our behavior in C, where we don't see a field-by-field copy. <rdar://problem/12305288> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173951 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-30Don't warn about Unicode characters in -E mode.Jordan Rose
People use the C preprocessor for things other than C files. Some of them have Unicode characters. We shouldn't warn about Unicode characters appearing outside of identifiers in this case. There's not currently a way for the preprocessor to tell if it's in -E mode, so I added a new flag, derived from the PreprocessorOutputOptions. This is only used by the Unicode warnings for now, but could conceivably be used by other warnings or even behavioral differences later. <rdar://problem/13107323> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173881 91177308-0d34-0410-b5e6-96231b3b80d8

If the member has an initializer, assume it was probably intended to be static and suggest/recover with that. If the member doesn't have an initializer, assume it was probably intended to be const instead of constexpr and suggest that. (if the attempt to apply these changes fails, don't make any suggestion & produce the same diagnostic experience as before. The only case where this can come up that I know of is with a mutable constexpr with an initializer, since mutable is incompatible with static (but it's already incompatible with const anyway)) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173873 91177308-0d34-0410-b5e6-96231b3b80d8
