2013-02-08Simplify logic for avoiding concatenation after numeric constants.Jordan Rose
I threw in a couple of test cases for UD-suffixes -- already working, but it wasn't immediately obvious to me. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174767 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-08StmtPrinter: Write large char values using \u or \U.Jordan Rose
This may not always be valid, but we were previously just emitting them raw. While here, s/isprint/isPrintable/ (using the new CharInfo). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174766 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-08Pull Lexer's CharInfo table out for general use throughout Clang.Jordan Rose
Rewriting the same predicates over and over again is bad for code size and code maintainence. Using the functions in <ctype.h> is generally unsafe unless they are specified to be locale-independent (i.e. only isdigit and isxdigit). The next commit will try to clean up uses of <ctype.h> functions within Clang. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174765 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-08Fix handling of fake parenthesis during formatting.Daniel Jasper
They are much easier to handle when attached to the previous token. Before: unsigned Indent = formatFirstToken(TheLine.First, IndentForLevel[TheLine.Level] >= 0 ? IndentForLevel[TheLine.Level] : TheLine.Level * 2, TheLine.InPPDirective, PreviousEndOfLineColumn); After: unsigned Indent = formatFirstToken( TheLine.First, IndentForLevel[TheLine.Level] >= 0 ?

2013-02-08Implement a tiny expression parser to improve formatting decisions.Daniel Jasper
With this patch, the formatter introduces 'fake' parenthesis according to the operator precedence of binary operators. Before: return aaaa & AAAAAAAAAAAAAAAAAAAAAAAAAAAAA || bbbb & BBBBBBBBBBBBBBBBBBBBBBBBBBBBB || cccc & CCCCCCCCCCCCCCCCCCCCCCCCCC || dddd & DDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDD; f(aaaaaaaaaaaaaaaaaaaa && aaaaaaaaaaaaaaaaaaaa, aaaaaaaaaaaaaaaaaaaa && aaaaaaaaaaaaaaaaaaaa, aaaaaaaaaaaaaaaaaaaa && aaaaaaaaaaaaaaaaaaaa); After: return aaaa & AAAAAAAAAAAAAAAAAAAAAAAAAAAAA || bbbb & BBBBBBBBBBBBBBBBBBBBBBBBBBBBB || cccc & CCCCCCCCCCCCCCCCCCCCCCCCCC || dddd & DDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDD; f(aaaaaaaaaaaaaaaaaaaa && aaaaaaaaaaaaaaaaaaaa, aaaaaaaaaaaaaaaaaaaa && aaaaaaaaaaaaaaaaaaaa, aaaaaaaaaaaaaaaaaaaa && aaaaaaaaaaaaaaaaaaaa); Future improvements: - Get rid of some of the hacky ways to nicely format certain constructs. - Merge this parser and the AnnotatingParser as we now have several parsers that analyze (), [], etc. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174714 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-08Improve filechecking of volatile test.Tim Northover
My previous attempt was extremely deficient, allowing more volatiles to be introduced and not even checking all of the ones that are present. This attempt doesn't try to keep track of the values stored or offsets within particular objects, just that the correct objects are accessed in a correctly volatile manner throughout. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174700 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-08CMake: Include Clang unit tests in check-clang target in standalone builds.Jordan Rose
Also, remove CLANG_BUILD_TESTS option. It won't have consistent behavior between standalone and non-standalone builds, so I'm not going to bother hooking it up for standalone builds. LLVM_BUILD_TESTS will continue to control unit test inclusion in the "all" target in non-standalone builds. Finally, fix the default value of CLANG_INCLUDE_TESTS, which was being set to the boolean value of "LLVM_INCLUDE_TESTS", i.e. OFF, rather than actually reading the variable ${LLVM_INCLUDE_TESTS}! If you picked up my earlier commit, YOU WILL HAVE TO MANUALLY SET THIS OPTION BACK ON. My apologies! Part two of r174691 (allow the unit tests to be built in standalone mode). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174698 91177308-0d34-0410-b5e6-96231b3b80d8

included in the same test. Clang gets confused about whether it's already built a module for this file, when running on a content-addressible filesystem. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174694 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-08CMake: Optionally allow running the Clang unit tests in standalone builds.Jordan Rose
The reason this is not enabled by default is because there is no way for Clang to guarantee that the LLVM unit testing infrastruture has been built. However, if it /has/ been built, there's no reason why the standalone Clang build can't use it! This should have no effect on existing builds -- in a combined build the value of the CLANG_INCLUDE_TESTS option defaults to the LLVM equivalent, and in a standalone build it defaults to off. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174691 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-08Fix stack overflow and improve performance when a module contains manyRichard Smith
overloads of a name by claiming that there are no lookup results for that name in modules while loading the names from the module. Lookups in deserialization really don't want to find names which they themselves are in the process of introducing. This also has the pleasant side-effect of automatically caching PCH lookups which found no names. The runtime here is still quadratic in the number of overloads, but the constant is lower. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174685 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-07[analyzer] Report bugs when freeing memory with offset pointerAnna Zaks
The malloc checker will now catch the case when a previously malloc'ed region is freed, but the pointer passed to free does not point to the start of the allocated memory. For example: int *p1 = malloc(sizeof(int)); p1++; free(p1); // warn From the "memory.LeakPtrValChanged enhancement to unix.Malloc" entry in the list of potential checkers. A patch by Branden Archer! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174678 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-07[analyzer] Add pointer escape type param to checkPointerEscape callbackAnna Zaks
The checkPointerEscape callback previously did not specify how a pointer escaped. This change includes an enum which describes the different ways a pointer may escape. This enum is passed to the checkPointerEscape callback when a pointer escapes. If the escape is due to a function call, the call is passed. This changes previous behavior where the call is passed as NULL if the escape was due to indirectly invalidating the region the pointer referenced. A patch by Branden Archer! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174677 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-07[analyzer] Don't reinitialize static globals more than once along a pathAnna Zaks
This patch makes sure that we do not reinitialize static globals when the function is called more than once along a path. The motivation is code with initialization patterns that rely on 2 static variables, where one of them has an initializer while the other does not. Currently, we reset the static variables with initializers on every visit to the function along a path. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174676 91177308-0d34-0410-b5e6-96231b3b80d8
