* Parse: Move simple-type-specifier sanity check earlierDavid Majnemer2013-09-221-4/+5
| | | | | | No functional change, just makes the error handling a bit more obvious. llvm-svn: 191162
* Parse: Don't crash during parsing if we lack a simple-type-specifierDavid Majnemer2013-09-222-0/+6
| | | | | | | | | | | | | | | | | Summary: Parsing cast expressions during error recovery can put us in a bad state. Check to see if the token for a simple-type-specifier makes sense before further parsing. Fixes PR17255.

| | | | | | | | | | This solves the problem of fallback onto ourselves if clang-cl has been renamed to cl.exe and put on the PATH, as happens with the VS integration. Differential Revision: http://llvm-reviews.chandlerc.com/D1731 llvm-svn: 191099

* [analyzer] Use getParentIgnoreParenCasts instead of doing it by hand.Jordan Rose2013-09-201-3/+1
| | | | | | | | | | | | Apart from being more compact and already implemented, this also handles the case where the parent is null. (It does also ignore all casts, not just implicit ones, but this is more efficient to test and in the case we care about---a message in a PseudoObjectExpr---there should only be implicit casts anyway. This should fix our internal buildbot. llvm-svn: 191094
* [ASan] Do not imply -undefined dynamic_lookup when linking dylibs with ↵Alexander Potapenko2013-09-202-20/+4
| | | | | | | | | | -fsanitize=address. Instead add the ASan runtime to the linker command line so that only the ASan API functions can be undefined in the target library. Fixes http://llvm.org/bugs/show_bug.cgi?id=17275 llvm-svn: 191076
* Modify the uninitialized field visitor to detect uninitialized use across theRichard Trieu2013-09-201-32/+180
| | | | | | | | | | | | | | | | | | fields in the class. This allows a better checking of member intiailizers and in class initializers in regards to initialization ordering. For instance, this code will now produce warnings: class A { int x; int y; A() : x(y) {} // y is initialized after x, warn here A(int): y(x) {} // default initialization of leaves x uninitialized, warn here }; Several test cases were updated with -Wno-uninitialized to silence this warning. llvm-svn: 191068
* Switch the semantic DeclContext for a block-scope declaration of a function orRichard Smith2013-09-208-74/+211
| | | | | | | | | | | | | | variable from being the function to being the enclosing namespace scope (in C++) or the TU (in C). This allows us to fix a selection of related issues where we would build incorrect redeclaration chains for such declarations, and fail to notice type mismatches. Such declarations are put into a new IdentifierNamespace, IDNS_LocalExtern, which is only found when searching scopes, and not found when searching DeclContexts. Such a declaration is only made visible in its DeclContext if there are no non-LocalExtern declarations. llvm-svn: 191064

Also teach FixItUtils to look at whether the macro was defined at the source location for which it is creating a fixit, rather than looking at whether it's defined *now*. This is especially relevant for analysis-based warnings which are delayed until end of TU. llvm-svn: 191057
* Don't correct typos in Sema::BuildCXXNestedNameSpecifier with -fms-extensionsKaelyn Uhrain2013-09-191-1/+1
| | | | | | | | When -fms-extensions is enabled, the typo correction was being called here on non-error paths (as in test/SemaTemplate/lookup-dependent-bases.cpp) and correct compilation depended on Sema::CorrectTypo not finding a viable candidate. llvm-svn: 191046
* clang-cl: implement /fallback modeHans Wennborg2013-09-193-2/+136
| | | | | | | | | | | | | When this flag is enabled, clang-cl falls back to cl.exe if it cannot compile the code itself for some reason. The idea is to use this to help build projects that almost compile with clang-cl, except for some files that can then be built with the fallback mechanism.

* Make Preprocessor::Lex non-recursive.Eli Friedman2013-09-198-152/+248
| | | | | | | | | | | | | | | Before this patch, Lex() would recurse whenever the current lexer changed (e.g. upon entry into a macro). This patch turns the recursion into a loop: the various lex routines now don't return a token when the current lexer changes, and at the top level Preprocessor::Lex() now loops until it finds a token. Normally, the recursion wouldn't end up being very deep, but the recursion depth can explode in edge cases like a bunch of consecutive macros which expand to nothing (like in the testcase test/Preprocessor/macro_expand_empty.c in this patch). <rdar://problem/14569770> llvm-svn: 190980

* clang-cl: Don't warn about overriding /MD with /MT, /Fo with another /Fo, etc.Hans Wennborg2013-09-182-35/+1
| | | | | | | | | | | | | | | | I put in the warnings because MSVC has them, but I don't think they're very useful. Clang does not warn about overriding flags in general, e.g. it's perfectly fine to have -fomit-frame-pointer followed by -fno-omit-frame-pointer. We should focus on warning where things get confusing, such as with the /TP and /TC options. In "clang-cl /TC a.c /TP b.cc", the user might not realize that the /TP flag will apply to both files, and we warn about that.

| | | | | | | | | | | | | | | | | | | | | | | | | Fix for PR16752. Second commit. PR16752: 'mode' attribute for unusual targets doesn't work properly Description: Troubles could be happened due to some assumptions in handleModeAttr function (see SemaDeclAttr.cpp). For example, it assumes that 32 bit integer is 'int', while it could be 16 bit only. Instead of asking target: 'which type do you want to use for int32_t ?' it just hardcodes general opinion. That doesn't looks pretty correct. Please consider the next solution: 1. In Basic/TargetInfo add getIntTypeByWidth and getRealTypeByWidth methods. Methods asks target for proper type for given bit width. 2. Fix handleModeAttr according to new methods in TargetInfo. Fixes: 1st Commit (Done): Add new methods for TargetInfo: getRealTypeByWidth and getIntTypeByWidth for ASTContext names are almost same(invokes new methods from TargetInfo): getIntTypeForBitwidth and getRealTypeForBitwidth 2nd Commit (Current): Fix SemaDeclAttr, handleModeAttr function. Also test/Sema/attr-mode.c was fixed. 'XC' mode test was disabled for PPC64 machines. llvm-svn: 190926
* Add the intrinsic __builtin_convertvectorHal Finkel2013-09-1815-0/+217
| | | | | | | | | | | | | | | | | | LLVM supports applying conversion instructions to vectors of the same number of elements (fptrunc, fptosi, etc.) but there had been no way for a Clang user to cause such instructions to be generated when using builtin vector types. C-style casting on vectors is already defined in terms of bitcasts, and so cannot be used for these conversions as well (without leading to a very confusing set of semantics). As a result, this adds a __builtin_convertvector intrinsic (patterned after the OpenCL __builtin_astype intrinsic). This is intended to aid the creation of vector intrinsic headers that create generic IR instead of target-dependent intrinsics (in other words, this is a generic _mm_cvtepi32_ps). As noted in the documentation, the action of __builtin_convertvector is defined in terms of the action of a C-style cast on each vector element. llvm-svn: 190915
