* Implement -fshort-enums (rdar://8490496).Argyrios Kyrtzidis2010-10-081-0/+1
| | | | llvm-svn: 116020
* Introduce -flimit-debug-info.Devang Patel2010-09-301-0/+1
| | | | | | In this experimental mode try avoiding debug info emission for classes as much as possible. The goal is to reduce size of produced debuginfo without reducing quality of debug info in general. This is a work in progress. llvm-svn: 115188
* Added two new command line arguments:Marcin Swiderski2010-09-301-0/+2
| | | | | | | -cfg-add-implicit-dtors - sets CFG::BuildOptions::AddImplicitDtors for AnalysisCosumer to true, -cfg-add-initializers - sets CFG::BuildOptions::AddInitializers for AnalysisCosumer to true. llvm-svn: 115142
* Add a -ftrapv-handler= option which allows a handler to invoke instead of ↵David Chisnall2010-09-171-2/+11
| | | | | | simply aborting when a signed operation overflows. This mirrors the (GCC-incompatible) behaviour from clang 1.0 and 1.1 when -ftrapv was specified, but allows the handler to be defined for each compilation unit. llvm-svn: 114192
* Added AnalyzerStatsChecker, a path sensitive check that reports visitation ↵Tom Care2010-09-101-0/+3
| | | | | | statistics about analysis. Running clang with the -analyzer-stats flag will emit warnings containing the information. We can then run a postanalysis script to take this data and give useful information about how much the analyzer missed in a project. llvm-svn: 113568
* Frontend: Add -cxx-system-include option which can be used to specify anDaniel Dunbar2010-09-091-0/+6
| | | | | | | explicit list for the C++ system include directories at the -cc1 level, as an alternative to the horrible AddDefaultCPlusPlusIncludePaths(). llvm-svn: 113505
* Add support for Borland extensions via option -fborland-extensionsDawn Perchik2010-09-021-0/+3
| | | | | | (original patch r112791 was reverted due to a bug). llvm-svn: 112915
* Reverting rev 112791 - apparently -fborland-extensions is on all the time?!Dawn Perchik2010-09-021-3/+0
| | | | llvm-svn: 112797
* Add support for Borland extensions via option -fborland-extensionsDawn Perchik2010-09-021-0/+3
| | | | llvm-svn: 112791
* Straighten out target triples provided on the command lineDuncan Sands2010-08-301-1/+2
| | | | | | before using them. llvm-svn: 112468
* Frontend: Add basic -H support.Daniel Dunbar2010-08-241-2/+5
| | | | | | | - I didn't implement the GCC "multiple include guard" detection parts, because it doesn't seem useful or obvious. llvm-svn: 111983
* correct the -isystem option to not add the -isysroot path. Only the weirdChris Lattner2010-08-241-6/+7
| | | | | | -iwithsysroot flag should do that. This fixes rdar://8345942 llvm-svn: 111979
* Implement -iwithsysroot, an apple extension which is a close cousin of -isystem.Chris Lattner2010-08-241-1/+1
| | | | | | | Instead of implementing -isystem, I accidentally implemented this cousin. Next up is to implement -isystem right. llvm-svn: 111966
* Abstract out member-pointer creation. I'm really unhappy about the currentJohn McCall2010-08-221-6/+4
| | | | | | | | duplication between the constant and non-constant paths in all of this. Implement ARM ABI semantics for member pointer constants and conversion. llvm-svn: 111772
* Add machine-parseable Fix-It output as part of diagnostics, under theDouglas Gregor2010-08-191-0/+3
| | | | | | flag -fdiagnostics-parseable-fixits, from Eelis van der Weegen! llvm-svn: 111557
* Rename the ASTReader header files.Sebastian Redl2010-08-181-1/+1
| | | | llvm-svn: 111474
* Rename PCHReader to ASTReader.Sebastian Redl2010-08-181-1/+1
| | | | llvm-svn: 111467
* Reintroduce the serialization library, with fixed dependencies.Sebastian Redl2010-08-171-1/+1
| | | | llvm-svn: 111279
* Revert Sebastian's build-breaking patch.Douglas Gregor2010-08-171-1/+1
| | | | llvm-svn: 111265
* Create a new Serialization module that contains all the PCH code, and will ↵Sebastian Redl2010-08-171-1/+1
| | | | | | contain all the module code in the future. Update the Makefiles, CMake projects and the Xcode project. I hope I did everything right for Xcode. No functionality change. llvm-svn: 111258
* Add two options for playing with modules.Sebastian Redl2010-08-161-0/+8
| | | | llvm-svn: 111166
* Extend the code-completion caching infrastructure to include globalDouglas Gregor2010-08-151-0/+4
| | | | | | | | | | | | | | | | | | declarations (in addition to macros). Each kind of declaration maps to a certain set of completion contexts, and the ASTUnit completion logic introduces the completion strings for those declarations if the actual code-completion occurs in one of the contexts where it matters. There are a few new code-completion-context kinds. Without these, certain completions (e.g., after "using namespace") would need to suppress all global completions, which would be unfortunate. Note that we don't get the priorities right for global completions, because we don't have enough type information. We'll need a way to compare types in an ASTContext-agnostic way before this can be implemented. llvm-svn: 111093
* Add a new cc1 option -fix-what-you-can which when combined with the fix-it modeNick Lewycky2010-08-131-0/+3
| | | | | | will apply all fixes even when there were other errors in the file. llvm-svn: 111020
* Just disable the hidden-visibility optimization for now by hiding it behindJohn McCall2010-08-121-0/+1
| | | | | | | | a -cc1 option. The Darwin linker complains about mixed visibility when linking gcc-built objects with clang-built objects, and the optimization isn't really that valuable. Platforms with less ornery linkers can feel free to enable this. llvm-svn: 110979
* Frontend: Add -target-linker-version, for specifying the version string of theDaniel Dunbar2010-08-111-1/+6
| | | | | | linker in use. llvm-svn: 110871
* Make -funroll-loops turn on loop unrolling in the optimizer insteadEric Christopher2010-08-071-3/+7
| | | | | | of just ignoring it. llvm-svn: 110525
* Removed IdempotentOperationChecker from default analysis and returned back ↵Tom Care2010-08-061-0/+3
| | | | | | | | | to a flag (-analyzer-check-idempotent-operations) - Added IdempotentOperationChecker to experimental analyses for testing purposes - Updated test cases to explictly call the checker llvm-svn: 110482
* Add -cc1 option '-unoptimized-cfg' to toggle using a CFG (for static ↵Ted Kremenek2010-08-031-0/+1
| | | | | | analysis) that doesn't prune CFG edges. llvm-svn: 110087
* Implement -fno-validate-pch at the -cc1 level, which suppresses mostDouglas Gregor2010-07-271-1/+2
| | | | | | | | | | | | | | | of the usual consistency checks used to determine when a precompiled header is incompatible with the translation unit it's being loaded into. Enable this option when loading a precompiled preamble, because the preamble loader will be performing all of this checking itself. Enable the preamble-based test now that it's working. This option is also useful for debugging Clang's PCH (<rdar://problem/7532213>). llvm-svn: 109475
* Introduce basic support for loading a precompiled preamble whileDouglas Gregor2010-07-261-0/+17
| | | | | | | | | | | | | | | | | | | | | | | reparsing an ASTUnit. When saving a preamble, create a buffer larger than the actual file we're working with but fill everything from the end of the preamble to the end of the file with spaces (so the lexer will quickly skip them). When we load the file, create a buffer of the same size, filling it with the file and then spaces. Then, instruct the lexer to start lexing after the preamble, therefore continuing the parse from the spot where the preamble left off. It's now possible to perform a simple preamble build + parse (+ reparse) with ASTUnit. However, one has to disable a bunch of checking in the PCH reader to do so. That part isn't committed; it will likely be handled with some other kind of flag (e.g., -fno-validate-pch). As part of this, fix some issues with null termination of the memory buffers created for the preamble; we were trying to explicitly NULL-terminate them, even though they were also getting implicitly NULL terminated, leading to excess warnings about NULL characters in source files. llvm-svn: 109445
* Eliminate the "minimal" and printing parser actions, which only everDouglas Gregor2010-07-261-6/+0
| | | | | | | worked for C anyway. Also kills the -cc1 options -parse-noop and -parse-print-callbacks. llvm-svn: 109392
* Introduce a new lexer function to compute the "preamble" of a file,Douglas Gregor2010-07-201-0/+3
| | | | | | | | | which is the part of the file that contains all of the initial comments, includes, and preprocessor directives that occur before any of the actual code. Added a new -print-preamble cc1 action that is only used for testing. llvm-svn: 108913
* Improved false positive rate for the idempotent operations checker and moved ↵Tom Care2010-07-161-4/+0
| | | | | | | | | | it into the default path-sensitive analysis options. - Added checks for static local variables, self assigned parameters, and truncating/extending self assignments - Removed command line option (now default with --analyze) - Updated test cases to pass with idempotent operation warnings llvm-svn: 108550
* Introduce -f{no-}spell-checking options to enable/disableDouglas Gregor2010-07-091-0/+1
| | | | | | | spell-checking. By default, spell-checking is enabled for Clang (obviously) but disabled in CIndex for performance reasons. llvm-svn: 107992
* Add a frontend option -chained-pch and don't pass an active PCH reader to ↵Sebastian Redl2010-07-091-0/+3
| | | | | | the PCH writer if it is not set, preventing creation of chained PCH files. Since the reader is so far unused, effectively no functionality change. llvm-svn: 107936
* Added a path-sensitive idempotent operation checker ↵Tom Care2010-07-061-0/+4
| | | | | | | | | | | | | | | | | | | (-analyzer-idempotent-operation). Finds idempotent and/or tautological operations in a path sensitive context, flagging operations that have no effect or a predictable effect. Example: { int a = 1; int b = 5; int c = b / a; // a is 1 on all paths } - New IdempotentOperationChecker class - Moved recursive Stmt functions in r107675 to IdempotentOperationChecker - Minor refactoring of SVal to allow checking for any integer - Added command line option for check - Added basic test cases llvm-svn: 107706
* Driver/IRgen: Add support for -momit-leaf-frame-pointer.Daniel Dunbar2010-07-011-0/+3
| | | | llvm-svn: 107367
* Implement support for -fwrapv, rdar://7221421Chris Lattner2010-06-261-4/+10
| | | | | | | | | | | | As part of this, pull together trapv handling into the same enum. This also add support for NSW multiplies. This also makes PCH disagreement on overflow behavior silent, since it really doesn't matter except for warnings and codegen (no macros get defined etc). llvm-svn: 106956

* Driver: Fix arg_iterator typing to reflect that it is really an iterator ↵Daniel Dunbar2010-06-111-19/+22
| | | | | | over Arg*s. llvm-svn: 105838
* Add an option -fshow-overloads=best|all to limit the number of overloadJeffrey Yasskin2010-06-111-1/+12
| | | | | | | candidates printed. We default to 'all'. At the moment, 'best' prints only the first 4 overloads, but we'll improve that over time. llvm-svn: 105815
* Add an option to specify the target C++ ABI to the frontend. Use it toCharles Davis2010-06-111-0/+7

| | | | llvm-svn: 105759
* Frontend: Add FrontendAction support for handling LLVM IR inputs.Daniel Dunbar2010-06-071-1/+4
| | | | | | - These inputs follow an abbreviated execution path, but are still worth handling by FrontendAction so they reuse all the other clang -cc1 features. llvm-svn: 105582
* Frontend: Lift InputKind enumeration to top level.Daniel Dunbar2010-06-071-60/+58
| | | | llvm-svn: 105577
