Again, I tried to update cmake but it is untested. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@67605 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-22PTHManager::Create():Ted Kremenek
- Make the Diagnostic::Level for PTH errors to be specified by the caller clang (driver): - Set the PTHManager diagnostic level to "Diagnostic::Error" for -include-pth (a hard error) and Diagnostic::Warning for -token-cache (we can still proceed). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@67462 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-21Frontend: Handle empty input on stdin.Daniel Dunbar
- PR3854. I think it makes more sense to change MemoryBuffer::getSTDIN (return 0 should indicate error, not empty), but it is documented to return 0 for empty inputs, and some other code appears to rely on this. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@67449 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-20Implement "-include-pth" in low-level driver. This allows a PTH file to be usedTed Kremenek
similar to a regular file passed to "-include". When -include-pth is used, the low-level driver queries the PTH file for the name of the original source file that generated the PTH file and implicitly adds a '#include' for that file in the Predefines buffer. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@67352 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-19Per Daniel's suggestion, remove default case from switch statement to makeTed Kremenek
uncaught language cases a compile warning instead of a runtime error. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@67325 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-19Allow notes to be printed following a fatal error, then suppress anyDouglas Gregor
diagnostics following those notes. Make exceeding the template instantiation depth a fatal error. Thanks to Daniel for pointing out the problem! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@67320 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-16Build system changes to use TableGen to generate the variousDouglas Gregor
diagnostics. This builds on the patch that Sebastian committed and then revert. Major differences are: - We don't remove or use the current ".def" files. Instead, for now, we just make sure that we're building the ".inc" files. - Fixed CMake makefiles to run TableGen and build the ".inc" files when needed. Tested with both the Xcode and Makefile generators provided by CMake, so it should be solid. - Fixed normal makefiles to handle out-of-source builds that involve the ".inc" files. I'll send a separate patch to the list with Sebastian's changes that eliminate the use of the .def files. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@67058 91177308-0d34-0410-b5e6-96231b3b80d8

failing test case). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66991 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-13wire up a new -fno-builtin option, make it control things like simplifylibcalls,Chris Lattner
etc and make freestanding imply it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66972 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-13Implement template instantiation for several more kinds of expressions:Douglas Gregor
- C++ function casts, e.g., T(foo) - sizeof(), alignof() More importantly, this allows us to verify that we're performing overload resolution during template instantiation, with argument-dependent lookup and the "cached" results of name lookup from the template definition. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66947 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-13introduce a new -fheinous-gnu-extensions flag that enables reallyChris Lattner
really horrible extensions that are disabled by default but that can be accepted by -fheinous-gnu-extensions (but which always emit a warning when enabled). As our first instance of this, implement PR3788/PR3794, which allows non-lvalues in inline asms in contexts where lvalues are required. bleh. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66910 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-13implement a new -fprint-source-range-info option, whichChris Lattner
defaults to off. When enabled, it emits range info along with the file/line/col information for a diagnostic. This allows tools that textually parse the output of clang to know where the ranges are, even if they span multiple lines. For example, with: $ clang exprs.c -fprint-source-range-info We now produce: exprs.c:21:11:{21:12-21:13}: warning: use of unary operator that may be intended as compound assignment (+=) var =+ 5; // expected-warning {{use of unary operator that may be intended as compound assignment (+=)}} ^~ exprs.c:22:11:{22:12-22:13}: warning: use of unary operator that may be intended as compound assignment (-=) var =- 5; // expected-warning {{use of unary operator that may be intended as compound assignment (-=)}} ^~ exprs.c:36:13:{36:3-36:12}: error: assignment to cast is illegal, lvalue casts are not supported (float*)X = P; // expected-error {{assignment to cast is illegal, lvalue casts are not supported}} ~~~~~~~~~ ^ exprs.c:41:4:{41:3-41:4}: error: called object type 'int' is not a function or function pointer X(); // expected-error {{called object type 'int' is not a function or function pointer}} ~^ exprs.c:45:15:{45:8-45:14}{45:17-45:24}: error: invalid operands to binary expression ('int *' and '_Complex float') P = (P-42) + Gamma*4; // expected-error {{invalid operands to binary expression ('int *' and '_Complex float')}} ~~~~~~ ^ ~~~~~~~ exprs.c:61:7:{61:16-61:22}: error: invalid application of '__alignof' to bitfield R = __alignof(P->x); // expected-error {{invalid application of '__alignof' to bitfield}} expected-warning {{extension used}} ^ ~~~~~~ Note the range info after the column in the initial diagnostic. This is obviously really annoying if you're not a tool parsing the output of clang, which is why it is off by default. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66862 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-12API fix: All "bodies" for functions, Objective-C methods, blocks, are assumed toTed Kremenek
be CompoundStmts. I think this is a valid assumption, and felt that the API should reflect it. Others please validate this assumption to make sure I didn't break anything. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66814 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-12Add Diagnostic files for Frontend and move a couple errors over.Daniel Dunbar
- Notably, clang now exits with an error if it can't find a file. This flushed out a bug in the CGColorSpace.c test case. :) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66789 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-10Limit the template instantiation depth to some user-configurable valueDouglas Gregor
(default: 99). Beyond this limit, produce an error and consider the current template instantiation a failure. The stack we're building to track the instantiations will, eventually, be used to produce instantiation backtraces from diagnostics within template instantiation. However, we're not quite there yet. This adds a new Clang driver option -ftemplate-depth=NNN, which should eventually be generated from the GCC command-line operation -ftemplate-depth-NNN (note the '-' rather than the '='!). I did not make the driver changes to do this mapping. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66513 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-04Change Parser::ParseCaseStatement to use an iterative approach to parsingChris Lattner
multiple sequential case statements instead of doing it with recursion. This fixes a problem where we run out of stack space parsing 100K directly nested cases. There are a couple other problems that prevent this from being useful in practice (right now the example only parses correctly with -disable-free and doesn't work with -emit-llvm), but this is a start. I'm not including a testcase because it is large and uninteresting for regtesting. Sebastian, I would appreciate it if you could scrutinize the smart pointer gymnastics I do. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66011 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-03implement support for propagating *features* down to the code generatorChris Lattner
and defining target-specific macros based on them (like __SSE3__ and friends). After extensive discussion with Daniel, this work will need driver support, which will translate things like -msse3 into a -mattr feature. Until this work is done, the code in clang.cpp is disabled and the X86TargetInfo ctor still defaults to SSE2. With these two things changed, this code will work.
