hadError (suppressing future diagnostics) if we didn't print an error. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72588 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-16PR3009: Get rid of bogus warning for scalar compound literals.Eli Friedman
This patch isn't quite ideal in that it eliminates the warning for constructs like "int a = {1};", where the braces are in fact redundant. However, that would have required a bunch of refactoring, and it's much less likely to cause confusion compared to redundant nested braces. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@71939 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-20Allow flexible array initializers that are not surrounded byDouglas Gregor
braces. We now build the appropriate fully-structured initializer list for such things. Per PR3618, verified that we're getting the right code generation. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@67353 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-04Implement semantic analysis for the GNU flexible array initializationDouglas Gregor
extension. The interaction with designated initializers is a bit... interesting... but we follow GNU's lead and don't permit too much crazy code in this area. Also, make the "excess initializers" error message a bit more informative.

2009-01-30Upgrade the "excess elements in array initializer" warning to anDouglas Gregor
error, since both C99 and C++ consider it an error. For reference, GCC makes this a warning while G++ makes it an error. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63435 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-28Code generation support for C99 designated initializers.Douglas Gregor
The approach I've taken in this patch is relatively straightforward, although the code itself is non-trivial. Essentially, as we process an initializer list we build up a fully-explicit representation of the initializer list, where each of the subobject initializations occurs in order. Designators serve to "fill in" subobject initializations in a non-linear way. The fully-explicit representation makes initializer lists (both with and without designators) easy to grok for codegen and later semantic analyses. We keep the syntactic form of the initializer list linked into the AST for those clients interested in exactly what the user wrote. Known limitations: - Designating a member of a union that isn't the first member may result in bogus initialization (we warn about this) - GNU array-range designators are not supported (we warn about this) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63242 91177308-0d34-0410-b5e6-96231b3b80d8

2008-02-11Fix PR1992 by computing the right type for string literals, whichChris Lattner
is an array type not a pointer type. This requires updating some diags that change and updating the code generator to handle the proper form of strings. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@46941 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-28Fix a bug with struct initializers (in Sema::CheckInitializerListTypes()). Steve Naroff
Test case included from bz1948 (thanks Neil!). Also fixed an 80 column violation... git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@46430 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-25Replace Sema::CheckVariableInitList, CheckConstantInitList, and ↵Steve Naroff
CheckForCharArrayInitializer with CheckInitializerListTypes. The new routine now supports struct/union initializers. This is a modified version of a patch by Eli Friedman. This version passes all of the clang tests and supports vectors:-) Note that Eli and I are still unsatisfied the implementation of CheckInitializerListTypes(). We'd like to find a more elegant implementation. Nevertheless, this is a complex part of the standard (and may be hard to simplify). Since the complexity is localized to this routine, we can iterate without too much disruption:-) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@46339 91177308-0d34-0410-b5e6-96231b3b80d8

2008-01-04Merge all the 'assignment' diagnostic code into one routine, decloning Chris Lattner
it from several places. This merges the diagnostics, making them more uniform and fewer in number. This also simplifies and cleans up the code. Some highlights: 1. This removes a bunch of very-similar diagnostics. 2. This renames AssignmentCheckResult -> AssignConvertType 3. This merges PointerFromInt + IntFromPointer which were always treated the same. 4. This updates a bunch of test cases that have minor changes to the produced diagnostics. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@45589 91177308-0d34-0410-b5e6-96231b3b80d8
2007-12-10Add support for initializing char arrays from string literals.Steve Naroff
Adapted from a patch by Anders Carlsson. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@44816 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-18Fix the following bug...Steve Naroff
unsigned char asso_values[] = { 34 }; int legal2() { return asso_values[0]; } The code that creates the new constant array type was operating on the original type. As a result, the constant type being generated was "unsigned char [1][]" (which is wrong). The fix is to operate on the element type - in this case, the correct type is "unsigned char [1]" I added this case to array-init.c, which clearly didn't catch this bogosity... git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@43112 91177308-0d34-0410-b5e6-96231b3b80d8

2007-09-26Removed option "-parse-ast-check" from clang driver. This is now implementedTed Kremenek
using "-parse-ast -verify". Updated all test cases (using a sed script) that invoked -parse-ast-check to now use -parse-ast -verify. Fixed a bug where using "-verify" instead of "-parse-ast-check" would not correctly create the DiagClient needed to accumulate diagnostics. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@42365 91177308-0d34-0410-b5e6-96231b3b80d8

2007-09-04More fun with initializers! Steve Naroff
- Fixed many bugs, enhanced test case considerably, added a diagnostic, etc. - Refactored CheckInitList() into CheckVariableInitList()/CheckConstantInitList(). - Added CheckInitExpr(). - Support for multi-dimensional arrays looking good. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@41690 91177308-0d34-0410-b5e6-96231b3b80d8

2007-09-02Start implementing semantic analysis for C initializers.Steve Naroff
Step 1: Start instantiating InitListExpr's. Step 2: Call newly added function Sema::CheckInitializer() from Sema::ParseDeclarator(). Step 3: Give InitListExpr's a preliminary type. Step 4: Start emitting diagnostics for simple assignments. Note: As a result of step 1, the CodeGen/mandel.c test asserts "Unimplemented agg expr!", which is expected. As a result of step 4, the test below now fails. This isn't expected and needs to be investigated (it appears type checking for C++ references is flawed in some way). ******************** TEST 'Sema/cxx-references.cpp' FAILED! ******************** Command: clang -fsyntax-only Sema/cxx-references.cpp Output: Sema/cxx-references.cpp:8:12: warning: incompatible pointer types assigning 'int &*' to 'int *' int *p = &r; ^~ Sema/cxx-references.cpp:10:20: error: incompatible types assigning 'int (int)' to 'int (&)(int)' int (&rg)(int) = g; ^ Sema/cxx-references.cpp:13:18: error: incompatible types assigning 'int [3]' to 'int (&)[3]' int (&ra)[3] = a; ^ Sema/cxx-references.cpp:16:14: error: incompatible types assigning 'int *' to 'int *&' int *& P = Q; ^ 4 diagnostics generated. ******************** TEST 'Sema/cxx-references.cpp' FAILED! ******************** git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@41671 91177308-0d34-0410-b5e6-96231b3b80d8
