2009-05-15Template instantiation for "if" statements. Also:Douglas Gregor
- Skip semantic analysis of the "if" condition if it is type-dependent. - Added the location of the "else" keyword into IfStmt, so that we can provide it for type-checking after template instantiation. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@71875 91177308-0d34-0410-b5e6-96231b3b80d8

2009-05-14Link FunctionDecls instantiated from the member functions of a classDouglas Gregor
template to the FunctionDecls from which they were instantiated. This is a necessary first step to support instantiation of the definitions of such functions, but by itself does essentially nothing. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@71792 91177308-0d34-0410-b5e6-96231b3b80d8

2009-05-05Fix rdar://6849429 - -Wunused-value with deeply nested macro expansion ↵Chris Lattner
generates untraceable warnings The "instantiated from" messages coming from the caret diagnostics system are basically walking the macro expansion tree, emitting each level as it goes. However, it was skipping certain leaves in the tree by skipping up the entire instantiation arm every time it went up one spelling arm. This caused it to miss some things. For example, in this testcase: #define M1(x) x #define M2 1; void foo() { M1(M2) } we now print: /Users/sabre/Desktop/clang-unused-value-macro.c:6:2: warning: expression result unused M1(M2) ^~~~~~ /Users/sabre/Desktop/clang-unused-value-macro.c:6:5: note: instantiated from: M1(M2) ^~ /Users/sabre/Desktop/clang-unused-value-macro.c:3:12: note: instantiated from: #define M2 1; ^ Previously we didn't print the last line, so we never emitted the caret pointing to the 1! Incidentally, the spaces between the lines is really noisy, I think we should reconsider this heuristic (which adds them when the printed code starts too close to the start of the line). The regression test can't use -verify, because -verify doesn't catch notes for macro instantiation history. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@71025 91177308-0d34-0410-b5e6-96231b3b80d8

2009-05-04Rename attributes:Ted Kremenek
'objc_ownership_cfretain' -> 'cf_ownership_retain' 'objc_ownership_cfrelease' -> 'cf_ownership_release' Motivation: Core Foundation objects can be used in isolation from Objective-C, and this forces users to reason about the separate semantics of CF objects. More Sema support pending. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70884 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-04Simplify the interesting-region code by assimmilating blocks of ↵Douglas Gregor
non-whitespace text with each expansion step. It's easier and seems to have better results. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70833 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-04Tweak the extraction of the "interesting" part of a source range in two ways: Douglas Gregor
1) First of all, we treat _ as part of an identifier and not as punctuation (oops). 2) Second of all, always make sure that the token that the ^ is pointing at is fully within the "interesting" part of the range. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70831 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-03Fix an infinite loop in diagnostic printing.Daniel Dunbar
- The diagnostic is still poor, however. Doug, can you investigate? - Improved the test case to not depend on the file name, now it can be extended to actually check the formatting of the diagnostics (I'm hoping grep -A is portable here). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70807 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-03Fix crash in source-line truncation code for diagnosticDouglas Gregor
printing. Also, when we only need to truncate the line at the end, make sure there is room for the ellipsis. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70781 91177308-0d34-0410-b5e6-96231b3b80d8

2009-05-03When a fix-it hint would span multiple lines, don't print it; half aDouglas Gregor
fix-it hint is much worse than no fix-it hint. (Fixes PR4084). When we need to truncate a source line to fix in the terminal, make sure to take the width of the fix-it information into account, too. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70656 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-03When we truncate a source line to fit it within the terminal width,Douglas Gregor
show an ellipsis where we have removed text. An example: /Users/dgregor/Projects/llvm/tools/clang/test/Misc/message-length.c:18:120: warning: comparison of distinct pointer types ('int *' and 'float *') ...a_func_to_call(ip == FloatPointer, ip[ALongIndexName], ... ~~ ^ ~~~~~~~~~~~~ git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70655 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-03Respect the COLUMNS environment variable for word-wrapping (so we getDouglas Gregor
word-wrapping by default in Emacs; yay!). Thanks, Daniel. Use LLVM's System layer rather than calling isatty() directly. Fix a thinko in printing the indentation string that was causing some weird output. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70654 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-01When printing a source line as part of a diagnostic, the source lineDouglas Gregor
might be wider than we're supposed to print. In this case, we try to select the "important" subregion of the source line, which contains everything that we want to show (e.g., with underlining and the caret itself) and tries to also contain some of the context. From the fantastically long line in the test case, we get an error message that slices down to this: message-length.c:18:120: warning: comparison of distinct pointer types ('int *' and 'float *') a_func_to_call(ip == FloatPointer, ip[ALongIndexName], ~~ ^ ~~~~~~~~~~~~ There are a bunch of gee-it-sounds-good heuristics in here, which seem to do well on the various simple tests I've thrown at it. However, we're going to need to look at a bunch more diagnostics to tweak these heuristics. This is the second part of <rdar://problem/6711348>. Almost there! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70597 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-01Implement -fmessage-length=N, which word-wraps diagnostics to N columns. Douglas Gregor
Also, put a line of whitespace between the diagnostic and the source code/caret line when the start of the actual source code text lines up (or nearly lines up) with the most recent line of the diagnostic. For example, here it's okay for the last line of the diagnostic to be (vertically) next to the source line, because there is horizontal whitespace to separate them: decl-expr-ambiguity.cpp:12:16: error: function-style cast to a builtin type can only take one argument typeof(int)(a,5)<<a; However, here is a case where we need the vertical separation (since there is no horizontal separation): message-length.c:10:46: warning: incompatible pointer types initializing 'void (int, float, char, float)', expected 'int (*)(int, float, short, float)' int (*fp1)(int, float, short, float) = f; This is part one of <rdar://problem/6711348>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70578 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-30initial support for __[u]int128_t, which should be basicallyChris Lattner
compatible with VC++ and GCC. The codegen/mangling angle hasn't been fully ironed out yet. Note that we accept int128_t even in 32-bit mode, unlike gcc. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70464 91177308-0d34-0410-b5e6-96231b3b80d8

- Add an (optional) short description for BugReports for clients that want to distinguish between long and short descriptions for bugs - Make the bug report for VLA less obscene for Plist diagnostics by using the short description git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70415 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-28In -fdiagnostics-print-source-range-info mode, print a space before theChris Lattner

2009-04-28Implement ownership attribute 'objc_ownership_make_collectable'. This allows oneTed Kremenek
to add 'CFMakeCollectable' semantics to a method. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70336 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-28Optimize IdentifierInfo storage within the precompiled header. We'veDouglas Gregor

2009-04-28Implement a minor space optimization for the PCH identifier table,Douglas Gregor
which eliminates the storage for IdentifierInfo in the "uninteresting identifier" cases. Sadly, this only brought back 7k of the 500k we lost :( git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70325 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-28Implement checking for macro definitions that occur on the commandDouglas Gregor
line when using a PCH that were not provided when building the PCH file. If those names were used as identifiers somewhere in the PCH file, reject the PCH file. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70321 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-28Revert r70075 and r70078, which reorganized the PCH on-disk hash tableDouglas Gregor
for identifiers to separate "interesting" from "uninteresting" identifiers. However, to cope with compiler invocations where the predefines buffers mismatch, we need to be able to search the complete identifier table. Cocoa.h.pch is now about 500k larger that it used to be :( git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70320 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-28Allow some differences between the predefines buffer used to build aDouglas Gregor
PCH file and the predefines buffer used when including the PCH file. We (explicitly) detect conflicting macro definitions (rejecting the PCH file) and about missing macro definitions (they'll be automatically pulled from the PCH file anyway). We're missing some checking to make sure that new macro definitions won't have any impact on the PCH file itself (e.g., #define'ing an identifier that the PCH file used). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70316 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-27Add a header containing the Clang version; make the driver use thisDouglas Gregor
Clang version value rather than hard-coding "1.0". Add PCH and Clang version information into the PCH file. Reject PCH files with the wrong version information. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70264 91177308-0d34-0410-b5e6-96231b3b80d8
