2013-04-23Make compares unsigned. The expression can't become negative anyways.Benjamin Kramer
Silences a sign compare warning on 32 bit archs. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@180110 91177308-0d34-0410-b5e6-96231b3b80d8
2013-03-15Fix buffer underrun (invalid read) triggered during diagnostic rendering. ↵Ted Kremenek
The test would overflow when computing '0 - 1'. I don't have a good testcase for this that does not depend on system headers. It did not trigger with preprocessed output, and I had trouble reducing the example. Fixes <rdar://problem/13324594>. Thanks to Michael Greiner for reporting this issue. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@177201 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-30Diagnostics: if a line is longer than 4096 characters, don't print it.Jordan Rose
Specifically, don't print snippets, caret diagnostics, or ranges for lines over 4096 characters. We copy the line around a few times in our diagnostics machinery, and we have to print a caret line that's just as long. This uses a lot of memory just to create a poor user experience as we print out a line much too long for anyone to read...or spend extra energy trying to fit it to -fmessage-length. <rdar://problem/13106850> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173976 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-04Sort all of Clang's files under 'lib', and fix up the broken headersChandler Carruth
uncovered. This required manually correcting all of the incorrect main-module headers I could find, and running the new llvm/utils/sort_includes.py script over the files. I also manually added quite a few missing headers that were uncovered by shuffling the order or moving headers up to be main-module-headers. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@169237 91177308-0d34-0410-b5e6-96231b3b80d8

2012-07-16Don't crash when emitting fixits following Unicode characters.Jordan Rose
This code is very sensitive to the difference between "columns" as printed and "bytes" (SourceManager columns). All variables are now named explicitly and our assumptions are (hopefully) documented as both comment and assertion. Whether parseable fixits should use byte offsets or Unicode character counts is pending discussion on the mailing list; currently the implementation uses bytes (and has no problems on lines containing multibyte characters). This has been added to the user manual. <rdar://problem/11877454> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@160319 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-26Add template type diffing to Clang. This feature will provide a betterRichard Trieu
comparison between two templated types when they both appear in a diagnostic. Type elision will remove indentical template arguments, which can be disabled with -fno-elide-type. Cyan highlighting is applied to the differing types. For more formatting, -fdiagnostic-show-template-tree will output the template type as an indented text tree, with differences appearing inline. Template tree works with or without type elision. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@159216 91177308-0d34-0410-b5e6-96231b3b80d8

2012-05-24fix Bug 12924Seth Cantrell
http://llvm.org/bugs/show_bug.cgi?id=12924 This issue was that the source location was pointing to a non-printable character and so CaretEnd was pointing one _column_ past the caret but not one _character_ past the caret. So the conversion between column and byte locations wasn't working (because the conversion is only valid from the first column or byte of a character). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@157372 91177308-0d34-0410-b5e6-96231b3b80d8
2012-05-10Fix an assertion hit when the serialized diagnostics writer receive a diagnosticArgyrios Kyrtzidis
from the frontend when the location is invalid and the SourceManager null. Instead of keeping the SourceManager object in DiagnosticRenderer, propagate it to the calls accordingly (as reference when it is expected to not be null, or pointer when it may be null). This effectively makes DiagnosticRenderer not tied to a specific SourceManager, removing a hack from TextDiagnosticPrinter. rdar://11386874 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@156536 91177308-0d34-0410-b5e6-96231b3b80d8
