2013-03-16Remove -Wspellcheck and replace it with a diagnostic option.Argyrios Kyrtzidis
Thanks to Richard S. for pointing out that the warning would show up with -Weverything. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@177218 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-15[driver] Warnings for warning options are handled by the frontend. The ↵Chad Rosier
driver needs to process the warning options to setup diagnostic state, but should not be emitting warnings as these would be rudndant with what the frontend emits. rdar://13001556 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@172497 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
2012-10-23Use a .def file for most of the diagnostic options.Douglas Gregor
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@166520 91177308-0d34-0410-b5e6-96231b3b80d8
2012-10-23Make DiagnosticOptions intrusively reference-counted, and make sureDouglas Gregor
the various stakeholders bump up the reference count. In particular, the diagnostics engine now keeps the DiagnosticOptions object alive. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@166508 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
2012-05-16Tweek r156937 a bit so that the suggestions are correct.Chad Rosier

2012-05-16Warn about -Wno-foo where foo is an unknown warning option. This is helpful Chad Rosier
for subtle misspellings such as -Wno-unused-command-line-arguments instead of -Wno-unused-command-line-argument. Also fix the diagnostic messages to properly handle -Wno- options. Previously, the positive version was always emitted (i.e., -Wfoo was emitted for -Wno-foo). rdar://11461500 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@156937 91177308-0d34-0410-b5e6-96231b3b80d8

2012-01-27Due to a bug, -Wno-everything works like -Weverything. Fix the bug by havingArgyrios Kyrtzidis
-Wno-everything remap all warnings to ignored. We can now use "-Wno-everything -W<warning>" to ignore all warnings except specific ones. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@149121 91177308-0d34-0410-b5e6-96231b3b80d8

2011-12-16C++11 constexpr: Add note stacks containing backtraces if constant evaluationRichard Smith
fails within a call to a constexpr function. Add -fconstexpr-backtrace-limit argument to driver and frontend, to control the maximum number of notes so produced (default 10). Fix APValue printing to be able to pretty-print all APValue types, and move the testing for this functionality from a unittest to a -verify test now that it's visible in clang's output. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@146749 91177308-0d34-0410-b5e6-96231b3b80d8

2011-11-15Fix a regression from 143657. The second pass of the warning options should ↵Chad Rosier
only be emitting warnings/errors for unknown warning options. getDiagnosticsInGroup returns false if the diagnostics is found and true otherwise. Thus, if we're reporting and we have a valid diagnostic, we were actually setting the flag and causing mayhem. rdar://10444207 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@144670 91177308-0d34-0410-b5e6-96231b3b80d8
2011-11-15Warning option typo correction: When two options have the same edit_distance ↵Benjamin Kramer
don't display either. Also add a maximum edit distance threshold, so we don't correct "-Wx" to "-W#pragma-messages". git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@144644 91177308-0d34-0410-b5e6-96231b3b80d8
2011-11-14Print a typo correction hint for unknown warning flags.Benjamin Kramer
$ clang -Wololo t.c warning: unknown warning option '-Wololo'; did you mean '-Wall'? [-Wunknown-warning-option] git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@144591 91177308-0d34-0410-b5e6-96231b3b80d8
2011-11-03Parse the warning options twice. The first pass sets diagnostic state, while Chad Rosier
the second pass reports warnings/errors. This has the effect that we follow the more canonical "last option wins" paradigm when there are conflicting options. rdar://10383776 Previously, we parsed the warning options in order. This caused non-intuitive behavior: 1) clang test.c -Wnosuchwarning -Wno-unknown-warning-option Before: warning: unknown warning option '-Wnosuchwarning' [-Wunknown-warning-option] 1 warning generated. After: [0 warning generated.] 2) clang test.c -Wnosuchwarning -Werror=unknown-warning-option Before: warning: unknown warning option '-Wnosuchwarning' [-Wunknown-warning-option] 1 warning generated. After: error: unknown warning option '-Wnosuchwarning' [-Werror,-Wunknown-warning-option] 3) clang test.c -Werror=unknown-warning-option -Wnosuchwarning -Wno-error=unknown-warning-option -Wnosuchwarning Before: error: unknown warning option '-Wnosuchwarning' [-Werror,-Wunknown-warning-option] warning: unknown warning option '-Wnosuchwarning' [-Wunknown-warning-option] After: warning: unknown warning option '-Wnosuchwarning' [-Wunknown-warning-option] warning: unknown warning option '-Wnosuchwarning' [-Wunknown-warning-option] 2 warnings generated. 4) clang test.c -Werror=unknown-warning-option -Wnosuchwarning -Wno-error=unknown-warning-option -Wno-unknown-warning-option -Wnosuchwarning Before: error: unknown warning option '-Wnosuchwarning' [-Werror,-Wunknown-warning-option] After: [0 warning generated.] git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@143657 91177308-0d34-0410-b5e6-96231b3b80d8

2011-08-18Implement '-Weverything', which enables all warnings except those explicitly ↵Ted Kremenek
mapped to be ignored. Currently this includes -pedantic warnings as well; we'll need to consider whether these should be included. This works as expected with -Werror. Test cases were added to Sema/warn-unused-parameters.c, but they should probably be broken off into their own test file. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@137910 91177308-0d34-0410-b5e6-96231b3b80d8

Patch by Matthieu Monrocq with tweaks by me to avoid StringRefs in the static diagnostic data structures, which resulted in a huge global-var-init function. Depends on llvm commit r132046. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@132047 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-20Introduce a limit on the depth of the template instantiation backtraceDouglas Gregor
we will print with each error that occurs during template instantiation. When the backtrace is longer than that, we will print N/2 of the innermost backtrace entries and N/2 of the outermost backtrace entries, then skip the middle entries with a note such as: note: suppressed 2 template instantiation contexts; use -ftemplate-backtrace-limit=N to change the number of template instantiation entries shown This should eliminate some excessively long backtraces that aren't providing any value. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101882 91177308-0d34-0410-b5e6-96231b3b80d8
