* Parse the warning options twice. The first pass sets diagnostic state, while Chad Rosier2011-11-031-70/+92
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.] llvm-svn: 143657
* Basic/Diagnostic: Factor outDaniel Dunbar2011-09-291-14/+22
| | | | | | | | | DiagnosticsEngine::setDiagnosticGroup{ErrorAsFatal,WarningAsError} methods which more accurately model the correct API -- no internal change to the diagnostics engine yet though. - Also, stop honoring -Werror=everything (etc.) as a valid (but oddly behaved) option. llvm-svn: 140747
* Rename Diagnostic to DiagnosticsEngine as per issue 5397David Blaikie2011-09-251-5/+5

* Implement '-Weverything', which enables all warnings except those explicitly ↵Ted Kremenek2011-08-181-0/+7
| | | | | | | | | | | | | | 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. llvm-svn: 137910
* remove unneeded llvm:: namespace qualifiers on some core types now that ↵Chris Lattner2011-07-231-3/+3
| | | | | | | | LLVM.h imports them into the clang namespace. llvm-svn: 135852
* Don't warn about -Wno-foo where foo is an unknown warning option. ExplicitlyMatt Beaumont-Gay2011-06-031-1/+3
| | | | | | passing -Wunknown-warning-option will re-enable warnings about -Wno-foo. llvm-svn: 132570
* A StringRef-ication of the DiagnosticIDs API and internals.Argyrios Kyrtzidis2011-05-251-27/+22
| | | | | | | | | 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. llvm-svn: 132047
* Add an option -fshow-overloads=best|all to limit the number of overloadJeffrey Yasskin2010-06-111-0/+2
| | | | | | | candidates printed. We default to 'all'. At the moment, 'best' prints only the first 4 overloads, but we'll improve that over time. llvm-svn: 105815
* Introduce a limit on the depth of the template instantiation backtraceDouglas Gregor2010-04-201-0/+2
| | | | | | | | | | | | | | | | 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. llvm-svn: 101882
* add clang -cc1 level support for "-ferror-limit 42"Chris Lattner2010-04-071-0/+4

* switch -Werror/-Wfatal-errors error conditions to use diagnostics insteadChris Lattner2009-12-231-9/+7

* PR4715Shantonu Sen2009-08-141-1/+1
| | | | | | | -Wno-error disables WarningsAsErrors instead of mistakenly being treated like -Werror llvm-svn: 78987
* switch Warnings.cpp to use the diagnostics machinery to print diagnostics, ↵Chris Lattner2009-06-231-1/+3
| | | | | | | | | | | | | | not *fprintf*! Among other things, this makes the warning about unknown warning options mappable. For example: $ clang t.c -Werror -Wfoo error: unknown warning option '-Wfoo' [-Wunknown-warning-option] For another thing, they are properly color coded now too :) llvm-svn: 73936
* Clean up some unnecessary includes.Eli Friedman2009-05-191-1/+1
