* Add new debug kind LocTrackingOnly.Diego Novillo2014-06-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This new debug emission kind supports emitting line location information in all instructions, but stops code generation from emitting debug info to the final output. This mode is useful when the backend wants to track source locations during code generation, but it does not want to produce debug info. This is currently used by optimization remarks (-Rpass, -Rpass-missed and -Rpass-analysis). When one of the -Rpass flags is used, the front end will enable location tracking, only if no other debug option is enabled. To prevent debug information from being generated, a new debug info kind LocTrackingOnly causes DIBuilder::createCompileUnit() to not emit the llvm.dbg.cu annotation. This blocks final code generation from generating debug info in the back end. Depends on D4234.

* Remove top-level Clang -fsanitize= flags for optional ASan features.Alexey Samsonov2014-06-13
| | | | | | | | | | | | | | Init-order and use-after-return modes can currently be enabled by runtime flags. use-after-scope mode is not really working at the moment. The only problem I see is that users won't be able to disable extra instrumentation for init-order and use-after-scope by a top-level Clang flag. But this instrumentation was implicitly enabled for quite a while and we didn't hear from users hurt by it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@210924 91177308-0d34-0410-b5e6-96231b3b80d8

Renamed the options to --system-header-prefix=/--no-system-header-prefix to avoid interference with -isystem and make the intent of the option cleaner.

* Add 'remark' diagnostic type in 'clang'Tobias Grosser2014-02-28
| | | | | | | | | | | | | | | | | | | | | | | A 'remark' is information that is not an error or a warning, but rather some additional information provided to the user. In contrast to a 'note' a 'remark' is an independent diagnostic, whereas a 'note' always depends on another diagnostic. A typical use case for remark nodes is information provided to the user, e.g. information provided by the vectorizer about loops that have been vectorized. This patch provides the initial implementation of 'remarks'. It includes the actual definiton of the remark nodes, their printing as well as basic parameter handling. We are reusing the existing diagnostic parameters which means a remark can be enabled with normal '-Wdiagnostic-name' flags and can be upgraded to an error using '-Werror=diagnostic-name'. '-Werror' alone does not upgrade remarks. This patch is by intention minimal in terms of parameter handling. More experience and more discussions will most likely lead to further enhancements in the parameter handling. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@202475 91177308-0d34-0410-b5e6-96231b3b80d8

* Add -fansi-escape-codes optionNico Rieck2013-09-11
| | | | | | | | | | | | | Some build systems use pipes for stdin/stderr. On nix-ish platforms colored output can be forced by -fcolor-diagnostics. On Windows this option has no effect in these cases because LLVM uses the console API (which only operates on the console buffer) even if a console wrapper capable of interpreting ANSI escape codes is used. The -fansi-escape-codes option allows switching from the console API to ANSI escape codes. It has no effect on other platforms. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@190464 91177308-0d34-0410-b5e6-96231b3b80d8
