* Revert "Introduce a string_ostream string builder facilty"Alp Toker2014-06-26
| | | | | | Temporarily back out commits r211749, r211752 and r211754. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@211814 91177308-0d34-0410-b5e6-96231b3b80d8
* Introduce a string_ostream string builder faciltyAlp Toker2014-06-26
| | | | | | | | | | | | | | | | | | | | string_ostream is a safe and efficient string builder that combines opaque stack storage with a built-in ostream interface. small_string_ostream<bytes> additionally permits an explicit stack storage size other than the default 128 bytes to be provided. Beyond that, storage is transferred to the heap. This convenient class can be used in most places an std::string+raw_string_ostream pair or SmallString<>+raw_svector_ostream pair would previously have been used, in order to guarantee consistent access without byte truncation. The patch also converts much of LLVM to use the new facility. These changes include several probable bug fixes for truncated output, a programming error that's no longer possible with the new interface. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@211749 91177308-0d34-0410-b5e6-96231b3b80d8

* [Modules] Make Support/Debug.h modular. This requires it to not changeChandler Carruth2014-04-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | behavior based on other files defining DEBUG_TYPE, which means it cannot define DEBUG_TYPE at all. This is actually better IMO as it forces folks to define relevant DEBUG_TYPEs for their files. However, it requires all files that currently use DEBUG(...) to define a DEBUG_TYPE if they don't already. I've updated all such files in LLVM and will do the same for other upstream projects. This still leaves one important change in how LLVM uses the DEBUG_TYPE macro going forward: we need to only define the macro *after* header files have been #include-ed. Previously, this wasn't possible because Debug.h required the macro to be pre-defined. This commit removes that. By defining DEBUG_TYPE after the includes two things are fixed: - Header files that need to provide a DEBUG_TYPE for some inline code can do so by defining the macro before their inline code and undef-ing it afterward so the macro does not escape. - We no longer have rampant ODR violations due to including headers with different DEBUG_TYPE definitions. This may be mostly an academic violation today, but with modules these types of violations are easy to check for and potentially very relevant. Where necessary to suppor headers with DEBUG_TYPE, I have moved the definitions below the includes in this commit. I plan to move the rest of the DEBUG_TYPE macros in LLVM in subsequent commits; this one is big enough. The comments in Debug.h, which were hilariously out of date already, have been updated to reflect the recommended practice going forward. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@206822 91177308-0d34-0410-b5e6-96231b3b80d8

* Fix an invalid check for duplicate option categories.Alexander Kornienko2014-02-05
| | | | | | | | | | | | | | | | | | | | Summary: The check performed in the comparator is invalid, as some STL implementations enforce strict weak ordering by calling the comparator with the same value. This check was also in a wrong place: the assertion would only fire when -help was used. The new check is performed each time the category is registered (we are not going to have thousands of them, so it's fine to do it in O(N^2)).

* Better output for long help strings for command-line options.Alexander Kornienko2013-05-10
| | | | | | | | | | | | | | | | | | | | | Summary: This patch allows using \n inside long help strings for command-line options, so that all lines are equally indented. This is not a perfect solution, as we don't (and probably don't want to) know about terminal width, but it allows to format long help strings somehow readable without manually padding them with spaces. A motivating example is -help output from clang-format (source code in tools/clang-format/ClangFormat.cpp, see cl options offset, length, style, and dump-config).
