* Move generic isPrint and columnWidth implementations to a separate ↵Alexander Kornienko2013-09-043-105/+94
| | | | | | | | | | | | | | | | | | | | | header/source to allow using both generic and system-dependent versions on win32. Summary: This is needed so we can use generic columnWidthUTF8 in clang-format on win32 simultaneously with a separate system-dependent implementations of isPrint/columnWidth in TextDiagnostic.cpp to avoid attempts to print Unicode characters using narrow-character interfaces (which is not supported on Windows, and we'll have to figure out how to handle this).

* Change default # of digits for APFloat::toStringEli Friedman2013-08-291-4/+5
| | | | | | | | | | | | | | | | | This is a re-commit of r189442; I'll follow up with clang changes. The previous default was almost, but not quite enough digits to represent a floating-point value in a manner which preserves the representation when it's read back in. The larger default is much less confusing. I spent some time looking into printing exactly the right number of digits if a precision isn't specified, but it's kind of complicated, and I'm not really sure I understand what APFloat::toString is supposed to output for FormatPrecision != 0 (or maybe the current API specification is just silly, not sure which).

* Options: Add new option kind that consumes remaining argumentsHans Wennborg2013-08-132-0/+29
| | | | | | | | | | | | | | | | This adds KIND_REMAINING_ARGS, a class of options that consume all remaining arguments on the command line. This will be used to support /link in clang-cl, which is used to forward all remaining arguments to the linker. It also allows us to remove the hard-coded handling of "--", allowing clients (clang and lld) to implement that functionality themselves with this new option class.

* Introduce factory methods for SpecialCaseListAlexey Samsonov2013-08-121-2/+32
| | | | | | | | | | | | | | | | | | | | Summary: Doing work in constructors is bad: this change suggests to call SpecialCaseList::create(Path, Error) instead of "new SpecialCaseList(Path)". Currently the latter may crash with report_fatal_error, which is undesirable - sometimes we want to report the error to user gracefully - for example, if he provides an incorrect file as an argument of Clang's -fsanitize-blacklist flag.

After reading the Unicode Standard I came up with the code that uses definitions of "printable" and "column width" more suitable for terminal output (i.e. fixed-width fonts and special treatment of many control characters). The implementation here can probably be used for Windows and MacOS if someone can test it properly. The patch addresses PR14910.

| | | | | | | | | | | | | | | | | | This makes option aliases more powerful by enabling them to pass along arguments to the option they're aliasing. For example, if we have a joined option "-foo=", we can now specify a flag option "-bar" to be an alias of that, with the argument "baz". This is especially useful for the cl.exe compatible clang driver, where many options are aliases. For example, this patch enables us to alias "/Ox" to "-O3" (-O is a joined option), and "/WX" to "-Werror" (again, -W is a joined option).
