| | | | | | | | | This can also be used instead of the WindowsSupport.h ConvertUTF8ToUTF16 helpers, but that will require massaging some character types. The Windows support routines want wchar_t output, but wchar_t is often 32 bits on non-Windows OSs. llvm-svn: 227122
* Teach raw_ostream to support hex formatting without a prefix '0x'.Zachary Turner2015-01-261-0/+2
| | | | | | | | | | Previously using format_hex() would always print a 0x prior to the hex characters. This allows this to be optional, so that one can choose to print (e.g.) 255 as either 0xFF or just FF. Differential Revision: http://reviews.llvm.org/D7151 llvm-svn: 227108
* Putting all the standard tool options into a "Generic" category.Chris Bieneman2015-01-261-0/+5
| | | | | | | | | | | | | | | Summary: This puts all the options that CommandLine.cpp implements into a category so that the APIs to hide options can not hide based on the generic category instead of string matching a partial list of argument strings. This patch is pretty simple and straight forward but it does impact the -help output of all tools using cl::opt. Specifically the options implemented in CommandLine.cpp (help, help-list, help-hidden, help-list-hidden, print-options, print-all-options, version) are all grouped together into an Option category, and these options are never hidden by the cl::HideUnrelatedOptions API.

* Support: Add *cast_or_null<> for pointer wrappersDuncan P. N. Exon Smith2014-11-241-0/+96
| | | | | | | | | | | | | | | | | | | | Fill in omission of `cast_or_null<>` and `dyn_cast_or_null<>` for types that wrap pointers (e.g., smart pointers). Type traits need to be slightly stricter than for `cast<>` and `dyn_cast<>` to resolve ambiguities with simple types. There didn't seem to be any unit tests for pointer wrappers, so I tested `isa<>`, `cast<>`, and `dyn_cast<>` while I was in there. This only supports pointer wrappers with a conversion to `bool` to check for null. If in the future it's useful to support wrappers without such a conversion, it should be a straightforward incremental step to use the `simplify_type` machinery for the null check. In that case, the unit tests should be updated to remove the `operator bool()` from the `pointer_wrappers::PTy`. llvm-svn: 222644

However, they were never documented, and later were replaced by "=init" category.

* Improve long path name support on Windows.Paul Robinson2014-11-131-2/+59
| | | | | | | | | | Windows normally limits the length of an absolute path name to 260 characters; directories can have lower limits. These limits increase to about 32K if you use absolute paths with the special '\\?\' prefix. Teach Support\Windows\Path.inc to use that prefix as needed. TODO: Other parts of Support could also learn to use this prefix. llvm-svn: 221841

* [Support] Add MemoryBuffer::getFileSlice()Nick Kledzik2014-10-081-0/+50
| | | | | | | | | | mach-o supports "fat" files which are a header/table-of-contents followed by a concatenation of mach-o files built for different architectures. Currently, MemoryBuffer has no easy way to map a subrange (slice) of a file which lld will need to select a mach-o slice of a fat file. The new function provides an easy way to map a slice of a file into a MemoryBuffer. Test case included. llvm-svn: 219260
* [Support] Add type-safe alternative to llvm::format()Nick Kledzik2014-09-251-0/+37
| | | | | | | | | | | | | | | | | | | | | llvm::format() is somewhat unsafe. The compiler does not check that integer parameter size matches the %x or %d size and it does not complain when a StringRef is passed for a %s. And correctly using a StringRef with format() is ugly because you have to convert it to a std::string then call c_str(). The cases where llvm::format() is useful is controlling how numbers and strings are printed, especially when you want fixed width output. This patch adds some new formatting functions to raw_streams to format numbers and StringRefs in a type safe manner. Some examples: OS << format_hex(255, 6) => "0x00ff" OS << format_hex(255, 4) => "0xff" OS << format_decimal(0, 5) => " 0" OS << format_decimal(255, 5) => " 255" OS << right_justify(Str, 5) => " foo" OS << left_justify(Str, 5) => "foo " llvm-svn: 218463
* LineIterator: Provide a variant that keeps blank linesJustin Bogner2014-09-171-9/+87

* Misc cleanups to the FileSytem api.Rafael Espindola2014-09-112-8/+7
| | | | | | | | | | | | | | | | The main difference is the removal of std::error_code exists(const Twine &path, bool &result); It was an horribly redundant interface since a file not existing is also a valid error_code. Now we have an access function that returns just an error_code. This is the only function that has to be implemented for Unix and Windows. The functions can_write, exists and can_execute an now just wrappers. One still has to be very careful using these function to avoid introducing race conditions (Time of check to time of use). llvm-svn: 217625

| | | | | | | | | | | | | Instead of aligning and moving the CurPtr forward, and then comparing with End, simply calculate how much space is needed, and compare that to how much is available. Hopefully this avoids any doubts about comparing addresses possibly derived from past the end of the slab array, overflowing, etc. Also add a test where aligning CurPtr would move it past End. llvm-svn: 217330
* Add writeFileWithSystemEncoding to LibLLVMSuppor.Rafael Espindola2014-09-031-0/+50
| | | | | | | | | | | | | | | | | | | | This patch adds to LLVMSupport the capability of writing files with international characters encoded in the current system encoding. This is relevant for Windows, where we can either use UTF16 or the current code page (the legacy Windows international characters). On UNIX, the file is always saved in UTF8. This will be used in a patch for clang to thoroughly support response files creation when calling other tools, addressing PR15171. On Windows, to correctly support internationalization, we need the ability to write response files both in UTF16 or the current code page, depending on the tool we will call. GCC for mingw, for instance, requires files to be encoded in the current code page. MSVC tools requires files to be encoded in UTF16. Patch by Rafael Auler! llvm-svn: 217068
* Ensure ErrorOr cannot implicitly invoke explicit ctors of the underlying type.David Blaikie2014-09-031-0/+31
| | | | | | | | | | | | | | | | | | | | | | | | An unpleasant surprise while migrating unique_ptrs (see changes in lib/Object): ErrorOr<int*> was implicitly convertible to ErrorOr<std::unique_ptr<int>>. Keep the explicit conversions otherwise it's a pain to convert ErrorOr<int*> to ErrorOr<std::unique_ptr<int>>. I'm not sure if there should be more SFINAE on those explicit ctors (I could check if !is_convertible && is_constructible, but since the ctor has to be called explicitly I don't think there's any need to disable them when !is_constructible - they'll just fail anyway. It's the converting ctors that can create interesting ambiguities without proper SFINAE). I had to SFINAE the explicit ones because otherwise they'd be ambiguous with the implicit ones in an explicit context, so far as I could tell. The converting assignment operators seemed unnecessary (and similarly buggy/dangerous) - just rely on the converting ctors to convert to the right type for assignment instead. llvm-svn: 217048

* Fix PR17239 by changing the semantics of the RemainingArgsClass Option kindReid Kleckner2014-08-221-3/+3
| | | | | | | | | | | | | | | | | | | | | | | This patch contains the LLVM side of the fix of PR17239. This bug that happens because the /link (clang-cl.exe argument) is marked as "consume all remaining arguments". However, when inside a response file, /link should only consume all remaining arguments inside the response file where it is located, not the entire command line after expansion. My patch will change the semantics of the RemainingArgsClass kind to always consume only until the end of the response file when the option originally came from a response file. There are only two options in this class: dash dash (--) and /link. Reviewed By: rnk Differential Revision: http://reviews.llvm.org/D4899 Patch by Rafael Auler! llvm-svn: 216280
