Adjust documentation for git migration. This fixes most references to the paths: llvm.org/svn/ llvm.org/git/ llvm.org/viewvc/ github.com/llvm-mirror/ github.com/llvm-project/ reviews.llvm.org/diffusion/ to instead point to https://github.com/llvm/llvm-project. This is *not* a trivial substitution, because additionally, all the checkout instructions had to be migrated to instruct users on how to use the monorepo layout, setting LLVM_ENABLE_PROJECTS instead of checking out various projects into various subdirectories. I've attempted to not change any scripts here, only documentation. The scripts will have to be addressed separately. Additionally, I've deleted one document which appeared to be outdated and unneeded: lldb/docs/building-with-debug-llvm.txt Differential Revision: https://reviews.llvm.org/D57330 llvm-svn: 352514

Implement filesystem NB comments, relative paths, and related issues. This is a fairly large patch that implements all of the filesystem NB comments and the relative paths changes (ex. adding weakly_canonical). These issues and papers are all interrelated so their implementation couldn't be split up nicely. This patch upgrades <experimental/filesystem> to match the C++17 spec and not the published experimental TS spec. Some of the changes in this patch are both API and ABI breaking, however libc++ makes no guarantee about stability for experimental implementations. The major changes in this patch are: * Implement NB comments for filesystem (P0492R2), including: * Implement `perm_options` enum as part of NB comments, and update the `permissions` function to match. * Implement changes to `remove_filename` and `replace_filename` * Implement changes to `path::stem()` and `path::extension()` which support splitting examples like `.profile`. * Change path iteration to return an empty path instead of '.' for trailing separators. * Change `operator/=` to handle absolute paths on the RHS. * Change `absolute` to no longer accept a current path argument. * Implement relative paths according to NB comments (P0219r1) * Combine `path.cpp` and `operations.cpp` since some path functions require access to the operations internals, and some fs operations require access to the path parser. llvm-svn: 329028

[libc++] Implement Directory Entry Caching -- Sort of. Summary: This patch implements directory_entry caching *almost* as specified in P0317r1. However, I explicitly chose to deviate from the standard as I'll explain below. The approach I decided to take is a fully caching one. When `refresh()` is called, the cache is populated by calls to `stat` and `lstat` as needed. During directory iteration the cache is only populated with the `file_type` as reported by `readdir`. The cache can be in the following states: * `_Empty`: There is nothing in the cache (likely due to an error) * `_IterSymlink`: Created by directory iteration when we walk onto a symlink only the symlink file type is known. * `_IterNonSymlink`: Created by directory iteration when we walk onto a non-symlink. Both the regular file type and symlink file type are known. * `_RefreshSymlink` and `_RefreshNonSymlink`: A full cache created by `refresh()`. This case includes dead symlinks. * `_RefreshSymlinkUnresolved`: A partial cache created by refresh when we fail to resolve the file pointed to by a symlink (likely due to permissions). Symlink attributes are cached, but attributes about the linked entity are not. As mentioned, this implementation purposefully deviates from the standard. According to some readings of the specification, and the Windows filesystem implementation, the constructors and modifiers which don't pass an `error_code` must throw when the `directory_entry` points to a entity which doesn't exist. or when attribute resolution fails for another reason. @BillyONeal has proposed a more reasonable set of requirements, where modifiers other than refresh ignore errors. This is the behavior libc++ currently implements, with the expectation some form of the new language will be accepted into the standard. Some additional semantics which differ from the Windows implementation: 1. `refresh` will not throw when the entry doesn't exist. In this case we can still meet the functions specification, so we don't treat it as an error. 2. We don't clear the path name when a constructor fails via refresh (this will hopefully be changed in the standard as well). It should be noted that libstdc++'s current implementation has the same behavior as libc++, except for point (2). If the changes to the specification don't get accepted, we'll be able to make the changes later.

Implement P0430R2 - File system library on non-POSIX systems. This patch implements P0430R2, who's largest change is adding the path::format enumeration for supporting path format conversions in path constructors. However, since libc++'s filesystem only really supports POSIX like systems, there are no real changes needed. This patch simply adds the format enum and then ignores it when it's passed to constructors. llvm-svn: 329031

Implement filesystem NB comments, relative paths, and related issues. This is a fairly large patch that implements all of the filesystem NB comments and the relative paths changes (ex. adding weakly_canonical). These issues and papers are all interrelated so their implementation couldn't be split up nicely. This patch upgrades <experimental/filesystem> to match the C++17 spec and not the published experimental TS spec. Some of the changes in this patch are both API and ABI breaking, however libc++ makes no guarantee about stability for experimental implementations. The major changes in this patch are: * Implement NB comments for filesystem (P0492R2), including: * Implement `perm_options` enum as part of NB comments, and update the `permissions` function to match. * Implement changes to `remove_filename` and `replace_filename` * Implement changes to `path::stem()` and `path::extension()` which support splitting examples like `.profile`. * Change path iteration to return an empty path instead of '.' for trailing separators. * Change `operator/=` to handle absolute paths on the RHS. * Change `absolute` to no longer accept a current path argument. * Implement relative paths according to NB comments (P0219r1) * Combine `path.cpp` and `operations.cpp` since some path functions require access to the operations internals, and some fs operations require access to the path parser. llvm-svn: 329028

Fix implementation of ::abs and std::abs LWG 2192. Summary: All overloads of `::abs` and `std::abs` must be present in both `<cmath>` and `<cstdlib>`. This is problematic to implement because C defines `fabs` in `math.h` and `labs` in `stdlib.h`. This introduces a circular dependency between the two headers. This patch implements that requirement by moving `abs` into `math.h` and making `stdlib.h` include `math.h`. In order to get the underlying C declarations from the "real" `stdlib.h` inside our `math.h` we need some trickery. Specifically we need to make `stdlib.h` include next itself. Suggestions for a cleaner implementation are welcome.

[libc++] Take 2: Implement LWG 2510 Summary: LWG2510 makes tag types like allocator_arg_t explicitly default constructible instead of implicitly default constructible. It also makes the constructors for std::pair and std::tuple conditionally explicit based on the explicit-ness of the default constructibility for the pair/tuple's elements. This was previously committed as r372777 and reverted in r372832 due to the commit breaking LLVM's build in C++14 mode. This issue has now been addressed.

Implement <filesystem> This patch implements the <filesystem> header and uses that to provide <experimental/filesystem>. Unlike other standard headers, the symbols needed for <filesystem> have not yet been placed in libc++.so. Instead they live in the new libc++fs.a library. Users of filesystem are required to link this library. (Also note that libc++experimental no longer contains the definition of <experimental/filesystem>, which now requires linking libc++fs). The reason for keeping <filesystem> out of the dylib for now is that it's still somewhat experimental, and the possibility of requiring an ABI breaking change is very real. In the future the symbols will likely be moved into the dylib, or the dylib will be made to link libc++fs automagically). Note that moving the symbols out of libc++experimental may break user builds until they update to -lc++fs. This should be OK, because the experimental library provides no stability guarantees. However, I plan on looking into ways we can force libc++experimental to automagically link libc++fs. In order to use a single implementation and set of tests for <filesystem>, it has been placed in a special `__fs` namespace. This namespace is inline in C++17 onward, but not before that. As such implementation is available in C++11 onward, but no filesystem namespace is present "directly", and as such name conflicts shouldn't occur in C++11 or C++14. llvm-svn: 338093
