* implement --debug-cc and --debug-link
* implement C source files having extra flags
- TODO a way to pass them on the CLI
* introduce the Directory abstraction which contains both an open file
descriptor and a file path name. The former is preferred but the
latter is needed when communicating paths over a command line (e.g.
to Clang or LLD).
* use the cache hash to choose an artifact directory
- TODO: use separate cache hash instances for the zig module and
each C object
* Module: introduce the crt_files table for keeping track of built libc
artifacts for linking.
* Add the ability to build 4/6 of the glibc static CRT lib files.
* The zig-cache directory is now passed as a parameter to Module.
* Implement the CLI logic of -femit-bin and -femit-h
- TODO: respect -fno-emit-bin
- TODO: the emit .h feature
* Add the -fvalgrind, -fstack-check, and --single-threaded CLI options.
* Implement the logic for auto detecting whether to enable PIC,
sanitize-C, stack-check, valgrind, and single-threaded.
* Properly add PIC args (or not) to clang argv.
* Implement renaming clang-compiled object files into their proper
place within the cache artifact directory.
- TODO: std lib needs a proper higher level abstraction for
std.os.renameat.
* Package is cleaned up to use the "Unmanaged" StringHashMap and use the
new Directory abstraction.
* Clean up zig lib directory detection to make proper use of directory
handles.
* Linker code invokes LLD.
- TODO properly deal with the stdout and stderr that we get from it
and expose diagnostics from the Module API that match the expected
error message format.
* Delete the bitrotted LLVM C ABI bindings. We'll resurrect just the
functions we need as we introduce dependencies on them. So far it
only has ZigLLDLink in it.
* Remove dead timer code.
* `zig env` now prints the path to the zig executable as well.
