* AST: flatten ControlFlowExpression into Continue, Break, and Return. * AST: unify identifiers and literals into the same AST type: OneToken * AST: ControlFlowExpression uses TrailerFlags to optimize storage space. * astgen: support `var` as well as `const` locals, and support explicitly typed locals. Corresponding Module and codegen code is not implemented yet. * astgen: support result locations. * ZIR: add the following instructions (see the corresponding doc comments for explanations of semantics): - alloc - alloc_inferred - bitcast_result_ptr - coerce_result_block_ptr - coerce_result_ptr - coerce_to_ptr_elem - ensure_result_used - ensure_result_non_error - ret_ptr - ret_type - store - param_type * the skeleton structure for result locations is set up. It's looking pretty clean so far. * add compile error for unused result and compile error for discarding errors. * astgen: split builtin calls up to implemented manually, and implement `@as`, `@bitCast` (and others) with respect to result locations. * add CLI support for hex and raw object formats. They are not supported by the self-hosted compiler yet, and emit errors. * rename `--c` CLI to `-ofmt=[objectformat]` which can be any of the object formats. Only ELF and C are supported so far. Also added missing help to the help text. * Remove hard tabs from C backend test cases. Shame on you Noam, you are grounded, you should know better, etc. Bad boy. * Delete C backend code and test case that relied on comptime_int incorrectly making it all the way to codegen.

Building from Source
Note that you can download a binary of master branch.
Stage 1: Build Zig from C++ Source Code
Dependencies
POSIX
- cmake >= 2.8.5
- gcc >= 5.0.0 or clang >= 3.6.0
- LLVM, Clang, LLD development libraries == 10.x, compiled with the same gcc or clang version above
- Use the system package manager, or build from source.
Windows
- cmake >= 3.15.3
- Microsoft Visual Studio. Supported versions:
- 2015 (version 14)
- 2017 (version 15.8)
- 2019 (version 16)
- LLVM, Clang, LLD development libraries == 10.x
- Use the pre-built binaries or build from source.
Instructions
POSIX
mkdir build
cd build
cmake ..
make install

MacOS
brew install cmake llvm
brew outdated llvm || brew upgrade llvm
mkdir build
cd build
cmake .. -DCMAKE_PREFIX_PATH=$(brew --prefix llvm)
make install
You will now run into this issue:
homebrew and llvm 10 packages in apt.llvm.org are broken with undefined reference to getPollyPluginInfo
or
error: unable to create target: 'Unable to find target for this triple (no targets are registered)',
in which case try -DZIG_WORKAROUND_4799=ON
Hopefully this will be fixed upstream with LLVM 10.0.1.
Windows
