Andrew Kelley d726c2a2d3 self-hosted: beginnings of stack allocation 
Comment out non-x86_64 architectures for now in codegen.zig, because
they all have compile errors for their codepaths anyway, and it was
bloating the compilation speed and memory usage when stage1 tried to
build self-hosted. Here's the panic message:

"Backend architectures that don't have good support yet are commented
out, to improve compilation performance. If you are interested in one
of these other backends feel free to uncomment them. Eventually these
will be completed, but stage1 is slow and a memory hog."

This is a workaround to lower the time it takes to build self-hosted
with stage1 as well as use less memory. It should fix the CI.

Additionally:
 * Add `single_mut_pointer` support to `Type`
 * Trivial implementation of stack allocation in codegen.zig. It does
   not deal with freeing yet, and it's missing the stack pointer
   adjustment prologue.
 * Add the `alloc` IR instruction and semantic analysis for `alloc` ZIR
   instruction.

Building from Source

Build Status

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
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

Instructions

POSIX
mkdir build
cd build
cmake ..
make install

Need help? Troubleshooting Build Issues

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brew outdated llvm || brew upgrade llvm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
