Andrew Kelley 93384f7428 use singly linked lists for std.zig.parse 
std.ast uses a singly linked list for lists of things. This is a
breaking change to the self-hosted parser API.

std.ast.Tree has been separated into a private "Parser" type which
represents in-progress parsing, and std.ast.Tree which has only
"output" data. This means cleaner, but breaking, API for parse results.
Specifically, `tokens` and `errors` are no longer SegmentedList but a
slice.

The way to iterate over AST nodes has necessarily changed since lists of
nodes are now singly linked lists rather than SegmentedList.

From these changes, I observe the following on the
self-hosted-parser benchmark from ziglang/gotta-go-fast:

throughput: 45.6 MiB/s => 55.6 MiB/s
maxrss: 359 KB => 342 KB

This commit breaks the build; more updates are necessary to fix API
usage of the self-hosted parser.

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
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brew outdated llvm || brew upgrade llvm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

Please help upstream LLVM and Homebrew solve this issue, there is nothing Zig can do about it. See that issue for a workaround you can do in the meantime.

Windows
