2020-02-10stage1: memory/report overhaulMichael Dusan
- split util_base.hpp from util.hpp - new namespaces: `mem` and `heap` - new `mem::Allocator` interface - new `heap::CAllocator` impl with global `heap::c_allocator` - new `heap::ArenaAllocator` impl - new `mem::TypeInfo` extracts names without RTTI - name extraction is enabled w/ ZIG_ENABLE_MEM_PROFILE=1 - new `mem::List` takes explicit `Allocator&` parameter - new `mem::HashMap` takes explicit `Allocator&` parameter - add Codegen.pass1_arena and use for all `ZigValue` allocs - deinit Codegen.pass1_arena early in `zig_llvm_emit_output()`

2020-02-06more std lib async I/O integrationAndrew Kelley
* `zig test` gainst `--test-evented-io` parameter and gains the ability to seamlessly run async tests. * `std.ChildProcess` opens its child process pipe with O_NONBLOCK when using evented I/O * `std.io.getStdErr()` gives a File that is blocking even in evented I/O mode. * Delete `std.event.fs`. The functionality is now merged into `std.fs` and async file system access (using a dedicated thread) is automatically handled. * `std.fs.File` can be configured to specify whether its handle is expected to block, and whether that is OK to block even when in async I/O mode. This makes async I/O work correctly for e.g. the file system as well as network. * `std.fs.File` has some deprecated functions removed. * Missing readv,writev,pread,pwrite,preadv,pwritev functions are added to `std.os` and `std.fs.File`. They are all integrated with async I/O. * `std.fs.Watch` is still bit rotted and needs to be audited in light of the new async/await syntax. * `std.io.OutStream` integrates with async I/O * linked list nodes in the std lib have default `null` values for `prev` and `next`. * Windows async I/O integration is enabled for reading/writing file handles. * Added `std.os.mode_t`. Integer sizes need to be audited. * Fixed #4403 which was causing compiler to crash. This is working towards: ./zig test ../test/stage1/behavior.zig --test-evented-io Which does not successfully build yet. I'd like to enable behavioral tests and std lib tests with --test-evented-io in the test matrix in the future, to prevent regressions.

This adds `--test-evented-io` as a CLI parameter. see #3117

2020-01-25split IrInstruction into IrInst, IrInstSrc, IrInstGenAndrew Kelley
This makes it so that less memory is used for IR instructions, as well as catching bugs when one expected one kind of instruction and received the other.

2020-01-22aarch64: less feature-full baseline CPUAndrew Kelley
2020-01-22fix not respecting sub-arch featureAndrew Kelley
2020-01-22std.Target.CpuFeatures is now a struct with both CPU and feature setAndrew Kelley
Previously it was a tagged union which was one of: * baseline * a specific CPU * a set of features Now, it's possible to have a CPU but also modify the CPU's feature set on top of that. This is closer to what LLVM does. This is more correct because Zig's notion of CPUs (and LLVM's) is not exact CPU models. For example "skylake" is not one very specific model; there are several different pieces of hardware that match "skylake" that have different feature sets enabled.

2020-01-16fix regressions double implicit casting return ptrAndrew Kelley
2020-01-16zig ir.cpp details: remove the mem_slot mechanismAndrew Kelley
Previously, there was hacky code to deal with result locations and how they work with regards to comptime values and runtime values. In addition, there was a hacky "mem_slot" mechanism that managed the memory for local variables, and acted differently depending on comptime vs runtime situations. All that is deleted in this commit, and as a result, result locations code has one less complication. Importantly, this means that a comptime result location is now passed to a function when it is evaluated at comptime. This test causes many regressions, and some of the behavior tests are disabled (commented out) in this commit. Future commits will re-enable the tests before merging the branch.
