This matches master branch. We can look into adding more target coverage
as we switch to stage2. As it stands, this works around having to
duplicate the "Executor" logic to figure out when to not run the tests
due to them being non-native.
* migrate runtime safety tests to the new test harness
- this required adding compare output / execution support for stage1
to the test harness.
* rename `zig build test-stage2` to `zig build test-cases` since it now
does quite a bit of stage1 testing actually. I named it this way
since the main directory in the source tree associated with these
tests is "test/cases/".
* add some documentation for the test manifest format.
Rename all references of sparcv9 to sparc64, to make Zig align more with
other projects. Also, added new function to convert glibc arch name to Zig
arch name, since it refers to the architecture as sparcv9.
This is based on the suggestion by @kubkon in PR 11847.
(https://github.com/ziglang/zig/pull/11487#pullrequestreview-963761757)
the list parameter should be a multi-item pointer rather than a single-item
pointer. see: https://linux.die.net/man/2/setgroups
> setgroups() sets the supplementary group IDs for the calling process...
> the size argument specifies the number of supplementary group IDs in the buffer pointed to by list.
The "slicing operator with sentinel" runtime safety test cases should
all have been compile errors in their current forms. In this commit I
adjust them to use runtime-known slices before triggering the runtime
safety.
Furthermore the test cases did not actually have unique names.
- Test: Fix bucket counting. Previously, the first hit was not counted.
This off-by-one error slightly increased the mean of `*_total_variance`,
which decreased the acceptance rate for a particular random seed
from 95% to 92.6%. (Irrelevant for test failure because the seed is fixed.)
- Improve comments
EnvMap provides the same API as the previously used BufMap (besides `putMove` and `getPtr`), so usage sites of `getEnvMap` can usually remain unchanged.
For non-Windows, EnvMap is a wrapper around BufMap. On Windows, it uses a new EnvMapWindows to handle some Windows-specific behavior:
- Lookups use Unicode-aware case insensitivity (but `get` cannot return an error because EnvMapWindows has an internal buffer to use for lookup conversions)
- Canonical names are returned when iterating the EnvMap
Fixes#10561, closes#4603
When handling the `negate` ZIR instruction, Zig now checks for a
comptime operand and handles it as a special case rather than lowering
it as `0 - x` so that the expression `-x` where `x` is a floating point
value known at compile-time, will get the negative zero bitwise
representation.
* back out the changes to RunStep
* move the disabled test to the .cpp code and avoid a confusing
name-collision with the _LIBCPP macro prefix
* fix merge conflict with the edits to the same test that ensure global
initializers are called.
Now this branch is only concerned with single-threaded targets and
passing the correct macro defines to libc++.

Since the plan is to ship stage3 for Zig 0.10.0, the stage1
implementation of this hardly matters.
* Rename std.builtin.GlobalVisibility to std.builtin.SymbolVisibility
* Add missing compile error. From the LLVM language reference: "A
symbol with internal or private linkage must have default
visibility."
