- Combine mulXi3 routines for follow-up cleanup.
- DRY up Dwords and Twords
- rename both to HalveInt and use instance
* Justification: Not all processors have word size 32 bit.
* remove test file from CMakeLists
* DRY things.
And additionally support writing files to source files. This means a
custom build step in zig's own build.zig is no longer needed for copying
zig.h because it is handled by WriteFileStep.
Forcing the key to be of the same type as the sorted items used during
the search is a valid use case.
There, however, exists some cases where the key and the items are of
heterogeneous types, like searching for a code point in ordered ranges
of code points:
```zig
const CodePoint = u21;
const CodePointRange = [2]CodePoint;
const valid_ranges = &[_]CodePointRange{
// an ordered array of ranges
};
fn orderCodePointAndRange(
context: void,
code_point: CodePoint,
range: CodePointRange
) std.math.Order {
_ = context;
if (code_point < range[0]) {
return .lt;
}
if (code_point > range[1]) {
return .gt;
}
return .eq;
}
fn isValidCodePoint(code_point: CodePoint) bool {
return std.sort.binarySearch(
CodePointRange,
code_point,
valid_ranges,
void,
orderCodePointAndRange
) != null;
}
```
It is so expected that `std.sort.binarySearch` should therefore support
both homogeneous and heterogeneous keys.
This requires manual defines before C99 which may not have stdint.h.
Also have update-zig1 leave a copy of lib/zig.h in stage1/zig.h, which
allows lib/zig.h to be updated without needing to update zig1.wasm.
Note that since the object already existed with the exact same contents,
this completely avoids repo bloat due to zig.h changes.
- Fix assertion failure if AstGen failed on a multi-module file
- Cap number of per-error reference notes and total multi-module errors each at 5
- Always put "root of package" reference notes first
Resolves: #14499
lld accepts both syntaxes, but we were rejecting (and, before
3f7e9ff597a3514bb1c4f1900027c40682ac9f13, ignoring) the former.
In particular, "cargo-zigbuild" was broken since Rust
unconditionally adds "-znoexecstack" (not "-z noexecstack")
on non-Windows platforms.
