An attempt to normalize some of the function names in build.zig. Normalize add*Dir to add*Path. Also use "Library" instead of the "Lib" abbreviation.
The PR does not remove the old names, only adds the new normalized ones to faciliate a transition period.
The size of a GUID is not platform-dependent, it's always a fixed number of bits. So I've updated guid to use fixed bit integer types rather than platform-dependent C integer types.
* AstGen: use Ast.zig helper methods to avoid copy pasting token counting logic
- take advantage of the `first_doc_comment` field we already have for
param AST nodes
* Add missing ZIR docs
Looking at the BufferedWriter assembly generated, one can see that is
has to do a lot of work, just to copy over some bytes and increase an
offset. This is because the LinearFifo is a much more general construct
than what BufferedWriter needs and the optimizer cannot prove that we
don't need to do this extra work.
* rename `entry` to `entry_symbol_name` for the zig build API
* integrate with `zig cc` command line options
* integrate with COFF linking with LLD
* integrate with self-hosted ELF linker
* don't put it in the hash for MachO since it is ignored
This reverts commit d48e4245b68bf25c7f41804a5012ac157a5ee546.
I have no idea why this is failing Drone CI, but in a branch, reverting
this commit solved the problem.
Instead use the standarized option for communicating the
zig compiler backend at comptime, which is `zig_backend`. This was
introduced in commit 1c24ef0d0b09a12a1fe98056f2fc04de78a82df3.
Calling `insert` on a `std.MultiArrayList` currently fails with a compiler error due to using a `try` without the `!` annotation on the return type
```zig
this.list.insert(allocator, 0, listener);
```
```zig
/Users/jarred/Build/zig/lib/std/multi_array_list.zig:192:13: error: expected type 'void', found '@typeInfo(@typeInfo(@TypeOf(std.multi_array_list.MultiArrayList(src.javascript.jsc.node.types.Listener).ensureUnusedCapacity)).Fn.return_type.?).ErrorUnion.error_set'
try self.ensureUnusedCapacity(gpa, 1);
```
AIR:
* `array_elem_val` is now allowed to be used with a vector as the array
type.
* New instructions: splat, vector_init
AstGen:
* The splat ZIR instruction uses coerced_ty for the ResultLoc, avoiding
an unnecessary `as` instruction, since the coercion will be performed
in Sema.
* Builtins that accept vectors now ignore the type parameter. Comment
from this commit reproduced here:
The accepted proposal #6835 tells us to remove the type parameter from
these builtins. To stay source-compatible with stage1, we still observe
the parameter here, but we do not encode it into the ZIR. To implement
this proposal in stage2, only AstGen code will need to be changed.
Sema:
* `clz` and `ctz` ZIR instructions are now handled by the same function
which accept AIR tag and comptime eval function pointer to
differentiate.
* `@typeInfo` for vectors is implemented.
* `@splat` is implemented. It takes advantage of `Value.Tag.repeated` 😎
* `elemValue` is implemented for vectors, when the index is a scalar.
Handling a vector index is still TODO.
* Element-wise coercion is implemented for vectors. It could probably
be optimized a bit, but it is at least complete & correct.
* `Type.intInfo` supports vectors, returning int info for the element.
* `Value.ctz` initial implementation. Needs work.
* `Value.eql` is implemented for arrays and vectors.
LLVM backend:
* Implement vector support when lowering `array_elem_val`.
* Implement vector support when lowering `ctz` and `clz`.
* Implement `splat` and `vector_init`.
This allows users to add file paths to device paths, which is often used
in methods like `boot_services.loadImage` and `boot_services.startImage`,
which take a device path with an additional file path appended to locate
the image.
UEFI uses `\` for paths exclusively. This changes std.fs.path to use `\`
for UEFI path joining. Also adds a few tests regarding it, specifically
in making sure double-separators do not result from path joining, as the
UEFI spec says to convert any that result from joining into single
separators (UEFI Spec Version 2.7, pg. 448).
- Add an `Metadata.isFree` helper method.
- Implement `Metadata.isTombstone` and `Metadata.isFree` with `@bitCast` then comparing to a constant. I assume `@bitCast`-then-compare is faster than the old method because it only involves one comparison, and doesn't require bitmasking.
- Summary of benchmarked changes (`gotta-go-fast`, run locally, compared to master):
- 3/4 of the hash map benchmarks used ~10% fewer cycles
- The last one (project Euler) shows 4% fewer cycles.
