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.
This was originally introduced in 4d48948b526337947ef59a83f7dbc81b70aa5723
but broken immediately afterwards in c8af00c66e8b6f62e4dd6ac4d86a3de03e9ea354.
* 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);
```
also use the common naming convention for glibc versions ("2.33" rather
than "2-33").
I also verified that these files are exactly identical to the previous
files from before zig updated to glibc 2.34.
__libc_start_main() from glibc.2.33.so or older needs to have a __libc_csu_init function callback parameter.
glibc-2.34 on the other hand has a different __libc_start_main() that does not use it,
and the start.S file from glibc-2.34 no longer construct the init function and pass null when calling __libc_start_main.
So, When targetting an older glibc, use the start.s files as they were in glibc-2.33 and construct the __libc_csu_init function.
fixes#10386#10512
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.
