As of 6249a24, align() is not allowed on packed struct fields
and as such the align(4) was removed from the first field of
EdidOverrideProtocolAttributes. The endgame here is packed struct
backed by explicit integers, in this case a u32, but until that
is implemented put the align(4) on the pointer to avoid breaking
someone's UEFI code in a hard to debug way.
This implements #10113 for the self-hosted compiler only. It removes the
ability to override alignment of packed struct fields, and removes the
ability to put pointers and arrays inside packed structs.
After this commit, nearly all the behavior tests pass for the stage2 llvm
backend that involve packed structs.
I didn't implement the compile errors or compile error tests yet. I'm
waiting until we have stage2 building itself and then I want to rework
the compile error test harness with inspiration from Vexu's arocc test
harness. At that point it should be a much nicer dev experience to work
on compile errors.
Beyond adding default zero-initialization, this commit changes undefined
initialization to zero, as some cases reserved the padding and on other
cases, I've found some systems act strange when giving uninit instead of
zero even when it shouldn't be an issue, one example being
FileProtocol.Open's attributes, which *should* be ignored when not
creating a file, but ended up giving an unrelated error.
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.
We already have a LICENSE file that covers the Zig Standard Library. We
no longer need to remind everyone that the license is MIT in every single
file.
Previously this was introduced to clarify the situation for a fork of
Zig that made Zig's LICENSE file harder to find, and replaced it with
their own license that required annual payments to their company.
However that fork now appears to be dead. So there is no need to
reinforce the copyright notice in every single file.
* `comptime const` is redundant
* don't use `extern enum`; specify a tag type.
`extern enum` is only when you need tags to alias. But aliasing tags
is a smell. I will be making a proposal shortly to remove `extern enum`
from the language.
* there is no such thing as `packed enum`.
* instead of `catch |_|`, omit the capture entirely.
* unused function definition with missing parameter name
* using `try` outside of a function or test
