Give +x to the .wasm file if it is an executable and the OS is WASI.
Some systems may be configured to execute such binaries directly. Even
if that is not the case, it means we will get "exec format error" when
trying to run it rather than "access denied", and then can react to that
in the same way as trying to run an ELF file from a foreign CPU
architecture.
This is part of the strategy to unify RunStep and EmulatableRunStep.
- Use .flash as the default address space for functions on AVR
- Return .flash as the address space for function pointers on AVR
without explicit address space
Previously, this API had pid, to be used on POSIX systems, and handle,
to be used on Windows.
This commit unifies the API, defining an Id type that is either the pid
or the HANDLE depending on the target OS.
This commit also prepares for the future by allowing one to import via
`std.process.Child` which is the fully qualified namespace that I intend
to migrate to in the future.
Also add `std.fs.has_executable_bit` for doing conditional compilation.
This adds the linux syscalls for chmod and fchmodat, as well as the
extern libc function declarations.
Only `fchmodat` is added to `std.os`, and it is not yet added to std.fs.
Make the Keccak permutation public, as it's useful for more than
SHA-3 (kMAC, SHAKE, TurboSHAKE, TupleHash, etc).
Our Keccak implementation was accepting f as a comptime parameter,
but always used 64-bit words and 200 byte states, so it actually
didn't work with anything besides f=1600.
That has been fixed. The ability to use reduced-round versions
was also added in order to support M14 and K12.
The state was constantly converted back and forth between bytes
and words, even though only a part of the state is actually used
for absorbing and squeezing bytes. It was changed to something
similar to the other permutations we have, so we can avoid extra
copies, and eventually add vectorized implementations.
In addition, the SHAKE extendable output function (XOF) was
added (SHAKE128, SHAKE256). It is required by newer schemes,
such as the Kyber post-quantum key exchange mechanism, whose
implementation is currently blocked by SHAKE missing from our
standard library.
Breaking change: `Keccak_256` and `Keccak_512` were renamed to
`Keccak256` and `Keccak512` for consistency with all other
hash functions.
When there is a diamond dependency, reuse a *Module instead of creating
a redundant one using the same build.zig file. Otherwise, the compile
error "file exists in multiple modules" would occur.
Partial revert of 1e963053d0ff67361b587b046a917375e963d5e9. Now that
lldb has a new method for accessing this data that does not require
manual updating, there is no longer any reason to share this data.
And make it not do any installation, only objcopying. We already have
install steps for doing installation.
This commit also makes ObjCopyStep properly integrate with caching.
Many `Type`s can correspond to the same `CType`, so this reduces the
number of used locals by 27760 when compiling only-c.
Also, disabled some tests that were only passing by accident and
shouldn't really be considered working.
