On s390x-linux, fstat() does not have nanosecond precision, but fstatat() does.
As a result, comparing Stat structs returned from these syscalls is doomed to
fail.
This works around the fact that LLVM and LLD both have broken support for the
small data area, yet the feature is on by default for all Hexagon CPUs.
I want to eventually replace this hack with a flag in update_cpu_features.zig
for marking features that should always be off by default and not be accessible
to users. That way, the compiler will have full control over them.
Until we actually figure out a version range for this, we shouldn't classify
this as using semver. Doing so results in a panic when trying to access the
version range since it's not in fact a semver value.
Only targets for which we don't source CPU models/features from LLVM should use
the fallback prong in this switch. Also make it exhaustive to catch similar
mistakes in the future.
At bare minimum, the compiler expects std.Target.<arch>.cpu.generic to work for
any given architecture when generating the builtin module. So rather than try to
hack that into working when the affected modules are omitted, just actually keep
them.
This affected lanai and xcore.
* Added error message 'ProcessNotFound' for reading and writing in a Linux
process.
This error occurs if the process to be read from or written to no longer exists.
Fixes#19875
* Added error message "ProcessNotFound" for error forwarding.
* Add error messgae for forwarding.
* Added message for forwarding.
* Error set completed.
* Fixed format error.
* Changed comments to doc comments.
These have no callers outside std.elf. Even if the standard library should
provide functions like these, std.elf is probably not the place, given how
general they are.
The dependency cache is shared amongst all Build objects. This is currently
done by allocating a single instance and storing a reference to it in each
Build object. However, the Graph object already exists to host shared
state so by moving it there we reuse the same pattern for shared state
and avoid an extra object on the heap.
although they would also pass simply reverted to master branch because
I made the deprecated API still work for now (to be removed after 0.14.0
is tagged)
Introduces `std.builtin.Panic` which is a complete interface for
panicking. Provide `std.debug.FormattedPanic` and
`std.debug.SimplePanic` and let the user choose, or make their own.
