Translate C: Put an alignCast in c style pointer casts to allow opaque types to cast properly in C macros
Translate C: add test case for aligning opaque types in pointer casts
Translate C: Fix @typeId -> @typeInfo
Add test case to run_translated_c for casting from pointer to opaque type
Zig now supports a more fine-grained sense of what is native and what is
not. Some examples:
This is now allowed:
-target native
Different OS but native CPU, default Windows C ABI:
-target native-windows
This could be useful for example when running in Wine.
Different CPU but native OS, native C ABI.
-target x86_64-native -mcpu=skylake
Different C ABI but otherwise native target:
-target native-native-musl
-target native-native-gnu
Lots of breaking changes to related std lib APIs.
Calls to getOs() will need to be changed to getOsTag().
Calls to getArch() will need to be changed to getCpuArch().
Usage of Target.Cross and Target.Native need to be updated to use
CrossTarget API.
`std.build.Builder.standardTargetOptions` is changed to accept its
parameters as a struct with default values. It now has the ability to
specify a whitelist of targets allowed, as well as the default target.
Rather than two different ways of collecting the target, it's now always
a string that is validated, and prints helpful diagnostics for invalid
targets. This feature should now be actually useful, and contributions
welcome to further improve the user experience.
`std.build.LibExeObjStep.setTheTarget` is removed.
`std.build.LibExeObjStep.setTarget` is updated to take a CrossTarget
parameter.
`std.build.LibExeObjStep.setTargetGLibC` is removed. glibc versions are
handled in the CrossTarget API and can be specified with the `-target`
triple.
`std.builtin.Version` gains a `format` method.
Previously it was a tagged union which was one of:
* baseline
* a specific CPU
* a set of features
Now, it's possible to have a CPU but also modify the CPU's feature set
on top of that. This is closer to what LLVM does.
This is more correct because Zig's notion of CPUs (and LLVM's) is not
exact CPU models. For example "skylake" is not one very specific model;
there are several different pieces of hardware that match "skylake" that
have different feature sets enabled.
