let's try to keep this branch to solving one problem at a time
|
|
but I think it's a bad idea, so I'm going to back out the change
|

Not tested yet, but it builds.
This closes #761, and lays the groundwork for fixing the remaining
false positive "foo depends on itself" bugs, such as #624.
It also lays the groundwork for implementing ability to specify
alignment of fields (#1512).

only needed for freestanding targets.
also adds safety for `@intToPtr` when the address is zero.

Previously, global assembly was parsed expecting it to have
the template syntax. However global assembly has no inputs,
outputs, or clobbers, and thus does not have template syntax.
This is now fixed.
This commit also adds a compile error for using volatile
on global assembly, since it is meaningless.
closes #1515

Before, allocator implementations had to provide `allocFn`,
`reallocFn`, and `freeFn`.
Now, they must provide only `reallocFn` and `shrinkFn`.
Reallocating from a zero length slice is allocation, and
shrinking to a zero length slice is freeing.
When the new memory size is less than or equal to the
previous allocation size, `reallocFn` now has the option
to return `error.OutOfMemory` to indicate that the allocator
would not be able to take advantage of the new size.
For more details see #1306. This commit closes #1306.
This commit paves the way to solving #2009.
This commit also introduces a memory leak to all coroutines.
There is an issue where a coroutine calls the function and it
frees its own stack frame, but then the return value of `shrinkFn`
is a slice, which is implemented as an sret struct. Writing to
the return pointer causes invalid memory write. We could work
around it by having a global helper function which has a void
return type and calling that instead. But instead this hack will
suffice until I rework coroutines to be non-allocating. Basically
coroutines are not supported right now until they are reworked as
in #1194.

`builtin.TypeInfo.ErrorSet` is now `?[]Error`
instead of `struct{errors:[]Error}`.

`--static` is no longer an option. Instead, Zig makes things as static
as possible by default. `-dynamic` can be used to choose a dynamic
library rather than a static one.
`--enable-pic` is a new option. Usually it will be enabled
automatically, but in the case of build-exe with no dynamic libraries
on Linux or freestanding, Zig chooses off by default.

* in Zig build scripts, getOutputPath() is no longer a valid function
to call, unless setOutputDir() was used, or within a custom make()
function. Instead there is more convenient API to use which takes
advantage of the caching system. Search this commit diff for
`exe.run()` for an example.
* Zig build by default enables caching. All build artifacts will go
into zig-cache. If you want to access build artifacts in a convenient
location, it is recommended to add an `install` step. Otherwise
you can use the `run()` API mentioned above to execute programs
directly from their location in the cache. Closes #330.
`addSystemCommand` is available for programs not built with Zig
build.
* Please note that Zig does no cache evicting yet. You may have to
manually delete zig-cache directories periodically to keep disk
usage down. It's planned for this to be a simple Least Recently
Used eviction system eventually.
* `--output`, `--output-lib`, and `--output-h` are removed. Instead,
use `--output-dir` which defaults to the current working directory.
Or take advantage of `--cache on`, which will print the main output
path to stdout, and the other artifacts will be in the same directory
with predictable file names. `--disable-gen-h` is available when
one wants to prevent .h file generation.
* `@cImport` is always independently cached now. Closes #2015.
It always writes the generated Zig code to disk which makes debug
info and compile errors better. No more "TODO: remember C source
location to display here"
* Fix .d file parsing. (Fixes the MacOS CI failure)
* Zig no longer creates "temporary files" other than inside a
zig-cache directory.
This breaks the CLI API that Godbolt uses. The suggested new invocation
can be found in this commit diff, in the changes to `test/cli.zig`.

a different root package directory besides the one inferred from the
root source file
and a corresponding build.zig API:
foo.setMainPkgPath(path)
