- more support for linux, android, freebsd, netbsd, openbsd, dragonfly
- centralize musl utils; musl logic is no longer intertwined with csu
- fix musl compilation to build crti/crtn for full archs list
- fix openbsd to support `zig build-lib -dynamic`
- initial dragonfly linking success (with a warning)
ancillary:
- fix emutls (openbsd) tests to use `try`
This addresses the use case of quickly reporting AstGen compile errors
for a file, for use with an IDE for example.
* Rename from `zig asgen` to `zig ast-check`
* It is now a command always available; not only in debug builds.
* Give it usage text and proper CLI parsing.
* Support reading from stdin when no positional arg is provided.
* `-t` flag makes it print textual ZIR. Without this flag, it only
provides compile errors.
* Support `--color` parameter to override the tty detection
closes#8871
We've settled on the nomenclature for the artifacts the compiler
pipeline produces:
1. Tokens
2. AST (Abstract Syntax Tree)
3. ZIR (Zig Intermediate Representation)
4. AIR (Analyzed Intermediate Representation)
5. Machine Code
Renaming `ir` identifiers to `air` will come with the inevitable
air-memory-layout branch that I plan to start after the 0.8.0 release.
This commits permits passing in static archives using the system
lib flag `-la`. With this commit, `zig ld` will now look firstly for
a dynamic library (which always takes precedence), and will fall back
on `liba.a` if the dylib is not found. The static archive is searched
for in the system lib search dirs like the dylibs.
This matches the behaviour for other targets in that
```
zig build-lib math.zig -target wasm32-freestanding
```
produces now `libmath.a` while
```
zig build-lib math.zig -dynamic -target wasm32-freestanding
```
is required to create a loadable Wasm module.
This matches the behaviour of other languages and leaves us
the ability to create actual static Wasm archives with
```
zig build-lib -static some.zig
```
which can then be combined with other Wasm object files and linked
into either a Wasm lib or executable using `wasm-ld`.
Update langref to reflect the fact we now ship WASI libc.
Rename include dir to match the convention:
from `wasm32-wasi` to `wasm-wasi-musl`
Add building stubs which will be used to build and cache WASI
libc sysroot.
This allows us to differentiate between regular locals and variables that create multiple locals
on the stack such as optionals and structs.
Now `struct_a = struct_b;` works and only updates a reference, rather than update all local's values.
Also created more test cases to test against this.
- When returning within a block, we must use an explicit return opcode. For now always emit the opcode when calling return, rather than using implicit return statements.
- Also added a more comprehensive test case to test for enum values using conditions
