* add a --system-linker-hack command line parameter to work around
poor LLD macho code. See #1535
* build.zig correctly handles static as well as dynamic dependencies
when building the self hosted compiler.
- no more unnecessary libxml2 dependency
- a static build on macos produces a completely static self-hosted
compiler for macos (except for libSystem as intended).
init-lib creates a working static library with tests, and
init-exe creates a working hello world with a `run` target.
both now have test coverage with the new "cli tests" file.
closes#1035
* fix race condition in std.event.Channel deinit
* add support to zig build for --no-rosegment
* add passing self-hosted compare-output test for calling a function
* put a global lock on LLD linking because it's not thread safe
* introduce std.atomic.Int
* add src-self-hosted/test.zig which is tested by the main test suite
- it fully utilizes the multithreaded async/await event loop so the
tests should Go Fast
* `stage2/bin/zig build-obj test.zig` is able to spit out an error if 2 exported
functions collide
* ability for `zig test` to accept `--object` and `--assembly`
arguments
* std.build: TestStep supports addLibPath and addObjectFile
Add wasm32 support to the build-obj, build-exe and build-lib commands
of the stage 1 compiler. Wasm64 should work transparently once it's
supported in upstream LLVM.
To export a function:
// lib.zig - for exposition, not necessary for this example
pub use @import("add.zig");
// add.zig
export fn add(a: i32, b: i32) i32 {
return a + b;
}
To import a function:
// cube.zig
extern fn square(x: i32) i32;
export fn cube(x: i32) i32 {
return x * square(x);
}
See #770
To help automatically translate code, see the
zig-fmt-pointer-reform-2 branch.
This will convert all & into *. Due to the syntax
ambiguity (which is why we are making this change),
even address-of & will turn into *, so you'll have
to manually fix thes instances. You will be guaranteed
to get compile errors for them - expected 'type', found 'foo'
Before we accepted a nullable allocator for some stuff like
opening files. Now we require an allocator.
Use the mem.FixedBufferAllocator pattern if a bound on the amount
to allocate is known.
This also establishes the pattern that usually an allocator is the
first argument to a function (possibly after "self").
fix docs for std.cstr.addNullByte
self hosted compiler:
* only build docs when explicitly asked to
* clean up main
* stub out zig fmt
The purpose of this is:
* Only one way to do things
* Changing a function with void return type to return a possible
error becomes a 1 character change, subtly encouraging
people to use errors.
See #632
Here are some imperfect sed commands for performing this update:
remove arrow:
```
sed -i 's/\(\bfn\b.*\)-> /\1/g' $(find . -name "*.zig")
```
add void:
```
sed -i 's/\(\bfn\b.*\))\s*{/\1) void {/g' $(find ../ -name "*.zig")
```
Some cleanup may be necessary, but this should do the bulk of the work.
* docgen supports obj_err code kind for demonstrating
errors without explicit test cases
* add documentation for `extern enum`. See #367
* remove coldcc keyword and add @setIsCold. See #661
* add compile errors for non-extern struct, enum, unions
in function signatures
* add .h file generation for extern struct, enum, unions
