- limit expected-output to main source file;
ie. tolerate changes to start.zig
- when mode != .Debug the function name is now symbolically represented;
ie. tolerate changes in llvm optimizer effects on the callstack
- cleanup how test cases are specified
- add test case predicates for excluding by arch, os or custom fn
rowSize used to return null if all the elements were placed on the same
line as the right brace, making the rendering logic skip the whole set
of elements.
Given the usage of rowSize let's just drop the null and always return
the number of elements.
Fixes#8423
This branch adds "builtin" and "std" to the import table when using the
self-hosted backend.
"builtin" gains one additional item:
```
pub const zig_is_stage2 = true; // false when using stage1 backend
```
This allows the std lib to do conditional compilation based on detecting
which backend is being used. This will be removed from builtin as soon
as self-hosted catches up to feature parity with stage1.
Keep a sharp eye out - people are going to be tempted to abuse this.
The general rule of thumb is do not use `builtin.zig_is_stage2`. However
this commit breaks the rule so that we can gain limited start.zig support
as we incrementally improve the self-hosted compiler.
This commit also implements `fullyQualifiedNameHash` and related
functionality, which effectively puts all Decls in their proper
namespaces. `fullyQualifiedName` is not yet implemented.
Stop printing "todo" log messages for test decls unless we are in test
mode.
Add "previous definition here" error notes for Decl name collisions.
This commit does not bring us yet to a newly passing test case.
Here's what I'm working towards:
```zig
const std = @import("std");
export fn main() c_int {
const a = std.fs.base64_alphabet[0];
return a - 'A';
}
```
Current output:
```
$ ./zig-cache/bin/zig build-exe test.zig
test.zig:3:1: error: TODO implement more analyze elemptr
zig-cache/lib/zig/std/start.zig:38:46: error: TODO implement structInitExpr ty
```
So the next steps are clear:
* Sema: improve elemptr
* AstGen: implement structInitExpr
This refactor inserts an offset table into wasm's data section
where each offset points to the actual data region.
This means we can keep offset indexes consistant and do not
have to perform any computer to determine where in the data section
something like a static string exists. Instead during runtime
it will load the data offset onto the stack.
The following code caused an assertion to be hit:
```
pub fn main() void {
var e: anyerror!c_int = error.Foo;
const i = e catch 69;
assert(69 - i == 0);
}
```
