stage2: resolve file before putting them into cache
|
|
Before this commit:
```
$ zig test lib/std/fs/test.zig --main-pkg-path lib/std --zig-lib-dir lib
2170 passed; 37 skipped; 0 failed.
```
After this commit:
```
$ zig test lib/std/fs/test.zig --main-pkg-path lib/std --zig-lib-dir lib
All 45 tests passed.
```
This matches stage1 behavior:
```
$ zig test -fstage1 lib/std/fs/test.zig --main-pkg-path lib/std --zig-lib-dir lib
All 45 tests passed.
```
All tests are still run if `zig test` is run directly on `lib/std/std.zig`:
```
$ zig test lib/std/std.zig --main-pkg-path lib/std --zig-lib-dir lib
2170 passed; 37 skipped; 0 failed.
```
`zig build test-std` is unaffected by this change.
Closes #12926

This was an accidental misuse of the Cache API which intends to call
resolve on all file paths going into it. This one callsite was failing
to do that; fixed now.
Fixes relative file paths from making it into the global cache manifest.
See #13050

Fixes original comment of #12399

* the root struct decl name is fully qualified
this prevents error messages containing 'main.main'
* avoid declared here note when file struct is missing a member
It always points at the start of the file which might contain another
container misleading the user.

Previously if a decl failed its capture scope would be deallocated and
set to undefined which would then lead to invalid dereference in
`zirClosureGet`. To avoid this set the capture scope to a special
failed state and fail the current decl with dependency failure if
the failed state is encountered in `zirClosureGet`.

Currently, `zig build-exe -fno-emit-bin --verbose-air src/main.zig`
results in no output at all. With this refactor, it dumps AIR
and then exits without invoking LLVM, as expected

When instantiating a generic function, there is a period of time where
the function is inserted into monomorphed_funcs map, but is not yet
initialized. Despite semantic analysis being single-threaded, generic
function instantiation can happen recursively, meaning that the hash
and equality functions for monomorphed_funcs entries are potentially
invoked for an uninitialized function.
This problem was mitigated by pre-setting the hash field on the newly
allocated function, however it did not solve the problem for hash
collisions in which case the equality function would be invoked. That it
was solved for hash() but not eql() explains why the problem was
difficult to observe. I tested this patch by temporarily sabotaging the
hash and making it always return 0.
This fix is centered on adding a new field to Module.Fn which is the one
checked by eql() and is populated pre-initialization.

Previously, Zig had inconsistent semantics for an enum like this:
`enum(u8){zero = 0}`
Although in theory this can only hold one possible value, the tag
`zero`, Zig no longer will treat the type this way. It will do loads and
stores, as if the type has runtime bits.
Closes #12619
Tests passed locally:
* test-behavior
* test-cases
|
|
When removing generic function instantiations from monomorphed_funcs, we
need to first make sure the function is generic, otherwise the hash map
tries to access the `hash` field of the function which is undefined.

This was present in stage1 but missing from self-hosted.

* riscv64: adjust alignment and size of 128-bit integers.
* take ofmt=c into account for ABI alignment of 128-bit integers and
structs.
* Type: make packed struct support intInfo
* fix f80 alignment for i386-windows-msvc

This is likely the cause of the flaky test failures in master branch.
Since we have some test coverage for incremental compilation, it's not
OK to leave proper memory management of Fn objects as "TODO".
|
|
Now the backing integer of a packed struct type may be explicitly
specified with e.g. `packed struct(u32) { ... }`.

Replace param_names and anytype_args fields inside of Fn with functions
|
|
|
|
anytype_args field was replaced with isAnytypeParam function.
|
|
Removed the copy of param_names inside of Fn and changed to
implementation of getParamName to fetch to parameter name from the ZIR.
The signature of getParamName was also changed to take an additional
*Module argument.
