The debug compile unit was made from the first file of the initial
package. When build tags exclude all of its files, as for the
Windows-only tests/issues/test_issue_7547.odin on other targets, there
is none, and `odin test -debug` crashed on an out-of-bounds index.
Without `-debug` such a test builds and reports that there are no
tests to run, which `tests/issues/run.sh` relies on.
Fall back to the package's path for the compile unit's file.
A procedure with `@(disabled=true)` adds no dependency where it is
used, so that the calls to it, which are removed, do not pull it in.
Taking its value, e.g. `rawptr(assert)` with `-disable-assert`, then
referenced a procedure that was never generated, and LLVM asserted
"missing procedure 'assert'".
Add the dependency for every use that is not the callee of a call.
Casting a polymorphic procedure to `rawptr`, or to a procedure type
it cannot be specialized to, was accepted. There is no procedure to
take the address of, so the value came out nil, or the build hung, as
with `x := rawptr(avl.init_cmp)`. Assigning one to `rawptr` already
errors; make `cast` and `transmute` match. Casting to a procedure type
that specializes it still works, as assignment does.
Map keys of type `string16` used `default_hasher_string`, which reads
the length as a byte count; for a `string16` it counts u16 units, so
only the first half of the key was hashed. `cstring16` keys took the
same path and were read as a pointer and a length, which crashes.
Add `default_hasher_string16` and `default_hasher_cstring16` to the
runtime and use them for the generated key hashers, which are also
what the runtime and `intrinsics.type_hasher_proc` use.
Slicing a `[dynamic; N]T` skipped the bounds check when both indices
were constant, as is done for fixed arrays. But its length is only
known at runtime, so `a[0:3]` with a length of 2 silently returned
stale elements. Always check against the length, as for `[dynamic]T`.
`rawptr` pointed to a 1-byte `void` base type, so gdb printed every
rawptr, such as an allocator's `data`, as a C string. Describe it as a
pointer with no pointee type, which is how clang emits `void *`. This
also drops the address space it was given by mistake.
The name `cstring16` was passed with the length of `cstring`, so the
type was named `cstring`. Its characters, and those of `string16`,
were a 16-bit `wchar_t`, which gdb reads as UTF-32 on Linux and so
printed as garbage. On DWARF describe them as `char16_t`, a 16-bit UTF
character, which gdb reads as UTF-16. CodeView keeps `wchar_t`.
With the split debug types modules, every other module only declares a
record type. gdb resolves a declared struct by searching for its
definition, but a declared enum by taking the first symbol of that name,
which is the declaration itself in the module being looked at. Enums,
flag enum bit_sets and typeid showed as <incomplete type>, and every
`any` printed as nil since its `id` could not be read. gdb also cannot
find a declared type whose name starts with `#`, so #soa types were
incomplete too.
On DWARF, define these in every module that uses them, as clang does
with enums. CodeView resolves forward references by name, so Windows
keeps them in the types modules.
The checker lets a multi-value call fill several elements of a matrix
or #simd literal, as it does for arrays, but the constant part of the
literal was built as if each element were one value. A matrix literal
like `matrix[2,2]f32{three(), 4}` hit an assertion, and a #simd
literal put the constants after the call in the wrong lanes.
Skip over the values of a call when placing the constants, as the
array case already does.
