wasm: lower min/max for floats to compiler_rt
The min and max builtins in Zig have some intricate behavior
related to floats, that is not replicated with the min and max
wasm instructions or using simple select operations. By lowering
these instructions to compiler_rt, handling around NaNs is done
correctly.

de78caf9c4 wasm: implement lowering anon decls 2023-10-03 12:49:29 -07:00
Andrew Kelley
c0b5512544 compiler: start handling anonymous decls differently
Instead of explicitly creating a `Module.Decl` object for each anonymous
declaration, each `InternPool.Index` value is implicitly understood to
be an anonymous declaration when encountered by backend codegen.

The memory management strategy for these anonymous decls then becomes to
garbage collect them along with standard InternPool garbage.

In the interest of a smooth transition, this commit only implements this
new scheme for string literals and leaves all the previous mechanisms in
place.

* add nested packed struct/union behavior tests
 * use ptr_info.packed_offset rather than trying to duplicate the logic from Sema.structFieldPtrByIndex()
 * use the container_ptr_info.packed_offset to account for non-aligned nested structs.
 * dedup type.packedStructFieldBitOffset() and module.structPackedFieldBitOffset()

1c02e58fc0 Revert "compiler: don't use @abs builtin yet"
This reverts commit 21780899eb17a0cb795ff40e5fae6556c38ea13e.

After this commit, a version of the compiler which supports the new
`@abs` builtin is required.

221295b7db wasm: fix regression of C ABI
It seems the webassembly backend does not want the exception that
`structFieldAlignmentExtern` makes for 128-bit integers. Perhaps that
logic should be modified to check if the target is wasm.

Without this, this branch fails the C ABI tests for wasm, causing this:
```
wasm-ld: warning: function signature mismatch: zig_struct_u128
>>> defined as (i64, i64) -> void in cfuncs.o
>>> defined as (i32) -> void in test-c-abi-wasm32-wasi-musl-ReleaseFast.wasm.o
