2023-10-15wasm: lower min/max for floats to compiler_rtRobin Voetter
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. See also https://github.com/WebAssembly/design/issues/214

It didn't account for field alignement.

2023-10-03wasm: implement lowering anon declsLuuk de Gram
2023-10-03compiler: start handling anonymous decls differentlyAndrew Kelley
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.

2023-10-03codegen: fix field offsets in packed structsXavier Bouchoux
* 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()

2023-09-27Revert "compiler: don't use `@abs` builtin yet"Andrew Kelley
This reverts commit 21780899eb17a0cb795ff40e5fae6556c38ea13e. After this commit, a version of the compiler which supports the new `@abs` builtin is required.

Replaces the @fabs builtin with a new @abs builtins which accepts floats, signed integers and vectors of said types.
2023-09-21wasm: fix regression of C ABIAndrew Kelley
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 ```
