C++23 adds std::float16_t but also std::bfloat16_t. https://github.com/cppfastio/fast_io/blob/bd32ed1f8fbc6cc44a541601fefc8e331f355b37/include/fast_io_unit/floating/punning.h#L137 @jk-jeon What's the value here?

please make EH opcode clear

1

I do not know how EH works and only your https://pengowray.github.io/wasm-ops/ tells exactly how the instruction works.

is opcode of catch being 0x00?

wasi 64 support by adding _wasm64 API sets

8

See: https://github.com/WebAssembly/wasi-libc/pull/444 I think the wasi API can have its _i64 version to implement ptr for 64 bit instead of making the API the same. This will make things much...

Why did you make errno.h, system_error and charconv freestanding?

5

charconv is not possible to implement in freestanding without creating a static lib and -ffreestanding might change the definitions of errno (since errno.h does not exist in the toolchain)

WASI 64

I am working on creating the wasi64 interface. Put an issue here so we can have a discussion. https://github.com/WebAssembly/wasi-libc/pull/444

performance issue for std::span on wasm C calling convention

```cpp #include #include void baz(::std::size_t *ptr,::std::size_t n) noexcept; void foo(::std::span sp) noexcept { baz(sp.data(),sp.size()); } void bar(::std::size_t *ptr,::std::size_t n) noexcept { baz(ptr,n); } ``` ``` _Z3fooNSt3__14spanImLm4294967295EEE: # @_Z3fooNSt3__14spanImLm4294967295EEE .functype _Z3fooNSt3__14spanImLm4294967295EEE...

Support wasm64

13

I need to make changes to the "c_header.rs" file because there are numerous instances where "size_t" is mistakenly identified as "uint32_t," which is incompatible with wasm64.
