Fix fdRead: handle io.Reader corner cases

1

These are to handle corner cases described in [`io.Reader`](https://pkg.go.dev/io#Reader). For a partial read `readv` really shouldn't continue reading into the following buffer. And according to [`io.Reader`](https://pkg.go.dev/io#Reader), callers should handle any...

Do you think it would be worthwhile to maintain an example of Zig in the wazero repository? I extended the allocation example for Zig. I can open a PR if...

Optimize memory bulk operations: fill on x86

3

Nobody answered me in #512 🥲, so I decided on my own what implementation to use. Instead of a copy loop: ```asm .loop: MOVB [dst], value DEC size CMP size,...

compiler: optimize bulk memory operations

8

Currently the assembly implementations of `memory.copy` and `memory.fill` (and table equivalents) are pretty native and simply do the for-loop copying one by one. amd64: https://github.com/tetratelabs/wazero/blob/266320e257e6a0496781aa740c79e61833d7d83a/internal/wasm/jit/jit_impl_amd64.go#L3536 arm64: https://github.com/tetratelabs/wazero/blob/266320e257e6a0496781aa740c79e61833d7d83a/internal/wasm/jit/jit_impl_arm64.go#L3071 Therefore, there's plenty...

Compile functions at runtime

Is it (or will it) be possible to extend a running wasm instance with a new function? E.g. compile a function from wasm binary representation and add it to the...

Serialize a compiled module

12

**Describe the solution you'd like** Is it possible to replicate [this feature](https://pkg.go.dev/github.com/wasmerio/wasmer-go/wasmer#Module.Serialize) from wasmer-go? Compiling a module results in a significant number of allocations, so I'd like to compile a...
