Ok updated! |
This commit performs a few refactorings and fixes a bug as well. The changes here are: * The `thread_local!` in the `wasmtime` crate for trap information is removed. The thread local in the `wasmtime_runtime` crate is now leveraged to transmit trap information. * Panics in user-provided functions are now caught explicitly to be carried across JIT code manually. Getting Rust panics unwinding through JIT code is pretty likely to be super tricky and difficult to do, so in the meantime we can get by with catching panics and resuming the panic once we've resumed in Rust code. * Various take/record trap apis have all been removed in favor of working directly with `Trap` objects, where the internal trap object has been expanded slightly to encompass user-provided errors as well. This borrows a bit bytecodealliance#839 and otherwise will... Closes bytecodealliance#848

There was a problem hiding this comment.
Looks good 👍. Just a nit and a comment.

This commit performs a few refactorings and fixes a bug as well. The
changes here are:
The
thread_local!in thewasmtimecrate for trap information isremoved. The thread local in the
wasmtime_runtimecrate is nowleveraged to transmit trap information.
Panics in user-provided functions are now caught explicitly to be
carried across JIT code manually. Getting Rust panics unwinding
through JIT code is pretty likely to be super tricky and difficult to
do, so in the meantime we can get by with catching panics and resuming
the panic once we've resumed in Rust code.
Various take/record trap apis have all been removed in favor of
working directly with
Trapobjects, where the internal trap objecthas been expanded slightly to encompass user-provided errors as well.
