This adds benchmarks around module instantiation using criterion.
Both the default (i.e. on-demand) and pooling allocators are tested
sequentially and in parallel using a thread pool.
Instantiation is tested with an empty module, a module with a single page
linear memory, a larger linear memory with a data initializer, and a "hello
world" Rust WASI program.
* Upgrade to the latest versions of gimli, addr2line, object
And adapt to API changes. New gimli supports wasm dwarf, resulting in
some simplifications in the debug crate.
* upgrade gimli usage in linux-specific profiling too
* Add "continue" statement after interpreting a wasm local dwarf opcode
On Windows, `metadata` computes only partial metadata results, which don't
include what WASI needs for the `inode` field in `readdir` results. cap-std
has a `full_metadata` function which is able to include this extra
information, however it has more strict access requirements, so it sometimes
fails even when plain `metadata` would succeed.
Make WASI's `readdir` silently skip over files that can't be accessed by
`full_metadata`. These files wouldn't be openable in any other way by
WASI programs, so the only benefit of listing them would be to
let applications know that they exist. This allows it to avoid failing
and avoid returning bogus results.
This is part of a fix for bytecodealliance/cap-std#169.
This commit implements the `--allow-unknown-exports` option to the CLI run
command that will ignore unknown exports in a command module rather than
return an error.
Fixes#2587.
On s390x, SIGILL and SIGFPE are delivered with the PSW address
pointing *after* the faulting instruction, while SIGSEGV and
SIGBUS are delivered with the PSW address pointing *to* the
faulting instruction. In order to support this, the common
code trap handler has to distinguish between those cases.
Also, enable SIGFPE on s390x (just like on x86).
