This would be superior of course. Ideally being able to limit maximum runtime down to one hours.

I run a small CI system which starts relatively beefy preemptible instances for jobs. Normally those instances are terminated by the job scheduler as soon as there's nothing more to do. But it's a great peace of mind knowing they

gcc have -Og which turns on optimization steps that can be enabled without sacrificing debugability.

In theory yes. However, in practice static linking with glibc pulls in a lot of dead weight, musl comes to the rescue though: test.c: int main(int argc, char **argv) { printf("hello world\n"); return 0; } Dynamic

I wonder how it handles the stricter memory ordering from x86? For example, this code: void store_value_and_unlock(int *p, int *l, int v) { *p = v; __sync_lock_release(l, 0); } on x86_64 compiles to: mov dword pt

io_uring requires userspace to access it using a well-defined load/store memory ordering. Care must be taken to make sure the compiler does not reorder instructions but also to use the correct load/store instructions so hardware d

So it's a Windows and MacOS bug then? Ie, no shadow should fall on io_uring really? That said, nice dig figuring this out. These type of bugs can be really frustrating to round up.

In my experience (having embedded both spidermonkey and duktape) is that if embedding is not a primary use case for the engine it can get messy and complicated to update (lots of api breakage etc). This was the reason I switched from spide
