[libc] Implement `exit` for the GPU partially

2023-04-28T01:32:00+00:00

This patch implements the `exit` function on the GPU. This required
breaking the entrypoints calling eachother on `linux` since this doesn't
work with a non-aliased target. This is only partial support because
full support requires a malloc / free implementation for the exit
callbacks array.

[libc] Re-enable functions from signal.h and re-enable abort.

2022-09-30T07:31:50+00:00

They were disabled because we were including linux/signal.h from our
signal.h. Linux's signal.h is not designed to be included from user
programs as it causes a lot of non-standard name pollution. Also, it is
not self-contained. This change defines types and macros relevant for
signal related syscalls within libc's headers and removes inclusion of
Linux headers.

This patch enables the funtions only for x86_64. They will be enabled
for aarch64 also in a follow up patch after testing.

[libc][NFC] Remove all Linux specific code to respective linux/ directories

2022-02-08T18:32:18+00:00

These were all the non OS agnostic implementations I could find in general directories.

Currently none of these functions are actually enabled, but for when they do it makes sense that they be in linux/ specific directories.
