[libc] Add support to compile some syscalls on 32 bit platform

2023-08-03T13:08:01+00:00

This patch adds a bunch of ifdefs to handle the 32 bit versions of
some syscalls, which often only append a 64 to the name of the syscall
(with exception of SYS_lseek -> SYS_llseek and SYS_futex ->
SYS_futex_time64)

This patch also tries to handle cases where wait4 is not available
(as in riscv32): to implement wait, wait4 and waitpid when wait4 is
not available, we check for alternative wait calls and ultimately rely
on waitid to implement them all.

In riscv32, only waitid is available, so we need it to support this
platform.

[libc][NFC] Move the mutex implementation into a utility class.

2021-08-26T18:49:20+00:00

This allows others parts of the libc to use the mutex types without
actually pulling in public function implementations.

Along the way, few cleanups have been done, like using a uniform type to
refer the linux futex word.

[libc][NFC] add includes for internal headers to all libc functions

this will make sure that all of the functions are using the correct

[libc] Switch to use a macro which does not insert a section for every libc function.

2021-01-08T23:52:35+00:00

Summary:
The new macro also inserts the C alias for the C++ implementations
without needing an objcopy based post processing step. The CMake
rules have been updated to reflect this. More CMake cleanup can be
taken up in future rounds and appropriate TODOs have been added for them.
