Cast the constant (which should probably be unsigned in the kernel headers, but isn't), rather than the already [correctly] unsigned expression involving `c_cflag`.
This came up when there was a suggestion on the linux-api mailing list [https://lore.kernel.org/linux-api/be31d737-8263-4e59-8b30-7221ee0549fc@cs.ucla.edu/T/#mdd466d7eaefe8805de7b0cecf013c5cddb04c660] to maybe change the signedness of the constants; this was the only build breakage that would result in AOSP from doing so.

Similar to mmap(), this confuses me every time I look at it. Move it out
of the way, and make it clearer that this is just junk that can be
deleted when we remove 32-bit support.
Also improve coverage by adding a test for the varargs special case.

Also group all the RELR/arm64/riscv64 bits together rather than mixing them up slightly as we'd done so far.

Fail to compile bionic/tests/complex_test.cpp when updating compiler due
to the conflict.

libz is no longer statically linked into libunwindstatck, so needs to be

Add basic assembly stubs for TLS Descriptor support in the dynamic
linker, and enable several code paths related to TLSDESC for RISC-V.
Note: This patch requires an updated toolchain that supports TLSDESC
for RISC-V, and the `-mtls-dialect=` compiler option specifically.

Every time I look at mmap.cpp, I fail to realize it's only built for ILP32.
Also improve some of the commentary in SYSCALLS.TXT and legacy_32_bit_support.cpp.

clang-19 and later default to C++14 sized deallocation. Currently we don't have C23's C equivalent of free_sized(), so we just implement these in terms of free() for now.

I was actually here to add some new documentation, but realized there wasn't really a good place to put it...

Not a security problem, but definitely a bug if you're calling this and ignoring the result, since it has no side-effects.
(All of the more important functions -- realloc() especially -- are already annotated.)

This is just POSIX nonsense. Android, iOS/macOS, the BSDs, and glibc all have getpagesize(). Window doesn't, but Windows doesn't have sysconf(3) either, so there's not a strong "portability" argument to be had there!

The setjmp implementation is correct, but this comment was wrong, and we were missing the implementation of the test. This would be slightly simpler if we enabled Zfa in the build system and qemu, but this works for now.
