Fail to compile bionic/tests/complex_test.cpp when updating compiler due
to the conflict.
Bug: b/346349678
Test: change the clang version and then run mm to build

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.
Test: adb shell /data/nativetest64/bionic-unit-tests/bionic-unit-tests --gtest_filter=*tls*

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.

This is fairly conservative, touching only those functions (such as feof()) where it's clearly an error to not use the return value.
Also fix a test that was ignoring the return value of feof() (because it was just checking whether the function could take the lock, and genuinely didn't care about the result).

A lot of people who see these via pitot or whatever don't even think to look at the real tombstone. Make it explicit that this is what they should do next. Also, since we have the numbers, say exactly what we mean by "most common".

I only came to improve the signature mismatch error, but I was then annoyed by the copy & paste of the other checks.
get_chunk_size() seems to be deliberately avoiding any checks, though I think that might be a bug, and there should be a get_chunk_size() that _does_ check for most callers, and a get_chunk_size_unchecked() for the <sys/thread_properties.h> stuff that seems to want to only be "best effort" (but does still have _some_ possibility of aborting, in addition to the possibility of segfaulting).
Also a bit of "include what you use" after cider complained about all the unused includes in bionic_allocator.h.
