Optimize tolower(3)/toupper(3) from <ctype.h>. The tables in the BSD tolower/toupper are slower for ASCII than just doing the bit twiddling. We can't actually remove the tables on LP32, so move them into the "cruft" we keep around for backwards compatibility (but remove them for LP64 where they were never exposed). I noticed that the new bit-twiddling tolower(3) was performing better on arm64 than toupper(3). The 0xdf constant was requiring an extra MOV, and there isn't a BIC that takes an immediate value. Since we've already done the comparison to check that we're in the right range (where the bit is always set), though, we can EOR 0x20 to get the same result as the missing BIC 0x20 in just one instruction. I've applied that same optimization to towupper(3) too. Before: BM_ctype_tolower_n 3.30 ns 3.30 ns 212353035 BM_ctype_tolower_y 3.31 ns 3.30 ns 211234204 BM_ctype_toupper_n 3.30 ns 3.29 ns 214161246 BM_ctype_toupper_y 3.29 ns 3.28 ns 207643473 BM_wctype_towupper_ascii_n 3.53 ns 3.53 ns 195944444 BM_wctype_towupper_ascii_y 3.48 ns 3.48 ns 199233248 After: BM_ctype_tolower_n 2.93 ns 2.92 ns 242373703 BM_ctype_tolower_y 2.88 ns 2.87 ns 245365309 BM_ctype_toupper_n 2.93 ns 2.93 ns 243049353 BM_ctype_toupper_y 2.89 ns 2.89 ns 245072521 BM_wctype_towupper_ascii_n 3.34 ns 3.33 ns 212951912 BM_wctype_towupper_ascii_y 3.29 ns 3.29 ns 214651254 (Why do both the "y" and "n" variants speed up with the EOR change? Because the compiler transforms the code so that we unconditionally do the bit twiddling and then use CSEL to decide whether or not to actually use the result.) We also save 1028 bytes of data in the LP64 libc.so. Test: ran the bionic benchmarks and tests Change-Id: I7829339f8cb89a58efe539c2a01c51807413aa2d

Reorganize static TLS memory for ELF TLS For ELF TLS "local-exec" accesses, the static linker assumes that an executable's TLS segment is located at a statically-known offset from the thread pointer (i.e. "variant 1" for ARM and "variant 2" for x86). Because these layouts are incompatible, Bionic generally needs to allocate its TLS slots differently between different architectures. To allow per-architecture TLS slots: - Replace the TLS_SLOT_xxx enumerators with macros. New ARM slots are generally negative, while new x86 slots are generally positive. - Define a bionic_tcb struct that provides two things: - a void* raw_slots_storage[BIONIC_TLS_SLOTS] field - an inline accessor function: void*& tls_slot(size_t tpindex); For ELF TLS, it's necessary to allocate a temporary TCB (i.e. TLS slots), because the runtime linker doesn't know how large the static TLS area is until after it has loaded all of the initial solibs. To accommodate Golang, it's necessary to allocate the pthread keys at a fixed, small, positive offset from the thread pointer. This CL moves the pthread keys into bionic_tls, then allocates a single mapping per thread that looks like so: - stack guard - stack [omitted for main thread and with pthread_attr_setstack] - static TLS: - bionic_tcb [exec TLS will either precede or succeed the TCB] - bionic_tls [prefixed by the pthread keys] - [solib TLS segments will be placed here] - guard page As before, if the new mapping includes a stack, the pthread_internal_t is allocated on it. At startup, Bionic allocates a temporary bionic_tcb object on the stack, then allocates a temporary bionic_tls object using mmap. This mmap is delayed because the linker can't currently call async_safe_fatal() before relocating itself. Later, Bionic allocates a stack-less thread mapping for the main thread, and copies slots from the temporary TCB to the new TCB. (See *::copy_from_bootstrap methods.) Bug: http://b/78026329 Test: bionic unit tests Test: verify that a Golang app still works Test: verify that a Golang app crashes if bionic_{tls,tcb} are swapped Merged-In: I6543063752f4ec8ef6dc9c7f2a06ce2a18fc5af3 Change-Id: I6543063752f4ec8ef6dc9c7f2a06ce2a18fc5af3 (cherry picked from commit 1e660b70da625fcbf1e43dfae09b7b4817fa1660)
