* V1 - annotations for values of registers and memory to display result of instructions.
* Emulator telescope(), more x86 instructions
* Emulation change - keep track of before & after instruction execution. Telescope format correctly, read size taken into account
* Add config options to configure emulation and annotations, vmovaps alignment warning, string length in disasm telescope, cache previously annotated instructions
* Create PwndbgInstruction type for better typing and easier future development
* More consistent spacing, options to disable annotations, ADD instruction shows operands
* Rebase from dev
* Correctly go to .next address in disasm view (was incorrectly going to call targets)
* Precompute register str to reduce code duplication
* Correct telescope memory read width, bring target printing back to previous behavior when symbol can be resolved
* More consistent looking annotation spacing/padding, fixed edge case bugs with cached instructions
* Even cleaner padding
* Additional comments and debugging, ironed out last bugs
* debugging tight loops
* Cache fixed - nearpc only annotates what can be statically resolved
* lint and show instructions that cannot dereference
* Reapply btrace crash fix after rebase
* Less code duplication, implement XCHG and AND instructions, moved more methods from x86 subclass to superclass
* aarch64 set flags register in Unicorn correctly
* fix
* Don't recreate emulator regname->const map every time the emulator is instantiated
* Use emulation to set .next within enhancement
* Improve ret instruction target address setting
* Green checkmarks for jumps on all architectures
* Fixed .next and .target setting
* All architectures now have correct logic for determining .next and .target. Green checkmarks for taking conditional branches now appear for all architectures, added things to determine that type of branch being taken, and simplified printing by replacing symbol_addr with new field 'target_string'
* Instruction debug print fix
* Correct jump instruction checking
* Fixed target_string resolution
* Fix conditional jump check, also make default target resolution better
* target_const determined more accurately
* reverse iteration order of last change
* Pwndbg.condition is more retyped and more correct, make manual determinations of condition override the emulators (it can be incorrect in cases). Uncover why MIPS sometimes takes incorrect jumps in the emulator (delay slot)
* MIPS annotations work really good now. Jumps are correctly predicted (with green checkmarks). Implemented manual condition() function for MIPS. Only highlight the correct instance of instruction at PC when there are multiple in view (tight loops). Allow manual .condition to override emulator in determiningg .next.
* Additional debug info on instructions
* Print arch in instruction
* aarch64 branch fix
* aarch64 branch fix (real)
* lint
* Final changes - fixing .size error
* lint
* Add dev_dump_instruction command, add default memory read in resolve_used_value, update comments and remove .size from enhancedoperand as it only exists on x86
* More uniform spacing on annotations
* Various comments converted to docstrings, aarch64 enhancer created, post-rebase
* import aarch64
* Aarch64 mov, ldr, add, sub
* adrp
* ADR
* lint
* Fun with git rebase
* lint
* lint again after re-installing dependencies
* New caching strategy implemented to ensure no state caching when jumping large distances. Handled edge cases of user manually setting a register or memory, 'set regname=2'
* lint
* Fixed two regressions (nearpc shouldn't take jumps, even ones we know statically, and replace all constants in the assembly with symbols). Tweak tests to reflect new annotations
* lint
* one last test
* Fix chain format dereferencing for non-singleton lists, now correctly deferences and displays chains for future instructions when not emulating (dereference until pointer goes to writable memory)
* Add jumps-only setting to emulation (on, off, jumps-only), fixes to chain deferencing and enhancing
* Properly dereference memory before and after execution of instructions, adding a new before_value_resolved field (same for after). This also reduces code duplication.
* Debogusify the format()/telescoping dereferencing logic
* lint
* post-rebase fixes
* Fix case the breaks a test - don't attempt to read larger than ptrsize such as in SIMD instruction memory reads
* Typo in emulate setting
* Developer docs for annotations
* Fix case where emulator attempts to read and unpack very large, 16 byte+ wide values while telescoping
* Fix and test ctx disasm when disassembly-flavor changes
* New lib/cache.py: make caching great again
This commit fixes bugs with old caching (memoize.py) and makes it more
readable.

* Refactor TLS module
- Replace unreliable `__errno_location()` trick with `pthread_self()` to acquire TLS address
- Consolidate heap heuristics checks about TLS within the `pwndbg.gdblib.tls` module for better organization
* Bug fix for the `errno` command
Calling `__errno_location()` without locking the scheduler can cause another thread to inadvertently continue execution
* Refactor code about heap heuristics of thread-local variables
- Replace some checks with some functions in `pwndbg.gdblib.tls`
- Try to find tcache with `mp_.sbrk_base + 0x10` if the target is single-threaded
* Add tests for heap heuristics with multi-threaded
* Refacotr scheduler-locking related functions
- Move these functions into `pwndbg.gdblib.scheduler`
- Fetch the parameter value once (https://github.com/pwndbg/pwndbg/pull/1536#discussion_r1082549746)
* Avoid bug caused by GLIBC_TUNABLES
See https://github.com/pwndbg/pwndbg/pull/1536#discussion_r1083202815
* Add note about `set scheduler-locking on`
* Add comment for `lock_scheduler`
