debug: disable the new unwinder on aarch64-macos

dwarf: implement aarch64 default register rules

dwarf: fixup rules for setting ip

dwarf: update the pc register

dwarf: fix the unwinder using the incorrect row from the FDE in certain cases

dwarf: write the CFA as SP before the register update, in case the SP itself is updated by a column rule

macho: don't scan all eh_frame entries, instead follow the offset from the __unwind_info directly

dwarf: add explicit_fde_offset to support more optimal __unwind_info dwarf lookups

test: add a test for dwarf embedded in coff

debug: load the macho unwind sections from the already-mapped image

dwarf: fixup integer overflow in readEhPointer

use eh_frame from the mapped binary if available

dwarf: add abi.stripInstructionPtrAuthCode

compilation: pass omit_frame_pointer through to builtin.zig

macho: remove unnecessary checks

debug: fixup an inconsistency in the getcontext implementation on aarch64-macos

tests: use a more portable way of determining the return address in the test code

dwarf: use cie.return_address_register instead of assuming it's in the IP register

debug: fixup have_getcontext

debug: fixup last_error being printed too many times

debug: fix initialization of the optional fields on StackIterator

macho: add aarch64 implementation to unwindFrame

debug: add relocateContext

macho: add unwindFrame which can unwind stack frames using the __unwind_info section

dwarf: add ExpressionError to work around the compiler not being able to infer it

dwarf: skip register tests on unimplemented arch / os, add tests for type convesions

dwarf: fixup default endianness in ExpressionOptions, add control flow tests

dwarf: fixup regBytes for the case where there is no context support

debug: add dupeContext, store a pointer to a copy of ThreadContext on UnwindContext

dwarf: implement constx,addrx, begin adding DWARF expression tests

debug: rename StackTraceContext to ThreadContext

dwarf: expression fixups for non-64bit arches, check call_frame_context when writing expressions

dwarf: add expression writer

dwarf: introduce ExpressionContext, add more expression opcodes

darwin: update mcontext_t definition for aarch64 to add neon state

debug: fixup base address calculations for macho

dwarf: don't dupe function names, as they are backed by the memory mapped sections

debug: rework how unwind errors are printed, and add module name lookup for linux

dwarf: add support for DWARF5 DW_AT_ranges in subprograms, add DebugRangeIterator

dwarf: fix logic error in eh_frame_hdry binary search

debug: de-duplicate some code in macos ModuleDebugInfo

c: fixup getcontext

c: musl doesn't implement getcontext, so defer to our implementation in that case

test: add standalone test for DWARF unwinding with -fomit-frame-pointer

c: add getcontext

debug: fix reading -gdwarf generated debug sections in COFF files

linux: rework getcontext to closer match the specification (saved IP/SP match the state after it would return)

debug: x86 unwinding support, more unwinding fixes

debug: enhance writeCurrentStackTrace to use context-based unwinding when available

dwarf: add support for .debug_frame and CIE version 4

linux: add getcontext for x86_64

update to new builtin syntax

dwarf: use eh_frame length if it's available

add more safety checks when searching for eh_frame entries using findEntry

- rebase and update to lastest master

dwarf: fixup pointer cast

dwarf: add support for .eh_frame_hdr when unwinding

debug: fix memory leak when an error occurs opening a pdb file

debug: more fixups for mips linux not having ucontext_t

debug: fixing more compile errors on arches that I hadn't tested on yet

dwarf: fixes for non-64 bit systems

debug: use an explicit context type instead of anytype for dumpStackTraceFromBase, update crash_report to use this for exceptions

dwarf: fixup for sort changes

debug: fixup context detection for wasi

fmt and cleanup

- rework CFI instruction parsing to not use std.meta

dwarf: implement more register mappings, fix up macos compile

dwarf: implement more register number mappings
