#ifndef dwarf_eh_h
#define dwarf_eh_h
#include "dwarf.h"
/* This header file defines the format of a DWARF exception-header
section (.eh_frame_hdr, pointed to by program-header
PT_GNU_EH_FRAME). The exception-header is self-describing in the
sense that the format of the addresses contained in it is expressed
as a one-byte type-descriptor called a "pointer-encoding" (PE).
The exception header encodes the address of the .eh_frame section
and optionally contains a binary search table for the
Frame Descriptor Entries (FDEs) in the .eh_frame. The contents of
.eh_frame has the format described by the DWARF v3 standard
(http://www.eagercon.com/dwarf/dwarf3std.htm), except that code
addresses may be encoded in different ways. Also, .eh_frame has
augmentations that allow encoding a language-specific data-area
(LSDA) pointer and a pointer to a personality-routine.
Details:
The Common Information Entry (CIE) associated with an FDE may
contain an augmentation string. Each character in this string has
a specific meaning and either one or two associated operands. The
operands are stored in an augmentation body which appears right
after the "return_address_register" member and before the
"initial_instructions" member. The operands appear in the order
in which the characters appear in the string. For example, if the
augmentation string is "zL", the operand for 'z' would be first in
the augmentation body and the operand for 'L' would be second.
The following characters are supported for the CIE augmentation
string:
'z': The operand for this character is a uleb128 value that gives the
length of the CIE augmentation body, not counting the length
of the uleb128 operand itself. If present, this code must
appear as the first character in the augmentation body.
'L': Indicates that the FDE's augmentation body contains an LSDA
pointer. The operand for this character is a single byte
that specifies the pointer-encoding (PE) that is used for
the LSDA pointer.
'R': Indicates that the code-pointers (FDE members
"initial_location" and "address_range" and the operand for
DW_CFA_set_loc) in the FDE have a non-default encoding. The
operand for this character is a single byte that specifies
the pointer-encoding (PE) that is used for the
code-pointers. Note: the "address_range" member is always
encoded as an absolute value. Apart from that, the specified
FDE pointer-encoding applies.
'P': Indicates the presence of a personality routine (handler).
The first operand for this character specifies the
pointer-encoding (PE) that is used for the second operand,
which specifies the address of the personality routine.
If the augmentation string contains any other characters, the
remainder of the augmentation string should be ignored.
Furthermore, if the size of the augmentation body is unknown
(i.e., 'z' is not the first character of the augmentation string),
then the entire CIE as well all associated FDEs must be ignored.
A Frame Descriptor Entries (FDE) may contain an augmentation body
which, if present, appears right after the "address_range" member
and before the "instructions" member. The contents of this body
is implicitly defined by the augmentation string of the associated
CIE. The meaning of the characters in the CIE's augmentation
string as far as FDEs are concerned is as follows:
'z': The first operand in the FDE's augmentation body specifies
the total length of the augmentation body as a uleb128 (not
counting the length of the uleb128 operand itself).
'L': The operand for this character is an LSDA pointer, encoded
in the format specified by the corresponding operand in the
CIE's augmentation body.

/* This file defines the runtime-support routines for dynamically
generated code. Even though it is implemented as part of libunwind,
it is logically separate from the interface to perform the actual
unwinding. In particular, this interface is always used in the
context of the unwind target, whereas the rest of the unwind API is
used in context of the process that is doing the unwind (which may be
a debugger running on another machine, for example).
Note that the data-structures declared here server a dual purpose:
when a program registers a dynamically generated procedure, it uses
these structures directly. On the other hand, with remote-unwinding,
the data-structures are read from the remote process's memory and
translated into internalized versions. To facilitate remote-access,
the following rules should be followed in declaring these structures:
(1) Declare a member as a pointer only if the the information the
member points to needs to be internalized as well (e.g., a
string representing a procedure name should be declared as
"const char *", but the instruction pointer should be declared
as unw_word_t).
(2) Provide sufficient padding to ensure that no implicit padding
will be needed on any of the supported target architectures. For
the time being, padding data structures with the assumption that
sizeof (unw_word_t) == 8 should be sufficient. (Note: it's not
impossible to internalize structures with internal padding, but
it does make the process a bit harder).
(3) Don't declare members that contain bitfields or floating-point
values.
(4) Don't declare members with enumeration types. Declare them as
int32_t instead. */

/* Memory pools provide simple memory management of fixed-size
objects. Memory pools are used for two purposes:
o To ensure a stack can be unwound even when a process
is out of memory.
o To ensure a stack can be unwound at any time in a
multi-threaded process (e.g., even at a time when the normal
malloc-lock is taken, possibly by the very thread that is
being unwind).
To achieve the second objective, memory pools allocate memory
directly via mmap() system call (or an equivalent facility).
The first objective is accomplished by reserving memory ahead of
time. Since the memory requirements of stack unwinding generally
depends on the complexity of the procedures being unwind, there is
no absolute guarantee that unwinding will always work, but in
practice, this should not be a serious problem. */

/* Fast stack backtrace for AArch64.
This is used by backtrace() implementation to accelerate frequent
queries for current stack, without any desire to unwind. It fills
BUFFER with the call tree from CURSOR upwards for at most SIZE
stack levels. The first frame, backtrace itself, is omitted. When
called, SIZE should give the maximum number of entries that can be
stored into BUFFER. Uses an internal thread-specific cache to
accelerate queries.
The caller should fall back to a unw_step() loop if this function
fails by returning -UNW_ESTOPUNWIND, meaning the routine hit a
stack frame that is too complex to be traced in the fast path.
This function is tuned for clients which only need to walk the
stack to get the call tree as fast as possible but without any
other details, for example profilers sampling the stack thousands
to millions of times per second. The routine handles the most
common AArch64 ABI stack layouts: CFA is FP or SP plus/minus
constant offset, return address is in LR, and FP, LR and SP are
either unchanged or saved on stack at constant offset from the CFA;
the signal return frame; and frames without unwind info provided
they are at the outermost (final) frame or can conservatively be
assumed to be frame-pointer based.
Any other stack layout will cause the routine to give up. There
are only a handful of relatively rarely used functions which do
not have a stack in the standard form: vfork, longjmp, setcontext
and _dl_runtime_profile on common linux systems for example.
On success BUFFER and *SIZE reflect the trace progress up to *SIZE
stack levels or the outermost frame, which ever is less. It may
stop short of outermost frame if unw_step() loop would also do so,
e.g. if there is no more unwind information; this is not reported
as an error.
The function returns a negative value for errors, -UNW_ESTOPUNWIND
if tracing stopped because of an unusual frame unwind info. The
BUFFER and *SIZE reflect tracing progress up to the error frame.
Callers of this function would normally look like this:
unw_cursor_t cur;
unw_context_t ctx;
void addrs[128];
int depth = 128;
int ret;
unw_getcontext(&ctx);
unw_init_local(&cur, &ctx);
if ((ret = unw_tdep_trace(&cur, addrs, &depth)) < 0)
{
depth = 0;
