72c118f4a6 Add and handle various dwarf5 addrx forms.
Given the almost nonexistent direct dwarfreader tests, I think
the best way to test these dwarf5 additions will be to add a full
dwarf5 compilation unit similar to the ones used incidentally in
the other tests. But I can't do that until enough dwarf5 is
correctly implemented.

e780d58fd7 Use breakpad_getcontext on all Linux platforms missing getcontext
getcontext is also not available on musl libc, so generalize
breakpad_getcontext so it can be used as a fallback for non-Android
platforms as well.

On x86_64 and i386, ucontext_t uses an Android-specific offset for
storage of FP registers, since its sigset_t differs in size. So,
make the definition of MCONTEXT_FPREGS_MEM and UCONTEXT_FPREGS_MEM_OFFSET
conditional on whether we are building for Android.

On glibc and musl, signal.h and asm/sigcontext.h can't be included
together, so in breakpad_context_unittest.cc, only compare the libc
and kernel _fpstate when on Android.

a5fa28ddf0 Fix some bugs in CheckMicrodumpContents
The crash address from the microdump was never checked against
anything. Instead, the test was checking the value of a constant.

On 32-bit systems, an intptr_t cannot represent kCrashAddress
(0xDEADDEAD), causing a failure when the crash address is parsed
from the microdump. Instead, use uintptr_t, which matches the type
of kCrashAddress.

75ca6a193d Use public fpregset_t type to define fpstate_t
The _libc_fpstate struct tag is an implementation detail of glibc,
and musl uses a different struct tag, _fpstate.

Unfortunately, the public type fpregset_t is a pointer type, so is
not suitable for allocating storage, or referring to constant
storage. Instead, we can use std::remove_pointer<fpregset_t>::type
to refer to the pointed-to type, regardless of the struct tag.

On musl libc, including the incorrect header path results in a

On glibc, pthread_yield is exactly equivalent to sched_yield[1].

On bionic, pthread_yield is also not available, so on Android, the
tests define a wrapper that just calls sched_yield. This wrapper
is no longer necessary if we just use sched_yield in the first
place.

c7522272ff Add "type" option to sym_upload sym-upload-v2 mode.
- "sym-upload-v2" protocol now supports specifying a symbol file "type".
- Known types are "breakpad" (default option, previously this was only
effectively the only option), "elf", "pe", "macho", "debug_only", "dwp",
"pdb", and "dsym".
- When type other than breakpad is specified, sym_upload tool requires
the code_file and debug_id value (that it otherwise would have gotten
from the text of the Breakpad symbol file).
- This ultimately means that sym_upload can be used to upload native
symbol files now, in addition to Breakpad symbol files.

5e1c53a442 android: truncate lower of two overlapping modules
Previously, the processor truncated the upper of two
overlapping module ranges to compensate for incorrect
reporting of module ranges by the Breakpad client.
Crashpad correctly reports module load ranges, so
this truncation strategy is no longer necessary.

However, when partitioned libraries are used, the base
library may have a range which encompasses the other
partitions. When this is combined with the truncate
upper merge strategy, the base library's executable
segment is truncated causing symbolization failures.

This patch changes Android's merge strategy to truncate
the lower range (which is still the base library, but
this strategy truncates from the high end of the
library's range, instead of its base).

13c1568702 arm64: recover register X30(LR) when fallback to frame pointer unwinder
Stackwalk can't recover caller's register X30($LR) value by STACK CFI info.
This will lead unwinding stop immediately when fallback to frame pointer unwinder.

This PR will use try to use second last frame to recover register X30($LR) by frame pointer.
And we will give up correction if STACK CFI info doesn't agree with frame pointer info.

e5ef907c2e ios: build for arm64e
When __DARWIN_OPAQUE_ARM_THREAD_STATE64 is set (by default when building
for arm64e), fp, lr, sp, pc, and flags (but not x or cpsr) in thread
state are prepended with "__opaque" and intended to be accessed via
supplied getters which may also authenticate pointers. We don't want to
authenticate those pointers (since we expect they may be invalid and
want to recover those invalid values) so access them directly.

f32b83eb08 Enable reading DWARF4 CIEs with 32 bit addresses.
- Reading DWARF4 CIEs was added in
https://chromium-review.googlesource.com/c/breakpad/breakpad/+/406012 but it
was only enabled for 64bit builds, since it would error out if the CIE
address size was not 8 bytes.
- Added a unit test to ensure that 32bit continues to work.

5bc3092b30 Add a variable to allow adding an extra include path for LSS.
I have a project where we are trying to include breakpad as a git
submodule. The only problem getting it to build with ndk-build is that
the linux_syscall_support.h header is missing. Normally, this header
would be downloaded by the depot_tools. But we cannot install
depot_tools on our CI machines.

So, we would like to include the header as a separate submodule in our
repo. The only change we would need to make to breakpad to make that
work is to add this optional variable to the C header search path. In
the normal case, this variable will not be set and nothing will be
different. But we can set the variable to allow us to build without
installing depot_tools.

I have manually tested this using a separate project that links to
breakpad in this way.

47cd498384 dump_syms: handle forward reference DWARF attributes
DW_AT_specification and DW_AT_abstract_origin attributes carry
references to other DIEs. Nothing prevents the DIEs referred to from
appearing later in .debug_info than the DIE containing the referring
attribute, but dump_syms incompletly implemented its handling of these
references, and was only able to resolve them when they were
back-references.

This will fix the chronic warnings produced by dump_syms of the form:

dump_syms: the DIE at offset <offset> has a {DW_AT_specification,
DW_AT_abstract_origin} attribute referring to the die at offset
<offset>, which either was not marked as {a declaration, an inline}, or
comes later in the file
