Breakpad’s DWARF line table reader only understood line tables at the
level of DWARF 2. This wasn’t a problem because LLVM only produced line
tables at this level, even when generating DWARF 4. But LLVM would like
to output DWARF 4 line tables when generating DWARF 4, and Breakpad
needs to understand this format. (Meanwhile, it seems that GCC has used
DWARF 4 line tables with DWARF 4 output since 4.5.0, 2010-04-14.)
DWARF 3 line tables are fully compatible with DWARF 2 (assuming that
nothing needs “prologue end,” “epilogue begin,” or “isa”, and opcodes
related to these fields are properly skipped). DWARF 4 changes the line
number program header slightly to include a “maximum operations per
instruction” field. This field must be recognized, but can safely be
ignored (and assumed to be always 1) if VLIW architectures are not
supported (they aren’t). DWARF 4 also introduces a “discriminator”,
whose opcode can also be skipped if these values are not needed (they
shouldn’t be).
This recognizes the “maximum operations per instruction” field when
processing DWARF 4 line tables, but asserts that its value is 1 and
otherwise ignores it.
This is not compatible with VLIW architectures that set this field to a
value other than 1. Such architectures are irrelevant to Breakpad, and
mainline GCC and the proposed LLVM patch always set this field to 1.
There are other things that could be extracted from DWARF 3 and 4 line
tables that aren’t currently extracted (although these are currently
irrelevant to Breakpad too).

are considered modified. Lastly, if one of the modified

'relative_path' variable does need to be resolved using
realpath, since gyp or the underlying build system might cd
to it before looking for the 'path' target

The main motivation for this change is to handle very large stack
traces, normally the result of infinite recursion. This part is
actually fairly simple, relaxing a few self-imposed limits on how
many frames we can unwind and the max size for stack memory.
Relaxing these limits requires stricter and more consistent checks for
stack unwinding. There are a number of unwinding invariants that apply
to all the platforms:
1. stack pointer (and frame pointer) must be within the stack memory
(frame pointer, if preset, must point to the right frame too)
2. unwinding must monotonically increase SP
(except for the first frame unwind, this must be a strict increase)
3. Instruction pointer (return address) must point to a valid location
4. stack pointer (and frame pointer) must be appropriately aligned
This change is focused on 2), which is enough to guarantee that the
unwinding doesn't get stuck in an infinite loop.
1) is implicitly validated part of accessing the stack memory
(explicit checks might be nice though).
4) is ABI specific and while it may be valuable in catching suspicious
frames is not in the scope of this change.
3) is also an interesting check but thanks to just-in-time compilation
it's more complex than just calling
StackWalker::InstructionAddressSeemsValid()
and we don't want to drop parts of the callstack due to an overly
conservative check.

The bfd and gold linkers create segments like this: r/x, r/w where
the r/x segment covers the start of the ELF file.
lld's segments look like this: r, r/x, r/w where the r segment covers
the start of the ELF file.
So we cannot rely on the location of the r/x to tell where the start
of the ELF is. But we can still rely on the r and r/x mappings being
adjacent. So what we do is when we see an r segment followed by an r/x,
merge the r into the r/x and claim that it is executable. This way,
the minidump writer will continue to see a single executable segment
covering the entire executable.
Testing: "make check" passes when breakpad is compiled with
lld compiled from trunk (requires bug fix from LLVM r303689).
Also patched change into chromium and tested these builds:
$ cat args.gn
is_chrome_branded = true
is_debug = false
is_official_build = true
use_lld = true
allow_posix_link_time_opt = false
is_cfi = false
$ cat args.gn
target_os = "android"
target_cpu = "arm"
is_debug = false
is_official_build = true
is_chrome_branded = true
With both builds breakpad_unittests passes and
chrome/chrome_modern_public_apk create good minidumps after navigating
to chrome://inducebrowsercrashforrealz (checked that minidump contains
stack trace entry for content::HandleDebugURL).

When writing a minidump on Linux, we called clone() in
linux/handler/exception_handler.cc with the CLONE_FILES flag. If the
parent process died while the child waited for the continuation signal,
the write side of the pipe 'fdes' stayed open in the child. The child
would not receive a SIGPIPE and would wait forever.
To fix this, we clone without CLONE_FILES and then close the
read-side of fdes in the master before the ptrace call. That way, if the
master dies, the child will receive a SIGPIPE and will die, too.
To test this I added a sleep() call before SendContinueSignalToChild()
and then killed the master, manually observing that the child would die,
too.

If another memory region of interest (e.g. a thread stack) randomly happens
to lie immediately before the page allocated by this test, the memory
regions can be coalesced in the minidump generated. Relax this test so it
correctly handles the case where the expected 256 bytes around the IP aren't
at the start of the minidump memory region.
Alternatively, that could be avoided by reserving the page before the page
used for this test, in which case this test is degenerate with
InstructionPointerMemoryMinBound and can be removed.
