On our bots, debug unit tests take around 2.5x as long to complete as
release tests on Linux, 3x as long on macOS, and 6x as long on Windows.
Our tests are fast, so this does not particularly matter, but SDE
inflates a 13 second test run to 8 minutes. On Windows (MSVC), where we
don't but would like to test with SDE, the difference between optimized
and unoptimized is even larger, and test runs are slower in general.
This suggests running SDE tests in release mode. Release mode tests,
however, are less effective because they do not include asserts. Thus,
add a RelWithAsserts option.
(Chromium does something similar. I believe most of the test-running
configurations on the critical path run is_debug = false and
dcheck_always_on = true.)

The first attempt involved using Linux's support for hardware
breakpoints to detect when assembly code was run. However, this doesn't
work with SDE, which is a problem.
This version has the assembly code update a global flags variable when
it's run, but only in non-FIPS and non-debug builds.
Update-Note: Assembly files now pay attention to the NDEBUG preprocessor
symbol. Ensure the build passes the symbol in. (If release builds fail
to link due to missing BORINGSSL_function_hit, this is the cause.)

Unfortunately, this requires partially reverting
https://boringssl-review.googlesource.com/31324. This is a mess.
While clang proper includes a fuzzer driver, Chromium doesn't use it.
Chromium builds exclusively with fuzzer-no-link and links to its own
copy of the fuzzer runtime[1]. As of [2], Chromium's clang (which we use
on bots) no longer includes the driver, so we must mimic them.
However, Chromium's setup is somewhat questionable because
fuzzer-no-link pulls in libclang_rt.fuzzer_no_main which still includes
most of libclang_rt.fuzzer, just not the one main function[3]. It
appears Chromium is actually linking two copies of
libclang_rt.fuzzer_no_main. Hopefully this mostly works out as Chromium's
clang and libFuzzer should be relatively aligned, but it's not a good
assumption for our build, which can take other Clangs too.
Thus, if you pass -DFUZZ=1 as-is, we will assume you are using a
"normal" Clang with all its relevant runtimes intact. If, however, you
are using Chromium clang, you must drop the matching libFuzzer where the
bots expected it and build with -DLIBFUZZER_FROM_DEPS=1.
This involves no changes to the bots because we never actually unwound
all the LIBFUZZER_FROM_DEPS bits before.

This uses the x86 trap flag and libunwind to test CFI works at each
instruction. For now, it just uses the system one out of pkg-config and
disables unwind tests if unavailable. We'll probably want to stick a
copy into //third_party and perhaps try the LLVM one later.
This tester caught two bugs in P-256 CFI annotations already:
I47b5f9798b3bcee1748e537b21c173d312a14b42 and
I9f576d868850312d6c14d1386f8fbfa85021b347
An earlier design used PTRACE_SINGLESTEP with libunwind's remote
unwinding features. ptrace is a mess around stop signals (see group-stop
discussion in ptrace(2)) and this is 10x faster, so I went with it. The
question of which is more future-proof is complex:
- There are two libunwinds with the same API,
https://www.nongnu.org/libunwind/ and LLVM's. This currently uses the
system nongnu.org for convenience. In future, LLVM's should be easier
to bundle (less complex build) and appears to even support Windows,
but I haven't tested this. Moreover, setting the trap flag keeps the
test single-process, which is less complex on Windows. That suggests
the trap flag design and switching to LLVM later. However...
- Not all architectures have a trap flag settable by userspace. As far
as I can tell, ARMv8's PSTATE.SS can only be set from the kernel. If
we stick with nongnu.org libunwind, we can use PTRACE_SINGLESTEP and
remote unwinding. Or we implement it for LLVM. Another thought is for
the ptracer to bounce SIGTRAP back into the process, to share the
local unwinding code.
- ARMv7 has no trap flag at all and PTRACE_SINGLESTEP fails. Debuggers
single-step by injecting breakpoints instead. However, ARMv8's trap
flag seems to work in both AArch32 and AArch64 modes, so we may be
able to condition it on a 64-bit kernel.
Sadly, neither strategy works with Intel SDE. Adding flags to cpucap
vectors as we do with ARM would help, but it would not emulate CPUs
newer than the host CPU. For now, I've just had SDE tests disable these.
Annoyingly, CMake does not allow object libraries to have dependencies,
so make test_support a proper static library. Rename the target to
test_support_lib to avoid
https://gitlab.kitware.com/cmake/cmake/issues/17785
Update-Note: This adds a new optional test dependency, but it's disabled
by default (define BORINGSSL_HAVE_LIBUNWIND), so consumers do not need
to do anything. We'll probably want to adjust this in the future.

Valgrind's checking of uninitialised memory behaves very much like a
check for constant-time code: branches and memory indexes based on
uninitialised memory trigger warnings. Therefore, if we can tell
Valgrind that some secret is “uninitialised”, it'll give us a warning if
we do something non-constant-time with it.
This was the idea behind https://github.com/agl/ctgrind. But tricks like
that are no longer needed because Valgrind now comes with support for
marking regions of memory as defined or not. Therefore we can use that
API to check constant-time code.
This CL defines |CONSTTIME_SECRET| and |CONSTTIME_DECLASSIFY|, which are
no-ops unless the code is built with
|BORINGSSL_CONSTANT_TIME_VALIDATION| defined, which it isn't by default.
So this CL is a no-op itself so far. But it does show that a couple of
bits of constant-time time are, in fact, constant-time—seemingly even
when compiled with optimisations, which is nice.
The annotations in the RSA code are a) probably not marking all the
secrets as secret, and b) triggers warnings that are a little
interesting:
The anti-glitch check calls |BN_mod_exp_mont| which checks that the
input is less than the modulus. Of course, it is because the input is
the RSA plaintext that we just decrypted, but the plaintext is supposed
to be secret and so branching based on its contents isn't allows by
Valgrind. The answer isn't totally clear, but I've run out of time on
this for now.

Chromium builds with this warning on. This lets us notice problems (of
which there were only one) sooner. I'll try to align the other warnings
in a follow-up.

Fixes failed compile with [-Werror=implicit-fallthrough=], which is
default on gcc-7.x on distributions like fedora.
Enabling no implicit fallthrough for more than just clang as well to
catch this going forward.

Someone tried to build us with Ubuntu's MinGW. This is too old to be
supported (the tests rather badly fail to build), but some of the fixes
will likely be useful for eventually building Clang for Windows
standalone too.

I'm not sure why these aren't on by default, but Chromium does this too.
Colors are nice.

In particular, this removes -fno-rtti, which allows the OSS-Fuzz folks
to run with -fsanitize=vptr. See
https://github.com/google/oss-fuzz/issues/741.
(-fsanitize=vptr isn't especially useful right now as we're just
starting with C++ support, but perhaps it'll be more useful in the
future.)

Short-term, we will need to use these macros and build without RTTI when
defining any virtual base class. Long-term, it would be good to remove
these constraints, but it will require some downstream work.

This serves two purposes:
1. Make sure we don't accidentally write "throw" or "catch" in our code.
2. If a C project statically links to our libssl.a, they'll use gcc
rather than g++ as the linker which does not pull in the C++ runtime.
-fno-exceptions cuts out the C++ runtime dependency. (Though we will
need to give up on this should we attempt to allow a runtime
dependency in the future.)

This will catch failures standalone before they reach consumers.
