While RISC-V hart is trapped into S-Mode, the S-Mode interrupt
CSR (SIE) is disabled by RISC-V hart. However the (SIE) is enabled
again by RestoreTPL, this causes the second S-Mode trap is triggered
by the machine mode (M-Mode)timer interrupt redirection. The SRET
instruction clear Supervisor Previous Privilege (SPP) to zero
(User mode) in the second S-Mode interrupt according to the RISC-V
spec. Above brings hart to the user mode (U-Mode) when execute
SRET in the nested S-Mode interrupt handler because SPP is set to
User Mode in the second interrupt. Afterward, system runs in U-Mode
and any accesses to S-Mode CSR causes the invalid instruction exception.

Being a compiler builtin, the type of __builtin_return_address is
already known to the compiler so no prototype is needed. Clang also
errors out when redeclaring certain builtins like this[1], though
currently only for ones with custom type checking. At the moment,
__builtin_return_address does not use custom type checking and so does
not trigger this error, however, the CHERI fork of LLVM, which will form
the basis of the toolchain for Arm's experimental Morello platform, does
use custom type checking for it, and so gives an error. Thus, simply
delete the unnecessary line.

Update INF file to use a [Pcd] section instead of a
[FixedPcd] section. [FixedPcd] should only be used in an
INF file if the source code looks up the PCD value using
the PcdLib FixedPcdGetxx() services. Using [FixedPcd]
forces a platform to configure the PCD to type FixedAtBuild.
In this case, PcdDebugPropertyMask supports PCD types
FixedAtBuild and PatchableInModule. Without this change
any platform that wants to use PcdDebugPropertyMask as
type PatchableInModule breaks the build.

Add the UT_EXPECT_ASSERT_FAILURE(FunctionCall, Status) macro
to the UnitTestLib that can be used to check if a function
under test triggers an ASSERT() condition. If an ASSERT()
condition is triggered, then the macro returns. If the
ASSERT() condition is not triggered, then the current unit
test fails with a status of UNIT_TEST_ERROR_TEST_FAILED.
If ASSERT()s are disabled, then this check for ASSERT()
behavior is not possible, and the check is skipped.
The global variable gUnitTestExpectAssertFailureJumpBuffer
is added to the UnitTestLib to save/restore context when
the UT_EXPECT_ASSERT_FAILURE(FunctionCall, Status) macro
is used. The UT_EXPECT_ASSERT_FAILURE() macro uses the
SetJump() service with this global variable. The UnitTestLib
service UnitTestDebugAssert() uses the LongJump() service
with this global to restore context if an ASSERT() is
triggered by the code under test.
Add UnitTestExpectAssertFailure() to the UnitTestLib class.
The UnitTestExpectAssertFailure() is called from the new
UT_EXPECT_ASSERT_FAILURE() macro after the status of this
macro check is known.
Add UnitTestDebugAssert() to the UnitTestLib class. The
UnitTestDebugAssert() service is the same as the DebugLib
DebugAssert() service and is invoked from the DebugLib
_ASSERT() macro if unit testing is enabled. This allows the
Unit Test Framework to know when code under test triggers an
ASSERT() condition.

Add a new version of BaseLib that is safe for use from host based
unit test applications. Host based unit test applications may need
to provide implementations of some BaseLib functions that provide
simple emulation to exercise the code under test. The structure
UNIT_TEST_HOST_BASE_LIB is filled in with services that provide
default emulation for BaseLib APIs that would normally generate
exceptions in a host based unit test application. This structure
allows an individual unit test to replace the default emulation of
a BaseLib service with an alternate version that is required by a
specific unit test. A global variable of type UNIT_TEST_HOST_BASE_LIB
is provided through the new UnitTestHostBaseLib library class.
Normally cmocka would be used to mock services the code under
test calls. However, the BaseLib is used by the Unit Test
Framework itself, so using a mocked interface is not possible.
The use of a structure to provide hooks for unit test is not
expected to be a common feature. It should only be required
for libraries that are used by both the Unit Test Framework and
the code under test where the code under test requires a
different behavior than the Unit Test Framework.

The mStatusString[] array is constructed as an array of pointer-to-char,
which means that on X64 or AARCH64, it is emitted as a single linear list
of 64-bit quantities, each containing the absolute address of one of the
string literals in memory.
This means that each string takes up 8 bytes of additional space, along
with 2 bytes of relocation data. It also means that extra work needs to
be done at runtime to process these relocations, every time a module is
loaded that incorporates this library.
So fix both issues, by splitting mStatusString into two arrays of char
arrays. The memory footprint decreases from 955 to 843 bytes, and given
that in the latter case, the overhead consists of 278 NUL characters rather
than 390 bytes worth of absolute addresses and relocation records, the size
of a compressed image is reduced even further. For example, when building
ArmVirtQemu.dsc in RELEASE mode for AARCH64 with the GCC5 profile, I get:
Before

So the uncompressed contents of the compressed image are 8 KB smaller,
whereas the resulting flash image (consisting of the compressed image
along with SEC, PEI_CORE and a set of PEIMs that execute in place) is
2 KB smaller.
