When building OvmfPkg in RELEASE mode in the XCODE5 toolchain, the
ASSERT_EFI_ERROR change prevents this error:
.../MdePkg/Library/UefiMemoryAllocationLib/MemoryAllocationLib.c:141:15:
error: variable 'Status' set but not used [-Werror,-Wunused-but-set-variable]
EFI_STATUS Status;
^
which is currently stopping the build.
When building in RELEASE mode in the CLANGPDB toolchain,the DEBUG macro
change prevents this error:
.../edk2/OvmfPkg/VirtioSerialDxe/VirtioSerial.c:28:22: error:
variable 'EventNames' is not needed and will not be
emitted [-Werror,-Wunneeded-internal-declaration]
STATIC CONST CHAR8 *EventNames[] = {
^
which is currently stopping the build.
CLANGDWARF produces the same error as CLANGPDB above, if
-Wno-unneeded-internal-declaration is removed from its build flags.
With the null DEBUG macro change, this warning suppression
can be removed from CLANGDWARF, which is considered a benefit
as it has the potential to catch real coding errors. This is
done in a subsequent commit.
This commit has the desirable side effect that we no longer require
(and cannot use) explicit `#ifndef MDEPKG_NDEBUG` around items only
used in DEBUG macros. This requires the ArmPkg change made here to
be in the same commit as the MdePkg changes.
Note: In common with existing macros in EDK II, including the pre-existing
and unchanged DEBUG/NOOPT versions of the macros which are modified here,
we use the standard approach of adding `do { ... } while (FALSE)` wrapping
to ensure that the macros behave correctly with surrounding code
(e.g. require a following ';' and do not combine in unexpected ways with
nearby conditionals).
