2024-10-18MdePkg: Fix null macros for XCODE5 and CLANGMike Beaton1-3/+0
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 &apos;EventNames&apos; 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).

2023-08-03ArmPkg: DefaultExceptionHandlerLib: Do Not Allocate MemoryOliver Smith-Denny2-15/+41
If gST->ConOut is available when Arm's DefaultExceptionHandler is running, AsciiPrint will get called to attempt to print to ConOut, in addition to the serial output. AsciiPrint calls AsciiInternalPrint in UefiLibPrint.c which in turn calls AllocatePool to allocate a buffer to convert the Ascii input string to a Unicode string to pass to ConOut->OutputString. Per the comment on DefaultExceptionHandler, we should not be allocating memory in the exception handler, as this can cause the exception handler to fail if we had a memory exception or the system state is such that we cannot allocate memory. It has been observed on ArmVirtQemu that exceptions generated in the memory handling code will fail to output the stack dump and CPU state that is critical to debugging because the AllocatePool will fail. This patch fixes the Arm and AARCH64 DefaultExceptionHandlers to not allocate memory when ConOut is available and instead use stack memory to convert the Ascii string needed for SerialPortWrite to the Unicode string needed for ConOut->OutputString. Correspondingly, ArmVirtQemu can now output the stack dump and CPU state when hitting an exception in memory code. Signed-off-by: Oliver Smith-Denny <osde@linux.microsoft.com>

2016-10-25ArmPkg/DefaultExceptionHandlerLib: replace AsciiStrCat() with AsciiStrCatS()Laszlo Ersek1-4/+14
AsciiStrCat() is deprecated / disabled under the DISABLE_NEW_DEPRECATED_INTERFACES feature test macro. The caller of CpsrString() is required to pass in "ReturnStr" with 32 CHAR8 elements. (DefaultExceptionHandler() complies with this.) "Str" is used to build "ReturnStr" gradually. Just before calling AsciiStrCat(), "Str" points to the then-terminating NUL character in "ReturnStr". The difference (Str - ReturnStr) gives the number of non-NUL characters we've written thus far, hence (32 - (Str - ReturnStr)) yields the number of remaining bytes in ReturnStr, including the ultimately terminating NUL character.

However, ASSERTs are compiled out in RELEASE builds, and since we simply return to wherever the ELR is pointing, we will not make any progress in case of synchronous aborts, and the same exception will be taken again immediately, resulting in the string 'Exception at 0x....' to be printed over and over again.
