MdeModulePkg: Replace include guards with #pragma once

2026-02-23T21:01:28+00:00

Replace traditional `#ifndef`/`#define`/`#endif` include guards with `#pragma` once. `#pragma once` is a widely supported preprocessor directive that prevents header files from being included multiple times. It is supported by all toolchains used to build edk2: GCC, Clang/LLVM, and MSVC. Compared to macro-based include guards, `#pragma once`: - Eliminates the risk of macro name collisions or copy/paste errors where two headers inadvertently use the same guard macro. - Eliminate inconsistency in the way include guard macros are named (e.g., some files use `__FILE_H__`, others use `FILE_H_`, etc.). - Reduces boilerplate (three lines replaced by one). - Avoids polluting the macro namespace with guard symbols. - Can improve build times as the preprocessor can skip re-opening the file entirely, rather than re-reading it to find the matching `#endif` ("multiple-include optimization"). - Note that some compilers may already optimize traditional include guards, by recognzining the idiomatic pattern. This change is made acknowledging that overall portability of the code will technically be reduced, as `#pragma once` is not part of the C/C++ standards. However, this is considered acceptable given: 1. edk2 already defines a subset of supported compilers in BaseTools/Conf/tools_def.template, all of which have supported `#pragma once` for over two decades. 2. There have been concerns raised to the project about inconsistent include guard naming and potential macro collisions. Approximate compiler support dates: - MSVC: Supported since Visual C++ 4.2 (1996) - GCC: Supported since 3.4 (2004) (http://gnu.ist.utl.pt/software/gcc/gcc-3.4/changes.html) - Clang (LLVM based): Since initial release in 2007 Signed-off-by: Michael Kubacki

MdeModulePkg/DebugSupportDxe: Fix incompatible pointer types

2025-11-21T16:33:06+00:00

GCC 15 enforces stricter type checking for function pointers. When passing EFI_PERIODIC_CALLBACK and EFI_EXCEPTION_CALLBACK to ManageIdtEntryTable, explicit casts to CALLBACK_FUNC are required to avoid incompatible pointer type errors. Add explicit casts at the call sites in RegisterPeriodicCallback and RegisterExceptionCallback functions.

MdeModulePkg/DebugSupportDxe: Fix type mismatches

2025-06-13T15:47:59+00:00

The RegisteredCallback field of IdtEntryTable is used to store the address of functions with different function prototypes depending on the ExceptionType. Add local variables with the correct function prototypes and evaluate the ExceptionType to assign correct local variable to the RegisteredCallback value and use local variable to call the registered callback function with the correct arguments for the ExceptionType. Update declaration of InterruptDistrubutionHub() to use the non-CPU specific EFI_SYSTEM_CONTEXT parameter type instead of the IA32 specific EFI_SYSTEM_CONTEXT_IA32 because this function is used for both IA32 and X64.
