MdePkg: 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

MdePkg/BasePeCoffLib: Remove DEBUG() statements from runtime code

2025-01-29T18:42:13+00:00

PeCoffLoaderRelocateImageForRuntime() executes after boot services, and so it should not use DEBUG() prints at all, given that these may rely on MMIO mappings or other boot time facilities that are no longer available. So revert the changes in aedcaa3df8a2 ("MdePkg: Fix overflow issue in PeCoffLoaderRelocateImageForRuntime") that replaced code comments with DBEUG() statements. Signed-off-by: Ard Biesheuvel

MdePkg: Use SafeIntLib to handle overflow

MdePkg: Fix overflow issue in PeCoffLoaderRelocateImageForRuntime

2025-01-26T17:15:56+00:00

RelocDir->Size is a UINT32 value, and RelocDir->VirtualAddress is also a UINT32 value. The current code in PeCoffLoaderRelocateImageForRuntime does not check for overflow when adding RelocDir->Size to RelocDir->VirtualAddress. This patch uses SafeIntLib to ensure that the addition does not overflow. Signed-off-by: Sachin Ganesh
