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: Fix useless tests.

MdeModulePkg: Fix redundant call to RestoreTpl()

2024-09-04T00:53:54+00:00

Comments out a redundant call to RestoreTpl(). While this does not technically violate spec on raise/restore TPL, TPL should already be at the specified level. This extra call introduces an asymmetry between RaiseTpl and RestoreTpl calls, which makes analysis of TPL correctness more difficult and hampers certain non-standard TPL usages that some platforms require. Additionally, the two TPL variables were renamed to provide context for each of them. Signed-off-by: Kenneth Lautner

MdeModulePkg: Add extra RestoreTpl() call in DiskIo

2024-09-04T00:53:54+00:00

Adds a call to RestoreTpl() in DiskIo2ReadWriteDisk(). While the current implementation does not technically violate spec on raise/restore TPL, this extra call ensures symmetry between RaiseTpl and RestoreTpl calls, which makes analysis of TPL correctness simpler and permits certain non-standard TPL usages that some platforms require.

MdeModulePkg/RamDiskDxe: fix memory leak on error path.

2024-08-26T05:32:42+00:00

MdeModulePkg: Update code to be more C11 compliant by using func

2023-04-10T14:19:57+00:00

__FUNCTION__ is a pre-standard extension that gcc and Visual C++ among others support, while __func__ was standardized in C99. Since it's more standard, replace __FUNCTION__ with __func__ throughout MdeModulePkg. Signed-off-by: Rebecca Cran Reviewed-by: Michael D Kinney Reviewed-by: Ard Biesheuvel
