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: Remove ARM32 Support from UnitTests

2025-09-25T22:04:10+00:00

edk2 is dropping support for the ARM32 architecture. This commit removes ARM32 code from UnitTests and moves the AARCH64 files to the top level. Signed-off-by: Oliver Smith-Denny

MdePkg/Test/DevicePathLib: Remove FreePool(NULL)

2024-11-08T17:22:14+00:00

Unit test checks if AppendDevicePathInstance() returns NULL. In those cases, AppendDevicePathInstance() does not allocate a device path, so the call to FreePool() must not be performed. Signed-off-by: Michael D Kinney

MdePkg: Fix some spelling mistakes found by cspell

2024-08-01T19:53:47+00:00

When cspell is installed (via `npm install cspell`), CI checks for spelling mistakes. There are currently a very large number of them: some are genuine mistakes while others are words or acryonyms that cspell doesn't know. Fix a few of the misspellings in MdePkg. Signed-off-by: Rebecca Cran

MdePkg/Library/BaseLib: Add BaseLib instance for host based unit tests

2020-07-15T05:25:21+00:00

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2800 Add a new version of BaseLib that is safe for use from host based unit test applications. Host based unit test applications may need to provide implementations of some BaseLib functions that provide simple emulation to exercise the code under test. The structure UNIT_TEST_HOST_BASE_LIB is filled in with services that provide default emulation for BaseLib APIs that would normally generate exceptions in a host based unit test application. This structure allows an individual unit test to replace the default emulation of a BaseLib service with an alternate version that is required by a specific unit test. A global variable of type UNIT_TEST_HOST_BASE_LIB is provided through the new UnitTestHostBaseLib library class. Normally cmocka would be used to mock services the code under test calls. However, the BaseLib is used by the Unit Test Framework itself, so using a mocked interface is not possible. The use of a structure to provide hooks for unit test is not expected to be a common feature. It should only be required for libraries that are used by both the Unit Test Framework and the code under test where the code under test requires a different behavior than the Unit Test Framework.
