MdePkg: Remove ARM32 Support

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

edk2 is dropping support for the ARM32 architecture. This commit removes the remaining ARM32 code from MdePkg. This also removes irrelevant VALID_ARCHITECTURES comments from infs that are not arch specific. Signed-off-by: Oliver Smith-Denny

MdePkg: Removing ipf which is no longer supported from edk2.

2018-09-25T15:48:21+00:00

Removing rules for Ipf sources file: * Remove the source file which path with "ipf" and also listed in [Sources.IPF] section of INF file. * Remove the source file which listed in [Components.IPF] section of DSC file and not listed in any other [Components] section. * Remove the embedded Ipf code for MDE_CPU_IPF. Removing rules for Inf file: * Remove IPF from VALID_ARCHITECTURES comments. * Remove DXE_SAL_DRIVER from LIBRARY_CLASS in [Defines] section. * Remove the INF which only listed in [Components.IPF] section in DSC. * Remove statements from [BuildOptions] that provide IPF specific flags. * Remove any IPF sepcific sections. Removing rules for Dec file: * Remove [Includes.IPF] section from Dec. Removing rules for Dsc file: * Remove IPF from SUPPORTED_ARCHITECTURES in [Defines] section of DSC. * Remove any IPF specific sections. * Remove statements from [BuildOptions] that provide IPF specific flags.

MdePkg/BaseSafeIntLib: Fix VS2015 IA32 NOOPT build failure

2018-02-28T03:44:14+00:00

v2: Add [LibraryClasses] section in INF file and refine coding style. There are VS2015 NOOPT IA32 build failure like below in BaseSafeIntLib. XXX.lib(XXX.obj): error LNK2001: unresolved external symbol __allmul XXX.lib(XXX.obj): error LNK2001: unresolved external symbol __allshl XXX.lib(XXX.obj): error LNK2001: unresolved external symbol __aullshr This patch replaces direct shift/multiplication of 64-bit integer with related function call to fix these failure.

MdePkg/BaseSafeIntLib: Add SafeIntLib class and instance

2018-01-25T17:42:20+00:00

https://bugzilla.tianocore.org/show_bug.cgi?id=798 SafeIntLib provides helper functions to prevent integer overflow during type conversion, addition, subtraction, and multiplication. Conversion Functions ==================== * Converting from a signed type to an unsigned type of the same size, or vice-versa. * Converting to a smaller type that could possibly overflow. * Converting from a signed type to a larger unsigned type. Unsigned Addition, Subtraction, Multiplication =============================================== * Unsigned integer math functions protect from overflow and underflow (in case of subtraction). Signed Addition, Subtraction, Multiplication ============================================ * Strongly consider using unsigned numbers. * Signed numbers are often used where unsigned numbers should be used. For example file sizes and array indices should always be unsigned. Subtracting a larger positive signed number from a smaller positive signed number with SafeInt32Sub() will succeed, producing a negative number, that then must not be used as an array index (but can occasionally be used as a pointer index.) Similarly for adding a larger magnitude negative number to a smaller magnitude positive number. * SafeIntLib does not protect you from such errors. It tells you if your integer operations overflowed, not if you are doing the right thing with your non-overflowed integers. * Likewise you can overflow a buffer with a non-overflowed unsigned index.
