2026-06-09MdePkg: Replace manual alignment checks with helper macrosMingjie Shen1-1/+1
Replace manual alignment checks with IS_ALIGNED() and ADDRESS_IS_ALIGNED(). Convert the following bitmask and modulo forms: - ((E & ((PowOf2Expr) - ONE)) == ZERO) - ((E & ((PowOf2Expr) - ONE)) != ZERO) - ((E % (PowOf2Expr)) == ZERO) - ((E % (PowOf2Expr)) != ZERO) to the corresponding helper macro forms: + IS_ALIGNED (E, PowOf2Expr) + !IS_ALIGNED (E, PowOf2Expr) PowOf2Expr is limited to known power-of-two expressions, including SIZE_* and BASE_* macros, EFI_PAGE_SIZE, CPU_STACK_ALIGNMENT, RUNTIME_PAGE_ALLOCATION_GRANULARITY, sizeof() of UEFI integer types (e.g. BOOLEAN, CHAR16, UINT32, UINTN) and pointer types, and 1 << E1 expressions. Address checks that cast the checked value to UINTN are written with ADDRESS_IS_ALIGNED(). The change was generated with the Coccinelle semantic patch below. ```smpl @power_of_2_expr@ expression PowOf2Expr; expression E1; typedef BOOLEAN, CHAR8, CHAR16, INT8, UINT8, INT16, UINT16, INT32, UINT32, INT64, UINT64, INTN, UINTN; type ScalarType = { BOOLEAN, CHAR8, CHAR16, INT8, UINT8, INT16, UINT16, INT32, UINT32, INT64, UINT64, INTN, UINTN }; type AnyType; type PointerType = AnyType *; idexpression ScalarType ScalarValue; idexpression PointerType PointerValue; constant SizeBase =~ "^(SIZE|BASE)_(1|2|4|8|16|32|64|128|256|512)[KMGTPE]B$"; constant NamedPowerOf2 =~ "^(EFI_PAGE_SIZE|CPU_STACK_ALIGNMENT|RUNTIME_PAGE_ALLOCATION_GRANULARITY)$"; constant ONE = {1, 1U, 1u}; @@ ( ( SizeBase | NamedPowerOf2 | ONE << E1 | sizeof (ScalarType) | sizeof (PointerType) | sizeof (ScalarValue) | sizeof (PointerValue) ) & PowOf2Expr ) @aligned depends on power_of_2_expr disable is_zero,isnt_zero@ expression E; expression power_of_2_expr.PowOf2Expr; constant ONE = {1, 1U, 1u}; constant ZERO = {0, 0U, 0u}; @@ ( ((E & (E - ONE)) == ZERO) | - ((E & ((PowOf2Expr) - ONE)) == ZERO) + IS_ALIGNED (E, PowOf2Expr) | ((E & (E - ONE)) != ZERO) | - ((E & ((PowOf2Expr) - ONE)) != ZERO) + !IS_ALIGNED (E, PowOf2Expr) | - ((E % (PowOf2Expr)) == ZERO) + IS_ALIGNED (E, PowOf2Expr) | - ((E % (PowOf2Expr)) != ZERO) + !IS_ALIGNED (E, PowOf2Expr) ) @address_is_aligned@ typedef UINTN; expression *Address; expression Alignment; @@ - IS_ALIGNED ((UINTN) Address, Alignment) + ADDRESS_IS_ALIGNED (Address, Alignment) @normalize_aligned disable paren expression@ expression E, SZ; @@ ( - (IS_ALIGNED (E, SZ)) + IS_ALIGNED (E, SZ) | - (!IS_ALIGNED (E, SZ)) + !IS_ALIGNED (E, SZ) ) @normalize_macro_args disable paren expression@ expression E, SZ; @@ ( - IS_ALIGNED ((E), SZ) + IS_ALIGNED (E, SZ) | - IS_ALIGNED (E, (SZ)) + IS_ALIGNED (E, SZ) ) ``` Signed-off-by: Mingjie Shen <shen497@purdue.edu>
