Please note that this patch is maily for feedback collection and the only the MdeModulePkg part of the series is sent out firstly.
For pointer subtraction, the result is of type "ptrdiff_t". According to the C11 spec, ptrdiff_t is a signed integer type but its size is implementation-defined. There are cases that the result of pointer subtraction is type casted to UINTN, like: UINT8 *Ptr1, *Ptr2; UINTN PtrDiff; ... PtrDiff = (UINTN) (Ptr1 - Ptr2); Some static code checkers may warn that the pointer subtraction might overflow first and then the result is being cast to a bigger size. The series will cast each pointer to UINTN first and then perform the subtraction: PtrDiff = (UINTN) Ptr1 - (UINTN) Ptr2; Hao Wu (6): MdeModulePkg: Refine type cast for pointer subtraction CryptoPkg: Refine type cast for pointer subtraction IntelFrameworkModulePkg: Refine type cast for pointer subtraction NetworkPkg: Refine type cast for pointer subtraction SecurityPkg: Refine type cast for pointer subtraction ShellPkg: Refine type cast for pointer subtraction .../BaseCryptLib/SysCall/RuntimeMemAllocation.c | 6 +++--- IntelFrameworkModulePkg/Csm/LegacyBiosDxe/LegacyPci.c | 4 ++-- .../Library/GenericBdsLib/BdsBoot.c | 4 ++-- .../Library/GenericBdsLib/BdsConsole.c | 4 ++-- .../Library/GenericBdsLib/BdsMisc.c | 4 ++-- .../Library/LegacyBootManagerLib/LegacyBm.c | 4 ++-- .../Universal/BdsDxe/BootMaint/BootOption.c | 6 +++--- MdeModulePkg/Bus/Pci/PciBusDxe/PciOptionRomSupport.c | 4 ++-- MdeModulePkg/Include/Library/NetLib.h | 6 +++--- MdeModulePkg/Library/DxeCapsuleLibFmp/DxeCapsuleLib.c | 4 ++-- .../Library/DxePrintLibPrint2Protocol/PrintLib.c | 2 +- MdeModulePkg/Library/FileExplorerLib/FileExplorer.c | 6 +++--- .../Library/PiDxeS3BootScriptLib/BootScriptSave.c | 4 ++-- MdeModulePkg/Library/UefiBootManagerLib/BmLoadOption.c | 4 ++-- MdeModulePkg/Universal/DebugPortDxe/DebugPort.c | 4 ++-- .../FaultTolerantWriteDxe/FaultTolerantWrite.c | 4 ++-- MdeModulePkg/Universal/HiiDatabaseDxe/Image.c | 4 ++-- MdeModulePkg/Universal/Variable/RuntimeDxe/Variable.c | 10 +++++----- NetworkPkg/HttpDxe/HttpImpl.c | 6 +++--- .../DxeImageVerificationLib/DxeImageVerificationLib.c | 18 +++++++++--------- .../DxeTpmMeasureBootLib/DxeTpmMeasureBootLib.c | 10 +++++----- SecurityPkg/Library/Tpm2CommandLib/Tpm2Help.c | 6 +++--- SecurityPkg/Tcg/Tcg2Dxe/MeasureBootPeCoff.c | 10 +++++----- SecurityPkg/Tcg/TrEEDxe/MeasureBootPeCoff.c | 10 +++++----- .../SecureBootConfigDxe/SecureBootConfigImpl.c | 14 +++++++------- ShellPkg/Application/Shell/ShellParametersProtocol.c | 6 +++--- ShellPkg/Library/UefiShellDebug1CommandsLib/DmpStore.c | 4 ++-- .../UefiShellDebug1CommandsLib/SmbiosView/SmbiosView.c | 4 ++-- ShellPkg/Library/UefiShellDriver1CommandsLib/Dh.c | 4 ++-- ShellPkg/Library/UefiShellLevel2CommandsLib/Cd.c | 6 +++--- 30 files changed, 91 insertions(+), 91 deletions(-) -- 1.9.5.msysgit.0 _______________________________________________ edk2-devel mailing list edk2-devel@lists.01.org https://lists.01.org/mailman/listinfo/edk2-devel
