/* Justification for module-specific MISRA deviations:
MD_VStdLib_NoCaseBreak:
Reason: Break statements are omitted due to performance reasons when using jump tables.
Risk: Resulting code is misleading.
Prevention: Code comments, code inspection and test of the different variants in the component test.
MD_VStdLib_ParamMod:
Reason: Pointers and counts given as function parameters are modified during different algorithm stages.
Risk: Wrong pointer access is performed.
Prevention: Silent analysis, code inspection and test of the different variants in the component test.
MD_VStdLib_ParamValueMod:
Reason: The direct modification of the function parameter leads to code which is easier to read and maintain.
Risk: Incorrect expectation of the value of the modified function parameter.
Prevention: Code inspection and test of the different variants in the component test.
MD_VStdLib_PtrCast:
Reason: Pointer is casted as different memory access sizes are utilized due to performance reasons.
Risk: Wrong pointer access is performed.
Prevention: Code inspection and test of the different variants in the component test.
MD_VStdLib_PtrCastToInt:
Reason: Pointer is casted to an integral type in order to get the target alignment.
Risk: None, as only LSBs are evaluated.
Prevention: None.
MD_VStdLib_Para2ConstPtr
Reason: The address of a parameter is stored in a constant pointer in order to use the VStdLib_MemCpy().
Risk: None.
Prevention: None.
MD_VStdLib_NotUsedInUnit:
Reason: Static inline function is not used within this translation unit, because it is intended to be used as
a inline function by other modules.
Risk: None.
Prevention: None.
MD_VStdLib_FileScope:
Reason: Constant tables are kept at a central location for a better overview and maintenance.
Risk: None.
Prevention: None.
MD_VStdLib_Metrics:
Reason: No separation of functionality due to performance reasons when using jump tables.
Risk: None, as the complexity arises from one single switch statement.
Prevention: None.

**********************************************************************************************************************/
/* SBSW_JUSTIFICATION_BEGIN
\ID SBSW_VSTDLIB_CALL_UNMODIFIED
\DESCRIPTION A function is called with unmodified 'pDst' and 'nCnt' parameters.
\COUNTERMEASURE \N The caller of the function ensures that 'pDst' and 'nCnt' are valid. These parameters are passed
to the callee without modifications. If the parameters are casted there are no side effects.
\ID SBSW_VSTDLIB_CALL_MODIFIED_CNT
\DESCRIPTION A static function is called with unmodified 'pDst' parameter and a modified 'nCnt' parameter.
\COUNTERMEASURE \N The caller of the function ensures that 'pDst' and 'nCnt' are valid. The offset value is
always smaller than 4 due to VSTDLIB_ALIGN_OFFSET() and 'nCnt' is 32 or higher at this point.
Therefore 'pDst' and 'nCnt' for the callee are valid.
\ID SBSW_VSTDLIB_CALL_MODIFIED_IDX
\DESCRIPTION A static function is called with unmodified 'pDst' parameter starting at a specific offset and a modified
'nCnt' parameter.
\COUNTERMEASURE \N The caller of the function ensures that 'pDst' starting at offset and 'nCnt' are valid. The index
is always smaller equal to 'nCnt' bits starting at offset. Therefore 'pDst' starting at a
specific offset and 'nCnt' are valid for the callee.
\ID SBSW_VSTDLIB_CALL_CONVERTED_BITCNT
\DESCRIPTION A static function is called with unmodified 'pDst' parameter starting at a specific offset and a modified
'nCnt' parameter.
\COUNTERMEASURE \N The caller of the function ensures that 'pDst' and 'nCnt' are valid. 'nCntInBytes' is 'nCnt'
devided by 8. The devision by 8 converts the bit count in a valid byte count where the byte count
defines the same range as the bit count in a different format. Therefore 'pDst' starting at a
specific offset and 'nCnt' are valid for the callee.
\ID SBSW_VSTDLIB_CALL_CONVERTED_BITOFFSET
\DESCRIPTION A static function is called with unmodified 'pDst' starting at a specific offset and 'nCnt' parameters
but converted offset parameter(s).
\COUNTERMEASURE \N The caller of the function ensures that 'pDst' starting at offset is valid for 'nCnt' bits.
The conversion changes offset numbering from sawtooth to monotone or from monotone to sawtooth.
The change of the value of the offset from one numbering method to the other is 7 at most. The
offset is therfore still within the same byte. Thus the start byte and the end byte don't change
when converting bit counting numbering. Therefore 'pDst' starting at a specific offset and 'nCnt'
are valid for the callee.
\ID SBSW_VSTDLIB_CALL_MODIFIED_PTR_CNT
\DESCRIPTION A static function can be called with unmodified or modified 'pDst' and 'nCnt' parameters.
\COUNTERMEASURE \N The caller of the function ensures that 'pDst' and 'nCnt' are valid. In case the function is
called with modified parameters (pointer alignment was performed), 'pDst' is incremented by
the value of 'nDstOffset' and 'nCnt' is decremented by the same value. Therefore 'pDst'
and 'nCnt' for the callee are valid.
\ID SBSW_VSTDLIB_ACCESS_LOOP
\DESCRIPTION Linear memory access using a for loop.
\COUNTERMEASURE \N The caller of this function ensures that 'pDst' and 'nCnt' are valid. The for loop ensures that
the loop index is always smaller than nCnt. Therefore only valid memory is accessed.

statement ensures that an access is only made if at least 4 byte are valid. 'dPos' is
incremented by 4 after the access.
\ID SBSW_VSTDLIB_CALL_REMAINING_JUMPTABLE
\DESCRIPTION A static function is called to access the remaining bytes at the end of processing a 32-bit jump table.
\COUNTERMEASURE \N The caller of this function ensures that 'pDst' and 'nCnt' are valid. At this point 0-3
bytes of valid memory (indicated by the LSBs of 'remaining') start at the address that is
indicated by 'dPos'. Due to the usage of VSTDLIB_MASK_3 'pDst' and 'nCnt' for the callee are
valid.
\ID SBSW_VSTDLIB_CALL_REMAINING
\DESCRIPTION A static function is called to access the remaining bytes after 32-bit operations.
\COUNTERMEASURE \N The caller of this function ensures that 'pDst' and 'nCnt' are valid. After the for loop above
'remaining' bytes of valid memory start at the address that is indicated by 'dPos'. Therefore
'pDst' and 'nCnt' for the callee are valid.
