+// e32test\buffer\t_func.cpp
+// Overview:
+// Comprehensive test for the ARM coded Mem, Des and integer divide routines.
+// Check memory for a large variation of buffer sizes and alignments,
+// check all the optimizations made in the copying/filling code.
+// API Information:
+// Mem::Fill, Mem::Copy, Mem::Move, Mem::Swap, Mem::Compare
+// Details:
+// - Create blocks, fill some data into one block, copy data across block of varying
+// lengths, alignments and check the copy is as expected.
+// - Create blocks, fill some data into the block, move data from one block to other
+// block and check it is as expected.
+// - Create blocks, fill some data and check the data is filled as expected.
+// - Create blocks, fill some data in two blocks, swap the blocks check the data
+// is swapped as expected.
+// - Create blocks, fill some data into the blocks, compare the data at different specified
+// offsets, compare the return value, check it is as expected.
+// - Check the conversion from specified integer numbers in different number systems to
+// character representation is as expected. Check for both upper and lower case results.
+// - Initialize variables with signed, unsigned, positive, negative integer values, check the
+// integer division routines are as expected.
+// - Check the integer modulo operation results are as expected.
+// Platforms/Drives/Compatibility:
+// All
+// Assumptions/Requirement/Pre-requisites:
+// Failures and causes:
+// Base Port information:
