Using the Inline and Embedded Assemblers of the ARM Compiler
7.23 Inline assembler intermediate operands in C and C++ code
A C or C++ constant expression of an integral type might be used as an immediate value in an
inline assembly language instruction.
A constant expression that is used to specify an immediate shift must have a value that lies in
the range defined in the ARM Architecture Reference Manual, as appropriate for the shift
operation.
A constant expression that is used to specify an immediate offset for a memory or coprocessor
data transfer instruction must have a value with suitable alignment.
