CPUExpand, NOCPUExpand: Operation Size Expanded Interpretation
C/C++ <Object>[Mul/Div operation specification]
16
The string literal output to the initialized data area can be modified during program execution;
however, the initialized data area must be allocated in both ROM and RAM in order to transfer
the string literal to RAM from ROM at the beginning of program execution. For details on the
initial settings of the initialized data area or on memory allocation, refer to section 9.2.1
Memory Allocation.
When this option is not specified, the compiler assumes that string=const is specified.
Command Line Format
CPUExpand [=V6]
NOCPUExpand
Description
cpuexpand generates multiplication and division code for variables by deviating from the
ANSI C-language standard.
Specifying cpuexpand=v6 makes Ver.6.0 cpuexpand specification when output code is
generated by Ver.4.0 optimization technology.
With this sub-option, generated codes are affected by the following C-source descriptions.
(a)
(b) signed long = unsigned int << Constant
(c)
(d) unsigned long = unsigned int << Constant
(e)
(f)
(g) signed int = (unsigned int << Constant) / unsigned int
(h) unsigned int = (signed int << Constant) / signed int
(i)
(j)
When nocpuexpand is specified, the compiler generates multiplication and division code
conforming to the ANSI C-language standard.
When this option is not specified, the compiler assumes that nocpuexpand is specified.
Remarks
When cpuexpand and cpuexpand=V6 is specified, the operation specifications exceed the
range guaranteed by the C language specifications, and the result may be different from that
obtained when nocpuexpand is specified.
Table 2.3 shows examples of multiplication and division code generated by specifying this
option.
signed long = signed int << Constant
unsigned long = signed int << Constant
signed int = (signed int << Constant) / signed int
signed int = (unsigned int << Constant) / signed int
unsigned int = (unsigned int << Constant) / signed int
unsigned int = (unsigned int << Constant) / unsigned int
