PTr16: Pointer Size Specification
C/C++ <Optimize>[2byte pointer]
ABS8, ABS16: Short Absolute Addressing Mode
C/C++ <Optimize>[Data access :]
32
Command Line Format
PTr16
Description
Sets the size of the pointer indicating data to two bytes.
Remarks
If this option is not specified, the size of the pointer indicating data is four bytes. If this option
is specified, the data section to be referenced must be explicitly located in the 16-bit absolute
address area. Addresses where to locate sections are specified with the start option of the
optimizing linkage editor. For details on the start option, refer to section 4.2.5, Section
Options. For details on the 16-bit absolute address area, refer to section 19.3, Access Range of
Short Absolute Addresses.
This option is valid only if the CPU/operating mode is H8SXA, H8SXX, H8S/2600A, or
H8S/2000A.
Take care the use of the ptr16 option so that the handling of the same data and caller-callee
relationship of the same function are consistent among files because changing the size of the
pointer-to-data from 4 to 2 affects not only the resource allocation, but also the method to pass
a function parameter and the function return value.
Command Line Format
ABS8
ABS16
Description
Accesses the data to be allocated to the static area in short absolute addressing mode.
When abs8 is specified, the compiler generates codes in 8-bit absolute addressing mode
(@aa:8) for accessing char, unsigned char, and composite data, which is 1-byte aligned,
consisting of char or unsigned char elements or members.
When abs16 is specified, the compiler generates codes for accessing data in 16-bit absolute
addressing mode (@aa:16) for the CPU/operating mode of H8SXA, H8SXX, 2600a, 2000a,
and 300ha. For the CPU/operating mode of H8SXN, H8SXM, 2600n, 2000n, 300hn, and 300,
abs16 is invalid.
The data to be accessed in 8-bit absolute addressing (abs8 option) is output to section name
“$ABS8C”, “$ABS8D”, or “$ABS8B”. The data to be accessed in 16-bit absolute addressing
mode (abs16 option) is output to section name “$ABS16C”, “$ABS16D”, or “$ABS16B”.
