LONgreg, NOLONgreg: Register Allocation of 4-Byte Parameters
CPU [Pass 4-byte parameter/return value via register]
DOuble=Float: double to float Conversion
CPU [Treat double as float]
Remarks
If the CPU is H8/300 and the longreg is specified, up to 4 bytes of data can be allocated to a
register as a parameter and a return value.
Command Line Format
LONgreg
NOLONgreg
Description
Specifies whether 4-byte parameters or return values are allocated to registers or not.
The type of variable to be allocated to a register by this option is long, unsigned long, and
float.
If nolongreg is specified, parameters are passed via a memory instead of a register.
If longreg is specified, parameters can be passed via a register.
When this option is omitted, nolongreg is assumed.
Remarks
This option can be specified only when the CPU is H8/300.
When the CPU is not H8/300, 4-byte data can always be allocated to registers.
Command Line Format
DOuble=Float
Description
Generates an object after converting double-type (double-precision floating-point)
variables/values to float-type (single-precision floating-point) ones.
