ARM dialog box

Processor (drop-down list)

Generates code for the selected processor's instruction set. Equal to setting the corresponding -cpu flag on the command line.

Floating point processor (drop-down list)

Default

Generates code using the floating point capabilities of the selected processor.

None

Rejects any use of floating point variables or constants in C, C++, or Pascal. Equivalent to the -fnone build-time option.

Software

Generate software floating point emulation code, regardless of the capabilities of the selected processor. Libraries built for software will also be used. Equivalent to the -fsoft build-time option.

Fpal0

Generate code for the ARM Fpal0 hardware floating point unit. Equivalent to the :arm_fputype=fpa10 command line option.

The following is a description of the items in the ARM window:

Big endian

Generates code with big endian byte order. The most significant byte of an integer appears at the lowest address. Equivalent to the -bigendian command line option.

Thumb code

Generate code for 16-bit instruction Thumb mode. Equivalent to the -thumb command line option.

Thumb libraries

Link with runtime libraries built for Thumb mode (default is ARM libraries).
