The following documentation discusses the options for the assembler for the NEC VR4300 family of processors.
MIPS-specific command-line options
For a list of available generic assembler options, refer to Command-Line Options in Using AS in GNUPro Utilities.
-EB
-EL
Any
MIPS configuration of the assembler can select big-endian or little-endian
output at run time.
Use ‘-EB’ to select big-endian output, and ‘-EL’ for little-endian. The default is big-endian.
For information about the MIPS instruction set, see MIPS RISC Architecture, (Kane and Heindrich, Prentice-Hall). For an overview of MIPS assembly conventions, see “Appendix D: Assembly Language Programming” in the same volume.
There are 32 64-bit general (integer) registers, named ‘$0..$31’. There are 32 64-bit floating point registers, named ‘$f0..$f31’.
