ARM VERSION 1.2 manual First pass and reads them from memory on the second pass, As \n and \t

Assembler Reference

-nocache	turns off source caching. By default the assembler caches source files on
	the first pass and reads them from memory on the second pass.
-noesc	instructs the assembler to ignore C-style escaped special characters, such
	as \n and \t.
-noregs	instructs the assembler not to predefine register names. See Predefined
	register and coprocessor names on page 3-9 for a list of predefined
	register names.
-nowarn	turns off warning messages.
-ofilename	names the output object file. If this option is not specified, the assembler
	uses the second command-line argument that is not a valid command-line
	option as the name of the output file. If there is no such argument, the
	assembler creates an object filename of the form inputfilename.o.

-predefine "directive"

instructs the assembler to pre-execute one of the SET directives. You must enclose directive in quotes. See SETA, SETL, and SETS on page 7-7.

The assembler executes a corresponding GBLL, GBLS, or GBLA directive to define the variable before setting its value.

The variable name is case-sensitive.

Note

The command line interface of your system might require you to enter special character combinations, such as \”, to include strings in directive. Alternatively, you can use -viafile to include a -predefineargument. The command line interface does not alter arguments from -viafiles.

-split_ldmThis option instructs the assembler to fault LDM and STM instructions if the maximum number of registers transferred exceeds:

•five, for all STMs, and for LDMs that do not load the PC

•four, for LDMs that load the PC.

Avoiding large multiple register transfers can reduce interrupt latency on

ARM systems that:

•do not have a cache or a write buffer (for example, a cacheless ARM7TDMI)

•use zero wait-state, 32-bit memory.
