分享资料个
This chapter gives a basic， practical understanding of how to write ARM and Thumb
assembly language modules. It also gives information on the facilities provided by the
ARM assembler （armasm）。
This chapter does not provide a detailed description of the ARM， Thumb， or VFP
instruction sets. This information can be found in Chapter 4 ARM Instruction
Reference， Chapter 5 Thumb Instruction Reference， and Chapter 6 Vector
Floating-point Programming. Further information can be found in ARM Architecture
Reference Manual.

There are a number of code examples in this chapter. Many of them are supplied in the
examples\asm directory of the ADS.
Follow these steps to build， link， and execute an assembly language file
1. Type armasm -g filename.s at the command prompt to assemble the file and
generate debug tables.
2. Type armlink filename.o -o filename to link the object file and generate an ELF
executable image.
3. Type armsd filename to load the image file into the debugger.
4. Type go at the armsd： prompt to execute it.
5. Type quit at the armsd： prompt to return to the command line.
To see how the assembler converts the source code， enter：
fromelf -text/c filename.o
or run the module in AXD with interleaving on.
