Revisions for Using the Assembler

The following technical changes have been made to Using the Assembler.

Table 42. Differences between issue E and issue F
Change	Topics affected
Clarified the range of addresses accessible to the `ADR` instruction and the `ADRL` pseudo-instruction in ARM state.	Load addresses to a register using ADR Load addresses to a register using ADRL
Where appropriate: changed Thumb-2 to 32-bit Thumb changed Thumb-2EE to ThumbEE.	Various topics
Changed the minor version component of the built-in variable `ARMASM_VERSION` from one to two digits.	Built-in variables and constants

Table 43. Differences between issue C and issue D
Change	Topics affected
Added note about `--use_frame_pointer`.	General-purpose registers
Changed `ARMCC41` environment variables to `ARMCCnn`. And added link to the topic Toolchain environment variables in the Introducing the ARM Compiler toolchain document.	Specify command line options with an environment variable
Added topic on directives that can be omitted in pas 2. And added an Xref to this topic from How the assembler works.	Directives that can be omitted in pass 2 of the assembler
Added that all instructions must appear in both passes.	How the assembler works
Added ARM Glossary to other information.	Conventions and feedback

Table 44. Differences between issue B and issue C
Change	Topics affected
Added topic on 2 pass assembler diagnostics.	pass assembler diagnostics
Added topic on How the assembler works.	How the assembler works

Table 45. Differences between issue A and issue B
Change	Topics affected
Split the General-purpose registers topic into two. The second topic is called Register accesses.	General-purpose registers Register accesses
Added that PC is not considered as a general-purpose register and mentioned that the Assembler Reference describes when SP and PC can be used.	General-purpose registers
Mentioned that the use of PC in reglist in 32-bit Thumb instructions is for `LDM` and `POP` only.	Load and store multiple instructions available in ARM and Thumb
Added a note that ARM instructions are deprecated if reglist contains SP or PC (`STM` and `PUSH`), or both PC and LR (`LDM` and `POP`).	Load and store multiple instructions available in ARM and Thumb
Added a topic on Instruction and directive relocations.	Instruction and directive relocations
Added a topic on Thumb code size diagnostics.	Thumb code size diagnostics
Added a topic on ARM and Thumb instruction portability diagnostics.	ARM and Thumb instruction portability diagnostics
Added a link to Thumb code size diagnostics.	Instruction width selection in Thumb
Added that symbols beginning with $v must be avoided.	Symbol naming rules
Removed \| as an alias for :OR:	Addition, subtraction, and logical operators
Clarified that NEON is optionally available on ARMv7-A and ARMv7-R but not on ARMv7E-M. Clarified that ARMv7E-M adds only the VFP single-precision floating-point instructions.	Architecture support for NEON and VFP
Added a new topic on how to input assembly code using `stdin`.	Using stdin to input source code to the assembler
Added --execstack and --no_execstack to the Output group of command line options.	Assembler commands listed in groups
