Compiler Command-line Options Table 2-2 Supported ARM architectures (continued) Architecture Description 6 ARMv6 with Thumb, interworking, DSP multiply, double-word instructions, unaligned and mixed-endian support, Jazelle, and media extensions 6-M ARMv6 micro-controller profile with Thumb only plus processor state instructions 6K 6S-M 6T2 6Z ARMv6 with SMP extensions ARMv6 micro-controller profile with Thumb only, plus processor state instructions and OS extensions ARMv6 with Thumb-2 ARMv6 with Security Extensions 7 ARMv7 with Thumb-2 only and without hardware divide b 7-A ARMv7 application profile supporting virtual MMU-based memory systems, with ARM, Thumb, Thumb-2, and Thumb-2EE instruction sets, DSP support, and 32-bit SIMD support 7-R ARMv7 real-time profile with ARM, Thumb, Thumb-2, DSP support, and 32-bit SIMD support 7-M ARMv7 micro-controller profile with Thumb-2 only and hardware divide a. The ARM compiler cannot generate Java bytecodes. b. ARM v7 is not a recognized ARM architecture. Rather, it is the common subset of architectures ARMv7-A, ARMv7-R and ARMv7-M. Default If you do not specify a --cpu option, the compiler assumes --cpu=ARM7TDMI. To get a full list of CPU architectures and processors, use the --cpu=list option. Usage The following general points apply to processor and architecture options: Processors • Selecting the processor selects the appropriate architecture, Floating-Point Unit (FPU), and memory organization. 2-16 Copyright © 2007, 2010 ARM Limited.

Compiler Command-line Options • The supported --cpu values include all current ARM product names or architecture versions. Other ARM architecture-based processors, such as the Marvell Feroceon and the Intel XScale, are also supported. • If you specify a processor for the --cpu option, the compiled code is optimized for that processor. This enables the compiler to use specific coprocessors or instruction scheduling for optimum performance. Architectures • If you specify an architecture name for the --cpu option, the code is compiled to run on any processor supporting that architecture. For example, --cpu=5TE produces code that can be used by the ARM926EJ-S ® . FPU • Some specifications of --cpu imply an --fpu selection. For example, when compiling with the --arm option, --cpu=ARM1136JF-S implies --fpu=vfpv2. Note Any explicit FPU, set with --fpu on the command line, overrides an implicit FPU. • If no --fpu option is specified and no --cpu option is specified, --fpu=softvfp is used. • If an architecture v7 processor with an FPU is selected, the default FPU type is --fpu=vfpv3. ARM/Thumb • Specifying a processor or architecture that supports Thumb instructions, such as --cpu=ARM7TDMI, does not make the compiler generate Thumb code. It only enables features of the processor to be used, such as long multiply. Use the --thumb option to generate Thumb code. Note Specifying the target processor or architecture might make the object code generated by the compiler incompatible with other ARM processors. For example, code compiled for architecture ARMv6 might not run on an ARM920T processor, if the compiled ARM DUI 0348A Copyright © 2007, 2010 ARM Limited. All rights reserved. 2-17 Non-Confidential
