Thumb Instruction Set Encoding If the destination register specifier of an LDRB, LDRH, LDRSB, or LDRSH instruction is 0b1111, the instruction is a memory hint instead of a load operation. If the destination register specifier of an MRC instruction is 0b1111, bits [31:28] of the value transferred from the coprocessor are written to the N, Z, C, and V flags in the APSR, and bits [27:0] are discarded. A6.1.3 Use of 0b1101 as a register specifier R13 is defined in the Thumb instruction set so that its use is primarily as a stack pointer, and R13 is normally identified as SP in Thumb instructions. In 32-bit Thumb instructions, if you use R13 as a general-purpose register beyond the architecturally defined constraints described in this section, the results are UNPREDICTABLE. The restrictions applicable to R13 are described in: R13[1:0] definition 32-bit Thumb instruction support for R13. See also 16-bit Thumb instruction support for R13 on page A6-5. R13[1:0] definition Bits [1:0] of R13 are SBZP. Writing a nonzero value to bits [1:0] causes UNPREDICTABLE behavior. 32-bit Thumb instruction support for R13 R13 instruction support is restricted to the following: R13 as the source or destination register of a MOV instruction. Only register to register transfers without shifts are supported, with no flag setting: MOV SP, MOV ,SP Using the following instructions to adjust R13 up or down by a multiple of 4: ADD{W} SP,SP,# SUB{W} SP,SP,# ADD SP,SP, ADD SP,SP,,LSL # ; For = 1,2,3 SUB SP,SP, SUB SP,SP,,LSL # ; For = 1,2,3 R13 as a base register of any load/store instruction. This supports SP-based addressing for load, store, or memory hint instructions, with positive or negative offsets, with and without writeback. R13 as the first operand in any ADD{S}, CMN, CMP, or SUB{S} instruction. The add and subtract instructions support SP-based address generation, with the address going into a general-purpose register. CMN and CMP are useful for stack checking in some circumstances. R13 as the transferred register in any LDR or STR instruction. A6-4 Copyright © 1996-1998, 2000, 2004-2008 ARM Limited.

16-bit Thumb instruction support for R13 Thumb Instruction Set Encoding For 16-bit data-processing instructions that affect high registers, R13 can only be used as described in 32-bit Thumb instruction support for R13 on page A6-4. Any other use is deprecated. This affects the high register forms of CMP and ADD, where the use of R13 as is deprecated. ARM DDI 0406B Copyright © 1996-1998, 2000, 2004-2008 ARM Limited.
