WitrynaSince 32-bit constants cannot be encoded in 32-bit opcodes (or 16-bit for Thumb instructions), the assembler stores the constant in the text segment close to the referencing instruction and then references the value using (usually) PC-relative addressing, i.e. some offset from r15. Thus, ldr is in fact a pseudo instruction. The … WitrynaLoad and store instructions with immediate offset can use the following addressing modes: Offset addressing The offset value is added to or subtracted from the address obtained from the register Rn . WitrynaThere is no base register. foo and -0x10 are both part of the displacement, both link-time constants. foo is a symbol address that the linker will fill in and subtract 0x10 from (because of the -0x10 assemble-time offset). If you have the choice, use just a base instead of an index with a scale of 1. fitness schedule planner
