arch/arm32_code_inference

ARM32 architecture-specific rules for code inference.

arm_ver_order(Name:symbol, VersionID:unsigned)

Assign ARM version names to their generation number

e.g., “v7E_M” -> 7

• Used by: +disconnected8

init_ldr_add_pc(EA_ldr:address, Size:unsigned, Reg1:register, LitPoolAddr:address, EA_add_pc:address, Reg2:register)

ldr Reg1, .L0 add Reg2, Reg1, pc

Uses straight_line_def_used, which is a weaker version of def_used that can be used before code inference.

code_to_litpool_ref_point_transfer(Reason:symbol)

• Used by: block_heuristic

mode_min_instruction_size(Mode:unsigned, Size:unsigned)

Minimum instruction size for each execution mode.

Mode can be 0 (ARM) or 1 (Thumb)

• Used by: branch_to_calculated_pc_rel_addr

branch_to_calculated_pc_rel_addr(EA:address, Dest:address)

A computed PC-relative address that isn’t a jump table.

This example was generated in zlib with gcc 9.4. -Os:

adr r1, Label add r2, r1, r2, lsl #4 mov pc, r2

.Label:

cmp r3, r1, lsl #31 nop adc r0, r0, r0 it hs subhs r3, r3, r1, lsl #31

.Label+16:

cmp r3, r1, lsl #30 nop adc r0, r0, r0 it hs subhs r3, r3, r1, lsl #30

.Label+32:

…

In the above pattern, Label is supposed to be code rather than data (literal pools).
