code_to_litpool_ref_point_transfer(Reason:symbol)

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).
