what does this arm instruction means?
LDRB param_1,[r12,r5]=>local_b0
In particular I don't understand the "=>local_b0" part.
Ghidra decompiles it to
local_b0._0_1_ = *(byte *)((int)&local_b0 + iVar1);
but I don't know where the ".0_1" comes from.
Thanks!
Seems like you've already figured this out, but this is a Ghidra markup. It can be enabled/disabled via Edit -> Tool Options -> Listing Fields -> Operands Field -> Always Show Primary Reference Here's what the help says about the option:
Always Show Primary Reference - Option to force the display of the primary reference on all operands. If a suitable sub-operand replacement can not be identified the primary reference will be appended to the operand preceded by a "=>" prefix.
