This is currently intended to handle cases where a program stops at an instruction that won't get executed and it allows the stop reason, like "breakpoint hit", to be replaced with a different stop reason like "no stop reason". | |
lldb::addr_t | GetCallableLoadAddress (lldb::addr_t load_addr, AddressClass addr_class) const override |
Get load_addr as a callable code load address for this target. | |
lldb::addr_t | GetOpcodeLoadAddress (lldb::addr_t load_addr, AddressClass addr_class) const override |
Get load_addr as an opcode for this target. | |

Get load_addr as a callable code load address for this target.
Take load_addr and potentially add any address bits that are needed to make the address callable. For ARM this can set bit zero (if it already isn't) if load_addr is a thumb function. If addr_class is set to AddressClass::eInvalid, then the address adjustment will always happen. If it is set to an address class that doesn't have code in it, LLDB_INVALID_ADDRESS will be returned.

Get load_addr as an opcode for this target.
Take load_addr and potentially strip any address bits that are needed to make the address point to an opcode. For ARM this can clear bit zero (if it already isn't) if load_addr is a thumb function and load_addr is in code. If addr_class is set to AddressClass::eInvalid, then the address adjustment will always happen. If it is set to an address class that doesn't have code in it, LLDB_INVALID_ADDRESS will be returned.

This is currently intended to handle cases where a program stops at an instruction that won't get executed and it allows the stop reason, like "breakpoint hit", to be replaced with a different stop reason like "no stop reason".
This is specifically used for ARM in Thumb code when we stop in an IT instruction (if/then/else) where the instruction won't get executed and therefore it wouldn't be correct to show the program stopped at the current PC. The code is generic and applies to all ARM CPUs.
