class Registers
Defined at line 135 of file ../../src/lib/unwinder/registers.h
Holds the register values. It's possible to get and set a register id that is not listed above.
Public Methods
fit::result<Error, Registers> To32Bit ()Converts the current register object to the equivalent 32 bit register set. This means that
all general purpose registers are copied wholesale (without checking if the value can actually
fit in a 32 bit register), and the specially named registers are copied using the getters and
setters below.

Error GetReturnAddress (uint64_t & ra)These are not formally specified for all architectures, but we define aliases for them.
It's RIP on x64, LR on Arm64, R14 on Arm, and RA on Riscv64. See the note above for why this
doesn't necessarily always make sense for x64.
