◆ ConvertRegisterKindToRegisterNumber()

uint32_t RegisterContextMinidump_ARM::ConvertRegisterKindToRegisterNumber ( lldb::RegisterKind  kind,
uint32_t  num 

Convert from a given register numbering scheme to the lldb register numbering scheme.

There may be multiple ways to enumerate the registers for a given architecture. ABI references will specify one to be used with DWARF, the register numberings from process plugin, there may be a variation used for eh_frame unwind instructions (e.g. on Darwin), and so on. Register 5 by itself is meaningless - RegisterKind enumeration tells you what context that number should be translated as.

Inside lldb, register numbers are in the eRegisterKindLLDB scheme; arguments which take a register number should take one in that scheme.

eRegisterKindGeneric is a special numbering scheme which gives us constant values for the pc, frame register, stack register, etc., for use within lldb. They may not be defined for all architectures but it allows generic code to translate these common registers into the lldb numbering scheme.

This method translates a given register kind + register number into the eRegisterKindLLDB register numbering.

[in]kindThe register numbering scheme (RegisterKind) that the following register number is in.
[in]numA register number in the 'kind' register numbering scheme.
The equivalent register number in the eRegisterKindLLDB numbering scheme, if possible, else LLDB_INVALID_REGNUM.
