/* The following bits of code help with implementing debugging 32-bit
|
|
|
|
code natively on AMD64. The idea is to define two mappings between
|
|
|
|
the register number as used by GDB and the register set used by the
|
|
|
|
host to represent the general-purpose registers; one for 32-bit
|
|
|
|
code and one for 64-bit code. The mappings are specified by the
|
|
|
|
follwing variables and consist of an array of offsets within the
|
|
|
|
register set indexed by register number, and the number of
|
|
|
|
registers supported by the mapping. We don't need mappings for the
|
|
|
|
floating-point and SSE registers, since the difference between
|
|
|
|
64-bit and 32-bit variants are negligable. The difference in the
|
|
|
|
number of SSE registers is already handled by the target code. */
