Well, I think so:
enum reg_class
{
NO_REGS,
BP_REGS,
STACK_REGS,
EIGHT_REGS,
EVEN_REGS,
GENERAL_REGS,
ALL_REGS,
LIM_REG_CLASSES
};
#define N_REG_CLASSES ((int) LIM_REG_CLASSES)
#define REG_CLASS_CONTENTS \
{ \
{ 0x00000000 }, \
{ 0x00000001 }, \
{ 0x80000000 }, \
{ 0x000000FF }, \
{ 0x55555555 }, \
{ 0x7FFFFFFE }, \
{ (1LL << FIRST_PSEUDO_REGISTER) - 1 } \
}
...
(define_register_constraint "z" "EVEN_REGS"
"Even registers (r0,r2,r4, @dots{} r30)")
