regformats/regdat.sh generate some *-generated.c files when GDBserver
is built. Each .c file has some static variables, which are only used
within function init_registers_XXX, like this,
static struct reg regs_i386_linux[] = {
{ "eax", 0, 32 },
{ "ecx", 32, 32 },
...
};
static const char *expedite_regs_i386_linux[] = { "ebp", "esp", "eip", 0 };
static const char *xmltarget_i386_linux = "i386-linux.xml";
void
init_registers_i386_linux (void)
{
...
}
This patch moves these static variables' definitions to function
init_registers_XXX, so the generated files look like this,
void
init_registers_i386_linux (void)
{
static struct target_desc tdesc_i386_linux_s;
struct target_desc *result = &tdesc_i386_linux_s;
static struct reg regs_i386_linux[] = {
...
};
static const char *expedite_regs_i386_linux[] = { "ebp", "esp", "eip", 0 };
static const char *xmltarget_i386_linux = "i386-linux.xml";
...
}

* regformats/regdat.sh: Adjust code order.
