"`a', b, c, or d register for the i386. For x86-64 it is equivalent to `r'
class (for 8-bit instructions that
do not use upper halves). "

in online docs i see that "q" means "byte addressable register (a,b,c,d)".
in i386.h i see something differ for x86_64. did i miss something in docs?
#define REG_CLASS_FROM_LETTER(C)\
((C) == 'r'
