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' ? GENERAL_REGS : \
(C) == 'R' ? LEGACY_REGS : \
(C) == 'q' ? TARGET_64BIT ? GENERAL_REGS : Q_REGS : \
^^^^^^^^^^^^^^^^^^^^^^^^^^^
(C) == 'Q' ? Q_REGS : \
