* Makefile.am (i386-gen.o): Also depend on
'J' => print 'l'
'K' => print 'd' or 'q' if rex prefix is present.
'L' => print 'l' if suffix_always is true
+ 'M' => print 'r' if intel_mnemonic is false.
'N' => print 'n' if instruction has no wait "prefix"
'O' => print 'd' or 'o' (or 'q' in Intel mode)
'P' => print 'w', 'l' or 'q' if instruction has an operand size prefix,
'Y' => 'q' if instruction has an REX 64bit overwrite prefix and
suffix_always is true.
'Z' => print 'q' in 64bit mode and behave as 'L' otherwise
+ '!' => change condition from true to false or from false to true.
Many of the above letters print nothing in Intel mode. See "putop"
for the details.
