--- Comment #1 from Luke Kenneth Casson Leighton <lkcl at lkcl.net> ---

lkcl    octavius, the language of the RFC needs to be more "x is added to y and
placed into z"  20:12
lkcl    the wording of maddld (etc) can be used as a template   20:12
lkcl    btw we need a bugreport for it  20:13
lkcl    https://bugs.libre-soc.org/show_bug.cgi?id=944 is for ls002     20:13
lkcl    so, maddhd says:        20:14
lkcl    "The 64-bit operands are (RA), (RB), and (RC). The      20:14
lkcl    128-bit product of the operands (RA) and (RB) is        20:14
lkcl    added to (RC). The high-order 64 bits of the 128-bit    20:14
lkcl    sum are placed into register RT.        20:14
lkcl    "       20:14
lkcl    therefore, we literally cut-and-paste that text 20:14
lkcl    and     20:14
lkcl    add     20:14
lkcl    "The low-order 64-bits of the 128-bit sum are placed into register RC" 
lkcl    also, you removed the tag       20:17
lkcl    which ensures that ls003 is missing from this auto-generated page:
