 \item only on hard-float targets: if the very first call argument is a float, up to 2 floats or doubles can be passed via \$f12 and \$f14, respectively, for first and second argument
 \item only on hard-float targets: if any arguments are passed via float registers, skip \$a0-\$a3 for subsequent arguments as if the values were passed via them
 \item only on hard-float targets: note that if the first argument is not a float, but the second, it'll get passed via the \$a? registers
-\item results are returned in \$v0 and \$v1, with \$v0 for all values < 64bit (only integer, on hard-float targets)
+\item results are returned in \$v0 and \$v1, with \$v0 for all values < 64bit (only integer on hard-float targets)
 \item only on hard-float targets: floating point results are returned in \$f0 (32-bit float), or \$f0 and \$f3 (64bit float)
+\item single precision float parameters (32 bit) are right-justified in their 8-byte slot on the stack on big endian targets, as they aren't promoted @@@
