Hi Jian,

It occurs to me that we might be able to achieve something like this,
if we extend the macro argument syntax to include a definition of the
argument separator. For example:
.macro foo insn1:sep, insn2:vararg
\insn1
\insn2
.endm
This would tell the macro processor that insn1 takes all characters up to
(but excluding) the next comma character and that insn2 takes the rest of
the line (starting at the first non-whitespace character after the comma).
The new syntax "<arg>:sep<char>" tells the macro processor that argument
<arg> is separated from the next argument by the <char> character, and only
by the <char> character, so that any other character (apart from line ending
characters) forms part of <arg>.
This syntax does not exist *yet*. I am going to have a look at implementing
it, but if it is too difficult I will give up.
What do you think - would this change provide the functionality that you
desire ?
Cheers
Nick
