<div>This is both a question and an explanation<br>
of hopefully an uncoming chnage, if I figure it out.<br>
<br>
<br>
Most platforms are almost the same.<br>
<br>
For example I386_FREEBSD and I386_NETBSD.<br>
<br>
You want their IR to generally be the same, along<br>
as they aren't printing their actual target name.<br>
<br>
And they mostly are.<br>
<br>
Here is a difference for example:<br>

One line of the IR is moved.<br>
The meaning is the same (the IR is somewhat order-independent, e.g. for type declarations).<br>
<br>
What causes this?<br>
<br>
Do we output sometimes in hash order?<br>
And target affects that?<br>
<br>
Or when buffers fill up, and target length can affect that?<br>
<br>
I'd like to remove these differences.<br>
If it is a buffer length matter, I might just expand the buffers,<br>
as systems have far far more memory than when this was all written.<br>
<br>
<br>
If it is hash ordering matter -- one should avoid outputting data<br>
in hash order.<br>
<br>
so:<br>
1. if anyone knows the difference, please tell me, before I debug it?<br>
2. Ok if I make changes to converge the IR, i.e. I386_LINUX/Darwin/Solaris/FreeBSD/NetBSD/OpenBSD/Interix should all<br>
be the same, AMD64/ditto, SPARC32/ditto, SPARC64/ditto. Only variation should be endian and word size,<br>
and maybe NT vs. Posix but probably not.<br>
