Thanks John- I'll post this reply to both groups as a polite way of doing so then. :)
Most of our (my!) problems are with the different Linkage conventions under Linux of course. It uses a simple register based method to pass arguments to SVCs and C-Libraries functions, and yet it still uses a stack. More accurately, a stack frame. It does appear to be blazingly fast when written in assembler, even though handwritten assembler isn't using the pipelining tricks and such that are possible on zSeries hardware. (S/390 hardware.) And one of the issues we have to address is the current code runs in 24bit mode, but Linux only runs in 31 or 64 bit mode. I do not have any ideas what kind of weird and fascinating issues lie in our future based upon that... :) -Paul ----- Original Message ----- From: "John Ford" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Friday, April 04, 2003 12:08 AM Subject: Re: Linux/390 Assembler Guru's... > Paul, > > Ya.
