[Zlib-devel] Re: AMD64 and inffas86.c

[Gilles Vollant]

I've just a question :
My application made several push at begin and pop at end.

see http://weblogs.asp.net/oldnewthing/archive/2004/01/14/58579.aspx
"All registers must be preserved across the call, except for rax, rcx, rdx,
r8, r9, r10, and r11, which are scratch."

Pehaps this is not the faster way to save register

I used this script to convert from gcc to msvc in inffas86.c.  First I
clipped out the lines in __asm__ __volatile__ (lines 463 to 783), then ran
gcc2masm.pl < lines463-783.txt > masm.out.  I believe that converts most or
all of the 32 bit instructions but doesn't do the 64 bit ones. 
I'll look at that tomorrow morning...
