+ < zyg> did the segment registers had any purpose? I see fs is set equal to
+ others, but on linux fs is 0 (atleast on this x86 box).
+ < braunr> zyg: it can be used by special applications like wine, yes
+ < zyg> braunr: thanks.. I'm reading up on linux actually. It seems gs can
+ be used for TLS, fs in syscall to pass userspace.
+ < braunr> zyg: why are you interested in that ?
+ < zyg> a native compiler under linux places assumptions on fs register. So
+ I'm trying to find out what it should do under gnumach/hurd.
+ < braunr> what compiler ?
+ < zyg> braunr: it's sbcl
+ < braunr> ok
+ < youpi> zyg: the same, basically
+ < zyg> ok.. looking at the code, I've remarked where it sets up FS, because
+ /usr/include/asm/ldt.h:struct user_desc is missing. I must search for the
+ equiv.
+ < youpi> zyg: mach/i386/mach_i386.h
+ < youpi> the descriptor structure
