And on SLES10 this works indeed: # cat epsw.s .globl main main: epsw %r2,%r3 svc 1 # exit system call. return value in r2 # gcc epsw.s # ./a.out ; echo $? 1 By the way, if you are just interested in the condition code, then IPM + SRL is faster.

The relevant line from the binutils opcode description file b98d epsw RRE_RR "extract psw" z900 esa,zarch That instruction exists for esa and zarch mode starting with the z900. A -march=z900 should enable the instruction if your binutils version is recent enough. With older binutils version you can use the ".insn" pseudo-op: .insn rre,0xb98d0000,%r<x>,%r<y> -- blue skies, Martin.

When I mean new I mean more recent than > s/370 :-) EPSW was new with z/Architecture, and was also added to the ESA/390 instruction set on z/Architecture machines. Compilation for a z900 or later will provide what you need. QED. Those creepy tables in Appendix B of the Principles of Operation provide this information, once you intuit that "New in z/Architecture" (N, N3) is "z900". The presence of instructions added after that point are indicated by a facilities bit from STFL/STFLE.

How to get them working and, especially, how to get them to perform well are of major concern. However, since this is all still relatively new, there isn't a lot of information or real life experience available yet. Because of the growing interest in this area, the "Linux and VM Program" of SHARE has put together a series of presentations dedicated to this subject. These presentations will feature people with real life experience in porting Oracle applications to zLinux, such as Gerard Shockley of Boston University and David Lacey of Aetna, as well as experts who have supported numerous customers during their transitions to this environment. This series will feature up-to-date information on new releases, hidden hazards as well as hints and tips to make everything work well. If you are running or are about to port Oracle based applications to zLinux, you cannot afford to miss these presentations. This series will take place on Wed, Aug. 4 in Boston, MA as part of the overall SHARE conference. (For a specific listing of the presentations being offered, please see http://share.org ) There is still plenty of time to register for SHARE. Full week and single day registrations are available.
