Target hardware levels
IBM® Automatic Binary Optimizer for z/OS® can generate program modules for the latest IBM Z servers.
Automatic Binary Optimizer for z/OS uses the same hardware numbering scheme as the COBOL compilers. Table 1 lists the hardware levels that are supported by IBM Automatic Binary Optimizer for z/OS Version 2.1. You can use the ARCH option to specify which hardware level you want the ABO produced modules to target.
Hardware level | Description |
---|---|
10 | Generates code that uses instructions available
on the 2827-xxxx (IBM zEnterprise® EC12) and 2828-xxxx
(IBM zEnterprise BC12) models in z/Architecture® mode. Specifically,
these level 10 machines and their follow-ons add instructions with
support of the following facilities:
|
11 | Generates code that uses instructions available on the
2964-xxxx (IBM z13®) and 2965-xxx (IBM
z13s®) models in z/Architecture mode. Specifically, these level 11 machines and their follow-ons add
instructions with support of the following facilities:
|
12 | Generates code that uses instructions available on 3906-xxx (IBM z14) and 3907-xxx (IBM z14 ZR1) models in z/Architecture mode. Specifically, these level 12 machines and their follow-ons add instructions that support the vector packed-decimal facility, which accelerates packed-decimal computation by storing intermediate results in vector registers instead of in memory. |
13 | Generates code that uses instructions available on 8561-xxx (IBM z15) and 8562-xxx (IBM z15 T02) models in z/Architecture mode. Specifically, these level 13
machines and their follow-ons add instructions supported by the following facilities:
