IBM Z Software


This portal is to open public enhancement requests against IBM Z Software products. To view all of your ideas submitted to IBM, create and manage groups of Ideas, or create an idea explicitly set to be either visible by all (public) or visible only to you and IBM (private), use the IBM Unified Ideas Portal (https://ideas.ibm.com).


Shape the future of IBM!

We invite you to shape the future of IBM, including product roadmaps, by submitting ideas that matter to you the most. Here's how it works:

Search existing ideas

Start by searching and reviewing ideas and requests to enhance a product or service. Take a look at ideas others have posted, and add a comment, vote, or subscribe to updates on them if they matter to you. If you can't find what you are looking for,

Post your ideas

  1. Post an idea.

  2. Get feedback from the IBM team and other customers to refine your idea.

  3. Follow the idea through the IBM Ideas process.

Metal C - Compiler option to specify a register to map DSA

Currently Metal C uses Register 13 to map the DSA. Pls add a compiler option, for the user to specify the register that the compiler should use to map the DSA. Register 13 contents usually point to the save area. We have use cases, where the save ...

Need more builtin functions in C/C++ compiler

In the XL C/C++ Programming Guide there are only a few General instructions like __pack and __unpack.In order for Metal C to be used for system software it would be better if these instructions were expanded so __asm would not have to be used as o...

Provide I18N/L10N gettext APIs for XL/C on z/OS

A system level, common, industry standard, platform independent, service is needed to perform internationalization/localization translation services on text strings when running on z/OS. This is needed for both applications compiled to use Languag...

Inline __asm() to communicate ARCHLVL to HLASM for system macros

When a z/OS system macro is embedded in a __asm() block, HLASM assumes ARCHLVL=1 which means the macro will use base+displacement branching, which fails in an inline __asm() block due to "no active USING". Most macros implement a MF=E form which g...

Allow -qlistfmt=html=inlines to break down the report into multiple files

Allow the reporting tools to generate multiple report files depending on the size limit provided by the client.

Enhance constant propagation

The optimizer should take advantage of constantness of variables and propagate their values into generated instructions.

Enhance compiler optimizer

The compiler should generate more efficient code for testing bitfields when the bits tested are located in the same byte.

inline ASM DS incorrect load for long long

With inline ASM to initialize a long long variable using an ASM DS instruction in 31-bit mode, the compiler is only generating an 'L' instruction, which does not load the full 64-bit register representing the long long variable: unsigned long long...

Insufficient inlining for function pointers

The compiler is currently unable to inline a function that is passed to another function as a function pointer parameter. As a result trivial functions may not be inlined when called using a function pointers.
