redefining functions in header files - do it the right way

When functions in header files need to be redefined (e.g. to get new default behavior),this should NOT be done by just renaming them with a simple '#define func_new func_old'.Instead, macros should be used like it was done for older XL C/C++ compi...

Ship as PDSE for performance

With C header files in PDSes they cannot be cached in Z/OS and every compile needs to fetch from disk. If these were in PDSEs they they can be cached and avoid the I/O. See https://colinpaice.blog/2020/11/23/avoiding-i-o-by-caching-your-pdses-it-m...

Enabling the IBM LinuxONE and IBM Power 10 ( or later ) C/C++ Compilers to integrate with Intel oneAPI

Intel oneAPI is an open, cross-architecture programming model that frees developers to use a single code base across multiple architectures. The result is accelerated compute without vendor lock-in. for more information : https://www.intel.com/con...

Adding IBM Deep search with ChatGPT Codex (or IBM Coding Services) by AI driven Coding training and inference ( can be Human Supervised)

Using IBM Deep search with Coding services will train the AI System for Optimized code and it will make the software development more efficient in coding, testing, tracking and debugging. Also may be add the AI driven DevOps Orchestration

Support for __ptr64 qualifier in LE C

LE C compiler should support the __ptr64 qualifier for 64-bit pointers in 31-bit (or 64-bit) code, as it does for Metal C. Furthermore, EDCDSECT should convert a 64-bit addresses (declared as "AD") to "void * __ptr64", for consistency.

Port patch https://www.ibm.com/support/pages/apar/PI41717 from zOS for IBM i

Please port the patch https://www.ibm.com/support/pages/apar/PI41717 which is for zOS to IBM i, the same error exists in the sources of the IBM i hash function.

Add support to EDCDSECT for generating Doxygen-compatible comments

We have a product that has many data areas in common between C/C++ code and Assembler code. We generate the C/C++ header files from the Assembler DSECTs using the EDCDSECT utility provided by z/OS XL C/C++. We generate documentation for the C/C++ ...

Support for generating AMODE 31 with xlclang++

CICS does not support 64 bit LE programs. xlclang++ cannot be used for CICS development.

Have C compile optionally use non deprecated instruction BALR and use BASR

Today if I want to call an assembler program from C it uses BALR. This is deprecated, and I need special code to support it. The compiler needs an option to say "use Branch and save (BASR) instead of BALR"

Enhance constant propagation

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