    Support for calling Non-LE OS 31 linkage from xlclang++ in 64 bit mode.

    Allow calling existing legacy Non-LE OS 31 from xlclang++ in 64 bit mode. Allow the generation of the OS 31 parameter list. It is the responsibility of the caller to make sure addresses and memory are below the bar. The compiler merely generates O...

    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...

    Document and support #pragma once in both C/C++

    The z/OS C++ compiler supports the #pragma once directive. This is undocumented and not supported for the C language. This feature should be documented and supported for both the C and C++ languages.

    XL C/C++ compiler setting to disallow vector (VMX/VSX) instructions

    Request for the compiler to support code generation consistent with an AIX tuning of allow_vmx=0. The AIX tuning rejects all vector instructions, treating them as illegal operations. The compiler should have a corresponding option to completely di...
