Support for generating AMODE 31 with xlclang++

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

XL Fortran Bogus Error on Assumed Shape Dummy Argument of BIND(C) Procedure

The XL Fortran compiler gives a bogus error message for the below valid Fortran program. The restriction that presumably generates this error message was replaced in Fortran 2018 standard (sec 18.3.6 point 5). Furthermore, the XL compiler provides...

XL C/C++ for z/OS Compiler Features

We'd like to move to using the newer Clang-based XL C/C++ compiler, but we need some features that are not present in the newer product, namely: AMODE31 supportEBCDIC supportHex float support

The C++ interface for demangling new cxxabi names(generated by xlclang 16.1) are not implemented.

The C++ interface for demangling new cxxabi names(generated by xlclang 16.1) are not implemented. The C++ interface could only demangle old C++ names generated by xlC.

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...

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...

Support norm2 in XL Fortran 2008

As part of the Fortran 2008+ standards, norm2 is widely supported by various compiler toolchains. This RFE is to request support for the norm2 intrinsic be added to IBM XL Fortran 2008.
