Raise a severe error if an unknown instruction is generated

If the Compiler/Optimizer generates an invalid unknown instruction (UNKWN), it have to raise a Severe Error. The assembly list shows unknown ?UNKWN? instructions: 000027 | ALRK r8,r7,r9 000027 | UNKWN r15,r3 000027 | UNKWN r8,r6 000027 | C r0,s.uw...

Add support for function inlining at OPT(0) [Metal C]

The METAL option of the xlc compiler does not support selectively inlining functions without optimizing the rest of the code We would like to be able to use a compiler attribute (such as "__always_inline__" or "_inline") to force inlining of certa...

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...

#pragma report should be extended to C

It is very frustrating that this pragma is not available in C, but only in C++!

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

Perform optimizations based on __attribute__((__malloc__))

Currently, __attribute__((__malloc__)) does not work as documented in the compiler docs. The documentation infers that the compiler performs certain optimizations when using __malloc__ attribute. However, it appears that the compiler simply tolera...

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.

Using CPACF with HW built-In instructions

ISV likes to use HW Crypto support of CPACF (see Principles of Operation) in their applications running on z/OS. As of requiremts of their architecture and as of performance reasons, they do not use ICSF. So they have to use the CPACF instructions...

Provide Fortran compiler option to force variables to be explicitly declared

The IMPLICIT none statement is available to us, but it has to be coded in every single program, subroutine and function, whereas a compiler option would not require a code modification to enforce explicit declarations. The PL/I compiler has the RU...
