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...

XLF: Compiler should detect and isolate the source of non-conforming Openmp code using local pointers for data maps.

SalesForce Case: TS001878905PMR: 80808,227,000 The use case reproducer for this issue is an OpenMP Fortran implementation that uses local, temporary pointers to do data mapping. The implementation does not conform to the OpenMP spec but the compil...

XLF: Support for Fortran 2008 feature move_alloc

The feature is described in section "5.3 Allocatable components of recursive type" from the Fortran 2008 summary document available at https://wg5-fortran.org/N1801-N1850/N1828.pdf and appended here: A recursive type is permitted to be based on al...

XL: Support linking objects compiled with clang++ and xlc or xlf that use OpenMP GPU offloading

SalesForce Case TS001968579PMR 82483,227,000 XLF compiler: Errors linking objects compiled with clang++ and xlc or xlf that use OpenMP GPU offloading. LLNL is having problems linking objects that were compiled using the clang++ (LLVM) and XLF (or ...

RFE for header file cache optimization on C compiler

We would like to see the following implemented with the C compiler frontend just like it is for the C++ compiler frontend beginning with Xlc 12.1: -qxflag=dircache[,m[,n]] where m and n are optional * m is a integral prime number between 2 and 71 ...

XLF: request support for -shared flag consistent with the XLC usage

The XLC compiler accepts the "-shared" flag as an alias to "-qmkshrobj" to create shared object (.so) files, but the XLF compiler does not. The XLF option -shared is not documented but is not identified as invalid when it is used. Using -shared do...

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...
