 [flang] Add UNSIGNED (#113504) 2024-12-18T15:02:37+00:00 Peter Klausler pklausler@nvidia.com 2024-12-18T15:02:37+00:00 fc97d2e68b03bc2979395e84b645e5b3ba35aecd Implement the UNSIGNED extension type and operations under control of a language feature flag (-funsigned). This is nearly identical to the UNSIGNED feature that has been available in Sun Fortran for years, and now implemented in GNU Fortran for gfortran 15, and proposed for ISO standardization in J3/24-116.txt. See the new documentation for details; but in short, this is C's unsigned type, with guaranteed modular arithmetic for +, -, and *, and the related transformational intrinsic functions SUM & al.

 [flang] Support -f[no-]realloc-lhs. (#120165) 2024-12-17T17:06:05+00:00 Slava Zakharin szakharin@nvidia.com 2024-12-17T17:06:05+00:00 9d33874936d83b8ddf5d028d313d810214f00f20 -frealloc-lhs is the default. If -fno-realloc-lhs is specified, then an allocatable on the left side of an intrinsic assignment is not implicitly (re)allocated to conform with the right hand side. Fortran runtime will issue an error if there is a mismatch in shape/type/allocation-status.

 [flang][Driver] Support -print-supported-cpus and associated aliases (#117199) 2024-11-22T18:57:03+00:00 Tarun Prabhu tarun@lanl.gov 2024-11-22T18:57:03+00:00 23d7a6cedb5198535086a67586487f19effbd411 The aliases are -mcpu=help and -mtune=help. There is still an issue with the output which prints an example line that references clang. That is not fixed here because it is printed in llvm/MC/SubtargetInfo.cpp. Some more thought is needed to determine how best to handle this. Fixes #117010
