Hi all, Please find attached the patch { 0001-Enable-vector-register-visibility-in-core-file-for-A.patch} This patch will enable vector register visibility when AIX FOLKS do core file analysis especially using applications like GDB. Kindly check the outputs with the patch and without the patch. Changes are visible in bold for the output with patch. Do let me know if any changes are required. If not kindly commit the same. Thanks and regards, Aditya. ------------------------- Output without patch:- ./gdb ~/gdb_tests/bll_core core.13828468 GNU gdb (GDB) 14.0.50.20230221-git Copyright (C) 2023 Free Software Foundation, Inc.
