Once the build has -completed, run "make check" to verify that all (math) checks succeed. -If these checks succeed, you should also run the following commands to -verify that the new libm doesn't pollute the name-space and has proper -size-info for the data objects: - - $ cd $LIBC/src/sysdep/ia64/fpu - $ import_check $OBJ/math/ - -There should be no (unexpected) errors reported by this script. - -As an optional step, you may also want to confirm that the new libm -exports the exact same global symbols as the old one. - -If you want to see the changes introduced by the "import_intel_libm" -script, you can run the commands: - - $ cd $LIBC/src/sysdep/ia64/fpu - $ import_diffs - -That's it. |
