The type-safe attribute patch introduced a regression that can occur when the DW_AT_bit_offset value is negative. This can happen with some Ada programs. This patch fixes the problem. It also fixes a minor oddity in the existing scalar storage test -- this test was intended to assign a smaller number of bits to the field. 2020-10-09 Tom Tromey <tromey@adacore.com> * dwarf2/read.c (dwarf2_add_field): Handle signed offsets. gdb/testsuite/ChangeLog 2020-10-09 Tom Tromey <tromey@adacore.com> * gdb.ada/scalar_storage/storage.adb (Another_Range): New type. (Rec): Add field. Fix range. * gdb.ada/scalar_storage.exp: Update.
