            Bug ID: 98728
           Summary: [11 regression] Several debug tests FAIL with DWARF-5
           Product: gcc
           Version: 11.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: debug
          Assignee: unassigned at gcc dot gnu.org
          Reporter: ro at gcc dot gnu.org
                CC: mark at gcc dot gnu.org
  Target Milestone: ---
            Target: i386-pc-solaris2.11, sparc-sun-solaris2.11,
                    x86_64-pc-linux-gnu

With the switch to DWARF-5, two debug tests have started to FAIL:

+FAIL: g++.dg/debug/dwarf2/constexpr-var-1.C   scan-assembler-times 
DW_AT_const_expr 2

32 and 64-bit Solaris/SPARC and x86, Linux/x86_64

+FAIL: gcc.dg/debug/dwarf2/dwarf-float.c scan-assembler 0x10.*DW_AT_byte_size

32-bit Solaris/x86 and Linux/x86_64

Besides, there were many changes to guality tests on Linux/x86_64, both tests
previously XPASSing now XFAIL again, as well as several new FAILs.
