            Bug ID: 30221
           Summary: linker script expression parser does not accept '~'
           Product: lld
           Version: unspecified
          Hardware: PC
                OS: FreeBSD
            Status: NEW
          Severity: normal
          Priority: P
         Component: ELF
          Assignee: unassignedbugs@nondot.org
          Reporter: emaste@freebsd.org
                CC: llvm-bugs@lists.llvm.org
    Classification: Unclassified

A bootloader component of FreeBSD/mips64 uses a linker script with an
expression containing a bitwise not (~), which lld does not accept:

line 53: malformed number: ~                                                    
  . = ((. + 0x1000) & ~(0x1000 - 1));
                      ^

The script in question can be found at
https://svnweb.freebsd.org/base/head/sys/boot/mips/uboot/ldscript.mips?annotate=296183#l53
