           Summary: Inconsistent name mangling of bool (a relic of 'bit')
           Product: D
           Version: 0.160
          Platform: PC
        OS/Version: Windows
            Status: NEW
          Severity: minor
          Priority: P4
         Component: DMD
        AssignedTo: bugzilla digitalmars.com
        ReportedBy: clugdbug yahoo.com.au


Long ago, bit was name-mangled as 'x', but now that bit is gone, bool is
name-mangled as 'b'.
However, for function parameters, bool is still name-mangled as 'x' rather than
the expected 'b'.

bool.mangleof == "b"

but...

(void function(bool)).mangleof ==  "PFxZv"

instead of the more natural "PFbZv"

This means that one of the few unused name-mangling letters ('x') is wasted.
Probably an implementation quirk rather than a bug.

mtype.c line 174-175,

    mangleChar[Tbit] = 'b';
    mangleChar[Tbool] = 'x';

This should be changed so they are both 'b'.
