+ Fixed bug in operator <c>band</c> of two negative
+ operands causing erroneous result if the absolute value
+ of one of the operands have the lowest <c>N*W</c> bits as
+ zero and the other absolute value is not larger than
+ <c>N*W</c> bits. <c>N</c> is an integer of 1 or larger
+ and <c>W</c> is 32 or 64 depending on word size.</p>

+ <list>
+ <item>
+ <p>Added an optional <c>./configure</c> flag to compile
+ the emulator with spectre mitigation:
+ <c>--with-spectre-mitigation</c></p>
+ <p>Note that this requires a recent version of GCC with
+ support for spectre mitigation and the
+ <c>--mindirect-branch=thunk</c> flag, such as
+ <c>8.1</c>.</p>
