From: Ben Harris Date: Tue, 24 Apr 2007 00:23:14 +0100 (BST) Subject: [Formal] fxlogical-shift-left and fxlogical-shift-right used but not defined. submitter: Ben Harris type: Defect priority: Minor component: Arithmetic version: 5.92 summary: fxlogical-shift-left and fxlogical-shift-right used but not defined. The definitions on page 38 of fxbit-field, fxcopy-bit-field, and fxrotate-bit-field all use fxlogical-shift-left, and two of them use fxlogical-shift-right. Neither of these procedures is defined. fxlogical-shift-left can obviously safely be replaced with bitwise-arithmetic-shift-left. I suspect that overflow considerations prevent the use of fxarithmetic-shift-left in fxcopy-bit-field and fxrotate-bit-field. fxlogical-shift-right appears to only be called with positive arguments, so it can safely be replaced with fxarithmetic-shift-right. RESPONSE: Uses of fxlogical-shift-left and fxlogical-shift-right have been eliminated.
