From 38d3690bda3fe217ea72903859907916a5429c6e Mon Sep 17 00:00:00 2001 From: Matheus Ferst Date: Wed, 29 Jun 2022 13:29:03 -0300 Subject: target/ppc: implement cbcdtd MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implements the Convert Binary Coded Decimal To Declets instruction. Since libdecnumber doesn't expose the methods for direct conversion (decDigitsToDPD, BCD2DPD, etc.), the BCD values are converted to decimal32 format, from which the declets are extracted. Where the behavior is undefined, we try to match the result observed in a POWER9 DD2.3.
