From fab7fe426fa5325f93c931ffbe25f4e024b1ced4 Mon Sep 17 00:00:00 2001 From: Tom Musta Date: Tue, 7 Jan 2014 10:05:59 -0600 Subject: target-ppc: Add ISA2.06 Float to Integer Instructions This patch adds the four floating point to integer conversion instructions introduced by Power ISA V2.06: - Floating Convert to Integer Word Unsigned (fctiwu) - Floating Convert to Integer Word Unsigned with Round Toward Zero (fctiwuz) - Floating Convert to Integer Doubleword Unsigned (fctidu) - Floating Convert to Integer Doubleword Unsigned with Round Toward Zero (fctiduz) A common macro is developed to eliminate repetitious code. Existing instructions are also refactoried to use this macro (fctiw, fctiwz, fctid, fctidz).
