From 0bf79b2de8bf75093629b1861a49efca1dbc0356 Mon Sep 17 00:00:00 2001 From: Russ Cox Date: Wed, 4 Mar 2015 15:46:52 -0500 Subject: [PATCH] cmd/internal/obj/x86: take over i386 duty, clean up PINSRQ, CMPSD Make cmd/internal/obj/x86 support 32-bit mode and use instead of cmd/internal/obj/i386. Delete cmd/internal/obj/i386. Clean up encoding of PINSRQ, CMPSD to use explicit third arg instead of jamming it into an unused slot of a different arg. Also fix bug in old6a, which declared the wrong grammar. The accepted (and encoded) arguments to CMPSD etc are mem,reg not reg,mem. Code that did try to use mem,reg before would be rejected by liblink, so only reg,reg ever worked, so existing code is not affected. After this change, code can use mem,reg successfully. The real bug here is that the encoding tables inverted the argument order, making the comparisons all backward from what they say on the page. It's too late to swap them, though: people have already written code that expects the inverted comparisons (like in package math, and likely externally). The best we can do is make the argument that should and can take a memory operand accept it. Bit-for-bit compatibility checked against tree without this CL.
