From 9f6839d4b1721524a10c77768f73697cf1724ce5 Mon Sep 17 00:00:00 2001 From: Stuart Brady Date: Sun, 12 Jul 2009 20:09:40 +0100 Subject: [PATCH] Remove dead i386 assembly code from softmmu_header.h This patch removes dead i386 assembly code from softmmu_header.h. The code is conditional on ASM_SOFTMMU, which is never defined. Optimisation for the fast path is already handled by tcg_out_qemu_ld() and tcg_out_qemu_st(), so there seems to be little need for this code.
