From 167e4cdc29985e69769452fade698c5b9df78b3d Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Thu, 3 Mar 2016 12:11:18 +0000 Subject: linux-user: arm: Remove ARM_cpsr and similar #defines The #defines of ARM_cpsr and friends in linux-user/arm/target-syscall.h can clash with versions in the system headers if building on an ARM or AArch64 build (though this seems to be dependent on the version of the system headers). The QEMU defines are not very useful (it's not clear that they're intended for use with the target_pt_regs struct rather than (say) the CPUARMState structure) and we only use them in one function in elfload.c anyway. So just remove the #defines and directly access regs->uregs[].
