iOS framework separates and merges multiple CPU architectures, separating and merging simulators and real machinesIf you are using a framework that supports a variety of CPU architectures for real machines and emulators, and you need one or more of these, you can detach the various schemas from the framework and then merge the specific ways you need them, in the following examples:First separate the ARMV7 arm64 from the framework, or armv7s lipo Xxxx.

Create aggregate to merge the simulator with the generic framework of the real machineThen create the merge script under build phases new Run script phase:# Constantssf_target_name=${project_name} #自定义的用来存放最后合并的frameworkUNIVERSAL_OUTPUTFOLDER=${build_dir}/${configuration}-Universal#iphone_device_build_dir=${build_dir}/${configuration}-Iphoneosworkspace_name=${project_name}.xcworkspaceyo_scheme=${project_name} #clean build is the first to clear the original Buildxcodebuild-workspace ${workspace_n

The $ constants at the back are all absolute numbers.There is no need to know what the code is doing, because you first need to understand the registers and calling conventions of the functions. Note: in the example above, the registers and constants are preceded by a bunch % of and $ . It's a way of expressing. However, there are two main ways o

parameter and trying to close it, the ascending speed is arranged in descending order, it is simple to organize several: Only the ARMV7 instruction set is supported. The instruction set on the phone belongs to the ARM series, from the old to the new armv7, armv7s and arm64. The new instruction set can be compatible with the old model, but the old model cannot be compatible with the new instruction set. By default, our packages will have ARMV

instructions of the function to open the storage of the function return address, so take the stack of data sorta is correct. If we want to comb the order relationship, then the system design will be more complex. Since ARM64 does not seem to be involved at this point, this article will not be detailed in this case. Therefore, the non-leaf function can be considered simply, get the return address from the stack. 2) What are the key instructions that f

For testing Kvm/qemu, prebaked images cloud images nice. However, there is a few steps to get started. We need a recent Qemu (2.5 is good enough). An EFI firmware are needed, and cloud-utils, for customizing our VM. sudo apt install-y qemu qemu-utils cloud-utils wget https://releases.linaro.org/components/kernel/uefi-linaro/ 15.12/RELEASE/QEMU64/QEMU_EFI.FD wget https://cloud-images.ubuntu.com/xenial/current/ Xenial-server-cloudimg-arm64-uefi1.img Clo

) Solution: Xcode upgrade to 6.1.1 The default is to have all apps compiled with 64-bit compilers. Originally in the Xcode6.0 when the default architectures only (arm7,armv7s), to 6.1.1 default to take the arm64 parameters. 1.1. Select Targets->build settings->architectures. Change the build active architectures to NO. 2. Delete the arm64 parameters in the valid architectures below. Or: Double-click Archi

For kernel, the call tracking for a function is over, and we can't always go back to the function call of user space. As we said in the previous section, the hardware will turn off the IRQ, where we can turn on the interrupt processing of this CPU via ENABLE_IRQ. Ct_user_exit and Context track

First, prefaceOrdinary spin lock treats reader and writer equally, RW spin lock gives reader higher priority, then there is no mechanism to let writer priority lock? The answer is Seqlock. This article mainly describes the Linux kernel 4.0 in the Seqlock mechanism, first of all, seqlock work principle, if you want to scratch, then understand the concept of the East is OK, that is, the second chapter, of course, I still recommend common driver engineer to understand the Seqlock API , the third ch

However, it is found that the project can be compiled on the real machine, but it has not been programmed on the simulator. Problem solving: After studying the compilation option and then adding the x86_64 schema, recompiling the project can be successfully
