How does clang generate non-looping code for sum of squares?

TL:DR: Yes, clang knows the closed-form formulas for sums of integer power series, and can detect such loops. Smart humans have taught modern compilers to recognize certain patterns of operations and replace them with operations not present in the source, e.g. for rotates and even popcount loops and bithacks. And for clang/LLVM specifically, also closed-form … Read more

CocoaPods arm64 issue

Select the Pods project Change Build Active Architecture Only from Yes to No. That worked for me. Note: CocoaPods Troubleshooting Guide recommends matching the Debug setting in your Xcode project, rather than changing the Pod’s Build Active Architecture Only. As long as they match it seems to fix the problem.

iOS app submission : missing 64-bit support

Use “Standard architectures” like this: Architecture: “Standard architectures” arm7, arm64 Valid Architectures: “arm64” , armv7… Build Active Architecture Only – NO (specially… if your connected device is not arm64 compatible) like this: Additionally, unplugging iphones and ipads from the mac has been known to help, especially if they are 32-bit versions.

Differences between arm64 and aarch64

AArch64 is the 64-bit state introduced in the Armv8-A architecture (https://en.wikipedia.org/wiki/ARM_architecture#ARMv8-A). The 32-bit state which is backwards compatible with Armv7-A and previous 32-bit Arm architectures is referred to as AArch32. Therefore the GNU triplet for the 64-bit ISA is aarch64. The Linux kernel community chose to call their port of the kernel to this architecture … Read more

What is difference between arm64 and armhf?

armhf stands for “arm hard float”, and is the name given to a debian port for arm processors (armv7+) that have hardware floating point support. On the beaglebone black, for example: :~$ dpkg –print-architecture armhf Although other commands (such as uname -a or arch) will just show armv7l :~$ cat /proc/cpuinfo processor : 0 model … Read more
