Hi, i have some issue on an inplace vetx.32 instructions. I post it on the Cortex A forum. Who has a tip or workaround as it is too slow on A7,A8,A9, etc... ? thanks

Hi,
Which compiler are you using?
Thanks,
Paul.
Hi Paul, gcc 8.3 but i did bench on many ARM (a7,a8,a9,a53,a72) and the results is homogeneous (different also) but seems logical. How ever i am not that much happy to spend so much cycles (5 on A7) for a single line instruction. I am happy if you can ask the team some workaround. cheers. bruno
This is the Arm Compiler forum. Your query would be better answered in the GCC toolchain forum: https://community.arm.com/developer/tools-software/oss-platforms/f/gnu-toolchain-forum
Thanks
