What compiler are you using? If it emits code which uses integer unit for FPU/vector operations, it's better to use --disable-neon-support to build libgcrypt, instead. > Is this a problem ? the busybox code seems no hardware support. why > libgcrypt is slower so much than busybox. It looks like busybox code only uses integer operations (no vector operations) for ARM. -- _______________________________________________ Gnupg-users mailing list Gnupg-users@gnupg.org http://lists.gnupg.org/mailman/listinfo/gnupg-users
