This patch similarly to the AArch64 one enables Dot Product support by default for the Cortex-A55 and Cortex-A75 which have hardware support for these instructions.
gas * config/tc-arm.c (arm_cpus):
Change FPU_ARCH_CRYPTO_NEON_VFP_ARMV8
into FPU_ARCH_CRYPTO_NEON_VFP_ARMV8_DOTPROD.
include * opcode/arm.h (FPU_ARCH_CRYPTO_NEON_VFP_ARMV8_DOTPROD):
New macro.
