The aarch64 platform provides an assembly-optimized implementation of gen_icf_map_h1_aarch64. However, this optimized path was not correctly enabled for deflate compression level 3. After correcting the invocation logic, deflate throughput increased by 11%.
This optimization has been validated with igzip_perf on the ZXIC(R) ZhuFengXin Processor platform：
./igzip/igzip_perf -f 3 -y 0 -b 1024 silesia.tar (11% performance improvement)
