Heikki Linnakangas 936546dcbc Optimize pg_comp_crc32c_sse42 routine slightly, and also use it on x86. ... Eliminate the separate 'len' variable from the loops, and also use the 4 byte instruction. This shaves off a few more cycles. Even though this routine that uses the special SSE 4.2 instructions is much faster than a generic routine, it's still a hot spot, so let's make it as fast as possible. Change the configure test to not test _mm_crc32_u64. That variant is only available in the 64-bit x86-64 architecture, not in 32-bit x86. Modify pg_comp_crc32c_sse42 so that it only uses _mm_crc32_u64 on x86-64. With these changes, the SSE accelerated CRC-32C implementation can also be used on 32-bit x86 systems. This also fixes the 32-bit MSVC build.		2015-04-14 23:58:16 +03:00
