  • Kernel: 3.2.34
  • Issue: CentOS 6.2
  • Postgresql: 9.2
  • GCC: 4.8.0
  • CFLAGS: -march=native -O3 -mavx -Wall -Wmissing-prototypes -Wpointer-arith -Wdeclaration-after-statement -Wendif-labels -Wmissing-format-attribute -Wformat-security -fno-strict-aliasing -fwrapv -fexcess-precision=standard
  • LDFLAGS: -Wl,--as-needed -Wl,-rpath,'/opt/pg92/lib',--enable-new-dtags
gcc -mavx
  • -mavx，gcc会尽量生成avx指令

注意avx，关注一下链接,需要avx和sse的区别
