Mainline does not generate movdqa insn anymore. However:
g++ -O1 -msse -mfpmath=sse -fomit-frame-pointer -finline-limit=2000 pr16111.cpp
./a.out
extents (-27.500000 -27.500000 -0.000000 -0.000000)
g++ -O2 -msse -mfpmath=sse -fomit-frame-pointer -finline-limit=2000 pr16111.cpp
./a.out
extents (0.000000 0.000000 2.018096 2.018096)
g++ -O3 -msse -mfpmath=sse -fomit-frame-pointer -finline-limit=2000 pr16111.cpp
./a.out
extents (0.000000 0.000000 36.658997 36.658997)
Result is different, it depends on optimization level.
