--- Comment #7 from Michael Meissner <meissner at gcc dot gnu.org> ---
The following options were used for LRA code generation:
-DSPEC_CPU -DNDEBUG -I.  -g -mlittle -save-temps=obj -ffast-math -O3
-mveclibabi=mass -mcpu=power8 -mrecip=rsqrt -fpeel-loops -funroll-loops
-ftree-vectorize -fvect-cost-model -msave-toc-indirect
-fno-aggressive-loop-optimizations -mno-pointers-to-nested-functions -mlra 
-m64 -I/opt/at8.0/include
-I/opt/at8.0/lib/gcc/powerpc64le-linux-gnu/4.9.4/include -fgnu89-inline      
-DSPEC_CPU_LP64 -DSPEC_CPU -DSPEC_CPU2006 -DINLINE=
