"mfpmath=sse" violation

Asked by liuyix

when compiling program using "mfpmath=sse" and "-static" options , the generated program still contains x87 instruction.
objdump the program, I found the sincos function contains x87 instruction.
"gcc fft.o -O3 -pthread -D_POSIX_C_SOURCE=200112 -Wall -W -Wmissing-prototypes -Wmissing-declarations -Wredundant-decls -Wdisabled-optimization -Wpadded -Winline -Wpointer-arith -Wsign-compare -Wendif-labels -mfpmath=sse -o FFT -lm"

My ubuntu is ubuntu natty x86-64
uname -a :Linux ubuntu 2.6.38-8-generic #42-Ubuntu SMP Mon Apr 11 03:31:24 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux

Natyy is EOL in October. I suggest you abandon it soon and fresh install Precise. Not only is it the latest stable Ubuntu, it is also LTS giving it support until 2017...
