Hello Is -mfpmath=both for i386 and x86-64 still experimental in gcc 4.3, as the in the online manual page ?
`sse,387'`sse+387'`both'Attempt to utilize both instruction sets at once. This effectively double the amount of available registers and on chips with separate execution units for 387 and SSE the execution resources too. Use this option with care, as it is still experimental, because the GCC register allocator does not model separate functional units well resulting in instable performance. Thank you, Timothy Madden
