[powerpc] add 'volatile' to asm
Add 'volatile' keyword to a few asm statements, to force the compiler to generate the instructions therein. Some instances were implicitly volatile, but adding keyword for consistency. 2019-06-19 Paul A. Clarke <pc@us.ibm.com> * sysdeps/powerpc/fpu/fenv_libc.h (relax_fenv_state): Add 'volatile'. * sysdeps/powerpc/fpu/fpu_control.h (__FPU_MFFS): Likewise. (__FPU_MFFSL): Likewise. (_FPU_SETCW): Likewise.
