      xtensa: add HW FPU sequences for DIV/SQRT/RECIP/RSQRT · 2b7e7fc4
      jcmvbkbc authored
      Use new FPU instruction sequences documented in the ISA book to
      implement __divsf3, __divdf3, __recipsf2, __recipdf2, __rsqrtsf2,
      __rsqrtdf2 and __ieee754_sqrtf and __ieee754_sqrt.

      xtensa: fix libgcc build with --text-section-literals · 1fa780ac
      jcmvbkbc authored
      Functions __muldf3_aux, __divdf3_aux, __mulsf3_aux and __divsf3_aux
      don't start with leaf_entry, so they need explicit .literal_position,
      otherwise libgcc build fails in the presence of --text-section-literals.

      	* config/xtensa/ieee754-df.S (__muldf3_aux, __divdf3_aux): Add
      	.literal_position before the function.
      	* config/xtensa/ieee754-sf.S (__mulsf3_aux, __divsf3_aux):

      	(TRAMPOLINE_SIZE): Two versions of the trampoline have different sizes.
      	(INITIALIZE_TRAMPOLINE): Use xtensa_initialize_trampoline.
      	* config/xtensa/ieee754-df.S (XCHAL_NO_MUL): Define.
      	(__muldf3): Use CALL12 instead of CALL0 to invoke .Lmul_mulsi3
      	helper when not using the CALL0 ABI.  Change .Lmul_mulsi3 to match.
      	* config/xtensa/lib1funcs.asm (__umulsidi3): Likewise.
      	* config/xtensa/ieee754-sf.S (__mulsf3): Likewise.
