That's a *really* old GCC version.

The functions you are mentioning in 3 are GCC built-ins, not library
functions.

Hello ,



I’m using Gnu compiler , version 3.3.2 , (product vxworks , HW PPC ) , I
have the following questions:



1.       Is it ok to replace the following function:

a.       vec_xl  to vec_ld

b.       vec_xst to vec_st

2.       but , when I replace the function calls to vec_ld , I get
compilation errors,like

*a.*          *cannot  convert `vector short unsigned int' to `vector
unsigned char' in , and others*

b.       I can’t update the compiler version, is there a workaround, or an
old X265 version that supports vec_ld , vec_xst functions.

3.       I’m missing the following function (gblic) , how to resolve the
problem?

a.       *__builtin_clz**, __builtin_ctz*

b.       *__sync_fetch_and_or**, __sync_fetch_and_and,
__sync_add_and_fetch, __sync_fetch_and_add*
