  [/builddir/build/BUILD/sleef-3.7.0-build/sleef-3.7/src/arch/helperpower_128.h: In function ‘vtruncate_vi_vd’:
/builddir/build/BUILD/sleef-3.7.0-build/sleef-3.7/src/arch/helperpower_128.h:410:9: error: implicit declaration of function ‘__builtin_vsx_xvcvdpsxws’; did you mean ‘__builtin_vsx_xvcvdpsxds’? [-Wimplicit-function-declaration]
]: [Built-in function `__builtin_vsx_xvcvdpsxws` was removed in GCC 15.]

Issue: GCC 15 removed several PowerPC 64 built-in functions. This code uses `__builtin_vsx_xvcvdpsxws` which causes the build to fail.
Resolution: Migrate your code base away those removed built-in functions.
