+Generate code that uses (does not use) the optional PowerPC
+architecture instructions in the General Purpose group, including
+floating-point square root.
+
+@item recip-precision
+@itemx no-recip-precision
+@cindex @code{target("recip-precision")} attribute
+Assume (do not assume) that the reciprocal estimate instructions
+provide higher precision estimates than is mandated by the powerpc
+ABI.
+
+@item string
+@itemx no-string
+@cindex @code{target("string")} attribute
+Generate code that uses (does not use) the load string instructions
+and the store string word instructions to save multiple registers and
+do small block moves.
+
+@item vsx
+@itemx no-vsx
+@cindex @code{target("vsx")} attribute
+Generate code that uses (does not use) vector/scalar (VSX)
+instructions, and also enable the use of built-in functions that allow
