PR tree-optimization/32383
* targhooks.c (default_builtin_reciprocal): Add new bool argument.
* targhooks.h (default_builtin_reciprocal): Update prototype.
* target.h (struct gcc_target): Update builtin_reciprocal.
* doc/tm.texi (TARGET_BUILTIN_RECIPROCAL): Update description.
* tree-ssa-math-opts (execute_cse_reciprocals): Skip statements
where arg1 is not SSA_NAME. Pass true to targetm.builtin_reciprocal
when fndecl is in BUILT_IN_MD class.
(execute_convert_to_rsqrt): Ditto.
* config/i386/i386.c (ix86_builtin_reciprocal): Update for new bool
argument. Convert IX86_BUILTIN_SQRTPS code only when md_fn is true.
Convert BUILT_IN_SQRTF code only when md_fn is false.
testsuite/ChangeLog:
PR tree-optimization/32383
* testsuite/g++.dg/opt/pr32383.C: New test.
