rs6000: Fix ICE for invalid constants in built-in functions
For invalid constant operand values used in built-in functions, return
const0_rtx to signify an error occurred during expansion.
2025-01-16 Peter Bergner <bergner@linux.ibm.com>
gcc/
* config/rs6000/rs6000-builtin.cc (rs6000_expand_builtin): Return
const0_rtx when there is an error.
gcc/testsuite/
* gcc.target/powerpc/mma-builtin-error.c: New test.
