Hi Sterling, this series fixes two bugs in xtensa.md: - generation of non-existent instructions for division/reciprocal/square root - generation of pre- or post-increment floating point loads/stores depending on whether the core supports former or latter.
These changes allow building gcc for modern xtensa cores with FPU. Tested on xtensa-linux-uclibc.
