Hi: I found although there are standard pattern names such as "ceilm2/floorm2", there is no insn pattern in mips.md for such float insns on mips target. further more, there is no ceil/floor rtl code in rtl.def either.
based on these facts, I assuming those float insns are not supported by gcc, but don't know why, seems not difficult to add such insns. Did I miss anything important? please help, thanks. -- Best Regards.
