I am using MPC5744P for a project.
I have set target option: -tPPCE200Z4251N3VEF:simple for compiler&assembler&linker of Windriver.
That is because I want to use EFPU (Embedded floating-point unit) to speed up the calculation.
However, when I was compiling X.c which have floating-point divide calculation, there always have compile error.
The compile error is as follow:
"XXX\llopt unrecognize line: efsdiv ?a8, ?a7, ?a6" . It seems like assembler can't recognize efsdiv instruction, but, it's unreasonable.
Actually, "efsdiv" instruction has been written in "E200Z4 reference manual".
PS:
1. The core of MPC5744P is E200Z4251N3;
2."llopt" is an executive program file of Windriver which is using for optimizing assembly file.
