13.2 EDK: _mh files Are Not Found in the EDK Install Directory


Page 112 of the Embedded System Tools Reference Manual EDK v13.2 (UG111) says that I can specify _mh in the library name for the extended hardware multiplier.

I have searched $XILINX_EDK/gnu/microblaze/<platform>/microblaze-xilinx-elf/lib, but I am unable to find them. How can I use these libraries?


The libc and ilbm libraries have not been compiled to use the extended hardware multiplier because it has minimal impact on the standard libraries. The extended multiplier can still be enabled in user code by adding the -mxl-multiply-high compiler option.
