Paul Mackerras	9d285a265c	core: Add support for single-precision FP loads and stores This adds code to loadstore1 to convert between single-precision and double-precision formats, and implements the lfs* and stfs* instructions. The conversion processes are described in Power ISA v3.1 Book 1 sections 4.6.2 and 4.6.3. These conversions take one cycle, so lfs* and stfs* are one cycle slower than lfd* and stfd*.

Paul Mackerras	ec9b27660f	execute: Copy XER[SO] to CR for cmp[i] and cmpl[i] instructions We were copying in XER[SO] for the dot-form instructions but not the explicit compare instructions. Fix this. Signed-off-by: Paul Mackerras <paulus@ozlabs.org>	5 years ago

Michael Neuling	4d5abfb430	Remove dynamic ranges from code Some VHDL compilers like verific [1] don't like these, so let's remove them. Lots of random code changes, but passes make check. Also add basic script to run verific and generate verilog. 1. https://www.verific.com/ Signed-off-by: Michael Neuling <mikey@neuling.org>	5 years ago
