d94f4ac079 Add support for multiplication. 
Multiplication instructions don't set the overflow flag so we need
to manually check, which is why this is more complicated than
addition.

d256d99659 Add support for floating point add/sub. 2016-12-20 12:09:32 -05:00

5df5e1f144 Add support for integer add/subtract. 
Still need to support floating point operations. Multiplication is a
little more complicated because it doesn't set the overflow flag.

e467d784a9 Fix floating point fallback code for for loops. 
Adds a dependency on clfi. Not sure how to work around (don't
really want to always introduce a temporary).

24bdb7576d Add debug options to Makefile. 
We're going to need these for a while, so better to put in the
repository. Once we're happy things are working we can disable
the debug info and enable optimizations again.

2dcbf5be3e Implement more functions in the VM. 
Also adds segmentation faults to stubbed out functions to make it
easier to work out what the control flow is.

7644f40b1a Add more interpreter code. 
Compilation is currently broken, a label is missing.
 2016-12-13 18:31:43 -05:00

0b120ac64b Add partial implementation of vm_cpcall. 
Currently works if the call returns 0. Haven't yet written the code
needed to handle the non-zero case.

625aad5da0 Make LuaJIT compile on s390x. 
I've disabled both the JIT and FFI for now. I've also stripped almost
all of the assembly out of vm_s390x.dasc, leaving only labels for the
most part. This is enough to get LuaJIT to compile but of course if
you try and run it it will explode.

The idea now is to re-add enough functionality to get a very basic
Lua program to run.
 2016-12-09 16:28:39 -05:00

052eb69750 Make host/buildvm_asm.c compile. 
I've added a rough implementation of this code. It is untested but
does compile.

no JUMP instruction found for s390x used BRANCH RELATIVE on CONDITION instead (brc)

5887962b0e Add assembly for decoding instructions. 
Still guessing at this point. This code will need to be changed.

dbf789536c Fix stack frame layout. 
f8-f15 are callee-saved (not f0,f2,f4 and f6). There isn't space
for them in the caller's stack frame so we need to increase the
size of the interpreter's stack frame.
 2016-11-23 17:30:10 -05:00
Michael Munday
5a69b4638a Fixup the save/restore register macros. 
I believe these macros obey the C calling convention, so we need to
allocate our stack frame and save all callee-save registers. We
can tune it later if it turns out we don't need all the registers.
 2016-11-22 13:58:10 -05:00

d505a0e0ba Cleanup. 2016-11-22 13:47:35 -05:00
Michael Munday
d50f8aa92b Add preliminary frame offsets. 
These are educated guesses at this point. We might need more stack space because
we don't have many free registers available.
