sparse-llvm results from trying to compile a largish program

[Dibyendu Majumdar]

Hi,

I tried to compile a Lua implementation using sparse-llvm. This
particular implementation is called 'minilua' as it is a cut down
version of Lua 5.1.5 created by Mike Pall for the LuaJIT project.

I had to change all static initializations of course as these are
unsupported in sparse-llvm. I also had to add support for casting
floating point values to integer type in 'op_cast' implementation.

sparse-llvm managed to consume the program after these changes but
there were many LLVM errors reported, which indicates that the
generated code is incorrect.

I have saved the results from this exercise here:

https://github.com/dibyendumajumdar/dmr_c/tree/master/tests/minilua

Hopefully this will help in analysing the errors and deciding how to fix them.

Thanks and Regards
Dibyendu

I have fixed a bunch of issues in my repository - and the updated
error list now is much reduced! Please see the link above for the
remaining errors and the generated code.

The code now compiles without errors but crashes when run!
