Lua Compiler

A Bison+Flex Lua 5.1 compiler.

Has complete grammar support, x86 target however is limited but works for a few basic testcases.

In test.sh you can see which test cases that should work so you can get a hint on what is implemented.

This is the second assignment in the course DV1465, Compiler Techniques at Blekinge Institute of Technology.

Supported compilers (versions tested)

• GCC (Compiler+target) (6.2.1, 5.4.0, 4.9.2)
• Clang (Compiler+target) (3.5.2)

Flaws

• Incomplete type system
• Function declarations can only have max 4 parameters
• Function calls currently only supports one parameter
• Stack logic needs improvements to save stack space
• Lots of memory leaks
• Max 30 operands bug for inline assembly
