\ No newline at end of file +C based TNSL compiler + + +Technically, this program is a TNSL to ASM transpiler, which works in two passes. + +### pass 1 + +The first pass loads struct, module, and function declarations into memory, and checks for +circular types. It also catalogs global variable definitions to later put into the data section. + +all first pass functions are prefixed with `p1_` + +### pass 2 + +The second pass generates the actual assembly code by recursive descent. + +all second pass functions are prefixed with `p2_` + + +### helper functions and utilities + +There are a few common data structures for use within the program to make programming easier: + +- Vectors: dynamic arrays (common functions prefixed with `vect_`) +- Artifacts: representations of delineated strings such as file paths or fully qualified type names (common functions start with `art_`) +- Types: representations of internal and user defined types (common functions prefixed with `type_`) +- Variables: representation of actual variable data within the program. Can be a literal, register, stack, or data based value. Operations can be performed with Variable structs to generate assembly (common functions start with `var_`) +- Modules: representation of tnsl modules which contain Types, global Variables, Functions, and sub Modules (common funcs start with `mod_`) + |
