Isaac Freund	f9963909a1	stage2/wasm: only free types after func overwrite ... Functions which are free'd are not immediately removed from the binary as this would cause a shifting of function indexes. Instead, they hang around until they can be overwritten by a new function. This means that the types associated with these dead functions must also remain until the function is overwritten to avoid a type mismatch.	2020-08-18 01:01:13 +02:00
Isaac Freund	60fb50ee5a	stage2/wasm: write exports on flush, cleanup ... Exports now have a dirty flag and are rewritten on flush if this flag has been set. A couple other minor changes have been made based on Andrew's review.	2020-08-18 01:01:13 +02:00
Isaac Freund	3370b5f109	stage2/wasm: implement basic container generation ... Thus far, we only generate the type, function, export, and code sections. These are sufficient to generate and export simple functions. Codegen is currently hardcoded to `i32.const 42`, the main goal of this commit is to create infrastructure for the container format which will work with incremental compilation.	2020-08-18 00:32:58 +02:00
