`wback` subset01 implementation #11

Closed poorna2152 closed 2 years ago

poorna2152 commented 2 years ago

Following tests are failing at the moment,

assign8-v.bal: This has an int array. Not sure whether arrays are in subset01.
add2-p.bal, div1-p.bal, div3-p.bal, rem1-p.bal: These tests are failing since they are throwing exceptions and exception handling is not implemented in from the WASM side yet.
rel-v.bal: This test fails due to it calling println function with a i32(boolean) value than a i64 which it expects.

Just for the record: assign8-v.bal and rel-v.bal are there in the subset 1 by a mistake.

Need to fix p cases by throwing an exception. Any function that blows up wasm execution should work, no need to wait for exceptions proposal form wasm.

equal-v.bal failing: function return type set to any in this testcase and calls printlnwith boolean

Expression record type holds an array of tokens instead of a string. This tokens are later joined in creating the wat file. The sub types of Expression WasmBlock, WasmLoop, If and Break in the previous code were removed.
