944c200a5d Initial support of try as expression in JVM IR 2019-04-08 13:10:24 +02:00

ef5e02da84 JVM_IR: handle Nothing and Unit more consistently.
* In blocks, discard the result of any statement that has a return
   type other than void. This was previously done by wrapping each
   statement into an "implicit Unit conversion" that was actually
   compiled down to a stack pop instead. If an expression happened to
   already have type Unit, however, such a conversion was not inserted,
   resulting in a stray reference on the stack. These conversions are
   now redundant and should probably be removed.

 * In assignments and non-exhaustive conditionals, materialize a Unit
   on the stack to avoid depth mismatches that trip up the bytecode
   validator. Because such expressions are generally used at block level
   (and, indeed, the frontend will reject a non-exhaustive conditional
   used as an expression), combined with the above change this results
   in no additional GETSTATIC opcodes, as they are immediately removed
   by the peephole optimizer.

620143ae5b Add test on bytecode text
Test data should be a Kotlin source file with zero or more comments e.g. of
the form: '// 1 INVOKEVIRTUAL'. The test then checks that the generated
bytecode for this file contains exactly one occurrence of the string
'INVOKEVIRTUAL'
