2012-06-17Make the optimization passes non-recursive.Søren Sandmann Pedersen4-380/+419
Very long functions could cause stack overflow due to peephole() and remove_nops() being recursive.
2012-06-16Optimize away literal nodes followed by to_stringSøren Sandmann Pedersen3-4/+18
2012-06-16Fix bug with switch statements and gotoSøren Sandmann Pedersen3-8/+26
Previously, the condition expression in a switch statement would be generated once, and then each case would do "dup; compare". After the switch, the condition expression would be popped. The problem with this is that if you jump out of the switch, the expression would be left on the stack. So instead generate a temporary variable to hold the condition expression, then load that variable for each case.

2012-06-15Make void functions return a dummy value.Søren Sandmann Pedersen1-4/+18
This means void and non-void functions are called the same way, which means non-void functions can be cast to void functions.

2012-06-15Some formatting fixesSøren Sandmann Pedersen2-31/+15
2012-06-15Fix bug in graph_boolean_expression()Søren Sandmann Pedersen2-3/+11
When the expression is known to be compile-time constant, its value is stored in expr->common.constant_value, but the code was treating the expression as if it were a boolean literal.
2012-06-15Do debug spew from within compile().Søren Sandmann Pedersen3-12/+23
Dump the goto graph after optimization if debug_spew is turned on.
2012-06-15Move levels to its own passSøren Sandmann Pedersen5-20/+79
The optimizer needs to know the embeddeng level of the various definitions. Previously, this was computed in the offsets pass, but if the optimizer removes unused variables, the offsets could change. The levels must be computed before optimizations, but offsets must be computers. So split levels to its own pass that runs before the optimizer.

Then only squash dyn_label + dyn_goto if the label definition is at the same level as the label expression.
