2009-09-25Switch ogle to in-tree gosym package. Delete my private symAustin Clements13-1945/+84
package. If a Sym is a function symbol, include a reference to the Func so it's easily accessible when you're traversing the list of all symbols. This diff is more interesting than the proc switch because the gosym interface differs from the old sym interface.

2009-09-01Clean up the statement and expression public interfaces. TheAustin Clements2-40/+29
only visible change is that evaluating an expression returns a interface{} instead of a Value. R=rsc APPROVED=rsc DELTA=60 (15 added, 26 deleted, 19 changed) OCL=34206 CL=34208
2009-09-01Add stack frame support. Architectures are now responsibleAustin Clements5-10/+321
for decoding closures. There is now no notion of a current OS thread, though that needs to come back in the form of a current Go thread. As a result, Process now implements Peek and Poke and maps them to any stopped OS thread, since they all share the address space anyways.

2009-08-27Make the statement compiler not use the AST visitor.Austin Clements3-186/+149
In the process, I made error handling in the statement compiler much saner. Instead of separately tracking various error flags with weird relations, I just track if any error messages have been produced. R=rsc APPROVED=rsc DELTA=308 (98 added, 135 deleted, 75 changed) OCL=33870 CL=33961

2009-08-25Make the expression compiler not use the AST visitor. TheAustin Clements3-497/+502
statement compiler will be fixed in a later CL. The input and output of the expression compiler are now clearly distinguished. In the process, I made the individual expression compilers operate on the compiled form of their children instead of AST nodes. As a result, there are now fewer places where I hand-craft intermediate expression nodes. The diff looks scarier than it is, mostly because exprCompiler has been split into the input and output types, resulting in lots of little renames.
