248766300d Remove silly function 2014-10-13 08:27:25 -05:00

dc8c9cc2a4 Optimize Next implementation 
Once the program detects that we have stepped into another function,
we simply calculate the return address and then set a breakpoint and
continue to that location, avoiding numerous syscalls.

c9cbaea291 Optimize Next implementation 
Now that I'm using the step strategy, I put in an optimization where if
stepping into another function, simply find the return address, put a
breakpoint there, and then continue.

f1e5a70a4b Update for Go 1.3.1 
I decided to vendor all debug/dwarf and debug/elf files so that the
project can be go get-table. All changes that I am waiting to land in Go
1.4 are now captured in /vendor/debug/*.

3566fd5237 Improve next implementation 
Improvements:
* `next`ing through a loop works correctly (when not already within a loop)
* `next`ing out of a function works correctly

Needs work:
* `next`ing in a loop can be improved when starting within a loop

a788e03c7b Implement initial next implementation 
This current implementation does not cover the following:

* Setting correct breakpoint when exiting loop
* Setting correct breakpoint when returning from function
    * All facilities are available for this, it just is not taken into
      account in the current `next` implementation.
