d0f3459efb bugfix, Issue #163: offset of g struct in TLS picked based on the value of runtime.buildVersion and presence of compile units created by GNU AS, instead of being fixed to -16 2015-07-28 07:33:51 +02:00

3cee10d8bc Implement 'trace' subcommand 
Allows a user to execute `dlv trace [regexp]` and Delve will execute the
program and output information on functions matching [regexp].

4d88d9ed8d Prefer binary search over tree lookup for FDEs 
FDEs previously were loaded into a red/black tree and searched. This is
significantly more expensive than a binary search over a slice. Not sure
what I was thinking using a red/black tree - this binary search
implementation is significantly more efficient.

3b2b17938b Improve support for goroutine context switching 
Remove any assumption that a wait syscall on a thread id after a
continue will return. Any time we continue a thread, wait for activity
from any thread, because the scheduler may well have switched contexts
on us due to syscall entrace, channel op, etc...

There are several more things to be done here including:

* Potential tracking of goroutine id as we jump around to thread
  contexts.
* Potential of selectively choosing threads to operate on based on the
  internal M data structures, ensuring that our M has an active G.

This commit partially fixes #23 and #24, however there are still some
random hangs that happen and need to be ironed out.

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/*.
