[lldb-dev] New linux process plugin

[Stephen Wilson]

Hi all,

I just pushed the new linux process plugin.  A few notes:

I updated the makefiles to build only under linux.  I do not know if
this will build on a mac.  Perhaps someone can try and let me know the
result.

Only very basic breakpoint/step-over functionality is present.  For
example, we cannot resolve pending breakpoints yet, so one must set
breakpoints with the debugee stopped on entry.

Only x86_64 at the moment (will add i386 soon).

Here is a simple example of what is working for those who might like to
test it out:

===--------------------------------------------------------------------------===
 > cat ctest.c

   void foo() { return; }

   void bar() { return; }

   int main()
   {
       foo();
       bar();
       return 0;
   }

 > lldb ./ctest
   Current executable set to './ctest' (x86_64).

   Breakpoint created: 1: name = 'foo', locations = 1, resolved = 1
   (lldb) b s -n bar
   Breakpoint created: 2: name = 'bar', locations = 1, resolved = 1
   (lldb) p c

      1         
      2 ->      void foo() { return; }
      3         
      4         void bar() { return; }
      5         
   (lldb) p c
   Resuming process 0
   (lldb) Process 0 Stopped
   * thread #1: tid = 0x4789, pc = 0x000000000040047e, ...

      2         void foo() { return; }
      3         
      4 ->      void bar() { return; }
      5         
      6         int main()
      7         {
   (lldb) q

It's a start.  Let be know of any issues, comments, advice, etc.

Thanks!
