 // From CMICmnBase

Ilia, I checked string positions for ParseArgs() method in MICmdCmdExec.h and 
other command headers - ParseArgs() placed always third, so this change done in 
accordance with current, at least public, lldb-mi headers and minimal patching 
as possible.

What inconsistency you mentioned ?

Please take a look on ExecRun command class modified with ParseArgs() method 
added and non-modified classes in lldb-mi - ExecFinish or ExecNext, for example:


```
class CMICmdCmdExecRun : public CMICmdBase
{
// Statics:
  public:
// Required by the CMICmdFactory when registering *this command
static CMICmdBase *CreateSelf();

// Methods:

// Overridden:

// From CMICmdInvoker::ICmd
bool Execute() override;
bool Acknowledge() override;
bool ParseArgs() override;
// From CMICmnBase

// Attributes:

lldb::SBCommandReturnObject m_lldbResult;

};
```

Fully agreed.

At same time - this option is relatively new, was not present in older GDBs. 
For example - GDB used in Xcode before switch to lldb just do stop at 
_dyld_start unconditionally always, no option.

Thanks for review, patch will be changed.

You are right, no doubt - this is clear what Target and Process API direct 
usage is faster and straightforward manner.

Just couple words regarding why interpreter used instead here - patch was 
prepared at moment when lldb-MI had lack synchronization (via Listener) with 
lldb Core, so setting corresponding flag gave random results - app may stop or 
not. Via interpreter it worked fine always - that's why I stated "more 
reliable" in review header.

I will check if flag pass is enough currently - this will make patch shorter 
and clearer.

enlight added a subscriber: enlight.
enlight added a comment.

According to the GDB-MI spec the exec-run 

 command already has a **start** option. Support for the **start** option can 
be detected by checking for **exec-run-start-option** in the list of features 
returned by the list-features 

 command. So, what's the rationale for diverging from the spec in this case?

In GDB your example would be written as:
-exec-run --start

The process should be launched through the SB API, not the command interpreter. 
I'm not very familiar with the SB API but I'd try using the 
**lldb::eLaunchFlagStopAtEntry** flag with **SBLaunchInfo::SetLaunchFlags()**.
