3.13 Directive OPTION CODEVIEW
The OPTION CODEVIEW directive allows to fine-tune the generation of symbolic debugging information. It has no effect at all if commandline option -Zi isn't set. Syntax:- OPTION CODEVIEW:switches
There is currently only one switch :
- [bit 0]: If 1, create symbols with indices S_[L|G]THREAD32 instead of S_[L|G]DATA32
for data items that are stored in segments with class 'TLS'. This allows the debugger
to display the correct value of static TLS ( Thread Local Storage ) variables. Example:
option codeview:1 _TLS segment dword alias(".tls") public 'TLS' tvar DD -1 ;codeview symbol tvar will be S_LTHREAD32 _TLS ends
