[Dwarf-discuss] basic_block semantics

[mathieu lacage]

hi,

As usual, I made a fool of myself. After much thinking, I figured out I 
had completely missed the basic idea behind the structure of the dwarf2 
line information. i.e., the fact that it is row-based and that the 
content of each column for each row is precisely defined.

And I will answer my own questions:

It applies whenever a row is created from the registers.

yes.

I suck,
