Synopsis: Thumb compilation produces no DWARF FDE instructions
State-Changed-From-To: open->analyzed
State-Changed-By: rearnsha
State-Changed-When: Wed Apr 24 06:09:40 2002
State-Changed-Why:
Confirmed. The Thumb prologue expansion code does not annotate
the prologue instructions to inform the debug table generator
that they are related to the frame creation. A further problem
is that not all of the prologue is expanded into RTL (it's
written directly to the assembly file); this will have to be
rectified before the dwarf annotations will be correct.

Hi,
One thing I noticed as well is that GCC does not produce a lot of FDE
instructions other than those for the prologue. Is this the way GCC
operates?
