Hi,
It has been a long time since I noticed the whirl tree dumped.
There are usually two "blank" block at the beginning of a function. Like:
FUNC_ENTRY
BODY
BLOCK
END_BLOCK
BLOCK
END_BLOCK
PRAGMA 0 120 <null-st> 0 (0x0) #PREAMBLE_END
What is the function of the two blank blocks and the concept of
preamble? Thanks.
