[LLVMdev] dominator, post-dominator and memory leak
...and inserting a free into the predecessors
of dominance frontier of malloc block and it caused double free. It is
possible for multiple free's to be inserted on the path from malloc to an
exit. For example, in the following CFG:
BB10 (malloc)
/ \
BB11 BB12
... / \ / \ ...
\ / \ / \ /
BB13 BB14 BB15

BB16
The block BB10 dominates BB11, BB12 and BB14. The dominance frontier of
BB10 cont...

[LLVMdev] dominator, post-dominator and memory leak
Try breaking the critical edges (-break-crit-edges).
This way, a new block will be created between BB13 and BB11 (call this
BB11.break) and BB15 and BB12 (call this BB12.break).
The predecessors of the dominance frontier will, thus, be BB11.break,
BB12.break, and BB14.
When we enter through a block with a call to malloc(), we will end up in
one of the blocks in the dominance frontier (kind of). These blocks...

How to get all possible combinations?
Dear all, suppose I have a vector with elements as:
Vec <- c(2,3,4,5,6)
Now I want to have all possible combination of length 3 using those
elements and without any repetition. Like, I want to have 1
possibility like 2-3-4 but not 3-2-4.
Can somebody guide me how to achieve that in R?
Thanks for your help.
