Fix possible infinite loop in shrink wrapping when searching for save/restore

There is an infinite loop that can occur in Shrink Wrapping while searching
for the Save/Restore points.

Part of this search checks whether the save/restore points are located in
different loop nests and if so, uses the (post) dominator trees to find the
immediate (post) dominator blocks. However, if the current block does not have
any immediate (post) dominators then this search will result in an infinite
loop. This can occur in code containing an infinite loop.

The modification checks whether the immediate (post) dominator is different from
the current save/restore block. If it is not, then the search terminates and the
current location is not considered as a valid save/restore point for shrink wrapping.

7 years agoThis patch changes the interface to enable the shrink wrapping optimization.
Kit Barton [Thu, 6 Aug 2015 18:02:53 +0000 (18:02 +0000)]
This patch changes the interface to enable the shrink wrapping optimization.

It adds a new constructor, which takes a std::function predicate function that
is run at the beginning of shrink wrapping to determine whether the optimization
should run on the given machine function. The std::function can be overridden by
each target, allowing target-specific decisions to be made on each machine

This is necessary for PowerPC, as the decision to run shrink wrapping is
partially based on the ABI. Futhermore, this operates nicely with the GCC iFunc
capability, which allows option overrides on a per-function basis.
