We want heuristics to be based on accurate data, but more importantly
we don't want llvm to behave randomly. A benign trunc inserted by an
upstream pass should not cause a wild swings in optimization
level. See PR11034. It's a general problem with threshold-based
heuristics, but we can make it less bad.

Stop emitting instructions with the name "tmp" they eat up memory and have to be uniqued, without any benefit.2011-09-27T20:39:19ZBenjamin Kramerbenny.kra@googlemail.com2011-09-27T20:39:19Zurn:sha1:a9390a4d5f5d568059a80970d22194b165d097a7
If someone prefers %tmp42 to %42, run instnamer.

Place the check for an exit landing pad where it will be run on both code paths through the if-then-else.2011-09-20T22:27:16ZBill Wendlingisanbard@gmail.com2011-09-20T22:27:16Zurn:sha1:b7e807f9a9a74d743547856c4275a320f7b5b15e

Omit extracting a loop if one of the exits is a landing pad.2011-09-20T22:23:09ZBill Wendlingisanbard@gmail.com2011-09-20T22:23:09Zurn:sha1:84b6706d9003f6078a81ed7d84f4e49ee70f7ef8
The landing pad must accompany the invoke when it's extracted. However, if it
does, then the loop isn't properly extracted. I.e., the resulting extraction has
a loop in it. The extracted function is then extracted, etc. resulting in an
infinite loop.

When extracting a basic block that ends in an 'invoke' instruction, we need to2011-09-20T19:10:24ZBill Wendlingisanbard@gmail.com2011-09-20T19:10:24Zurn:sha1:2f1cd85598d260e5567804460e87f8bee0c5e1e5
extract its associated landing pad block as well. However, that landing pad
block may have more than one predecessor. So split the landing pad block so that
individual landing pads have only one predecessor.
This type of transformation may produce a false positive with bugpoint.

Add a mechanism for optimisation plugins to register passes that all front ends can use without needing to be aware of the plugin (or the plugin be aware of the front end).2011-08-16T13:58:41ZDavid Chisnallcsdavec@swan.ac.uk2011-08-16T13:58:41Zurn:sha1:7a817eae6cb00a2ba5ec2a4127775b839a357e4c
Before 3.0, I'd like to add a mechanism for automatically loading a set of plugins from a config file. API suggestions welcome...
