Bug ID: 19402
Summary: Finish converting instcombine to use IRBuilder
Product: libraries
Version: trunk
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P
Component: Scalar Optimizations
Assignee: [email protected]
Reporter: [email protected]

Classification: Unclassified
Instcombine got an IR builder in r80492, but the move is still not done. Right
now a we have a mix of visit methods doing
Foo = Builder->CreateFoo()...
return ReplaceInstUsesWith(I, Foo);
or just
return new Foo(...);
and letting the main loop insert the instruction in the BB and replace it.
Using the builder looks like the new way, but it seems to be missing some
features, like reusing the old instruction name.
