Duncan Sands b4c8b2d9fa Inlining often produces landingpad instructions with repeated ... catch or repeated filter clauses. Teach instcombine a bunch of tricks for simplifying landingpad clauses. Currently the code only recognizes the GNU C++ and Ada personality functions, but that doesn't stop it doing a bunch of "generic" transforms which are hopefully fine for any real-world personality function. If these "generic" transforms turn out not to be generic, they can always be conditioned on the personality function. Probably someone should add the ObjC++ personality function. I didn't as I don't know anything about it. llvm-svn: 140852		2011-09-30 13:12:16 +00:00

Instrumentation	If simple ownership works then friendship is not required.	2011-09-20 18:48:56 +00:00
IPO	Stop emitting instructions with the name "tmp" they eat up memory and have to be uniqued, without any benefit.	2011-09-27 20:39:19 +00:00
Scalar	Fold two identical set lookups into one. No functionality change.	2011-09-29 23:40:12 +00:00
Utils	Clean up uses of switch instructions so they are not dependent on the operand ordering. Patch by Stepan Dyatkovskiy.	2011-09-29 20:21:17 +00:00
CMakeLists.txt	Move library stuff out of the toplevel CMakeLists.txt file.	2011-02-18 22:06:14 +00:00
