Nick Lewycky 4a3935c27e A dead malloc, a free(NULL) and a free(undef) are all trivially dead ... instructions. This doesn't introduce any optimizations we weren't doing before (except potentially due to pass ordering issues), now passes will eliminate them sooner as part of their own cleanups. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142787 91177308-0d34-0410-b5e6-96231b3b80d8		2011-10-24 04:35:36 +00:00

Hello	Since the Hello pass is built as a loadable dynamic library, don't try to convert it to new-style registration yet.	2010-10-07 00:31:16 +00:00
InstCombine	Minor simplification: use ShuffleVectorInst::getMaskValue instead of a more expensive helper.	2011-10-21 19:11:34 +00:00
Instrumentation	If simple ownership works then friendship is not required.	2011-09-20 18:48:56 +00:00
IPO	Refactor code from inlining and globalopt that checks whether a function definition is unused, and enhance it so it can tell that functions which are only used by a blockaddress are in fact dead. This probably doesn't happen much on most code, but the Linux kernel's _THIS_IP_ can trigger this issue with blockaddress. (GlobalDCE can also handle the given tescase, but we only run that at -O3.) Found while looking at PR11180.	2011-10-20 05:23:42 +00:00
Scalar	The element insertion code in scalar replacement doesn't handle incorrect	2011-10-23 07:02:10 +00:00
Utils	A dead malloc, a free(NULL) and a free(undef) are all trivially dead	2011-10-24 04:35:36 +00:00
CMakeLists.txt	Move library stuff out of the toplevel CMakeLists.txt file.	2011-02-18 22:06:14 +00:00
Makefile	Revert r100896 and around - this breaks the only mingw32 buildbot we have.	2010-04-15 19:51:42 +00:00
