Rafael Espindola	7749d7ccc7	Handle calls and invokes in GlobalStatus. This patch teaches GlobalStatus to analyze a call that uses the global value as a callee, not as an argument. With this change internalize call handle the common use of linkonce_odr functions. This reduces the number of linkonce_odr functions in a LTO build of clang (checked with the emit-llvm gold plugin option) from 1730 to 60. llvm-svn: 193436	2013-10-25 21:29:52 +00:00
Rafael Espindola	3d7fc25c7c	Optimize more linkonce_odr values during LTO. When a linkonce_odr value that is on the dso list is not unnamed_addr we can still look to see if anything is actually using its address. If not, it is safe to hide it. This patch implements that by moving GlobalStatus to Transforms/Utils and using it in Internalize. llvm-svn: 193090	2013-10-21 17:14:55 +00:00

Handle calls and invokes in GlobalStatus.

This patch teaches GlobalStatus to analyze a call that uses the global value as
a callee, not as an argument.

With this change internalize call handle the common use of linkonce_odr
functions. This reduces the number of linkonce_odr functions in a LTO build of
clang (checked with the emit-llvm gold plugin option) from 1730 to 60.
