From a244814e6f8a21528e3ff1410a6db2684f5d03ed Mon Sep 17 00:00:00 2001 From: Daniel Dunbar Date: Thu, 23 Jul 2009 03:03:07 +0000 Subject: These IRgen improvements have been done. Technically we could still do a bit more to avoid deferred generation of statics which we know are used, but I seriously doubt this is important. llvm-svn: 76844 --- clang/lib/CodeGen/README.txt | 18 ------------------ 1 file changed, 18 deletions(-) (limited to 'clang/lib/CodeGen/README.txt') diff --git a/clang/lib/CodeGen/README.txt b/clang/lib/CodeGen/README.txt index f60cd03ad64..e6d61095bf2 100644 --- a/clang/lib/CodeGen/README.txt +++ b/clang/lib/CodeGen/README.txt @@ -45,21 +45,3 @@ On 176.gcc:expr.ll, it looks like over 12% of basic blocks are just direct branches! //===---------------------------------------------------------------------===// - -There are some more places where we could avoid generating unreachable code.
