Nuno Lopes	23e75da7e0	revert my previous patches that introduced an additional parameter to the objectsize intrinsic. ... After a lot of discussion, we realized it's not the best option for run-time bounds checking git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157255 91177308-0d34-0410-b5e6-96231b3b80d8	2012-05-22 15:25:31 +00:00
Nuno Lopes	30759542aa	change the objectsize intrinsic signature: add a 3rd parameter to denote the maximum runtime performance penalty that the user is willing to accept. ... This commit only adds the parameter. Code taking advantage of it will follow. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@156473 91177308-0d34-0410-b5e6-96231b3b80d8	2012-05-09 15:52:43 +00:00
Bill Wendling	e3e394d982	Do trivial CSE of dead BBs during codegen preparation. ... Some BBs can become dead after codegen preparation. If we delete them here, it could help enable tail-call optimizations later on. <rdar://problem/10256573> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@152002 91177308-0d34-0410-b5e6-96231b3b80d8	2012-03-04 10:46:01 +00:00
Cameron Zwarich	53aac15a60	Fix the GCC test suite issue exposed by r127477, which was caused by stack ... protector insertion not working correctly with unreachable code. Since that revision was rolled out, this test doesn't actual fail before this fix. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@127497 91177308-0d34-0410-b5e6-96231b3b80d8	2011-03-11 21:51:56 +00:00
