2011-10-25Add support for the notion of "hidden" relocations. On MachO, these are ↵Owen Anderson
relocation entries that are used as additional information for other, real relocations, rather than being relocations themselves.

2011-10-25Add a few test cases to ensure the bitcode reader is backward compatible withChad Rosier
LLVM 2.9. My understanding is that we plan to maintain compatibility with 2.9 until the 3.1 release. At that time we can generate new test cases using LLVM 3.0. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142958 91177308-0d34-0410-b5e6-96231b3b80d8

2011-10-25Revert commit 142891. Takumi bisected the tablegen miscompilesDuncan Sands
down to this commit. Original commit message: An MBB which branches to an EH landing pad shouldn't be considered for tail merging. In SjLj EH, the jump to the landing pad is not done explicitly through a branch statement. The EH landing pad is added as a successor to the throwing BB. Because of that however, the branch folding pass could mistakenly think that it could merge the throwing BB with another BB. This isn't safe to do. <rdar://problem/10334833> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142920 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-25Restore commits 142790 and 142843 - they weren't breaking the buildDuncan Sands
bots. Original commit messages: - Reapply r142781 with fix. Original message: Enhance SCEV's brute force loop analysis to handle multiple PHI nodes in the loop header when computing the trip count. With this, we now constant evaluate: struct ListNode { const struct ListNode *next; int i; }; static const struct ListNode node1 = {0, 1}; static const struct ListNode node2 = {&node1, 2}; static const struct ListNode node3 = {&node2, 3}; int test() { int sum = 0; for (const struct ListNode *n = &node3; n != 0; n = n->next) sum += n->i; return sum; } - Now that we look at all the header PHIs, we need to consider all the header PHIs when deciding that the loop has stopped evolving. Fixes miscompile in the gcc torture testsuite! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142919 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-25Fix the API usage in loop probability heuristics. It was incorrectlyChandler Carruth
classifying many edges as exiting which were in fact not. These mainly formed edges into sub-loops. It was also not correctly classifying all returning edges out of loops as leaving the loop. With this match most of the loop heuristics are more rational. Several serious regressions on loop-intesive benchmarks like perlbench's loop tests when built with -enable-block-placement are fixed by these updated heuristics. Unfortunately they in turn uncover some other regressions. There are still several improvemenst that should be made to loop heuristics including trip-count, and early back-edge management. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142917 91177308-0d34-0410-b5e6-96231b3b80d8
