* Fix pr6543: svn r88806 changed MachineJumpTableInfo::getJumpTableIndex() toBob Wilson2010-03-182-6/+14
| | | | | | | | | | | | | | | | | | always create a new jump table. The intention was to avoid merging jump tables in SelectionDAGBuilder, and to wait for the branch folding pass to merge tables. Unfortunately, the same getJumpTableIndex() method is also used to merge tables in branch folding, so as a result of this change branch tables are never merged. Worse, the branch folding code is expecting getJumpTableIndex to always return the index of an existing table, but with this change, it never does so. In at least some cases, e.g., pr6543, this creates references to non-existent tables. I've fixed the problem by adding a new createJumpTableIndex function, which will always create a new table, and I've changed getJumpTableIndex to only look at existing tables. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98845 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | to LLVM IR changes with addr label weirdness. In the testcase, we generate references to the two bb's when codegen'ing the first function: _test1: ## @test1 leaq Ltmp0(%rip), %rax .. leaq Ltmp1(%rip), %rax Then continue to codegen the second function where the blocks get merged. We're now smart enough to emit both labels, producing this code: _test_fun: ## @test_fun ## BB#0: ## %entry Ltmp1: ## Block address taken Ltmp0: ## BB#1: ## %ret movl $-1, %eax ret Rejoice. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98595 91177308-0d34-0410-b5e6-96231b3b80d8
