* Define placement new wrappers for BumpPtrAllocator andDan Gohman2010-03-182-101/+69
| | | | | | | RecyclingAllocator to allow client code to be simpler, and simplify several clients. llvm-svn: 98847
* 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. llvm-svn: 98845

* Revert "Change coalescer complexity from N^2 to N logN by changing one letter."Jakob Stoklund Olesen2010-03-181-1/+12
| | | | | | This reverts commit 98776. It broke the llvm-gcc boot strap. llvm-svn: 98784

* Change coalescer complexity from N^2 to N logN by changing one letter.Jakob Stoklund Olesen2010-03-171-12/+1
| | | | | | | | | Remove ugly hack that aborted the coalescer before using N^2 time. This affects functions with very complicated live intervals for physical registers, i.e. functions with thousands of function calls. llvm-svn: 98776
* Fix EmitSectionOffset incorrect argument. DwarfDebug is emitting debug info ↵Devang Patel2010-03-171-9/+8
| | | | | | so isEH is always false. This was hiding until now from compilers because of default arguments. This was hiding from dwarf debug info users because for most of the platform isAbsoluteEHSectionOffsets() is same as isAbsoluteDebugSectionOffsets(). But Chris found it while updating dwarf printer to use MC*. llvm-svn: 98743

* Fix the third (and last known) case of code update problems due Chris Lattner2010-03-162-28/+122
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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. llvm-svn: 98595
* Now that the default for Darwin platforms is to place the LSDA into the TEXTBill Wendling2010-03-151-3/+3

* Implement support for the case when a reference to a addr-of-bb Chris Lattner2010-03-152-6/+69
| | | | | | | | | label is generated, but then the block is deleted. Since the value is undefined, we just emit the label right after the entry label of the function. It might matter that the label is in the same section as the function was afterall. llvm-svn: 98579
