* misched: Heuristics based on the machine model.Andrew Trick2012-11-07
| | | | | | | | | | | | | | misched is disabled by default. With -enable-misched, these heuristics balance the schedule to simultaneously avoid saturating processor resources, expose ILP, and minimize register pressure. I've been analyzing the performance of these heuristics on everything in the llvm test suite in addition to a few other benchmarks. I would like each heuristic check to be verified by a unit test, but I'm still trying to figure out the best way to do that. The heuristics are still in considerable flux, but as they are refined we should be rigorous about unit testing the improvements. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167527 91177308-0d34-0410-b5e6-96231b3b80d8

* Add a method to indicate section address re-assignment is finished.Andrew Kaylor2012-11-05
| | | | | | Prior to this patch RuntimeDyld attempted to re-apply relocations every time reassignSectionAddress was called (via MCJIT::mapSectionAddress). In addition to being inefficient and redundant, this led to a problem when a section was temporarily moved too far away from another section with a relative relocation referencing the section being moved. To fix this, I'm adding a new method (finalizeObject) which the client can call to indicate that it is finished rearranging section addresses so the relocations can safely be applied. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167400 91177308-0d34-0410-b5e6-96231b3b80d8
* On PowerPC64, integer return values (as well as arguments) are supposedUlrich Weigand2012-11-05
| | | | | | | | | | | | | | | | | | | | | | | | | | to be extended to a full register. This is modeled in the IR by marking the return value (or argument) with a signext or zeroext attribute. However, while these attributes are respected for function arguments, they are currently ignored for function return values by the PowerPC back-end. This patch updates PPCCallingConv.td to ask for the promotion to i64, and fixes LowerReturn and LowerCallResult to implement it. The new test case verifies that both arguments and return values are properly extended when passing them; and also that the optimizers understand incoming argument and return values are in fact guaranteed by the ABI to be extended. The patch caused a spurious breakage in CodeGen/PowerPC/coalesce-ext.ll, since the test case used a "ret" instruction to create a use of an i32 value at the end of the function (to set up data flow as required for what the test is intended to test). Since there's now an implicit promotion to i64, that data flow no longer works as expected. To fix this, this patch now adds an extra "add" to ensure we have an appropriate use of the i32 value. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167396 91177308-0d34-0410-b5e6-96231b3b80d8

* Add support for the PowerPC-specific inline asm Z constraint and y modifier.Hal Finkel2012-11-05
| | | | | | | | | | The Z constraint specifies an r+r memory address, and the y modifier expands to the "r, r" in the asm string. For this initial implementation, the base register is forced to r0 (which has the special meaning of 0 for r+r addressing on PowerPC) and the full address is taken in the second register. In the future, this should be improved. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167388 91177308-0d34-0410-b5e6-96231b3b80d8

* Fix the IntegersSubsetTest unit test when compiled with gcc-4.7. The issue hereDuncan Sands2012-11-03
| | | | | | | | | | | | is that the unit test doesn't have IntTy equal to APInt, instead it uses a class derived from APInt. When, as in these lines, an IntTy& reference is returned but is assigned to an APInt&, the compiler destroys the temporary the IntTy& was referring to, leaving the APInt& referring to garbage. This causes the unittest to fail systematically on my machine; it can also be caught by running the test under valgrind. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167356 91177308-0d34-0410-b5e6-96231b3b80d8
