| | | | | | | | | | | This patch adds the target analysis passes (usually TargetTransformInfo) to the codgen pipeline. We also expose now the AddAnalysisPasses method through the C API, because the optimizer passes would also benefit from better target-specific cost models.

| | | | | | | | | | | | Implement the getUnrollingPreferences() function for AMDGPUTargetTransformInfo so that loops that do address calculations on pointers derived from alloca are unconditionally unrolled. Unrolling these loops makes it more likely that SROA will be able to eliminate the allocas, which is a big win for R600 since memory allocated by alloca (private memory) is really slow. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@199916 91177308-0d34-0410-b5e6-96231b3b80d8

* R600: Recommit 199842: Add work-around for the CF stack entry HW bugTom Stellard2014-01-23
| | | | | | | | | | | | | | | | | | | The unit test is now disabled on non-asserts builds. The CF stack can be corrupted if you use CF_ALU_PUSH_BEFORE, CF_ALU_ELSE_AFTER, CF_ALU_BREAK, or CF_ALU_CONTINUE when the number of sub-entries on the stack is greater than or equal to the stack entry size and sub-entries modulo 4 is either 0 or 3 (on cedar the bug is present when number of sub-entries module 8 is either 7 or 0) We choose to be conservative and always apply the work-around when the number of sub-enries is greater than or equal to the stack entry size, so that we can safely over-allocate the stack when we are unsure of the stack allocation rules. reviewed-by: Vincent Lejeune <vljn at ovi.com> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@199905 91177308-0d34-0410-b5e6-96231b3b80d8

* ARM: use litpools for normal i32 imms when compiling minsize.Tim Northover2014-01-23
| | | | | | | | | With constant-sharing, litpool loads consume 4 + N*2 bytes of code, but movw/movt pairs consume 8*N. This means litpools are better than movw/movt even with just one use. Other materialisation strategies can still be better though, so the logic is a little odd. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@199891 91177308-0d34-0410-b5e6-96231b3b80d8

* [LPM] Make LoopSimplify no longer a LoopPass and instead both a utilityChandler Carruth2014-01-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | function and a FunctionPass. This has many benefits. The motivating use case was to be able to compute function analysis passes *after* running LoopSimplify (to avoid invalidating them) and then to run other passes which require LoopSimplify. Specifically passes like unrolling and vectorization are critical to wire up to BranchProbabilityInfo and BlockFrequencyInfo so that they can be profile aware. For the LoopVectorize pass the only things in the way are LoopSimplify and LCSSA. This fixes LoopSimplify and LCSSA is next on my list. There are also a bunch of other benefits of doing this: - It is now very feasible to make more passes *preserve* LoopSimplify because they can simply run it after changing a loop. Because subsequence passes can assume LoopSimplify is preserved we can reduce the runs of this pass to the times when we actually mutate a loop structure. - The new pass manager should be able to more easily support loop passes factored in this way. - We can at long, long last observe that LoopSimplify is preserved across SCEV. This *halves* the number of times we run LoopSimplify!!! Now, getting here wasn't trivial. First off, the interfaces used by LoopSimplify are all over the map regarding how analysis are updated. We end up with weird "pass" parameters as a consequence. I'll try to clean at least some of this up later -- I'll have to have it all clean for the new pass manager. Next up I discovered a really frustrating bug. LoopUnroll *claims* to preserve LoopSimplify. That's actually a lie. But the way the LoopPassManager ends up running the passes, it always ran LoopSimplify on the unrolled-into loop, rectifying this oversight before any verification could kick in and point out that in fact nothing was preserved. So I've added code to the unroller to *actually* simplify the surrounding loop when it succeeds at unrolling. The only functional change in the test suite is that we now catch a case that was previously missed because SCEV and other loop transforms see their containing loops as simplified and thus don't miss some opportunities. One test case has been converted to check that we catch this case rather than checking that we miss it but at least don't get the wrong answer. Note that I have #if-ed out all of the verification logic in LoopSimplify! This is a temporary workaround while extracting these bits from the LoopPassManager. Currently, there is no way to have a pass in the LoopPassManager which preserves LoopSimplify along with one which does not. The LPM will try to verify on each loop in the nest that LoopSimplify holds but the now-Function-pass cannot distinguish what loop is being verified and so must try to verify all of them. The inner most loop is clearly no longer simplified as there is a pass which didn't even *attempt* to preserve it. =/ Once I get LCSSA out (and maybe LoopVectorize and some other fixes) I'll be able to re-enable this check and catch any places where we are still failing to preserve LoopSimplify. If this causes problems I can back this out and try to commit *all* of this at once, but so far this seems to work and allow much more incremental progress. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@199884 91177308-0d34-0410-b5e6-96231b3b80d8

* Fix inline assembly that switches between ARM and Thumb modesGreg Fitzgerald2014-01-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch restores the ARM mode if the user's inline assembly does not. In the object streamer, it ensures that instructions following the inline assembly are encoded correctly and that correct mapping symbols are emitted. For the asm streamer, it emits a .arm or .thumb directive. This patch does not ensure that the inline assembly contains the ADR instruction to switch modes at runtime. The problem we need to solve is code like this: int foo(int a, int b) { int r = a + b; asm volatile( ".align 2 \n" ".arm \n" "add r0,r0,r0 \n" : : "r"(r)); return r+1; } If we compile this function in thumb mode then the inline assembly will switch to arm mode. We need to make sure that we switch back to thumb mode after emitting the inline assembly or we will incorrectly encode the instructions that follow (i.e. the assembly instructions for return r+1).
