2012-11-14X86: Enable SSE memory intrinsics even when stack alignment is less than 16 ↵Benjamin Kramer
bytes. The stack realignment code was fixed to work when there is stack realignment and a dynamic alloca is present so this shouldn't cause correctness issues anymore. Note that this also enables generation of AVX instructions for memset under the assumptions: - Unaligned loads/stores are always fast on CPUs supporting AVX - AVX is not slower than SSE We may need some tweaked heuristics if one of those assumptions turns out not to be true. Effectively reverts r58317. Part of PR2962. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167967 91177308-0d34-0410-b5e6-96231b3b80d8

2012-11-08Add @nacl.read.tp() intrinsic, a fast version of NaCl's tls_get() IRT interfaceMark Seaborn
This is in preparation for adding an LLVM pass that will expand out TLS (thread_local) variable accesses into calls to nacl.read.tp. On ARM, there is already an arm.thread.pointer intrinsic. We reuse the code for that. On x86, we have to add an implementation. The added code is based on x86's LowerToTLSExecModel() for the %gs:0 case, and on NaCl-MIPS' LowerGlobalTLSAddress() for the __nacl_read_tp() case. (In contrast, X86NaClRewritePass.cpp inserts a __nacl_read_tp() call at the lower MI level; we don't use that approach here.) We convert LowerINTRINSIC_WO_CHAIN() into a method in order to access the Subtarget member. This is consistent with other x86 Lower methods and with the ARM version.

The problem is that we are using ESP as the stack pointer in X86ISelLowering and RSP as the stack pointer in X86FrameLowering, and that revision made them both consistently use X86RegisterInfo to determine which to use.

2012-11-01Revert the majority of the next patch in the address space series:Chandler Carruth
r165941: Resubmit the changes to llvm core to update the functions to support different pointer sizes on a per address space basis. Despite this commit log, this change primarily changed stuff outside of VMCore, and those changes do not carry any tests for correctness (or even plausibility), and we have consistently found questionable or flat out incorrect cases in these changes. Most of them are probably correct, but we need to devise a system that makes it more clear when we have handled the address space concerns correctly, and ideally each pass that gets updated would receive an accompanying test case that exercises that pass specificaly w.r.t. alternate address spaces. However, from this commit, I have retained the new C API entry points. Those were an orthogonal change that probably should have been split apart, but they seem entirely good. In several places the changes were very obvious cleanups with no actual multiple address space code added; these I have not reverted when I spotted them. In a few other places there were merge conflicts due to a cleaner solution being implemented later, often not using address spaces at all. In those cases, I've preserved the new code which isn't address space dependent. This is part of my ongoing effort to clean out the partial address space code which carries high risk and low test coverage, and not likely to be finished before the 3.2 release looms closer. Duncan and I would both like to see the above issues addressed before we return to these changes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167222 91177308-0d34-0410-b5e6-96231b3b80d8
2012-11-01Revert the series of commits starting with r166578 which introduced theChandler Carruth
getIntPtrType support for multiple address spaces via a pointer type, and also introduced a crasher bug in the constant folder reported in PR14233. These commits also contained several problems that should really be addressed before they are re-committed. I have avoided reverting various cleanups to the DataLayout APIs that are reasonable to have moving forward in order to reduce the amount of churn, and minimize the number of commits that were reverted. I've also manually updated merge conflicts and manually arranged for the getIntPtrType function to stay in DataLayout and to be defined in a plausible way after this revert. Thanks to Duncan for working through this exact strategy with me, and Nick Lewycky for tracking down the really annoying crasher this triggered. (Test case to follow in its own commit.) After discussing with Duncan extensively, and based on a note from Micah, I'm going to continue to back out some more of the more problematic patches in this series in order to ensure we go into the LLVM 3.2 branch with a reasonable story here. I'll send a note to llvmdev explaining what's going on and why. Summary of reverted revisions: r166634: Fix a compiler warning with an unused variable. r166607: Add some cleanup to the DataLayout changes requested by Chandler. r166596: Revert "Back out r166591, not sure why this made it through since I cancelled the command.
