* Merging r195477:Bill Wendling2013-11-25
| | | | | | | | | | | | | | | | | | | | | | | ------------------------------------------------------------------------ r195477 | rafael | 2013-11-22 09:58:12 -0800 (Fri, 22 Nov 2013) | 13 lines Add a fixed version of r195470 back. The fix is simply to use CurI instead of I when handling aliases to avoid accessing a invalid iterator. original message: Convert linkonce* to weak* instead of strong. Also refactor the logic into a helper function. This is an important improve on mingw where the linker complains about mixed weak and strong symbols. Converting to weak ensures that the symbol is not dropped, but keeps in a comdat, making the linker happy. ------------------------------------------------------------------------ git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_34@195603 91177308-0d34-0410-b5e6-96231b3b80d8

* [tests] Cleanup initialization of test suffixes.Daniel Dunbar2013-08-16
| | | | | | | | | | | | | | | | | - Instead of setting the suffixes in a bunch of places, just set one master list in the top-level config. We now only modify the suffix list in a few suites that have one particular unique suffix (.ml, .mc, .yaml, .td, .py). - Aside from removing the need for a bunch of lit.local.cfg files, this enables 4 tests that were inadvertently being skipped (one in Transforms/BranchFolding, a .s file each in DebugInfo/AArch64 and CodeGen/PowerPC, and one in CodeGen/SI which is now failing and has been XFAILED). - This commit also fixes a bunch of config files to use config.root instead of older copy-pasted code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@188513 91177308-0d34-0410-b5e6-96231b3b80d8
* Use pipefail when available.Rafael Espindola2013-07-26
| | | | | | | | | | | | | | This change makes test with RUN lines like RUN: opt ... | FileCheck fail if opt fails, even if it prints what FileCheck wants.

| | | | | | | | | | | | | | | | | | | The plan is to use it for clang and lld. Major behavior changes: - We can now parse UTF-16 files that have a byte order mark. - PR16209: Don't drop backslashes on the floor if they don't escape anything.

* IR: Don't constant fold GEP bitcasts between different address spacesMeador Inge2013-02-27
| | | | | | | | | | | | | | | | | | PR15262 reported a bug where the following instruction: i8 getelementptr inbounds i8* bitcast ([4 x i8] addrspace(12)* @buf to i8*), i32 2 was getting folded into: addrspace(12)* getelementptr inbounds ([4 x i8] addrspace(12)* @buf, i32 0, i32 2) This caused instcombine to crash because the original instruction and the folded instruction have different types. The issue was fixed by disallowing bitcasts between different address spaces to be folded away. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176156 91177308-0d34-0410-b5e6-96231b3b80d8

* Revert the series of commits starting with r166578 which introduced theChandler Carruth2012-11-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Change the way the lint sanity checking pass detects misaligned memory accesses.Duncan Sands2012-09-25
| | | | | | | | | | | | | | | | Previously it was only be able to detect problems if the pointer was a numerical value (eg inttoptr i32 1 to i32*), but not if it was an alloca or globa. The reason was the use of ComputeMaskedBits: imagine you have "alloca i8, align 2", and ask ComputeMaskedBits what it knows about the bits of the alloca pointer. It can tell you that the bottom bit is known zero (due to align 2) but it can't tell you that bit 1 is known one. That's because the address could be an even multiple of 2 rather than an odd multiple, eg it might be a multiple of 4. Thus trying to use KnownOne is ineffective in the case of an alloca as it will never have any bits set. Instead look explicitly for constant offsets from allocas and globals. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@164595 91177308-0d34-0410-b5e6-96231b3b80d8
