2012-12-03Use the new script to sort the includes of every file under lib.Chandler Carruth
Sooooo many of these had incorrect or strange main module includes. I have manually inspected all of these, and fixed the main module include to be the nearest plausible thing I could find. If you own or care about any of these source files, I encourage you to take some time and check that these edits were sensible. I can't have broken anything (I strictly added headers, and reordered them, never removed), but they may not be the headers you'd really like to identify as containing the API being implemented. Many forward declarations and missing includes were added to a header files to allow them to parse cleanly when included first. The main module rule does in fact have its merits. =] git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169131 91177308-0d34-0410-b5e6-96231b3b80d8
2012-11-30Codegen failure for vmull with small vectorsSebastian Pop
Codegen was failing with an assertion because of unexpected vector operands when legalizing the selection DAG for a MUL instruction. The asserting code was legalizing multiplies for vectors of size 128 bits. It uses a custom lowering to try and detect cases where it can use a VMULL instruction instead of a VMOVL + VMUL. The code was looking for input operands to the MUL that had been sign or zero extended. If it found the extended operands it would drop the sign/zero extension and use the original vector size as input to a VMULL instruction. The code assumed that the original input vector was 64 bits so that after dropping the extension it would fit directly into a D register and could be used as an operand of a VMULL instruction. The input code that trigger the failure used a vector of <4 x i8> that was sign extended to <4 x i32>. It was not safe to drop the sign extension in this case because the original vector is only 32 bits wide. The fix is to insert a sign extension for the vector to reach the required 64 bit size. In this particular example, the vector would need to be sign extented to a <4 x i16>. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169024 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.
