2013-07-24[MIPS] Fix LLVM merge issuesPetar Jovanovic
Several parts of the already in-place code have been omitted in the previous merge. These are: - missing lowering of Intrinsic::nacl_read_tp; - checks for forbidden instructiosn in branch-delay slots; - lowering operation for ISD::NACL_TP_TLS_OFFSET and ISD::NACL_TP_TDB_OFFSET.

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

2012-10-23[MIPS] Update sandboxing changes for LLVM on MIPS.Petar Jovanovic
This change - resolves conflicts from previous merges; - prevents delay slot filler to use instructions that could be masked; - generates calls to __nacl_read_tp to access thread pointer; - removes previous (now obsolete) sandboxing code of unaligned loads and stores; - propagates relocation model to MipsELFObjectWriter, so that it can set flag ELF::EF_MIPS_PIC (small hack).

delay slot filler pass of MIPS, per suggestion of Jakob Stoklund Olesen. This change, along with the fix in r158154, enables machine verification to be run after delay slot filling. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@158426 91177308-0d34-0410-b5e6-96231b3b80d8

2012-05-14Add a command line option to skip the delay slot filler pass entirely for Mips.Akira Hatanaka
The purpose of this option is to silence error messages issued by machine verifier passes and enable them to run to the end. If this option is not provided, -verify-machineinstrs complains when it discovers there is a non-terminator instruction (an instruction that is in a delay slot) after the first terminator in a basic block. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@156790 91177308-0d34-0410-b5e6-96231b3b80d8

2011-12-07Add bundle aware API for querying instruction properties and switch the codeEvan Cheng
generator to it. For non-bundle instructions, these behave exactly the same as the MC layer API. For properties like mayLoad / mayStore, look into the bundle and if any of the bundled instructions has the property it would return true. For properties like isPredicable, only return true if *all* of the bundled instructions have the property. For properties like canFoldAsLoad, isCompare, conservatively return false for bundles. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@146026 91177308-0d34-0410-b5e6-96231b3b80d8
