* Update aosp/master LLVM for rebase to r235153Pirama Arumuga Nainar2015-05-181-0/+17
| | | | | Change-Id: I9bf53792f9fc30570e81a8d80d296c681d005ea7 (cherry picked from commit 0c7f116bb6950ef819323d855415b2f2b0aad987)

* Move all of the header files which are involved in modelling the LLVM IRChandler Carruth2013-01-021-2/+2
| | | | | | | | | | | | | | | | | | | | | into their new header subdirectory: include/llvm/IR. This matches the directory structure of lib, and begins to correct a long standing point of file layout clutter in LLVM. There are still more header files to move here, but I wanted to handle them in separate commits to make tracking what files make sense at each layer easier. The only really questionable files here are the target intrinsic tablegen files. But that's a battle I'd rather not fight today. I've updated both CMake and Makefile build systems (I think, and my tests think, but I may have missed something). I've also re-sorted the includes throughout the project. I'll be committing updates to Clang, DragonEgg, and Polly momentarily. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171366 91177308-0d34-0410-b5e6-96231b3b80d8
* Use the new script to sort the includes of every file under lib.Chandler Carruth2012-12-031-3/+3
| | | | | | | | | | | | | | | | | 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

| | | | | | | | | | The long branch pass (fixed in r160601) no longer uses the global base register to compute addresses of branch destinations, so it is not necessary to reserve a slot on the stack. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@160703 91177308-0d34-0410-b5e6-96231b3b80d8

Directives ".set noat" and ".set at" are now emitted only at the beginning and end of a function except in the case where they are emitted to enclose .cpload with an immediate operand that doesn't fit in 16-bit field or unaligned load/stores. Also, make the following changes: - Remove function isUnalignedLoadStore and use a switch-case statement to determine whether an instruction is an unaligned load or store. - Define helper function CreateMCInst which generates an instance of an MCInst from an opcode and a list of operands. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@153552 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | The following improvements are accomplished as a result of applying this patch: - Fixed frame objects' offsets (relative to either the virtual frame pointer or the stack pointer) are set before instruction selection is completed. There is no need to wait until Prologue/Epilogue Insertion is run to set them. - Calculation of final offsets of fixed frame objects is straightforward. It is no longer necessary to assign negative offsets to fixed objects for incoming arguments in order to distinguish them from the others. - Since a fixed object has its relative offset set during instruction selection, there is no need to conservatively set its alignment to 4. - It is no longer necessary to reorder non-fixed frame objects in MipsFrameLowering::adjustMipsStackFrame. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@131915 91177308-0d34-0410-b5e6-96231b3b80d8
