2013-01-02Move all of the header files which are involved in modelling the LLVM IRChandler Carruth
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

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

2012-02-27ARM BL/BLX instruction fixups should use relocations.Jim Grosbach
We on the linker to resolve calls to the appropriate BL/BLX instruction to make interworking function correctly. It uses the symbol in the relocation to do that, so we need to be careful about being too clever. To enable this for ARM mode, split the BL/BLX fixup kind off from the unconditional-branch fixups. rdar://10927209 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@151571 91177308-0d34-0410-b5e6-96231b3b80d8

2011-08-03ARM refactoring assembly parsing of memory address operands.Jim Grosbach
Memory operand parsing is a bit haphazzard at the moment, in no small part due to the even more haphazzard representations of memory operands in the .td files. Start cleaning that all up, at least a bit. The addressing modes in the .td files will be being simplified to not be so monolithic, especially with regards to immediate vs. register offsets and post-indexed addressing. addrmode3 is on its way with this patch, for example. This patch is foundational to enable going back to smaller incremental patches for the individual memory referencing instructions themselves. It does just enough to get the basics in place and handle the "make check" regression tests we already have. Follow-up work will be fleshing out the details and adding more robust test cases for the individual instructions, starting with ARM mode and moving from there into Thumb and Thumb2. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136845 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-27ARM parsing and encoding of SBFX and UBFX.Jim Grosbach
Encode the width operand as it encodes in the instruction, which simplifies the disassembler and the encoder, by using the imm1_32 operand def.

2011-07-26ARM cleanup of rot_imm encoding.Jim Grosbach
Start of cleaning this up a bit. First step is to remove the encoder hook by storing the operand as the bits it'll actually encode to so it can just be directly used.

2010-12-14The tLDR et al instructions were emitting either a reg/reg or reg/immBill Wendling
instruction based on the t_addrmode_s# mode and what it returned. There is some obvious badness to this. In particular, it's hard to do MC-encoding when the instruction may change out from underneath you after the t_addrmode_s# variable is finally resolved. The solution is to revert a long-ago change that merged the reg/reg and reg/imm versions. There is the addition of several new addressing modes. They no longer have extraneous operands associated with them. I.e., if it's reg/reg we don't have to have a dummy zero immediate tacked on to the SDNode. There are some obvious cleanups here, which will happen shortly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@121747 91177308-0d34-0410-b5e6-96231b3b80d8
