* Move DataLayout back to the TargetMachine from TargetSubtargetInfoEric Christopher2015-01-261-2/+2
| | | | | | | | | | | | | | | | | | | derived classes. Since global data alignment, layout, and mangling is often based on the DataLayout, move it to the TargetMachine. This ensures that global data is going to be layed out and mangled consistently if the subtarget changes on a per function basis. Prior to this all targets(*) have had subtarget dependent code moved out and onto the TargetMachine. *One target hasn't been migrated as part of this change: R600. The R600 port has, as a subtarget feature, the size of pointers and this affects global data layout. I've currently hacked in a FIXME to enable progress, but the port needs to be updated to either pass the 64-bitness to the TargetMachine, or fix the DataLayout to avoid subtarget dependent features. llvm-svn: 227113

* [emacs] llvm-mode: fix parens, font-lock i*Ramkumar Ramachandra2015-01-231-10/+3
| | | | | | | | | | | | | | | | In llvm-mode, with electric-pair-mode turned on, typing a literal '[' would print out '[[', and '(' would print a '(('. This was a very annoying bug caused by overzealous syntax-table entries: the parens are already part of the '(' and ')' class by default. Fix this. While at it, notice that i32, i64, i1 etc. are not font-locked despite a clear intent to do so. The issue is that regexp-opt doesn't accept regular expressions. So, spell out the common literal integers with different widths. Differential Revision: http://reviews.llvm.org/D7036 llvm-svn: 226931

* Use -Wl,defs when linking.Rafael Espindola2015-01-201-2/+11
| | | | | | | | | | | | | | | ELF linkers by default allow shared libraries to contain undefined references and it is up to the dynamic linker to look for them. On COFF and MachO, that is not the case. This creates a situation where a .so might build on an ELF system, but the build of the corresponding .dylib or .dll will fail. This patch changes the cmake build to use -Wl,-z,defs when linking and updates the dependencies so that -DBUILD_SHARED_LIBS=ON build still works. llvm-svn: 226611
* Replace size method call of containers to empty method where appropriateAlexander Kornienko2015-01-158-13/+13
| | | | | | | | | | | | | | | | This patch was generated by a clang tidy checker that is being open sourced. The documentation of that checker is the following: /// The emptiness of a container should be checked using the empty method /// instead of the size method. It is not guaranteed that size is a /// constant-time function, and it is generally more efficient and also shows /// clearer intent to use empty. Furthermore some containers may implement the /// empty method but not implement the size method. Using empty whenever /// possible makes it easier to switch to another container in the future.

* AsmParser/Bitcode: Add support for MDLocationDuncan P. N. Exon Smith2015-01-131-1/+6
| | | | | | | | | | | | This adds assembly and bitcode support for `MDLocation`. The assembly side is rather big, since this is the first `MDNode` subclass (that isn't `MDTuple`). Part of PR21433. (If you're wondering where the mountains of testcase updates are, we don't need them until I update `DILocation` and `DebugLoc` to actually use this class.) llvm-svn: 225830
* Add the llvm.frameallocate and llvm.recoverframeallocation intrinsicsReid Kleckner2015-01-131-1/+1
| | | | | | | | | | | | | | | | | | | | | These intrinsics allow multiple functions to share a single stack allocation from one function's call frame. The function with the allocation may only perform one allocation, and it must be in the entry block. Functions accessing the allocation call llvm.recoverframeallocation with the function whose frame they are accessing and a frame pointer from an active call frame of that function. These intrinsics are very difficult to inline correctly, so the intention is that they be introduced rarely, or at least very late during EH preparation.

* Target: Allow target specific operand typesTom Stellard2015-01-122-3/+6
| | | | | | | | | | | | | | | | | | | This adds two new fields to the RegisterOperand TableGen class: string OperandNamespace = "MCOI"; string OperandType = "OPERAND_REGISTER"; These fields can be used to specify a target specific operand type, which will be stored in the OperandType member of the MCOperandInfo object. This can be useful for targets that need to store some extra information about operands that cannot be expressed using the target independent types. For example, in the R600 backend, there are operands which can take either registers or immediates and it is convenient to be able to specify this in the TableGen definitions. llvm-svn: 225661
* Add a new utility script that helps update very simple regression tests.Chandler Carruth2015-01-121-0/+207
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This script is currently specific to x86 and limited to use with very small regression or feature tests using 'llc' and 'FileCheck' in a reasonably canonical way. It is in no way general purpose or robust at this point. However, it works quite well for simple examples. Here is the intended workflow: - Make a change that requires updating N test files and M functions' assertions within those files. - Stash the change. - Update those N test files' RUN-lines to look "canonical"[1]. - Refresh the FileCheck lines for either the entire file or select functions by running this script. - The script will parse the RUN lines and run the 'llc' binary you give it according to each line, collecting the asm. - It will then annotate each function with the appropriate FileCheck comments to check every instruction from the start of the first basic block to the last return. - There will be numerous cases where the script either fails to remove the old lines, or inserts checks which need to be manually editted, but the manual edits tend to be deletions or replacements of registers with FileCheck variables which are fast manual edits. - A common pattern is to have the script insert complete checking of every instruction, and then edit it down to only check the relevant ones. - Be careful to do all of these cleanups though! The script is designed to make transferring and formatting the asm output of llc into a test case fast, it is *not* designed to be authoratitive about what constitutes a good test! - Commit the nice fresh baseline of checks. - Unstash your change and rebuild llc. - Re-run script to regenerate the FileCheck annotations - Remember to re-cleanup these annotations!!! - Check the diff to make sure this is sane, checking the things you expected it to, and check that the newly updated tests actually pass. - Profit! Also, I'm *terrible* at writing Python, and frankly I didn't spend a lot of time making this script beautiful or well engineered. But it's useful to me and may be useful to others so I thought I'd send it out. http://reviews.llvm.org/D5546 llvm-svn: 225618
* IR: Add 'distinct' MDNodes to bitcode and assemblyDuncan P. N. Exon Smith2015-01-082-1/+3
| | | | | | | | | | | | | | | | | | Propagate whether `MDNode`s are 'distinct' through the other types of IR (assembly and bitcode). This adds the `distinct` keyword to assembly. Currently, no one actually calls `MDNode::getDistinct()`, so these nodes only get created for: - self-references, which are never uniqued, and - nodes whose operands are replaced that hit a uniquing collision. The concept of distinct nodes is still not quite first-class, since distinct-ness doesn't yet survive across `MapMetadata()`. Part of PR22111. llvm-svn: 225474

Eventually we should probably also support 'addr32' and 'addr16' in the assembler to override the address size on some of these instructions. But for now we'll just use special operand types that will lookup the current mode size to select the right instruction. llvm-svn: 225075

* On behalf of Matthew Wahab:Evgeny Astigeevich2014-12-161-1/+7
| | | | | | | | | | | | | | | | An instruction alias defined with InstAlias and an optional operand in the middle of the AsmString field, "..${a} <operands>", would get the final "}" printed in the instruction disassembly. This wouldn't happen if the optional operand appeared as the last item in the AsmString which is how the current backends avoided the problem. There don't appear to be any tests for this part of Tablegen but it passes the pre-commit tests. Manually tested the change by enabling the generic alias printer in the ARM backend and checking the output. Differential Revision: http://reviews.llvm.org/D6529 llvm-svn: 224348
* [MC] Reset the MCInst in the matcher function before adding opcode/operands.Ahmed Bougacha2014-12-161-0/+1
| | | | | | | | | | | | | | | | | | On X86, the Intel asm parser tries to match all memory operand sizes when none is explicitly specified. For LEA, which doesn't really have a memory operand (just a pointer one), this results in multiple successful matches, one for each memory size. There's no error because it's same opcode, so really, it's just one match. However, the tablegen'd matcher function adds opcode/operands to the passed MCInst, and this results in multiple duplicated operands. This commit clears the MCInst in the tablegen'd matcher function. We sometimes clear it when the match failed, so there's no expectation of keeping the previous content anyway. Differential Revision: http://reviews.llvm.org/D6670 llvm-svn: 224347
