* IR: Give 'DI' prefix to debug info metadataDuncan P. N. Exon Smith2015-04-291-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Finish off PR23080 by renaming the debug info IR constructs from `MD*` to `DI*`. The last of the `DIDescriptor` classes were deleted in r235356, and the last of the related typedefs removed in r235413, so this has all baked for about a week. Note: If you have out-of-tree code (like a frontend), I recommend that you get everything compiling and tests passing with the *previous* commit before updating to this one. It'll be easier to keep track of what code is using the `DIDescriptor` hierarchy and what you've already updated, and I think you're extremely unlikely to insert bugs. YMMV of course. Back to *this* commit: I did this using the rename-md-di-nodes.sh upgrade script I've attached to PR23080 (both code and testcases) and filtered through clang-format-diff.py. I edited the tests for test/Assembler/invalid-generic-debug-node-*.ll by hand since the columns were off-by-three. It should work on your out-of-tree testcases (and code, if you've followed the advice in the previous paragraph). Some of the tests are in badly named files now (e.g., test/Assembler/invalid-mdcompositetype-missing-tag.ll should be 'dicompositetype'); I'll come back and move the files in a follow-up commit. llvm-svn: 236120
* [AsmPrinter] Make AsmPrinter's OutStreamer member a unique_ptr.Lang Hames2015-04-241-16/+16
| | | | | | | AsmPrinter owns the OutStreamer, so an owning pointer makes sense here. Using a reference for this is crufty. llvm-svn: 235752
* DebugInfo: Gut DIVariable and DIGlobalVariableDuncan P. N. Exon Smith2015-04-141-2/+2
| | | | | | | | | | Gut all the non-pointer API from the variable wrappers, except an implicit conversion from `DIGlobalVariable` to `DIDescriptor`. Note that if you're updating out-of-tree code, `DIVariable` wraps `MDLocalVariable` (`MDVariable` is a common base class shared with `MDGlobalVariable`). llvm-svn: 234840
* Refactor a lot of duplicated code for stub output.Rafael Espindola2015-04-071-23/+0
| | | | | | | This also moves it earlier so that it they are produced before we print an end symbol for the data section. llvm-svn: 234315

* Centralize the handling of unique ids for temporary labels.Rafael Espindola2015-03-171-3/+2
| | | | | | | | | | | | | | | | Before this patch code wanting to create temporary labels for a given entity (function, cu, exception range, etc) had to keep its own counter to have stable symbol names. createTempSymbol would still add a suffix to make sure a new symbol was always returned, but it kept a single counter. Because of that, if we were to use just createTempSymbol("cu_begin"), the label could change from cu_begin42 to cu_begin43 because some other code started using temporary labels. Simplify this by just keeping one counter per prefix and removing the various specialized counters. llvm-svn: 232535
* Convert the easy cases of GetTempSymbol to createTempSymbol.Rafael Espindola2015-03-171-1/+1

* Fix PR22408 - LLVM producing AArch64 TLS relocations that GNU linkers cannot ↵Kristof Beyls2015-03-041-12/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | handle yet. As is described at http://llvm.org/bugs/show_bug.cgi?id=22408, the GNU linkers ld.bfd and ld.gold currently only support a subset of the whole range of AArch64 ELF TLS relocations. Furthermore, they assume that some of the code sequences to access thread-local variables are produced in a very specific sequence. When the sequence is not as the linker expects, it can silently mis-relaxe/mis-optimize the instructions. Even if that wouldn't be the case, it's good to produce the exact sequence, as that ensures that linkers can perform optimizing relaxations. This patch: * implements support for 16MiB TLS area size instead of 4GiB TLS area size. Ideally clang would grow an -mtls-size option to allow support for both, but that's not part of this patch. * by default doesn't produce local dynamic access patterns, as even modern ld.bfd and ld.gold linkers do not support the associated relocations. An option (-aarch64-elf-ldtls-generation) is added to enable generation of local dynamic code sequence, but is off by default. * makes sure that the exact expected code sequence for local dynamic and general dynamic accesses is produced, by making use of a new pseudo instruction. The patch also removes two (AArch64ISD::TLSDESC_BLR, AArch64ISD::TLSDESC_CALL) pre-existing AArch64-specific pseudo SDNode instructions that are superseded by the new one (TLSDESC_CALLSEQ). llvm-svn: 231227

* Move DataLayout back to the TargetMachine from TargetSubtargetInfoEric Christopher2015-01-261-1/+1
| | | | | | | | | | | | | | | | | | | 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

* AArch64: remove "arm64_be" support in favour of "aarch64_be".Tim Northover2014-07-231-3/+1
| | | | | | | | | There really is no arm64_be: it was a useful fiction to test big-endian support while both backends existed in parallel, but now the only platform that uses the name (iOS) doesn't have a big-endian variant, let alone one called "arm64_be". llvm-svn: 213748

* AArch64: support 'c' and 'n' inline asm modifiers.Tim Northover2014-05-271-0/+5
| | | | | | | These are tested by test/CodeGen/Generic, so we should probably know how to deal with them. Fortunately generic code does it if asked. llvm-svn: 209646
* AArch64/ARM64: move ARM64 into AArch64's placeTim Northover2014-05-241-0/+519
| | | | | | | | | | | | | | | This commit starts with a "git mv ARM64 AArch64" and continues out from there, renaming the C++ classes, intrinsics, and other target-local objects for consistency. "ARM64" test directories are also moved, and tests that began their life in ARM64 use an arm64 triple, those from AArch64 use an aarch64 triple. Both should be equivalent though. This finishes the AArch64 merge, and everyone should feel free to continue committing as normal now. llvm-svn: 209577
* AArch64/ARM64: remove AArch64 from tree prior to renaming ARM64.Tim Northover2014-05-241-303/+0
| | | | | | | | | | | | | | | | I'm doing this in two phases for a better "git blame" record. This commit removes the previous AArch64 backend and redirects all functionality to ARM64. It also deduplicates test-lines and removes orphaned AArch64 tests. The next step will be "git mv ARM64 AArch64" and rewire most of the tests. Hopefully LLVM is still functional, though it would be even better if no-one ever had to care because the rename happens straight afterwards. llvm-svn: 209576

* Re-sort all of the includes with ./utils/sort_includes.py so thatChandler Carruth2014-01-071-1/+1
| | | | | | | | | | subsequent changes are easier to review. About to fix some layering issues, and wanted to separate out the necessary churn. Also comment and sink the include of "Windows.h" in three .inc files to match the usage in Memory.inc. llvm-svn: 198685
* Remove dead code.Rafael Espindola2013-12-021-4/+0
| | | | | | | | | MO_JumpTableIndex and MO_ExternalSymbol don't show up on inline asm. Keeping parts of the old asm printer just to print inline asm to a string that we then parse back looks like a hack. llvm-svn: 196111

* AArch64: use default asm operand printing when modifier inapplicableTim Northover2013-11-041-47/+59
| | | | | | | | | | | | If an inline assembly operand has multiple constraints (e.g. "Ir" for immediate or register) and an operand modifier (E.g. "w" for "print register as wN") then we need to decide behaviour when the modifier doesn't apply to the constraint. Previousely produced some combination of an assertion failure and a fatal error. GCC's behaviour appears to be to ignore the modifier and print the operand in the default way. This patch should implement that. llvm-svn: 194024
* Add a helper getSymbol to AsmPrinter.Rafael Espindola2013-10-291-1/+1

* AArch64: add 'a' inline asm operand modifierTim Northover2013-10-291-0/+2
| | | | | | | This is used in the Linux kernel, and effectively just means "print an address". llvm-svn: 193593
* AArch64: use RegisterOperand for NEON registers.Tim Northover2013-09-131-19/+7
| | | | | | | | | | | | | | | | Previously we modelled VPR128 and VPR64 as essentially identical register-classes containing V0-V31 (which had Q0-Q31 as "sub_alias" sub-registers). This model is starting to cause significant problems for code generation, particularly writing EXTRACT/INSERT_SUBREG patterns for converting between the two. The change here switches to classifying VPR64 & VPR128 as RegisterOperands, which are essentially aliases for RegisterClasses with different parsing and printing behaviour. This fits almost exactly with their real status (VPR128 == FPR128 printed strangely, VPR64 == FPR64 printed strangely). llvm-svn: 190665
* Remove address spaces from MC.Rafael Espindola2013-07-021-1/+1
| | | | | | | | This is dead code since PIC16 was removed in 2010. The result was an odd mix, where some parts would carefully pass it along and others would assert it was zero (most of the object streamer for example). llvm-svn: 185436
* DebugInfo: remove target-specific Frame Index handling for DBG_VALUE ↵David Blaikie2013-06-161-40/+0
| | | | | | | | | | MachineInstrs Frame index handling is now target-agnostic, so delete the target hooks for creation & asm printing of target-specific addressing in DBG_VALUEs and any related functions. llvm-svn: 184067
* AArch64: remove ConstantIsland pass & put literals in separate section.Tim Northover2013-02-151-16/+0
| | | | | | | | This implements the review suggestion to simplify the AArch64 backend. If we later discover that we *really* need the extra complexity of the ConstantIslands pass for performance reasons it can be resurrected. llvm-svn: 175258
* Fix formatting in AArch64 backend.Tim Northover2013-02-051-2/+4
| | | | | | | | | | | This should fix three purely whitespace issues: + 80 column violations. + Tab characters. + TableGen brace placement. No functional changes. llvm-svn: 174370
* Add AArch64 as an experimental target.Tim Northover2013-01-311-0/+361
This patch adds support for AArch64 (ARM's 64-bit architecture) to LLVM in the "experimental" category. Currently, it won't be built unless requested explicitly. This initial commit should have support for: + Assembly of all scalar (i.e. non-NEON, non-Crypto) instructions (except the late addition CRC instructions). + CodeGen features required for C++03 and C99. + Compilation for the "small" memory model: code+static data < 4GB. + Absolute and position-independent code. + GNU-style (i.e. "__thread") TLS. + Debugging information. The principal omission, currently, is performance tuning. This patch excludes the NEON support also reviewed due to an outbreak of batshit insanity in our legal department. That will be committed soon bringing the changes to precisely what has been approved. Further reviews would be gratefully received. llvm-svn: 174054
