* Re-sort all of the includes with ./utils/sort_includes.py so thatChandler Carruth2014-01-073-3/+3
| | | | | | | | | | 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
* ARM MachO: sort out isTargetDarwin/isTargetIOS/... checks.Tim Northover2014-01-062-4/+4
| | | | | | | | | | | | | | | | | | The ARM backend has been using most of the MachO related subtarget checks almost interchangeably, and since the only target it's had to run on has been IOS (which is all three of MachO, Darwin and IOS) it's worked out OK so far. But we'd like to support embedded targets under the "*-*-none-macho" triple, which means everything starts falling apart and inconsistent behaviours emerge. This patch should pick a reasonably sensible set of behaviours for the new triple (and any others that come along, with luck). Some choices were debatable (notably FP == r7 or r11), but we can revisit those later when deficiencies become apparent. llvm-svn: 198617

* Add OpSize16 bit, for instructions which need 0x66 prefix in 16-bit modeCraig Topper2014-01-062-5/+6
| | | | | | | | | | | | | | | | | The 0x66 prefix toggles between 16-bit and 32-bit addressing mode. So in 32-bit mode it is used to switch to 16-bit addressing mode for the following instruction, while in 16-bit mode it's the other way round — it's used to switch to 32-bit mode instead. Thus, emit the 0x66 prefix byte for OpSize only in 32-bit (and 64-bit) mode, and introduce a new OpSize16 bit which is used in 16-bit mode instead. This is just the basic infrastructure for that change; a subsequent patch will add the new OpSize16 bit to the 32-bit instructions that need it. Patch from David Woodhouse. llvm-svn: 198586
* [x86] Add basic support for .code16Craig Topper2014-01-062-4/+12
| | | | | | | | | | | This is not really expected to work right yet. Mostly because we will still emit the OpSize (0x66) prefix in all the wrong places, along with a number of other corner cases. Those will all be fixed in the subsequent commits. Patch from David Woodhouse. llvm-svn: 198584
* Fix ModR/M byte output for 16-bit addressing modes (PR18220)Craig Topper2014-01-051-0/+60
| | | | | | | | | Add some tests to validate correct register selection, including a fix to an existing test which was requiring the *wrong* output. Patch from David Woodhouse. llvm-svn: 198566
* Make the llvm mangler depend only on DataLayout.Rafael Espindola2014-01-031-8/+2
| | | | | | | | | | | | | | Before this patch any program that wanted to know the final symbol name of a GlobalValue had to link with Target. This patch implements a compromise solution where the mangler uses DataLayout. This way, any tool that already links with Target (llc, clang) gets the exact behavior as before and new IR files can be mangled without linking with Target. With this patch the mangler is constructed with just a DataLayout and DataLayout is extended to include the information the Mangler needs. llvm-svn: 198438

* Make Triple's isOSBinFormatXXX functions partition triple-space.Tim Northover2013-12-101-1/+1
| | | | | | | | | | | Most users would be surprised if "isCOFF" and "isMachO" were simultaneously true, unless they'd put the compiler in a box with a gun attached to a photon detector. This makes sure precisely one of the three formats is true for any triple and simplifies some target logic based on that. llvm-svn: 196934

* Fix a bug in darwin's 32-bit X86 handling of evaluating fixups. Kevin Enderby2013-12-041-1/+4
| | | | | | | | | | | | | | | Where it would use a scattered relocation entry but falls back to a normal relocation entry because the FixupOffset is more than 24-bits. The bug is in the X86MachObjectWriter::RecordScatteredRelocation() where it changes reference parameter FixedValue but then returns false to indicate it did not create a scattered relocation entry. The fix is simply to save the original value of the parameter FixedValue at the start of the method and restore it if we are returning false in that case. rdar://15526046 llvm-svn: 196432

* Don't use nopl in cpus that don't support it.Rafael Espindola2013-11-251-1/+5
| | | | | | | | | | | | | | | Patch by Mikulas Patocka. I added the test. I checked that for cpu names that gas knows about, it also doesn't generate nopl. The modified cpus: i686 - there are i686-class CPUs that don't have nopl: Via c3, Transmeta Crusoe, Microsoft VirtualBox - see https://bbs.archlinux.org/viewtopic.php?pid=775414 k6, k6-2, k6-3, winchip-c6, winchip2 - these are 586-class CPUs via c3 c3-2 - see https://bugs.archlinux.org/task/19733 as a proof that Via c3 and c3-Nehemiah don't have nopl llvm-svn: 195679
* [weak vtables] Remove a bunch of weak vtablesJuergen Ributzka2013-11-191-1/+1
| | | | | | | | | | | | This patch removes most of the trivial cases of weak vtables by pinning them to a single object file. The memory leaks in this version have been fixed.

* Revert r194865 and r194874.Alexey Samsonov2013-11-181-1/+1
| | | | | | | | | | | | This change is incorrect. If you delete virtual destructor of both a base class and a subclass, then the following code: Base *foo = new Child(); delete foo; will not cause the destructor for members of Child class. As a result, I observe plently of memory leaks. Notable examples I investigated are: ObjectBuffer and ObjectBufferStream, AttributeImpl and StringSAttributeImpl. llvm-svn: 194997

* MC asm parser: allow ?'s in symbol names, and handle @'s in names in MS asmHans Wennborg2013-10-181-0/+2
| | | | | | | | | | | | | | | | | | | | This is another (final?) stab at making us able to parse our own asm output on Windows. Symbols on Windows often contain @'s and ?'s in their names. Our asm parser didn't like this. ?'s were not allowed, and @'s were intepreted as trying to reference PLT/GOT/etc. We can't just add quotes around the bad names, since e.g. for MinGW, we use gas to assemble, and it doesn't like quotes in some places (notably in .def directives). This commit makes us allow ?'s in symbol names, and @'s in symbol names for MS assembly. Differential Revision: http://llvm-reviews.chandlerc.com/D1978 llvm-svn: 193000

| | | | | | | | | | | | | This patch fixes an old FIXME by creating a MCTargetStreamer interface and moving the target specific functions for ARM, Mips and PPC to it. The ARM streamer is still declared in a common place because it is used from lib/CodeGen/ARMException.cpp, but the Mips and PPC are completely hidden in the corresponding Target directories. I will send an email to llvmdev with instructions on how to use this. llvm-svn: 192181

* Generate compact unwind encoding from CFI directives.Bill Wendling2013-09-092-12/+359
| | | | | | | | | | | | | | | We used to generate the compact unwind encoding from the machine instructions. However, this had the problem that if the user used `-save-temps' or compiled their hand-written `.s' file (with CFI directives), we wouldn't generate the compact unwind encoding. Move the algorithm that generates the compact unwind encoding into the MCAsmBackend. This way we can generate the encoding whether the code is from a `.ll' or `.s' file. <rdar://problem/13623355> llvm-svn: 190290
* Fixed a crash in the integrated assembler for Mach-O when a symbol differenceKevin Enderby2013-09-051-0/+4

In the case of an assembler temporary symbol we want to use the AliasedSymbol (if any) which will create a local relocation entry, but if it is not an assembler temporary symbol then let it use that symbol with an external relocation entry. rdar://9356266 llvm-svn: 190096
