* Move -dwarf-version to an MC level command line option so it'sEric Christopher2014-06-19

* llvm-mc: Add option for prefering hex format disassembly.Jim Grosbach2014-06-11
| | | | | | | | | Previously there was a separate mode entirely (--hdis vs. --disassemble).

* llvm-mc: error when -compress-debug-sections is requested and zlib is not linkedDavid Blaikie2014-03-28
| | | | | | | | | | This is a bit of a stab in the dark, since I have zlib on my machine. Just going to bounce it off the bots & see if it sticks. Do we have some convention for negative REQUIRES: checks? Or do I just need to add a feature like I've done here? git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@205050 91177308-0d34-0410-b5e6-96231b3b80d8
* DebugInfo: Support for compressed debug info sectionsDavid Blaikie2014-03-27
| | | | | | | | | | | | | | | | | | | 1) When creating a .debug_* section and instead create a .zdebug_ section. 2) When creating a fragment in a .zdebug_* section, make it a compressed fragment. 3) When computing the size of a compressed section, compress the data and use the size of the compressed data. 4) Emit the compressed bytes. Also, check that only if a section has a compressed fragment, then that is the only fragment in the section. Assert-fail if the fragment's data is modified after it is compressed.

* Replace OwningPtr<T> with std::unique_ptr<T>.Ahmed Charles2014-03-06
| | | | | | | | | | This compiles with no changes to clang/lld/lldb with MSVC and includes overloads to various functions which are used by those projects and llvm which have OwningPtr's as parameters. This should allow out of tree projects some time to move. There are also no changes to libs/Target, which should help out of tree targets have time to move, if necessary. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@203083 91177308-0d34-0410-b5e6-96231b3b80d8

* Replace the F_Binary flag with a F_Text one.Rafael Espindola2014-02-24
| | | | | | | | | After this I will set the default back to F_None. The advantage is that before this patch forgetting to set F_Binary would corrupt a file on windows. Forgetting to set F_Text produces one that cannot be read in notepad, which is a better failure mode :-) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@202052 91177308-0d34-0410-b5e6-96231b3b80d8

* Add an instruction deprecation feature to TableGen.Joey Gouly2013-09-12
| | | | | | | | | | | | | | | | | | | | | | | | The 'Deprecated' class allows you to specify a SubtargetFeature that the instruction is deprecated on. The 'ComplexDeprecationPredicate' class allows you to define a custom predicate that is called to check for deprecation. For example: ComplexDeprecationPredicate<"MCR"> would mean you would have to define the following function: bool getMCRDeprecationInfo(MCInst &MI, MCSubtargetInfo &STI, std::string &Info) Which returns 'false' for not deprecated, and 'true' for deprecated and store the warning message in 'Info'. The MCTargetAsmParser constructor was chaned to take an extra argument of the MCInstrInfo class, so out-of-tree targets will need to be changed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@190598 91177308-0d34-0410-b5e6-96231b3b80d8
* Generate compact unwind encoding from CFI directives.Bill Wendling2013-09-09
| | | | | | | | | | | | | | | | 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> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@190290 91177308-0d34-0410-b5e6-96231b3b80d8
* Add a wrapper for open.Rafael Espindola2013-07-16
| | | | | | | This centralizes the handling of O_BINARY and opens the way for hiding more differences (like how open behaves with directories). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186447 91177308-0d34-0410-b5e6-96231b3b80d8
* Use pointers to the MCAsmInfo and MCRegInfo.Bill Wendling2013-06-18
| | | | | | | | | | Someone may want to do something crazy, like replace these objects if they change or something. No functionality change intended. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184175 91177308-0d34-0410-b5e6-96231b3b80d8
* Remove the MachineMove class.Rafael Espindola2013-05-13
| | | | | | | | | | | | It was just a less powerful and more confusing version of MCCFIInstruction. A side effect is that, since MCCFIInstruction uses dwarf register numbers, calls to getDwarfRegNum are pushed out, which should allow further simplifications. I left the MachineModuleInfo::addFrameMove interface unchanged since this patch was already fairly big. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181680 91177308-0d34-0410-b5e6-96231b3b80d8

* We want the dwarf AT_producer for assembly source files to match clang'sKevin Enderby2013-01-16
| | | | | | | | | | | | | | | | AT_producer. Which includes clang's version information so we can tell which version of the compiler was used. This is the first of two steps to allow us to do that. This is the llvm-mc change to provide a method to set the AT_producer string. The second step, coming soon to a clang near you, will have the clang driver pass the value of getClangFullVersion() via an flag when invoking the integrated assembler on assembly source files. rdar://12955296 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@172630 91177308-0d34-0410-b5e6-96231b3b80d8

* Added a option to the disassembler to print immediates as hex.Kevin Enderby2012-12-05
| | | | | | | | | | | | | | | | | | | | | | This is for the lldb team so most of but not all of the values are to be printed as hex with this option. Some small values like the scale in an X86 address were requested to printed in decimal without the leading 0x. There may be some tweaks need to places that may still be in decimal that they want in hex. Specially for arm. I made my best guess. Any tweaks from here should be simple. I also did the best I know now with help from the C++ gurus creating the cleanest formatImm() utility function and containing the changes. But if someone has a better idea to make something cleaner I'm all ears and game for changing the implementation. rdar://8109283 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169393 91177308-0d34-0410-b5e6-96231b3b80d8
