* Replace a few more "fall through" comments with LLVM_FALLTHROUGHJustin Bogner2016-08-171-1/+1

* Pass an ArrayRef to MCDisassembler::getInstruction.Rafael Espindola2014-11-121-3/+2
| | | | | | | | | | | | With this patch MCDisassembler::getInstruction takes an ArrayRef<uint8_t> instead of a MemoryObject. Even on X86 there is a maximum size an instruction can have. Given that, it seems way simpler and more efficient to just pass an ArrayRef to the disassembler instead of a MemoryObject and have it do a virtual call every time it wants some extra bytes. llvm-svn: 221751

* [MC] Require an MCContext when constructing an MCDisassembler.Lang Hames2014-04-151-1/+21
| | | | | | | | | | | | | | | | This patch re-introduces the MCContext member that was removed from MCDisassembler in r206063, and requires that an MCContext be passed in at MCDisassembler construction time. (Previously the MCContext member had been initialized in an ad-hoc fashion after construction). The MCCContext member can be used by MCDisassembler sub-classes to construct constant or target-specific MCExprs. This patch updates disassemblers for in-tree targets, and provides the MCRegisterInfo instance that some disassemblers were using through the MCContext (previously those backends were constructing their own MCRegisterInfo instances). llvm-svn: 206241

* Replace OwningPtr<T> with std::unique_ptr<T>.Ahmed Charles2014-03-061-2/+1
| | | | | | | | | | 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. llvm-svn: 203083
* Change MCStreamer EmitInstruction interface to take subtarget infoDavid Woodhouse2014-01-281-3/+4
| | | | llvm-svn: 200345
* Improve llvm-mc disassembler mode and refactor ARM tests to use itTim Northover2013-07-191-12/+60
| | | | | | | | | | | | | | | | | | This allows "llvm-mc -disassemble" to accept two new features: + Using comma as a byte separator + Grouping bytes with '[' and ']' pairs. The behaviour outside a [...] group is unchanged. But within the group once llvm-mc encounters a true error, it stops rather than trying to resynchronise the stream at the next byte. This is more useful for disassembly tests, where we have an almost-instruction in mind and don't care what the misaligned interpretation would be. Particularly if it means llvm-mc won't actually see the next intended almost-instruction. As a side effect, this means llvm-mc can disassemble its own -show-encoding output if copy-pasted. llvm-svn: 186661
* Remove edis - the enhanced disassembler. Fixes PR14654.Roman Divacky2012-12-191-176/+0
| | | | llvm-svn: 170578
* Sort the #include lines for tools/...Chandler Carruth2012-12-041-2/+2
| | | | | | | | Again, tools are trickier to pick the main module header for than library source files. I've started to follow the pattern of using LLVMContext.h when it is included as a stub for program source files. llvm-svn: 169252
* Add -disassemble support for -show-inst and -show-encode capability llvm-mc. ↵Richard Barton2012-04-161-53/+14
| | | | | | | | Also refactor so all MC paraphernalia are created once for all uses as much as possible. The test change is to account for the fact that the default disassembler behaviour has changed with regards to specifying the assembly syntax to use. llvm-svn: 154809

* Enable streaming of bitcodeDerek Schuff2012-02-061-2/+2
| | | | | | | This CL delays reading of function bodies from initial parse until materialization, allowing overlap of compilation with bitcode download. llvm-svn: 149918

* start straightening out libedis's dependencies and make it fitChris Lattner2010-07-201-82/+57
| | | | | | | | | | | | | | | | better in the llvm world. Among other things, this changes: 1. The guts of libedis are now moved into lib/MC/MCDisassembler 2. llvm-mc now depends on lib/MC/MCDisassembler, not tools/edis, so edis and mc don't have to be built in series. 3. lib/MC/MCDisassembler no longer depends on the C api, the C API depends on it. 4. Various code cleanup changes. There is still a lot to be done to make edis fit with the llvm design, but this is an incremental step in the right direction. llvm-svn: 108869
