* [MIPS] Avoid breakpoint in delay slotBhushan D. Attarde2015-08-261-0/+1
| | | | | | | | | | | | | | SUMMARY: This patch implements Target::GetBreakableLoadAddress() method that takes an address and checks for any reason there is a better address than this to put a breakpoint on. If there is then return that address. MIPS uses this method to avoid breakpoint in delay slot.

* [LLDB][MIPS] Detect MIPS application specific extensions like micromipsJaydeep Patil2015-07-161-1/+1
| | | | | | | | | | | | | | SUMMARY: The patch detects MIPS application specific extensions (ASE) like micromips by reading ELF header.e_flags and SHT_MIPS_ABIFLAGS section. MIPS triple does not contain ASE information like micromips, mips16, DSP, MSA etc. These can be read from header.e_flags or SHT_MIPS_ABIFLAGS section.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | <rdar://problem/13594769> Main changes in this patch include: - cleanup plug-in interface and use ConstStrings for plug-in names - Modfiied the BSD Archive plug-in to be able to pick out the correct .o file when .a files contain multiple .o files with the same name by using the timestamp - Modified SymbolFileDWARFDebugMap to properly verify the timestamp on .o files it loads to ensure we don't load updated .o files and cause problems when debugging The plug-in interface changes: Modified the lldb_private::PluginInterface class that all plug-ins inherit from: Changed: virtual const char * GetPluginName() = 0; To: virtual ConstString GetPluginName() = 0; Removed: virtual const char * GetShortPluginName() = 0; - Fixed up all plug-in to adhere to the new interface and to return lldb_private::ConstString values for the plug-in names. - Fixed all plug-ins to return simple names with no prefixes. Some plug-ins had prefixes and most ones didn't, so now they all don't have prefixed names, just simple names like "linux", "gdb-remote", etc. llvm-svn: 181631
* After discussing with Chris Lattner, we require C++11, so lets get rid of ↵Greg Clayton2013-04-181-9/+9

* Since we use C++11, we should switch over to using std::unique_ptr when ↵Greg Clayton2013-04-181-11/+11
| | | | | | | | C++11 is being used. To do this, we follow what we have done for shared pointers and we define a STD_UNIQUE_PTR macro that can be used and it will "do the right thing". Due to some API differences in std::unique_ptr and due to the fact that we need to be able to compile without C++11, we can't use move semantics so some code needed to change so that it can compile with either C++. Anyone wanting to use a unique_ptr or auto_ptr should now use the "STD_UNIQUE_PTR(TYPE)" macro. llvm-svn: 179779
* <rdar://problem/11730263>Greg Clayton2013-03-281-3/+5
| | | | | | | | | | PC relative loads are missing disassembly comments when disassembled in a live process. This issue was because some sections, like __TEXT and __DATA in libobjc.A.dylib, were being moved when they were put into the dyld shared cache. This could also affect any other system that slides sections individually. The solution is to keep track of wether the bytes we will disassemble are from an executable file (file address), or from a live process (load address). We now do the right thing based off of this input in all cases. llvm-svn: 178315

* <rdar://problem/13069948>Greg Clayton2013-01-251-2/+2
| | | | | | | | | | | | Major fixed to allow reading files that are over 4GB. The main problems were that the DataExtractor was using 32 bit offsets as a data cursor, and since we mmap all of our object files we could run into cases where if we had a very large core file that was over 4GB, we were running into the 4GB boundary. So I defined a new "lldb::offset_t" which should be used for all file offsets. After making this change, I enabled warnings for data loss and for enexpected implicit conversions temporarily and found a ton of things that I fixed. Any functions that take an index internally, should use "size_t" for any indexes and also should return "size_t" for any sizes of collections. llvm-svn: 173463

| | | | | | | | | | | | Fixed the DisassemblerLLVMC disassembler to parse more efficiently instead of parsing opcodes over and over. The InstructionLLVMC class now only reads the opcode in the InstructionLLVMC::Decode function. This can be done very efficiently for ARM and architectures that have fixed opcode sizes. For x64 it still calls the disassembler to get the byte size. Moved the lldb_private::Instruction::Dump(...) function up into the lldb_private::Instruction class and it now uses the function that gets the mnemonic, operandes and comments so that all disassembly is using the same code. Added StreamString::FillLastLineToColumn() to allow filling a line up to a column with a character (which is used by the lldb_private::Instruction::Dump(...) function). Modified the Opcode::GetData() fucntion to "do the right thing" for thumb instructions. llvm-svn: 156532
* Added a new disassembler plugin, DisassemblerLLVMC,Sean Callanan2012-02-171-0/+126
which uses the Disassembler.h interface to the LLVM disassemblers rather than the EnhancedDisassembly.h interface. Disassembler.h is a better-maintained API and will be stabler in the long term. Currently the output from Disassembler.h does not provide for symbolic disassembly in all the places that the old disassembler did, so I have gated (and disabled) the disassembler. It'll be easy to flip the switch later. In the meantime, to enable the new disassembler, uncomment "#define USE_NEW_DISASSEMBLER" in lldb.cpp. llvm-svn: 150772
