| | | | | | | | | | | | 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

| | | | | | | | | | | | | The output of 'register read' should be prettier. Modify RegisterValue::Dump() to take an additional parameter: uint32_t reg_name_right_align_at which defaults to 0 (i.e., no alignment at all). Update the 'register read' command impl to pass 8 as the alignment to RegisterValue::Dump() method. If more sophisticated scheme is desired, we will need to introduce an additional command option to 'register read' later on. llvm-svn: 158039

| | | | | | | | | | | | | | | | | | | | | | | Add logic to GDBRemoteRegisterContext class to be able to read/write a "composite" register which has "primordial" registers as its constituents. In particular, Read/WriteRegisterBytes() now delegate to Get/SetPrimordialRegister() helper methods to read/write register contents. Also modify RegisterValue class to be able to parse "register write" string value for the NEON quadword registers which is displayed as a vector of uint8's. Example: (lldb) register write q0 "{0x01 0x02 0x03 0x04 0x05 0x06 0x07 0x08 0x09 0x0a 0x0b 0x0c 0x0d 0x0e 0x0f 0x10}" (lldb) register read q0 q0 = {0x01 0x02 0x03 0x04 0x05 0x06 0x07 0x08 0x09 0x0a 0x0b 0x0c 0x0d 0x0e 0x0f 0x10} (lldb) register read --format uint8_t[] s0 s0 = {0x01 0x02 0x03 0x04} (lldb) register read --format uint8_t[] d0 d0 = {0x01 0x02 0x03 0x04 0x05 0x06 0x07 0x08} (lldb) register read --format uint8_t[] d1 d1 = {0x09 0x0a 0x0b 0x0c 0x0d 0x0e 0x0f 0x10} llvm-svn: 151939

* Fixed some issues with ARM backtraces by not processing any push/pop Greg Clayton2011-07-061-0/+147
| | | | | | | | | | | | | | instructions if they are conditional. Also fixed issues where the PC wasn't getting bit zero stripped for ARM targets when a stack frame was thumb. We now properly call through the GetOpcodeLoadAddress() functions to make sure the addresses are properly stripped for any targets that may decorate up their addresses. We now don't pass the SIGSTOP signals along. We can revisit this soon, but currently this was interfering with debugging some older ARM targets that don't have vCont support in the GDB server. llvm-svn: 134461
* Added a way to resolve an load address from a target:Greg Clayton2011-05-181-1/+71
| | | | | | | | | | | | | | | | | | | | bool Address::SetLoadAddress (lldb::addr_t load_addr, Target *target); Added an == and != operator to RegisterValue. Modified the ThreadPlanTracer to use RegisterValue objects to store the register values when single stepping. Also modified the output to be a bit less wide. Fixed the ABIMacOSX_arm to not overwrite stuff on the stack. Also made the trivial function call be able to set the ARM/Thumbness of the target correctly, and also sets the return value ARM/Thumbness. Fixed the encoding on the arm s0-s31 and d16 - d31 registers when the default register set from a standard GDB server register sets. llvm-svn: 131517
* Added generic register numbers for simple ABI argument registers and definedGreg Clayton2011-05-151-3/+39
| | | | | | | | | | | | | | | | | the appropriate registers for arm and x86_64. The register names for the arguments that are the size of a pointer or less are all named "arg1", "arg2", etc. This allows you to read these registers by name: (lldb) register read arg1 arg2 arg3 ... You can also now specify you want to see alternate register names when executing the read register command: (lldb) register read --alternate (lldb) register read -A llvm-svn: 131376
* While implementing unwind information using UnwindAssemblyInstEmulation I ranGreg Clayton2011-05-091-0/+896
into some cleanup I have been wanting to do when reading/writing registers. Previously all RegisterContext subclasses would need to implement: virtual bool ReadRegisterBytes (uint32_t reg, DataExtractor &data); virtual bool WriteRegisterBytes (uint32_t reg, DataExtractor &data, uint32_t data_offset = 0); There is now a new class specifically designed to hold register values: lldb_private::RegisterValue The new register context calls that subclasses must implement are: virtual bool ReadRegister (const RegisterInfo *reg_info, RegisterValue &reg_value) = 0; virtual bool WriteRegister (const RegisterInfo *reg_info, const RegisterValue &reg_value) = 0; The RegisterValue class must be big enough to handle any register value. The class contains an enumeration for the value type, and then a union for the data value. Any integer/float values are stored directly in an appropriate host integer/float. Anything bigger is stored in a byte buffer that has a length and byte order. The RegisterValue class also knows how to copy register value bytes into in a buffer with a specified byte order which can be used to write the register value down into memory, and this does the right thing when not all bytes from the register values are needed (getting a uint8 from a uint32 register value..). All RegiterContext and other sources have been switched over to using the new regiter value class. llvm-svn: 131096
