This patch includes the following changes: # Add CMIUtilString::ConvertToASCII to convert unicode to ASCII (MI) # Rework CMICmnLLDBUtilSBValue::GetSimpleValue to print wide/unicode char (MI) ## Add CMICmnLLDBUtilSBValue::GetSimpleValueChar ## Extend CMICmnLLDBUtilSBValue::IsCharType to accept char16_t/char32_t ## Don't ignore the fail_value in SBValue::GetValueAsUnsigned # Rework CMIUtilString::ConvertToASCII (MI) ## Don't use templates ## Change the function signature to convert signle characters (was std::basic_string) ## Rename CMIUtilString::ConvertToASCII to CMIUtilString::ConvertToPrintableASCII # Add CMIUtilString::ConvertToPrintableASCII for char (MI) ## Refactor CMIUtilString::Escape ## Simplify CMICmnLLDBUtilSBValue::GetSimpleValueChar for char # Add char16_t* and char32_t* support in CMICmnLLDBUtilSBValue::GetSimpleValue (MI) ## Add CMICmnLLDBUtilSBValue::GetSimpleValueCStringPointer ## Add CMICmnLLDBUtilSBValue::ReadCStringFromHostMemory2 (it's extended version of CMICmnLLDBUtilSBValue::ReadCStringFromHostMemory) # Improve error checking in CMICmnLLDBUtilSBValue::GetSimpleValueChar (MI) # Refactor CMICmnLLDBUtilSBValue (MI) ## Remove CMICmnLLDBUtilSBValue::ReadCStringFromHostMemory (use CMICmnLLDBUtilSBValue::ReadCStringFromHostMemory2 instead) ## Rename CMICmnLLDBUtilSBValue::ReadCStringFromHostMemory2 to CMICmnLLDBUtilSBValue::ReadCStringFromHostMemory ## Move CMICmnLLDBUtilSBValue::GetValueCString to private methods ## Rename CMICmnLLDBUtilSBValue::GetValueCString to CMICmnLLDBUtilSBValue::GetSimpleValueCStringArray ## Remove CMICmnLLDBUtilSBValue::GetChildValueCString # Improve MiGdbSetShowTestCase.test_lldbmi_gdb_set_show_print_char_array_as_string test to check char16_t/char32_t (MI) # Fix CMICmnLLDBUtilSBValue::GetSimpleValueCStringArray for Unicode (MI) ## Fix handling of char16_t and char32_t ## Improve CMICmnLLDBUtilSBValue::ReadCStringFromHostMemory to read variables of type char[]: add vnMaxLen argument ## Turn on few cases to check char16_t[] and char32_t[] output in MiGdbSetShowTestCase.test_lldbmi_gdb_set_show_print_char_array_as_string # Remove unnecessary checks in CMICmnLLDBUtilSBValue (MI) llvm-svn: 236827
