Summary: TestExprsChar.py Char is unsigned char by default in PowerPC. TestDisassembleBreakpoint.py Modify disassemble testcase to consider multiple architectures. TestThreadJump.py Jumping directly to the return line on PowerPC architecture dos not means returning the value that is seen on the code. The last test fails, because it needs the execution of some assembly in the beginning of the function. Avoiding this test for this architecture. TestEhFrameUnwind.py Implement func for ppc64le test case. TestWatchLocation.py TestStepOverWatchpoint.py PowerPC currently supports only one H/W watchpoint. TestDisassembleRawData.py Add PowerPC opcode and instruction for disassemble testcase.
