vendor/google/tools/stack exists, but isn't part of the published sources. It has some google-internal build server stuff to make it easier for us to grab the symbol files from specific releases. We can't release it unless somebody runs through and deletes all the google-specific goodies, which must be done without breaking anything; so far that hasn't happened. The key bit is this (python): # Copyright (C) 2008 The Android Open Source Project # License at http://www.apache.org/licenses/LICENSE-2.0 # returns a list containing the function name and the file/lineno def CallAddr2Line(lib, addr): uname = os.uname()[0] if uname == "Darwin": proc = os.uname()[-1] if proc == "i386": uname = "darwin-x86" else: uname = "darwin-ppc" elif uname == "Linux": uname = "linux-x86" if lib != "": cmd = "./prebuilt/" + uname + \ "/toolchain/arm-eabi-4.2.1/bin/arm-eabi-addr2line" \ + " -f -e " + SYMBOLS_DIR + lib \ + " 0x" + addr stream = os.popen(cmd) lines = stream.readlines() list = map(string.strip, lines) else: list = [] if list != []: # Name like "move_forward_type<JavaVMOption>" causes troubles mangled_name = re.sub('<', '\<', list[0]); mangled_name = re.sub('>', '\>', mangled_name); cmd = "./prebuilt/" + uname + "/toolchain/arm-eabi-4.2.1/bin/arm- eabi-c++filt "\ + mangled_name stream = os.popen(cmd) list[0] = stream.readline() stream.close() list = map(string.strip, list) else: list = [ "(unknown)", "(unknown)" ] return list where uname is usually "linux-x86". Wrap the above in a loop and just paste in the necessary bits, or make a smarter script that automatically finds the start of the stack trace. There was a change-up somewhere along the way between relative and absolute addresses that can be worked around by zeroing out the high 12 bits. The stuff posted earlier in this thread appeared to be relative, so you may not have to worry about it. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Developers" group.
