/* This is a rudimentary backtrace generator for boinc project applications.
|
|
*
|
|
* It is adapted from Apple Developer Technical Support Sample Code
|
|
* MoreisBetter / MoreDebugging / MoreBacktraceTest
|
|
* The symbols it displays are not always clean.
|
|
*
|
|
* This code handles Mac OS X 10.3.x through 10.4.2. It may require some
|
|
* adjustment for future OS versions; see the discussion of _sigtramp and
|
|
* PowerPC Signal Stack Frames below.
|
|
*
|
|
* For useful tips on using backtrace information, see Apple Tech Note 2123:
|
|
* http://developer.apple.com/technotes/tn2004/tn2123.html#SECNOSYMBOLS
|
|
*
|
|
* To convert addresses to correct symbols, use the atos command-line tool:
|
|
* atos -o path/to/executable/with/symbols address
|
|
* Note: if address 1a23 is hex, use 0x1a23.
|
|
*
|
|
* To demangle mangled C++ symbols, use the c++filt command-line tool.
|
|
* You may need to prefix C++ symbols with an additonal underscore before
|
|
* passing them to c++filt (so they begin with two underscore characters).
|
|
*
|
|
* Flags in backtrace:
|
|
* F this frame pointer is bad
|
|
* P this PC is bad
|
|
* S this frame is a signal handler
