...rsp updates. The two places I can think with some documentation are http://www.dwarfstd.org/doc/DWARF4.pdf (the 6.4 Call Frame Information section). This is the old .debug_frame, but that is where the idea came from. http://refspecs.linuxfoundation.org/LSB_4.1.0/LSB-Core-generic/LSB-Core-generic/ehframechpt.html http://refspecs.linuxfoundation.org/LSB_4.1.0/LSB-Core-generic/LSB-Core-generic/dwarfext.html#AEN1154 Cheers, Rafael

Hi Rafael, I've been staring at the CFI directives and have a question. Some background: I want to generate the compact unwind information using just the CFI directives. I *think* that this should be doable. The issue I'm facing right now is that I need to know how much the stack pointer was adjusted. So when I have something like this: .cfi_startproc Lfunc_begin175:

Nick, Do you happen to know why the version reported in 'dwarfdump --eh-frame' for object files now differs when compiled with and without -g? The test used in FSF gcc's configure produces a diff of.. % diff -u conftest.o.g.stripped.dwarfdump conftest.o.g0.stripped.dwarfdump --- conftest.o.g.stripped.dwarfdump 2015-04-10 21:43:15.000000000 -0400 +++
