[LLVMdev] Generating a backtrace
...deal with are the libc
startup function, and _Unwind_Raise_Exception itself. Yet I know these
functions have symbolic names, since I can step through them in gdb, set
breakpoints, and so on.
I've tried a number of other approaches: Calling dlopen(NULL) and then using
dlsym() to try and locate __data_start so that I can then attempt to
manually parse the DWARF debug frames to translate the return addresses into
function names. Unfortunately, I can't seem to locate __data_start at all.
I've also tried calling the libc backtrace() function, but it produced
similarly useless results.
The really...

[PATCH 0/2] Fixes for gcc 5
From: Sylvain Gault <sylvain.gault at gmail.com>
TL;DR: The section aligment in linker scripts messed-up the memory mapping
needed for the compression / decompression to work.
The bug with gcc 5 is not trivial, I'll do my best to explain it here.
Basically, there are two memory mappings of the code. One in "virtual memory",
and one in "load memory". The one in

[PATCH 0/4] Improve linker scripts
From: Sylvain Gault <sylvain.gault at gmail.com>
These patches basically remove unused linker scripts and port a change that was
made to an unused script.
Those are to be applied on top of the gcc 5 bug fixes as they would conflict
otherwise.
Sylvain Gault (4):
diag/mbr: fix dependency to linker script
Remove unused linker scripts
core: Make symbols defined in linker script HIDDEN
