libc_arm: avoid multiple version of __aeabi_unwind_cpp_pr dummy code

2012-01-27T09:05:09+00:00

Do not pollute libraries with its own implementation of __aeabi_unwind_cpp_pr1 code.
Just add it to uclibc_nonshared.a archive and share it.
This fixes build issue with static linking of application due to multiple symbol
definition in libgcc_eh-a and libpthread.a or librt.a

libubacktrace: Add arm implementation

2012-01-24T00:10:39+00:00

Arm has a different mechanism of getting
_Unwind_GetIP. Therefore we provide arch
specific backtrace file.

libubacktrace: use -asynchronous-funwind-tables rather than -funwind-tables

2012-01-13T11:27:29+00:00

From gcc documentation, we can read:
" ...
-fasynchronous-unwind-tables
    Generate unwind table in dwarf2 format, if supported by target
    machine. The table is exact at each instruction boundary, so it can be
    used for stack unwinding from asynchronous events (such as debugger or
    garbage collector)
..."

So it seems better rather than using -funwind-tables (glibc seems to prefer
-fasynchronous-unwind-tables).

libubacktrace: use -funwind-tables rather than -fexecptions

2011-12-22T14:30:20+00:00

For backtrace to work is enough to use -funwind-tables instead
of -fexceptions.

Revert "libubacktrace: fix config-symbol handling"

2011-05-11T17:16:17+00:00

This reverts commit 7a080cd149c7b25d415d76506510d55b34819fc2.

This symbol is in fact different (as it is set no 'n').

libubacktrace: fix config-symbol handling

2011-05-11T07:56:55+00:00

Config symbals that are not set are empty, not 'n'.
