perf tools: Add libdw DWARF post unwind support for ARM

2014-05-16T09:39:29+00:00

Adding libdw DWARF post unwind support, which is part
of elfutils-devel/libdw-dev package from version 0.158.

The new code is contained in unwin-libdw.c object, and
implements unwind__get_entries unwind interface function.

perf tests: Add dwarf unwind test on ARM

2014-05-16T09:39:18+00:00

Adding dwarf unwind test, that setups live machine data over
the perf test thread and does the remote unwind.

Need to use -fno-optimize-sibling-calls for test compilation,
otherwise 'krava_*' function calls are optimized into jumps
and omitted from the stack unwind.

So far it was enabled only for x86.

perf tests: Introduce perf_regs_load function on ARM

2014-05-16T09:39:05+00:00

Introducing perf_regs_load function, which is going
to be used for dwarf unwind test in following patches.

It takes single argument as a pointer to the regs dump
buffer and populates it with current registers values.

Renaming unwind__arch_reg_id into libunwind__arch_reg_id, so it's clear
it's specific to libunwind.

perf callchain: Separate libunwind code to special object

2014-02-18T12:34:48+00:00

We are going to add libdw library support to do dwarf post unwind.

Making the code ready by moving libunwind dwarf post unwind stuff into
separate object.

perf tools: Fix build on non-glibc systems due to libio.h absence

2013-03-15T16:05:13+00:00

Including libio.h causes build failures on uClibc systems (which lack
libio.h).

It appears that libio.h was only included to pull in a definition for
NULL, so it has been replaced by stddef.h.

On powerpc, libio.h was conditionally included, but could be removed
completely as it is unneeded. Also, the included of stdlib.h was changed
to stddef.h (as again, only NULL is needed).

ARM: fix perf build with uclibc toolchains

2011-08-12T14:40:20+00:00

libio.h is not provided by uClibc, in order to be able to test the
definition of __UCLIBC__ we need to include stdlib.h, which also
includes stddef.h, providing the definition of 'NULL'.
