gcc-4.4.2 testsuite failures:
FAIL: gcc.dg/tree-prof/bb-reorg.c compilation,  -fprofile-use -D_PROFILE_USE
FAIL: gcc.dg/tree-prof/pr34999.c compilation,  -fprofile-use -D_PROFILE_USE

using binutils 2.20.51.20090927

Copying sources to a temporary directory and repeating commands used by
testsuite produces this log:

$ ${GCC_BUILD}/gcc/xgcc bb-reorg.c -B${GCC_BUILD}/gcc/ -O2
-freorder-blocks-and-partition -fprofile-generate -D_PROFILE_GENERATE -lm -o

Omitting '-O2' fixes :

The same problem occurs with

This was fixed on the trunk, I don't have the changelog entry handy though, but
it was done by Jakub IIRC.

        * dwarf2out.c (output_fde): When doing hot/cold partitioning, use
        fde->dw_fde_begin as begin label instead of hot/cold label.
        Use LLSDAC label instead of LLSDA for second section lsda.
        (dwarf2out_do_cfi_startproc): Add SECOND argument.  Use LLSDAC
        label instead of LLSDA if it is true.
        (dwarf2out_begin_prologue, dwarf2out_switch_text_section): Adjust
        callers.
        * except.c (add_call_site, dw2_size_of_call_site_table): Add
        SECTION argument.  Use it as index into crtl->eh.call_site_record
        array.
        (dw2_output_call_site_table): Likewise.  Add CS_FORMAT argument,
        use it to determine how to print table entries instead of using
        #ifdef HAVE_AS_LEB128.  For SECTION > 0 use hot resp. cold
        label instead of normal begin label as base.
        (sjlj_assign_call_site_values): Adjust add_call_site caller.
        (convert_to_eh_region_ranges): When doing hot/cold partitioning,
        ensure no EH range spans between sections and that landing pads
        are always in the corresponding section.
        (sjlj_size_of_call_site_table, sjlj_output_call_site_table): Adjust
        for crtl->eh.call_site_record being an array rather than scalar.
        (output_one_function_exception_table): New function, copied
        from output_function_exception_table.  Adjust
        dw2_size_of_call_site_table, dw2_output_call_site_table
        callers.  For SECOND section use *C suffixed labels.
        (output_function_exception_table): Call
        output_one_function_exception_table and, when doing hot/cold
        partitioning, also another time for the second section.
        * opts.c: Include except.h.
        (decode_options): Allow -freorder-blocks-and-partition with
        exceptions, unless SJLJ or TARGET_UNWIND_INFO.
        * Makefile.in (opts.o): Depend on $(EXCEPT_H).
        * function.h (struct rtl_eh): Change call_site_record from
        scalar into array of 2 elements.

Patch on mainline needs to be backported to 4.4.x branch.

Too big for backporting (and not a regression?).
