On arm-none-eabi target thumb mode, I see the following fail,
p the_int^M
$2 = 99^M
(gdb) FAIL: gdb.dwarf2/dwz.exp: p the_int
and on powerpc64 target, we even can't get function main from object
file,
disassemble main^M
No function contains specified address.^M
(gdb) FAIL: gdb.dwarf2/dwz.exp: disassemble main
This patch is to use MACRO_AT_func attribute to get the main's start
address and end address correctly, and also remove some code dwz.exp
getting main's length. This patch fixes fails on both thumb mode and
powerpc64 target.

* gdb.dwarf2/dwz.exp: Remove the code to compile main.c to
object and get function length.
(Dwarf::assemble): Replace name, low_pc and high_pc attributes
with MACRO_AT_func.
(top-level): Replace gdb_compile and clean_restart with
prepare_for_testing.
* gdb.dwarf2/main.c (main): Add label main_label.
In Dwarf::assemble in dwz.exp, 10 is hard-coded in it,
subprogram {
{name main}
{low_pc main addr}
{high_pc "main + 10" addr}
}
however, the length of main function varies on architectures. The
hard-coded 10 here causes dwz.exp fails on some targets, such as
nios2.
This patch is to add some code to compute the length of function main,
which is similar to what we are doing in entry-values.exp.
gdb/testsuite:
2014-04-26 Yao Qi <yao@codesourcery.com>
* gdb.dwarf2/dwz.exp: Compile main.c to object. Restart GDB
and compute the length of function main. Save it in
$main_length.
(Dwarf::assemble): Use $main_length instead of hard-coded 10.
(top-level): Use gdb_compile to compile objects into
executable and restart GDB. Remove invocation to
prepare_for_testing.
I happen to see that 'double_label' isn't used in dwz.exp dwarf assembler.
Similarly, partial_label and double_label aren't used in dwzbuildid.exp.
This patch is to remove them.
gdb/testsuite:
2014-04-25 Yao Qi <yao@codesourcery.com>
* gdb.dwarf2/dwz.exp (Dwarf::assemble): Remove unused
double_label.
* gdb.dwarf2/dwzbuildid.exp (Dwarf::assemble): Remove
partial_label and double_label.
Now that prepare_for_testing etc. can cope with absolute path names,
this can be exploited for test cases with generated source files.
This is just to simplify the code and shouldn't cause any functional
change.
Doug pointed out a while ago that in the final dwz -m patch, nothing
ever set symtab::user.
This patch fixes this oversight and adds a test case showing why it is
important.
Built and regtested (both ways) on x86-64 Fedora 18.
The new test unconditionally tests the partial unit machinery, which I
think is an added plus.
* dwarf2read.c (recursively_compute_inclusions): Add
"immediate_parent" argument. Set symtab's "user" field
if not set.
(compute_symtab_includes): Update.
* gdb.dwarf2/dwz.exp: New file.
