[gdb/testsuite] Fix .debug_aranges in dw2-case-insensitive-debug.S
When running gdb.dwarf2/dw2-case-insensitive.exp with target board
cc-with-debug-names, we run into:
...
FAIL: gdb.dwarf2/dw2-case-insensitive.exp: regexp case-sensitive off \
(GDB internal error)
...
in more detail:
...
(gdb) info functions fUnC_lang
gdb/dwarf2read.c:5293: internal-error: \
compunit_symtab* dw2_find_pc_sect_compunit_symtab(objfile*, \
bound_minimal_symbol, CORE_ADDR, obj_section*, int): \
Assertion `result != NULL' failed.
...
The problem is that the .debug_aranges section in dw2-case-insensitive-debug.S
contains a debug_info_offset which is set to 0:
...
.section .debug_aranges,"",@progbits
.4byte .Laranges_end - .Laranges_start
.Laranges_start:
.2byte 0x2
.4byte 0
...
while the compilation unit at offset 0 in the .debug_section of the executable
is in fact not the compilation unit generated from
dw2-case-insensitive-debug.S.
This happens when linked in object files contain dwarf info and are placed in
the .debug_info section before the compilation unit generated from
dw2-case-insensitive-debug.S.
Fix this by defining the debug_info_offset field using the label .Lcu1_begin
that defines the start of the compilation unit:
...
- .4byte 0
+ .4byte .Lcu1_begin
...
Tested on x86_64-linux with native, cc-with-gdb-index and cc-with-debug-names.
