When compiling dw2-multiple-debug-info.c using -gdwarf-5
-fdebug-types-section, we end with two .debug_info sections in the object
file:
...
$ g++ gdb.dwarf2/dw2-multiple-debug-info.c -c -g \
-gdwarf-5 \
-fdebug-types-section
$ readelf -WS dw2-multiple-debug-info.o | grep -v RELA | grep .debug_info
[10] .debug_info PROGBITS 0 000128 0000cd 00 GC 0 0 8
[12] .debug_info PROGBITS 0 0001f8 0000ad 00 C 0 0 8
...
One of them contains the CU for dw2-multiple-debug-info.c, the other contains
the TU for the type of variable a.
When trying to print the type of variable a, we get:
...
$ gdb -q -batch dw2-multiple-debug-info.o -ex "ptype a"
'a' has unknown type; cast it to its declared type
...
because the TU hasn't been read.
Fix this by adding support for reading multiple .debug_info sections, similar
to how that is done for multiple .debug_types sections, getting us instead:
...
$ gdb -q -batch dw2-multiple-debug-info.o -ex "ptype a"
type = class sp1::A {
...
}
...
Tested on x86_64-linux.
