Arnaldo Carvalho de Melo ac7778099a pahole: Introduce --fixup_silly_bitfields 
$ pahole -C acpi_device_perf_flags ac.o
struct acpi_device_perf_flags {
	u8          reserved:8;           /*     0: 0  1 */

	/* size: 1, cachelines: 1, members: 1 */
	/* last cacheline: 1 bytes */
};
$ pahole --fixup_silly_bitfields -C acpi_device_perf_flags ac.o
struct acpi_device_perf_flags {
	u8          reserved;             /*     0     1 */

	/* size: 1, cachelines: 1, members: 1 */
	/* last cacheline: 1 bytes */
};

Used in ctfdwdiff as in CTF land we can't express such sillyness.

Arnaldo Carvalho de Melo 57127d45fc pahole: Introduce --flat_array 
CTF doesn't have support for multiple array dimensions, so it flattens
the arrays.

This caused a large number of false positives in ctfdwdiff, so introduce
this conf_fprintf option, use it in pahole and ctfdwdiff.

Arnaldo Carvalho de Melo 45255ec6b6 pahole: Add --format_path/-F to specify a list of formats to try 
For a file with just DWARF info:

$ pahole -F ctf build/pahole
$

But if we ask that it also try dwarf:

$ pahole -F ctf,dwarf build/pahole | head -2
struct _IO_FILE {
	int          _flags;    /*     0     4 */
$

Useful when testing the new CTF support in these tools, as we'll be able to,
from the DWARF info in objects, generate the CTF equivalent and add to the same
object, then run pahole -A -F ctf, pahole -A -F dwarf and compare the outputs.
