Version 3 changes the --dump option to --fulldump and --diffdump,
after an off-hand suggestion by Alex.
These are now mode options, similar to --master. Which means that
dumping is an orthogonal apprentice type, which means that we can
dump from a socket. I'm not sure that will be useful as such, but
I think it makes main be a bit cleaner.
If using old trace files with the new risu, you get
Unexpected magic number: 0x000078
If for somehow you use different risu for master and apprentice on
sockets, the apprentice will hang waiting for data that the master
will never write. This is less than helpful, but should be trivial
to avoid.
While cleaning up the interface for reginfo_dump_mismatch(), I
noticed some bugs on the ppc64 side.
The patches without reviews are:
0014-Merge-reginfo.c-into-risu.c.patch
0015-Rearrange-reginfo-and-memblock-buffers.patch
0016-Split-out-recv_register_info.patch
0017-Add-magic-and-size-to-the-trace-header.patch
0018-Compute-reginfo_size-based-on-the-reginfo.patch
0019-aarch64-Reorg-sve-reginfo-to-save-space.patch
0020-aarch64-Use-arch_init-to-configure-sve.patch
0021-ppc64-Use-uint64_t-to-represent-double.patch
0022-Standardize-reginfo_dump_mismatch-printing.patch
0023-Add-fulldump-and-diffdup-options.patch
0024-Remove-return-value-from-reginfo_dump.patch
0025-ppc64-Clean-up-reginfo-handling.patch
most of which are new, and those that aren't new have had
significant modifications.
