c74824389e tcg: Fix indirect lowering vs TCG_OPF_COND_BRANCH
With TCG_OPF_COND_BRANCH, we extended the lifetimes of
globals across extended basic blocks.  This means that
the liveness computed in pass 1 does not kill globals
in the same way as normal temps.

Introduce TYPE_EBB to match this lifetime, so that we
get correct register allocation for the temps that we
introduce during the indirect lowering pass.

4e51069d67 util/log: Support per-thread log files
Add a new log flag, tid, to turn this feature on.
Require the log filename to be set, and to contain %d.

Do not allow tid to be turned off once it is on, nor let
the filename be change thereafter.  This avoids the need
for signalling each thread to re-open on a name change.

30f5a73ac3 util/log: Limit RCUCloseFILE to file closing
Use FILE* for global_file.  We can perform an rcu_read on that
just as easily as RCUCloseFILE*.  This simplifies a couple of
places, where previously we required taking the rcu_read_lock
simply to avoid racing to dereference RCUCloseFile->fd.

Only allocate the RCUCloseFile prior to call_rcu.

really need to close the FILE before the abort.

The two uses in test-logging.c can be handled with
qemu_set_log_filename_flags.

eecb0c4e11 target/hexagon: Remove qemu_set_log in hexagon_translate_init
This code appears to be trying to make sure there is a logfile.
But that's already true -- the logfile will either be set by -D,
or will be stderr.  In either case, not appropriate here.

54ee5b3da0 util/log: Drop manual log buffering
This buffering was introduced during the Paleozoic: 9fa3e85353.

There has never been an explanation as to why we may not allow
glibc to allocate the file buffer itself.  We certainly have
many other uses of mmap and malloc during user-only startup,
so presumably whatever the issue was, it has been fixed during
the preceeding 18 years.

caccf59918 tests/guest-debug: better handle gdb crashes
There are a number of GDB's on various distros which fail fairly hard
when attempting to talk to a cross-arch guest. The previous attempt to
catch this was incorrect as the shell will deliver signals as 128+n.
Fix the detection and while we are it improve the logging we dump into
the test output.

e618e1f9b4 target/i386: fix byte swap issue with XMM register access
During the conversion to the gdb_get_reg128 helpers the high and low
parts of the XMM register where inadvertently swapped. This causes
reads of the register to report the incorrect value to gdb.
