156ac94463 xen-block: stop leaking memory in xen_block_drive_create()
The locally allocated QDict-s need to be freed. ('file_layer' will be
freed implicitly since it is added as an object to 'driver_layer').

Spotted by Coverity: CID 1398649

While in the neighbourhood free 'driver' and 'filename' as soon as they are
added to the QDicts. Freeing after the 'done' label doesn't make that much
sense as, if the error path jumps to that label, the values would be NULL
anyway.

This patch also makes that more obvious by taking the error path if
'params' is NULL and then asserting that both driver and filename are
non-NULL in the normal path.

2ae23f0ecf xen-block: report error condition from vbd_name_to_disk()
The function needs to make sure it is passed a valid disk name. This is
easily done by making sure that the parsing loop results in a non-zero
value.

906da88291 tests/tcg/xtensa: support configurations w/o vecbase
Configurations w/o vecbase may have vectors not grouped together and not
in fixed order. They may not always be grouped into single output
sections by assigning next offset to dot, as it may sometimes move dot
backwards and sometimes they may even belong to different memory region.
Don't group vectors into single output section. Instead put each vector
into its own section ant put it at its default virtual address.
Reserve 4KBytes from the default vectors base and put rest of the code
and data starting from there. Mark vectors sections as executable,
otherwise their contents is discarded. There may be as little as 16
bytes reserved for some vectors, load handler address into a0 and use
ret.n to jump there to make vector code fit into this 16 byte space.

068e538a54 target/xtensa: prioritize load/store in FLIX bundles
Load/store opcodes may raise MMU exceptions. Normally exceptions should
be checked in priority order before any actual operations, but since MMU
exceptions are tightly coupled with actual memory access, there's
currently no way to do it.

Approximate this behavior by executing all load, then all store, and
then all other opcodes in the FLIX bundles. Use opcode dependency
mechanism to express ordering. Mark load/store opcodes with
XTENSA_OP_{LOAD,STORE} flags. Newer libisa has classifier functions that
can tell whether opcode is a load or store, but this information is not
available in the existing overlays.

89bec9e911 target/xtensa: break circular register dependencies
Currently topologic opcode sorting stops at the first detected
dependency loop. Introduce struct opcode_arg_copy that describes
temporary register copy. Scan remaining opcodes searching for
dependencies that can be broken, break them by introducing temporary
register copies and record them in an array. In case of success
create local temporaries and initialize them with current register
values. Share single temporary copy between all register users. Delete
temporaries after translation.

b0b24bdcd9 target/xtensa: reorganize register handling in translators
To support circular register dependencies in FLIX bundles opcode inputs
and outputs must be separate and adjustable. Circular dependencies can
be broken by making temporary copies of opcode inputs and substituting
them into the arguments array instead of the original registers.

E.g. the circular register dependency in the following bundle:

  { mov a2, a3 ; mov a3, a2 }

can be resolved by making copy a2' = a2 and substituting it as input
argument of the second opcode:

  { mov a2, a3 ; mov a3, a2' }

Change opcode translator prototype to accept OpcodeArg array as
argument. For each register argument initialize OpcodeArg::{in,out} with
TCGv_* of the respective register. Don't explicitly use cpu_R in the
opcode translators, use OpcodeArg::{in,out} instead.

8df3fd3596 target/xtensa: move WINDOW_BASE SR update to postprocessing
Opcodes that modify WINDOW_BASE SR don't have dependency on opcodes that
use windowed registers. If such opcodes are combined in a single
instruction they may not be correctly ordered. Instead of adding said
dependency use temporary register to store changed WINDOW_BASE value and
do actual register window rotation as a postprocessing step.
Not all opcodes that change WINDOW_BASE need this: retw, rfwo and rfwu
are also jump opcodes, so they are guaranteed to be translated last and
thus will not affect other opcodes in the same instruction.

20e9fd0fc0 target/xtensa: sort FLIX instruction opcodes
Opcodes in different slots may read and write same resources (registers,
states). In the absence of resource dependency loops it must be possible
to sort opcodes to avoid interference.

Record resources used by each opcode in the bundle. Build opcode
dependency graph and use topological sort to order its nodes. In case of
success translate opcodes in sort order. In case of failure report and
raise invalid opcode exception.
