f15380190a qapi-commands: Rearrange code
Rename gen_marshal_input() to gen_marshal(), because the generated
function marshals both arguments and results.

Rename gen_visitor_input_containers_decl() to gen_marshal_vars(), and
move the other variable declarations there, too.

Rename gen_visitor_input_block() to gen_marshal_input_visit(), and
rearrange its code slightly.

Rename gen_marshal_input_decl() to gen_marshal_proto(), because the
result isn't a full declaration, unlike gen_command_decl()'s.

New gen_marshal_decl() actually returns a full declaration.

e98859a9b9 qapi: Clean up after recent conversions to QAPISchemaVisitor
Generate just 'FOO' instead of 'struct FOO' when possible.

Drop helper functions that are now unused.

Make pep8 and pylint reasonably happy.

Rename generate_FOO() functions to gen_FOO() for consistency.

Use more consistent and sensible variable names.

Consistently use c_ for mapping keys when their value is a C
identifier or type.

Simplify gen_enum() and gen_visit_union()

Consistently use single quotes for C text string literals.

5710153e73 qapi: Replace dirty is_c_ptr() by method c_null()
is_c_ptr() looks whether the end of the C text for the type looks like
a pointer.  Works, but is fragile.

We now have a better tool: use QAPISchemaType method c_null().  The
initializers for non-pointers become prettier: 0, false or the
enumeration constant with the value 0 instead of {0}.

efd2eaa6c2 qapi: De-duplicate enum code generation
Duplicated in commit 21cd70d.  Yes, we can't import qapi-types, but
that's no excuse.  Move the helpers from qapi-types.py to qapi.py, and
replace the duplicates in qapi-event.py.

The generated event enumeration type's lookup table becomes
const-correct (see commit 2e4450f), and uses explicit indexes instead
of relying on order (see commit 912ae9c).

441cbac0c7 qapi-visit: Convert to QAPISchemaVisitor, fixing bugs
Fixes flat unions to visit the base's base members (the previous
commit merely added them to the struct).  Same test case.

Patch's effect on visit_type_UserDefFlatUnion():

     static void visit_type_UserDefFlatUnion_fields(Visitor *m, UserDefFlatUnion **obj, Error **errp)
     {
         Error *err = NULL;

    +    visit_type_int(m, &(*obj)->integer, "integer", &err);
    +    if (err) {
    +        goto out;
    +    }
         visit_type_str(m, &(*obj)->string, "string", &err);
         if (err) {
             goto out;

Test cases updated for the bug fix.

Fixes alternates to generate a visitor for their implicit enumeration
type.  None of them are currently used, obviously.  Example:
block-core.json's BlockdevRef now generates
visit_type_BlockdevRefKind().

Code is generated in a different order now, and therefore has got a
few new forward declarations.  Doesn't matter.

The guard QAPI_VISIT_BUILTIN_VISITOR_DECL is renamed to
QAPI_VISIT_BUILTIN.

The previous commit's two ugly special cases exist here, too.  Mark
both TODO.

2b162ccbe8 qapi-types: Convert to QAPISchemaVisitor, fixing flat unions
Fixes flat unions to get the base's base members.  Test case is from
commit 2fc0043, in qapi-schema-test.json:

    { 'union': 'UserDefFlatUnion',
      'base': 'UserDefUnionBase',
      'discriminator': 'enum1',
      'data': { 'value1' : 'UserDefA',
                'value2' : 'UserDefB',
                'value3' : 'UserDefB' } }

    { 'struct': 'UserDefUnionBase',
      'base': 'UserDefZero',
      'data': { 'string': 'str', 'enum1': 'EnumOne' } }

    { 'struct': 'UserDefZero',
      'data': { 'integer': 'int' } }

Patch's effect on UserDefFlatUnion:

     struct UserDefFlatUnion {
         /* Members inherited from UserDefUnionBase: */
    +    int64_t integer;
         char *string;
         EnumOne enum1;
         /* Own members: */
         union { /* union tag is @enum1 */
             void *data;
             UserDefA *value1;
             UserDefB *value2;
             UserDefB *value3;
         };
     };

Flat union visitors remain broken.  They'll be fixed next.

Code is generated in a different order now, but that doesn't matter.

The two guards QAPI_TYPES_BUILTIN_STRUCT_DECL and
QAPI_TYPES_BUILTIN_CLEANUP_DECL are replaced by just
QAPI_TYPES_BUILTIN.

Two ugly special cases for simple unions now stand out like sore
thumbs:

1. The type tag is named 'type' everywhere, except in generated C,
   where it's 'kind'.

2. QAPISchema lowers simple unions to semantically equivalent flat
   unions.  However, the C generated for a simple unions differs from
   the C generated for its equivalent flat union, and we therefore
   need special code to preserve that pointless difference for now.

Mark both TODO.

b2af43cc37 spice: surface switch fast path requires same format too.
Commit "555e72f spice: rework mirror allocation, add no-resize fast path"
adds a fast path for surface switches which does't go through the full
primary surface destroy and re-recreation in case the new surface is
identical to the old one (page-flip).  It checks the size only though,
but the format must be identical too.  This patch adds the format check.

Commit "0002a51 ui/spice: Support shared surface for most pixman
formats" increases the chance to actually trigger this.

156402e504 tests/qapi-schema: Convert test harness to QAPISchemaVisitor
The old code prints the result of parsing (list of expression
dictionaries), and partial results of semantic analysis (list of enum
dictionaries, list of struct dictionaries).

The new code prints a trace of a schema visit, i.e. what the back-ends
are going to use.  Built-in and array types are omitted, because
they're boring.

ac88219a6c qapi: New QAPISchema intermediate reperesentation
The QAPI code generators work with a syntax tree (nested dictionaries)
plus a few symbol tables (also dictionaries) on the side.

They have clearly outgrown these simple data structures.  There's lots
of rummaging around in dictionaries, and information is recomputed on
the fly.  For the work I'm going to do, I want more clearly defined
and more convenient interfaces.

Going forward, I also want less coupling between the back-ends and the
syntax tree, to make messing with the syntax easier.

Create a bunch of classes to represent QAPI schemata.

Have the QAPISchema initializer call the parser, then walk the syntax
tree to create the new internal representation, and finally perform
semantic analysis.

Shortcut: the semantic analysis still relies on existing check_exprs()
to do the actual semantic checking.  All this code needs to move into
the classes.  Mark as TODO.

Simple unions are lowered to flat unions.  Flat unions and structs are
represented as a more general object type.

Catching name collisions in generated code would be nice.  Mark as
TODO.

We generate array types eagerly, even though most of them aren't used.
Mark as TODO.

Nothing uses the new intermediate representation just yet, thus no
change to generated files.

Introduce a new form GEN_XX2FORM, which decodes AX and BX and mark
the lowest bit as invalid.

DEFINE_MACHINE() per machine registered. In cases where multiple
machines are registered from one source file, avoid the excessive
generation of module init functions by reverting this unrolling.

5eb4f645eb tcg/mips: Fix clobbering of qemu_ld inputs
The MIPS TCG backend implements qemu_ld with 64-bit targets using the v0
register (base) as a temporary to load the upper half of the QEMU TLB
comparator (see line 5 below), however this happens before the input
address is used (line 8 to mask off the low bits for the TLB
comparison, and line 12 to add the host-guest offset). If the input
address (addrl) also happens to have been placed in v0 (as in the second
column below), it gets clobbered before it is used.

     addrl in t2              addrl in v0

 1 srl     a0,t2,0x7        srl     a0,v0,0x7

13 lw      t0,0(v0)         lw      t0,0(v0)

Fix by using TCG_TMP0 (at) as the temporary instead of v0 (base),
pushing the load on line 5 forward into the delay slot of the low
comparison (line 10). The early load of the addend on line 7 also needs
pushing even further for 64-bit targets, or it will clobber a0 before
we're done with it. The output for 32-bit targets is unaffected.

6c76b37742 qdev: Do not use slow [*] expansion for GPIO creation
Expansion of [*] suffix is very slow because index expansion is done using
trial and error strategy, starting every time from zero and retrying with
the next index until insertion succeeds. With large number of already added
properties this process takes huge amount of time (O(n^2) complexity).

Some architectures (like ARM) use very large amount of IRQ pins in interrupt
controller models. This flaw makes machine startup extremely slow
(~20 seconds for ARM64 with 32 CPUs). This patch decreases this time down to
~10 seconds.

Also in qdev_init_gpio_out_named() memset() is now called only once for the
whole array instead of per-cell cleaning

e1c8237df5 qom: Fix invalid error check in property_get_str()
When a function returns a null pointer on error and only on error, you
can do

    if (!foo(foos, errp)) {
        ... handle error ...
    }

instead of the more cumbersome

    Error *err = NULL;

    if (!foo(foos, &err)) {
        error_propagate(errp, err);
        ... handle error ...
    }

A StringProperty's getter, however, may return null on success!  We
then fail to call visit_type_str().

Screwed up in 6a146eb, v1.1.

Instead of

you need to do something like

    foo(foos, &err);
