* Fix qapi code generation wrt parallel buildAvi Kivity2011-12-271-3/+24
| | | | | | | | | | | | | | | | | | Make's multiple output syntax x.c x.h: x.template gen < x.template actually invokes the command once for x.c and once for x.h (with differing $@ in each invocation). During a parallel build, the two commands may be invoked in parallel; this opens up a race, where the second invocation trashes a file supposedly produced during the first, and now in use by a dependent command. The various qapi code generators are susceptible to this; fix by making them generate just one file per invocation.

* qapi: modify visitor code generation for list iterationMichael Roth2011-10-041-2/+2
| | | | | | | | | | | | Modify logic such that we never assign values to the list head argument to progress through the list on subsequent iterations, instead rely only on having our return value passed back in as an argument on the next call. Also update QMP I/O visitors and test cases accordingly, and add a missing test case for QmpOutputVisitor.

* qapi: add qapi-visit.py code generatorMichael Roth2011-07-211-0/+246
This is the code generator for qapi visiter functions used to marshal/unmarshal/dealloc qapi types. It generates the following 2 files: $(prefix)qapi-visit.c: visiter function for a particular c type, used to automagically convert qobjects into the corresponding C type and vice-versa, and well as for deallocation memory for an existing C type $(prefix)qapi-visit.h: declarations for previously mentioned visiter functions $(prefix) is used as decribed for qapi-types.py Signed-off-by: Michael Roth <mdroth@linux.vnet.ibm.com> Signed-off-by: Luiz Capitulino <lcapitulino@gmail.com>
