* tests/plugins/insn: made arg inline not positional and parse it as boolMahmoud Mandour2021-09-021-2/+12
| | | | | | | | | | | | | Made argument "inline" not positional, this has two benefits. First is that we adhere to how QEMU passes args generally, by taking the last value of an argument and drop the others. And the second is that this sets up a framework for potentially adding new args easily.

* tests/plugin: expand insn test to detect duplicate instructionsAlex Bennée2021-02-181-1/+11
| | | | | | | | | | | | | | | | | | A duplicate insn is one that is appears to be executed twice in a row. This is currently possible due to -icount and cpu_io_recompile() causing a re-translation of a block. On it's own this won't trigger any tests though. The heuristics that the plugin use can't deal with the x86 rep instruction which (validly) will look like executing the same instruction several times. To avoid problems later we tweak the rules for x86 to run the "inline" version of the plugin. This also has the advantage of increasing coverage of the plugin code (see bugfix in previous commit).

* tcg plugins: expose an API version conceptAlex Bennée2019-11-121-0/+2
| | | | | | | | | | | | This is a very simple versioning API which allows the plugin infrastructure to check the API a plugin was built against. We also expose a min/cur API version to the plugin via the info block in case it wants to avoid using old deprecated APIs in the future.
