When building for 32-bit host platform, some warnings are triggered and build fail. Thus, at the time, the decision was to not fix those plugins, and disable by default plugins for 32-bit host platforms (see cf2a78cb). This series fix plugins to have the same behaviour on 32-bit and 64-bit platform, and reenable plugins for 32-bit platforms. There are two portability issues: - we use hash tables, and use data as key directly. As key has a pointer size, it limits its size for 32-bit platform. The fix is to use pointer as a key, and point to allocated 64-bit data. The change is pretty straightforward for concerned plugins, and does not imply a memory overhead, as hash table entry is already heap allocated usually. - we use plugins callback data to pass a pc. This does not work on 32-bit platform, as we are limited to a pointer size. To avoid doing memory allocations, we simply we simply use inline operations and a scoreboard to achieve the same result. Tested (for every plugin modified) on i686 and x86_64. The behaviour before and after this series was checked as well, and there is no difference, apart from bug fixing (some pc were clipped at 32-bit values, even on the 64-bit platform). v2: - do not modify qemu_plugin_insn_haddr signature - fix cache plugin to use a correct hash/equal function Pierrick Bouvier (11): tests/tcg/plugins/insn: remove unused callback parameter contrib/plugins/howvec: ensure we don't regress if this plugin is extended tests/tcg/plugins/syscall: fix 32-bit build tests/tcg/plugins/mem: fix 32-bit build contrib/plugins/stoptrigger: fix 32-bit build contrib/plugins/cache: fix 32-bit build contrib/plugins/hotblocks: fix 32-bit build contrib/plugins/cflow: fix 32-bit build contrib/plugins/hwprofile: fix 32-bit build contrib/plugins/hotpages: fix 32-bit build configure: reenable plugins by default for 32-bit hosts configure | 21 +-------------- contrib/plugins/cache.c | 18 +++++-------- contrib/plugins/cflow.c | 17 ++++++++----- contrib/plugins/hotblocks.c | 29 +++++++++++++++++---- contrib/plugins/hotpages.c | 6 ++--- contrib/plugins/howvec.c | 7 ++--- contrib/plugins/hwprofile.c | 27 ++++++++++++-------- contrib/plugins/stoptrigger.c | 48 ++++++++++++++++++++--------------- tests/tcg/plugins/insn.c | 4 +-- tests/tcg/plugins/mem.c | 6 ++--- tests/tcg/plugins/syscall.c | 6 ++--- 11 files changed, 99 insertions(+), 90 deletions(-)
