This patchset refactors the risu C code to reduce the significant amount of duplicated and duplicated-but-not-quite-the-same code in the per-CPU files.
I've compile tested this for all architectures, but I'm not in a position to do runtime tests for non-ARM (my attempt to use the ppc64le risu under QEMU gives mismatch errors even without these patches, and the m68k risu makes QEMU crash, presumably because our m68k support isn't complete yet). So I wasn't quite prepared to just push it straight out to master the way I've done with previous changes I've been making. Nikunj, Laurent: if you have time to test this patchset to confirm that it hasn't broken anything for you that would be great. If not, no problem; I'll probably push it to master in a week or so and we can sort any issues with it out later as separate patches. You can find a git branch with these changes at https://git.linaro.org/people/peter.maydell/risu-dev.git cpu-refactor (nb that's not the official risu upstream repo, but a different one on the same server that I'm using for development/testing). My motivation for all this, incidentally, is that I wanted to have a go at resurrecting the x86 backend as a test case for how we should support variable-length instruction sets. I got distracted by how much duplicate code we were dealing with both in risugen and in risu itself... thanks -- PMM Peter Maydell (9): Drop the weird modification of a ucontext in the ppc reginfo_is_eq() Abstract out getting and setting parameter register Make get_risuop() a formal part of the CPU interface ppc64le, m68k: Make reginfo_dump() API match arm, aarch64 m68k: Drop unused ucontext_t* argument to reginfo_is_eq() Make reginfo_{init,is_eq,dump,dump_mismatch} official per-CPU API Move send_register_info() to reginfo.c Move recv_and_compare_register_info() and report_match_status() to reginfo.c Tidy up #include lines Makefile | 4 +- reginfo.c | 151 ++++++++++++++++++++++++++++++++++++++++++++++ risu.h | 43 ++++++++++++- risu_aarch64.c | 152 +++------------------------------------------- risu_arm.c | 159 ++++--------------------------------------------- risu_m68k.c | 136 +++--------------------------------------- risu_ppc64le.c | 136 +++--------------------------------------- risu_reginfo_aarch64.h | 12 ---- risu_reginfo_arm.h | 12 ---- risu_reginfo_m68k.c | 23 +++---- risu_reginfo_m68k.h | 12 ---- risu_reginfo_ppc64le.c | 59 ++++++++---------- risu_reginfo_ppc64le.h | 12 ---- 13 files changed, 271 insertions(+), 640 deletions(-) create mode 100644 reginfo.c -- 2.7.4
