The following changeset applies some corrections to the way system
registers are processed and presented when reading perf.data files using
the various perf tools.
The commit message from [4/4] shows how register names aren't correctly
presented when performing x-arch analysis of perf.data files (i.e.
recording in one arch, then reading the file from a different arch).
Please let me know if there are any concerns with this approach, or if
any improvements can be made for subsequent re-rolls of the changeset.
- [PATCH 1/4] Fixes a potential out-of-bounds access when reading the
values of the registers in the perf.data file.
- [PATCH 2/4] Modifies one of the callbacks in "struct scripting_ops"
so that the python version can obtain the correct register names.
- [PATCH 3/4] Adds header files with the register indices and names
from all architectures, which are used by the next patch.
- [PATCH 4/4] Refactors the function "perf_reg_name" so that it can
support registers from all architectures, not just the local one.
Thanks,
German
