Dear all,
this is the rebase of version 4 of this series that adds enhanced tracking of
IF/ELSE
branches and tracking of reladdr* registers for the register_merge step.
It cleans up the debugging output and moves the testing classes into a
conveniance
library. The latter is in preparation for another series that will deal with
array
merging.
The series shows no piglit regressions and I use it already for quite some time.
So far patches 3 (was 1 in v3) and 8 (was 5 in v1)
Reviewed-by: Nicolai Hähnle <nicolai.haeh...@amd.com>
Changes w.r.t. v3:
* Add patch 1: mesa/program: Add missing file types to _mesa_register_file_name
* Ass patch 2: Add stream and equal operators and rewrite the debug output to
use the stream operator and _mesa_register_file_name instead of some
hand backed code and squeash former patch 5 into this.
* Move the Mock* classes and shared test code into a conveniance
library, and rename Mock* to Fake* since they are not really Mocks.
Changes w.r.t. v2:
* patch 9: make the creation of register description tuples explicit because
this is what in c++11 is actually required (This slipped before because it
seems that g++-7.2 handles tuple initialization like it was c++17, also with
its default setting -std=c++14).
v1:
* patches 2-4(new): As suggested by Nikolai, these patches unify the test
classes
with respect to the different register inputs (at this point: plain and with
swizzle). In addition, some comments are corrected and the used of white
spaces
in the test cases is made more consistent.
* patch 5: correct the debug output for indirect addressing. Nikolai suggested
that
another patch might be in order to properly propagate the information when
and
which address register is used, but since st_*_reg is passed through various
levels by value, I'd prefer to deal with that in another, dedicated patch
series.
* patch 6: Further improve the tracking algorithm, and, as requested by Nikolai,
rename some variables and add comments to make the algorithm clearer.
* patch 7: Add yet more tests.
* patch 9: Update the tests to adhere to the new, unified interface.
* patch 10 (new): remove the no longer needed assert for the use of address
registers
in register_merge (I was considering to add this to 8, but since that one was
already
reviewed ...)
many thanks for any comments,
Gert
