Hi,
This series converts 2000+ lines of switch() code to decodetree
description, so this hard-to-review/modify switch is auto generated
by the decodetree script. This is a big win for maintenance (and
indeed the convertion revealed 2 bugs).
Massive convertions are - beside being often boring - bug-prone.
In this series we re-start running the MSA tests (the tests are
run automagically in the 'build-user-static' job on gitlab CI).
Although boring, the conversion is very clean, so I hope it will
be easy enough to review. The TRANS*() macros are heavily used.
When possible, constant fields are hold with tcg_constant().
Note, various opcodes can be optimized using TCG host vectors.
We won't address that in this series, as it makes the resulting
review harder. We will post that in a following series. Here we
simply dummy-convert.
The resulting msa.decode file is quite pleasant to look at, and
the diff-stat is encouraging: number of LoC halved.
Regards,
Phil.
