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