Ok, I see. Let me first integrate everything done so far in trunk,
then
we can continue with the details :)


I've noticed GCC uses the SLLI + SRAI instructions to perform sign 
extension on ESP8266.


Since different CPUs can support different subsets of the Xtensa 
instructions do you think a finalizecode type function can be used as 
a post code generation step to map unsupported instructions to 
alternative sequences?


These are simply different CPU types (-CpXXX or selected by the 
controller type) which the code generator will handle accordingly. Just 
like it's done with ARM, AVR and all other platforms.

Sven

Re: [fpc-devel] FPC 3.2.0RC1 released!

[Joao Schuler]

Just tested with my own neural networks API and I can confirm that it works!
Environment: WIN10 64bits AVX

Tested with:
https://github.com/joaopauloschuler/neural-api/blob/master/examples/SimpleImageClassifier/SimpleImageClassifier.lpr


In this test, there is a performance gain (speed) against 3.0.4 at about 9%.

Congrats!

In this case just cgcpu can be adapted to generate the right code. This 
results normally in better code.

  Michael,

  I remember that I was also asking why you did not put the shared lib
into the lib/fpc/3.2.0/lib subdirectory, but I forgot your explanation...

You can help improve the upcoming 3.2.0 release by downloading and
testing this release. If you want you can report what you have done

It seems libpas2jslib.so needs some adjustments under debian:

From lintian:

Errors:
unstripped-binary-or-object usr/lib/libpas2jslib.so
library-not-linked-against-libc usr/lib/libpas2jslib.so


This one is not really fixable, that's simply a bug in debian.

Michael.
