[go-nuts] Re: Go on AIX

[Tony . Reix]

The first (alpha) version of Gcc Go for AIX 7.1 is available on 
BullFreeware:

  http://bullfreeware.com/affichage.php?id=3614 

It is an experimental version. That means that still several Go compiler 
and Go libgo tests are still failing and only 32 bit version has been 
built/tested in depth for now.
Gcc Go compiler tests : still 13 AIX-specific tests out of 7346 are still 
failing.
libgo test: about 17 failing tests out of 145

GCC v7 snapshot 20170323
Go v1.8

Failures deal with: , networking, linking issue with type, etc.
If you have a message like: "value of type string is not assignable to type 
string", showing that types are considered to be different though the same, 
try linking with: -static-libgo

However, this GCC Go compiler/runtime has been used for compiling/testing a 
real Go product, FileBeat, with success.

Feel free to experiment with it.

Hi,

We are making progress with GCC Go on AIX 6.1, with GCC 7 snapshot.
Current issues are:
 - '$' character in assembler symbols. Replacing '$' by '_' is not a 
complete solution yet. Requires more study.
 - go command failure, due to: 'FFI Go closure' not being implemented on 
AIX yet.
 - still many errors in libgo tests
Help is welcome.
And we plan to share our patches starting next week.
We are now checking our patches under FedoraCore25/PPC64 (BE) .
Our plan is to bootstrap GoLang with GCC Go.

Regards
Tony

 OK, so simple object reader is completed. If you have some time, you 
 can try
 building gccgo on AIX and fix build problems as they appear.

 sorry, i can't provide more details because based on my past 
 experiences,
 different systems have vastly different problems to solve. You can ask 
 on the
 mailing list when problem arises. (But please be prepared to upstream 
 your
 changes if you do want to tackle this)
