Comment (by kgardas):
Not at all! GCC by default generates 32bit code:
{{{
ka...@silence:/tmp$ cat hello.c
int
main()
{
return 0;
}
ka...@silence:/tmp$ gcc -o hello hello.c
ka...@silence:/tmp$ file hello
hello: ELF 32-bit LSB executable 80386 Version 1 [FPU], dynamically
linked, not stripped, no debugging information available
ka...@silence:/tmp$
}}}
In addition this define is not defined by default, but when you use -m64
option. Then it's used. BTW: I'm also a little bit confused by the fact
that when I invoke config.guess from the command-line it claims it's
running on i386-pc-solaris, but if I run ./configure then it shows x86_64
-unknown-solaris...

Till now using older version of config.guess my amd64/solaris box was recognized as i386-solaris and GHC behaves accordingly and builds well (for i386-solaris2). Since your config.guess update, GHC knows it's configured on amd64-solaris and complains about unsupported platform. So my fix is natural fix to make GHC again believe this is i386-solaris as it supports it all the time. Of course it's very easy for anyone interested just to revert this simple patch and hack on real amd64-solaris platform support.

So Solaris supports 2 ABIs, provides gcc 3.4.3 which by default generates 32bit code for i386 ABI. It might be also used to generate 64bit code for amd64 ABI if started with -m64 command-line option. If I'm right, then for GHC build, we do have i386 ABI GHC for Solaris in binary form and so stage1 compiler should also be compiled for i386, but it should be a cross-compiler run on i386 generating code for amd64 ABI. Stage2 compiler should then be amd64 ABI and also in stage2 build and rts build executed gcc should be used with -m64 option to get 64bit binary. Now, the question is just where to hack to make it real. :-) (if I'm right of course) -- Ticket URL: http://hackage.haskell.org/trac/ghc/ticket/2951#comment:7 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler___ Glasgow-haskell-bugs mailing list Glasgow-haskell-bugs@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-bugs

I updated `config.guess`, so the platform will now be recognised. There's
still a lot to do to support this platform, though.

Hello,
it would be nice if GHC build correctly detects if it's running on amd64
platform or plain old i386 platform. The problem is that current
config.guess returns in both cases i386-pc-solaris2.* string. Certainly
there is a possibility to use `isainfo -n` to test for application
supported instruction set, see:
{{{
ka...@silence:~/vcs/ghc$ ./config.guess
i386-pc-solaris2.11
ka...@silence:~/vcs/ghc$ isainfo -n
amd64
ka...@silence:~/vcs/ghc$
}}}
I'm just not sure if hacking configure.ac's code below
{{{
i[[3456]]86-*-solaris2*)
HostPlatform=i386-unknown-solaris2 # hack again
TargetPlatform=i386-unknown-solaris2
BuildPlatform=i386-unknown-solaris2
HostPlatform_CPP='i386_unknown_solaris2'
HostArch_CPP='i386'
HostVendor_CPP='unknown'
HostOS_CPP='solaris2'
;;
}}}
and changing HostArch_CPP from 'i386' to 'x86_64' would be enough for the
change.
