Thanks.
The cross-compiler we use is gcc 4.9.3. But also the native gcc
on my Sun Voyager running Debian 4.0 have it:
platin:~# gcc -dM -E - </dev/null|grep sparc
#define sparc 1
#define __sparc__ 1
#define __sparc 1
#define __sparc_v8__ 1
platin:~# gcc -v
Using built-in specs.
Target: sparc-linux-gnu
Configured with: ../src/configure -v
--enable-languages=c,c++,fortran,objc,obj-c++,treelang --prefix=/usr
--enable-shared --with-system-zlib --libexecdir=/usr/lib
--without-included-gettext --enable-threads=posix --enable-nls
--program-suffix=-4.1 --enable-__cxa_atexit --enable-clocale=gnu
--enable-libstdcxx-debug --enable-mpfr --with-cpu=v8
--enable-checking=release sparc-linux-gnu
Thread model: posix
gcc version 4.1.2 20061115 (prerelease) (Debian 4.1.1-21)
platin:~# cat /etc/debian_version
4.0
The last supported Debian is delivering Postgresql 7.5.22.
I think this version did not contained the code:
platin:~/postgresql-7.5.22# find . -name \*lock.h
platin:~/postgresql-7.5.22# grep -r sparc *
So may be buildroot is one of the few projects supporting sparcv8
for 32 Bit sparc machines.
