Bug #: 50589
Summary: [4.7] Ada bootstrap failure on sparc-linux
Classification: Unclassified
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: ada
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: mi...@it.uu.se
I'm attempting to bootstrap a plain sparc-linux gcc on sparc64-linux, by
passing --build=sparc-unknown-linux --host=sparc-unknown-linux
--target=sparc-unknown-linux --enable-targets=all --with-cpu=v8
--enable-multilib to configure. The build fails however in Ada:
/mnt/scratch/objdir47/./gcc/xgcc -B/mnt/scratch/objdir47/./gcc/
-B/mnt/scratch/install47/sparc-unknown-linux/bin/
-B/mnt/scratch/install47/sparc-unknown-linux/lib/ -isystem
/mnt/scratch/install47/sparc-unknown-linux/include -isystem
/mnt/scratch/install47/sparc-unknown-linux/sys-include -c -g -O2 -fPIC -W
-Wall -gnatpg s-linux.ads -o s-linux.o

The complete configuration is:
/mnt/scratch/gcc-4.7-20111001/configure --prefix=/mnt/scratch/install47
--with-gmp=/home/mikpe/pkgs/linux-sparc64/gmp-5.0.2
--with-mpfr=/home/mikpe/pkgs/linux-sparc64/mpfr-3.0.1
--with-mpc=/home/mikpe/pkgs/linux-sparc64/mpc-0.9 --disable-plugin
--disable-lto --disable-nls --enable-threads=posix --enable-checking=release
--disable-libmudflap --enable-languages=c,ada
--disable-build-poststage1-with-cxx --build=sparc-unknown-linux
--host=sparc-unknown-linux --target=sparc-unknown-linux --enable-targets=all
--with-cpu=v8 --enable-multilib
The reason I'm overriding build/host/target is that a recent change on trunk
broke the ability to build a sparc64-linux gcc that defaults to -m32, see
PR50354.
