[Bug target/25932] New: Gnat bug in simplify_subreg, at simplify-rtx.c:3746

["alex at milivojevic dot org" <gcc-bugzilla at gcc dot gnu dot org>]

I don't know anything about Ada, just happen to have gnat installed on my
system, and got this while compiling ncurses (ncurses-5.5.tar.gz, ncurses
configured with "../configure --with-shared --with-rpath --prefix=/opt/pbl"):

$ gcc -v -save-temps -c -I../../../Ada95/src/ -O3 -gnatpn -I.
-I../../../Ada95/src -I- ../../../Ada95/src/terminal_interface-curses.adb
Using built-in specs.
Target: sparc-sun-solaris2.6
Configured with: ../configure --prefix=/opt/pbl --with-local-prefix=/opt/pbl
--with-cpu=ultrasparc --with-tune=ultrasparc
--enable-languages=c,ada,c++,f95,java,objc --disable-nls --with-gmp=/opt/pbl
--with-mpfr=/opt/pbl --with-gnu-ld --with-gnu-as --with-ld=/opt/pbl/bin/ld
--with-as=/opt/pbl/bin/as --enable-java-awt=xlib --with-x
Thread model: posix95
