[Bug rtl-optimization/37782] [4.4 regression] Stage2 ada compiler miscompiled

[doko at ubuntu dot com]

------- Comment #1 from doko at ubuntu dot com  2008-10-13 05:13 -------
seen as well with a powerpc biarch compiler, defaulting to powerpc-linux-gnu.
reverting this patch lets the build continue, but fails later with:

/build/buildd/gcc-snapshot-20081012/build/./prev-gcc/xgcc
-B/build/buildd/gcc-snapshot-20081012/build/./prev-gcc/
-B/usr/lib/gcc-snapshot/powerpc-linux-gnu/bin/ -c -g -O2  -gnatpg -gnata
-nostdinc -I- -I. -Iada -I../../src/gcc/ada -I../../src/gcc/ada/gcc-interface
../../src/gcc/ada/switch.adb -o ada/switch.o
