The bootstrap started this morning got a little further:
stage1/xgcc -Bstage1/ -B/opt/gnu64/gcc/gcc-3.5.0/hppa64-hp-hpux11.11/bin/ -c -
g -O2 -DIN_GCC -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototyp
es -Werror -fno-common -DHAVE_CONFIG_H -I. -Ijava -I../../gcc/gcc -I../../g
cc/gcc/java -I../../gcc/gcc/../include -I../../gcc/gcc/../libcpp/include -I../..
/gcc/gcc/../libbanshee/libcompat -I../../gcc/gcc/../libbanshee -I../../gcc/gcc/.
./libbanshee/points-to ../../gcc/gcc/java/class.c -o java/class.o
../../gcc/gcc/java/class.c: In function `ident_subst':
../../gcc/gcc/java/class.c:274: internal compiler error: in emit_group_load, at
expr.c:1879
So, this one may be fixed. Regarding the timing of the failure, it was
possible to bootstrap sucessfully after the following patch was installed:
2004-06-21 John David Anglin <dave.anglin@nrc-cnrc.gc.ca>
R rtl-optimization/14782
* pa.c (emit_move_sequence): Use SFmode for 4-byte modes when doing
...
Should I open a new PR?
