For the last few days, since April 8th, I get bootstrap failures on
mainline like this:
stage1/xgcc -Bstage1/
-B/ices/bangerth/tmp/build-gcc/gcc-install/i686-pc-linux-gnu/bin/ -c -g
-O2 -DIN_GCC -W -Wall -Wwrite-strings -Wstrict-prototypes
-Wmissing-prototypes -pedantic -Wno-long-long -Wno-variadic-macros
-Wold-style-definition -Werror -fno-common -DHAVE_CONFIG_H -I. -I.
-I../../gcc/gcc -I../../gcc/gcc/. -I../../gcc/gcc/../include
-I../../gcc/gcc/../libcpp/include ../../gcc/gcc/tree-ssa-pre.c -o
tree-ssa-pre.o
../../gcc/gcc/tree-ssa-pre.c: In function 'execute_pre':
../../gcc/gcc/tree-ssa-pre.c:1812: sorry, unimplemented: inlining failed in call to 'create_value_expr_from': recursive inlining
../../gcc/gcc/tree-ssa-pre.c:1853: sorry, unimplemented: called from here
make[1]: *** [tree-ssa-pre.o] Error 1
The failure happens in a piece of code that was added here:
http://gcc.gnu.org/ml/gcc-bugs/2005-04/msg00337.html
by Dan Berlin (it introduced the recursive calls), though it certainly
isn't the cause, just the trigger. It also was added already April 4th.
Since this has been happening for the last 10 days for me, I start to
believe that I may be the only one seeing this. Anyone any explanations?
Thanks
Wolfgang
PS: System is "Linux terra.ices.utexas.edu 2.4.25-13mdkenterprise #1 SMP
Tue Jan 18 14:02:17 MST 2005 i686 unknown unknown GNU/Linux", the
bootstrap compiler is Mandrake's gcc 3.3.2.
