Hi,
I wrote a new pass following the examples listed in the wiki
pages. However, when I "../gcc/configure; make bootstrap", I got
error messages like:
/xgcc -B./ -B/usr/local/i686-pc-linux-gnu/bin/ -isystem
/usr/local/i686-pc-linux-gnu/include -isystem

/usr/include/bits/stdio.h:37: internal compiler error:
Segmentation fault
The pass just iterates all statements using FOR_EACH_BB and
bsi_start/bsi_next and counts the numbers of different kinds of
statements. I only added a new file containing the code for
counting and didn't touch other files except for tree-pass.h,
timevar.def, passes.c, Makefile.in which are mentioned in the
examples. There is a hash table structure written by myself in the
new file, using some library functions, such as xmalloc, assert
and strcmp. I have no clue what the error message implies. Can
anybody shed some light on it?
By the way, when I tried to build GCC using the code from the CVS
repository, the bootstrap failed on my machine, showing error
message like:
config.status: error: cannot find input file:
native/jawt/Makefile.in
configure: error: /bin/sh
'../../../../gcc/libjava/classpath/configure' failed for classpath
make[1]: *** [configure-target-libjava] Error 1
make[1]: Leaving directory `/backup/gcc/gcccvs/gccbuild'
make: *** [bootstrap] Error 2
However, if I disable Java support by
"../gcc/configure --enable-language=c,c++,fortran,objc", bootstrap
succeeds. Does it mean that certain configuration for Java is
wrong?
Thanks a lot.
