Hi,
I'm getting a stack overflow caused by *very* deep recursion while trying to
build gnu/javax/swing/text/html/parser/HTML_401F.o in libjava, bootstrapping
HEAD on i686-pc-cygwin.
With the default per-thread stack size of 2MB, it crashes in
tree_ssa_phiprop_1(), which by the time of
I've run up against a problem with reusing the GNAT trees:
Apparently during semantic analysis entity names are expanded
to their fully qualified names in the tree.
For example, when compiling the following file with the node
for System already installed by a previous compilation,

Many Linux distros compile binaries for a common lowest denominator so that you
could run a distro on very old computers and CPUs - their developers in most
cases choose -march=i686 or -march=i586.

For better speed with -march=pentium2 you should add -mtune=generic which
will use only pentium2 features but tunes the code to not pessimize newer

the following code:

spurious code differences across runs of GCC. I saw this, for example, in
