# GCC bootstrap support

-# So in the building rule for each stage, we relocate them before and after.
-# The current one is 'gcc', while the previous one is 'prev-gcc'. (The
-# current one must be 'gcc' for now because the scripts in that directory
-# assume it.)
-# At the end of the bootstrap, 'stage3-gcc' must be moved to 'gcc' so that

+# We track the current stage (the one in 'gcc') in the stage_last file.
+# We name the build directories for the various stages "stage1-gcc",
+# "stage2-gcc","stage3-gcc", etc.
+
+# Since the 'compare' process will fail (on debugging information) if any
+# directory names are different, we need to link the gcc directory for
+# the previous stage to a constant name ('gcc-prev'), and to make the name of
+# the build directories constant as well. For the latter, we use naked names
+# like 'gcc', because the scripts in that directory assume it. We use

+# At the end of the bootstrap, a symlink to 'stage3-gcc' named 'gcc' must
