4
# flags and determines various statistics.

# -llf
10
# Filter out long lines from the bootstrap output before any other
11
# action.  This is useful for systems with broken awks/greps which choke
12
# on long lines.  It is not done by default as it sometimes slows things
13
# down.
14

15
# -s number
16
# Take warnings from stage "Number".  Stage 0 means show warnings from
17
# before and after the gcc bootstrap directory.  E.g. libraries, etc.
18
# This presupposes using "gcc -W*" for the stage1 compiler.
19
#
20
# -nosub
21
# Only show warnings from the gcc top level directory.
22
# -ch|-cp|-f|-fortran|-java|-ada|-intl|-fixinc
23
# Only show warnings from the specified gcc subdirectory.
24
# These override each other so only the last one passed takes effect.
25
#
26
# -pass
27
# Pass through the bootstrap output after filtering stage and subdir
28
# (useful for manual inspection.)  This is all lines, not just warnings.
29
# -wpass
30
# Pass through only warnings from the bootstrap output after filtering
31
# stage and subdir.
