# Usage: symbolstore.py <params> <dump_syms path> <symbol store path>
|
|
# <debug info files or dirs>
|
|
# Runs dump_syms on each debug info file specified on the command line,
|
|
# then places the resulting symbol file in the proper directory
|
|
# structure in the symbol store path. Accepts multiple files
|
|
# on the command line, so can be called as part of a pipe using
|
|
# find <dir> | xargs symbolstore.pl <dump_syms> <storepath>
|
|
# But really, you might just want to pass it <dir>.
|
|
#
|
|
# Parameters accepted:
|
|
# -c : Copy debug info files to the same directory structure
|
|
# as sym files
|
|
# -a "<archs>" : Run dump_syms -a <arch> for each space separated
|
|
# cpu architecture in <archs> (only on OS X)
|
|
# -s <srcdir> : Use <srcdir> as the top source directory to
|
|
# generate relative filenames.
