17# This script is used to transform the dependency files generated by GCC
18# For example, a typical .d file will have a line like:
19#
20#    source.o: /full/path/to/source.c other.h headers.h
21#    ...
22#
23# the script is used to replace 'source.o' to a full path, as in
24#
25#    objs/intermediates/emulator/source.o: /full/path/to/source.c other.h headers.h
26#
27# parameters
28#
29# $1: object file (full path)
30# $2: source dependency file to modify (erased on success)
31# $3: target source dependency file
32#
33
34# quote the object path. we change a single '.' into
35# a '\.' since this will be parsed by sed.
36#
37OBJECT=`echo $1 | sed -e s/\\\\./\\\\\\\\./g`
38#echo OBJECT=$OBJECT
39
40OBJ_NAME=`basename $OBJECT`
41#echo OBJ_NAME=$OBJ_NAME
42
43# we replace $OBJ_NAME with $OBJECT only if $OBJ_NAME starts the line
44# that's because some versions of GCC (e.g. 4.2.3) already produce
45# a correct dependency line with the full path to the object file.
46# In this case, we don't want to touch anything
47#
48cat $2 | sed -e s%^$OBJ_NAME%$OBJECT%g > $3 && rm -f $2
