| 2 | # Sed script to parse CPP macros and generate output usable by make |
| 3 | # |
| 4 | # It is expected that this script is fed the output of 'gpp -dM' |
| 5 | # which preprocesses the common.h header files and outputs the final |
| 6 | # list of CPP macros (and whitespace is sanitized) |
| 7 | # |
| 8 | |
| 9 | # Only process values prefixed with #define CONFIG_ |
| 10 | /^#define CONFIG_[A-Za-z0-9_]\+/ { |
| 11 | # Strip the #define prefix |
| 12 | s/#define *//; |
| 13 | # Change to form CONFIG_*=VALUE |
| 14 | s/ \+/=/; |
| 15 | # Drop trailing spaces |
| 16 | s/ *$//; |
| 17 | # drop quotes around string values |
| 18 | s/="\(.*\)"$/=\1/; |
| 19 | # Concatenate string values |
| 20 | s/" *"//g; |
| 21 | # Wrap non-numeral values with quotes |
| 22 | s/=\(.*\?[^0-9].*\)$/=\"\1\"/; |
| 23 | # Change '1' and empty values to "y" (not perfect, but |
| 24 | # supports conditional compilation in the makefiles |
| 25 | s/=$/=y/; |
| 26 | s/=1$/=y/; |
| 27 | # print the line |
