| # Sed script to parse CPP macros and generate output usable by make |
| # |
| # It is expected that this script is fed the output of 'gpp -dM' |
| # which preprocesses the common.h header files and outputs the final |
| # list of CPP macros (and whitespace is sanitized) |
| # |
| |
| # Only process values prefixed with #define CONFIG_ |
| /^#define CONFIG_[A-Za-z0-9_][A-Za-z0-9_]*/ { |
| # Strip the #define prefix |
| s/#define *//; |
| # Change to form CONFIG_*=VALUE |
| s/ */=/; |
| # Drop trailing spaces |
| s/ *$//; |
| # drop quotes around string values |
| s/="\(.*\)"$/=\1/; |
| # Concatenate string values |
| s/" *"//g; |
| # Wrap non-numeral values with quotes |
| s/=\(.*\?[^0-9].*\)$/=\"\1\"/; |
| # Change '1' and empty values to "y" (not perfect, but |
| # supports conditional compilation in the makefiles |
| s/=$/=y/; |
| s/=1$/=y/; |
| # print the line |
| p |
