[Git][cmucl/cmucl][issue-446-use-cc-to-get-errno] Use awk script to get errno values

Raymond Toy pushed to branch issue-446-use-cc-to-get-errno at cmucl / cmucl Commits: 7ef852b9 by Raymond Toy at 2025-11-03T13:33:13-08:00 Use awk script to get errno values Use an awk script in create-errno.sh to find the errno values and print them out. (Script from @cshapiro, slightly modified by me with some comments.) Update errno-template.lisp to remove the `def-unix-error` stuff since we can just use a plain `defconstant`. Don't need `export`s anymore because the UNIX package is guaranteed to export all the correct errno symbols since the export list is determined from the errno list. Regenerate errno-linux.lisp. Update errno-default.lisp to replace `def-unix-error` with `defconstant` since `def-unix-error` no longer exists. - - - - - 4 changed files: - bin/create-errno.sh - bin/errno-default.lisp - bin/errno-linux.lisp - bin/errno-template.lisp Changes: ===================================== bin/create-errno.sh ===================================== @@ -91,9 +91,30 @@ find_errno () # values in different orders. echo '#include <errno.h>' | cpp -dM - | - grep "#define[ \t]\{1,\}E[A-Z0-9]\{1,\}" | - sed 's/#define \(.*\) \(.*\)$/(def-unix-error \1 \2)/' | - sort -nr -k 3 + awk "BEGIN { + max = 0 +} +/* Pattern is '#define Efoo number' */ +/^#define[ \t]+(E[A-Z0-9]+)[ \t]+([0-9]+)/ { + errno[\$3] = \$2 + max = (\$3 > max) ? \$3 : max +} +/* Pattern is '#define Efoo Ealias' */ +/^#define[ \t]+(E[A-Z0-9]+)[ \t]+(E[A-Z0-9]+)/ { + alias[\$3] = \$2 +} +END { + /* Print out each errno and print the alias right after the actual value */ + for (i = 0; i <= max; i++) { + if (i in errno) { + printf \"(defconstant %s %d)\n\", errno[i], i + if (errno[i] in alias) { + printf \"(defconstant %s %s)\n\", alias[errno[i]], errno[i] + } + } + } +}" + } if [ "$UPDATE" = "yes" ]; then ===================================== bin/errno-default.lisp ===================================== @@ -1,94 +1,94 @@ ;;; Default errno values.
