This +causes troubles in the cscope scanner and such function definition is +dropped on the floor. + +Instead of choking and skipping the definition/declaration, teach the +scanner about this case. So now cscope will not skip those and put +them properly in the index. + +I carry this patch for a couple of months and using cscope daily on +the Linux kernel and see no problems. + +Signed-off-by: Jiri Slaby <jslaby@suse.cz> +Cc: Hans-Bernhard Bröker <broeker@users.sourceforge.net> +Cc: Neil Horman <nhorman@users.sourceforge.net> +Signed-off-by: Vladis Dronov <vdronov@redhat.com> +--- + src/fscanner.l | 2 +- + 1 file changed, 1 insertion(+), 1 deletion(-) + +diff --git a/src/fscanner.l b/src/fscanner.l +index 8a93192..43880bf 100644 +--- a/src/fscanner.l ++++ b/src/fscanner.l +@@ -505,7 +505,7 @@ if{wsnl}*\( { /* ignore 'if' */ + } + + <WAS_IDENTIFIER>{ +-{ws}*\(({wsnl}|{identifier}|{number}|[*&[\]=,.:])*\)([()]|{wsnl})*[:a-zA-Z_#{] { ++{ws}*\(({wsnl}|{identifier}|\({ws}*\*{ws}*{identifier}{ws}*\){ws}*\([^()]*\)|{number}|[*&[\]=,.:])*\)([()]|{wsnl})*[:a-zA-Z_#{] { + /* a function definition */ + /* note: "#define a (b) {" and "#if defined(a)\n#" + * are not fcn definitions! */ +-- +2.26.2 + |
