Subject: badsymbols.pl: Add verbose mode -v
X-Git-Tag: curl-7_75_0~205
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=7f170a0f5f78b18c898911b9a234275c6e7c2d41;p=thirdparty%2Fcurl.git

badsymbols.pl: Add verbose mode -v

Use -v as the first option to enable verbose mode which will show source
input, extracted symbol and line info. For example:

Source: ./../include/curl/typecheck-gcc.h
Symbol: curlcheck_socket_info(info)
Line #423: #define curlcheck_socket_info(info)                     \

Ref: https://curl.se/mail/lib-2020-12/0084.html

Closes https://github.com/curl/curl/pull/6349
