描述
Optoion '--entry' ('--entry=') should be forwarded to linker the same way as its aliasee '-e' is forwarded. Currently, it complains about unsupported option.
clang test.c --entry=my_start
clang: error: unsupported option '--entry=my_start'
Apparently, the option is declared as a flag, i.e. clang accepts this, but linker non-surprisingly fails:
clang test.c --entry
/usr/bin/ld: warning: cannot find entry symbol --library=gcc; defaulting to 0000000000001040
