Bug ID: 20977
Summary: UniversalDriver incorrectly removes the -flavor /
-core switches from its command line
Product: lld
Version: unspecified
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P

UniversalDriver.cpp, the getFlavor function.
When UniversalDriver finds -core or -flavor switch, it tries to remove it from
the command line so that it is not passed to the underlying drivers, such as
the GnuLdDriver. The removal logic is incorrect.
E.g., UniversalDriver does the following to remove -core:
argv++;
argc--;
There are two problems with that:
1) the switch does not necessarily go first in the command line - it can be in
the middle or at the end;
2) this ignores the fact that argv[0] is actually the program name, not a
switch or an option. Program name is skipped instead.
