Summary: Don't complain about '-g' in link commands
Product: clang
Version: unspecified
Platform: PC
OS/Version: All
Status: NEW
Severity: normal
Priority: P
Component: Driver
AssignedTo: [email protected]
ReportedBy: [email protected]

$ clang --version
clang version 2.9 (trunk 119002)
Target: x86_64-unknown-linux-gnu
Thread model: posix
$ echo "int main() { return 0; }" | clang -xc - -c -o main.o
$ clang -g main.o
clang: warning: argument unused during compilation: '-g'
The warning is a lie (no compilation is happening).
It is also annoying.
It also causes many GDB testsuite "unresolved" outcomes, because
TCL/runtest/expect thinks that if a command produced stderr output,
then the command failed:
$ expect
expect1.1> exec clang -g main.o
clang: warning: argument unused during compilation: '-g'
while executing <<< this indicates TCL exception
"exec clang -g main.o"
expect1.2> exec /bin/true
expect1.3> exec /bin/false
child process exited abnormally
while executing
"exec /bin/false"
expect1.4>
