Bug ID: 15327
Summary: clang warns of unused argument '--param
ssp-buffer-size=1' when linking but not compiling
Product: clang
Version: 3.2
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: Frontend
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Classification: Unclassified
$ clang --param ssp-buffer-size=1 foo.c
$ clang --param ssp-buffer-size=1 -c foo.c
$ clang --param ssp-buffer-size=1 foo.o
clang: warning: argument unused during compilation: '--param ssp-buffer-size=1'
This inconsistency confuses a mosh (https://github.com/keithw/mosh) autoconf
test into thinking the flag is supported, leading to warnings (or with -Werror,
errors) emitted later in a build.
A followup to http://llvm.org/bugs/show_bug.cgi?id=9673 .
