Bug ID: 40678
Summary: llvm-config generates options that are incompatible
with clang++
Product: clang
Version: 7.0
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: Driver

Output from "llvm-config --cxxflags"
I have a minimal C++ file (named test.cc), and I try to compile it with clang++
and llvm-config.
I run the command:
clang++ `llvm-config --cxxflags` test.cc
This command fails with the error:
clang-7: error: unknown argument: '-fstack-clash-protection'
If I run "llvm-config --cxxflags" alone I see that the problematic option is
indeed part of the output. The full output is attached.
I believe this is an error, and that the options generated by the llvm-config
command should all be accepted by the clang++ command.
Additional information:
I can compile the given file test.cc without problems if I don't invoke
llvm-config, i.e. the following command works without error:
clang++ test.cc
The versions I'm using are: 7.0.1 for both clang++ and llvm-config.
I'm using Fedora 29 (64-bit).
P.S. This is all part of a large project (not my own) on github
(https://github.com/ghdl/ghdl).
