+Subject: [PATCH] cmake: Do not add -msse4.2 -mpclmul on clang
+
+When testcase is compiled with clang and -msse4.2 -mpclmul is added to
+cxxflags then clang -m32 still ends up compiling the test case which is
+not correct for i386, therefore depend on yocto to pass the right flags
+from environemnt via cflags rather than manufecture them here
+
+Upstream-Status: Inappropriate [OE-Specific]
