| 4 | Subject: [PATCH] cmake: Do not add -msse4.2 -mpclmul on clang |
| 5 | |
| 6 | When testcase is compiled with clang and -msse4.2 -mpclmul is added to |
| 7 | cxxflags then clang -m32 still ends up compiling the test case which is |
| 8 | not correct for i386, therefore depend on yocto to pass the right flags |
| 9 | from environemnt via cflags rather than manufecture them here |
| 10 | |
| 11 | Upstream-Status: Inappropriate [OE-Specific] |
