Hi,

Ternary operator with vector does not work with Apple Clang:

bitmac-mini:tmp abique$ clang++ -std=c++17 clang-ternary-vector-bug.cc 
test.cc:10:11: error: value of type '__attribute__((__vector_size__(4 *
sizeof(int)))) int' (vector of 4 'int' values) is not contextually convertible
to 'bool'
  vec r = a < b ? a : b;
          ^~~~~
1 error generated.

bitmac-mini:tmp abique$ clang++ --version
Apple clang version 11.0.3 (clang-1103.0.32.62)
Target: x86_64-apple-darwin19.6.0
Thread model: posix
InstalledDir:
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin


This works windows and linux.

Regards,
Alexandre
