On x86 targets that support f16c (ivybridge in my case), dev-libs/imath tries to use the intrinsics _cvtss_sh/_cvtsh_ss because __F16C__ is defined, but only includes the intrinsics header when __x86_64__ is defined. Reproducible: Always Steps to Reproduce: 1. Compile dev-libs/imath-3.1.4-r3 on x86 arch with f16c support Actual Results: Compilation error: '_cvtsh_ss' was not declared in this scope (see emerge.log) Expected Results: Successful compilation.
