<pre>While compiling Boost.SIMD unti test on a XOP machine (see spec here
<a href="https://gist.github.com/jfalcou/7003868d2e71eba5c03a">https://gist.github.com/jfalcou/7003868d2e71eba5c03a</a>), clang-3.5 from Debian
repository ICE with the following message :
fatal error: error in backend: Cannot select: 0x8826330: v4i32 = BUILD_VECTOR
0x9bbb9d0, 0x9bbb9d0, 0x9bbb9d0, 0x9bbb9d0 [ORD=36] [ID=34]
0x9bbb9d0: i32 = Constant<1> [ID=29]
0x9bbb9d0: i32 = Constant<1> [ID=29]
0x9bbb9d0: i32 = Constant<1> [ID=29]
0x9bbb9d0: i32 = Constant<1> [ID=29]
In function: _Z24test_main_sqr_signed_intv
The boost::simd::sqr function just performs the equivalent of multiplying a
SIMD vector with itself.
The preprocessed output + .sh from clang output is 18Mb and is available here :
