Bug ID: 22347
Summary: ICE when generating XOP code for integer
Product: clang
Version: 3.5
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: -New Bugs

Classification: Unclassified
While compiling Boost.SIMD unti test on a XOP machine (see spec here
https://gist.github.com/jfalcou/7003868d2e71eba5c03a), 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 :
