In at least one case found in our testfarm, the compiler runs into an
ICE (Internal Compiler Error) compiling the new AVX code. The error it
reported was:
fatal error: error in backend: Cannot select: 0x7fbf1aa42210: f64 = sint_to_fp 0x7fbf1aa88a10 [ORD=1936] [ID=37]
0x7fbf1aa88a10: i32,ch = CopyFromReg 0x7fbf19538768, 0x7fbf1a9f2610 [ORD=1936] [ID=27]
0x7fbf1a9f2610: i32 = Register %vreg38 [ORD=1936] [ID=9]
As is the nature of ICEs, juggling the code around will probably make
it pass. But since I have plenty more AVX changes pending, which make
the code even more complex, it's also very likely that this issue will
happen in other places. For that reason, I choose to blacklist the
compiler instead.
