There is a bug in macro assembler in vinserti128 special handling for platforms like KNL that do not support AVX512VL.
The following:
void vinserti128(XMMRegister dst, XMMRegister nds, XMMRegister src, uint8_t imm8) {
if (UseAVX > 2 && VM_Version::supports_avx512novl()) {
Assembler::vinserti32x4(dst, dst, src, imm8);
}
...
}
Should have been:
void vinserti128(XMMRegister dst, XMMRegister nds, XMMRegister src, uint8_t imm8) {
if (UseAVX > 2 && VM_Version::supports_avx512novl()) {
Assembler::vinserti32x4(dst, nds, src, imm8);
}
...
}
The following:
void vinserti128(XMMRegister dst, XMMRegister nds, XMMRegister src, uint8_t imm8) {
if (UseAVX > 2 && VM_Version::supports_avx512novl()) {
Assembler::vinserti32x4(dst, dst, src, imm8);
}
...
}
Should have been:
void vinserti128(XMMRegister dst, XMMRegister nds, XMMRegister src, uint8_t imm8) {
if (UseAVX > 2 && VM_Version::supports_avx512novl()) {
Assembler::vinserti32x4(dst, nds, src, imm8);
}
...
}
