Maksim Masalski 0343118abb thread: set mxcsr bit 6 DAZ to zero to disable denormals-are-zeros ... Currently we are using mxcsr register with the bit 6 DAZ enabled. When the denormals-are-zeros flag is set, the processor converts all denormal source operands to a zero with the sign of the original operand before performing any computations on them. It causes bugs in the SIMD XMM registers computation like #38646 I suggest to disable Denormals-Are-Zeros flag and mask division-by-zero exception. Set value to the default 1F80H according to the Intel(R) 64 and IA-32 Architectures Software Developer's Manual. Fix will let all x86 boards perform SIMD computation using XMM registers in the correct way. Fixes #38646 Signed-off-by: Maksim Masalski <maksim.masalski@intel.com>		2021-09-22 08:34:18 -04:00
