Bug ID: 83315
Summary: PowerPC xmmintrin.h emulation for _mm_{min,max}_ps not
semantically equivalent
Product: gcc
Version: 8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: dje at gcc dot gnu.org
Target Milestone: ---
PowerPC port xmmintrin.h _mm_min_ps invokes Power vec_min instrinsic and
_mm_max_ps invokes Power vec_max instrinsic. vec_min corresponds to the
xsminsp instruction and vec_max corresponds to the xsmaxsp instruction. The
Power instructions implement different semantics for NaN than the Intel
equivalents. The Power ISA 3.0 (Power9) xsmincsp and xsmaxcsp instructions
correspond to the Intel semantics.
