Bug ID: 15546
Summary: Possible unsafe maths bug in NEON VMUL.f32
Product: libraries
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: Backend: ARM
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Classification: Unclassified
As described in bug #15545, NEON's SPFP VMUL is not IEEE 754 compliant and that
is failing a test (TSVC).
But NEON VMUL.f32 is faster than VFP's version, so in A8, A5 and Swift, it's
enabled by default.
Question is: do we really want this enabled by default when safe-math is on?
