Summary: x86-64 doesn't save nonvolatile XMM6-XMM15 registers
Product: new-bugs
Version: unspecified
Platform: PC
OS/Version: Windows XP
Status: NEW
Severity: normal
Priority: P2
Component: new bugs
AssignedTo: [EMAIL PROTECTED]
ReportedBy: [EMAIL PROTECTED]
CC: [email protected]
The x86-64 ABI specifies that XMM6 to XMM15 are non-volatile, and should be
preserved by the callee as needed. It appears that LLVM currently doesn't do
this, causing unpredictable behavior with floating-point calculations.
