Summary: FLT_EVAL_METHOD sometimes wrong for Intel FPUs
Product: new-bugs
Version: 2.8
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P
Component: new bugs

FLT_EVAL_METHOD needs to depend upon which FPU code is being generated for.
If the sse2 FPU is being used for float, then FLT_EVAL_METHOD should be 0.
If the x87 FPU is being use for float, then FLT_EVAL_METHOD should be 2.
I forced the use of x87 on a Pentium 4 with -mno-see
Is there some macro symbol defined by the compiler that the user's program
can check to see which FPU is being used?
