Summary: clang does not know FP registers gcc does
Product: clang
Version: trunk
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P
Component: Frontend
AssignedTo: [email protected]

In RTEMS, we use some inline assembly to assist in FPU context switches. clang
has trouble with the two attached test cases. I think we use two registers
clang does not know about yet. This can likely be reduced but I thought it
better to stick with two real examples so when this is addressed, it is more
likely to let this code in RTEMS compile.
