nested function question

[Aurelien Buhrig]

Hi,

The gcc.c-torture/execute/nestfunc-3.c test fails on a private target. I
suspect this is because the STATIC_CHAIN_REGNUM, which is not a call
used register, is used by the caller function (main), modified by the
trampoline, but not restored upon nested function return.

Should the STATIC_CHAIN_REGNUM be defined so that
CALL_USED_REGISTERS[STATIC_CHAIN_REGNUM] == 0?


Thanks,
Aurélien
