Summary: Wrong code with -mcpu=8540 -mfloat-gprs=double -mspe
-Os on PowerPC
Product: gcc
Version: 4.5.2
Status: UNCONFIRMED
Severity: normal
Priority: P3

Assembler code.
In the attached assembler file:
Line 371: Save of non-volatile registers via stmw 25,28(1)
Line 454: Restore of non-volatile registers via b _rest64gpr_25_x
This procedure is completely wrong, e.g. _rest64gpr_25_x loads the link
register from a wrong stack position with an arbitrary value.
