[Qemu-devel] [PATCH v2] target-ppc: fix nego and subf*o instructions

2013-03-31 Thread Aurelien Jarno
The overflow computation of nego and subf*o instructions has been broken in commit ffe30937. Contrary to other targets, the instruction is subtract from an not subtract on PowerPC. This patch fixes the issue by using the correct argument in the xor computation. Thanks to Peter Maydell for the hint
