Subject: [PATCH] target-ppc: fix bit extraction for FPBF and FPL
|
|
|
|
Bit extraction for the FP BF and L field of the MTFSFI and MTFSF
|
|
instructions is wrong and doesn't match the reference manual (which
|
|
explain the bit number in big endian format). It has been broken in
|
|
commit 7d08d85645def18eac2a9d672c1868a35e0bcf79.
|
|
|
|
This patch fixes this, which in turn fixes the problem reported by
|
|
Khem Raj about the floor() function of libm.
