H A D | fpu.S | diff ce48b2100785e5ca629fb3aa8e3b50aca808f692 Tue Jun 24 23:07:18 CDT 2008 Michael Neuling <mikey@neuling.org> powerpc: Add VSX context save/restore, ptrace and signal support
This patch extends the floating point save and restore code to use the VSX load/stores when VSX is available. This will make FP context save/restore marginally slower on FP only code, when VSX is available, as it has to load/store 128bits rather than just 64bits.
Mixing FP, VMX and VSX code will get constant architected state.
The signals interface is extended to enable access to VSR 0-31 doubleword 1 after discussions with tool chain maintainers. Backward compatibility is maintained.
The ptrace interface is also extended to allow access to VSR 0-31 full registers.
