powerpc: Add VSX context save/restore, ptrace and signal support

2008-07-01T01:28:50Z

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. Signed-off-by: Michael Neuling Signed-off-by: Paul Mackerras

Revert "[POWERPC] Add compat handler for PTRACE_GETSIGINFO"

2008-04-24T04:05:15Z

This reverts commit e4cc58944c1e2ce41e3079d4eb60c95e7ce04b2b, as requested by Roland McGrath, because compat_ptrace_request (added in commit e16b27816462de700f9508d86954410c41105dc2, "ptrace: compat_ptrace_request siginfo") now handles this case. Signed-off-by: Paul Mackerras

[POWERPC] Add compat handler for PTRACE_GETSIGINFO

2008-04-20T03:03:36Z

Current versions of gdb require a working implementation of PTRACE_GETSIGINFO for proper watchpoint support. Since struct siginfo contains pointers it must be converted when passed to a 32-bit debugger. Signed-off-by: Andreas Schwab Signed-off-by: Paul Mackerras
