linux.git/arch/mips/include/uapi/asm/sigcontext.h, branch v3.15 Linux kernel source tree MIPS: Save/restore MSA context around signals 2014-03-26T22:09:11+00:00 Paul Burton paul.burton@imgtec.com 2014-02-13T11:27:42+00:00 eec43a224cf198c7e3538fca16f689e4d17d4471 This patch extends sigcontext in order to hold the most significant 64 bits of each vector register in addition to the MSA control & status register. The least significant 64 bits are already saved as the scalar FP context. This makes things a little awkward since the least & most significant 64 bits of each vector register are not contiguous in memory. Thus the copy_u & insert instructions are used to transfer the values of the most significant 64 bits via GP registers.
