cmd/link,debug/elf: mips32, add .gnu.attributes and .MIPS.abiflags sections MIPS32 uses .gnu.attributes and .MIPS.abiflags sections to mark FP ABI the object is using, and the kernel will set the correct FP mode for it. Currrently Go doesn't generate these 2 sections. If we link object without these 2 sections togather FPXX objects, the result will be FPXX, which is wrong: FP32 + FPXX -> FP32 FPXX + FP64 -> FP64 FP32 + FP64 -> reject These 2 sections is also needed to support FPXX and FP64 in future. More details about FP32/FPXX/FP64 are explained in: https://web.archive.org/web/20180828210612/https://dmz-portal.mips.com/wiki/MIPS_O32_ABI_-_FR0_and_FR1_Interlinking Fixes #39677 Change-Id: Ia34e7461dee38a4f575dd8ace609988744512ac1 Reviewed-on: https://go-review.googlesource.com/c/go/+/239217 Run-TryBot: Cherry Zhang <cherryyz@google.com> Reviewed-by: Cherry Zhang <cherryyz@google.com> TryBot-Result: Go Bot <gobot@golang.org> Trust: Meng Zhuo <mzh@golangcn.org>
