+Subject: cmd/go, cmd/cgo: pass -mfp32 and -mhard/soft-float to MIPS GCC
+
+For mips32 currently, we are using FP32, while the gcc may be FPXX,
+which may generate .MIPS.abiflags and .gnu.attributes section with
+value as FPXX. So the kernel will treat the exe as FPXX, and may
+choose to use FR=1 FPU mode for it.
+Currently, in Go, we use 2 lwc1 to load both half of a double value
+to a pair of even-odd FPR. This behavior can only work with FR=0 mode.
+
+In FR=1 mode, all of 32 FPR are 64bit. If we lwc1 the high-half of a double
+value to an odd FPR, and try to use the previous even FPR to compute, the
+real high-half of even FPR will be unpredicatable.
+We set -mfp32 to force the gcc generate FP32 code and section value.
+
+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
+
+When GOMIPS/GOMIPS64 is set as softfloat, we should also pass
+ -msoft-float to gcc.
+
+Here we also add -mno-odd-spreg option, since Loongson's CPU cannot use
+odd-number FR in FR=0 mode.
+
+Fixes #39435
