Agreed. For soft-float, the value would be a a GPR pair versus a FPR pair (for
-m64). It's a little tricker for -m32 -msoft-float compiles, since a 128-bit
long double would live in 4 32-bit GPRs, so more regs than it takes to hold
them in FPRs. Not much of a complication, but just needs to be tested on
32-bit to ensure it works as expected.
