Keith Randall ea106cc07a cmd/compile: prevent 387+float32+pie from clobbering registers The 387 port needs to load a floating-point control word from a global location to implement float32 arithmetic. When compiling with -pie, loading that control word clobbers an integer register. If that register had something important in it, boom. Fix by using LEAL to materialize the address of the global location first. LEAL with -pie works because the destination register is used as the scratch register. 387 support is about to go away (#40255), so this will need to be backported to have any effect. No test. I have one, but it requires building with -pie, which requires cgo. Our testing infrastructure doesn't make that easy. Not worth it for a port which is about to vanish.
