Hello, I'm updating the setjmp/longjmp functions on ARM to reduce the diff to NetBSD and to store the VFP registers when they are available. As part of this I will be removeing support for storing the FPA (floating point accelerator) registers. Does anyone have any objections to this? The first patch is at [1]. It updates out code to remove the FPA support but doesn't yet add the VFP as that will require other libc changes. (If you don't know what the FPA is this patch probably doesn't affect you, it was an old floating-point device in only a few chips. Modern CPUs use a different piece of hardware for floating point operations.) Andrew [1] http://people.freebsd.org/~andrew/arm_setjmp.diff
