System: NetBSD buzzard.buzzard.freeserve.co.uk 1.5I NetBSD 1.5I (BUZZARD) #216: Sun Nov 19 21:24:48 GMT 2000 rearnsha@buzzard.buzzard.freeserve.co.uk:/usr/src/sys/arch/arm32/compile/BUZZARD arm32


>Description:
	a code sequence of the form

	if (something_simple)
		foo = const1;
	else
		foo = MIN (something_else_simple, const1)

	is miscompiled on the ARM due to a bug in the in-tree compiler
	
>How-To-Repeat:
	Try to compile the latests gcc snapshots from gcc.gnu.org at -O2 with
	the current arm32 compiler.
	
>Fix:

	The following patch is a back-port from the egcs-2.95 release of the
	compiler.
