Import of unmodified (but trimmed) gcc-2.7.2. The bigger parts of the

non-i386, non-unix, and generatable files have been trimmed, but can easily
be added in later if needed.

gcc-2.7.2.1 will follow shortly, it's a very small delta to this and it's
handy to have both available for reference for such little cost.

The freebsd-specific changes will then be committed, and once the dust has
settled, the bmakefiles will be committed to use this code.

+ *
+ * 	Varargs for PYR/GNU CC
+ *
+ * WARNING -- WARNING -- DANGER
+ *
+ * The code in this file implements varargs for gcc on a pyr in
+ * a way that is compatible with code compiled by the Pyramid Technology
+ * C compiler.
+ * As such, it depends strongly on the Pyramid conventions for
+ * parameter passing.ct and independent implementation. 
+ * These (somewhat bizarre) parameter-passing conventions are described
+ * in the ``OSx Operating System Porting Guide''.
+ * 
+ * A quick summary is useful:
+ * 12 of the 48 register-windowed regs available for
+ * parameter passing.  Parameters of a function call that are eligible
+ * to be passed in registers are assigned registers from TR0/PR0 onwards;
+ * all other arguments are passed on the stack.
+ * Structure and union parameters are *never* passed in registers,
+ * even if they are small enough to fit.  They are always passed on
+ * the stack.
+ *
+ * Double-sized parameters cannot be passed in TR11, because
+ * TR12 is not used for passing parameters.  If, in the absence of this
+ * rule, a double-sized param would have been passed in TR11,
+ * that parameter is passed on the stack and no parameters are
+ * passed in TR11.
+ * 
+ * It is only known to work for passing 32-bit integer quantities
+ * (ie chars, shorts, ints/enums, longs), doubles, or pointers. 
+ * Passing structures on a Pyramid via varargs is a loser.
+ * Passing an object larger than 8 bytes on a pyramid via varargs may
+ * also be a loser.
