09ab966d37 Convert the bison-output-checked-into-cvs makefile handling stuff to work 
like the flex stuff, which actually works when people do cvs updates and
get conflicts in the updated checked in file.

e75debf037 Sparc actually *DOES* have a directive for emitting zeros. In fact, it requires 
it, because this:

.bss
X:
.byte 0

results in the assembler warning: "initialization in bss segment".  Annoying.

8e7f48c96d Fix SingleSource/Regression/C/2004-08-12-InlinerAndAllocas.c on Sparc. 
The ABI specifies that there is a register save area at the bottom of the
stack, which means the actual used pointer needs to be an offset from
the subtracted value.

bdcf945194 HP aCC (and a bunch of other compilers, no doubt) don't share 
GCC's syntax for auto-dependency generation stuff. This should
be changed to be disabling dependency stuff unless GCC/ICC is
found.

4c6740419b previously, configure would die if GCC or ICC was not found. Now it'll 
go through, but we do want to know if we're using GCC/ICC since they
share certain funky command line options (for dependency generation
stuff)

99b81c856f Canonicalize inner loops before outer loops. Inner loop canonicalization 
can provide work for the outer loop to canonicalize.

This fixes a case that breaks unswitching.

277e76337e When splitting exit edges to canonicalize loops, make sure to put the new 
block in the appropriate loop nest.

Third time is the charm, right?

af26f481e9 If we have zero initialized data with external linkage, use .zerofill to 
emit it (instead of .space), saving a bit of space in the .o file.

For example:
int foo[100];
int bar[100] = {};

when compiled with C++ or -fno-common results in shrinkage from 1160 to 360
bytes of space.  The X86 backend can also do this on darwin.
