83728effa9 Fix C++ exception handling. GCC was using the older BSD DBX register numbers 
rather than the ELF ABI/SVR4 ones in its DWARF unwinding.

d08a3fc2bc When I decided to use a stock dbxout.c rather than merge the rev 1.2 change 
(put the function stabs in traditional order on a.out, or gdb doesn't see
function local variables), I failed to remove the related knobs here.

Effectively were overrode the ELF-wide definition in elfos.h w/o providing
new infrastructure.  This is what caused GDB to fail to debug applications
compiled and linked with -stabs.  This is because GCC was unconditionally
inserts .stabs instruction for functions after the function body.  GDB was
getting confused because what it thinks is function beginning address is
actually function ending address.

4396d0e99f cc -O0 and -O1 didn't do the easy optimization of alignment for space. 
Instead it attempted to do the easy optimization of alignment for time,
which should be to 1-byte alignment on i386's.

670fd7ad58 Implement "-mno-align-long-strings" which prevents pessimization of strings 
for space.  -Os could do this, but it was easy to hack an MD version.
This saves a whole 32 bytes in boot2, so I think it is worth using it.
(keep how much worse gcc 3.2 will compile boot2...)

ec9ec8af6a Gcc 3.1 (-O) now generates broken inline code for memset in some cases. 
This broke newfs (newfs left some garbage in a bitmap).

The ASM for:

	#include <string.h>
	int x, foo[100];
	main()
	{
		memset(&foo[0], 0, x);
	}

is (at least if you have fixed function alignment):

	.file	"z.c"
	.text
	.p2align 2,,3
.globl main
	.type	main,@function
main:
	pushl	%ebp
	movl	%esp, %ebp
	pushl	%edi
	pushl	%eax
	movl	x, %ecx
	xorl	%eax, %eax
	shrl	$2, %ecx
	movl	$foo, %edi
	cld
	rep
	stosl
	andl	$-16, %esp
				<-- the lower bits of `len' should be loaded
				    near here
	testl	$2, %edi	<-- this seems to be meant to test the 2^1
				    bit in `len' (not alignment of the pointer
				    like it actually does).  %edi is the wrong
				    register for holding the bits, since it is
				    still needed for the pointer.
	je	.L2
	stosw
.L2:
	testl	$1, %edi	<-- similarly for the 2^0 bit.
	je	.L3
	stosb
.L3:
	movl	-4(%ebp), %edi
	leave
	ret
.Lfe1:
	.size	main,.Lfe1-main
	.comm	foo,400,32
	.comm	x,4,4
	.ident	"GCC: (GNU) 3.1 [FreeBSD] 20020509 (prerelease)"

This seems to only result in (len % 3) bytes not being cleared, since gcc
doesn't seem to use the builtin memset unless it knows that the pointer is
aligned.  If %edi could be misaligned, then too many bytes would be set.

79a702e6f3 The special checks for %b and %D in rev 1.1 were done before skipping over 
any characters between the % and the [bD], so only plain %b and %B worked.
This may un-1/2ass our -fformat-extensions support.

35abacef2a MD_EXEC_PREFIX doesn't work for the cross-arch compiler. 
The change also makes the `cc -print-search-dirs' output
sane (the pre-3.1 way) in the non-cross case.
