28b73f7a82 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...)

616a2ae30e Fix excessive alignment for the aout case, and unbreak genassym for that case. 
Our aout linker has alignment hacks and doesn't need gcc to do anything special.

6e1cb4b9ca The brokenness in ix86_expand_clrstr is quite visible when you 
compare the function with ix86_expand_movstr.

d047bea9fd 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.

c63b7df4ec 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.
