4a0f4fc5b5 Turn off the "-O2 flag TRIGGERS KNOWN OPTIMIZER BUGS" warning. 
From current testsuite results, the optimizer bugs don't appear to exist
anymore.  RTH@cygnus.com did a lot of work on the Alpha ELF code generator
for GCC 3.2[.0].  A recent FreeBSD/AXP GCC bootstrap is at
http://gcc.gnu.org/ml/gcc-testresults/2002-09/msg00604.html
In this bootstraps, all gcc libraries are built with -O2 and c-torture
gives -O2 a real workout.  None of the remaining failures have anything
to do with -O2 optimizer bugs.

77b0cabe7f Try to detect support for the `long long' type so that ANSI-C[89] clean 
code will know not to try to use `long long'.
Unfortunately the GCC spec parser will not allow us to properly detect the
"iso9899:1990" and "iso9899:199409" forms of the acceptable -std= arguments,
because of the ':' in the -std argument.  :-(  I have left them in the spec
as a place holder in hopes someone knows a way to make the detection of
them work.

599a83dfc4 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.

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.

9e7f705ccb MFC: gcc.295/config/alpha/freebsd.h revision 1.12: 
Remove our definition for FUNCTION_PROFILER as it is wrong.

Note that "jsr $28,_mcount" is a macro for
	ldq $27, _mcount($29)           !literal!1
	jsr $28, ($27), _mcount         !lituse_jsr!1

1. The call to _mcount is added by alpha_expand_prologue after we load the gp.
Our _mcount uses $27 for the incoming address, unlike OSF/1 and Linux,
which use $28.  This probably doesn't matter since we probably don't use $27
within _mcount itself.
2. You can't use this insn with _mcount because it uses the PLT, which clobbers
the return address in $28.  Note that the prologue_mcount pattern carefully
avoids adding the lituse_jsr relocation so that we call through the GOT
directly.

d40943f1a4 Re-initialize gp after a jsr. 
When rtld runs the .fini section in a shared lib (C++), the code in
question from .../contrib/gdb/config/alpha/crtbegin.asm first calls
__do_globals_dtors_aux and then __do_frame_takedown.  Unfortunately, the
value of gp after a jsr is undefined and in this case had changed from before
the call, probably as a result of calling code in some other shared library.
The normal calling convention for alpha is to re-initialize gp using
'ldgp gp,0(ra)' after a jsr instruction but in this case no such
re-initialization is done. This leads to a bogus value being read for the
address of __do_frame_takedown and a quick segfault.

cd3f3aab8e Add the `WANT_FORCE_OPTIMIZATION_DOWNGRADE' knob. If set to an integer

made with "WANT_FORCE_OPTIMIZATION_DOWNGRADE=1" is a good setting for the

0983569eda Make it easy for people to use define DWARF2 exceptions unwinding. 
If "WANT_DWARF2_UNWIND" you get it.  Note that this is a different C++ ABI
than the FreeBSD default.  So you will need to recompile all your C++ apps
that uses exceptions if you turn this on.  I am adding it here for Yahoo!'s
use and for those that want to be early adopters to what I will make as the
default with the GCC 3.0 import.
