Allow the unwind functions int libgcc_s to interact correctly with libthr.

_Unwind_ForcedUnwind in libgcc_s takes as one of it's parameters a stop
function to tell it when to stop unwinding. One of the stop function's
parameters is a _Unwind_Exception_Class. On most architectures this is an
int64_t, however on ARM EABI the gcc developers have made this a char array
with 8 items. While both of these take the same space they are passed into
the stop function differently, an int64_t is passed in in registers r2 and
r3, while the char[8] is passed in as a pointer to the first item in
register r2.

Because libthr expects the value to be an int64_t we would get incorrect
results when it passes a function that take an int64_t but libgcc passes in
a pointer to a char array including crashing.

The fix is to update libgcc_s to make it pass an int64_t to the stop
function and to libstdc++ as it expects _Unwind_Exception_Class to be an
array.

Add compiler support for the ARM EABI.

ARM EABI support is disabled by default and can be enabled by setting
WITH_ARM_EABI when building, however only the kernel-toolchain target will
work with this flag until the rest of the support is added.

Switch the default CPU to an arm9. This removes compiler support for the
unsupported 26-bit addressing mode. This change is required for moving to
the ARM EABI.

Add an ugly hack to libgcc's unwind code, to make it behave properly at
runtime on amd64, when it is compiled by clang. Some versions of clang
don't save and restore all callee registers, if a __builtin_eh_return()
intrinsic is used in a function. This is particularly bad on amd64.

Until the problem gets fixed by upstream, use an asm statement to force
clang to assume the registers in question are clobbered, when invoking
__builtin_eh_return(), so it will emit code to save and restore them.

This should fix the crashes reported on -current with some C++ programs,
particularly those that throw exceptions over multiple function
boundaries.

gcc: avoid generating negative values to DW_AT_byte_size.

There is a bug in gcc (GCC/35998) where dwarf reports
sizes of unsigned -1 (0xffffffff).

On NetBSD this generated a faulty CTF entry which then
caused a segfault in ctfmerge. The issue was worked
around in NetBSD's Dtrace but since the issue originated
in gcc, it seems reasonable to fix it here.

Upstream gcc has been slow to react to this issue and
the author that submitted the patch is not interested
in licensing the change to us, so I did an independent
workaround for the issue.

Don't define CTORS_SECTION_ASM_OP and DTORS_SECTION_ASM_OP on arm when
built with clang. When these are defined the lists are defined similar to:

asm(".section .ctors");
STATIC func_ptr __CTOR_LIST__[1] = { (func_ptr) (-1) };
asm(".section .dtors");
STATIC func_ptr __DTOR_LIST__[1] = { (func_ptr) (-1) };

The problem is clang will move the two arrays out of the .ctors and .dtors
sections causing these sections to contain a single null address. By not
defining these macros we use the version of the code that places the arrays
is their sections by using __attribute__((section(".ctors"))) and similar
for .dtors.

* GCC to predefine __FreeBSD_ARCH_armv6__
* gas to default to ARM_ARCH_V6K

etire the cpumask_t type and replace it with cpuset_t usage.

This is intended to fix the bug where cpu mask objects are
capped to 32. MAXCPU, then, can now arbitrarely bumped to whatever
value. Anyway, as long as several structures in the kernel are
statically allocated and sized as MAXCPU, it is suggested to keep it
as low as possible for the time being.

Technical notes on this commit itself:
- More functions to handle with cpuset_t objects are introduced.
The most notable are cpusetobj_ffs() (which calculates a ffs(3)
for a cpuset_t object), cpusetobj_strprint() (which prepares a string
representing a cpuset_t object) and cpusetobj_strscan() (which
creates a valid cpuset_t starting from a string representation).
- pc_cpumask and pc_other_cpus are target to be removed soon.
With the moving from cpumask_t to cpuset_t they are now inefficient
and not really useful. Anyway, for the time being, please note that
access to pcpu datas is protected by sched_pin() in order to avoid
migrating the CPU while reading more than one (possible) word
- Please note that size of cpuset_t objects may differ between kernel
and userland. While this is not directly related to the patch itself,
it is good to understand that concept and possibly use the patch
as a reference on how to deal with cpuset_t objects in userland, when
accessing kernland members.
- KTR_CPUMASK is changed and now is represented through a string, to be
set as the example reported in NOTES.

Please additively note that no MAXCPU is bumped in this patch, but
private testing has been done until to MAXCPU=128 on a real 8x8x2(htt)
machine (amd64).

Please note that the FreeBSD version is not yet bumped because of
the upcoming pcpu changes. However, note that this patch is not
targeted for MFC.

Due to this, rs6000_elf_end_indicate_exec_stack() only emit the note for
32 bit target. I decided not to change FreeBSD ABI and patch

Now that the fix for gcc PR 20218 is applied, and hidden attributes

Teach our toolchain how to generate 64-bit PowerPC binaries. This fixes
a variety of bugs in binutils related to handling of 64-bit PPC ELF,
provides a GCC configuration for 64-bit PowerPC on FreeBSD, and
associated build systems tweaks.

Obtained from: projects/ppc64

Add/improve mips64r2, Octeon, n32 and n64 support in the toolchain.

o) Add TARGET_ABI to the MIPS toolchain build process. This sets the default
ABI to one of o32, n32 or n64. If it is not set, o32 is assumed as that is
the current default.
o) Set the default GCC cpu type to any specified TARGET_CPUTYPE. This is
necessary to have a working "cc" if e.g. mips64 is specified, as binutils
will refuse to link objects using different ISAs in some cases.
o) Add support for n32 and n64 ABIs to binutils and GCC.
o) Add additional required libgcc2 stubs for n32 and n64.
o) Add support for the "mips64r2" architecture to GCC. Add the "octeon"
o) When static linking, wrap default libraries in --start-group and
--end-group. This is required for static linking to work on n64 with the
interdependencies between libraries there. This is what other OSes that
support n64 seem to do, as well.
o) Fix our GCC spec to define __mips64 for 64-bit targets, not __mips64__, the
former being what libgcc, etc., check and the latter seemingly being a
misspelling of a hand merge from a Linux spec.
o) When no TARGET_CPUTYPE is specified at build time, make GCC take the default
ISA from the ABI. Our old defaults were too liberal and assumed that 64-bit
ABIs should default to the MIPS64 ISA and that 32-bit ABIs should default to
the MIPS32 ISA, when we are supporting or will support some systems based on
earlier 32-bit and 64-bit ISAs, most notably MIPS-III.
o) Merge a new opcode file (and support code) from a later version of binutils
and add flags and code necessary to support Octeon-specific instructions.
This should also make merging opcodes for other modern architectures easier.

Merge an important change that I mistakenly left out when merging C99
inline function support. This should fix instances where gcc
spuriously reports the following error:

error: nested function 'foo' declared but never defined

Make gcc use C99 inline semantics in c99 and gnu99 mode. This was the
original intent, but the functionality wasn't implemented until after
gcc 4.2 was released. However, if you compiled a program that would
behave differently before and after this change, gcc 4.2 would have
warned you; hence, everything currently in the base system is
unaffected by this change. This patch also adds additional warnings
about certain inline function-related bogosity, e.g., using a
static non-const local variable in an inline function.

These changes were merged from a snapshot of gcc mainline from March
2007, prior to the GPLv3 switch. I then ran the regression test suite
from a more recent gcc snapshot and fixed the important bugs it found.
I also squelched the following warning unless -pedantic is specified:

foo is static but used in inline function bar which is not static

This is consistent with LLVM's behavior, but not consistent with gcc 4.3.

Fixed -mprofiler-epilogue. The garbage collector apparently doesn't

it collected the static variable for mexitcount_libfunc, gcc aborted

This quick fix is to reinitialize the variable on every use and depend
on garbage collection recovering the small amount of memory wasted by
this, and not worry by the small amount of time wasted by this. It
would be better to initialize the variable together with most of the
other libfuncs in optabs.c and depend on whatever magic is there to
prevent its collection, but we initialize it here to avoid taking at

Bump __FreeBSD_cc_version for (1) 5.1 (post-mortem) (2) -pthread changes.

Remove the -pthread option (in FreeBSD versions 500016 and greater) as
threatened over 2 years ago.

Why? -pthread was a hack to prevent linking to both libc and libc_r
and became unecessary when libc_r became free of libc. Now that we
have multiple thread libraries from which to choose, it is more confusing
because you can't link to more than one threads library at a time.
Things like autoconf and libtool sometimes detect -pthread and
also -lc_r, and in conjunction with ports usage of ${PTHREAD_LIBS},
really wacky things ensue when PTHREAD_LIBS is set to another
threads library. This might not be so bad if the build broke
when this happens, but it doesn't and you don't know it until
funny things happen when you run the application (or use an
affected library).

main() changed its argv declaration, so follow suit in some FBSD added code.

Fix a bug in GCC which effectively prevents DEFAULT_PCC_STRUCT_RETURN from
having any effect. This restores a calling convention traditionally used
by FreeBSD/i386 and which is expected by a number of assembly sources
in libc.

Fix C++ exception handling. GCC was using the older BSD DBX register numbers

Submitted by: Alexander Kabaev <ak03@gte.com>

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.

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

.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.

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.

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.

... /usr/lib/libgcc.a -lc_r -lc /usr/lib/libgcc.a ...

It would be possible to make them identical, but that doesn't fit
as nicely into GCC's way of doing things. I don't think the ordering
change will make any difference in practice.

Do not use DWARF2 unwinding mechanisms for C++ exceptions on all of our
platforms.

ASM_DECLARE_OBJECT_NAME and ASM_FINISH_DECLARE_OBJECT are ELF MI routines
to generate the special .type and .size directives which are used to set
the corresponding fields of the linker symbol table entries in the ELF
object file. As such they are not i386-specific and thus belong in our
MI header. Otherwise on the Alpha we don't properly give the type and
size of dynamic symbols. Bintuil versions past 2.9.1 warn of this and
w/o this change, `ld' generates a lot of warnings during a `make world'.

Clarify that the "yields only last 2 digits of year in some locales" warning
does not apply to BSD.

Fix our -mprofiler-epilogue code.

"The problem is that egcs/gcc-2.95's reorganisation of the prologue and
epilogue code to use rtl instead of output_asm_insn() completely broke our
hooks. rtl is emitted in a different order, only after optimisation, while
output_asm_insn() is emitted immediately. rtl is presumably used so that
the prologue and epilogue can be optimised.

I couldn't find any good examples to copy. gcc's own
FUNCTION_BLOCK_PROFILER still uses output_asm_insn() and seems to be
completely broken. One of the XXX comments points to this.

IIRC, the hacks here basically arrange to emit magic label names; then when
the magic names are output, they are transformed into prologue and epilogue
code."

This should get us the same functionality we had with GCC 2.7.2.1.

* Support for our dual ELF/a.out building ability
* Our custom ASM_* definitions
* Our custom debugger and profiling related definitions
* Our custom STARTFILE/ENDFILE specs

* The stock EGCS 1.1.2 freebsd-elf.h file depended on
egcs-1.1.2/gcc/config/linux.h, which included "svr4.h". We will
include "svr4.h" via our "tm.h" definition. So add the few bits
from "linux.h" we actually needed.

* Using our current crtbegin.o/crtend.o we cannot support the DWARF2
unwinding mechanisms. In the future we will switch to the
non-sjlj-exceptions type exception machanism. However the `make world'
bootstrap problems with the EGCS crtstuff.c must be overcome first.

* Our a.out gas doesn't "know" to use NOP's for aligns while in the text
section. Thus the a.out alignment generation needed tweaking from
what we did with GCC 2.7.2. [from BDE]

* The definition of SUPPORTS_ONE_ONLY prevents the compiler from trying
to use "linkonce" sections for a.out. The definition of
NO_DBX_FUNCTION_END we had causes it to avoid .stabs symbols that the
assembler cannot handle for a.out. [from JDP]

* The previous "EXCEPTION_SECTION_FUNCTION" is the wrong name for EGCS.
It also needed tweaking for EGCS. [from JDP]

Don't exclude directories that the linker is "known" to search (/lib

/lib and to only search /usr/lib in the elf case. Not passing the
paths causes at best causes confusing differences for cross compiling.

Correct vfork()/exit() to vfork()/_exit().

Also return "1" rather than "-1". According to bde: -1 is unrepresentable.
Exit statuses must be >= 0 and <= 255, at least if chars are 8 bits and
shorts are 16 bits. This seems to only be documented indirectly in exit.2
by referring to wait.2. WEXITSTATUS() throws away all except the low 8 bits
of the status returned by _exit(), and the kernel actually only stores 8
bits of it (if chars are 8 bits, etc.), so wait() can't return any more bits.

Don't accept %q length specifiers in the kernel (more precisely,
if compiling with -fformat-extensions). Gcc's format checker never
actually supported %q length specifiers. It treats %q as an alias
for %ll, which is correct if quad_t is long long (e.g., on i386's)
and broken otherwise (e.g., on alphas).

quad_t's currently should be printed in the same way that they
already need to be printed to avoid compiler warnings on all
supported systems: cast them to a standard type that is at least
as large (long or long long) and use the length specifier for that
(%l or %ll). This is problematic since long long isn't standard
yet. C9x's intmax_t should be implemented soon.

Don't accept %L length specifiers in the kernel either. The only
legitimate ones are for long doubles, but the kernel doesn't even
support plain doubles. (gcc bogusly accepts %Ld as an alias for
%lld, and it sometimes prints "q" in error messages about "ll" and
"L" length specifiers, becauses it represents all these specifiers
as 'q'.)

Fixed kernel format checking:
- plain %r and %z were disallowed. The hard NULs in the warnings were
hopefully caused by disallowing of plain formats being nonsense.
- new formats for shortening to a byte were allowed, but even the libc
printf doesn't support them.
- old %hr and %hz formats were allowed, but the kernel printf doesn't
support them. The kernel doesn't support %hd either, but this is
harder to fix.
