* libguile/struct.h (SCM_VTABLE_FLAG_VALIDATED): New flag, indicates
that the layout of a vtable has been validated. The other flags have
been renumbered.
* libguile/struct.c (scm_i_struct_inherit_vtable_magic): Set the
VALIDATED flag if everything goes through.
(scm_struct_vtable_p): If the struct should be a vtable but isn't
validated, throw an error.
(scm_make_vtable_vtable): Validate the incoming user_fields layout
bit. Set the VALIDATED flag.
(scm_c_make_structv): Add a comment about the case in which we delay
scm_i_struct_inherit_vtable_magic.
There is no guarantee of order of jit_function calls, so, it must
reset it for every function. This should correct possible issues in
OS/X, and will be required when i386 code is updated to use MMX/SSE*
registers, possibly as some kind of extended interface, and then,
would require 16 bytes aligned stack. This is already an issue if
calling C code that uses SSE, and currently requires "manually"
padding the stack by using jit_allocai.
The problems would also happen with 32 bit unsigned operands that would
happen to have the topmost bit set, so, now it only uses 32 bit immediates
when bit 31 is not set.
This patch correct all the issues found by the test cases alu_add.tst and
alu_sub.tst in http://code.google.com/p/exl/source/browse/trunk/check/lightning
The checks were moved from i386/asm.h to i386/asm-{32,64}.h, as well
as some macros from core-{32,64}.h. Now it checks if the value is in the
range of a valid register, and in the proper register class, what should
prevent the common mistake of calling a jit*r_x macro passing an immediate
as argument.
Now it pass lightning's make check in i386/x86_64, as well as all test
cases in http://code.google.com/p/exl/source/browse/trunk/check/lightning
when compiled with -D_ASM_SAFETY.
jit_bra_l had the logic reversed, and correcting that also corrected
jit_b{lt,le,eq,ge,gt,ne}i_l.
TESTQir and _ALUQir were not properly working with 64 bit immediates,
that require using a temporary register (JIT_REXTMP) as there are no
related opcodes for 64 bit immediates. This corrected jit_bm{s,c}i_l and
jit_bo{add,sub}i_l.
Now, the tests in
http://code.google.com/p/exl/source/browse/trunk/check/lightning/branch.tst
pass.
* libguile/deprecation.c (scm_c_issue_deprecation_warning):
* libguile/extensions.c (scm_c_register_extension, load_extension): Add
locks around global data structures.
* module/rnrs/arithmetic/fixnums.scm (fixnum-width): Make this return an
an exact integer instead of an inexact number.
* module/rnrs/base.scm (assertion-violation): Implement.
* module/rnrs/conditions.scm (simple-conditions): Allow also simple
conditions as argument.
* module/rnrs/enums.scm (define-enumeration): Properly construct empty
enumeration sets.

single expression.
* module/rnrs/records/syntactic.scm (define-record-type0): Expand into a
series of definitions only.
This reverts commit 6832604efa. Not only
does this fail on a fresh build due to a lack of "guile", but even if it
did have its Makefile fixed, it would take too long to run, because the
rest of Guile isn't compiled.
The right thing is to avoid invoking Guile until after at least psyntax
and boot-9 have been compiled.
This commit can be reinstated if we move doc snarfing to a phase that
happens after module/ is compiled.
This partially reverts commit 6e9f3c2676
(Tue May 3 2005).
* module/srfi/srfi-1.scm (break, break!): New procedures.
* srfi/srfi-1.c (scm_srfi1_break, scm_srfi1_break_x): Rewrite as
proxies to the corresponding Scheme procedures.
* test-suite/standalone/test-srfi-1.c (failure): New function.
(tests): Add `scm_srfi1_break' test. Use `failure'.
* libguile/guile-snarf-docs.in: Rewrite to incorporate all
three phases of snarfing: func-name check, cpp, tokenization.
Also, require/check new command-line syntax.
* libguile/Makefile.am (AM_V_FILTER): Delete var.
(AM_V_FILTER_, AM_V_FILTER_0): Likewise.
(.c.doc): Run ./guile-snarf-docs; use new command-line syntax.
The x86_64 correction to keep stack aligned in jit_finish* was only
correct for functions being called, but did not correctly handle alignment
of stack arguments.
* configure.ac (sitedir): Fix definition to point to the
version-specific sitedir.
* libguile/Makefile.am (libpath.h): Take sitedir definition from
configure.ac.
This changes the usage of some of the jit_local_state fields, and add
two extra ones. Since jit_arg_x now returns either a register offset or
an stack offset, it does not add _XMM0 to nextarg_putfp to distinguish
from stack offsets.
The nextarg_puti field is used to known when run out of integer register
arguments, and should push arguments on the stack.
The new framesize field is used to keep track of jit_arg_x offset on
the stack, when jit_arg_x runs out of registers.
The argssize field is used in a slightly different way now, and is
used to keep track of number of stack slots used to pass arguments, and
nextarg_puti is used in its previous semantics, to also match nextarg_putfp
logic.
It is required to set %al to 0-8 inclusive, telling the number of
xmm registers used to pass arguments.
This also corrects the calculation of _jitl.nextarg_putfp, that
would be incorrect if calling a function with both, float and double
arguments.
Lightning provides at least 6 float registers, so, in this commit,
reduce from 8 to 7 so that code respecting JIT_FPR_NUM should be
safe again't use of JIT_FPTMP.
To not clobber JIT_R2, JIT_REXTMP is defined to the callee save register
%r12, instead of the expected, scratch register %r11.
To have JIT_V_NUM at least at 3, it now also uses %r14, but does not add
%r15, that could be JIT_V(4) to simplify logic of keeping stack 16 bytes
aligned.
