* check/clobber.ok, check/clobber.tst: New test case doing
extensive validation tests to ensure registers not used in
a operation are not clobbered.
* check/Makefile.am: Update for new test case.
* check/stack.ok, check/stack.tst: New files to test data
integrity on a deep chain of stack frames.
* lib/jit_arm.c, lib/jit_arm-cpu.c, lib/jit_mips.c,
lib/jit_mips-cpu.c, lib/jit_ppc.c, lib/jit_ppc-cpu.c,
lib/jit_x86.c, lib/jit_x86-cpu.c: Calculate _jit->function->stack
in the emit stage, otherwise it will calculate it wrong if
need to jit_allocai space to spill registers.
* lib/lightning.c: Correct wrong offset when updating the
"current" jit function pointer in the code that may need to
allocate stack space to spill registers.
* check/lightning.c: Correct off by one data space check.
* check/Makefile.am: Update for new test case.
* check/fop_abs.ok, check/fop_abs.tst, check/fop_sqrt.ok,
check/fop_sqrt.tst: New files implementing simple test cases
for the extra float operations.
* check/Makefile.am: Update for new test cases.
* check/alu.inc: Add an extra macro to check for unordered
equality on tests where it is expected to use NaN as an
argument.
* check/lightning.c: Minor change for proper/common argument
syntax handling ommiting arguments to options.
* check/Makefile.am: Automatically generate pattern list
of tests with alternate jit generation options. This should
prevent typos and needing to change multiple places after
a change.
* check/lightning.c: Remove the ".cpu name value" syntax,
as it was not able to do proper changes before the jit
internal data structure was initialized. Now it supports
several getopt options to force using different jit
generation options, effectively replacing the previous
syntax.
* check/run-test: Add simple extra logic to handle differently
named test scripts, used to test things like x87 coprocessor
in ix86, and arm instruction set or software float in armv7l.
* configure.ac: Add some AC_RUN_IFELSE calls to figure at
compile time if can test different code generation options,
and update Makefile generation accordingly.
* check/Makefile.am, lib/jit_arm.c, lib/jit_x86.c: Update to
properly work with the test tool updating the jit_cpu global
information.
* check/check.arm.sh, check/check.swf.sh, check/check.x87.sh:
New wrapper files passing -mthumb=0, mvfp=0 and -mx87=1 to
the test tool, if applicable, so that it can validate alternate
code generation options on test hosts that support them.
* include/lightning.h, lib/jit_arm.c, lib/jit_mips.c,
lib/jit_ppc.c, lib/jit_x86.c, lib/lightning.c: Change jit_prepare
to no longer receive an argument. If receiving an argument, it
should be an ABI specifier, not a boolean if varargs or not,
and add the new jit_ellipsis call, to specify where the
ellipsis is in the C prototype of the function being called.
Note that currently it is not supported to define varargs
functions and it will be ignored if calling jit_ellipsis not
in a prepare/finish* block, but this should be addressed.
* check/allocai.tst, check/alu_add.tst, check/alu_and.tst,
check/alu_com.tst, check/alu_div.tst, check/alu_lsh.tst,

check/ldstxr-c.tst, check/ldstxr.tst, check/rpn.tst,
check/lightning.c: Update for the change to jit_prepare and
addition of jit_ellipsis.

check/alu_xor.tst, check/alux_add.ok, check/alux_add.tst,
check/alux_sub.ok, check/alux_sub.tst, check/branch.ok,
check/branch.tst: New test cases for arithmetic and branch
tests.
* check/Makefile.am: Update for new test cases.
* include/lightning/jit_private.h: Make the jit_reg_free_p
macro shared by all backends. Previously was added for the
arm backend, but is useful in the x86_64 backend when checking
state of "special purpose register".
Also add the new jit_class_named register class, that must be
or'ed with the register value if calling jit_get_reg expecting
an specific value, because the specific register value may be
zero, that previously was treated as no register requested.
* lib/jit_arm-cpu.c: Correct argument order for T2_MVN.
* lib/jit_arm-swf.c: Call the proper function for double
divide. The "software float" implementation just calls
libgcc functions.
* lib/jit_arm.c: Return float/double values in the float
register if using the hard float ABI.
* lib/jit_x86-cpu.c: Change the can_sign_extend_int_p macro
to not include -0x80000000L, because there is code that
"abuses" it and thinks it can negate the immediate value
after calling that macro.
Correct implementation of jit_subi that had a wrong code
patch logic doing subtraction with reversed arguments.
Correct REX prefix calculation in the jit_muli implementation.
Correct logic to get/unget %*ax and %*dx registers in divremr
and divremi.
Correct divremi that was using the symbolic, unique %*ax
value in on place (not using the _REGNO name suffix).
Correct cut&paste error causing it to use "xor" instead of
"or" in one code path of the jit_ori implementation.
Correct several flaws when clobbering registers and/or when
one of the arguments was %*cx in the rotshr wrapper function
implementing most shift operations.
* lib/lightning.c: No longer expect that the backend be smart
enough to know what to do when asking for a named register
if that register is already an argument or is live. It fails
if it is an argument, or if register is live, fails if cannot
spill.
No longer incorrectly assume that eqr_{f,d} and ltgr_{f,d} are
safe to inverse value tests in jump thread optimization.
* check/Makefile.am, check/cvt.ok, check/cvt.tst: Add new
"cvt" test case to test conversion from/to int/float types.
* check/lightning.c: Only define truncr_{f,d}_l in 64 bit mode.
* include/lightning.h: Correct typo that caused it to define
jit_truncr_{f,d}_l in 32 bit mode.
* lib/jit_arm-cpu.c: Avoid assertion failure in the signed/unsigned
extend opcodes generation as it shares an interface for 3 argument
opcode generation.
* lib/jit_x86-cpu.c: Correct wrong argument passed to
jit_unget_reg in the andi implementation and wrong byte
unsigned extend code generation.
* lib/jit_x86-sse.c: Correct conversion from "word" to float or
double as is dependent on wordsize.
* check/ldstr-c.ok, check/ldstr-c.tst, check/ldstxi-c.ok,
check/ldstxi-c.tst, check/ldstxr-c.ok, check/ldstxr-c.tst:
New test case files testing load clobbering the base and/or
index register;
* check/ldst.inc: New file with common definition for all the
ldst* test cases.
check/Makefile.am, check/ldsti.tst, check/ldstr.tst,
check/ldstxi.tst, check/ldstxr.tst: Update for new common
definitions file and new register clobber ldst tests.
* check/ldstr.ok, check/ldstr.tst, check/ldsti.ok,
check/ldsti.tst, check/ldstxr.ok, check/ldstxr.tst,
check/ldstxi.ok, check/ldstxi.tst:
New test case files exercising a very large amount of
register combinations to verify load/store implementation.
* check/Makefile.am: Update for new test cases.
* lib/jit_x86-cpu.c: Correct wrong argument order when
computing REX prefix for {ld,st}r_T codes;
* lib/jit_mips-fpu.c, lib/jit_mips.c: Implement missing mips
jit_sqrtr_{f,d} codes.
* check/all.tst, include/lightning.h, lib/jit_print.c: Change
declaration order and call order in all.tst of {add,sub}c and
{add,sub}x. *c must be called before to set the carry and *x
second to use the carry and keep it set. The wrong call order
was causing all.tst to fail in mips, where a register is
allocated to keep a global carry state.
* configure.ac, include/lightning/jit_private.h, lib/jit_arm-cpu.c,
lib/jit_arm-swf.c, lib/jit_arm.c, check/Makefile.am: Correct
implementation of the arm backend port to build and pass the
current test cases. Tested on armv7 with softfp abi.
* lib/jit_disasm.c: Rename and change prototype of static
disassemble function as in the arm backend it is required
to access state information stored in the jit_state_t object.
* check/3to2.tst, check/add.tst: Correct test case code assuming
JIT_RO and JIT_RET are the same, and even if they are the same,
the logic was incorrect because it must always call jit_retval*
to fetch a function call return before any other instruction.
The arm backend hash a special condition if jit_retval is not
called, because "r0" is not JIT_R0, but is JIT_RET and *also*
the first argument for a called function, so JIT_RET must be
only used as an argument to jit_retval.
* TODO: New file listing important tasks to be resolved.
* check/all.tst, check/lightning.c: Only declare or use 64 bit
interfaces on 64 bit builds.
* check/fib.tst: Use simpler logic to not need preprocessor
conditionals for 32 or 64 bit.
* include/lightning.h: Only declare 64 bit macros on a 64 bit
build. Code using lightning must know about wordsize and the
jit generation limitations, also, this way it generates a
compile time failure, not a runtime assertion.
* include/lightning/jit_x86.h: Correct typo in macro name.
* lib/jit_arm.c, lib/jit_arm-cpu.c, lib/jit_mips.c,
lib/jit_mips-cpu.c, lib/jit_ppc.c, lib/jit_ppc-cpu.c,
lib/jit_x86.c, lib/jit_x86-cpu.c: Correct wrong code to get
current jit function pointer.
* lib/lightning.c: Move call to the simplify() optimization
to after register liveness is known. Previous code did work
by accident but now with proper test cases the problem was
noticed.
* lib/jit_disasm.c: Always cast bfd_vma to long long when
passing it as printf argument.
* lib/jit_ppc.c: Assign copyright ownership to FSF.
* lib/jit_x86-cpu.c: Correct integer multiplication that was
generating code with reversed register arguments.
* check/rpn.ok, check/rpn.tst: New test case file.
* .gitignore: Update pattern of ignored files.
* check/Makefile.am: Add rule to build liblightning.la dependency
in case of running "make check" before building the library.

New sample input for the new test program, loosely matching
several of the previous test cases.
* check/Makefile.am: New test suite makefile.
* check/check.sh, check/run-test: New wrapper files for the
new test suite.
* check/lightning.c: New file. The main driver of the new test
suite, that compiles to a parser of a very simple assembly like
language, generates jit and executes it.
* check/all.tst: New file. A generic debug and sample test file
with a directive to prevent it from being executed, and useful to
read disassembly of all possible instructions, using a fixed set
of registers.

written from scratch, only by <pcpa@gnu.org>, and have now
copyright assignment to the FSF. This is the core of the new
lightning rework. Previously it was integrated in code with
a garbage collector and several custom types like vectors and
hash tables, so this first code merge with lightning converts
that code into a library extracting only the jit bits, and at
first only for x86_64 GNU/Linux.
* lightning.h, m4/lightning.m4: Removed. These are no longer
required in the new lightning code.
.gitignore, Makefile.am, configure.ac: Update for the new
lightning code.
