support. Also do not clobber the entire x87 stack for atan, sin, and
cos rules.
2007-01-12 Heiko Weiss <heiko.weiss@de.trumpf-laser.com>

and change patterns of TRUNC rules to have a separate destination
register.
2006-10-16 Aleksey Demakov <ademakov@gmail.com>
* jit/jit-interp.h, jit/jit-interp.c (_jit_run_function):
* jit/jit-opcode.c, jit/jit-rules-interp.c (_jit_gen_insn): Repair
struct handling broken since the last interpreter reorganization,
remove unused interpreter opcodes.
* jit/jit-rules-interp.c (_jit_gen_start_block): check if the fixup
position is before the cache end. This prevents segmentation fault
when the end of cache block is reached and jit_function_compile()
attempts to generate more code (it checks for the cache end way too
libjit/ChangeLog view on Meta::CPAN
previously it was always assigned to a separate register. Also
restructure the code that will be used for better selection of x87
instructions (this code was not used before and still is not but
this is about to change).
* jit/jit-rules-x86.ins: rewrite all LOAD_RELATIVE and LOAD_ELEMENT

* jit/jit-reg-alloc.c (use_cheapest_register): allow a register that
contains an input value to be used as a scratch register. The input
value in this case is copied to another register. This resolves the
problem with JIT_OP_IREM rule that failed to allocate a scratch reg
in a very specific case (all EBX, ESI, EDI regs are used as global,
dividend is initially in ECX and copied to EAX:EDX pair where x86
idiv expects it to be).
* jit/jit-reg-alloc.c (set_regdesc_flags): fix a bug.

* jit/jit-apply-alpha.c jit/jit-gen-alpha.h jit/jit-rules-alpha.h
jit/jit-rules-alpha.c: Implement closure for alpha. Use jsr
instead of bsr in alpha_call. Clean up prolog and epilog
generation for alpha to be more readable.

JIT_OP_TRUNC_SBYTE, JIT_OP_TRUNC_UBYTE, JIT_OP_LOAD_PC rules.
* jit/jit-rules-x86.c (_jit_opcode_is_supported): include .inc file
instead of .slc if USE_NEW_REG_ALLOC is defined.
libjit/ChangeLog view on Meta::CPAN
may be used by the code generator as a hint. However currently the
code generator does not use such a hint. The old code is kept for
reference #ifdefed out.
2006-06-17 Aleksey Demakov <ademakov@gmail.com>
* jit/jit-reg-alloc.h, jit/jit-reg-alloc.c: implement support of the
JIT_REGS_FREE_DEST flag for 3-argument instructions. Tweak reg alloc
API.
* tools/gen-rules-parser.y: adjust for reg alloc API changes. Use
'$0' pattern element to refer to destination register in 3-argument
instructions.
* jit/jit-rules-x86.ins: rewrite JIT_OP_IDIV, JIT_OP_IDIV_UN,
JIT_OP_IREM, JIT_OP_IREM_UN, JIT_OP_ADDRESS_OF_LABEL,
JIT_OP_LOAD_RELATIVE_FLOAT32, JIT_OP_LOAD_RELATIVE_FLOAT32,

JIT_OP_IREM rules for the divisor value of -1.
2006-06-09 Aleksey Demakov <ademakov@gmail.com>
* jit/jit-rules-x86.ins: rewrite JIT_OP_STORE_RELATIVE_BYTE,
JIT_OP_STORE_RELATIVE_SHORT, JIT_OP_STORE_RELATIVE_LONG,
JIT_OP_STORE_RELATIVE_FLOAT32, JIT_OP_STORE_RELATIVE_FLOAT64,
JIT_OP_STORE_RELATIVE_NFLOAT, JIT_OP_STORE_ELEMENT_LONG,
JIT_OP_STORE_ELEMENT_NFLOAT rules to use regular pattern
syntax instead of manual.
2006-06-03 Aleksey Demakov <ademakov@gmail.com>

JIT_OP_RETURN_FLOAT32, JIT_OP_PUSH_FLOAT32, JIT_OP_RETURN_FLOAT64,
JIT_OP_RETURN_NFLOAT, JIT_OP_PUSH_FLOAT64, and JIT_OP_PUSH_NFLOAT
rules. With new ``gen-rules'' tool it frees wrong register and
the right register is anyway freed automatically by the new
allocator.
* jit/jit-reg-alloc.h, jit/jit-reg-alloc.c (_jit_regs_abort): add
function to unbind values from registers if the code generation
failed. This is required because new allocator may temporary bind
constants to registers and if neither _jit_regs_commit() nor
_jit_regs_abort() is called the constant value will be left in
inconsistent state. The problem shows up when the end of a cache
block has been reached and the compilation is restarted with a new
block.
* jit/jit-reg-alloc.c (_jit_regs_begin, _jit_regs_end): add
convenience functions.
* tools/gen-rules-parser.y (gensel_output_clauses): make generated
code more readable by using _jit_regs_begin() and _jit_regs_end()
where appropriate.
* jit/jit-reg-alloc.c: allow to load the second part of a register
pair to a global register. This is because x86 long arithmetics
use 4 registers at once: EAX:EDX and ECX:EBX. At the same time
EBX is the global register candidate. If the instruction clobbers
the global register, the new allocator automatically pushes it on
the stack before and pops after the instruction.
* jit/jit-function.c (compile_block): modify trace messages.
2006-05-28 Klaus Treichel <ktreichel@web.de>
* jit/jit-insn.c: Add a code_label in initialize_setjmp_block just
before the end_label that is moved with the block to the start of
the function as jump target to the code. Otherwise other blocks
moved to the start after this block will never be executed.
2006-05-27 Aleksey Demakov <ademakov@gmail.com>
* jit/jit-reg-alloc.c (free_value, save_value): the value that has
a global register and is also associated with a local register
needs to be unbound from the local one.
* jit/jit-reg-alloc.c (compute_spill_cost): assume that the spill
cost for clean values is not zero. This keeps them in registers
as long as there are free registers and thus reduces the number of
loads.
2006-05-25 Aleksey Demakov <ademakov@gmail.com>
* jit/jit-reg-alloc.c (use_cheapest_register): fix cost calculation
again for 'spill_before' rules. The last patch did not work for
values stored in global registers. Now both global and non-global
values should be copied to EAX.
2006-05-25 Aleksey Demakov <ademakov@gmail.com>
* jit/jit-reg-alloc.c (use_cheapest_register): fix cost calculation
that sometimes caused overlooking free registers. This was a serious
problem as there are some 'spill_before' rules that assume that the
allocator will always choose EAX as the first free register.
2006-05-21 Aleksey Demakov <ademakov@gmail.com>
* jit/jit-reg-alloc.h: add _JIT_REGS_FREE_DEST flag to be used in
cases when the destination register is independent of any input
register.
* tools/gen-rules-parser.y: allow specification of independent
destination register with '=reg' pattern syntax. (But the allocator
does not yet handle this.)

register index.
* jit/jit-reg-alloc.c (_jit_regs_assign): micro optimization by
changing nesting order of for and if statements.
2006-05-19 Aleksey Demakov <ademakov@gmail.com>
* jit-reg-alloc.h, jit/jit-reg-alloc.c: determine if input values
need to be saved and evicted from registers to stack frame at the
_jit_regs_assign() time. Uniformly save input values that need to
in _jit_regs_gen(), do not save them in _jit_regs_commit(). This
simplifies handling of stack registers. Remove initial_stack_top,
exchanges, num_exchages fields from the _jit_regs_t struct. Add
save and kill bit fields to the _jit_regdesc_t struct. Refactor
and clean up code.
2006-05-10 Aleksey Demakov <ademakov@gmail.com>
* jit/jit-reg-alloc.c (use_cheapest_register): check if the other
part of a register pair clobbers global registers.

if we do register exchanges for other values.
* jit/jit-reg-alloc.c: set touched registers more accurately.

* configure.in, NEWS: update version for the "0.0.2" release.
* configure.in: updating working version to "0.0.3".
2004-05-12 Rhys Weatherley <rweather@southern-storm.com.au>
* jitdynamic/Makefile.am, jitplus/Makefile.am: use both .libs and
non.libs versions of the so paths, because some versions of libtool
add .libs implicitly and others don't.
* dpas/dpas-builtin.c, dpas/dpas-parser.y, dpas/dpas-types.c,
dpas/dpas-types.h: add the "SameType" and "SameShape" builtins,
to assist with unit testing type coercions.
* dpas/dpas-parser.y (IfTail): fix a bug that caused the "then"
case of an "if" to fall through to the "else".
* dpas/dpas-parser.y: resolve ea-based lvalues in operators.
* include/jit/jit-defs.h.in: incorrect values for jit_max_int
and jit_max_long.
* dpas/dpas-scanner.l (dpas_parse_hex): ignore the 'H' on the
end of a hexadecimal constant.
* Makefile.am, configure.in, tests/.cvsignore, tests/Makefile.am,
tests/coerce.pas: check in some initial infrastructure for the
dpas-based test suite.
* jit/jit-type.c (jit_type_promote_int): promote ubyte and ushort
to uint, not int.
* jit/jit-insn.c, tests/coerce.pas: more coercion test cases and fixes.
* dpas/dpas-builtin.c, jit/jit-dump.c, jit/jit-value.c: add builtins
for mathematical operations.
* dpas/dpas-parser.y, jit/jit-interp.cpp, tests/Makefile.am,
tests/math.pas: test cases and bug fixes for mathematical operations.
* dpas/dpas-main.c, include/jit/jit-context.h, jit/jit-context.c,
jit/jit-insn.c, tests/Makefile.am: add the "--dont-fold" option
to Dynamic Pascal, so that we can run the test cases without folding.
* tests/README: add a README file to describe how to write test cases.
2004-05-11 Rhys Weatherley <rweather@southern-storm.com.au>
* include/jit/jit-insn.h, jit/jit-insn.c, jit/jit-interp.cpp,
jit/jit-interp.h, jit/jit-opcode.c, jit/jit-rules-interp.c:
round out the function call handling opcodes for the interpreter.
* jit/jit-rules-interp.c, jit/jit-rules-interp.h: implement
the exception-handling opcodes for the interpreter.
* dpas/dpas-parser.y, dpas/dpas-scope.c, dpas/dpas-scope.h:
fix a bug that caused global variables in Dynamic Pascal
to be incorrectly allocated as locals.
* jit/jit-reg-alloc.c (_jit_regs_load_to_top_two): handle the
case where the second value is on the stack but not the first.
* dpas/dpas-parser.y, dpas/dpas-types.c, dpas/dpas-types.h:
report errors for unimplemented expressions and statements,
so that users are not "surprised" when things silently fail.
* .cvsignore, auto_gen.sh, configure.in, doc/.cvsignore,
dpas/.cvsignore, dpas/Makefile.am, include/.cvsignore,
jit/.cvsignore, jit/Makefile.am, jitdynamic/.cvsignore,
jitdynamic/Makefile.am, jitplus/.cvsignore, jitplus/Makefile.am,
tools/.cvsignore, tutorial/.cvsignore, tutorial/Makefile.am:
modify the autoconf/automake build system to use libtool.
2004-05-10 Rhys Weatherley <rweather@southern-storm.com.au>
* jit/jit-reg-alloc.c, jit/jit-reg-alloc.h, jit/jit-rules-interp.c:
interpreter code conversion for relative pointer and copy opcodes;
fix some bugs in stack-based register allocation.
* dpas/dpas-parser.y, dpas/dpas-types.c, dpas/dpas-types.h:
loading and storing record fields in Dynamic Pascal.
* dpas/dpas-builtin.c: implement the "New" and "Dispose" builtins.
2004-05-08 Rhys Weatherley <rweather@southern-storm.com.au>
* jit/jit-cache.c, jit/jit-cache.h, jit/jit-dump.c, jit/jit-interp.h,
jit/jit-rules-interp.c: add "_jit_cache_get_end_method", to allow
the end of a method's code to be located without explicit marking.
* configure.in, include/jit/jit-util.h, jit/jit-string.c:
remove the locale-sensitive string comparison routines because
they aren't used in libjit, and front ends will normally have
their own functions for this purpose.
* Makefile.am, configure.in, doc/Makefile.am, doc/libjit.texi,
include/jit/Makefile.am, include/jit/jit-dynamic.h,
include/jit/jit-util.h, jit/Makefile.am, jit/jit-dynlib.c,
jit/jit-mangle.c, jitdynamic/.cvsignore, jitdynamic/Makefile.am,
jitdynamic/jit-cpp-mangle.c, jitdynamic/jit-dynlib.c:
move the dynlib and C++ name mangling routines into a separate
"jitdynamic" library, which will handle all of the cross-language
naming and dynamic invocation logic.
* include/jit/jit-type.h, jit/jit-internal.h, jit/jit-type.c,
jitdynamic/jit-cpp-mangle.c: move the "JIT_TYPE_xxx" constants
into the public headers and add "jit_type_get_kind" so that
front end code can classify types quickly.
* jit/jit-dump.c: use "objdump" to dump compiled native code.
2004-05-07 Rhys Weatherley <rweather@southern-storm.com.au>
* dpas/dpas-function.c, dpas/dpas-internal.h, dpas/dpas-main.c,
dpas/dpas-parser.y, jit/jit-interp.cpp, jit/jit-interp.h,
jit/jit-opcode.c, jit/jit-rules-interp.c: execute the "main"
method once a Dynamic Pascal program has been compiled;
( run in 0.482 second using v1.01-cache-2.11-cpan-f6376fbd888 )
