current major and minor version but with subminor version = 99. All releases
and snapshots will have a build version of the current svn version. Version
information is put into predefined macros in the NASM preproc:
__YASM_MAJOR__, __YASM_MINOR__, __YASM_SUBMINOR__, __YASM_BUILD__,
__YASM_VERSION_ID__, __YASM_VER__.
__YASM_VER__ does not have the build version as part of the string, and
__YASM_VERSION_ID__ does not incorporate the build version.
If the build version is "HEAD" (or other non-numeric), __YASM_BUILD__ is
set to 0.

--version option to just displaying version, compile date, and very short
copyright message.

"pyrexc" look for the module instead.

Thanks to some magic in python-yasm/Makefile.inc and setup.py, this actually
plays nicely with automake distcheck.

handling. The new way of doing things follows C compiler standard path
searching rules in terms of relative and absolute paths in relation to
source location and the current working directory. There's probably some
latent bugs in this as I've not tested it on Windows yet.
This should make CodeView actually usable with included files.
* file.c (yasm__abspath_win, yasm__abspath_unix): Convert a relative path
into an absolute path. Code moved from:

are included.

is support for cross-section relative symbol references using "sym-$".
This generates a 32-bit relative relocation similar to those used for
cross-section jumps and calls.
The bugfix is that in Win64 output, RIP-relative relocations do something
special when there is an immediate value (or anything else) between the
value being relocated and the next instruction. E.g.
"shl dword [sym wrt rip], 5" needs to generate a REL32_1 relocation thanks
to the immediate byte following the RIP-relative value.
* symrec.c (sym_type): add SYM_CURPOS to track labels representing the
current assembly position (e.g. $ in NASM, . in GAS).
(yasm_symtab_define_curpos): New function to create symbols of this type.
(yasm_symrec_is_curpos): Check to see if symbol is SYM_CURPOS type.
(yasm_symrec_get_label, yasm_symrec_print): Update to handle SYM_CURPOS.

* gas-bison.y: Use yasm_symtab_define_curpos when defining '.'.
* nasm-bison.y: Use yasm_symtab_define_curpos when defining '$'.
* value.c (yasm_value_finalize_expr): Look for cross-section
"sym-SYM_CURPOS" combinations and generate curpos-relative value if found.
* coretype.h (yasm_value): Add ip_rel member to designate that curpos_rel
is set due to the value being IP-relative (rather than sym-curpos).
* value.h (yasm_value_initialize, yasm_value_init_sym): Initialize ip_rel.
* x86expr.c (yasm_x86__check_ea): Set ip_rel in addition to curpos_rel if
detected WRT rip.
* x86bc.c (x86_bc_insn_tobytes): Use ip_rel instead of curpos_rel when
adjusting for RIP-relative.
* coff-objfmt.c (coff_objfmt_output_value): Properly adjust output and
generate correct relocations for both curpos_rel and ip_rel. This
includes new generation of REL32_1, REL32_2, etc relocations.
* symrec.c, symrec.h (yasm_symtab_define_label2): Delete.
* coff-objfmt.c (stabs_debgfmt_generate_sections): Change to use
yasm_symtab_define_label() instead.

elf_gas64_curpos.asm: New tests for above.

way to write this is "4-(label-$$)" (same output generated).

groundwork for further features and possible cleanups.
Note: this commit changes the way in which relocations in the
COFF/Win32/Win64 target can be forced to reference a different symbol than
is being pointed to; instead of the ambiguous "trap+(trap.end-trap)" to get
the reloc to point at trap.end but reference the trap symbol, after this
commit "trap.end wrt trap" is the way to say this. This also reads a lot
more clearly and is not ambiguous. This should really only affect people
who write .pdata sections for Win64. See the
objfmts/win64/tests/win64-dataref.asm testcase for an example of usage.
This cleanup adds a new data structure, yasm_value, which is used for all
expressions that can be potentially relocatable. This data structure
splits the absolute portion of the expression away from the relative
portion and any modifications to the relative portion (SEG, WRT,
PC-relative, etc). A large amount of code in the new value module breaks
a general expression into its absolute and relative parts
(yasm_value_finalize_expr) and provides a common set of code for writing
out non-relocated values (yasm_value_output_basic).
All bytecode handling in both libyasm and the architecture modules was
rewritten to use yasm_values when appropriate (e.g. data values,
immediates, and effective addresses). The yasm_output_expr_func is now
yasm_output_value_func and all users and implementors (mainly in object
formats) have been updated to handle yasm_values.
Simultaneously with this change, yasm_effaddr and yasm_immval full
structure definitions have been moved from bc-int.h to bytecode.h.
The data hiding provided by bc-int.h was relatively minimal and probably
overkill. Also, great simplifications have been made to x86 effective
address expression handling.
svn path=/trunk/yasm/; revision=1419
correct detection of absolute section reference loops (fixing a crash case).
This is also needed for an ongoing rewrite of reloc/value handling.
* expr.c (expr_xform_bc_dist): Remove transformation of absolute section
references; move in changed form into...
(yasm_expr__level_tree): Here. The new code doesn't immediately calculate
the distance from the start of the absolute section to the referenced symbol;
rather it generates an expression for this quantity. As this actually adds
new absolute section refs to the tree, we can't expand with YASM_EXPR_SYMs,
otherwise we would expand multiple times. Thus we need a new
YASM_EXPR_SYMEXP type that thus does not get expanded. Unfortunately this
ripples changes a bit because everywhere *else* we look for YASM_EXPR_SYM,
we now need to look for YASM_EXPR_SYMEXP as well...
(expr_xform_bc_dist): Here.
(yasm_expr__copy_except): Here.
(yasm_expr_extract_symrec): Here.
(yasm_expr_get_symrec): Here.
(yasm_expr_print): Here.
* bin-objfmt.c (bin_objfmt_expr_xform): And here.
* expr-int.h (yasm_expr__type): Define new YASM_EXPR_SYMEXP.
* section.h (yasm_section_abs_get_sym): To implement above, we need to get
a symbol referencing the first bytecode in the absolute section. To avoid
creating redundant symrecs, one is generated for us now. This function
lets us get it in yasm_expr__level_tree().
* section.c (yasm_section_abs_get_sym): Implement.
(yasm_section): Add necessary SECTION_ABSOLUTE data.
(yasm_section_create_absolute): Create the symrec here.
* absloop-err.asm: New test for absolute section reference loops.
