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.

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.

(yasm_symrec_is_curpos): Prototype.
* 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.

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.
