Users who build out of SVN will need to install Python, but this is painless even for
Windows users

Delete generated files from SVN; these are massive and annoying to keep updated

This combines the C and perfect hash tables into a single source file,
and allows for easier future changes to the source-level structures.
The Python-built files are included in the distribution so that Python
is not added as a dependency.
The generated code has been verified equal against the old tables,
excepting a number of bugfixes.
Most of the bugs fixed are in the CPU field, plus a few GAS suffix fixes.

* x85geninsn.c: Clean up a couple of unused variables.

tab size is ever not 8. While I debated converting to tab-only indentation
that would have been a far higher impact to the source.

This commit adds the necessary directives and some higher-level macros to
make it easier to generate the .xdata and .pdata sections needed for
structured exception handling on Win64. The overall construction mirrors
MASM very closely, so it should be possible for near-direct translation of
MASM code to Yasm; see for example objfmts/win64/tests/sce3.masm and
objfmts/win64/tests/sce4.asm. This commit does *not* break generating these
yourself (which you may want to do if you're a compiler).
This commit adds special proc macros so the function layout will look like:
proc_frame <procname>
... (frame setup and unwind directives)
end_prologue (or alternatively [endprolog])
...
endproc_frame
The "raw pseudo operations" (.directives) as described in MSDN
(http://msdn2.microsoft.com/en-us/library/ms235231(VS.80).aspx)
have been exactly mirrored in Yasm, as follows:
[pushreg], [setframe], [allocstack], [savereg], [savexmm128], [pushframe],
[endprolog]
Note the [] are required.
Additionally, the following macros have been implemented that MASM provides
in ksamd64.inc, and as documented in MSDN
(http://msdn2.microsoft.com/en-us/library/ms235217(VS.80).aspx):
push_reg, rex_push_reg, push_eflags, rex_push_eflags, alloc_stack,
save_reg, save_xmm128, push_frame, set_frame, end_prologue
I'll next work on getting all of this documented in the user manual.

rather than simply taking a list of modules on the command line. This allows significant
improvement of the behavior when used with Visual Studio, as the "old" way of doing this
with Visual Studio build files was to scan through the .c files; this brought up things
that were actually disabled in the build.
Also incorporate a patch by Charles Bailey to make the VC8 build less noisy, and allow use
of Win32 Bison if it's installed. Instructions updated as well.

handling. The new way of doing things follows C compiler standard path
searching rules in terms of relative and absolute paths in relation to

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.

instead of re2c-generated code. This gives identifier recognition a
significant speedup and also drastically shortens compilation time of yasm
itself. This rewrite encouraged combining instruction and prefix
recognition into one function and register and target modifier
recognition into a second function (rather than having 5 or so separate
functions).
Also created a state in the NASM parser (as was done in the GAS parser),
so instructions/prefixes are only looked for until an instruction is
recognized. This avoids search time in the instructions hash for operands.
The tool used to generate the new identifier recognition is called GAP.
Someday we might extend this to generate more code than just the perfect
hash lookup.
* tools/gap: New tool to Generate Architecture Parser (aka perfect hashes).
* phash.c, phash.h: Helper functions used by GAP-generated code.
* x86id.re: Delete. Split into..
* x86parse.gap: Contains all identifier recognition portions.
* x86id.c: Contains instruction operand tables and code and higher-level
entry points into x86parse.gap perfect hash recognizers. Chose to flow
history of x86id.re into this file.
* arch.h: Combine instruction/prefix entry points and register/target
modifier entry points.
* lc3barch.c, lc3bid.re, lc3barch.h: Update to match.
* x86arch.c, x86arch.h: Update to match.
* Makefile.am, various Makefile.inc: Update.
* POTFILES.in: Update due to numerous file changes (not just this commit).
* Mkfiles: Update. VC build files untested at the moment.
svn path=/trunk/yasm/; revision=1395
The fix for this rippled into a lot of places, and I'm starting to see some
opportunities for cleaning up some of the object and objfmt structures.
* objfmt.h (yasm_objfmt_add_default_section): Move from standalone function
into objfmt-specific function.
(yasm_objfmt_module): Remove default_section_name string, and add objfmt
specific add_default_section function.
* yasm.c (main): Use slightly updated parameters when calling.
* section.h (yasm_section_is_default, yasm_section_set_default): New.
* section.c (yasm_section): Add def member (for default section flag).
(yasm_section_is_default, yasm_section_set_default): Implement.
* xdf-objfmt.c, bin-objfmt.c, dbg-objfmt.c, coff-objfmt.c: Implement.
Usually this required refactoring the objfmt-specific section data creation
into a separate function that could be used by both section_switch() and
the new add_default_section() functions, and changing section_switch() to
update changes to the section data if section was new or previously just a
default section, instead of the previous behavior of warning if the section
was not new.
* objfmt.c: Delete (no longer needed).
* Makefile.inc, Makefile.flat, libyasm.vcproj
Makefile.dj: Update to reflect removal.
* xdf-overdef.asm, win32-overdef.asm, elf-overdef.asm: Test.
