Peter Johnson	6591a155d0	Check for circular equ references (Bug#8). svn path=/trunk/yasm/; revision=723	22 years ago
Peter Johnson	a3a9fd2aa0	Completely revamp how label resolution is done (part of Bug#6). Now calculates /distances/ between bytecodes in a section using bc_calc_dist() functions (a "typical" one is provided for most occasions). expr_expand_labelequ() is gone, as its functionality is integrated into expr_simplify(). Currently these changes break most bin objfmt output, as it doesn't know how to resolve absolute labels yet. Also, very preliminary expr support for :, SEG, and WRT operators has been added (part of Bug#2). Several other minor bug fixes. svn path=/trunk/yasm/; revision=718	22 years ago
Peter Johnson	c40005c223	Update comment for sym_table variable. svn path=/trunk/yasm/; revision=717	22 years ago
Peter Johnson	622e01725a	The data argument to section_data_print() can never be null. svn path=/trunk/yasm/; revision=710	22 years ago
Peter Johnson	e9e00fcef2	errwarn_new(): Fix bug that could cause infinite loops. svn path=/trunk/yasm/; revision=709	22 years ago
Peter Johnson	090a25b8d4	Rename intnum_new_int to intnum_new_uint, and add new signed version of intnum_new_int. Currently only just calls intnum_new_uint with a cast, but eventually there may be a better way of handling signed numbers. svn path=/trunk/yasm/; revision=708	22 years ago
Peter Johnson	4f8f5b128f	InternalError on unrecognized operations rather than just dropping them. svn path=/trunk/yasm/; revision=707	22 years ago
Peter Johnson	b7a8747102	Move yasm core files into a libyasm shared library (avoiding backlinking). Some cleanups still needed; a few things in globals should really be somewhere else, or named differently. svn path=/trunk/yasm/; revision=705	22 years ago
Peter Johnson	ba294928c6	Move cur_parser from globals to main (as it's only used in main). svn path=/trunk/yasm/; revision=704	22 years ago
Peter Johnson	c5ef1bf2dc	Eliminate duplicate code for callbacks from expr_expand_labelequ() by moving code and adding a resolve_precall function parameter (which caused cascading changes in bytecode-related sources). svn path=/trunk/yasm/; revision=701	23 years ago
Peter Johnson	4a4fd6be7d	Support dynamic linking for objfmts, and make bin and dbg both dynamically loadable. svn path=/trunk/yasm/; revision=700	23 years ago
Peter Johnson	5f02a6f596	Re-add a hackish fix to set initial bits setting from objfmt for x86 arch. svn path=/trunk/yasm/; revision=698	23 years ago
Peter Johnson	3320945f95	Massive restructuring of lexing and parsing (NASM-compatible parser). Bugzilla Bug#3. Not all instructions are parsed yet, so this is actually a minor feature regression from the user side, but this commit lays the framework for much easier additions of new assembler syntaxes and architectures. The re2c tool is now used to generate the lexers, as it's much more flexibly function-oriented than lex. - nasm-bison.y is a repocopy+modify of nasm/bison.y.in. - x86arch.h now includes all of x86-int.h svn path=/trunk/yasm/; revision=670	23 years ago
Peter Johnson	45333b0225	Allow objfmt initialize and cleanup function pointers to be NULL when not needed. svn path=/trunk/yasm/; revision=663	23 years ago
Peter Johnson	da070d5964	Move strndup() declaration outside !DMALLOC #ifdef, as it's not defined by the dmalloc library. svn path=/trunk/yasm/; revision=661	23 years ago
Peter Johnson	77be8f8662	vps_print() should take a const valparamhead *. svn path=/trunk/yasm/; revision=659	23 years ago
Peter Johnson	ac8d8e085a	Declare errwarn_new(), error_common(), and warning_common() as static. svn path=/trunk/yasm/; revision=652	23 years ago
Peter Johnson	f78505a6a5	Add xstrndup() to easily create a 0-terminated duplicate of a non-zero-terminated source string. svn path=/trunk/yasm/; revision=649	23 years ago
Peter Johnson	f8f1c204f7	Bytecode and objfmt changes: - Add two new bytecode types: BC_ALIGN (not yet implemented) for performing nice alignment magic. BC_OBJFMT_DATA for storing objfmt-generated data in more advanced objfmts. - objfmt structure changes: Add handling functions for BC_OBJFMT_DATA data. Allow a number of functions to be NULL. svn path=/trunk/yasm/; revision=631	23 years ago
Peter Johnson	ac2743de63	Prevent spurious "Circular reference detected" errors by refining the return value for bc_resolve() to enum-defined flags. svn path=/trunk/yasm/; revision=623	23 years ago
Peter Johnson	4fed536d3c	Revamp error/warning handling. svn path=/trunk/yasm/; revision=622	23 years ago
Peter Johnson	4407d49d66	During the first pass of basic optimization, continue reporting errors, don't stop at the first error. To help prevent spurios errors, make bytecodes with errors 0 length in bc_resolve(). svn path=/trunk/yasm/; revision=621	23 years ago
Peter Johnson	58cc15c1d6	Change handling of res* (no longer require that the entire containing buffer be allocated and filled with 0's to write it out). Other fixes: Specifically look for floating point values in res* and multiple exprs. One-byte PC-relative displacement is legal (short jumps). svn path=/trunk/yasm/; revision=620	23 years ago
Peter Johnson	0703225136	A number of fixes to float and integer handling on the output side: - expr can now negate floatnums - bin objfmt output_expr now correctly outputs all sizes of integers and does a check for floating point containing exprs before complaining about external references. Also checks for properly sized floatnum output with an ErrorAt instead of an InternalError. svn path=/trunk/yasm/; revision=618	23 years ago
Peter Johnson	4fc6605a56	Properly count errors and warnings triggered by ErrorAt() and WarningAt(). svn path=/trunk/yasm/; revision=617	23 years ago
Peter Johnson	0d91497dd1	Have symrec manage all symbols, not just the ones in the symbol table. svn path=/trunk/yasm/; revision=608	23 years ago
Peter Johnson	db0c353f68	Switch back to returning @dependent@ instead of @observer@. svn path=/trunk/yasm/; revision=607	23 years ago
Peter Johnson	590fc49113	Splint cleanups, including const change. svn path=/trunk/yasm/; revision=605	23 years ago
Peter Johnson	6033703a64	Splint cleanups and related bugfixes: - fix memory leak in bin_objfmt_resolve_label2() - delete common data in bin_objfmt_common_data_new() rather than continuing to handle it in declare_data_*() svn path=/trunk/yasm/; revision=604	23 years ago
Peter Johnson	f11e97b9ec	Change most Splint return annotations from dependent to observer. Also, section_get_start() can't return NULL. svn path=/trunk/yasm/; revision=603	23 years ago
Peter Johnson	848dab8ff0	Cast SAVE_* and WRITE_* assignments to unsigned char. svn path=/trunk/yasm/; revision=602	23 years ago
Peter Johnson	f8bfa83597	Make expr_print() take a const expr. svn path=/trunk/yasm/; revision=601	23 years ago
Peter Johnson	a6f0bff972	Splint cleanups: expr_copy_* don't take a NULL, so they can't return NULL. svn path=/trunk/yasm/; revision=599	23 years ago
Peter Johnson	bb71f908bc	Splint cleanups. svn path=/trunk/yasm/; revision=598	23 years ago
Peter Johnson	a6d468b938	Splint cleanups. svn path=/trunk/yasm/; revision=595	23 years ago

Peter Johnson	9398eb518e	Add some splint-suggested cleanups. svn path=/trunk/yasm/; revision=551	23 years ago
Peter Johnson	aa6f573370	Update DISTFILES to reflect src/lclint.sh -> splint.sh move. svn path=/trunk/yasm/; revision=550	23 years ago
Peter Johnson	bccc5e7ec7	When using Splint, don't try to use gettext(). svn path=/trunk/yasm/; revision=547	23 years ago
Peter Johnson	04df0be842	Cleanups both for and from Splint. svn path=/trunk/yasm/; revision=546	23 years ago
Peter Johnson	c738bd3f9d	Recursively expand EQU's. svn path=/trunk/yasm/; revision=531	23 years ago
Peter Johnson	adfc2e10c9	Add expr_get_floatnum(). svn path=/trunk/yasm/; revision=529	23 years ago
Peter Johnson	fe8c2a009f	Restructure bc_calc_len() family into bc_resolve() family. Many many many bugfixes to the bc_tobytes() family and other functions. Binary object output is now close to complete: just a few more bugs to kill! svn path=/trunk/yasm/; revision=528	23 years ago
Peter Johnson	c9e4019b28	Comment additions. svn path=/trunk/yasm/; revision=526	23 years ago
Peter Johnson	d85e7014a8	Binary object format output! Lots of structural changes needed, particularly with regards to resolve_label(). MAJOR FIXME: The tobytes() pass acts like a final optimization pass. This causes internal errors because of length mismatches (optimized to shorter len). svn path=/trunk/yasm/; revision=521	23 years ago
Peter Johnson	d2a2e6b3f8	Add bcs_last() macro. svn path=/trunk/yasm/; revision=496	23 years ago
Peter Johnson	c9d73bae1e	Make duplicate definition (w/regards to COMMON and EXTERN) work properly. svn path=/trunk/yasm/; revision=493	23 years ago
Peter Johnson	07c3299820	Add bin object format. Changes to: objfmt interface: added parameter to directive() for sections access. section interface: moved start to be present for all section types. basic optimizer: add section start to offset determination. (much of the section start changes are due to the need to make sure offsets don't end up being optimized into byte-sized offsets that can't be relocated). svn path=/trunk/yasm/; revision=490	23 years ago
