Peter Johnson	29f7d9a917	New function: expr_get_symrec(). svn path=/trunk/yasm/; revision=338	24 years ago
Peter Johnson	d6d0cb8785	Add symrec_delete() for deleting non-table symbols. Use it from expr_delete(). Also allow the sect for labels to be NULL (special case for new directive handling code). svn path=/trunk/yasm/; revision=337	24 years ago
Peter Johnson	8178f883a5	Modify so that almost everything passes LCLint with the options in lclint.sh. This is actually worthwhile; I found and fixed a few bugs/edge cases while doing this. For more information on LCLint, see <http://lclint.cs.virginia.edu/>. svn path=/trunk/yasm/; revision=335	24 years ago
Peter Johnson	fc603c2900	Add RCSID(). svn path=/trunk/yasm/; revision=334	24 years ago
Peter Johnson	424c30fdaa	Allow symrec_foreach return value to be ignored (in lclint). svn path=/trunk/yasm/; revision=332	24 years ago
Peter Johnson	4df0191de8	lclint-ize gettext(). svn path=/trunk/yasm/; revision=331	24 years ago
Peter Johnson	9f97bcd9d0	Fix some nits found by lclint. Still something weird going on with list2 in mergesort(), according to lclint, but I haven't figured out if it's real or not. svn path=/trunk/yasm/; revision=330	24 years ago
Peter Johnson	21eb7c7fe2	Add some lclint annotations. svn path=/trunk/yasm/; revision=329	24 years ago
Peter Johnson	d7fe402fb9	Split away x86-specific parts of expression handling (eg, effective address -> ModRM+SIB). svn path=/trunk/yasm/; revision=328	24 years ago
Peter Johnson	f58d7cb093	Split x86-specific stuff away from bytecode. svn path=/trunk/yasm/; revision=316	24 years ago
Peter Johnson	c9d92847b6	Start framework for separating architecture-dependent functions and data structures from the rest of the assembler. We're not trying to write GAS here (yet :), but doing this will make large parts of the codebase a lot clearer. svn path=/trunk/yasm/; revision=314	24 years ago
Peter Johnson	a7ac50c918	Add coretype.h, make util.h do a lot more, use util.h to simplify include sections of C files. Also remove IdPath from top comment in files where RCSID() is used. Move RCSID() to immediately after util.h include. svn path=/trunk/yasm/; revision=313	24 years ago
Peter Johnson	405df52913	bytecode_print(): Change how NULL values are output for imm and multiple. bytecode_parser_finalize_insn(): Add some preliminary imm handling. Handle shift_op special-casing (,1 hack). svn path=/trunk/yasm/; revision=312	24 years ago
Peter Johnson	665eddf5d7	Conditional x* prototypes on !DMALLOC (as they're defined by dmalloc.h if DMALLOC is enabled). svn path=/trunk/yasm/; revision=311	24 years ago
Peter Johnson	79e945c33c	Optimize expression building a bit in expr_new() by eliminating IDENT's here. This saves a lot of extra unnecessary recursions when the expr gets to the simplification stage. svn path=/trunk/yasm/; revision=310	24 years ago
Peter Johnson	ad7cbcea04	Add memory expressions tests (checkea). Split off errwarn functions so that they can be overridden in test cases. svn path=/trunk/yasm/; revision=309	24 years ago
Peter Johnson	00788fa80c	Fix errors found in expr_level_op() and checkea_calc_displen() by new test cases. svn path=/trunk/yasm/; revision=308	24 years ago

Peter Johnson	dc1c3c70f5	Get rid of all the extra filename strdup()'s. (Bug #14 ). svn path=/trunk/yasm/; revision=300	24 years ago
Peter Johnson	7a6eaf8c03	Make InternalError() a bit easier to call. Also, reverse its file and line parameters to match the *At() functions. svn path=/trunk/yasm/; revision=299	24 years ago
Peter Johnson	6f708e3034	Add xfree() to replace calls to free(). This also fixes the build breakage caused by removing stdlib includes. svn path=/trunk/yasm/; revision=298	24 years ago
Peter Johnson	adf5a95e89	Add option for malloc debugging using dmalloc library (http://dmalloc.com/). Remove unnecessary stdlib includes (because we use xmalloc instead of malloc). svn path=/trunk/yasm/; revision=297	24 years ago
Peter Johnson	21c598f9f8	Put in temporary implementations of ErrorAt() and WarningAt(). svn path=/trunk/yasm/; revision=296	24 years ago
Peter Johnson	e7bab50cf2	Parse NOSPLIT. Move some work to subfunctions in expr so they can be used for both 16-bit and 32-bit checking. svn path=/trunk/yasm/; revision=295	24 years ago
Peter Johnson	121f93b0a0	COMPLETELY rewrite most of expression handling. Features: - More complex memory expressions like [bx-(bx-di)] are now calculated through as valid. - Much better simplification. Internal changes: - More flexible n-way tree (rather than old binary-only). - Many new functions to simplify and deal with very complex expressions. svn path=/trunk/yasm/; revision=294	24 years ago
Peter Johnson	0a98a74163	Add mergesort() replacement from BSD sources. svn path=/trunk/yasm/; revision=292	24 years ago
Peter Johnson	cdcf358af1	RCSID() breaks under DJGPP because of "__unused". Removing __unused shouldn't cause any problems, really, so just removed it. svn path=/trunk/yasm/; revision=291	24 years ago
Peter Johnson	e640f25da5	Update comment on disp.len to match changes in expr.c. svn path=/trunk/yasm/; revision=288	24 years ago
Peter Johnson	43c736c2d8	Add parser finalization check for undefined symbols. svn path=/trunk/yasm/; revision=287	24 years ago
Peter Johnson	e170a2f8b3	Add symrec_get_visibility(). svn path=/trunk/yasm/; revision=286	24 years ago
Peter Johnson	6ac7d95579	Call expr_expand_equ() on effective address from bytecode_parser_finalize(). svn path=/trunk/yasm/; revision=285	24 years ago
Peter Johnson	6a7504341f	Add _copy() constructor. Add expr_expand_equ(). svn path=/trunk/yasm/; revision=284	24 years ago
Peter Johnson	0be7a0d444	Add first version of post-parsing bytecode finalization. Lots of work still to be done at the bytecode and expression level. svn path=/trunk/yasm/; revision=283	24 years ago
Peter Johnson	68c9dcc62c	Add several major functions, including effective address ModRM calculation (only 16-bit is implemented at the moment) via expr_checkea(). svn path=/trunk/yasm/; revision=282	24 years ago
Peter Johnson	a83fc9c8f6	Change order of arguments for get_ and check_ functions to better match other functions (floatnum * as first arg). svn path=/trunk/yasm/; revision=281	24 years ago
Peter Johnson	c6d051a5f2	Allow both signed and unsigned interpretations for get_int and check_size. Change argument order on get_int and check_size to better match other functions (intnum * first arg). svn path=/trunk/yasm/; revision=280	24 years ago
Peter Johnson	df1245459f	Add parsing of memory expressions. Currently adds a lot of duplication for the expressions in the yacc code, but I don't see an easier way right now. Also, no validity checking is done. svn path=/trunk/yasm/; revision=279	24 years ago
Peter Johnson	8149291eca	Add expr_contains_float() and symrec_get_equ() functions. These are the first of many functions like this which will be needed for advanced validity checking in the finalization of the parser stage. Fix yacc grammar to not use the (incorrect) expr_no_fltstr, and change memexp to memexpr and its handling to prepare for memory expressions. svn path=/trunk/yasm/; revision=278	24 years ago
Peter Johnson	053329a368	Clarify and fix some usages of valid/need flags for modrm and sib bytes. In bytecode_print(), check for NULL ea displacement and print out modrm and sib bytes in octal (because it's easier to read the 2/3/3 format in octal). svn path=/trunk/yasm/; revision=277	24 years ago
Peter Johnson	84de990744	Support TIMES prefix. Split expr parsing to have a no-float and no-string version (for times and reserve space). svn path=/trunk/yasm/; revision=275	24 years ago
Peter Johnson	57a746069d	Remove NULL return checks; BitVector uses xmalloc(), so they aren't necessary. svn path=/trunk/yasm/; revision=271	24 years ago
Peter Johnson	193392dcb6	Fix LOTS of little nits. Primary changes: - New intnum module to replace using just unsigned long (for >32 bit values). Read values using BitVector instead of strtoul(). - Brought both floatnum and intnum into expr (still need to integrate calc for floatnum). - Add traversal function to ternary tree (for use by symrec_foreach). - Change floatnum output interface from single/double/extended to byte size. - Try to make floatnum/intnum interfaces very similar. Still needs work. - Add/fix *_print functions, including interating ones for sections/bytecodes. - Fix handling of $ and $$. Both now are properly parsed and bytecode'd. - Print out all sections and symbol table in main() in preparation for work on "cleanup" functionality between parser and optimizer stages (really part of the parser stage). svn path=/trunk/yasm/; revision=270	24 years ago
Peter Johnson	2e04b1830a	Add BitVector_from_Oct() and tests for it. svn path=/trunk/yasm/; revision=268	24 years ago
Peter Johnson	6e4b87ab46	Change comment to include im_ptr in list of things that cannot be reused or changed after calling bytecode_new_insn(). svn path=/trunk/yasm/; revision=267	24 years ago
Peter Johnson	217b33802c	Make data.insn.imm within bytecode a pointer. This prevents leakage in calls to bytecode_new_insn(). svn path=/trunk/yasm/; revision=266	24 years ago
Peter Johnson	fef39125bc	Use xmalloc() instead of malloc(). svn path=/trunk/yasm/; revision=265	24 years ago
Peter Johnson	c49daeab12	Move SymStatus and SymType to symrec.c from symrec.h. They're only used internally. svn path=/trunk/yasm/; revision=264	24 years ago
