Author	SHA1	Message	Date
Peter Johnson	bb595a8f02	Formatting changes and starting to comment more heavily. svn path=/trunk/yasm/; revision=128	24 years ago
Peter Johnson	6232670d62	Add unary precedence to some of the expression rules. Add '+' as a unary operator. Change target to use expr instead of just explabel. svn path=/trunk/yasm/; revision=126	24 years ago
Peter Johnson	5ded7b9546	Move ..start in with ..@label. svn path=/trunk/yasm/; revision=124	24 years ago
Peter Johnson	76af86221f	Move some previously seperate identifiers into general label handlers. svn path=/trunk/yasm/; revision=123	24 years ago
Peter Johnson	fa5c9d5ea9	First attempt at supporting relative jump instructions. A few hacks, but seems to work well. A few other minor fixes/changes as well (noticed when coding). svn path=/trunk/yasm/; revision=119	24 years ago
Michael Urman	c0eb4fac3e	Better and more generalized kludge for sliding $0.\d down. svn path=/trunk/yasm/; revision=118	24 years ago
Michael Urman	c4d985f1ad	Integrate expression handling into memory address expressions. Consequently change Imm->EA, and update DebugPrintBC (fix segvs too) svn path=/trunk/yasm/; revision=117	24 years ago
Peter Johnson	bd6d5322e1	Fix and tighten down on validation regexps. Add support for 4th group parameter. svn path=/trunk/yasm/; revision=116	24 years ago
Peter Johnson	187eda1c36	Eliminate conflicts by setting associativity (and precedence too). svn path=/trunk/yasm/; revision=115	24 years ago
Michael Urman	0cb10aa577	Fixed the non-ansi attempts to pass a union member casted as the union type. svn path=/trunk/yasm/; revision=113	24 years ago
Peter Johnson	daf5c6fd03	Enable and add support for (in gen_instr.pl) short xchg AX and EAX forms. svn path=/trunk/yasm/; revision=112	24 years ago
Michael Urman	84bae30656	Long hairy integration of expression handling into the grammar. Added printing, getvalue functionality to expr.[ch] Changed immval to house an expr* instead of an unsigned long. gen_instr.pl needs to be updated for ONE cases to fix pointer compares. bison s/r conflicts still need to be handled. svn path=/trunk/yasm/; revision=109	24 years ago
Peter Johnson	273a7b3c83	Change groupdate into an array, and make everything 0-based in the output code. Bit of a kludge required in gen_instr.pl to slide the $0.\d down by one (is there a better way to do it?). svn path=/trunk/yasm/; revision=108	24 years ago
Peter Johnson	7f30800f77	Allow opsize parameters, to eliminate !onebyte16 and !onebyte32. svn path=/trunk/yasm/; revision=107	24 years ago
Michael Urman	fb3e968a29	Initial checkin of expression handling. svn path=/trunk/yasm/; revision=106	24 years ago
Peter Johnson	7ffbf9829c	#0 and #1 -> @0 and @1 (for the CPU field), to avoid warning from Perl. svn path=/trunk/yasm/; revision=102	24 years ago
Peter Johnson	1636cc2441	Backroll 1.12 and 1.13, they cause conflicts. We need to find a better way to do this. svn path=/trunk/yasm/; revision=100	24 years ago
Michael Urman	02594cb9da	Added support for spitting out multiple warnings and errors. And consequently decided that i'm probably not validating half the fields correctly. Maybe peter will fix that. Hint hint. svn path=/trunk/yasm/; revision=99	24 years ago
Michael Urman	4053f1aaae	Updated validation regexps for $0.\d fields. Removed obosolete commented "next unless ref $instr{$inst};"s svn path=/trunk/yasm/; revision=98	24 years ago
Michael Urman	769e35a524	Removed use of "our," so as not to require perl 5.6 svn path=/trunk/yasm/; revision=97	24 years ago
Michael Urman	2630eece5f	Handle grouped instructions format. svn path=/trunk/yasm/; revision=96	24 years ago
Peter Johnson	a8329fcb64	Add memref to declared types. svn path=/trunk/yasm/; revision=91	24 years ago
Peter Johnson	619381bdb9	Change mem (other sized memory reference) to cause operand size mismatch error if a size is specified. svn path=/trunk/yasm/; revision=87	24 years ago
Peter Johnson	e796094e1c	Add instruction grouping to decrease size of generated yacc code. gen_instr.pl still needs to actually implement this, so this currently breaks the build. svn path=/trunk/yasm/; revision=79	24 years ago
Peter Johnson	1a88edb466	Use bison.h instead of bison.tab.h to match changes to Makefile.am. svn path=/trunk/yasm/; revision=71	24 years ago
Peter Johnson	6b93227482	Use autoconf to determine when to include our implementation of strdup, so remove util.c and create strdup.c. Make util.h, strdup.c, and several source files use config.h defines. svn path=/trunk/yasm/; revision=61	24 years ago
Michael Urman	a6ef33c04c	Added handling of labels including: better symbol table functions calling them from yacc rather than lex a new warning for .label before normal_label locallabel_base now a symrec* instead of a strdup'd string. Still needs some more error checking (to not allow multiple copies of the same label, etc.) Also includes move to y_strdup for bison.y.in (ANSI compatibility) svn path=/trunk/yasm/; revision=51	24 years ago
Michael Urman	792bb9a471	Add error rule for all instructions. svn path=/trunk/yasm/; revision=47	24 years ago
Peter Johnson	8e49bef542	Use new interface functions in bytecode.c instead of writing values directly. svn path=/trunk/yasm/; revision=44	24 years ago
Michael Urman	a100f712c7	Added third opcode byte svn path=/trunk/yasm/; revision=41	24 years ago
Michael Urman	0fa549ffd6	more modular retrofitting svn path=/trunk/yasm/; revision=40	24 years ago
Michael Urman	f8f2a15796	Horrible hack to fold ONE, and REG_A* into more general versions of the grammar, but only if they actually exist in the set; generate normally if the more general version doesn't exist. svn path=/trunk/yasm/; revision=38	24 years ago
Peter Johnson	d6c9ff56f0	Call new error output functions after every line. Moved line_number increment into single location. Use SetEASegment() to set the segment override in memory addresses. svn path=/trunk/yasm/; revision=37	24 years ago
Peter Johnson	ae7bf9e54a	Brought @valid_regs up-to-date with bison.y.in. svn path=/trunk/yasm/; revision=34	24 years ago
Peter Johnson	c07fec8b88	Fix all shift/reduce and reduce/reduce conflicts except for those that involve REG_AL, REG_AX, and REG_EAX with immediates. Also eliminated various unused rules. Still need to figure out the proper thing to do with XCHG and AX/EAX as one of the parameters. Build still breaks because ONE is not a real token (it needs to be handled along with the AL, AX, and EAX conflicts in gen_instr.pl). svn path=/trunk/yasm/; revision=33	24 years ago
Michael Urman	d168b3bdd0	Changed structure to one hash - now order is not preserved. On the bright side, rules use the \| where appropriate. Arguments after TO rules are shifted right by 1. Aliased arguments are handled in the lexer. svn path=/trunk/yasm/; revision=32	24 years ago
Peter Johnson	8bc6949d15	Added TO and segreg. svn path=/trunk/yasm/; revision=30	24 years ago
Peter Johnson	e3fae72005	Added "TO". svn path=/trunk/yasm/; revision=29	24 years ago
Michael Urman	c6274f1170	First commit. Generates all needed sections of token.l, bison.y from instrs.dat, token.l.in, bison.y.in. Optionally can use other files, or just verify input is valid. svn path=/trunk/yasm/; revision=28	24 years ago
Michael Urman	2d86196037	Inserted /* @FOO@ */ markers for dynamic generation via gen_instr.pl. svn path=/trunk/yasm/; revision=27	24 years ago
Peter Johnson	7ae09b88b7	Implemented dynamic argument types for error and warning messages. svn path=/trunk/yasm/; revision=19	24 years ago
Peter Johnson	4c34b9b6d7	Fixed regex match for DIRECTIVE_VAL. svn path=/trunk/yasm/; revision=17	24 years ago
Peter Johnson	bc2b7f3194	Changed implementation of directives. Added some rudimentary error checking. svn path=/trunk/yasm/; revision=16	24 years ago
Peter Johnson	2ddc3208dc	Merge immediate and relative structures. svn path=/trunk/yasm/; revision=11	24 years ago
Peter Johnson	2fdefb7a66	Initial check-in. Contains hardcoded instructions that should be dynamically generated. svn path=/trunk/yasm/; revision=5	24 years ago
