Peter Johnson	94ab1135a3	Remove $Id$ and RCSID() usage. These are useless now that we're using git.	13 years ago
Peter Johnson	de38127f1c	Fix "times" relocation handling. Previously a line such as "times 4 mov rax, [rel foobar]" would result in incorrect relocations being generated. Patch by: bird-yasm@anduin.net [#211 state:resolved]	13 years ago
Peter Johnson	1e77ce6c40	Add core TASM syntax support. Contributed by: Samuel Thibault <samuel.thibault@ens-lyon.org> It is built on top of the NASM parser and preproc, with the following notable extensions for TASM syntax: - case insensitive symbols and filenames, - support for segment and size of labels, which permits to avoid giving them on each memory dereference, - support for data reservation (i.e. e.g. "var dd ?"), - support for multiples (i.e. e.g. "var dd 1 dup 10"), - little endian string integer constants, - additional expression operators: shl, shr, and, or, low, high, - additional offset keyword, - additional fword and df, - support for doubled quotes within quotes, - support for array-like and structure-like notations: t[eax] and [var].field, - support for tasm directives: macro, rept, irp, locals, proc, struc, segment, assume. Notes: - Almost all extensions are only effective when tasm_compatible_mode is set, so we should have very reduced possible breakage. - Because the "and" keyword can be an expression operator and an instruction name, the data pseudo-instructions explicitly switch the lexer state to INSTRUCTION state to fix the ambiguity. - In gen_x86_insn.py, several instructions (namely lds and lea) now take relaxed memory sizes. The reason is that in the case of tasm, the size of the actual pointed data is passed up to there, and thus any type of data should be accepted. With all of this, loadlin can be compiled by yasm with quite reduced modifications. A new TASM-like frontend is also included. svn path=/trunk/yasm/; revision=2130	16 years ago
Peter Johnson	a958ef6df8	Merge bc-int.h into bytecode.h, removing YASM_BC_INTERNAL in the process. svn path=/trunk/yasm/; revision=1894	17 years ago
Peter Johnson	ab13bd719e	Remove YASM_LIB_INTERNAL. It never really gained us that much in terms of visibility savings, as basically everything defined it. svn path=/trunk/yasm/; revision=1893	17 years ago
Peter Johnson	469e54fa4a	Update all copyright dates. svn path=/trunk/yasm/; revision=1827	18 years ago
Peter Johnson	00473ca981	Bite the bullet and convert tabs to spaces. Previously yasm's source has been using a mix of tabs and 4 spaces to indent; this looks horrible if 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. svn path=/trunk/yasm/; revision=1825	18 years ago
Peter Johnson	a770e511c1	Move libyasm-stdint.h include out of util.h, as util.h is included from build platform files. While here, fix a few warnings by pushing uintptr_t to a few more register usages. Noticed by: rugxulo@gmail.com svn path=/trunk/yasm/; revision=1786	18 years ago
Peter Johnson	9ab89fdfe6	Take [1423] to the next logical step by supporting the general case of (sym in other section)-(sym in this section) rather than just (sym in other section)-(curpos) (e.g. sym-$). Unfortunately supporting this required precbc to be flowed down to the value_finalize functions, but it's relatively reasonable to do so, as all of the _finalize() routines have access to precbc. Reported by: Peter Tanski <peter_tanski@cox.net> svn path=/trunk/yasm/; revision=1705	18 years ago
Peter Johnson	26c808a82f	Rename linemgr.c and linemgr.h to linemap.c and linemap.h. The "manager" part of linemgr is long gone, and the current naming is a little confusing. svn path=/trunk/yasm/; revision=1701	18 years ago
Peter Johnson	827930b5a4	Have incbin search include paths (long-missing feature). svn path=/trunk/yasm/; revision=1673	18 years ago
Peter Johnson	a7b6526ea4	Get rid of calc_bc_dist_func, the only times this was used was when yasm_common_calc_bc_dist was used. Rename yasm_common_calc_bc_dist to yasm_calc_bc_dist, call it directly from the expr functions, and change higher-level callers to boolean flags of whether to calculate bc distance or not. svn path=/branches/new-optimizer/; revision=1550	19 years ago
Peter Johnson	83c0ecaaec	* coretype.h (yasm_value): Add size field (specified in bits). (yasm_value_output_func): Remove valsize and shift parameters. * bytecode.h (yasm_effaddr): Remove disp_len, replacing with need_nonzero_len. (yasm_immval): Remove len. * value.h (yasm_value_initialize): Add size parameter. (yasm_value_finalize_expr): Likewise. (yasm_value_output_basic): Remove valsize and shift parameters. Update all implementations and users for the above. * intnum.c (yasm_intnum_calc): Fix bug in shift right (was doing a logical instead of arithmetic shift). * lc3b-basic.asm, lc3b-basic.errwarn, lc3b-basic.hex: Update based on fixed warnings. svn path=/trunk/yasm/; revision=1534	19 years ago
Peter Johnson	ad54f1bf5c	* bc-int.h (yasm_bytecode_callback): Add reserve flag to indicate if the bytecode outputs just space and not data. * bytecode.pxi: Update to match. * bytecode.c (yasm_bc_tobytes): Use reserve flag instead of checking against bytecode_reserve as special case. * dwarf2-info.c, dwarf2-line.c, dwarf2-dbgfmt.c, cv-symline.c, cv-type.c, * stabs-dbgfmt.c, lc3bbc.c, x86bc.c: Update to set reserve=0. * bc-align.c, bc-insn.c, bc-reserve.c, bc-org.c, bc-incbin.c, bc-data.c, * bytecode.c: Split out bytecodes into separate files. While we're here, merge LEB128 into general data bytecode. svn path=/trunk/yasm/; revision=1532	19 years ago
