Summary of changes to "p2c" ------- -- ------- -- --- Version 1.20: * Changed VAX "type t = [byte] 0..255" not to say it can't interpret size. * Changed to use a temp var when passing a constant to a VAR parameter. * Changed to avoid initializing char arrays with string literals in pre-ANSI. * Changed to make arithmetic involving character literals more readable. * Changed to accept empty parentheses in function declarations (for Modula 2). * Made more changes for VAX and MSDOS compatibility (thanks to William Bader). * Added support for PACK and UNPACK procedures (finally!). * EMBED lines beginning with `#' are no longer indented. * EatComments no longer eats EMBED comments. * Reworded "File paramter needs associated buffers" to suggest StructFiles. * Added ability to eliminate "if false" and "if true" if ElimDeadCode = 2. * Bug fix in funcs.c:handleread/write_text: Treated case where fex is a PAC. Symptom: VAX Pascal readv/writev failed when "string" was an array of chars. * Bug fix in expr.c:makeexpr_charcast: Watch for mp->val.type == NULL case. Symptom: Reference to NULL error when referring to some CONST names. (Also fixed this bug in various other places.) * Bug fix in expr.c:eval_expr_either: Check for TK_INTEGER, not tp_integer. Symptom: Constant exprs involving +, *, etc. could not always be evaluated. * Bug fix in pexpr.c:p_factor:MK_SPECIAL case: Added "target &&" check. Symptom: Reference to NULL in VAX Pascal "open(..., ..., new)". * Bug fix in p2clib.c:my_memcpy etc.: Use n-- > 0 instead of --n >= 0. Symptom: Didn't work when size_t is an unsigned integer type. * Bug fix in p2clib.c:ipow: Changed 1<< to 1L<< (also in set functions). Symptom: Didn't work on 16-bit target machines. * Bug fix in funcs.c:handleread_text: Write %g for float, %lg for double. Symptom: Bad code for reading a "single" or "shortreal" variable. * Added to sys.p2crc/trans.h the following configuration parameter: InitPACStrings String literal in initializer can be size of array. Version 1.19: * P2c's copyright has been assigned to the Free Software Foundation. * Improved p2c to preserve Pascal type names in most cases. * Introduced "PreserveTypes" (PreserveTypes=0 makes p2c work like v1.18). * Also added "PreservePointers" (default off) and "PreserveStrings" (on). * Changed p2c.h to recognize funny ANSI-like header files in HP-UX 7.0. * Changed to handle taking the address of an argument of a promotable type. * Changed parser to accept "a * -b" without syntax errors. * Fixed a few unreachable statement warnings in the p2c sources. * Changed exit(0) to exit(EXIT_SUCCESS) in main program. * Added support for VAX C and MSDOS to p2c.h. * Bug fix in parse.c:fixblock: Call filebasetype in similartypes arg. Symptom: Pascal GET procedure sometimes crashed p2c when StructFiles=1. * Bug fix in pexpr.c:p_funcarglist: Handle stdin/stdout when StructFiles=1. Symptom: myproc(output) generated "type mismatch" warning and bad code. * Bug fix in expr.c:makeexpr_rel: Use ISCONST to guard checkconst call. Symptom: "J <= A-I-1+C" where "const C=1" put p2c into an infinite loop. * Bug fix in decl.c:setupmeaning: Consider enum consts to be global names. Symptom: Local enum consts can conflict with similar global names. * Bug fix in lex.c:push_input/pop_input: Save/restore curtokbuf/curtokcase. Symptom: Value lost when main calls defmacro after setup_lex, before parser. * Bug fix in parse.c:out_function: Don't recursively output "exported" funcs. Symptom: This occurs when an "external" decl occurs local to a function. * Bug fix in p2c.h:AGETFBUF: Removed extra "&". Symptom: Taking address of an array generated a warning on some compilers. * Bug fix in p2c.h:LONG_MAX, etc.: Fixed to cast back to signed types. Symptom: LONG_MAX had type unsigned long; "(double)(-LONG_MAX)" failed. * Bug fix in p2clib.c:P_trimname: Added trailing null to output string. Symptom: Function wouldn't always work after first call. * Added to sys.p2crc/trans.h the following configuration parameter: FixPromotedArgs Fix "&" of arguments which may be promoted. PreserveTypes Use typedef to preserve most Pascal type names. PreservePointers Use typedef specifically for pointer types. PreserveStrings Use typedef specifically for string types. SpaceCommas Use spaces after commas (default on). SpaceFuncs Use spaces after function names (default off). NoBanner Suppress "From input file..." comment at top of file. Version 1.18: * Improved indentation strategy for EMBED comments. * Allowed one-line EMBED comments: {EMBED foo();} * Made {SKIP} ... {NOSKIP} comments nestable.

Symptom: Failed to compile on Apollos. * Bug fix in parse.c:fixblock: Added "sp->stm1 &&" check for WHILE statements. Symptom: "while cond do ;" caused a reference-to-NULL error. * Bug fix in decl.c:makefakestruct: Suppressed fakestruct when importing.

Version 1.17: * Introduced "StructFile" stuff to help with more intensive file operations. * Simplified "N + 0.0" to "(double)N" instead of "N" when appropriate. * Fixed typo in sys.p2crc: "LogBreakPenalty" => "RelBreakPenalty". * Changed to avoid generating bit fields as members of a union. * Now "stringarray[i] := expr" will sprintf expr into lhs with no temp var. * Handled assignment of small packed arrays of chars into big ones. * Added to sys.p2crc/trans.h the following configuration parameters: CharConsts Assume "const c='x'" is a char, not string constant.

Symptom: On many architectures, these macros didn't work at all! NOTE: These now pack small arrays in the opposite direction (LSB first). * Bug fix in funcs.c:handleread_text: changed strread of string to use %255s.
