360 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
362 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
364 * device/lib/printf_large.c: removed inline assembly for portability and
365 readability. Use printf_fast if speed or size are more important.
366 * src/pic16/gen.c: removed conditions around use of DEBUGpc
367 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
369 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
371 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
372 prevent compiler warning
374 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
376 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
377 moved to level 0 and declared as static. Also they are explicit
378 placed in access bank. This was necessery because some times they
379 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
380 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
381 optimizations. Currently only compare to unsigned char is implemented,
382 * src/pic16/gen.c: added fReturnIdx array,
383 * (struct resolvedIfx) is moved to gen.h and made public,
384 * (struct _G): added sregsAlloc and sregsAllocSet fields,
385 * (aopForSym): added an optimization to directly store in stack of
386 the operand of a SEND iCode,
387 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
388 but as registers instead (AOP_REG) using the fReturnIdx array,
389 * (pic16_freeAsmop): remove the freed register from the
391 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
393 * (pic16_popGetTempRegCond): changed function prototype, now
394 function takes also a bitVector argument v which holds the current
395 set of registers that are allocated for stack access by aopForSym,
396 registers allocated in aopForSym for accessing stack symbols are not
397 any more part of the functions usedRegs field,
398 * (genCall): some times aopOp is called for a stack variable to be
399 send, aopForSym might perform the push, if this is true make sure
400 that genCall doesn't push the variable twice by testing _G.resDirect,
401 * (genFunction): changed testing for unspecified interrupt number
402 from 256 to INTNO_UNSPEC,
403 * modified selection scheme of frame pointer generation. Previously
404 if function did use local registers a frame pointer was generated,
405 now a frame pointer is generated only if function has arguments
406 (that need PLUSW2 register access), or has stack arguments, or the
407 compiler is not instructed to omit the frame pointer,
408 * (genEndFunction): before restoring local registers that were saved
409 in the function preamble, also restore the registers that *might*
410 have been allocated for stack access,
411 * (genRet): removed some old comments,
412 * (genCmp, the active (RN's) version): added a call to the
413 pic16_genCmp_special function to perform the compare with a more
414 robust and optimized way,
415 * (genInline): a feature has been added in inline code generation,
416 which allows a wildcard variable substitution when writing inline
417 assembly. Code is incomplete and experimental therefore undocumented,
418 * (genCast): changed order of aopOp for result and right to allow
419 aopForSym to directly load the result if possible,
420 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
421 perform an optimized compare on some selected special occasions,
422 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
423 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
424 generate an IVT any more,
425 * src/pic16/main.c (pic16_optionsTable): added command line option
427 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
428 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
430 * src/pic16/NOTES: Raphael Neider added in list of active developers
431 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
432 jumptable_end to prevent bug #,
433 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
434 inCond and outCond fields,
435 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
436 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
437 turn off register spilling,
438 * (packRegsForOneUse): synced with other ports' versions although it
439 is not used currently,
440 * (pic16_packRegisters): added an optimization while reading
441 structure bitfields, some registers may be saved (malloc code is

1088 Adding support for replacing ljmps with sjmps in jumptables
1089 generated for switch statements. For now you need to set the
1090 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1091 Now 4 algorithms for mcs51 jumptable generation are used:
1092 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
1093 addresses loaded pc-relative for up to 112 cases and stack-pushing
1094 target addresses loaded with offset from dptr for up to 256 cases.

1124 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
1126 * added libc directory. The current version of LibC contains string
1127 functions, ctype functions and macros and some functions of the
1128 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1129 be extensively tested in the future. Standard disclaimer here.
1130 Library is not automatically build yet. But one can build it by
1131 invoking 'make' inside the libc directory.

1142 * (pic16_storeForReturn): optimized return of 0,
1143 * (genCmp): experimental code for new genCmp which uses PIC18's
1144 special compare&skip instructions. Initial tests fail some times
1145 with variables grater than 1 byte in size, so new code is disabled,
1146 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1148 * (genCast): began a fix to optimize the casting of a bit to another
1149 bit, now assigning a bitfield to another bitfield will fail, sorry,

1158 and 1 for banking instruction,
1159 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
1160 caused stop processing pCodes after a inline assembly block,
1161 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

1163 registers when it shouldn't,
1164 * src/pic16/ralloc.c (allocReg): add preliminary support for
1165 supporting a limited set of temporary registers,
1167 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

1173 (genFunction): optimize RECEIVE iCodes in reentrant functions
1175 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4175 loaded with the linker search paths (-L arguments) and the libraries
4176 to be linked with the current source (-l arguments). Changes
4177 currently will affect only the pic16 port.
4178 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4179 include path the port specific paths and port specific libraries,
4180 * gplink command now contains the $3 argument,

4198 Documenting changes from previous commits.
4199 * configure.in (version 1.56),
4200 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4201 when generating output files to configure the pic16 library,
4202 but now I've commented it out, since gputils aren't installed in the
4203 SF compile farm, so library won't compile
4205 * device/lib/Makefile.in (version 1.56): initially I've added in
4206 target 'all' the prerequestive 'model-pic16' so it compiled the
4207 pic16 library, but now I've commented it out for the same reasons
4209 * added targets 'model-pic16' and 'objects-pic16' to compile the
4211 * added target 'port-specific-objects-pic16' to handle the
4212 generated libraries and copy them into the build/ directory
4213 * added target 'clean-intermediate-pic16' to clean intermediate
4214 files into pic16 directory
4215 * in target 'installdirs' added line to create directory pic16 in

4480 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
4481 * src/SDCCsymt.c (newEnumType),
4483 * support/Util/SDCCerr.c,
4484 * support/Util/SDCCerr.h: fixed bug #871258 and some other unreported
4486 * support/regression/tests/enum.c: added test for enum values that
4487 require at least 2 bytes of storage.
4489 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4491 * src/common.h: added ifndef/define/endif macros
4492 around the header file.
4493 Bug reported from Jesus Calvino-Fraga
4495 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
4497 * sdcc.spec: updated
4498 * device/include/Makefile.in: don't install CVS directories
4499 * device/lib/Makefile.in: added removal of CVS directories after install
4500 * doc/Makefile: fixed install, added local_icons
4501 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
4502 * src/mcs51/gen.c (genRightShift): fixed bug #870788
4503 * src/ds390/gen.c (genRightShift): fixed bug #870788
4504 * src/SDCCast.c (decorateType): fixed bug #870781
4506 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4508 PIC16 port related changes:
4509 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4510 added variable stackPos,
4512 * gen.c: genCall, assignResultValue: added support for
4513 pushing/retrieving function parameters to/from stack,
4514 genFunction,genEndFunction: setup stack frame for the
4516 genAddrOf: will be changed according to bug 863624
4518 * added files genutils.c and genutils.h which contain gen*
4519 debugged and optimised functions extracted from gen.c
4521 * glue.c: added variable 'externs' which holds extern symbols,
4522 pic16emitRegularMap: is modified to properly handle relocatable
4523 symbols under the new scheme,
4524 pic16createInterruptVect: is modified
4525 pic16printPublics: is modified to emit 'global' assembler directives,
4526 added pic16_printExterns to print extern symbols,
4527 pic16glue: initializes stack/frame pointer in the beginning of
4528 the assembly output. Temporary hack, will be corrected later,
4529 because gplink yet does not support stack and SDCC does not
4530 yet support a type of crt0.o object to create the final binary.
4532 * Removed many lines that contain 8051 legacy code.
4533 * The code is finally placed under a 'code' directive.
4534 * Added port specific options.
4536 * _process_pragma: simplified since now we do not need *special*
4537 include file to define SFR registers. But a separate header
4538 will be needed. This will be developed later.
4539 * _pic16_parseOptions: added, parses port specific options:
4540 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4541 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4542 --preplace-udata-with=
4544 * _pic16_setDefaultOptions: modified to initialize section names,
4545 but hack is temporarly out of order since it needs improvement.
4546 * _pic16_genAssemblerPreamble: configuration words are emitted by
4547 their address instead of their name. This part is incomplete and
4548 supports only the 18Fxx2 devices. Other devices will emit an error
4549 during assembly since they do not contain the same set of config
4551 * _pic16_genIVT: is modified,
4553 * pcode.c: added definitions for some hardware registers that are needed
4555 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4556 All PCI entries are updated. Now LFSR is supported.
4557 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4558 * added pic16_newpCodeOpLit2 to support instructions with
4559 two literal arguments
4560 * pic16_pCode2str: corrected code that emits assembler instructions
4561 with two literal operands and those that have an access bit modifier
4562 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4563 this fixes a bug which caused some labels to be lost, when an
4564 assembler directive was added, i.e. banksel,
4565 * pic16_FixRegisterBanking: improved logic that causes the insertion
4567 * InlineFunction: functions that are called once, are not any more
4568 inlined. This can be a port option in the future,
4570 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4572 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4573 hold the corresponding uninitialized symbols,
4574 * pic16_allocProcessorRegister: registers have explicit marked the
4576 * pic16_allocInternalRegister: registers are explicit marked as
4578 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4579 processing list, so bit registers were lost,
4582 * ralloc.h: added field 'accessBank' and original symbol operand
4583 in register definition,
4584 * removed the field isMapped from register definition,
4586 ** Several functions have been removed from various sources:
4587 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4588 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4589 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4590 pic16_assignRelocatableRegisters
4592 ** others have been introduced:
4593 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4594 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4596 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4598 * support/scripts/inc2h.pl: changed definition of BIT_AT
4599 to emit 'sbit at' instead of 'bit at'. This was a request.
4601 PIC16 port related preliminary changes:
4602 * gen.c: prefixed function popRegFromString with
4603 pic16_ and all references to it corrected
4604 * pcode.c: all pic16_pc_* hardware registers prefixed
4605 with underscore (_),
4606 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4607 * ralloc.c: newReg(): when register is REG_SFR then
4608 set address to rIdx,
4609 pic16_allocProcessorRegister(): marks register wasUsed=0
4610 pic16_writeUsedRegs(): added a call to assign processor
4611 registers via pic16_assignFixedRegisters
4613 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4615 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4616 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4617 variables in unused register banks. Also the SSEG is placed
4618 wherever there is enough space for it, and IDATA can be anywhere
4619 in internal RAM. For now compile using -Wl-Y[stack_size].
4620 The mem file is different for this option as well, since it
4621 makes no sense of talking about DSEG lenght.
4623 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4625 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4626 in certain cases, e.g. when ROM assignment, patch provided
4627 from Albert den Haan.

4772 * src/mcs51/peephole.def,
4773 * src/ds390/peephole.def: using the atomic test and clear instruction jbc

4868 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4870 * src/SDCCast.c (decorateType): disabled a transformation I added in
4871 revision 1.188 (access to fields of a structure at an absolute address);
4872 it breaks with bitfields, extern declarations, and gcse analysis.
4873 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
4874 could be assigned through a pointer, so don't complain.
4875 * src/SDCCast.c (astErrors),
4877 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

5515 support for standard C idiom of memory mapped variables; for
5516 example, *((xdata int*)0x1234) = 1 is now internally equivalent
5517 to xdata int at 0x1234 tempvar = 1.
5518 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
5519 provided by Akiya ISHIDA

5631 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
5632 fetching of the pointer
5633 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
5634 copied from genNearPointerSet()
5635 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
5636 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

5650 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
5652 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5653 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5654 type for bits was changed. It resulted in bit variables becoming
5655 global, which is not permitted in PIC 14 assembly output.
5657 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5659 * doc/sdccman.lyx: various additions and updates. Rearranged sections

5672 A few small changes that speed up the peephole optimizer.
5676 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5678 Try to make the peephole optimizer smarter by maintaining
5679 an association between the assembly source code and the
5680 iCodes that originated them. Put this information to use
5681 with a new peephole rule condition "notVolatile" so that
5682 the rules can be aggressive yet still safe.
5687 * src/mcs51/peeph.def
5689 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5693 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5694 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5695 if the left or right operand symbols have the accuse flag set.
5697 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5699 Changed the type of the result of the ! (NOT) operator to char;
5700 previously it returned the same type as the source. This allows
5701 us to eliminate all the genFloatNot functions (all of its target
5702 implementations were very buggy) since !float can use the same

5714 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5715 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5716 during interrupts. Ensure WSAVE is located at a shared bank address.
5717 2. Fixed page selection in some places
5718 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5719 the registers name strings.
5720 4. Fixed "signed / unsigned compare" compiler warnings.
5721 5. The PIC port manages its own allocation of the general purpose
5722 registers, but makes no attempt to reuse them. As a result when
5723 compiling it soon runs out of general purpose registers. Some
5724 additional code was added to the files pcode.c and device.c to walk
5725 through the function call tree and rename the registers so that they
5735 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
5736 genPlus() & genMinus() when the result is the same as left or right

5742 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5744 Made bitfield a distinct type from bit so that bitfields
5745 convert as per ANSI C and bits retain their traditional
5746 boolean style behaviour. Implemented bitfield support in
5754 * src/ds390/gen.c: bit v bitfield split
5755 * src/z80/gen.c: New support for bitfields
5756 * support/regression/tests/bitfields.c: reenabled z80,
5759 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5761 Rules 246.x, 247.x relate to bitfields, the others speed up
5762 access to xdata mapped I/O devices.
5764 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5766 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5768 Cleaned up genPackBits and genUnpackBits and added two helper
5769 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5770 for literal assignments in genPackBits (thanks to Frieder for
5776 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5778 Fixed bug #748310 (pointer to function type mishandled when the
5779 function name is omitted). Also fixed a SIGSEGV when a function
5780 attribute (reentrant, etc) is used on a non-function or on a
5781 function but misplaced before the parameter list.
5783 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
5785 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
5786 * support/Util/SDCCerr.h,
5787 * support/Util/SDCCerr.c: Added func attr misuse error msg

5808 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5810 Made the constant following the "interrupt" keyword optional. If
5811 omitted, the function will not automatically be given an entry
5812 in the interrupt vector table (similar to #pragma NOIV, but
5813 less syntacticly kludgy). The interrupt number is also now
5814 range checked. Also fixed a bug in the high order bit example

5828 * src/SDCCicode.c (operandOperation): rewritten some ops
5829 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
5830 * src/SDCCsymt.c (computeType): literals are handled the same way as any
5832 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
5833 be re-activated by defining REDUCE_LITERALS)
5834 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
5835 unsigned, but are signed by default
5836 * src/SDCCval.c (constVal): rearranged
5837 * src/SDCCval.c (valMod): preliminary fix
5838 * src/SDCCval.c (valCastLiteral): use TYPE_* types

6344 added if/endif conditional macros to remove options help
6345 messages from optionsTable when a port is not configured, added
6346 support for the PIc16 port in the ports table, when executing
6347 the compiler with no port specified on command line, a default
6348 port is selected with the new macro DEFAULT_PORT which is
6349 defined in port.h, in setDefaultOptions() linkOptions is removed
6350 from initialization assignment, since now it is a set,
6351 parseCmdLine uses setParseWithComma for linkOptions, in
6352 linkEdit() linkOptions are accessed with new function indexSet()
6353 which returns the i'th item of a set variable. See SDCCset.c, in
6354 linkEdit() when calling buildCmdLine(), added linkOptions as
6355 last argument. Now users can pass arguments to gplink via the
6356 -Wl option, main() uses pic16glue() to glue up pic16 programs

6370 gpasm complaining and test the linkage with gplink, _linkCmd and
6371 _asmCmd changed to be more gplink and gpasm friendly
6372 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6373 produced an error when parsed, peep rule 12 is added to utilize
6374 movff, but it is commented out since the pCode does not support
6375 yet a command with 2 address arguments
6377 2003-05-18 <johan AT balder>
6379 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

6406 2003-05-11 Borut Razem <borut.razem AT siol.net>
6408 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

7408 2003-01-06 <karl AT turbobit.com>
7409 * sim/ucsim/cmd.src/command.cc: fixed so "break xram r 0x7654" works again in
7412 2003-01-06 <johan AT balder>
7414 * src/SDCCicode.c: fixed array add
7416 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
7417 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
7418 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
7420 2003-01-04 <johan AT balder>
7422 * src/SDCCval.c (getNelements): fixed the initialized array of structures
7424 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7425 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
7427 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
7428 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
7429 * support/regression/tests/bug-524697.c: fit mem usage into 8032
7431 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
7432 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
7434 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
7435 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
7437 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
7438 * src/mcs51/main.c: removed {bindir}{sep} from aslink
7440 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7442 * in \sdcc\as\mcs51\ changed these files in order to create an
7443 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7444 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7445 following files to include the previous two files: aslink.dsp,
7446 Makefile.aslink, Makefile.bcc, and Makefile.in.
7448 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7449 .adb instead of .cdb
7451 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7453 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7454 value from option --iram-size.
7456 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7458 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7461 2002-09-18 <wiml AT hhhh.org>
7463 * SDCClrange.h: exposed setFromRange() and setToRange()
7464 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7465 packRegsForAccUse() (bug 542397)
7466 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7467 multiple times and emitting the fetch operations more than once
7468 added aopGetUsesAcc() function to allow binary operators to
7469 fetch their operands in the correct order; made genMinus() emit
7470 compact code for X = LITERAL - Y
7472 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7473 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7474 sprintf() in line 1267.
7476 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7477 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7480 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7481 Changes to aslink (All the changes are marked with 'JCF'):
7483 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7486 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7487 area BSEG. Also moves, if possible, the DATA area down into the internal
7488 ram so more space is available.
7490 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7493 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7494 not bytes. Function summary() which creates a memory usage summary
7495 file with extension .mem. Reports of overlaping stack and small stack
7496 size. If the space for the stack is less than 16 bytes aslink trows a
7499 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7500 the 8051. Option 'y' for memory summary output file.
7502 Changes to sdcc (All the changes are marked with 'JCF'):
7504 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7506 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7507 overlaying area for it (uses RegBankUsed[4]).
7509 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7510 bank zero as used by default. By default aslink locates the stack
7511 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7512 the creation of the .mem file. Delegates the allocation of data area
7513 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7514 the begining of the stack area to aslink.
7516 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7517 glue() in SDCCglue.c creates an area for it.
7519 2002-09-03 Borut Razem <borut.razem AT siol.net>
7520 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7521 sdcc/src/pic/glue.c:
7522 introduced atexit() handler for teporay files removal in case of
7523 errors, assertions, ...
7525 2002-08-29 Borut Razem <borut.razem AT siol.net>
7526 * sdcc/support/cpp2/auto-host_vc_in.h:
7527 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7528 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7529 Maybe there is a similar problem with BORLANDC? It should be checked!
7531 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7532 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7533 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7534 was not executed, and the compiler (cl) launched a warning:
7535 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7537 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7538 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7540 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7541 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7543 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7544 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7545 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7546 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7547 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7548 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7549 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7550 - added Release configuration in VS projects
7551 - review of compiler an linker options
7552 - VC .exe files are generated in bin_vc directory, not to interfere
7553 with binaries generated from other projects (cygwin, mingw, bcc ...)
7555 * sdcc/src/yacc.dsp: added
7557 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7558 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7559 and insert the version number definitions from .version
7561 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7563 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
7564 added - genarate auto-host.h using auto-host_vc_in.h as template
7567 removed from CVS, generated automatically
7569 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7570 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7572 2002-08-11 Borut Razem <borut.razem AT siol.net>
7573 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7575 2002-08-10 Borut Razem <borut.razem AT siol.net>
7576 * src/SDCCmain.c (main):
7577 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7578 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7579 The consequence was that some temporary files were not removed.
7582 unification of code in functions tempfilename() and tempfile():
7583 function tempnam() is defined in Visual Studio 6.0 and .NET
7585 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7587 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7588 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7589 - removed compiler command line option /WX: Treats all warnings as errors
7590 - update a list of source files, included into the project
7592 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7593 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7594 changed project type to Generic Project so that can be correcly converted to VS.NET project
7596 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7598 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
7600 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
7602 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7603 added return 0 statements after assert() to make compiler happy
7605 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7606 added newline in the def file to keep MSC compiler satisfied
7608 * sdcc/src/z80/gen.c:
7609 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7610 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7611 - solved MSC error in function aopDump()
7613 * sdcc_vc.h: define PREFIX as "\\sdcc"
7615 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
7616 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

7619 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
7620 - Rewrote the register banking algorithm.
7621 - Added pCode live-range analysis to registers (for now, only non-used and
7622 singly-used registers optimized away)
7624 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
7626 * support/scripts/inc2h.pl Kevin L. Pauba <klpauba AT cox.net> submitted this perl script for converting MicroChip include files into SDCC Pic include files.

7655 2002-03-28 Johan Knol <johan AT balder>
7657 * src/SDCCval.c: fixed bug #532436
7659 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7661 Added "char *Processor" field to the port structure.
7664 Added -p option. Allows port dependent processor to be specified.
7667 Initialized the new field char *Processor field to NULL in all ports
7670 Compiler generated registers for interrupt context saving
7671 were not getting allocated.
7673 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7676 Fixed left shift. Will promote the left side of a left shift
7677 if a) left shifting more than size of operand or b) when assigned
7678 to something size > size of left side
7680 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7682 tons of changes. Register allocation has been
7683 rewritten. Added customization for the various PICs. Flow
7684 analysis is restructured. ...
7690 Added. device.c is a PIC port hack to accomodate variations
7693 2002-03-13 Michael Hope <michaelh AT vroom>
7695 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
7697 2002-03-04 johanknol <johanknol AT manik>

7701 const unsigned char arr[][2] = { { 0, 1 } };
7702 t18.c:1: error: Initializer element is not constant
7704 2002-03-04 bela <bela AT manik>
7706 * /device/include/mcs51reg.h:
7707 ds89c420 register definition update
7709 2002-03-03 <johan AT FRIJA>

7788 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
7790 * sdcc/src/SDCCloop.c:
7791 Previous fix was not good. basic blocks that have "break" or "return" are
7792 not really partof a loop , but live ranges used in these blocks should
7793 be live thru the entire loop, so set partOfLoop but don't add them to
7796 2002-02-21 <johan AT FRIJA>
7798 * src/SDCCcse.c: fixed bug #514308
7800 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
7803 Fixed BUG #519583. If a conditional block ended in a return/break
7804 statement inside a loop, it was not being considered part of the loop.
7806 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
7808 2002-02-10 Karl Bongers <karl AT turbobit.com>
7811 Fixed up SDCDB debugger somewhat. Updated debugger/README
7812 with lots of comments and notes.
7814 * device/examples/test2.c:
7815 Fix bug, "red" variable not being initialized(compiler complained).
7817 * device/examples/Makefile, examples/test3.c:
7818 Add Makefile in device/examples folder, compiles test3.c
7819 for use as a multiple module SDCDB test case.
7821 * sim/ucsim/cmd.src/cmdset.cc:
7822 Took out debug printfs in ucsim "next" command.
7825 Karl and Johan start ucsim XA support. Most dissassembly working,
7826 about 75% emulation done(plenty of work remaining).
7828 * sim/ucsim/z80.src:
7829 Add Z80 support to ucsim, add test-ucz80 regression test,
7830 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
7831 Notice z80 compiler fails on examples/test3.c/crc code.

7849 2) ralloc can now allocate DPTR1 to some liveRanges
7851 * src/SDCCsymt.c, src/SDCCsymt.h:
7852 changes to handle multiple sends & receives
7855 added some pointer arithmetic optimization
7858 added some pointer arithmetic optimizations but not stable yet so not
7859 called from anywhere (will get this working shortly)
7861 * src/SDCCopt.c: fixed for multiple sends & receives
7864 1) added options --parms-in-bank1 (ds390/mcs51) & --protect-sp-update
7865 2) preprocessing done AFTER port->finalizeoptions . This allows ports to
7866 set preprocessor defines (depending on options)
7868 * src/SDCCicode.c, src/SDCCicode.h:
7869 changes made to handle multiple sends & receives
7872 Added options --protect-sp-update (ds390) and --parms-in-bank1 (ds390/mcs51)
