403 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
405 * device/lib/printf_large.c: removed inline assembly for portability and
406 readability. Use printf_fast if speed or size are more important.
407 * src/pic16/gen.c: removed conditions around use of DEBUGpc
408 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
410 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
412 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
413 prevent compiler warning
415 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
417 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
418 moved to level 0 and declared as static. Also they are explicit
419 placed in access bank. This was necessery because some times they
420 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
421 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
422 optimizations. Currently only compare to unsigned char is implemented,
423 * src/pic16/gen.c: added fReturnIdx array,
424 * (struct resolvedIfx) is moved to gen.h and made public,
425 * (struct _G): added sregsAlloc and sregsAllocSet fields,
426 * (aopForSym): added an optimization to directly store in stack of
427 the operand of a SEND iCode,
428 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
429 but as registers instead (AOP_REG) using the fReturnIdx array,
430 * (pic16_freeAsmop): remove the freed register from the
432 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
434 * (pic16_popGetTempRegCond): changed function prototype, now
435 function takes also a bitVector argument v which holds the current
436 set of registers that are allocated for stack access by aopForSym,
437 registers allocated in aopForSym for accessing stack symbols are not
438 any more part of the functions usedRegs field,
439 * (genCall): some times aopOp is called for a stack variable to be
440 send, aopForSym might perform the push, if this is true make sure
441 that genCall doesn't push the variable twice by testing _G.resDirect,
442 * (genFunction): changed testing for unspecified interrupt number
443 from 256 to INTNO_UNSPEC,
444 * modified selection scheme of frame pointer generation. Previously
445 if function did use local registers a frame pointer was generated,
446 now a frame pointer is generated only if function has arguments
447 (that need PLUSW2 register access), or has stack arguments, or the
448 compiler is not instructed to omit the frame pointer,
449 * (genEndFunction): before restoring local registers that were saved
450 in the function preamble, also restore the registers that *might*
451 have been allocated for stack access,
452 * (genRet): removed some old comments,
453 * (genCmp, the active (RN's) version): added a call to the
454 pic16_genCmp_special function to perform the compare with a more
455 robust and optimized way,
456 * (genInline): a feature has been added in inline code generation,
457 which allows a wildcard variable substitution when writing inline
458 assembly. Code is incomplete and experimental therefore undocumented,
459 * (genCast): changed order of aopOp for result and right to allow
460 aopForSym to directly load the result if possible,
461 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
462 perform an optimized compare on some selected special occasions,

475 inCond and outCond fields,
476 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
477 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to

480 is not used currently,
481 * (pic16_packRegisters): added an optimization while reading
482 structure bitfields, some registers may be saved (malloc code is
483 decreased by 80 bytes)
485 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
487 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
488 left is a bitfield, if yes, then don't optimize assignment. Perhaps
489 this can be optimized more?

1130 generated for switch statements. For now you need to set the
1131 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1132 Now 4 algorithms for mcs51 jumptable generation are used:
1133 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

1167 * added libc directory. The current version of LibC contains string
1168 functions, ctype functions and macros and some functions of the
1169 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1170 be extensively tested in the future. Standard disclaimer here.
1171 Library is not automatically build yet. But one can build it by

1183 * (pic16_storeForReturn): optimized return of 0,
1184 * (genCmp): experimental code for new genCmp which uses PIC18's
1185 special compare&skip instructions. Initial tests fail some times
1186 with variables grater than 1 byte in size, so new code is disabled,
1187 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1189 * (genCast): began a fix to optimize the casting of a bit to another
1190 bit, now assigning a bitfield to another bitfield will fail, sorry,

1205 * src/pic16/ralloc.c (allocReg): add preliminary support for
1206 supporting a limited set of temporary registers,

4216 loaded with the linker search paths (-L arguments) and the libraries
4217 to be linked with the current source (-l arguments). Changes
4218 currently will affect only the pic16 port.
4219 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4220 include path the port specific paths and port specific libraries,
4221 * gplink command now contains the $3 argument,
4222 * src/pic16/device.h,

4239 Documenting changes from previous commits.
4240 * configure.in (version 1.56),
4241 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4242 when generating output files to configure the pic16 library,
4243 but now I've commented it out, since gputils aren't installed in the
4244 SF compile farm, so library won't compile
4246 * device/lib/Makefile.in (version 1.56): initially I've added in
4247 target 'all' the prerequestive 'model-pic16' so it compiled the
4248 pic16 library, but now I've commented it out for the same reasons
4250 * added targets 'model-pic16' and 'objects-pic16' to compile the
4252 * added target 'port-specific-objects-pic16' to handle the
4253 generated libraries and copy them into the build/ directory
4254 * added target 'clean-intermediate-pic16' to clean intermediate
4255 files into pic16 directory
4256 * in target 'installdirs' added line to create directory pic16 in

4260 added lines to copy all header files to installation path,
4261 * in target 'installdirs' added line create directory for pic16
4262 headers in the installation path

4502 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
4503 LEFT_OP (left shift)
4505 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4507 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
4508 (default behaviour).
4510 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4512 A python script to validate compiler diagnostic messages. It can be
4513 used to verify that sdcc complains about bad c source code and
4514 gives a good location of the error.
4515 * support/valdiag/Makefile,
4516 * support/valdiag/valdiag.py,
4517 * support/valdiag/tests/*
4519 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4534 Bug reported from Jesus Calvino-Fraga
4536 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
4538 * sdcc.spec: updated
4539 * device/include/Makefile.in: don't install CVS directories
4540 * device/lib/Makefile.in: added removal of CVS directories after install
4541 * doc/Makefile: fixed install, added local_icons
4542 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
4543 * src/mcs51/gen.c (genRightShift): fixed bug #870788
4544 * src/ds390/gen.c (genRightShift): fixed bug #870788

4547 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4549 PIC16 port related changes:
4550 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4551 added variable stackPos,
4553 * gen.c: genCall, assignResultValue: added support for
4554 pushing/retrieving function parameters to/from stack,
4555 genFunction,genEndFunction: setup stack frame for the
4557 genAddrOf: will be changed according to bug 863624
4559 * added files genutils.c and genutils.h which contain gen*
4560 debugged and optimised functions extracted from gen.c
4562 * glue.c: added variable 'externs' which holds extern symbols,
4563 pic16emitRegularMap: is modified to properly handle relocatable
4564 symbols under the new scheme,
4565 pic16createInterruptVect: is modified
4566 pic16printPublics: is modified to emit 'global' assembler directives,
4567 added pic16_printExterns to print extern symbols,
4568 pic16glue: initializes stack/frame pointer in the beginning of
4569 the assembly output. Temporary hack, will be corrected later,
4570 because gplink yet does not support stack and SDCC does not
4571 yet support a type of crt0.o object to create the final binary.
4573 * Removed many lines that contain 8051 legacy code.
4574 * The code is finally placed under a 'code' directive.
4575 * Added port specific options.
4577 * _process_pragma: simplified since now we do not need *special*
4578 include file to define SFR registers. But a separate header
4579 will be needed. This will be developed later.
4580 * _pic16_parseOptions: added, parses port specific options:
4581 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4582 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4583 --preplace-udata-with=
4585 * _pic16_setDefaultOptions: modified to initialize section names,
4586 but hack is temporarly out of order since it needs improvement.
4587 * _pic16_genAssemblerPreamble: configuration words are emitted by
4588 their address instead of their name. This part is incomplete and
4589 supports only the 18Fxx2 devices. Other devices will emit an error
4590 during assembly since they do not contain the same set of config
4592 * _pic16_genIVT: is modified,
4594 * pcode.c: added definitions for some hardware registers that are needed
4596 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4597 All PCI entries are updated. Now LFSR is supported.
4598 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4599 * added pic16_newpCodeOpLit2 to support instructions with
4600 two literal arguments
4601 * pic16_pCode2str: corrected code that emits assembler instructions
4602 with two literal operands and those that have an access bit modifier
4603 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4604 this fixes a bug which caused some labels to be lost, when an
4605 assembler directive was added, i.e. banksel,
4606 * pic16_FixRegisterBanking: improved logic that causes the insertion
4608 * InlineFunction: functions that are called once, are not any more
4609 inlined. This can be a port option in the future,
4611 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4613 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4614 hold the corresponding uninitialized symbols,
4615 * pic16_allocProcessorRegister: registers have explicit marked the
4617 * pic16_allocInternalRegister: registers are explicit marked as
4619 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4620 processing list, so bit registers were lost,
4623 * ralloc.h: added field 'accessBank' and original symbol operand
4624 in register definition,
4625 * removed the field isMapped from register definition,
4627 ** Several functions have been removed from various sources:
4628 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4629 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4630 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4631 pic16_assignRelocatableRegisters
4633 ** others have been introduced:
4634 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4635 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4637 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4639 * support/scripts/inc2h.pl: changed definition of BIT_AT
4640 to emit 'sbit at' instead of 'bit at'. This was a request.
4642 PIC16 port related preliminary changes:
4643 * gen.c: prefixed function popRegFromString with
4644 pic16_ and all references to it corrected
4645 * pcode.c: all pic16_pc_* hardware registers prefixed
4646 with underscore (_),
4647 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4648 * ralloc.c: newReg(): when register is REG_SFR then
4649 set address to rIdx,
4650 pic16_allocProcessorRegister(): marks register wasUsed=0
4651 pic16_writeUsedRegs(): added a call to assign processor
4652 registers via pic16_assignFixedRegisters
4654 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4656 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4657 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4658 variables in unused register banks. Also the SSEG is placed
4659 wherever there is enough space for it, and IDATA can be anywhere
4660 in internal RAM. For now compile using -Wl-Y[stack_size].
4661 The mem file is different for this option as well, since it
4662 makes no sense of talking about DSEG lenght.
4664 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4666 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4667 in certain cases, e.g. when ROM assignment, patch provided
4668 from Albert den Haan.
4670 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

4909 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4911 * src/SDCCast.c (decorateType): disabled a transformation I added in
4912 revision 1.188 (access to fields of a structure at an absolute address);
4913 it breaks with bitfields, extern declarations, and gcse analysis.
4914 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
4915 could be assigned through a pointer, so don't complain.
4916 * src/SDCCast.c (astErrors),
4918 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

4926 pre-processor macro, i.e. -DMCU=p18f452
4927 * src/pic16/ralloc.c: renamed packRegisters to pic16_packRegisters,
4928 and modified to handle 'cast' icode similarly to '=' icode

5555 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
5556 support for standard C idiom of memory mapped variables; for
5557 example, *((xdata int*)0x1234) = 1 is now internally equivalent
5558 to xdata int at 0x1234 tempvar = 1.
5559 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
5560 provided by Akiya ISHIDA

5671 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
5672 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
5673 fetching of the pointer
5674 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
5675 copied from genNearPointerSet()
5676 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
5677 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
5678 If they pop r0/r1 they must be called in the opposite order than aopOp().
5679 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
5680 (resp. --stack-auto), prepared for --xstack

5693 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5694 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5695 type for bits was changed. It resulted in bit variables becoming
5696 global, which is not permitted in PIC 14 assembly output.
5698 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5700 * doc/sdccman.lyx: various additions and updates. Rearranged sections

5713 A few small changes that speed up the peephole optimizer.
5717 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5719 Try to make the peephole optimizer smarter by maintaining
5720 an association between the assembly source code and the
5721 iCodes that originated them. Put this information to use
5722 with a new peephole rule condition "notVolatile" so that
5723 the rules can be aggressive yet still safe.
5728 * src/mcs51/peeph.def
5730 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5734 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5735 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5736 if the left or right operand symbols have the accuse flag set.
5738 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5740 Changed the type of the result of the ! (NOT) operator to char;
5741 previously it returned the same type as the source. This allows
5742 us to eliminate all the genFloatNot functions (all of its target
5743 implementations were very buggy) since !float can use the same

5756 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5757 during interrupts. Ensure WSAVE is located at a shared bank address.
5758 2. Fixed page selection in some places
5759 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5760 the registers name strings.
5761 4. Fixed "signed / unsigned compare" compiler warnings.
5762 5. The PIC port manages its own allocation of the general purpose
5763 registers, but makes no attempt to reuse them. As a result when
5764 compiling it soon runs out of general purpose registers. Some
5765 additional code was added to the files pcode.c and device.c to walk
5766 through the function call tree and rename the registers so that they
5776 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

5783 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5785 Made bitfield a distinct type from bit so that bitfields
5786 convert as per ANSI C and bits retain their traditional
5787 boolean style behaviour. Implemented bitfield support in
5795 * src/ds390/gen.c: bit v bitfield split
5796 * src/z80/gen.c: New support for bitfields
5797 * support/regression/tests/bitfields.c: reenabled z80,
5800 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5802 Rules 246.x, 247.x relate to bitfields, the others speed up
5803 access to xdata mapped I/O devices.
5805 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5807 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5809 Cleaned up genPackBits and genUnpackBits and added two helper
5810 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5811 for literal assignments in genPackBits (thanks to Frieder for
5817 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5819 Fixed bug #748310 (pointer to function type mishandled when the
5820 function name is omitted). Also fixed a SIGSEGV when a function
5821 attribute (reentrant, etc) is used on a non-function or on a
5822 function but misplaced before the parameter list.
5824 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
5826 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
5827 * support/Util/SDCCerr.h,

5849 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5851 Made the constant following the "interrupt" keyword optional. If
5852 omitted, the function will not automatically be given an entry
5853 in the interrupt vector table (similar to #pragma NOIV, but
5854 less syntacticly kludgy). The interrupt number is also now
5855 range checked. Also fixed a bug in the high order bit example

5871 * src/SDCCsymt.c (computeType): literals are handled the same way as any
5873 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
5874 be re-activated by defining REDUCE_LITERALS)

5921 constants are unsigned; added recognition of "u" flag for unsigned
5922 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
5923 * src/SDCCval.c (valDiv, valMod): fixed signdness
5924 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed

6386 messages from optionsTable when a port is not configured, added
6387 support for the PIc16 port in the ports table, when executing
6388 the compiler with no port specified on command line, a default
6389 port is selected with the new macro DEFAULT_PORT which is
6390 defined in port.h, in setDefaultOptions() linkOptions is removed
6391 from initialization assignment, since now it is a set,
6392 parseCmdLine uses setParseWithComma for linkOptions, in
6393 linkEdit() linkOptions are accessed with new function indexSet()
6394 which returns the i'th item of a set variable. See SDCCset.c, in
6395 linkEdit() when calling buildCmdLine(), added linkOptions as
6396 last argument. Now users can pass arguments to gplink via the
6397 -Wl option, main() uses pic16glue() to glue up pic16 programs

6411 gpasm complaining and test the linkage with gplink, _linkCmd and
6412 _asmCmd changed to be more gplink and gpasm friendly
6413 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6414 produced an error when parsed, peep rule 12 is added to utilize
6415 movff, but it is commented out since the pCode does not support
6416 yet a command with 2 address arguments
6418 2003-05-18 <johan AT balder>

7453 2003-01-06 <johan AT balder>
7455 * src/SDCCicode.c: fixed array add
7457 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
7458 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
7459 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
7461 2003-01-04 <johan AT balder>
7463 * src/SDCCval.c (getNelements): fixed the initialized array of structures
7465 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7466 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
7468 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
7469 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

7478 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
7479 * src/mcs51/main.c: removed {bindir}{sep} from aslink
7481 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7483 * in \sdcc\as\mcs51\ changed these files in order to create an
7484 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7485 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7486 following files to include the previous two files: aslink.dsp,
7487 Makefile.aslink, Makefile.bcc, and Makefile.in.
7489 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7490 .adb instead of .cdb
7492 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7494 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7495 value from option --iram-size.
7497 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7499 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7502 2002-09-18 <wiml AT hhhh.org>
7504 * SDCClrange.h: exposed setFromRange() and setToRange()
7505 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7506 packRegsForAccUse() (bug 542397)
7507 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7508 multiple times and emitting the fetch operations more than once
7509 added aopGetUsesAcc() function to allow binary operators to
7510 fetch their operands in the correct order; made genMinus() emit
7511 compact code for X = LITERAL - Y
7513 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7514 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7515 sprintf() in line 1267.
7517 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7518 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7521 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7522 Changes to aslink (All the changes are marked with 'JCF'):
7524 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7527 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7528 area BSEG. Also moves, if possible, the DATA area down into the internal
7529 ram so more space is available.
7531 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7534 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7535 not bytes. Function summary() which creates a memory usage summary
7536 file with extension .mem. Reports of overlaping stack and small stack
7537 size. If the space for the stack is less than 16 bytes aslink trows a
7540 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7541 the 8051. Option 'y' for memory summary output file.
7543 Changes to sdcc (All the changes are marked with 'JCF'):
7545 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7547 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7548 overlaying area for it (uses RegBankUsed[4]).
7550 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7551 bank zero as used by default. By default aslink locates the stack
7552 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7553 the creation of the .mem file. Delegates the allocation of data area
7554 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7555 the begining of the stack area to aslink.
7557 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7558 glue() in SDCCglue.c creates an area for it.
7560 2002-09-03 Borut Razem <borut.razem AT siol.net>
7561 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7562 sdcc/src/pic/glue.c:
7563 introduced atexit() handler for teporay files removal in case of
7564 errors, assertions, ...
7566 2002-08-29 Borut Razem <borut.razem AT siol.net>
7567 * sdcc/support/cpp2/auto-host_vc_in.h:
7568 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7569 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7570 Maybe there is a similar problem with BORLANDC? It should be checked!
7572 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7573 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7574 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7575 was not executed, and the compiler (cl) launched a warning:
7576 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7578 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7579 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7581 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7582 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7584 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7585 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7586 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7587 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7588 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7589 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7590 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7591 - added Release configuration in VS projects
7592 - review of compiler an linker options
7593 - VC .exe files are generated in bin_vc directory, not to interfere
7594 with binaries generated from other projects (cygwin, mingw, bcc ...)
7596 * sdcc/src/yacc.dsp: added
7598 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7599 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7600 and insert the version number definitions from .version
7602 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7604 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
7605 added - genarate auto-host.h using auto-host_vc_in.h as template
7608 removed from CVS, generated automatically
7610 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7611 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7613 2002-08-11 Borut Razem <borut.razem AT siol.net>
7614 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7616 2002-08-10 Borut Razem <borut.razem AT siol.net>
7617 * src/SDCCmain.c (main):
7618 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7619 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7620 The consequence was that some temporary files were not removed.
7623 unification of code in functions tempfilename() and tempfile():
7624 function tempnam() is defined in Visual Studio 6.0 and .NET
7626 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7628 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7629 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7630 - removed compiler command line option /WX: Treats all warnings as errors
7631 - update a list of source files, included into the project
7633 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7634 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7635 changed project type to Generic Project so that can be correcly converted to VS.NET project
7637 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7639 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
7641 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
7643 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7644 added return 0 statements after assert() to make compiler happy
7646 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7647 added newline in the def file to keep MSC compiler satisfied
7649 * sdcc/src/z80/gen.c:
7650 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7651 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7652 - solved MSC error in function aopDump()
7654 * sdcc_vc.h: define PREFIX as "\\sdcc"
7656 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
7657 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
7659 2002-06-22 Scott Dattalo <scott AT dattalo.com>
7660 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
7661 - Rewrote the register banking algorithm.
7662 - Added pCode live-range analysis to registers (for now, only non-used and
7663 singly-used registers optimized away)
7665 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
7667 * 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.

7694 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
7696 2002-03-28 Johan Knol <johan AT balder>
7698 * src/SDCCval.c: fixed bug #532436
7700 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7702 Added "char *Processor" field to the port structure.
7705 Added -p option. Allows port dependent processor to be specified.
7708 Initialized the new field char *Processor field to NULL in all ports
7711 Compiler generated registers for interrupt context saving
7712 were not getting allocated.
7714 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7717 Fixed left shift. Will promote the left side of a left shift
7718 if a) left shifting more than size of operand or b) when assigned
7719 to something size > size of left side
7721 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7723 tons of changes. Register allocation has been
7724 rewritten. Added customization for the various PICs. Flow
7725 analysis is restructured. ...
7731 Added. device.c is a PIC port hack to accomodate variations
7734 2002-03-13 Michael Hope <michaelh AT vroom>
7736 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
7738 2002-03-04 johanknol <johanknol AT manik>
7740 * /src/SDCCval.c: fixed
7742 const unsigned char arr[][2] = { { 0, 1 } };
7743 t18.c:1: error: Initializer element is not constant
7745 2002-03-04 bela <bela AT manik>
7747 * /device/include/mcs51reg.h:
7748 ds89c420 register definition update
7750 2002-03-03 <johan AT FRIJA>

7829 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
7831 * sdcc/src/SDCCloop.c:
7832 Previous fix was not good. basic blocks that have "break" or "return" are
7833 not really partof a loop , but live ranges used in these blocks should
7834 be live thru the entire loop, so set partOfLoop but don't add them to
7837 2002-02-21 <johan AT FRIJA>
7839 * src/SDCCcse.c: fixed bug #514308
7841 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
7844 Fixed BUG #519583. If a conditional block ended in a return/break
7845 statement inside a loop, it was not being considered part of the loop.
7847 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
7849 2002-02-10 Karl Bongers <karl AT turbobit.com>
7852 Fixed up SDCDB debugger somewhat. Updated debugger/README
7853 with lots of comments and notes.
7855 * device/examples/test2.c:
7856 Fix bug, "red" variable not being initialized(compiler complained).
7858 * device/examples/Makefile, examples/test3.c:
7859 Add Makefile in device/examples folder, compiles test3.c
7860 for use as a multiple module SDCDB test case.
7862 * sim/ucsim/cmd.src/cmdset.cc:
7863 Took out debug printfs in ucsim "next" command.
7866 Karl and Johan start ucsim XA support. Most dissassembly working,
7867 about 75% emulation done(plenty of work remaining).
7869 * sim/ucsim/z80.src:
7870 Add Z80 support to ucsim, add test-ucz80 regression test,
7871 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
7872 Notice z80 compiler fails on examples/test3.c/crc code.
7874 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>
7876 * src/mcs51/gen.c, src/mcs51/main.c, src/mcs51/ralloc.c:
7877 Added support for --parms-in-bank1
7879 * src/ds390/peeph.def:
7880 added a few more peephole optimzations
7883 1) added __builtin_inp & __builtin_outp used to read in data of given length
7884 from a memory mapped port
