254 * (Remove2pcodes): after removing register, check to see if it
255 should be removed from local register store/restore in/from stack

395 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
397 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
399 * device/lib/printf_large.c: removed inline assembly for portability and
400 readability. Use printf_fast if speed or size are more important.
401 * src/pic16/gen.c: removed conditions around use of DEBUGpc
402 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
404 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
406 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
407 prevent compiler warning
409 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
411 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
412 moved to level 0 and declared as static. Also they are explicit
413 placed in access bank. This was necessery because some times they
414 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
415 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
416 optimizations. Currently only compare to unsigned char is implemented,
417 * src/pic16/gen.c: added fReturnIdx array,
418 * (struct resolvedIfx) is moved to gen.h and made public,
419 * (struct _G): added sregsAlloc and sregsAllocSet fields,
420 * (aopForSym): added an optimization to directly store in stack of
421 the operand of a SEND iCode,
422 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
423 but as registers instead (AOP_REG) using the fReturnIdx array,
424 * (pic16_freeAsmop): remove the freed register from the
426 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
428 * (pic16_popGetTempRegCond): changed function prototype, now
429 function takes also a bitVector argument v which holds the current
430 set of registers that are allocated for stack access by aopForSym,
431 registers allocated in aopForSym for accessing stack symbols are not
432 any more part of the functions usedRegs field,
433 * (genCall): some times aopOp is called for a stack variable to be
434 send, aopForSym might perform the push, if this is true make sure
435 that genCall doesn't push the variable twice by testing _G.resDirect,
436 * (genFunction): changed testing for unspecified interrupt number
437 from 256 to INTNO_UNSPEC,
438 * modified selection scheme of frame pointer generation. Previously
439 if function did use local registers a frame pointer was generated,
440 now a frame pointer is generated only if function has arguments
441 (that need PLUSW2 register access), or has stack arguments, or the
442 compiler is not instructed to omit the frame pointer,
443 * (genEndFunction): before restoring local registers that were saved
444 in the function preamble, also restore the registers that *might*
445 have been allocated for stack access,
446 * (genRet): removed some old comments,

1123 Adding support for replacing ljmps with sjmps in jumptables
1124 generated for switch statements. For now you need to set the
1125 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1126 Now 4 algorithms for mcs51 jumptable generation are used:
1127 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
1128 addresses loaded pc-relative for up to 112 cases and stack-pushing
1129 target addresses loaded with offset from dptr for up to 256 cases.

1159 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
1161 * added libc directory. The current version of LibC contains string
1162 functions, ctype functions and macros and some functions of the
1163 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1164 be extensively tested in the future. Standard disclaimer here.
1165 Library is not automatically build yet. But one can build it by
1166 invoking 'make' inside the libc directory.

1177 * (pic16_storeForReturn): optimized return of 0,
1178 * (genCmp): experimental code for new genCmp which uses PIC18's
1179 special compare&skip instructions. Initial tests fail some times
1180 with variables grater than 1 byte in size, so new code is disabled,
1181 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1183 * (genCast): began a fix to optimize the casting of a bit to another
1184 bit, now assigning a bitfield to another bitfield will fail, sorry,

1192 * (isBankInstruction): modified to return 0 for no banking instruction,
1193 and 1 for banking instruction,
1194 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
1195 caused stop processing pCodes after a inline assembly block,
1196 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
1197 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
1198 registers when it shouldn't,
1199 * src/pic16/ralloc.c (allocReg): add preliminary support for
1200 supporting a limited set of temporary registers,
1202 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

1208 (genFunction): optimize RECEIVE iCodes in reentrant functions
1210 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1212 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

4210 loaded with the linker search paths (-L arguments) and the libraries
4211 to be linked with the current source (-l arguments). Changes
4212 currently will affect only the pic16 port.
4213 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4214 include path the port specific paths and port specific libraries,
4215 * gplink command now contains the $3 argument,
4216 * src/pic16/device.h,

4233 Documenting changes from previous commits.
4234 * configure.in (version 1.56),
4235 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4236 when generating output files to configure the pic16 library,
4237 but now I've commented it out, since gputils aren't installed in the
4238 SF compile farm, so library won't compile
4240 * device/lib/Makefile.in (version 1.56): initially I've added in
4241 target 'all' the prerequestive 'model-pic16' so it compiled the
4242 pic16 library, but now I've commented it out for the same reasons
4244 * added targets 'model-pic16' and 'objects-pic16' to compile the
4246 * added target 'port-specific-objects-pic16' to handle the
4247 generated libraries and copy them into the build/ directory
4248 * added target 'clean-intermediate-pic16' to clean intermediate
4249 files into pic16 directory
4250 * in target 'installdirs' added line to create directory pic16 in

4254 added lines to copy all header files to installation path,
4255 * in target 'installdirs' added line create directory for pic16
4256 headers in the installation path

4496 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
4497 LEFT_OP (left shift)
4499 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4501 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
4502 (default behaviour).
4504 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4506 A python script to validate compiler diagnostic messages. It can be
4507 used to verify that sdcc complains about bad c source code and
4508 gives a good location of the error.
4509 * support/valdiag/Makefile,
4510 * support/valdiag/valdiag.py,
4511 * support/valdiag/tests/*

4524 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4526 * src/common.h: added ifndef/define/endif macros
4527 around the header file.
4528 Bug reported from Jesus Calvino-Fraga
4530 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
4532 * sdcc.spec: updated
4533 * device/include/Makefile.in: don't install CVS directories
4534 * device/lib/Makefile.in: added removal of CVS directories after install
4535 * doc/Makefile: fixed install, added local_icons
4536 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
4537 * src/mcs51/gen.c (genRightShift): fixed bug #870788
4538 * src/ds390/gen.c (genRightShift): fixed bug #870788
4539 * src/SDCCast.c (decorateType): fixed bug #870781
4541 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4543 PIC16 port related changes:
4544 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4545 added variable stackPos,
4547 * gen.c: genCall, assignResultValue: added support for
4548 pushing/retrieving function parameters to/from stack,
4549 genFunction,genEndFunction: setup stack frame for the
4551 genAddrOf: will be changed according to bug 863624
4553 * added files genutils.c and genutils.h which contain gen*
4554 debugged and optimised functions extracted from gen.c
4556 * glue.c: added variable 'externs' which holds extern symbols,
4557 pic16emitRegularMap: is modified to properly handle relocatable
4558 symbols under the new scheme,
4559 pic16createInterruptVect: is modified
4560 pic16printPublics: is modified to emit 'global' assembler directives,
4561 added pic16_printExterns to print extern symbols,
4562 pic16glue: initializes stack/frame pointer in the beginning of
4563 the assembly output. Temporary hack, will be corrected later,
4564 because gplink yet does not support stack and SDCC does not
4565 yet support a type of crt0.o object to create the final binary.
4567 * Removed many lines that contain 8051 legacy code.
4568 * The code is finally placed under a 'code' directive.
4569 * Added port specific options.
4571 * _process_pragma: simplified since now we do not need *special*
4572 include file to define SFR registers. But a separate header
4573 will be needed. This will be developed later.
4574 * _pic16_parseOptions: added, parses port specific options:
4575 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4576 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4577 --preplace-udata-with=
4579 * _pic16_setDefaultOptions: modified to initialize section names,
4580 but hack is temporarly out of order since it needs improvement.
4581 * _pic16_genAssemblerPreamble: configuration words are emitted by
4582 their address instead of their name. This part is incomplete and
4583 supports only the 18Fxx2 devices. Other devices will emit an error
4584 during assembly since they do not contain the same set of config
4586 * _pic16_genIVT: is modified,
4588 * pcode.c: added definitions for some hardware registers that are needed
4590 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4591 All PCI entries are updated. Now LFSR is supported.
4592 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4593 * added pic16_newpCodeOpLit2 to support instructions with
4594 two literal arguments
4595 * pic16_pCode2str: corrected code that emits assembler instructions
4596 with two literal operands and those that have an access bit modifier
4597 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4598 this fixes a bug which caused some labels to be lost, when an
4599 assembler directive was added, i.e. banksel,
4600 * pic16_FixRegisterBanking: improved logic that causes the insertion
4602 * InlineFunction: functions that are called once, are not any more
4603 inlined. This can be a port option in the future,
4605 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4607 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4608 hold the corresponding uninitialized symbols,
4609 * pic16_allocProcessorRegister: registers have explicit marked the
4611 * pic16_allocInternalRegister: registers are explicit marked as
4613 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4614 processing list, so bit registers were lost,
4617 * ralloc.h: added field 'accessBank' and original symbol operand
4618 in register definition,
4619 * removed the field isMapped from register definition,
4621 ** Several functions have been removed from various sources:
4622 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4623 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4624 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4625 pic16_assignRelocatableRegisters
4627 ** others have been introduced:
4628 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4629 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4631 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4633 * support/scripts/inc2h.pl: changed definition of BIT_AT
4634 to emit 'sbit at' instead of 'bit at'. This was a request.
4636 PIC16 port related preliminary changes:
4637 * gen.c: prefixed function popRegFromString with
4638 pic16_ and all references to it corrected
4639 * pcode.c: all pic16_pc_* hardware registers prefixed
4640 with underscore (_),
4641 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4642 * ralloc.c: newReg(): when register is REG_SFR then
4643 set address to rIdx,
4644 pic16_allocProcessorRegister(): marks register wasUsed=0
4645 pic16_writeUsedRegs(): added a call to assign processor
4646 registers via pic16_assignFixedRegisters
4648 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4650 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4651 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4652 variables in unused register banks. Also the SSEG is placed
4653 wherever there is enough space for it, and IDATA can be anywhere
4654 in internal RAM. For now compile using -Wl-Y[stack_size].
4655 The mem file is different for this option as well, since it
4656 makes no sense of talking about DSEG lenght.
4658 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4660 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4661 in certain cases, e.g. when ROM assignment, patch provided
4662 from Albert den Haan.

4807 * src/mcs51/peephole.def,
4808 * src/ds390/peephole.def: using the atomic test and clear instruction jbc

4903 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4905 * src/SDCCast.c (decorateType): disabled a transformation I added in
4906 revision 1.188 (access to fields of a structure at an absolute address);
4907 it breaks with bitfields, extern declarations, and gcse analysis.
4908 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
4909 could be assigned through a pointer, so don't complain.
4910 * src/SDCCast.c (astErrors),
4912 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

5549 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
5550 support for standard C idiom of memory mapped variables; for
5551 example, *((xdata int*)0x1234) = 1 is now internally equivalent
5552 to xdata int at 0x1234 tempvar = 1.
5553 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
5554 provided by Akiya ISHIDA

5570 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5572 Fixed bug #621531 (const & volatile confusion in the type chain).
5573 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively

5665 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
5666 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
5667 fetching of the pointer
5668 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
5669 copied from genNearPointerSet()
5670 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
5671 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
5672 If they pop r0/r1 they must be called in the opposite order than aopOp().
5673 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
5674 (resp. --stack-auto), prepared for --xstack

5685 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
5687 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5688 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5689 type for bits was changed. It resulted in bit variables becoming
5690 global, which is not permitted in PIC 14 assembly output.
5692 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5694 * doc/sdccman.lyx: various additions and updates. Rearranged sections

5707 A few small changes that speed up the peephole optimizer.
5711 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5713 Try to make the peephole optimizer smarter by maintaining
5714 an association between the assembly source code and the
5715 iCodes that originated them. Put this information to use
5716 with a new peephole rule condition "notVolatile" so that
5717 the rules can be aggressive yet still safe.
5722 * src/mcs51/peeph.def
5724 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5728 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5729 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5730 if the left or right operand symbols have the accuse flag set.
5732 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5734 Changed the type of the result of the ! (NOT) operator to char;
5735 previously it returned the same type as the source. This allows
5736 us to eliminate all the genFloatNot functions (all of its target
5737 implementations were very buggy) since !float can use the same
5740 * src/SDCCicode.c (ast2iCode): ! returns char

5750 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5751 during interrupts. Ensure WSAVE is located at a shared bank address.
5752 2. Fixed page selection in some places
5753 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5754 the registers name strings.
5755 4. Fixed "signed / unsigned compare" compiler warnings.
5756 5. The PIC port manages its own allocation of the general purpose
5757 registers, but makes no attempt to reuse them. As a result when
5758 compiling it soon runs out of general purpose registers. Some
5759 additional code was added to the files pcode.c and device.c to walk
5760 through the function call tree and rename the registers so that they
5770 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
5771 genPlus() & genMinus() when the result is the same as left or right

5777 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5779 Made bitfield a distinct type from bit so that bitfields
5780 convert as per ANSI C and bits retain their traditional
5781 boolean style behaviour. Implemented bitfield support in
5789 * src/ds390/gen.c: bit v bitfield split
5790 * src/z80/gen.c: New support for bitfields
5791 * support/regression/tests/bitfields.c: reenabled z80,
5794 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5796 Rules 246.x, 247.x relate to bitfields, the others speed up
5797 access to xdata mapped I/O devices.
5799 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5801 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5803 Cleaned up genPackBits and genUnpackBits and added two helper
5804 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5805 for literal assignments in genPackBits (thanks to Frieder for
5811 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5813 Fixed bug #748310 (pointer to function type mishandled when the
5814 function name is omitted). Also fixed a SIGSEGV when a function
5815 attribute (reentrant, etc) is used on a non-function or on a
5816 function but misplaced before the parameter list.
5818 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
5820 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
5821 * support/Util/SDCCerr.h,

5843 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5845 Made the constant following the "interrupt" keyword optional. If
5846 omitted, the function will not automatically be given an entry
5847 in the interrupt vector table (similar to #pragma NOIV, but
5848 less syntacticly kludgy). The interrupt number is also now
5849 range checked. Also fixed a bug in the high order bit example

5865 * src/SDCCsymt.c (computeType): literals are handled the same way as any
5867 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
5868 be re-activated by defining REDUCE_LITERALS)

5870 unsigned, but are signed by default
5871 * src/SDCCval.c (constVal): rearranged
5872 * src/SDCCval.c (valMod): preliminary fix
5873 * src/SDCCval.c (valCastLiteral): use TYPE_* types

6379 added if/endif conditional macros to remove options help
6380 messages from optionsTable when a port is not configured, added
6381 support for the PIc16 port in the ports table, when executing
6382 the compiler with no port specified on command line, a default
6383 port is selected with the new macro DEFAULT_PORT which is
6384 defined in port.h, in setDefaultOptions() linkOptions is removed
6385 from initialization assignment, since now it is a set,
6386 parseCmdLine uses setParseWithComma for linkOptions, in
6387 linkEdit() linkOptions are accessed with new function indexSet()
6388 which returns the i'th item of a set variable. See SDCCset.c, in
6389 linkEdit() when calling buildCmdLine(), added linkOptions as
6390 last argument. Now users can pass arguments to gplink via the
6391 -Wl option, main() uses pic16glue() to glue up pic16 programs

6405 gpasm complaining and test the linkage with gplink, _linkCmd and
6406 _asmCmd changed to be more gplink and gpasm friendly
6407 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6408 produced an error when parsed, peep rule 12 is added to utilize
6409 movff, but it is commented out since the pCode does not support
6410 yet a command with 2 address arguments
6412 2003-05-18 <johan AT balder>
6414 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

6441 2003-05-11 Borut Razem <borut.razem AT siol.net>
6443 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

7429 2003-01-09 Bernhard Held <bernhard AT bernhardheld.de>
7430 * src/mcs51/gen.c (genPlus): replaced "mov b,acc" by "mov b,a" Fiorenzo D. Ramaglia <fd.ramaglia AT tin.it>
7432 2003-01-07 <johan AT balder>
7434 * src/SDCCast.c (decorateType): fixed bug #600035
7436 2003-01-07 Bernhard Held <bernhard AT bernhardheld.de>
7437 * as/mcs51/lkmem.c: added several l-modifiers to printf to remove warnings

7447 2003-01-06 <johan AT balder>
7449 * src/SDCCicode.c: fixed array add
7451 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
7452 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
7453 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
7455 2003-01-04 <johan AT balder>
7457 * src/SDCCval.c (getNelements): fixed the initialized array of structures
7459 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7460 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
7462 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
7463 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
7464 * support/regression/tests/bug-524697.c: fit mem usage into 8032
7466 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
7467 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
7469 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
7470 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
7472 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
7473 * src/mcs51/main.c: removed {bindir}{sep} from aslink
7475 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7477 * in \sdcc\as\mcs51\ changed these files in order to create an
7478 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7479 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7480 following files to include the previous two files: aslink.dsp,
7481 Makefile.aslink, Makefile.bcc, and Makefile.in.
7483 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7484 .adb instead of .cdb
7486 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7488 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7489 value from option --iram-size.
7491 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7493 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7496 2002-09-18 <wiml AT hhhh.org>
7498 * SDCClrange.h: exposed setFromRange() and setToRange()
7499 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7500 packRegsForAccUse() (bug 542397)
7501 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7502 multiple times and emitting the fetch operations more than once
7503 added aopGetUsesAcc() function to allow binary operators to
7504 fetch their operands in the correct order; made genMinus() emit
7505 compact code for X = LITERAL - Y
7507 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7508 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7509 sprintf() in line 1267.
7511 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7512 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7515 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7516 Changes to aslink (All the changes are marked with 'JCF'):
7518 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7521 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7522 area BSEG. Also moves, if possible, the DATA area down into the internal
7523 ram so more space is available.
7525 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7528 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7529 not bytes. Function summary() which creates a memory usage summary
7530 file with extension .mem. Reports of overlaping stack and small stack
7531 size. If the space for the stack is less than 16 bytes aslink trows a
7534 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7535 the 8051. Option 'y' for memory summary output file.
7537 Changes to sdcc (All the changes are marked with 'JCF'):
7539 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7541 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7542 overlaying area for it (uses RegBankUsed[4]).
7544 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7545 bank zero as used by default. By default aslink locates the stack
7546 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7547 the creation of the .mem file. Delegates the allocation of data area
7548 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7549 the begining of the stack area to aslink.
7551 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7552 glue() in SDCCglue.c creates an area for it.
7554 2002-09-03 Borut Razem <borut.razem AT siol.net>
7555 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7556 sdcc/src/pic/glue.c:
7557 introduced atexit() handler for teporay files removal in case of
7558 errors, assertions, ...
7560 2002-08-29 Borut Razem <borut.razem AT siol.net>
7561 * sdcc/support/cpp2/auto-host_vc_in.h:
7562 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7563 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7564 Maybe there is a similar problem with BORLANDC? It should be checked!
7566 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7567 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7568 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7569 was not executed, and the compiler (cl) launched a warning:
7570 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7572 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7573 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7575 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7576 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7578 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7579 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7580 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7581 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7582 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7583 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7584 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7585 - added Release configuration in VS projects
7586 - review of compiler an linker options
7587 - VC .exe files are generated in bin_vc directory, not to interfere
7588 with binaries generated from other projects (cygwin, mingw, bcc ...)
7590 * sdcc/src/yacc.dsp: added
7592 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7593 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7594 and insert the version number definitions from .version
7596 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7598 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
7599 added - genarate auto-host.h using auto-host_vc_in.h as template
7602 removed from CVS, generated automatically
7604 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7605 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7607 2002-08-11 Borut Razem <borut.razem AT siol.net>
7608 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7610 2002-08-10 Borut Razem <borut.razem AT siol.net>
7611 * src/SDCCmain.c (main):
7612 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7613 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7614 The consequence was that some temporary files were not removed.
7617 unification of code in functions tempfilename() and tempfile():
7618 function tempnam() is defined in Visual Studio 6.0 and .NET
7620 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7622 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7623 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7624 - removed compiler command line option /WX: Treats all warnings as errors
7625 - update a list of source files, included into the project
7627 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7628 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7629 changed project type to Generic Project so that can be correcly converted to VS.NET project
7631 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7633 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
7635 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
7637 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7638 added return 0 statements after assert() to make compiler happy
7640 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7641 added newline in the def file to keep MSC compiler satisfied
7643 * sdcc/src/z80/gen.c:
7644 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7645 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7646 - solved MSC error in function aopDump()
7648 * sdcc_vc.h: define PREFIX as "\\sdcc"
7650 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
7651 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

7654 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
7655 - Rewrote the register banking algorithm.
7656 - Added pCode live-range analysis to registers (for now, only non-used and
7657 singly-used registers optimized away)
7659 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
7661 * 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.

7686 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
7688 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
7690 2002-03-28 Johan Knol <johan AT balder>
7692 * src/SDCCval.c: fixed bug #532436
7694 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7696 Added "char *Processor" field to the port structure.
7699 Added -p option. Allows port dependent processor to be specified.
7702 Initialized the new field char *Processor field to NULL in all ports
7705 Compiler generated registers for interrupt context saving
7706 were not getting allocated.
7708 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7711 Fixed left shift. Will promote the left side of a left shift
7712 if a) left shifting more than size of operand or b) when assigned
7713 to something size > size of left side
7715 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7717 tons of changes. Register allocation has been
7718 rewritten. Added customization for the various PICs. Flow
7719 analysis is restructured. ...
7725 Added. device.c is a PIC port hack to accomodate variations
7728 2002-03-13 Michael Hope <michaelh AT vroom>
7730 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
7732 2002-03-04 johanknol <johanknol AT manik>
7734 * /src/SDCCval.c: fixed
7736 const unsigned char arr[][2] = { { 0, 1 } };
7737 t18.c:1: error: Initializer element is not constant
7739 2002-03-04 bela <bela AT manik>
7741 * /device/include/mcs51reg.h:
7742 ds89c420 register definition update
7744 2002-03-03 <johan AT FRIJA>

7823 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
7825 * sdcc/src/SDCCloop.c:
7826 Previous fix was not good. basic blocks that have "break" or "return" are
7827 not really partof a loop , but live ranges used in these blocks should
7828 be live thru the entire loop, so set partOfLoop but don't add them to
7831 2002-02-21 <johan AT FRIJA>
7833 * src/SDCCcse.c: fixed bug #514308
7835 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
7838 Fixed BUG #519583. If a conditional block ended in a return/break
7839 statement inside a loop, it was not being considered part of the loop.
7841 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
7843 2002-02-10 Karl Bongers <karl AT turbobit.com>
7846 Fixed up SDCDB debugger somewhat. Updated debugger/README
7847 with lots of comments and notes.
7849 * device/examples/test2.c:
7850 Fix bug, "red" variable not being initialized(compiler complained).
7852 * device/examples/Makefile, examples/test3.c:
7853 Add Makefile in device/examples folder, compiles test3.c
7854 for use as a multiple module SDCDB test case.
7856 * sim/ucsim/cmd.src/cmdset.cc:
7857 Took out debug printfs in ucsim "next" command.
7860 Karl and Johan start ucsim XA support. Most dissassembly working,
7861 about 75% emulation done(plenty of work remaining).
7863 * sim/ucsim/z80.src:
7864 Add Z80 support to ucsim, add test-ucz80 regression test,
7865 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
7866 Notice z80 compiler fails on examples/test3.c/crc code.
7868 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>
7870 * src/mcs51/gen.c, src/mcs51/main.c, src/mcs51/ralloc.c:
7871 Added support for --parms-in-bank1
7873 * src/ds390/peeph.def:
7874 added a few more peephole optimzations
7877 1) added __builtin_inp & __builtin_outp used to read in data of given length
7878 from a memory mapped port
7879 2) added __builtin_memcmp
7880 3) added __builtin_swapw swap bytes of a short
7882 * src/ds390/gen.c, src/ds390/gen.h, src/ds390/ralloc.c:
7883 1) handle multiple send & receives from register bank1
7884 2) ralloc can now allocate DPTR1 to some liveRanges
7886 * src/SDCCsymt.c, src/SDCCsymt.h:
7887 changes to handle multiple sends & receives
7890 added some pointer arithmetic optimization
7893 added some pointer arithmetic optimizations but not stable yet so not
7894 called from anywhere (will get this working shortly)
7896 * src/SDCCopt.c: fixed for multiple sends & receives
7899 1) added options --parms-in-bank1 (ds390/mcs51) & --protect-sp-update
7900 2) preprocessing done AFTER port->finalizeoptions . This allows ports to
7901 set preprocessor defines (depending on options)
