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

384 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
386 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
387 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
389 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
391 * device/lib/printf_large.c: removed inline assembly for portability and
392 readability. Use printf_fast if speed or size are more important.
393 * src/pic16/gen.c: removed conditions around use of DEBUGpc
394 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
396 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
398 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
399 prevent compiler warning
401 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
403 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
404 moved to level 0 and declared as static. Also they are explicit
405 placed in access bank. This was necessery because some times they
406 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
407 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
408 optimizations. Currently only compare to unsigned char is implemented,
409 * src/pic16/gen.c: added fReturnIdx array,
410 * (struct resolvedIfx) is moved to gen.h and made public,
411 * (struct _G): added sregsAlloc and sregsAllocSet fields,
412 * (aopForSym): added an optimization to directly store in stack of
413 the operand of a SEND iCode,
414 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
415 but as registers instead (AOP_REG) using the fReturnIdx array,
416 * (pic16_freeAsmop): remove the freed register from the
418 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
420 * (pic16_popGetTempRegCond): changed function prototype, now
421 function takes also a bitVector argument v which holds the current
422 set of registers that are allocated for stack access by aopForSym,
423 registers allocated in aopForSym for accessing stack symbols are not
424 any more part of the functions usedRegs field,
425 * (genCall): some times aopOp is called for a stack variable to be
426 send, aopForSym might perform the push, if this is true make sure
427 that genCall doesn't push the variable twice by testing _G.resDirect,
428 * (genFunction): changed testing for unspecified interrupt number
429 from 256 to INTNO_UNSPEC,
430 * modified selection scheme of frame pointer generation. Previously
431 if function did use local registers a frame pointer was generated,
432 now a frame pointer is generated only if function has arguments
433 (that need PLUSW2 register access), or has stack arguments, or the
434 compiler is not instructed to omit the frame pointer,
435 * (genEndFunction): before restoring local registers that were saved
436 in the function preamble, also restore the registers that *might*
437 have been allocated for stack access,
438 * (genRet): removed some old comments,
439 * (genCmp, the active (RN's) version): added a call to the
440 pic16_genCmp_special function to perform the compare with a more
441 robust and optimized way,
442 * (genInline): a feature has been added in inline code generation,
443 which allows a wildcard variable substitution when writing inline
444 assembly. Code is incomplete and experimental therefore undocumented,
445 * (genCast): changed order of aopOp for result and right to allow

1116 generated for switch statements. For now you need to set the
1117 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1118 Now 4 algorithms for mcs51 jumptable generation are used:
1119 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

1151 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
1153 * added libc directory. The current version of LibC contains string
1154 functions, ctype functions and macros and some functions of the
1155 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1156 be extensively tested in the future. Standard disclaimer here.
1157 Library is not automatically build yet. But one can build it by
1158 invoking 'make' inside the libc directory.

1169 * (pic16_storeForReturn): optimized return of 0,
1170 * (genCmp): experimental code for new genCmp which uses PIC18's
1171 special compare&skip instructions. Initial tests fail some times
1172 with variables grater than 1 byte in size, so new code is disabled,
1173 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1175 * (genCast): began a fix to optimize the casting of a bit to another
1176 bit, now assigning a bitfield to another bitfield will fail, sorry,

1185 and 1 for banking instruction,
1186 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
1187 caused stop processing pCodes after a inline assembly block,
1188 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

1190 registers when it shouldn't,
1191 * src/pic16/ralloc.c (allocReg): add preliminary support for
1192 supporting a limited set of temporary registers,
1194 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

1200 (genFunction): optimize RECEIVE iCodes in reentrant functions
1202 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4202 loaded with the linker search paths (-L arguments) and the libraries
4203 to be linked with the current source (-l arguments). Changes
4204 currently will affect only the pic16 port.
4205 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4206 include path the port specific paths and port specific libraries,
4207 * gplink command now contains the $3 argument,
4208 * src/pic16/device.h,

4225 Documenting changes from previous commits.
4226 * configure.in (version 1.56),
4227 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4228 when generating output files to configure the pic16 library,
4229 but now I've commented it out, since gputils aren't installed in the
4230 SF compile farm, so library won't compile
4232 * device/lib/Makefile.in (version 1.56): initially I've added in
4233 target 'all' the prerequestive 'model-pic16' so it compiled the
4234 pic16 library, but now I've commented it out for the same reasons
4236 * added targets 'model-pic16' and 'objects-pic16' to compile the
4238 * added target 'port-specific-objects-pic16' to handle the
4239 generated libraries and copy them into the build/ directory
4240 * added target 'clean-intermediate-pic16' to clean intermediate
4241 files into pic16 directory
4242 * in target 'installdirs' added line to create directory pic16 in

4246 added lines to copy all header files to installation path,
4247 * in target 'installdirs' added line create directory for pic16
4248 headers in the installation path

4487 * src/SDCCast.c (decorateType),
4488 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
4489 LEFT_OP (left shift)
4491 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4493 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
4494 (default behaviour).
4496 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4498 A python script to validate compiler diagnostic messages. It can be
4499 used to verify that sdcc complains about bad c source code and
4500 gives a good location of the error.
4501 * support/valdiag/Makefile,
4502 * support/valdiag/valdiag.py,
4503 * support/valdiag/tests/*

4516 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4518 * src/common.h: added ifndef/define/endif macros
4519 around the header file.
4520 Bug reported from Jesus Calvino-Fraga
4522 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
4524 * sdcc.spec: updated
4525 * device/include/Makefile.in: don't install CVS directories
4526 * device/lib/Makefile.in: added removal of CVS directories after install
4527 * doc/Makefile: fixed install, added local_icons
4528 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
4529 * src/mcs51/gen.c (genRightShift): fixed bug #870788
4530 * src/ds390/gen.c (genRightShift): fixed bug #870788
4531 * src/SDCCast.c (decorateType): fixed bug #870781
4533 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4535 PIC16 port related changes:
4536 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4537 added variable stackPos,
4539 * gen.c: genCall, assignResultValue: added support for
4540 pushing/retrieving function parameters to/from stack,
4541 genFunction,genEndFunction: setup stack frame for the
4543 genAddrOf: will be changed according to bug 863624
4545 * added files genutils.c and genutils.h which contain gen*
4546 debugged and optimised functions extracted from gen.c
4548 * glue.c: added variable 'externs' which holds extern symbols,
4549 pic16emitRegularMap: is modified to properly handle relocatable
4550 symbols under the new scheme,
4551 pic16createInterruptVect: is modified
4552 pic16printPublics: is modified to emit 'global' assembler directives,
4553 added pic16_printExterns to print extern symbols,
4554 pic16glue: initializes stack/frame pointer in the beginning of
4555 the assembly output. Temporary hack, will be corrected later,
4556 because gplink yet does not support stack and SDCC does not
4557 yet support a type of crt0.o object to create the final binary.
4559 * Removed many lines that contain 8051 legacy code.
4560 * The code is finally placed under a 'code' directive.
4561 * Added port specific options.
4563 * _process_pragma: simplified since now we do not need *special*
4564 include file to define SFR registers. But a separate header
4565 will be needed. This will be developed later.
4566 * _pic16_parseOptions: added, parses port specific options:
4567 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4568 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4569 --preplace-udata-with=
4571 * _pic16_setDefaultOptions: modified to initialize section names,
4572 but hack is temporarly out of order since it needs improvement.
4573 * _pic16_genAssemblerPreamble: configuration words are emitted by
4574 their address instead of their name. This part is incomplete and
4575 supports only the 18Fxx2 devices. Other devices will emit an error
4576 during assembly since they do not contain the same set of config
4578 * _pic16_genIVT: is modified,
4580 * pcode.c: added definitions for some hardware registers that are needed
4582 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4583 All PCI entries are updated. Now LFSR is supported.
4584 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4585 * added pic16_newpCodeOpLit2 to support instructions with
4586 two literal arguments
4587 * pic16_pCode2str: corrected code that emits assembler instructions
4588 with two literal operands and those that have an access bit modifier
4589 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4590 this fixes a bug which caused some labels to be lost, when an
4591 assembler directive was added, i.e. banksel,
4592 * pic16_FixRegisterBanking: improved logic that causes the insertion
4594 * InlineFunction: functions that are called once, are not any more
4595 inlined. This can be a port option in the future,
4597 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4599 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4600 hold the corresponding uninitialized symbols,
4601 * pic16_allocProcessorRegister: registers have explicit marked the
4603 * pic16_allocInternalRegister: registers are explicit marked as
4605 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4606 processing list, so bit registers were lost,
4609 * ralloc.h: added field 'accessBank' and original symbol operand
4610 in register definition,
4611 * removed the field isMapped from register definition,
4613 ** Several functions have been removed from various sources:
4614 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4615 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4616 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4617 pic16_assignRelocatableRegisters
4619 ** others have been introduced:
4620 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4621 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4623 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4625 * support/scripts/inc2h.pl: changed definition of BIT_AT
4626 to emit 'sbit at' instead of 'bit at'. This was a request.
4628 PIC16 port related preliminary changes:
4629 * gen.c: prefixed function popRegFromString with
4630 pic16_ and all references to it corrected
4631 * pcode.c: all pic16_pc_* hardware registers prefixed
4632 with underscore (_),
4633 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4634 * ralloc.c: newReg(): when register is REG_SFR then
4635 set address to rIdx,
4636 pic16_allocProcessorRegister(): marks register wasUsed=0
4637 pic16_writeUsedRegs(): added a call to assign processor
4638 registers via pic16_assignFixedRegisters
4640 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4642 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4643 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4644 variables in unused register banks. Also the SSEG is placed
4645 wherever there is enough space for it, and IDATA can be anywhere
4646 in internal RAM. For now compile using -Wl-Y[stack_size].
4647 The mem file is different for this option as well, since it
4648 makes no sense of talking about DSEG lenght.
4650 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4652 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4653 in certain cases, e.g. when ROM assignment, patch provided
4654 from Albert den Haan.
4656 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

4895 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4897 * src/SDCCast.c (decorateType): disabled a transformation I added in
4898 revision 1.188 (access to fields of a structure at an absolute address);
4899 it breaks with bitfields, extern declarations, and gcse analysis.
4900 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
4901 could be assigned through a pointer, so don't complain.
4902 * src/SDCCast.c (astErrors),
4904 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

5541 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
5542 support for standard C idiom of memory mapped variables; for
5543 example, *((xdata int*)0x1234) = 1 is now internally equivalent
5544 to xdata int at 0x1234 tempvar = 1.
5545 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
5546 provided by Akiya ISHIDA

5562 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5564 Fixed bug #621531 (const & volatile confusion in the type chain).
5565 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively

5657 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
5658 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
5659 fetching of the pointer
5660 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
5661 copied from genNearPointerSet()
5662 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
5663 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
5664 If they pop r0/r1 they must be called in the opposite order than aopOp().
5665 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
5666 (resp. --stack-auto), prepared for --xstack

5677 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
5679 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5680 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5681 type for bits was changed. It resulted in bit variables becoming
5682 global, which is not permitted in PIC 14 assembly output.
5684 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5686 * doc/sdccman.lyx: various additions and updates. Rearranged sections

5699 A few small changes that speed up the peephole optimizer.
5703 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5705 Try to make the peephole optimizer smarter by maintaining
5706 an association between the assembly source code and the
5707 iCodes that originated them. Put this information to use
5708 with a new peephole rule condition "notVolatile" so that
5709 the rules can be aggressive yet still safe.
5714 * src/mcs51/peeph.def
5716 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5720 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5721 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5722 if the left or right operand symbols have the accuse flag set.
5724 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5726 Changed the type of the result of the ! (NOT) operator to char;
5727 previously it returned the same type as the source. This allows
5728 us to eliminate all the genFloatNot functions (all of its target
5729 implementations were very buggy) since !float can use the same
5732 * src/SDCCicode.c (ast2iCode): ! returns char

5741 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5742 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5743 during interrupts. Ensure WSAVE is located at a shared bank address.
5744 2. Fixed page selection in some places
5745 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5746 the registers name strings.
5747 4. Fixed "signed / unsigned compare" compiler warnings.
5748 5. The PIC port manages its own allocation of the general purpose
5749 registers, but makes no attempt to reuse them. As a result when
5750 compiling it soon runs out of general purpose registers. Some
5751 additional code was added to the files pcode.c and device.c to walk
5752 through the function call tree and rename the registers so that they
5762 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
5763 genPlus() & genMinus() when the result is the same as left or right

5769 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5771 Made bitfield a distinct type from bit so that bitfields
5772 convert as per ANSI C and bits retain their traditional
5773 boolean style behaviour. Implemented bitfield support in
5781 * src/ds390/gen.c: bit v bitfield split
5782 * src/z80/gen.c: New support for bitfields
5783 * support/regression/tests/bitfields.c: reenabled z80,
5786 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5788 Rules 246.x, 247.x relate to bitfields, the others speed up
5789 access to xdata mapped I/O devices.
5791 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5793 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5795 Cleaned up genPackBits and genUnpackBits and added two helper
5796 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5797 for literal assignments in genPackBits (thanks to Frieder for
5803 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5805 Fixed bug #748310 (pointer to function type mishandled when the
5806 function name is omitted). Also fixed a SIGSEGV when a function
5807 attribute (reentrant, etc) is used on a non-function or on a
5808 function but misplaced before the parameter list.
5810 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
5812 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
5813 * support/Util/SDCCerr.h,
5814 * support/Util/SDCCerr.c: Added func attr misuse error msg

5835 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5837 Made the constant following the "interrupt" keyword optional. If
5838 omitted, the function will not automatically be given an entry
5839 in the interrupt vector table (similar to #pragma NOIV, but
5840 less syntacticly kludgy). The interrupt number is also now
5841 range checked. Also fixed a bug in the high order bit example

5855 * src/SDCCicode.c (operandOperation): rewritten some ops
5856 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
5857 * src/SDCCsymt.c (computeType): literals are handled the same way as any
5859 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
5860 be re-activated by defining REDUCE_LITERALS)
5861 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
5862 unsigned, but are signed by default
5863 * src/SDCCval.c (constVal): rearranged
5864 * src/SDCCval.c (valMod): preliminary fix
5865 * src/SDCCval.c (valCastLiteral): use TYPE_* types

5907 constants are unsigned; added recognition of "u" flag for unsigned
5908 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
5909 * src/SDCCval.c (valDiv, valMod): fixed signdness
5910 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
5911 signedness of modulo, left and right shift

6372 messages from optionsTable when a port is not configured, added
6373 support for the PIc16 port in the ports table, when executing
6374 the compiler with no port specified on command line, a default
6375 port is selected with the new macro DEFAULT_PORT which is
6376 defined in port.h, in setDefaultOptions() linkOptions is removed
6377 from initialization assignment, since now it is a set,
6378 parseCmdLine uses setParseWithComma for linkOptions, in
6379 linkEdit() linkOptions are accessed with new function indexSet()
6380 which returns the i'th item of a set variable. See SDCCset.c, in
6381 linkEdit() when calling buildCmdLine(), added linkOptions as
6382 last argument. Now users can pass arguments to gplink via the
6383 -Wl option, main() uses pic16glue() to glue up pic16 programs

6397 gpasm complaining and test the linkage with gplink, _linkCmd and
6398 _asmCmd changed to be more gplink and gpasm friendly
6399 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6400 produced an error when parsed, peep rule 12 is added to utilize
6401 movff, but it is commented out since the pCode does not support
6402 yet a command with 2 address arguments
6404 2003-05-18 <johan AT balder>
6406 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

6433 2003-05-11 Borut Razem <borut.razem AT siol.net>
6435 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

7421 2003-01-09 Bernhard Held <bernhard AT bernhardheld.de>
7422 * src/mcs51/gen.c (genPlus): replaced "mov b,acc" by "mov b,a" Fiorenzo D. Ramaglia <fd.ramaglia AT tin.it>
7424 2003-01-07 <johan AT balder>
7426 * src/SDCCast.c (decorateType): fixed bug #600035
7428 2003-01-07 Bernhard Held <bernhard AT bernhardheld.de>
7429 * as/mcs51/lkmem.c: added several l-modifiers to printf to remove warnings

7439 2003-01-06 <johan AT balder>
7441 * src/SDCCicode.c: fixed array add
7443 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
7444 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
7445 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
7447 2003-01-04 <johan AT balder>
7449 * src/SDCCval.c (getNelements): fixed the initialized array of structures
7451 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7452 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
7454 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
7455 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
7456 * support/regression/tests/bug-524697.c: fit mem usage into 8032
7458 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
7459 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
7461 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
7462 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
7464 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
7465 * src/mcs51/main.c: removed {bindir}{sep} from aslink
7467 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7469 * in \sdcc\as\mcs51\ changed these files in order to create an
7470 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7471 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7472 following files to include the previous two files: aslink.dsp,
7473 Makefile.aslink, Makefile.bcc, and Makefile.in.
7475 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7476 .adb instead of .cdb
7478 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7480 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7481 value from option --iram-size.
7483 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7485 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7488 2002-09-18 <wiml AT hhhh.org>
7490 * SDCClrange.h: exposed setFromRange() and setToRange()
7491 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7492 packRegsForAccUse() (bug 542397)
7493 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7494 multiple times and emitting the fetch operations more than once
7495 added aopGetUsesAcc() function to allow binary operators to
7496 fetch their operands in the correct order; made genMinus() emit
7497 compact code for X = LITERAL - Y
7499 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7500 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7501 sprintf() in line 1267.
7503 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7504 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7507 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7508 Changes to aslink (All the changes are marked with 'JCF'):
7510 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7513 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7514 area BSEG. Also moves, if possible, the DATA area down into the internal
7515 ram so more space is available.
7517 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7520 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7521 not bytes. Function summary() which creates a memory usage summary
7522 file with extension .mem. Reports of overlaping stack and small stack
7523 size. If the space for the stack is less than 16 bytes aslink trows a
7526 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7527 the 8051. Option 'y' for memory summary output file.
7529 Changes to sdcc (All the changes are marked with 'JCF'):
7531 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7533 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7534 overlaying area for it (uses RegBankUsed[4]).
7536 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7537 bank zero as used by default. By default aslink locates the stack
7538 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7539 the creation of the .mem file. Delegates the allocation of data area
7540 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7541 the begining of the stack area to aslink.
7543 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7544 glue() in SDCCglue.c creates an area for it.
7546 2002-09-03 Borut Razem <borut.razem AT siol.net>
7547 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7548 sdcc/src/pic/glue.c:
7549 introduced atexit() handler for teporay files removal in case of
7550 errors, assertions, ...
7552 2002-08-29 Borut Razem <borut.razem AT siol.net>
7553 * sdcc/support/cpp2/auto-host_vc_in.h:
7554 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7555 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7556 Maybe there is a similar problem with BORLANDC? It should be checked!
7558 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7559 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7560 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7561 was not executed, and the compiler (cl) launched a warning:
7562 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7564 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7565 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7567 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7568 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7570 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7571 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7572 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7573 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7574 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7575 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7576 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7577 - added Release configuration in VS projects
7578 - review of compiler an linker options
7579 - VC .exe files are generated in bin_vc directory, not to interfere
7580 with binaries generated from other projects (cygwin, mingw, bcc ...)
7582 * sdcc/src/yacc.dsp: added
7584 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7585 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7586 and insert the version number definitions from .version
7588 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7590 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
7591 added - genarate auto-host.h using auto-host_vc_in.h as template
7594 removed from CVS, generated automatically
7596 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7597 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7599 2002-08-11 Borut Razem <borut.razem AT siol.net>
7600 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7602 2002-08-10 Borut Razem <borut.razem AT siol.net>
7603 * src/SDCCmain.c (main):
7604 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7605 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7606 The consequence was that some temporary files were not removed.
7609 unification of code in functions tempfilename() and tempfile():
7610 function tempnam() is defined in Visual Studio 6.0 and .NET
7612 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7614 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7615 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7616 - removed compiler command line option /WX: Treats all warnings as errors
7617 - update a list of source files, included into the project
7619 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7620 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7621 changed project type to Generic Project so that can be correcly converted to VS.NET project
7623 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7625 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
7627 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
7629 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7630 added return 0 statements after assert() to make compiler happy
7632 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7633 added newline in the def file to keep MSC compiler satisfied
7635 * sdcc/src/z80/gen.c:
7636 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7637 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7638 - solved MSC error in function aopDump()
7640 * sdcc_vc.h: define PREFIX as "\\sdcc"
7642 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
7643 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
7645 2002-06-22 Scott Dattalo <scott AT dattalo.com>
7646 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
7647 - Rewrote the register banking algorithm.
7648 - Added pCode live-range analysis to registers (for now, only non-used and
7649 singly-used registers optimized away)
7651 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
7653 * 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.

7678 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
7680 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
7682 2002-03-28 Johan Knol <johan AT balder>
7684 * src/SDCCval.c: fixed bug #532436
7686 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7688 Added "char *Processor" field to the port structure.
7691 Added -p option. Allows port dependent processor to be specified.
7694 Initialized the new field char *Processor field to NULL in all ports
7697 Compiler generated registers for interrupt context saving
7698 were not getting allocated.
7700 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7703 Fixed left shift. Will promote the left side of a left shift
7704 if a) left shifting more than size of operand or b) when assigned
7705 to something size > size of left side
7707 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7709 tons of changes. Register allocation has been
7710 rewritten. Added customization for the various PICs. Flow
7711 analysis is restructured. ...
7717 Added. device.c is a PIC port hack to accomodate variations
7720 2002-03-13 Michael Hope <michaelh AT vroom>
7722 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
7724 2002-03-04 johanknol <johanknol AT manik>
7726 * /src/SDCCval.c: fixed
7728 const unsigned char arr[][2] = { { 0, 1 } };
7729 t18.c:1: error: Initializer element is not constant
7731 2002-03-04 bela <bela AT manik>
7733 * /device/include/mcs51reg.h:
7734 ds89c420 register definition update
7736 2002-03-03 <johan AT FRIJA>

7815 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
7817 * sdcc/src/SDCCloop.c:
7818 Previous fix was not good. basic blocks that have "break" or "return" are
7819 not really partof a loop , but live ranges used in these blocks should
7820 be live thru the entire loop, so set partOfLoop but don't add them to
7823 2002-02-21 <johan AT FRIJA>
7825 * src/SDCCcse.c: fixed bug #514308
7827 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
7830 Fixed BUG #519583. If a conditional block ended in a return/break
7831 statement inside a loop, it was not being considered part of the loop.
7833 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
7835 2002-02-10 Karl Bongers <karl AT turbobit.com>
7838 Fixed up SDCDB debugger somewhat. Updated debugger/README
7839 with lots of comments and notes.
7841 * device/examples/test2.c:
7842 Fix bug, "red" variable not being initialized(compiler complained).
7844 * device/examples/Makefile, examples/test3.c:
7845 Add Makefile in device/examples folder, compiles test3.c
7846 for use as a multiple module SDCDB test case.
7848 * sim/ucsim/cmd.src/cmdset.cc:
7849 Took out debug printfs in ucsim "next" command.
7852 Karl and Johan start ucsim XA support. Most dissassembly working,
7853 about 75% emulation done(plenty of work remaining).
7855 * sim/ucsim/z80.src:
7856 Add Z80 support to ucsim, add test-ucz80 regression test,
7857 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
7858 Notice z80 compiler fails on examples/test3.c/crc code.
7860 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>
7862 * src/mcs51/gen.c, src/mcs51/main.c, src/mcs51/ralloc.c:
7863 Added support for --parms-in-bank1
7865 * src/ds390/peeph.def:
7866 added a few more peephole optimzations
7869 1) added __builtin_inp & __builtin_outp used to read in data of given length
7870 from a memory mapped port
7871 2) added __builtin_memcmp
7872 3) added __builtin_swapw swap bytes of a short
7874 * src/ds390/gen.c, src/ds390/gen.h, src/ds390/ralloc.c:
7875 1) handle multiple send & receives from register bank1
7876 2) ralloc can now allocate DPTR1 to some liveRanges
7878 * src/SDCCsymt.c, src/SDCCsymt.h:
7879 changes to handle multiple sends & receives
7882 added some pointer arithmetic optimization
7885 added some pointer arithmetic optimizations but not stable yet so not
7886 called from anywhere (will get this working shortly)
7888 * src/SDCCopt.c: fixed for multiple sends & receives
7891 1) added options --parms-in-bank1 (ds390/mcs51) & --protect-sp-update
7892 2) preprocessing done AFTER port->finalizeoptions . This allows ports to
7893 set preprocessor defines (depending on options)
