248 eliminated by register optimization, but it is still left in local
249 register store/restore in/from stack block,
250 * (Remove2pcodes): after removing register, check to see if it
251 should be removed from local register store/restore in/from stack

391 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
393 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
395 * device/lib/printf_large.c: removed inline assembly for portability and
396 readability. Use printf_fast if speed or size are more important.
397 * src/pic16/gen.c: removed conditions around use of DEBUGpc
398 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
400 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
402 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
403 prevent compiler warning
405 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
407 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
408 moved to level 0 and declared as static. Also they are explicit
409 placed in access bank. This was necessery because some times they
410 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
411 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
412 optimizations. Currently only compare to unsigned char is implemented,
413 * src/pic16/gen.c: added fReturnIdx array,
414 * (struct resolvedIfx) is moved to gen.h and made public,
415 * (struct _G): added sregsAlloc and sregsAllocSet fields,
416 * (aopForSym): added an optimization to directly store in stack of
417 the operand of a SEND iCode,
418 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
419 but as registers instead (AOP_REG) using the fReturnIdx array,
420 * (pic16_freeAsmop): remove the freed register from the
422 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
424 * (pic16_popGetTempRegCond): changed function prototype, now
425 function takes also a bitVector argument v which holds the current
426 set of registers that are allocated for stack access by aopForSym,
427 registers allocated in aopForSym for accessing stack symbols are not
428 any more part of the functions usedRegs field,
429 * (genCall): some times aopOp is called for a stack variable to be
430 send, aopForSym might perform the push, if this is true make sure
431 that genCall doesn't push the variable twice by testing _G.resDirect,
432 * (genFunction): changed testing for unspecified interrupt number
433 from 256 to INTNO_UNSPEC,
434 * modified selection scheme of frame pointer generation. Previously
435 if function did use local registers a frame pointer was generated,
436 now a frame pointer is generated only if function has arguments
437 (that need PLUSW2 register access), or has stack arguments, or the
438 compiler is not instructed to omit the frame pointer,
439 * (genEndFunction): before restoring local registers that were saved
440 in the function preamble, also restore the registers that *might*
441 have been allocated for stack access,
442 * (genRet): removed some old comments,
443 * (genCmp, the active (RN's) version): added a call to the
444 pic16_genCmp_special function to perform the compare with a more
445 robust and optimized way,

1119 Adding support for replacing ljmps with sjmps in jumptables
1120 generated for switch statements. For now you need to set the
1121 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1122 Now 4 algorithms for mcs51 jumptable generation are used:
1123 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
1124 addresses loaded pc-relative for up to 112 cases and stack-pushing
1125 target addresses loaded with offset from dptr for up to 256 cases.

1155 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
1157 * added libc directory. The current version of LibC contains string
1158 functions, ctype functions and macros and some functions of the
1159 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1160 be extensively tested in the future. Standard disclaimer here.
1161 Library is not automatically build yet. But one can build it by
1162 invoking 'make' inside the libc directory.

1173 * (pic16_storeForReturn): optimized return of 0,
1174 * (genCmp): experimental code for new genCmp which uses PIC18's
1175 special compare&skip instructions. Initial tests fail some times
1176 with variables grater than 1 byte in size, so new code is disabled,
1177 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1179 * (genCast): began a fix to optimize the casting of a bit to another
1180 bit, now assigning a bitfield to another bitfield will fail, sorry,

1189 and 1 for banking instruction,
1190 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
1191 caused stop processing pCodes after a inline assembly block,
1192 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

1194 registers when it shouldn't,
1195 * src/pic16/ralloc.c (allocReg): add preliminary support for
1196 supporting a limited set of temporary registers,
1198 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4206 loaded with the linker search paths (-L arguments) and the libraries
4207 to be linked with the current source (-l arguments). Changes
4208 currently will affect only the pic16 port.
4209 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4210 include path the port specific paths and port specific libraries,
4211 * gplink command now contains the $3 argument,
4212 * src/pic16/device.h,

4229 Documenting changes from previous commits.
4230 * configure.in (version 1.56),
4231 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4232 when generating output files to configure the pic16 library,
4233 but now I've commented it out, since gputils aren't installed in the
4234 SF compile farm, so library won't compile
4236 * device/lib/Makefile.in (version 1.56): initially I've added in
4237 target 'all' the prerequestive 'model-pic16' so it compiled the
4238 pic16 library, but now I've commented it out for the same reasons
4240 * added targets 'model-pic16' and 'objects-pic16' to compile the
4242 * added target 'port-specific-objects-pic16' to handle the
4243 generated libraries and copy them into the build/ directory
4244 * added target 'clean-intermediate-pic16' to clean intermediate
4245 files into pic16 directory
4246 * in target 'installdirs' added line to create directory pic16 in

4250 added lines to copy all header files to installation path,
4251 * in target 'installdirs' added line create directory for pic16
4252 headers in the installation path

4492 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
4493 LEFT_OP (left shift)
4495 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4497 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
4498 (default behaviour).
4500 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4502 A python script to validate compiler diagnostic messages. It can be
4503 used to verify that sdcc complains about bad c source code and
4504 gives a good location of the error.
4505 * support/valdiag/Makefile,
4506 * support/valdiag/valdiag.py,
4507 * support/valdiag/tests/*
4509 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4520 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4522 * src/common.h: added ifndef/define/endif macros
4523 around the header file.
4524 Bug reported from Jesus Calvino-Fraga
4526 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
4528 * sdcc.spec: updated
4529 * device/include/Makefile.in: don't install CVS directories
4530 * device/lib/Makefile.in: added removal of CVS directories after install
4531 * doc/Makefile: fixed install, added local_icons
4532 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
4533 * src/mcs51/gen.c (genRightShift): fixed bug #870788
4534 * src/ds390/gen.c (genRightShift): fixed bug #870788
4535 * src/SDCCast.c (decorateType): fixed bug #870781
4537 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4539 PIC16 port related changes:
4540 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4541 added variable stackPos,
4543 * gen.c: genCall, assignResultValue: added support for
4544 pushing/retrieving function parameters to/from stack,
4545 genFunction,genEndFunction: setup stack frame for the
4547 genAddrOf: will be changed according to bug 863624
4549 * added files genutils.c and genutils.h which contain gen*
4550 debugged and optimised functions extracted from gen.c
4552 * glue.c: added variable 'externs' which holds extern symbols,
4553 pic16emitRegularMap: is modified to properly handle relocatable
4554 symbols under the new scheme,
4555 pic16createInterruptVect: is modified
4556 pic16printPublics: is modified to emit 'global' assembler directives,
4557 added pic16_printExterns to print extern symbols,
4558 pic16glue: initializes stack/frame pointer in the beginning of
4559 the assembly output. Temporary hack, will be corrected later,
4560 because gplink yet does not support stack and SDCC does not
4561 yet support a type of crt0.o object to create the final binary.
4563 * Removed many lines that contain 8051 legacy code.
4564 * The code is finally placed under a 'code' directive.
4565 * Added port specific options.
4567 * _process_pragma: simplified since now we do not need *special*
4568 include file to define SFR registers. But a separate header
4569 will be needed. This will be developed later.
4570 * _pic16_parseOptions: added, parses port specific options:
4571 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4572 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4573 --preplace-udata-with=
4575 * _pic16_setDefaultOptions: modified to initialize section names,
4576 but hack is temporarly out of order since it needs improvement.
4577 * _pic16_genAssemblerPreamble: configuration words are emitted by
4578 their address instead of their name. This part is incomplete and
4579 supports only the 18Fxx2 devices. Other devices will emit an error
4580 during assembly since they do not contain the same set of config
4582 * _pic16_genIVT: is modified,
4584 * pcode.c: added definitions for some hardware registers that are needed
4586 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4587 All PCI entries are updated. Now LFSR is supported.
4588 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4589 * added pic16_newpCodeOpLit2 to support instructions with
4590 two literal arguments
4591 * pic16_pCode2str: corrected code that emits assembler instructions
4592 with two literal operands and those that have an access bit modifier
4593 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4594 this fixes a bug which caused some labels to be lost, when an
4595 assembler directive was added, i.e. banksel,
4596 * pic16_FixRegisterBanking: improved logic that causes the insertion
4598 * InlineFunction: functions that are called once, are not any more
4599 inlined. This can be a port option in the future,
4601 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4603 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4604 hold the corresponding uninitialized symbols,
4605 * pic16_allocProcessorRegister: registers have explicit marked the
4607 * pic16_allocInternalRegister: registers are explicit marked as
4609 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4610 processing list, so bit registers were lost,
4613 * ralloc.h: added field 'accessBank' and original symbol operand
4614 in register definition,
4615 * removed the field isMapped from register definition,
4617 ** Several functions have been removed from various sources:
4618 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4619 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4620 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4621 pic16_assignRelocatableRegisters
4623 ** others have been introduced:
4624 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4625 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4627 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4629 * support/scripts/inc2h.pl: changed definition of BIT_AT
4630 to emit 'sbit at' instead of 'bit at'. This was a request.
4632 PIC16 port related preliminary changes:
4633 * gen.c: prefixed function popRegFromString with
4634 pic16_ and all references to it corrected
4635 * pcode.c: all pic16_pc_* hardware registers prefixed
4636 with underscore (_),
4637 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4638 * ralloc.c: newReg(): when register is REG_SFR then
4639 set address to rIdx,
4640 pic16_allocProcessorRegister(): marks register wasUsed=0
4641 pic16_writeUsedRegs(): added a call to assign processor
4642 registers via pic16_assignFixedRegisters
4644 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4646 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4647 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4648 variables in unused register banks. Also the SSEG is placed
4649 wherever there is enough space for it, and IDATA can be anywhere
4650 in internal RAM. For now compile using -Wl-Y[stack_size].
4651 The mem file is different for this option as well, since it
4652 makes no sense of talking about DSEG lenght.
4654 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4656 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4657 in certain cases, e.g. when ROM assignment, patch provided
4658 from Albert den Haan.
4660 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

4803 * src/mcs51/peephole.def,
4804 * src/ds390/peephole.def: using the atomic test and clear instruction jbc

4899 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4901 * src/SDCCast.c (decorateType): disabled a transformation I added in
4902 revision 1.188 (access to fields of a structure at an absolute address);
4903 it breaks with bitfields, extern declarations, and gcse analysis.
4904 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
4905 could be assigned through a pointer, so don't complain.
4906 * src/SDCCast.c (astErrors),
4908 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

5545 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
5546 support for standard C idiom of memory mapped variables; for
5547 example, *((xdata int*)0x1234) = 1 is now internally equivalent
5548 to xdata int at 0x1234 tempvar = 1.
5549 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
5550 provided by Akiya ISHIDA

5566 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5568 Fixed bug #621531 (const & volatile confusion in the type chain).
5569 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively

5661 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
5662 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
5663 fetching of the pointer
5664 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
5665 copied from genNearPointerSet()
5666 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
5667 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
5668 If they pop r0/r1 they must be called in the opposite order than aopOp().
5669 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
5670 (resp. --stack-auto), prepared for --xstack

5681 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
5683 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5684 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5685 type for bits was changed. It resulted in bit variables becoming
5686 global, which is not permitted in PIC 14 assembly output.
5688 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5690 * doc/sdccman.lyx: various additions and updates. Rearranged sections

5703 A few small changes that speed up the peephole optimizer.
5707 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5709 Try to make the peephole optimizer smarter by maintaining
5710 an association between the assembly source code and the
5711 iCodes that originated them. Put this information to use
5712 with a new peephole rule condition "notVolatile" so that
5713 the rules can be aggressive yet still safe.
5718 * src/mcs51/peeph.def
5720 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5724 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5725 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5726 if the left or right operand symbols have the accuse flag set.
5728 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5730 Changed the type of the result of the ! (NOT) operator to char;
5731 previously it returned the same type as the source. This allows
5732 us to eliminate all the genFloatNot functions (all of its target
5733 implementations were very buggy) since !float can use the same
5736 * src/SDCCicode.c (ast2iCode): ! returns char

5745 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5746 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5747 during interrupts. Ensure WSAVE is located at a shared bank address.
5748 2. Fixed page selection in some places
5749 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5750 the registers name strings.
5751 4. Fixed "signed / unsigned compare" compiler warnings.
5752 5. The PIC port manages its own allocation of the general purpose
5753 registers, but makes no attempt to reuse them. As a result when
5754 compiling it soon runs out of general purpose registers. Some
5755 additional code was added to the files pcode.c and device.c to walk
5756 through the function call tree and rename the registers so that they
5766 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
5767 genPlus() & genMinus() when the result is the same as left or right

5773 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5775 Made bitfield a distinct type from bit so that bitfields
5776 convert as per ANSI C and bits retain their traditional
5777 boolean style behaviour. Implemented bitfield support in
5785 * src/ds390/gen.c: bit v bitfield split
5786 * src/z80/gen.c: New support for bitfields
5787 * support/regression/tests/bitfields.c: reenabled z80,
5790 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5792 Rules 246.x, 247.x relate to bitfields, the others speed up
5793 access to xdata mapped I/O devices.
5795 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5797 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5799 Cleaned up genPackBits and genUnpackBits and added two helper
5800 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5801 for literal assignments in genPackBits (thanks to Frieder for
5807 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5809 Fixed bug #748310 (pointer to function type mishandled when the
5810 function name is omitted). Also fixed a SIGSEGV when a function
5811 attribute (reentrant, etc) is used on a non-function or on a
5812 function but misplaced before the parameter list.
5814 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
5816 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
5817 * support/Util/SDCCerr.h,
5818 * support/Util/SDCCerr.c: Added func attr misuse error msg

5839 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5841 Made the constant following the "interrupt" keyword optional. If
5842 omitted, the function will not automatically be given an entry
5843 in the interrupt vector table (similar to #pragma NOIV, but
5844 less syntacticly kludgy). The interrupt number is also now
5845 range checked. Also fixed a bug in the high order bit example

5859 * src/SDCCicode.c (operandOperation): rewritten some ops
5860 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
5861 * src/SDCCsymt.c (computeType): literals are handled the same way as any
5863 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
5864 be re-activated by defining REDUCE_LITERALS)
5865 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
5866 unsigned, but are signed by default
5867 * src/SDCCval.c (constVal): rearranged
5868 * src/SDCCval.c (valMod): preliminary fix
5869 * src/SDCCval.c (valCastLiteral): use TYPE_* types

5911 constants are unsigned; added recognition of "u" flag for unsigned
5912 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
5913 * src/SDCCval.c (valDiv, valMod): fixed signdness
5914 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
5915 signedness of modulo, left and right shift

6375 added if/endif conditional macros to remove options help
6376 messages from optionsTable when a port is not configured, added
6377 support for the PIc16 port in the ports table, when executing
6378 the compiler with no port specified on command line, a default
6379 port is selected with the new macro DEFAULT_PORT which is
6380 defined in port.h, in setDefaultOptions() linkOptions is removed
6381 from initialization assignment, since now it is a set,
6382 parseCmdLine uses setParseWithComma for linkOptions, in
6383 linkEdit() linkOptions are accessed with new function indexSet()
6384 which returns the i'th item of a set variable. See SDCCset.c, in
6385 linkEdit() when calling buildCmdLine(), added linkOptions as
6386 last argument. Now users can pass arguments to gplink via the
6387 -Wl option, main() uses pic16glue() to glue up pic16 programs

6401 gpasm complaining and test the linkage with gplink, _linkCmd and
6402 _asmCmd changed to be more gplink and gpasm friendly
6403 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6404 produced an error when parsed, peep rule 12 is added to utilize
6405 movff, but it is commented out since the pCode does not support
6406 yet a command with 2 address arguments
6408 2003-05-18 <johan AT balder>
6410 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

6437 2003-05-11 Borut Razem <borut.razem AT siol.net>
6439 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

7425 2003-01-09 Bernhard Held <bernhard AT bernhardheld.de>
7426 * src/mcs51/gen.c (genPlus): replaced "mov b,acc" by "mov b,a" Fiorenzo D. Ramaglia <fd.ramaglia AT tin.it>
7428 2003-01-07 <johan AT balder>
7430 * src/SDCCast.c (decorateType): fixed bug #600035
7432 2003-01-07 Bernhard Held <bernhard AT bernhardheld.de>
7433 * as/mcs51/lkmem.c: added several l-modifiers to printf to remove warnings

7443 2003-01-06 <johan AT balder>
7445 * src/SDCCicode.c: fixed array add
7447 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
7448 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
7449 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
7451 2003-01-04 <johan AT balder>
7453 * src/SDCCval.c (getNelements): fixed the initialized array of structures
7455 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7456 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
7458 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
7459 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
7460 * support/regression/tests/bug-524697.c: fit mem usage into 8032
7462 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
7463 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
7465 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
7466 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
7468 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
7469 * src/mcs51/main.c: removed {bindir}{sep} from aslink
7471 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7473 * in \sdcc\as\mcs51\ changed these files in order to create an
7474 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7475 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7476 following files to include the previous two files: aslink.dsp,
7477 Makefile.aslink, Makefile.bcc, and Makefile.in.
7479 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7480 .adb instead of .cdb
7482 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7484 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7485 value from option --iram-size.
7487 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7489 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7492 2002-09-18 <wiml AT hhhh.org>
7494 * SDCClrange.h: exposed setFromRange() and setToRange()
7495 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7496 packRegsForAccUse() (bug 542397)
7497 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7498 multiple times and emitting the fetch operations more than once
7499 added aopGetUsesAcc() function to allow binary operators to
7500 fetch their operands in the correct order; made genMinus() emit
7501 compact code for X = LITERAL - Y
7503 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7504 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7505 sprintf() in line 1267.
7507 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7508 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7511 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7512 Changes to aslink (All the changes are marked with 'JCF'):
7514 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7517 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7518 area BSEG. Also moves, if possible, the DATA area down into the internal
7519 ram so more space is available.
7521 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7524 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7525 not bytes. Function summary() which creates a memory usage summary
7526 file with extension .mem. Reports of overlaping stack and small stack
7527 size. If the space for the stack is less than 16 bytes aslink trows a
7530 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7531 the 8051. Option 'y' for memory summary output file.
7533 Changes to sdcc (All the changes are marked with 'JCF'):
7535 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7537 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7538 overlaying area for it (uses RegBankUsed[4]).
7540 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7541 bank zero as used by default. By default aslink locates the stack
7542 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7543 the creation of the .mem file. Delegates the allocation of data area
7544 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7545 the begining of the stack area to aslink.
7547 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7548 glue() in SDCCglue.c creates an area for it.
7550 2002-09-03 Borut Razem <borut.razem AT siol.net>
7551 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7552 sdcc/src/pic/glue.c:
7553 introduced atexit() handler for teporay files removal in case of
7554 errors, assertions, ...
7556 2002-08-29 Borut Razem <borut.razem AT siol.net>
7557 * sdcc/support/cpp2/auto-host_vc_in.h:
7558 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7559 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7560 Maybe there is a similar problem with BORLANDC? It should be checked!
7562 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7563 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7564 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7565 was not executed, and the compiler (cl) launched a warning:
7566 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7568 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7569 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7571 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7572 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7574 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7575 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7576 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7577 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7578 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7579 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7580 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7581 - added Release configuration in VS projects
7582 - review of compiler an linker options
7583 - VC .exe files are generated in bin_vc directory, not to interfere
7584 with binaries generated from other projects (cygwin, mingw, bcc ...)
7586 * sdcc/src/yacc.dsp: added
7588 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7589 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7590 and insert the version number definitions from .version
7592 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7594 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
7595 added - genarate auto-host.h using auto-host_vc_in.h as template
7598 removed from CVS, generated automatically
7600 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7601 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7603 2002-08-11 Borut Razem <borut.razem AT siol.net>
7604 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7606 2002-08-10 Borut Razem <borut.razem AT siol.net>
7607 * src/SDCCmain.c (main):
7608 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7609 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7610 The consequence was that some temporary files were not removed.
7613 unification of code in functions tempfilename() and tempfile():
7614 function tempnam() is defined in Visual Studio 6.0 and .NET
7616 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7618 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7619 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7620 - removed compiler command line option /WX: Treats all warnings as errors
7621 - update a list of source files, included into the project
7623 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7624 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7625 changed project type to Generic Project so that can be correcly converted to VS.NET project
7627 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7629 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
7631 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
7633 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7634 added return 0 statements after assert() to make compiler happy
7636 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7637 added newline in the def file to keep MSC compiler satisfied
7639 * sdcc/src/z80/gen.c:
7640 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7641 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7642 - solved MSC error in function aopDump()
7644 * sdcc_vc.h: define PREFIX as "\\sdcc"
7646 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
7647 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

7650 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
7651 - Rewrote the register banking algorithm.
7652 - Added pCode live-range analysis to registers (for now, only non-used and
7653 singly-used registers optimized away)
7655 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
7657 * 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.

7682 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
7684 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
7686 2002-03-28 Johan Knol <johan AT balder>
7688 * src/SDCCval.c: fixed bug #532436
7690 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7692 Added "char *Processor" field to the port structure.
7695 Added -p option. Allows port dependent processor to be specified.
7698 Initialized the new field char *Processor field to NULL in all ports
7701 Compiler generated registers for interrupt context saving
7702 were not getting allocated.
7704 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7707 Fixed left shift. Will promote the left side of a left shift
7708 if a) left shifting more than size of operand or b) when assigned
7709 to something size > size of left side
7711 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7713 tons of changes. Register allocation has been
7714 rewritten. Added customization for the various PICs. Flow
7715 analysis is restructured. ...
7721 Added. device.c is a PIC port hack to accomodate variations
7724 2002-03-13 Michael Hope <michaelh AT vroom>
7726 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
7728 2002-03-04 johanknol <johanknol AT manik>
7730 * /src/SDCCval.c: fixed
7732 const unsigned char arr[][2] = { { 0, 1 } };
7733 t18.c:1: error: Initializer element is not constant
7735 2002-03-04 bela <bela AT manik>
7737 * /device/include/mcs51reg.h:
7738 ds89c420 register definition update
7740 2002-03-03 <johan AT FRIJA>

7819 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
7821 * sdcc/src/SDCCloop.c:
7822 Previous fix was not good. basic blocks that have "break" or "return" are
7823 not really partof a loop , but live ranges used in these blocks should
7824 be live thru the entire loop, so set partOfLoop but don't add them to
7827 2002-02-21 <johan AT FRIJA>
7829 * src/SDCCcse.c: fixed bug #514308
7831 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
7834 Fixed BUG #519583. If a conditional block ended in a return/break
7835 statement inside a loop, it was not being considered part of the loop.
7837 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
7839 2002-02-10 Karl Bongers <karl AT turbobit.com>
7842 Fixed up SDCDB debugger somewhat. Updated debugger/README
7843 with lots of comments and notes.
7845 * device/examples/test2.c:
7846 Fix bug, "red" variable not being initialized(compiler complained).
7848 * device/examples/Makefile, examples/test3.c:
7849 Add Makefile in device/examples folder, compiles test3.c
7850 for use as a multiple module SDCDB test case.
7852 * sim/ucsim/cmd.src/cmdset.cc:
7853 Took out debug printfs in ucsim "next" command.
7856 Karl and Johan start ucsim XA support. Most dissassembly working,
7857 about 75% emulation done(plenty of work remaining).
7859 * sim/ucsim/z80.src:
7860 Add Z80 support to ucsim, add test-ucz80 regression test,
7861 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
7862 Notice z80 compiler fails on examples/test3.c/crc code.
7864 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>
7866 * src/mcs51/gen.c, src/mcs51/main.c, src/mcs51/ralloc.c:
7867 Added support for --parms-in-bank1
7869 * src/ds390/peeph.def:
7870 added a few more peephole optimzations
7873 1) added __builtin_inp & __builtin_outp used to read in data of given length
7874 from a memory mapped port
7875 2) added __builtin_memcmp
7876 3) added __builtin_swapw swap bytes of a short
7878 * src/ds390/gen.c, src/ds390/gen.h, src/ds390/ralloc.c:
7879 1) handle multiple send & receives from register bank1
7880 2) ralloc can now allocate DPTR1 to some liveRanges
7882 * src/SDCCsymt.c, src/SDCCsymt.h:
7883 changes to handle multiple sends & receives
7886 added some pointer arithmetic optimization
7889 added some pointer arithmetic optimizations but not stable yet so not
7890 called from anywhere (will get this working shortly)
7892 * src/SDCCopt.c: fixed for multiple sends & receives
7895 1) added options --parms-in-bank1 (ds390/mcs51) & --protect-sp-update
7896 2) preprocessing done AFTER port->finalizeoptions . This allows ports to
7897 set preprocessor defines (depending on options)
