638 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
640 Enabled VPATH feature: changed nearly all Makefiles (149 files).
641 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
643 One basic decision: e.g. src/clean.mk includes further files. In order
644 to make this work there are two solutions:
645 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
646 run configure on them. This way they can use
647 'include $(srcdir)/port-clean.mk'
648 - always include clean.mk by the Makefile at the same level. To avoid
649 that `make clean` tries to include and build Makefile.dep the
650 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
651 implemented, because now even `make uninstall` doesn't create
652 Makefile.in. clean.mk could be eliminated by pasting it in
655 * debugger/mcs51/Makefile.in: build own objects from library sources
656 (SLIB, SDCC) in current directory
658 * configure, configure.in: renamed --disable-device-lib-build in
659 --disable-device-lib; added --enable-doc, the required tools are
660 searched by configure; added result message; the toolchain for the
661 belonging ports are now only built, if the port is enabled.
663 * support/regression/*: all output is written in directory gen, because
664 the fwk and ports directories don't livet in the build tree using vpath
666 * doc/sdccman.lyx: renamed --disable-device-lib-build to
667 --disable-device-lib, added --enable-doc, added section VPATH
669 * sim/ucsim/configure.in,
670 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
671 z80 are enabled by default
673 2006-04-24 Raphael Neider <rneider AT web.de>
675 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
676 to config word, "pic14_"-prefixed some extern functions
677 (pic14_emitConfigWord): emit __config directive(s) if assignment to
678 config word has been found
679 * src/pic/device.h: added prototypes
680 * src/pic/pcode.c: added "pic14_"-prefix where needed
681 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
683 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
685 (pic14emitRegularMap): ignore config words,
686 (pic14createInterruptVect): moved generating __config directives away

697 fixes #1469504 and #1474602,
698 (pCodeRegOptimizeRegUsage): fixed typo in comment

956 archive with gcc 4.1 on mips and wrote the patch"
958 2006-03-16 Raphael Neider <rneider AT web.de>
960 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
961 the left operand is shorter than the result (c* = lit-c* + int),
963 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
966 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
968 * src/.version: increased version number to 2.5.5
969 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
970 linking is done manually in pic16 port's _linkEdit,
971 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
972 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
973 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
974 allocate asmop as AOP_ACC,
975 (aopForRemat): added parameter 'bool result' in function declaration,
976 (pic16_aopGet): return AOP_ACC when accessing WREG,

988 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
989 call to allocReg, not by manually allocating a new one,
990 (pic16_assignRegisters): now before going through the register
991 allocating functions mark all registers as free. This eliminates some
992 side effects resulting from peephole parser done earlier in the backbone

1052 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1053 which dumps before the function entry point a data byte which represents
1054 the number of the local variables used by the specified function, added
1055 'xinst' for initial support for Extended Instruction Support,
1056 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1057 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1058 port->fun_prefix anymore (may change later),
1059 (genFunction, genEndFunction): do not store/restore local registers for
1060 _main (this should take care the --main-return command line option in
1062 (genOr): removed some legacy pic-port instructions,
1063 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1064 performing operations with SFR's causes data to be written more than
1065 once to each SFR. Perhaps SFRs should be handled in special cases...
1066 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1068 * src/pic16/main.c (_process_pragma): stack bound checking did not take

1071 --extended or -y for Extended Instruction Support,
1072 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1073 (deassignLRs): *** perhaps the most important change, old 'for' code
1074 (commented out for reference), didn't account for some registers which
1075 were left marked 'not free' after a pointer operation. The change
1076 reduces register usage a lot in some cases

3434 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
3436 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3438 * device/lib/printf_large.c: removed inline assembly for portability and
3439 readability. Use printf_fast if speed or size are more important.
3440 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3441 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3443 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3445 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3446 prevent compiler warning
3448 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3450 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3451 moved to level 0 and declared as static. Also they are explicit
3452 placed in access bank. This was necessery because some times they
3453 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3454 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3455 optimizations. Currently only compare to unsigned char is implemented,
3456 * src/pic16/gen.c: added fReturnIdx array,
3457 * (struct resolvedIfx) is moved to gen.h and made public,
3458 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3459 * (aopForSym): added an optimization to directly store in stack of
3460 the operand of a SEND iCode,
3461 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3462 but as registers instead (AOP_REG) using the fReturnIdx array,
3463 * (pic16_freeAsmop): remove the freed register from the
3464 _G.sregsAlloc field,
3465 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3466 a compare of 'WREG',
3467 * (pic16_popGetTempRegCond): changed function prototype, now
3468 function takes also a bitVector argument v which holds the current
3469 set of registers that are allocated for stack access by aopForSym,
3470 registers allocated in aopForSym for accessing stack symbols are not
3471 any more part of the functions usedRegs field,
3472 * (genCall): some times aopOp is called for a stack variable to be
3473 send, aopForSym might perform the push, if this is true make sure
3474 that genCall doesn't push the variable twice by testing _G.resDirect,
3475 * (genFunction): changed testing for unspecified interrupt number
3476 from 256 to INTNO_UNSPEC,
3477 * modified selection scheme of frame pointer generation. Previously
3478 if function did use local registers a frame pointer was generated,
3479 now a frame pointer is generated only if function has arguments
3480 (that need PLUSW2 register access), or has stack arguments, or the
3481 compiler is not instructed to omit the frame pointer,
3482 * (genEndFunction): before restoring local registers that were saved
3483 in the function preamble, also restore the registers that *might*
3484 have been allocated for stack access,
3485 * (genRet): removed some old comments,

3487 pic16_genCmp_special function to perform the compare with a more
3488 robust and optimized way,
3489 * (genInline): a feature has been added in inline code generation,
3490 which allows a wildcard variable substitution when writing inline
3491 assembly. Code is incomplete and experimental therefore undocumented,
3492 * (genCast): changed order of aopOp for result and right to allow
3493 aopForSym to directly load the result if possible,

4162 Adding support for replacing ljmps with sjmps in jumptables
4163 generated for switch statements. For now you need to set the
4164 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4165 Now 4 algorithms for mcs51 jumptable generation are used:
4166 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4167 addresses loaded pc-relative for up to 112 cases and stack-pushing
4168 target addresses loaded with offset from dptr for up to 256 cases.

4198 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4200 * added libc directory. The current version of LibC contains string
4201 functions, ctype functions and macros and some functions of the
4202 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4203 be extensively tested in the future. Standard disclaimer here.
4204 Library is not automatically build yet. But one can build it by
4205 invoking 'make' inside the libc directory.

4216 * (pic16_storeForReturn): optimized return of 0,
4217 * (genCmp): experimental code for new genCmp which uses PIC18's
4218 special compare&skip instructions. Initial tests fail some times
4219 with variables grater than 1 byte in size, so new code is disabled,
4220 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4222 * (genCast): began a fix to optimize the casting of a bit to another
4223 bit, now assigning a bitfield to another bitfield will fail, sorry,

4232 and 1 for banking instruction,
4233 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4234 caused stop processing pCodes after a inline assembly block,
4235 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

4237 registers when it shouldn't,
4238 * src/pic16/ralloc.c (allocReg): add preliminary support for
4239 supporting a limited set of temporary registers,
4241 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4247 (genFunction): optimize RECEIVE iCodes in reentrant functions
4249 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7249 loaded with the linker search paths (-L arguments) and the libraries
7250 to be linked with the current source (-l arguments). Changes
7251 currently will affect only the pic16 port.
7252 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7253 include path the port specific paths and port specific libraries,
7254 * gplink command now contains the $3 argument,
7255 * src/pic16/device.h,

7272 Documenting changes from previous commits.
7273 * configure.in (version 1.56),
7274 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7275 when generating output files to configure the pic16 library,
7276 but now I've commented it out, since gputils aren't installed in the
7277 SF compile farm, so library won't compile
7279 * device/lib/Makefile.in (version 1.56): initially I've added in
7280 target 'all' the prerequestive 'model-pic16' so it compiled the
7281 pic16 library, but now I've commented it out for the same reasons
7283 * added targets 'model-pic16' and 'objects-pic16' to compile the
7285 * added target 'port-specific-objects-pic16' to handle the
7286 generated libraries and copy them into the build/ directory
7287 * added target 'clean-intermediate-pic16' to clean intermediate
7288 files into pic16 directory
7289 * in target 'installdirs' added line to create directory pic16 in

7535 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
7536 LEFT_OP (left shift)
7538 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7540 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7541 (default behaviour).
7543 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7545 A python script to validate compiler diagnostic messages. It can be
7546 used to verify that sdcc complains about bad c source code and
7547 gives a good location of the error.
7548 * support/valdiag/Makefile,
7549 * support/valdiag/valdiag.py,
7550 * support/valdiag/tests/*

7567 Bug reported from Jesus Calvino-Fraga
7569 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7571 * sdcc.spec: updated
7572 * device/include/Makefile.in: don't install CVS directories
7573 * device/lib/Makefile.in: added removal of CVS directories after install
7574 * doc/Makefile: fixed install, added local_icons
7575 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7576 * src/mcs51/gen.c (genRightShift): fixed bug #870788

7580 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7582 PIC16 port related changes:
7583 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7584 added variable stackPos,
7586 * gen.c: genCall, assignResultValue: added support for
7587 pushing/retrieving function parameters to/from stack,
7588 genFunction,genEndFunction: setup stack frame for the
7590 genAddrOf: will be changed according to bug 863624
7592 * added files genutils.c and genutils.h which contain gen*
7593 debugged and optimised functions extracted from gen.c
7595 * glue.c: added variable 'externs' which holds extern symbols,
7596 pic16emitRegularMap: is modified to properly handle relocatable
7597 symbols under the new scheme,
7598 pic16createInterruptVect: is modified
7599 pic16printPublics: is modified to emit 'global' assembler directives,
7600 added pic16_printExterns to print extern symbols,
7601 pic16glue: initializes stack/frame pointer in the beginning of
7602 the assembly output. Temporary hack, will be corrected later,
7603 because gplink yet does not support stack and SDCC does not
7604 yet support a type of crt0.o object to create the final binary.
7606 * Removed many lines that contain 8051 legacy code.
7607 * The code is finally placed under a 'code' directive.
7608 * Added port specific options.
7610 * _process_pragma: simplified since now we do not need *special*
7611 include file to define SFR registers. But a separate header
7612 will be needed. This will be developed later.
7613 * _pic16_parseOptions: added, parses port specific options:
7614 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7615 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7616 --preplace-udata-with=
7618 * _pic16_setDefaultOptions: modified to initialize section names,
7619 but hack is temporarly out of order since it needs improvement.
7620 * _pic16_genAssemblerPreamble: configuration words are emitted by
7621 their address instead of their name. This part is incomplete and
7622 supports only the 18Fxx2 devices. Other devices will emit an error
7623 during assembly since they do not contain the same set of config
7625 * _pic16_genIVT: is modified,
7627 * pcode.c: added definitions for some hardware registers that are needed
7629 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7630 All PCI entries are updated. Now LFSR is supported.
7631 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7632 * added pic16_newpCodeOpLit2 to support instructions with
7633 two literal arguments
7634 * pic16_pCode2str: corrected code that emits assembler instructions
7635 with two literal operands and those that have an access bit modifier
7636 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7637 this fixes a bug which caused some labels to be lost, when an
7638 assembler directive was added, i.e. banksel,
7639 * pic16_FixRegisterBanking: improved logic that causes the insertion
7641 * InlineFunction: functions that are called once, are not any more
7642 inlined. This can be a port option in the future,
7644 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7646 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7647 hold the corresponding uninitialized symbols,
7648 * pic16_allocProcessorRegister: registers have explicit marked the
7650 * pic16_allocInternalRegister: registers are explicit marked as
7652 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7653 processing list, so bit registers were lost,
7656 * ralloc.h: added field 'accessBank' and original symbol operand
7657 in register definition,
7658 * removed the field isMapped from register definition,
7660 ** Several functions have been removed from various sources:
7661 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7662 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7663 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7664 pic16_assignRelocatableRegisters
7666 ** others have been introduced:
7667 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7668 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7670 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7672 * support/scripts/inc2h.pl: changed definition of BIT_AT
7673 to emit 'sbit at' instead of 'bit at'. This was a request.
7675 PIC16 port related preliminary changes:
7676 * gen.c: prefixed function popRegFromString with
7677 pic16_ and all references to it corrected
7678 * pcode.c: all pic16_pc_* hardware registers prefixed
7679 with underscore (_),
7680 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7681 * ralloc.c: newReg(): when register is REG_SFR then
7682 set address to rIdx,
7683 pic16_allocProcessorRegister(): marks register wasUsed=0
7684 pic16_writeUsedRegs(): added a call to assign processor
7685 registers via pic16_assignFixedRegisters
7687 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7689 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7690 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7691 variables in unused register banks. Also the SSEG is placed
7692 wherever there is enough space for it, and IDATA can be anywhere
7693 in internal RAM. For now compile using -Wl-Y[stack_size].
7694 The mem file is different for this option as well, since it
7695 makes no sense of talking about DSEG lenght.
7697 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7699 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7700 in certain cases, e.g. when ROM assignment, patch provided
7701 from Albert den Haan.

7942 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7944 * src/SDCCast.c (decorateType): disabled a transformation I added in
7945 revision 1.188 (access to fields of a structure at an absolute address);
7946 it breaks with bitfields, extern declarations, and gcse analysis.
7947 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
7948 could be assigned through a pointer, so don't complain.
7949 * src/SDCCast.c (astErrors),
7951 * src/SDCCglue.c (emitRegularMap): fixed bug #847813
7953 2003-11-26 Vangelis Rokas <vrokas AT otenet.gr>

8705 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
8706 fetching of the pointer
8707 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8708 copied from genNearPointerSet()
8709 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8710 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
8711 If they pop r0/r1 they must be called in the opposite order than aopOp().
8712 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
8713 (resp. --stack-auto), prepared for --xstack

8724 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
8726 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8727 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8728 type for bits was changed. It resulted in bit variables becoming
8729 global, which is not permitted in PIC 14 assembly output.
8731 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8733 * doc/sdccman.lyx: various additions and updates. Rearranged sections

8746 A few small changes that speed up the peephole optimizer.
8750 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8752 Try to make the peephole optimizer smarter by maintaining
8753 an association between the assembly source code and the
8754 iCodes that originated them. Put this information to use
8755 with a new peephole rule condition "notVolatile" so that
8756 the rules can be aggressive yet still safe.
8761 * src/mcs51/peeph.def
8763 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8767 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8768 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8769 if the left or right operand symbols have the accuse flag set.
8771 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8773 Changed the type of the result of the ! (NOT) operator to char;
8774 previously it returned the same type as the source. This allows
8775 us to eliminate all the genFloatNot functions (all of its target
8776 implementations were very buggy) since !float can use the same
8779 * src/SDCCicode.c (ast2iCode): ! returns char

8788 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8789 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8790 during interrupts. Ensure WSAVE is located at a shared bank address.
8791 2. Fixed page selection in some places
8792 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8793 the registers name strings.
8794 4. Fixed "signed / unsigned compare" compiler warnings.
8795 5. The PIC port manages its own allocation of the general purpose
8796 registers, but makes no attempt to reuse them. As a result when
8797 compiling it soon runs out of general purpose registers. Some
8798 additional code was added to the files pcode.c and device.c to walk
8799 through the function call tree and rename the registers so that they
8809 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8810 genPlus() & genMinus() when the result is the same as left or right
8812 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8816 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8818 Made bitfield a distinct type from bit so that bitfields
8819 convert as per ANSI C and bits retain their traditional
8820 boolean style behaviour. Implemented bitfield support in
8828 * src/ds390/gen.c: bit v bitfield split
8829 * src/z80/gen.c: New support for bitfields
8830 * support/regression/tests/bitfields.c: reenabled z80,
8833 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8835 Rules 246.x, 247.x relate to bitfields, the others speed up
8836 access to xdata mapped I/O devices.
8838 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8840 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8842 Cleaned up genPackBits and genUnpackBits and added two helper
8843 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8844 for literal assignments in genPackBits (thanks to Frieder for
8850 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8852 Fixed bug #748310 (pointer to function type mishandled when the
8853 function name is omitted). Also fixed a SIGSEGV when a function
8854 attribute (reentrant, etc) is used on a non-function or on a
8855 function but misplaced before the parameter list.
8857 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8859 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
8860 * support/Util/SDCCerr.h,

8882 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8884 Made the constant following the "interrupt" keyword optional. If
8885 omitted, the function will not automatically be given an entry
8886 in the interrupt vector table (similar to #pragma NOIV, but
8887 less syntacticly kludgy). The interrupt number is also now
8888 range checked. Also fixed a bug in the high order bit example

9419 messages from optionsTable when a port is not configured, added
9420 support for the PIc16 port in the ports table, when executing
9421 the compiler with no port specified on command line, a default
9422 port is selected with the new macro DEFAULT_PORT which is
9423 defined in port.h, in setDefaultOptions() linkOptions is removed
9424 from initialization assignment, since now it is a set,
9425 parseCmdLine uses setParseWithComma for linkOptions, in
9426 linkEdit() linkOptions are accessed with new function indexSet()
9427 which returns the i'th item of a set variable. See SDCCset.c, in
9428 linkEdit() when calling buildCmdLine(), added linkOptions as
9429 last argument. Now users can pass arguments to gplink via the
9430 -Wl option, main() uses pic16glue() to glue up pic16 programs

9444 gpasm complaining and test the linkage with gplink, _linkCmd and
9445 _asmCmd changed to be more gplink and gpasm friendly
9446 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9447 produced an error when parsed, peep rule 12 is added to utilize
9448 movff, but it is commented out since the pCode does not support
9449 yet a command with 2 address arguments
9451 2003-05-18 <johan AT balder>
9453 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

10512 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10514 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10516 * in \sdcc\as\mcs51\ changed these files in order to create an
10517 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10518 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10519 following files to include the previous two files: aslink.dsp,
10520 Makefile.aslink, Makefile.bcc, and Makefile.in.
10522 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10523 .adb instead of .cdb
10525 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10527 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10528 value from option --iram-size.
10530 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10532 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10535 2002-09-18 <wiml AT hhhh.org>
10537 * SDCClrange.h: exposed setFromRange() and setToRange()
10538 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10539 packRegsForAccUse() (bug 542397)
10540 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10541 multiple times and emitting the fetch operations more than once
10542 added aopGetUsesAcc() function to allow binary operators to
10543 fetch their operands in the correct order; made genMinus() emit
10544 compact code for X = LITERAL - Y
10546 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10547 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10548 sprintf() in line 1267.
10550 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10551 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10554 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10555 Changes to aslink (All the changes are marked with 'JCF'):
10557 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10560 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10561 area BSEG. Also moves, if possible, the DATA area down into the internal
10562 ram so more space is available.
10564 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10567 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10568 not bytes. Function summary() which creates a memory usage summary
10569 file with extension .mem. Reports of overlaping stack and small stack
10570 size. If the space for the stack is less than 16 bytes aslink trows a
10573 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10574 the 8051. Option 'y' for memory summary output file.
10576 Changes to sdcc (All the changes are marked with 'JCF'):
10578 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10580 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10581 overlaying area for it (uses RegBankUsed[4]).
10583 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10584 bank zero as used by default. By default aslink locates the stack
10585 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10586 the creation of the .mem file. Delegates the allocation of data area
10587 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10588 the begining of the stack area to aslink.
10590 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10591 glue() in SDCCglue.c creates an area for it.
10593 2002-09-03 Borut Razem <borut.razem AT siol.net>
10594 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10595 sdcc/src/pic/glue.c:
10596 introduced atexit() handler for teporay files removal in case of
10597 errors, assertions, ...
10599 2002-08-29 Borut Razem <borut.razem AT siol.net>
10600 * sdcc/support/cpp2/auto-host_vc_in.h:
10601 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10602 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10603 Maybe there is a similar problem with BORLANDC? It should be checked!
10605 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10606 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10607 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10608 was not executed, and the compiler (cl) launched a warning:
10609 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10611 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10612 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10614 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10615 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10617 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10618 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10619 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10620 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10621 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10622 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10623 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10624 - added Release configuration in VS projects
10625 - review of compiler an linker options
10626 - VC .exe files are generated in bin_vc directory, not to interfere
10627 with binaries generated from other projects (cygwin, mingw, bcc ...)
10629 * sdcc/src/yacc.dsp: added
10631 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10632 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10633 and insert the version number definitions from .version
10635 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10637 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10638 added - genarate auto-host.h using auto-host_vc_in.h as template
10641 removed from CVS, generated automatically
10643 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10644 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10646 2002-08-11 Borut Razem <borut.razem AT siol.net>
10647 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10649 2002-08-10 Borut Razem <borut.razem AT siol.net>
10650 * src/SDCCmain.c (main):
10651 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10652 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10653 The consequence was that some temporary files were not removed.
10656 unification of code in functions tempfilename() and tempfile():
10657 function tempnam() is defined in Visual Studio 6.0 and .NET
10659 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10661 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10662 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10663 - removed compiler command line option /WX: Treats all warnings as errors
10664 - update a list of source files, included into the project
10666 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10667 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10668 changed project type to Generic Project so that can be correcly converted to VS.NET project
10670 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10672 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10674 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10676 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10677 added return 0 statements after assert() to make compiler happy
10679 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10680 added newline in the def file to keep MSC compiler satisfied
10682 * sdcc/src/z80/gen.c:
10683 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10684 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10685 - solved MSC error in function aopDump()
10687 * sdcc_vc.h: define PREFIX as "\\sdcc"
10689 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10690 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

10693 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
10694 - Rewrote the register banking algorithm.
10695 - Added pCode live-range analysis to registers (for now, only non-used and
10696 singly-used registers optimized away)
10698 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
10700 * 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.

10727 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
10729 2002-03-28 Johan Knol <johan AT balder>
10731 * src/SDCCval.c: fixed bug #532436
10733 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10735 Added "char *Processor" field to the port structure.
10738 Added -p option. Allows port dependent processor to be specified.
10741 Initialized the new field char *Processor field to NULL in all ports
10744 Compiler generated registers for interrupt context saving
10745 were not getting allocated.
10747 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
10750 Fixed left shift. Will promote the left side of a left shift
10751 if a) left shifting more than size of operand or b) when assigned
10752 to something size > size of left side
10754 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10756 tons of changes. Register allocation has been
10757 rewritten. Added customization for the various PICs. Flow
10758 analysis is restructured. ...
10760 * src/pic/device.h:
10763 * src/pic/device.c:
10764 Added. device.c is a PIC port hack to accomodate variations
10767 2002-03-13 Michael Hope <michaelh AT vroom>
10769 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
10771 2002-03-04 johanknol <johanknol AT manik>
10773 * /src/SDCCval.c: fixed
10775 const unsigned char arr[][2] = { { 0, 1 } };

10864 * sdcc/src/SDCCloop.c:
10865 Previous fix was not good. basic blocks that have "break" or "return" are
10866 not really partof a loop , but live ranges used in these blocks should
10867 be live thru the entire loop, so set partOfLoop but don't add them to
