2634 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
2636 Enabled VPATH feature: changed nearly all Makefiles (149 files).
2637 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
2639 One basic decision: e.g. src/clean.mk includes further files. In order
2640 to make this work there are two solutions:
2641 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
2642 run configure on them. This way they can use
2643 'include $(srcdir)/port-clean.mk'
2644 - always include clean.mk by the Makefile at the same level. To avoid
2645 that `make clean` tries to include and build Makefile.dep the
2646 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
2647 implemented, because now even `make uninstall` doesn't create
2648 Makefile.in. clean.mk could be eliminated by pasting it in
2651 * debugger/mcs51/Makefile.in: build own objects from library sources
2652 (SLIB, SDCC) in current directory
2654 * configure, configure.in: renamed --disable-device-lib-build in
2655 --disable-device-lib; added --enable-doc, the required tools are
2656 searched by configure; added result message; the toolchain for the
2657 belonging ports are now only built, if the port is enabled.
2659 * support/regression/*: all output is written in directory gen, because
2660 the fwk and ports directories don't livet in the build tree using vpath
2662 * doc/sdccman.lyx: renamed --disable-device-lib-build to
2663 --disable-device-lib, added --enable-doc, added section VPATH
2665 * sim/ucsim/configure.in,
2666 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
2667 z80 are enabled by default
2669 2006-04-24 Raphael Neider <rneider AT web.de>
2671 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
2672 to config word, "pic14_"-prefixed some extern functions
2673 (pic14_emitConfigWord): emit __config directive(s) if assignment to
2674 config word has been found
2675 * src/pic/device.h: added prototypes

2984 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
2985 call to allocReg, not by manually allocating a new one,
2986 (pic16_assignRegisters): now before going through the register
2987 allocating functions mark all registers as free. This eliminates some
2988 side effects resulting from peephole parser done earlier in the backbone

3025 added swappedLR to keep track
3026 * support/regression/fwk/include/testfwk.h: added defines for xdata, idata,

3038 * support/regression/tests/array.c: added parenthesis, made arrays unsigned
3040 2006-03-06 Borut Razem <borut.razem AT siol.net>
3042 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
3043 made the linker quiet
3045 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
3047 * src/pic16/gen.c (genPcall): fixed bug #1443644
3048 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
3049 which dumps before the function entry point a data byte which represents
3050 the number of the local variables used by the specified function, added
3051 'xinst' for initial support for Extended Instruction Support,
3052 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
3053 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
3054 port->fun_prefix anymore (may change later),
3055 (genFunction, genEndFunction): do not store/restore local registers for
3056 _main (this should take care the --main-return command line option in
3058 (genOr): removed some legacy pic-port instructions,
3059 * src/pic16/genarith.c (genAddLit): re-enabled old code because
3060 performing operations with SFR's causes data to be written more than
3061 once to each SFR. Perhaps SFRs should be handled in special cases...
3062 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
3064 * src/pic16/main.c (_process_pragma): stack bound checking did not take

3067 --extended or -y for Extended Instruction Support,
3068 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
3069 (deassignLRs): *** perhaps the most important change, old 'for' code
3070 (commented out for reference), didn't account for some registers which
3071 were left marked 'not free' after a pointer operation. The change
3072 reduces register usage a lot in some cases

5345 * src/SDCCglobal.h (struct options),
5347 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
5348 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
5349 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
5350 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
5351 always available in leading double underscore form. The C99 support is
5352 mostly missing, but it's a start.
5353 * support/regression/tests/bug-227710.c: fixed nonconforming use of
5354 reserved identifier "__data".

5432 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
5434 * device/lib/printf_large.c: removed inline assembly for portability and
5435 readability. Use printf_fast if speed or size are more important.
5436 * src/pic16/gen.c: removed conditions around use of DEBUGpc
5437 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
5439 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
5441 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
5442 prevent compiler warning
5444 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
5446 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
5447 moved to level 0 and declared as static. Also they are explicit
5448 placed in access bank. This was necessery because some times they
5449 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
5450 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
5451 optimizations. Currently only compare to unsigned char is implemented,
5452 * src/pic16/gen.c: added fReturnIdx array,
5453 * (struct resolvedIfx) is moved to gen.h and made public,
5454 * (struct _G): added sregsAlloc and sregsAllocSet fields,
5455 * (aopForSym): added an optimization to directly store in stack of
5456 the operand of a SEND iCode,
5457 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
5458 but as registers instead (AOP_REG) using the fReturnIdx array,
5459 * (pic16_freeAsmop): remove the freed register from the
5460 _G.sregsAlloc field,
5461 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
5462 a compare of 'WREG',
5463 * (pic16_popGetTempRegCond): changed function prototype, now
5464 function takes also a bitVector argument v which holds the current
5465 set of registers that are allocated for stack access by aopForSym,
5466 registers allocated in aopForSym for accessing stack symbols are not
5467 any more part of the functions usedRegs field,
5468 * (genCall): some times aopOp is called for a stack variable to be
5469 send, aopForSym might perform the push, if this is true make sure
5470 that genCall doesn't push the variable twice by testing _G.resDirect,
5471 * (genFunction): changed testing for unspecified interrupt number
5472 from 256 to INTNO_UNSPEC,
5473 * modified selection scheme of frame pointer generation. Previously
5474 if function did use local registers a frame pointer was generated,
5475 now a frame pointer is generated only if function has arguments
5476 (that need PLUSW2 register access), or has stack arguments, or the
5477 compiler is not instructed to omit the frame pointer,
5478 * (genEndFunction): before restoring local registers that were saved
5479 in the function preamble, also restore the registers that *might*
5480 have been allocated for stack access,
5481 * (genRet): removed some old comments,
5482 * (genCmp, the active (RN's) version): added a call to the
5483 pic16_genCmp_special function to perform the compare with a more
5484 robust and optimized way,
5485 * (genInline): a feature has been added in inline code generation,
5486 which allows a wildcard variable substitution when writing inline
5487 assembly. Code is incomplete and experimental therefore undocumented,
5488 * (genCast): changed order of aopOp for result and right to allow
5489 aopForSym to directly load the result if possible,
5490 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
5491 perform an optimized compare on some selected special occasions,
5492 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
5493 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
5494 generate an IVT any more,
5495 * src/pic16/main.c (pic16_optionsTable): added command line option
5497 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
5498 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
5500 * src/pic16/NOTES: Raphael Neider added in list of active developers
5501 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
5502 jumptable_end to prevent bug #,
5503 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
5504 inCond and outCond fields,
5505 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
5506 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
5507 turn off register spilling,
5508 * (packRegsForOneUse): synced with other ports' versions although it
5509 is not used currently,
5510 * (pic16_packRegisters): added an optimization while reading
5511 structure bitfields, some registers may be saved (malloc code is
5512 decreased by 80 bytes)
5514 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
5516 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
5517 left is a bitfield, if yes, then don't optimize assignment. Perhaps
5518 this can be optimized more?
5520 2005-03-10 Raphael Neider <rneider AT web.de>
5522 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
5523 genNearPointerGet): (hopefully) fixed access to bitfields via
5524 pointers (p->bitN = x; and x = p->bitN; failed)
5526 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
5528 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

6158 Adding support for replacing ljmps with sjmps in jumptables
6159 generated for switch statements. For now you need to set the
6160 environment variable SDCC_SJMP_JUMPTABLE to enable this.
6161 Now 4 algorithms for mcs51 jumptable generation are used:
6162 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
6163 addresses loaded pc-relative for up to 112 cases and stack-pushing
6164 target addresses loaded with offset from dptr for up to 256 cases.

6194 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
6196 * added libc directory. The current version of LibC contains string
6197 functions, ctype functions and macros and some functions of the
6198 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
6199 be extensively tested in the future. Standard disclaimer here.
6200 Library is not automatically build yet. But one can build it by
6201 invoking 'make' inside the libc directory.

6212 * (pic16_storeForReturn): optimized return of 0,
6213 * (genCmp): experimental code for new genCmp which uses PIC18's
6214 special compare&skip instructions. Initial tests fail some times
6215 with variables grater than 1 byte in size, so new code is disabled,
6216 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
6218 * (genCast): began a fix to optimize the casting of a bit to another
6219 bit, now assigning a bitfield to another bitfield will fail, sorry,

6228 and 1 for banking instruction,
6229 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
6230 caused stop processing pCodes after a inline assembly block,
6231 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
6232 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
6233 registers when it shouldn't,
6234 * src/pic16/ralloc.c (allocReg): add preliminary support for
6235 supporting a limited set of temporary registers,
6237 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6239 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
6240 genDataPointerSet): ensure assignments always copy in MSB to LSB
6242 (loadRegFromAop): recognize CLRH optimization,
6243 (genFunction): optimize RECEIVE iCodes in reentrant functions
6245 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6247 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

9244 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
9245 loaded with the linker search paths (-L arguments) and the libraries
9246 to be linked with the current source (-l arguments). Changes
9247 currently will affect only the pic16 port.
9248 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
9249 include path the port specific paths and port specific libraries,
9250 * gplink command now contains the $3 argument,
9251 * src/pic16/device.h,
9252 * src/pic16/device.c,: structure PIC_device is made public and

9268 Documenting changes from previous commits.
9269 * configure.in (version 1.56),
9270 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
9271 when generating output files to configure the pic16 library,
9272 but now I've commented it out, since gputils aren't installed in the
9273 SF compile farm, so library won't compile
9275 * device/lib/Makefile.in (version 1.56): initially I've added in
9276 target 'all' the prerequestive 'model-pic16' so it compiled the
9277 pic16 library, but now I've commented it out for the same reasons
9279 * added targets 'model-pic16' and 'objects-pic16' to compile the
9281 * added target 'port-specific-objects-pic16' to handle the
9282 generated libraries and copy them into the build/ directory
9283 * added target 'clean-intermediate-pic16' to clean intermediate
9284 files into pic16 directory
9285 * in target 'installdirs' added line to create directory pic16 in

9289 added lines to copy all header files to installation path,
9290 * in target 'installdirs' added line create directory for pic16
9291 headers in the installation path

9573 * src/ds390/gen.c (genRightShift): fixed bug #870788
9574 * src/SDCCast.c (decorateType): fixed bug #870781
9576 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
9578 PIC16 port related changes:
9579 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
9580 added variable stackPos,
9582 * gen.c: genCall, assignResultValue: added support for
9583 pushing/retrieving function parameters to/from stack,
9584 genFunction,genEndFunction: setup stack frame for the
9586 genAddrOf: will be changed according to bug 863624
9588 * added files genutils.c and genutils.h which contain gen*
9589 debugged and optimised functions extracted from gen.c
9591 * glue.c: added variable 'externs' which holds extern symbols,
9592 pic16emitRegularMap: is modified to properly handle relocatable
9593 symbols under the new scheme,
9594 pic16createInterruptVect: is modified
9595 pic16printPublics: is modified to emit 'global' assembler directives,
9596 added pic16_printExterns to print extern symbols,
9597 pic16glue: initializes stack/frame pointer in the beginning of
9598 the assembly output. Temporary hack, will be corrected later,
9599 because gplink yet does not support stack and SDCC does not
9600 yet support a type of crt0.o object to create the final binary.
9602 * Removed many lines that contain 8051 legacy code.
9603 * The code is finally placed under a 'code' directive.
9604 * Added port specific options.
9606 * _process_pragma: simplified since now we do not need *special*
9607 include file to define SFR registers. But a separate header
9608 will be needed. This will be developed later.
9609 * _pic16_parseOptions: added, parses port specific options:
9610 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
9611 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
9612 --preplace-udata-with=
9614 * _pic16_setDefaultOptions: modified to initialize section names,
9615 but hack is temporarly out of order since it needs improvement.
9616 * _pic16_genAssemblerPreamble: configuration words are emitted by
9617 their address instead of their name. This part is incomplete and
9618 supports only the 18Fxx2 devices. Other devices will emit an error
9619 during assembly since they do not contain the same set of config
9621 * _pic16_genIVT: is modified,
9623 * pcode.c: added definitions for some hardware registers that are needed
9625 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
9626 All PCI entries are updated. Now LFSR is supported.
9627 * Removed pic16_pciTRIS is mentioned by mdubuc in source
9628 * added pic16_newpCodeOpLit2 to support instructions with
9629 two literal arguments
9630 * pic16_pCode2str: corrected code that emits assembler instructions
9631 with two literal operands and those that have an access bit modifier
9632 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
9633 this fixes a bug which caused some labels to be lost, when an
9634 assembler directive was added, i.e. banksel,
9635 * pic16_FixRegisterBanking: improved logic that causes the insertion
9637 * InlineFunction: functions that are called once, are not any more
9638 inlined. This can be a port option in the future,
9640 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
9642 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
9643 hold the corresponding uninitialized symbols,
9644 * pic16_allocProcessorRegister: registers have explicit marked the
9646 * pic16_allocInternalRegister: registers are explicit marked as
9648 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
9649 processing list, so bit registers were lost,
9652 * ralloc.h: added field 'accessBank' and original symbol operand
9653 in register definition,
9654 * removed the field isMapped from register definition,
9656 ** Several functions have been removed from various sources:
9657 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
9658 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
9659 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
9660 pic16_assignRelocatableRegisters
9662 ** others have been introduced:
9663 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
9664 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
9666 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
9668 * support/scripts/inc2h.pl: changed definition of BIT_AT
9669 to emit 'sbit at' instead of 'bit at'. This was a request.
9671 PIC16 port related preliminary changes:
9672 * gen.c: prefixed function popRegFromString with
9673 pic16_ and all references to it corrected
9674 * pcode.c: all pic16_pc_* hardware registers prefixed
9675 with underscore (_),
9676 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
9677 * ralloc.c: newReg(): when register is REG_SFR then
9678 set address to rIdx,
9679 pic16_allocProcessorRegister(): marks register wasUsed=0
9680 pic16_writeUsedRegs(): added a call to assign processor
9681 registers via pic16_assignFixedRegisters
9683 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9685 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
9686 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
9687 variables in unused register banks. Also the SSEG is placed
9688 wherever there is enough space for it, and IDATA can be anywhere
9689 in internal RAM. For now compile using -Wl-Y[stack_size].
9690 The mem file is different for this option as well, since it
9691 makes no sense of talking about DSEG lenght.
9693 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
9695 * src/SDCClrange.c: fixed bug 869095 that caused segfault
9696 in certain cases, e.g. when ROM assignment, patch provided
9697 from Albert den Haan.
9699 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

9938 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9940 * src/SDCCast.c (decorateType): disabled a transformation I added in
9941 revision 1.188 (access to fields of a structure at an absolute address);
9942 it breaks with bitfields, extern declarations, and gcse analysis.
9943 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
9944 could be assigned through a pointer, so don't complain.
9945 * src/SDCCast.c (astErrors),
9947 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

10582 * src/SDCCsymt.c (sclsFromPtr),
10584 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
10585 support for standard C idiom of memory mapped variables; for
10586 example, *((xdata int*)0x1234) = 1 is now internally equivalent
10587 to xdata int at 0x1234 tempvar = 1.

10605 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10607 Fixed bug #621531 (const & volatile confusion in the type chain).
10608 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
10609 refer to the const or volatile state of the pointer itself.

10679 2003-09-04 Bernhard Held <bernhard AT bernhardheld.de>
10681 * device/lib/_mullong.c: replaced int by short for gcc
10683 2003-08-31 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10685 * src/SDCCpeeph.c (notVolatile, notVolatileVariable): handle IFX
10686 and JUMPTABLE iCodes properly now (worked by accident before)
10687 * src/mcs51/gen.c (leftRightUseAcc),
10688 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
10689 iCode properly now. Use getSize instead of nRegs since a & b
10690 aren't part of the nRegs tally.
10692 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
10694 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

10704 copied from genNearPointerSet()
10705 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
10706 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
10707 If they pop r0/r1 they must be called in the opposite order than aopOp().
10708 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
10709 (resp. --stack-auto), prepared for --xstack
10711 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10713 * doc/sdccman.lyx: reverted tables to those in cvs 1.64
10715 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>

10720 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
10722 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10723 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
10724 type for bits was changed. It resulted in bit variables becoming
10725 global, which is not permitted in PIC 14 assembly output.
10727 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10729 * doc/sdccman.lyx: various additions and updates. Rearranged sections
10731 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10733 Z80 and MCS51 linkers complaint if a public symbol is defined
10734 in more than one library module:

10742 A few small changes that speed up the peephole optimizer.
10746 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10748 Try to make the peephole optimizer smarter by maintaining
10749 an association between the assembly source code and the
10750 iCodes that originated them. Put this information to use
10751 with a new peephole rule condition "notVolatile" so that
10752 the rules can be aggressive yet still safe.
10757 * src/mcs51/peeph.def
10759 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10763 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
10764 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
10765 if the left or right operand symbols have the accuse flag set.
10767 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10769 Changed the type of the result of the ! (NOT) operator to char;
10770 previously it returned the same type as the source. This allows
10771 us to eliminate all the genFloatNot functions (all of its target
10772 implementations were very buggy) since !float can use the same
10775 * src/SDCCicode.c (ast2iCode): ! returns char

10784 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10785 1. Interrupt would not compile properly. Ensure PCLATH register is saved
10786 during interrupts. Ensure WSAVE is located at a shared bank address.
10787 2. Fixed page selection in some places
10788 3. Fixed BTFSS/C to where necessary use registers directly and not simply
10789 the registers name strings.
10790 4. Fixed "signed / unsigned compare" compiler warnings.
10791 5. The PIC port manages its own allocation of the general purpose
10792 registers, but makes no attempt to reuse them. As a result when
10793 compiling it soon runs out of general purpose registers. Some
10794 additional code was added to the files pcode.c and device.c to walk
10795 through the function call tree and rename the registers so that they
10805 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
10806 genPlus() & genMinus() when the result is the same as left or right
10808 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

10812 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10814 Made bitfield a distinct type from bit so that bitfields
10815 convert as per ANSI C and bits retain their traditional
10816 boolean style behaviour. Implemented bitfield support in
10824 * src/ds390/gen.c: bit v bitfield split
10825 * src/z80/gen.c: New support for bitfields
10826 * support/regression/tests/bitfields.c: reenabled z80,
10829 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10831 Rules 246.x, 247.x relate to bitfields, the others speed up
10832 access to xdata mapped I/O devices.
10834 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
10836 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10838 Cleaned up genPackBits and genUnpackBits and added two helper
10839 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
10840 for literal assignments in genPackBits (thanks to Frieder for
10846 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10848 Fixed bug #748310 (pointer to function type mishandled when the
10849 function name is omitted). Also fixed a SIGSEGV when a function
10850 attribute (reentrant, etc) is used on a non-function or on a
10851 function but misplaced before the parameter list.
10853 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
10855 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
10856 * support/Util/SDCCerr.h,
10857 * support/Util/SDCCerr.c: Added func attr misuse error msg
10859 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
10861 Fixed bug #787649 by anonymous
10862 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
10863 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
10865 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10867 Fixed numerous bitfield problems.
10869 * src/SDCC.y: More bitfield related error checking

10878 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10880 Made the constant following the "interrupt" keyword optional. If
10881 omitted, the function will not automatically be given an entry
10882 in the interrupt vector table (similar to #pragma NOIV, but
10883 less syntacticly kludgy). The interrupt number is also now
10884 range checked. Also fixed a bug in the high order bit example

10892 * support/Util/SDCCerr.h
10895 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

10898 * src/SDCCicode.c (operandOperation): rewritten some ops
10899 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
10900 * src/SDCCsymt.c (computeType): literals are handled the same way as any
10902 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
10903 be re-activated by defining REDUCE_LITERALS)
10904 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
10905 unsigned, but are signed by default
10906 * src/SDCCval.c (constVal): rearranged
10907 * src/SDCCval.c (valMod): preliminary fix
10908 * src/SDCCval.c (valCastLiteral): use TYPE_* types

10948 * src/SDCCval.c (cheapestVal, valueFromLit): use TYPE_* types
10949 * src/SDCCval.c (constVal): changed default to signed; hex and octal
10950 constants are unsigned; added recognition of "u" flag for unsigned
10951 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
10952 * src/SDCCval.c (valDiv, valMod): fixed signdness

11416 support for the PIc16 port in the ports table, when executing
11417 the compiler with no port specified on command line, a default
11418 port is selected with the new macro DEFAULT_PORT which is
11419 defined in port.h, in setDefaultOptions() linkOptions is removed
11420 from initialization assignment, since now it is a set,
11421 parseCmdLine uses setParseWithComma for linkOptions, in
11422 linkEdit() linkOptions are accessed with new function indexSet()
11423 which returns the i'th item of a set variable. See SDCCset.c, in
11424 linkEdit() when calling buildCmdLine(), added linkOptions as
11425 last argument. Now users can pass arguments to gplink via the

11440 gpasm complaining and test the linkage with gplink, _linkCmd and
11441 _asmCmd changed to be more gplink and gpasm friendly
11442 * src/pic16/peeph.def: peep rule 3 is commented out, since it
11443 produced an error when parsed, peep rule 12 is added to utilize
11444 movff, but it is commented out since the pCode does not support
11445 yet a command with 2 address arguments

12504 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
12505 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
12507 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
12508 * src/mcs51/main.c: removed {bindir}{sep} from aslink
12510 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12512 * in /sdcc/as/mcs51/ changed these files in order to create an
12513 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
12514 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
12515 following files to include the previous two files: aslink.dsp,
12516 Makefile.aslink, Makefile.bcc, and Makefile.in.
12518 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
12519 .adb instead of .cdb
12521 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12523 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
12524 value from option --iram-size.
12526 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12528 * /sdcc/as/mcs51/lklist.c: added boundary check before using
12531 2002-09-18 <wiml AT hhhh.org>
12533 * SDCClrange.h: exposed setFromRange() and setToRange()
12534 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
12535 packRegsForAccUse() (bug 542397)
12536 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
12537 multiple times and emitting the fetch operations more than once
12538 added aopGetUsesAcc() function to allow binary operators to
12539 fetch their operands in the correct order; made genMinus() emit
12540 compact code for X = LITERAL - Y
12542 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12543 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
12544 sprintf() in line 1267.
12546 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12547 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
12550 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12551 Changes to aslink (All the changes are marked with 'JCF'):
12553 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
12556 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
12557 area BSEG. Also moves, if possible, the DATA area down into the internal
12558 ram so more space is available.
12560 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
12563 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
12564 not bytes. Function summary() which creates a memory usage summary
12565 file with extension .mem. Reports of overlaping stack and small stack
12566 size. If the space for the stack is less than 16 bytes aslink trows a
12569 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
12570 the 8051. Option 'y' for memory summary output file.
12572 Changes to sdcc (All the changes are marked with 'JCF'):
12574 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
12576 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
12577 overlaying area for it (uses RegBankUsed[4]).
12579 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
12580 bank zero as used by default. By default aslink locates the stack
12581 (equivalent to --stack-after-data). Pass option 'y' to aslink for
12582 the creation of the .mem file. Delegates the allocation of data area
12583 to aslink (it is not longer 0x30 by default). If --stack-loc passes
12584 the begining of the stack area to aslink.
12586 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
12587 glue() in SDCCglue.c creates an area for it.
12589 2002-09-03 Borut Razem <borut.razem AT siol.net>
12590 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
12591 sdcc/src/pic/glue.c:
12592 introduced atexit() handler for teporay files removal in case of
12593 errors, assertions, ...
12595 2002-08-29 Borut Razem <borut.razem AT siol.net>
12596 * sdcc/support/cpp2/auto-host_vc_in.h:
12597 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
12598 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
12599 Maybe there is a similar problem with BORLANDC? It should be checked!
12601 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
12602 corrected improper use of assert: the assignment to clr variable was done inside the assert.
12603 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
12604 was not executed, and the compiler (cl) launched a warning:
12605 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
12607 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
12608 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
12610 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
12611 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
12613 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12614 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
12615 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
12616 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12617 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
12618 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
12619 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
12620 - added Release configuration in VS projects
12621 - review of compiler an linker options
12622 - VC .exe files are generated in bin_vc directory, not to interfere
12623 with binaries generated from other projects (cygwin, mingw, bcc ...)
12625 * sdcc/src/yacc.dsp: added
12627 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
12628 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
12629 and insert the version number definitions from .version
12631 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
12633 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
12634 added - genarate auto-host.h using auto-host_vc_in.h as template
12637 removed from CVS, generated automatically
12639 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
12640 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
12642 2002-08-11 Borut Razem <borut.razem AT siol.net>
12643 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
12645 2002-08-10 Borut Razem <borut.razem AT siol.net>
12646 * src/SDCCmain.c (main):
12647 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
12648 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
12649 The consequence was that some temporary files were not removed.
12652 unification of code in functions tempfilename() and tempfile():
12653 function tempnam() is defined in Visual Studio 6.0 and .NET
12655 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
12657 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12658 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
12659 - removed compiler command line option /WX: Treats all warnings as errors
12660 - update a list of source files, included into the project
12662 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12663 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
12664 changed project type to Generic Project so that can be correcly converted to VS.NET project
12666 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
12668 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
12670 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
12672 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
12673 added return 0 statements after assert() to make compiler happy
12675 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
12676 added newline in the def file to keep MSC compiler satisfied
12678 * sdcc/src/z80/gen.c:
12679 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
12680 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
12681 - solved MSC error in function aopDump()
12683 * sdcc_vc.h: define PREFIX as "\\sdcc"
12685 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
12686 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

12689 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
12690 - Rewrote the register banking algorithm.
12691 - Added pCode live-range analysis to registers (for now, only non-used and
12692 singly-used registers optimized away)
12694 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
12696 * 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.

12723 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
12725 2002-03-28 Johan Knol <johan AT balder>
12727 * src/SDCCval.c: fixed bug #532436
12729 2002-03-14 Scott Dattalo <scott AT dattalo.com>
12731 Added "char *Processor" field to the port structure.
12734 Added -p option. Allows port dependent processor to be specified.
12737 Initialized the new field char *Processor field to NULL in all ports
12740 Compiler generated registers for interrupt context saving
12741 were not getting allocated.
12743 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
12746 Fixed left shift. Will promote the left side of a left shift
12747 if a) left shifting more than size of operand or b) when assigned
12748 to something size > size of left side
12750 2002-03-14 Scott Dattalo <scott AT dattalo.com>
12752 tons of changes. Register allocation has been
12753 rewritten. Added customization for the various PICs. Flow
12754 analysis is restructured. ...
12756 * src/pic/device.h:
12759 * src/pic/device.c:
12760 Added. device.c is a PIC port hack to accomodate variations
12763 2002-03-13 Michael Hope <michaelh AT vroom>
12765 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
12767 2002-03-04 johanknol <johanknol AT manik>
12769 * /src/SDCCval.c: fixed
12771 const unsigned char arr[][2] = { { 0, 1 } };
12772 t18.c:1: error: Initializer element is not constant
