3 Adding support for replacing ljmps with sjmps in jumptables
4 generated for switch statements. For now you need to set the
5 environment variable SDCC_SJMP_JUMPTABLE to enable this.
6 Now 4 algorithms for mcs51 jumptable generation are used:
7 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
8 addresses loaded pc-relative for up to 112 cases and stack-pushing
9 target addresses loaded with offset from dptr for up to 256 cases.
11 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
12 * src/mcs51/main.c: adapted constants for switch table generation
13 * src/mcs51/peeph.def: added 260.x for replacing ljmp with sjmp

31 * src/pic16/pcode.c: applied patches #1068154 and #1070213
33 2004-11-24 Vangelis Rokas <vrokas AT otenet.gr>
35 Large cummulative patch for pic16 port.
36 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
37 to call when a stack overflow occurs,
38 * (malloc.h): added CVS Id tag,
39 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
41 * added libc directory. The current version of LibC contains string
42 functions, ctype functions and macros and some functions of the
43 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
44 be extensively tested in the future. Standard disclaimer here.
45 Library is not automatically build yet. But one can build it by
46 invoking 'make' inside the libc directory.
47 * added ADC library under libio. Preliminary version yet.
49 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
50 * src/pic16/gen.c (aopForRemat): asmop size is filled by
51 aopForRemat() now and not by pic16_aopOp(),
52 * (pic16_popGetTempReg): removed warning messgae when allocating
53 temporary registers, its a buggy feature and will be removed,
54 * (pic16_popGet): set register instance field in AOP_CRY,
55 * (pic16_outBitC): fixed for results in size greater than 1,
56 * (genUminusFloat): fixed for pic16, ported code from mcs51,
57 * (pic16_storeForReturn): optimized return of 0,
58 * (genCmp): experimental code for new genCmp which uses PIC18's
59 special compare&skip instructions. Initial tests fail some times
60 with variables grater than 1 byte in size, so new code is disabled,
61 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
63 * (genCast): began a fix to optimize the casting of a bit to another
64 bit, now assigning a bitfield to another bitfield will fail, sorry,
65 * src/pic16/main.c: disabled the use of lr-support feature,
66 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
67 * added some function prototypes, added function _debugf prototype,
68 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
69 bits with offset (case PO_GPR_BIT),
70 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
72 * (isBankInstruction): modified to return 0 for no banking instruction,
73 and 1 for banking instruction,
74 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
75 caused stop processing pCodes after a inline assembly block,
76 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
77 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
78 registers when it shouldn't,
79 * src/pic16/ralloc.c (allocReg): add preliminary support for
80 supporting a limited set of temporary registers,
82 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
84 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
85 genDataPointerSet): ensure assignments always copy in MSB to LSB
87 (loadRegFromAop): recognize CLRH optimization,
88 (genFunction): optimize RECEIVE iCodes in reentrant functions
90 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
92 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

3087 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
3089 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
3090 loaded with the linker search paths (-L arguments) and the libraries
3091 to be linked with the current source (-l arguments). Changes
3092 currently will affect only the pic16 port.
3093 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3094 include path the port specific paths and port specific libraries,
3095 * gplink command now contains the $3 argument,
3096 * src/pic16/device.h,
3097 * src/pic16/device.c,: structure PIC_device is made public and
3098 renamed to PIC16_device, the same for variable Pics which is renamed

3113 Documenting changes from previous commits.
3114 * configure.in (version 1.56),
3115 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3116 when generating output files to configure the pic16 library,
3117 but now I've commented it out, since gputils aren't installed in the
3118 SF compile farm, so library won't compile
3120 * device/lib/Makefile.in (version 1.56): initially I've added in
3121 target 'all' the prerequestive 'model-pic16' so it compiled the
3122 pic16 library, but now I've commented it out for the same reasons
3124 * added targets 'model-pic16' and 'objects-pic16' to compile the
3126 * added target 'port-specific-objects-pic16' to handle the
3127 generated libraries and copy them into the build/ directory
3128 * added target 'clean-intermediate-pic16' to clean intermediate
3129 files into pic16 directory
3130 * in target 'installdirs' added line to create directory pic16 in
3131 the installation path
3133 * device/include/Makefile.in (version 1.11): in target 'install'
3134 added lines to copy all header files to installation path,
3135 * in target 'installdirs' added line create directory for pic16
3136 headers in the installation path

3151 * src/z80/main.c (_parseOptions): fixed the portmode= command line
3152 option so that it actually works. Made it specific to the z80, since
3153 the gbz80 doesn't have these kinds of I/O ports.
3155 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3181 via literal number. The symbol is placed in the corresponding
3182 position of the data ram
3183 * (pic16_dump_section): relocatable and absolute uninitialized
3184 data are now emitted in sorted order to reduce section naming,
3185 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
3186 weren't marked as being in the access bank,
3188 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>

3223 all over. Telling LaTeX to be less strict with word spacing
3224 to better keep the right margin. Changed some notes about
3225 maintainance of the ports in section 3.2.1 - is it OK like this?
3227 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

3265 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
3267 * src/pic16/peeph.def: all peepholes with movff are commented out,
3268 because there is a problem in the pcode peep optimizer,
3269 * src/pic16/ralloc.c: the register allocator can now reuse local

3334 directive when no overlay data exist
3335 * (picglue): modified to emit uninitialized data segment
3336 according to udata_section_name

3346 2004-01-07 Borut Razem <borut.razem AT siol.net>
3348 * support/scripts/sdcc.nsi: update PATH
3349 * support/scripts/sdcc.ico: craeted

3362 include information about variables allocated to the overlay
3365 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3367 * as/mcs51/lkmain.c: Help about -Y option

3379 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3381 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
3382 (default behaviour).
3384 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3386 A python script to validate compiler diagnostic messages. It can be
3387 used to verify that sdcc complains about bad c source code and
3388 gives a good location of the error.
3389 * support/valdiag/Makefile,
3390 * support/valdiag/valdiag.py,
3391 * support/valdiag/tests/*
3393 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3406 * src/common.h: added ifndef/define/endif macros
3407 around the header file.
3408 Bug reported from Jesus Calvino-Fraga
3410 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
3412 * sdcc.spec: updated
3413 * device/include/Makefile.in: don't install CVS directories
3414 * device/lib/Makefile.in: added removal of CVS directories after install
3415 * doc/Makefile: fixed install, added local_icons
3416 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
3417 * src/mcs51/gen.c (genRightShift): fixed bug #870788
3418 * src/ds390/gen.c (genRightShift): fixed bug #870788
3419 * src/SDCCast.c (decorateType): fixed bug #870781
3421 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3423 PIC16 port related changes:
3424 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3425 added variable stackPos,
3427 * gen.c: genCall, assignResultValue: added support for
3428 pushing/retrieving function parameters to/from stack,
3429 genFunction,genEndFunction: setup stack frame for the
3431 genAddrOf: will be changed according to bug 863624
3433 * added files genutils.c and genutils.h which contain gen*
3434 debugged and optimised functions extracted from gen.c
3436 * glue.c: added variable 'externs' which holds extern symbols,
3437 pic16emitRegularMap: is modified to properly handle relocatable
3438 symbols under the new scheme,
3439 pic16createInterruptVect: is modified
3440 pic16printPublics: is modified to emit 'global' assembler directives,
3441 added pic16_printExterns to print extern symbols,
3442 pic16glue: initializes stack/frame pointer in the beginning of
3443 the assembly output. Temporary hack, will be corrected later,
3444 because gplink yet does not support stack and SDCC does not
3445 yet support a type of crt0.o object to create the final binary.
3447 * Removed many lines that contain 8051 legacy code.
3448 * The code is finally placed under a 'code' directive.
3449 * Added port specific options.
3451 * _process_pragma: simplified since now we do not need *special*
3452 include file to define SFR registers. But a separate header
3453 will be needed. This will be developed later.
3454 * _pic16_parseOptions: added, parses port specific options:
3455 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3456 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3457 --preplace-udata-with=
3459 * _pic16_setDefaultOptions: modified to initialize section names,
3460 but hack is temporarly out of order since it needs improvement.
3461 * _pic16_genAssemblerPreamble: configuration words are emitted by
3462 their address instead of their name. This part is incomplete and
3463 supports only the 18Fxx2 devices. Other devices will emit an error
3464 during assembly since they do not contain the same set of config
3466 * _pic16_genIVT: is modified,
3468 * pcode.c: added definitions for some hardware registers that are needed
3470 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3471 All PCI entries are updated. Now LFSR is supported.
3472 * Removed pic16_pciTRIS is mentioned by mdubuc in source
3473 * added pic16_newpCodeOpLit2 to support instructions with
3474 two literal arguments
3475 * pic16_pCode2str: corrected code that emits assembler instructions
3476 with two literal operands and those that have an access bit modifier
3477 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
3478 this fixes a bug which caused some labels to be lost, when an
3479 assembler directive was added, i.e. banksel,
3480 * pic16_FixRegisterBanking: improved logic that causes the insertion
3482 * InlineFunction: functions that are called once, are not any more
3483 inlined. This can be a port option in the future,
3485 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
3487 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
3488 hold the corresponding uninitialized symbols,
3489 * pic16_allocProcessorRegister: registers have explicit marked the
3491 * pic16_allocInternalRegister: registers are explicit marked as
3493 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
3494 processing list, so bit registers were lost,
3497 * ralloc.h: added field 'accessBank' and original symbol operand
3498 in register definition,
3499 * removed the field isMapped from register definition,
3501 ** Several functions have been removed from various sources:
3502 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
3503 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
3504 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
3505 pic16_assignRelocatableRegisters
3507 ** others have been introduced:
3508 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
3509 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
3511 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
3513 * support/scripts/inc2h.pl: changed definition of BIT_AT
3514 to emit 'sbit at' instead of 'bit at'. This was a request.
3516 PIC16 port related preliminary changes:
3517 * gen.c: prefixed function popRegFromString with
3518 pic16_ and all references to it corrected
3519 * pcode.c: all pic16_pc_* hardware registers prefixed
3520 with underscore (_),
3521 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
3522 * ralloc.c: newReg(): when register is REG_SFR then
3523 set address to rIdx,
3524 pic16_allocProcessorRegister(): marks register wasUsed=0
3525 pic16_writeUsedRegs(): added a call to assign processor
3526 registers via pic16_assignFixedRegisters
3528 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3530 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
3531 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
3532 variables in unused register banks. Also the SSEG is placed
3533 wherever there is enough space for it, and IDATA can be anywhere
3534 in internal RAM. For now compile using -Wl-Y[stack_size].
3535 The mem file is different for this option as well, since it
3536 makes no sense of talking about DSEG lenght.
3538 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
3540 * src/SDCClrange.c: fixed bug 869095 that caused segfault
3541 in certain cases, e.g. when ROM assignment, patch provided
3542 from Albert den Haan.
3544 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

4567 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4568 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
4569 type for bits was changed. It resulted in bit variables becoming
4570 global, which is not permitted in PIC 14 assembly output.

4587 A few small changes that speed up the peephole optimizer.
4591 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4593 Try to make the peephole optimizer smarter by maintaining
4594 an association between the assembly source code and the
4595 iCodes that originated them. Put this information to use
4596 with a new peephole rule condition "notVolatile" so that
4597 the rules can be aggressive yet still safe.
4602 * src/mcs51/peeph.def
4604 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4608 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
4609 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
4610 if the left or right operand symbols have the accuse flag set.
4612 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4614 Changed the type of the result of the ! (NOT) operator to char;
4615 previously it returned the same type as the source. This allows
4616 us to eliminate all the genFloatNot functions (all of its target
4617 implementations were very buggy) since !float can use the same

4629 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4630 1. Interrupt would not compile properly. Ensure PCLATH register is saved
4631 during interrupts. Ensure WSAVE is located at a shared bank address.
4632 2. Fixed page selection in some places
4633 3. Fixed BTFSS/C to where necessary use registers directly and not simply
4634 the registers name strings.
4635 4. Fixed "signed / unsigned compare" compiler warnings.
4636 5. The PIC port manages its own allocation of the general purpose
4637 registers, but makes no attempt to reuse them. As a result when
4638 compiling it soon runs out of general purpose registers. Some
4639 additional code was added to the files pcode.c and device.c to walk
4640 through the function call tree and rename the registers so that they
4650 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
4651 genPlus() & genMinus() when the result is the same as left or right

4657 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4659 Made bitfield a distinct type from bit so that bitfields
4660 convert as per ANSI C and bits retain their traditional
4661 boolean style behaviour. Implemented bitfield support in

4677 access to xdata mapped I/O devices.
4679 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
4681 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4683 Cleaned up genPackBits and genUnpackBits and added two helper
4684 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
4685 for literal assignments in genPackBits (thanks to Frieder for
4691 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4693 Fixed bug #748310 (pointer to function type mishandled when the
4694 function name is omitted). Also fixed a SIGSEGV when a function
4695 attribute (reentrant, etc) is used on a non-function or on a
4696 function but misplaced before the parameter list.

4725 Made the constant following the "interrupt" keyword optional. If
4726 omitted, the function will not automatically be given an entry
4727 in the interrupt vector table (similar to #pragma NOIV, but
4728 less syntacticly kludgy). The interrupt number is also now
4729 range checked. Also fixed a bug in the high order bit example

4750 unsigned, but are signed by default
4751 * src/SDCCval.c (constVal): rearranged
4752 * src/SDCCval.c (valMod): preliminary fix
4753 * src/SDCCval.c (valCastLiteral): use TYPE_* types

5247 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
5249 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
5250 it can be defined with CFLAGS when running configure
5251 * src/SDCCmain.c: fixed compiling + linking with object files
5253 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
5255 * configure.in: configure for pic16 port,
5256 added --disable-pic16-port
5257 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
5258 * src/SDCCmain.c: linkOptions is changed to set *,
5259 added if/endif conditional macros to remove options help
5260 messages from optionsTable when a port is not configured, added
5261 support for the PIc16 port in the ports table, when executing
5262 the compiler with no port specified on command line, a default
5263 port is selected with the new macro DEFAULT_PORT which is
5264 defined in port.h, in setDefaultOptions() linkOptions is removed
5265 from initialization assignment, since now it is a set,
5266 parseCmdLine uses setParseWithComma for linkOptions, in
5267 linkEdit() linkOptions are accessed with new function indexSet()
5268 which returns the i'th item of a set variable. See SDCCset.c, in
5269 linkEdit() when calling buildCmdLine(), added linkOptions as
5270 last argument. Now users can pass arguments to gplink via the
5271 -Wl option, main() uses pic16glue() to glue up pic16 programs
5272 * src/SDCCpeeph.c: various changes to support pic16

5283 * src/pic16/glue.c: commented out some error producing lines
5284 * src/pic16/main.c: __config directives are commented out to stop
5285 gpasm complaining and test the linkage with gplink, _linkCmd and
5286 _asmCmd changed to be more gplink and gpasm friendly
5287 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5288 produced an error when parsed, peep rule 12 is added to utilize
5289 movff, but it is commented out since the pCode does not support
5290 yet a command with 2 address arguments
5292 2003-05-18 <johan AT balder>
5294 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

5321 2003-05-11 Borut Razem <borut.razem AT siol.net>
5323 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
5324 the path of bin directory, so that PATH is the only env. variable, which has to be set
5325 in case of standard installation.

6312 2003-01-07 <johan AT balder>
6314 * src/SDCCast.c (decorateType): fixed bug #600035

6329 * src/SDCCicode.c: fixed array add
6331 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
6332 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
6333 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
6335 2003-01-04 <johan AT balder>
6337 * src/SDCCval.c (getNelements): fixed the initialized array of structures
6339 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6340 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
6342 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
6343 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

6349 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
6350 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
6352 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
6353 * src/mcs51/main.c: removed {bindir}{sep} from aslink
6355 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6357 * in \sdcc\as\mcs51\ changed these files in order to create an
6358 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
6359 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
6360 following files to include the previous two files: aslink.dsp,
6361 Makefile.aslink, Makefile.bcc, and Makefile.in.
6363 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
6364 .adb instead of .cdb
6366 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6368 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
6369 value from option --iram-size.
6371 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6373 * \sdcc\as\mcs51\lklist.c: added boundary check before using
6376 2002-09-18 <wiml AT hhhh.org>
6378 * SDCClrange.h: exposed setFromRange() and setToRange()
6379 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
6380 packRegsForAccUse() (bug 542397)
6381 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
6382 multiple times and emitting the fetch operations more than once
6383 added aopGetUsesAcc() function to allow binary operators to
6384 fetch their operands in the correct order; made genMinus() emit
6385 compact code for X = LITERAL - Y
6387 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6388 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
6389 sprintf() in line 1267.
6391 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6392 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
6395 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6396 Changes to aslink (All the changes are marked with 'JCF'):
6398 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
6401 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
6402 area BSEG. Also moves, if possible, the DATA area down into the internal
6403 ram so more space is available.
6405 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
6408 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6409 not bytes. Function summary() which creates a memory usage summary
6410 file with extension .mem. Reports of overlaping stack and small stack
6411 size. If the space for the stack is less than 16 bytes aslink trows a
6414 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6415 the 8051. Option 'y' for memory summary output file.
6417 Changes to sdcc (All the changes are marked with 'JCF'):
6419 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6421 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6422 overlaying area for it (uses RegBankUsed[4]).
6424 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6425 bank zero as used by default. By default aslink locates the stack
6426 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6427 the creation of the .mem file. Delegates the allocation of data area
6428 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6429 the begining of the stack area to aslink.
6431 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6432 glue() in SDCCglue.c creates an area for it.
6434 2002-09-03 Borut Razem <borut.razem AT siol.net>
6435 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6436 sdcc/src/pic/glue.c:
6437 introduced atexit() handler for teporay files removal in case of
6438 errors, assertions, ...
6440 2002-08-29 Borut Razem <borut.razem AT siol.net>
6441 * sdcc/support/cpp2/auto-host_vc_in.h:
6442 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6443 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6444 Maybe there is a similar problem with BORLANDC? It should be checked!
6446 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6447 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6448 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6449 was not executed, and the compiler (cl) launched a warning:
6450 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6452 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
6453 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
6455 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
6456 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
6458 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6459 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
6460 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
6461 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6462 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
6463 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
6464 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
6465 - added Release configuration in VS projects
6466 - review of compiler an linker options
6467 - VC .exe files are generated in bin_vc directory, not to interfere
6468 with binaries generated from other projects (cygwin, mingw, bcc ...)
6470 * sdcc/src/yacc.dsp: added
6472 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
6473 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
6474 and insert the version number definitions from .version
6476 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
6478 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
6479 added - genarate auto-host.h using auto-host_vc_in.h as template
6482 removed from CVS, generated automatically
6484 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
6485 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
6487 2002-08-11 Borut Razem <borut.razem AT siol.net>
6488 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
6490 2002-08-10 Borut Razem <borut.razem AT siol.net>
6491 * src/SDCCmain.c (main):
6492 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
6493 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
6494 The consequence was that some temporary files were not removed.
6497 unification of code in functions tempfilename() and tempfile():
6498 function tempnam() is defined in Visual Studio 6.0 and .NET
6500 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
6502 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6503 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
6504 - removed compiler command line option /WX: Treats all warnings as errors
6505 - update a list of source files, included into the project
6507 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6508 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
6509 changed project type to Generic Project so that can be correcly converted to VS.NET project
6511 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
6513 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
6515 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
6517 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
6518 added return 0 statements after assert() to make compiler happy
6520 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
6521 added newline in the def file to keep MSC compiler satisfied
6523 * sdcc/src/z80/gen.c:
6524 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
6525 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
6526 - solved MSC error in function aopDump()
6528 * sdcc_vc.h: define PREFIX as "\\sdcc"
6530 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
6531 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
6533 2002-06-22 Scott Dattalo <scott AT dattalo.com>
6534 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
6535 - Rewrote the register banking algorithm.
6536 - Added pCode live-range analysis to registers (for now, only non-used and
6537 singly-used registers optimized away)
6539 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
6541 * 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.
6543 2002-05-10 Scott Dattalo <scott AT dattalo.com>
6544 * src/pic/*: Added support for multiplication. Fixed many,many bugs.
6546 2002-04-22 Michael Hope <michaelh AT vroom>
6548 * device/lib/z80/printf.c: Changed emitter to volatile to work around a pcall bug.
