19 2004-11-24 Vangelis Rokas <vrokas AT otenet.gr>
21 Large cummulative patch for pic16 port.
22 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
23 to call when a stack overflow occurs,
24 * (malloc.h): added CVS Id tag,
25 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
27 * added libc directory. The current version of LibC contains string
28 functions, ctype functions and macros and some functions of the
29 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
30 be extensively tested in the future. Standard disclaimer here.
31 Library is not automatically build yet. But one can build it by
32 invoking 'make' inside the libc directory.
33 * added ADC library under libio. Preliminary version yet.
35 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
36 * src/pic16/gen.c (aopForRemat): asmop size is filled by
37 aopForRemat() now and not by pic16_aopOp(),
38 * (pic16_popGetTempReg): removed warning messgae when allocating
39 temporary registers, its a buggy feature and will be removed,
40 * (pic16_popGet): set register instance field in AOP_CRY,
41 * (pic16_outBitC): fixed for results in size greater than 1,
42 * (genUminusFloat): fixed for pic16, ported code from mcs51,
43 * (pic16_storeForReturn): optimized return of 0,
44 * (genCmp): experimental code for new genCmp which uses PIC18's
45 special compare&skip instructions. Initial tests fail some times
46 with variables grater than 1 byte in size, so new code is disabled,
47 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
49 * (genCast): began a fix to optimize the casting of a bit to another
50 bit, now assigning a bitfield to another bitfield will fail, sorry,
51 * src/pic16/main.c: disabled the use of lr-support feature,
52 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
53 * added some function prototypes, added function _debugf prototype,
54 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
55 bits with offset (case PO_GPR_BIT),
56 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
58 * (isBankInstruction): modified to return 0 for no banking instruction,
59 and 1 for banking instruction,
60 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
61 caused stop processing pCodes after a inline assembly block,
62 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
63 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
64 registers when it shouldn't,
65 * src/pic16/ralloc.c (allocReg): add preliminary support for
66 supporting a limited set of temporary registers,
68 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
70 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
71 genDataPointerSet): ensure assignments always copy in MSB to LSB
73 (loadRegFromAop): recognize CLRH optimization,
74 (genFunction): optimize RECEIVE iCodes in reentrant functions
76 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
78 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
79 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
81 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

3073 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
3075 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
3076 loaded with the linker search paths (-L arguments) and the libraries
3077 to be linked with the current source (-l arguments). Changes
3078 currently will affect only the pic16 port.
3079 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3080 include path the port specific paths and port specific libraries,
3081 * gplink command now contains the $3 argument,
3082 * src/pic16/device.h,
3083 * src/pic16/device.c,: structure PIC_device is made public and
3084 renamed to PIC16_device, the same for variable Pics which is renamed

3099 Documenting changes from previous commits.
3100 * configure.in (version 1.56),
3101 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3102 when generating output files to configure the pic16 library,
3103 but now I've commented it out, since gputils aren't installed in the
3104 SF compile farm, so library won't compile
3106 * device/lib/Makefile.in (version 1.56): initially I've added in
3107 target 'all' the prerequestive 'model-pic16' so it compiled the
3108 pic16 library, but now I've commented it out for the same reasons
3110 * added targets 'model-pic16' and 'objects-pic16' to compile the
3112 * added target 'port-specific-objects-pic16' to handle the
3113 generated libraries and copy them into the build/ directory
3114 * added target 'clean-intermediate-pic16' to clean intermediate
3115 files into pic16 directory
3116 * in target 'installdirs' added line to create directory pic16 in
3117 the installation path

3120 added lines to copy all header files to installation path,
3121 * in target 'installdirs' added line create directory for pic16
3122 headers in the installation path

3166 * src/pic16/device.c: stack is allocated via symbol and not
3167 via literal number. The symbol is placed in the corresponding
3168 position of the data ram
3169 * (pic16_dump_section): relocatable and absolute uninitialized
3170 data are now emitted in sorted order to reduce section naming,
3171 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
3172 weren't marked as being in the access bank,
3174 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
3176 Added portion of GNU PIC Library under the directory
3177 device/include/pic16 and device/lib/pic16. These files
3178 contain the declarations of SFRs for the PIC18Fxx2 devices.
3179 The directory is initialized via configure from toplevel.
3181 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>

3198 in simpler and even better code
3200 2004-01-11 Bernhard Held <bernhard AT bernhardheld.de>
3202 * src/SDCCicode.c (operandOperation): fixed bug #874819

3208 * doc/sdccman.lyx: Moved and added some sections, small changes
3209 all over. Telling LaTeX to be less strict with word spacing
3210 to better keep the right margin. Changed some notes about
3211 maintainance of the ports in section 3.2.1 - is it OK like this?
3213 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

3222 processor registers declared internally by the port are emitted in
3223 the translation as equates,
3224 * src/pic16/gen.c: inline code is passed unprocessed to the

3250 UPPER for immediate operands,
3251 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
3253 * src/pic16/peeph.def: all peepholes with movff are commented out,
3254 because there is a problem in the pcode peep optimizer,
3255 * src/pic16/ralloc.c: the register allocator can now reuse local
3256 function symbols for another function. This saves register usage.
3257 * src/pic16/ralloc.h: added flag isLocal in structure regs,
3259 Added file src/pic16/NOTES with information about program writing on
3260 the current port version.

3313 needLinkerScript flag
3315 * src/pic16/gen.c (genAddrOf): fixed bug #863624
3316 * src/pic/glue.c: added variable udata_section_name to

3319 * (pic14emitOverlay): modified to emit a commented overlay segment
3320 directive when no overlay data exist
3321 * (picglue): modified to emit uninitialized data segment
3322 according to udata_section_name

3332 2004-01-07 Borut Razem <borut.razem AT siol.net>
3334 * support/scripts/sdcc.nsi: update PATH
3335 * support/scripts/sdcc.ico: craeted

3365 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3367 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
3368 (default behaviour).
3370 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3372 A python script to validate compiler diagnostic messages. It can be
3373 used to verify that sdcc complains about bad c source code and
3374 gives a good location of the error.
3375 * support/valdiag/Makefile,
3376 * support/valdiag/valdiag.py,
3377 * support/valdiag/tests/*

3394 Bug reported from Jesus Calvino-Fraga
3396 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
3398 * sdcc.spec: updated
3399 * device/include/Makefile.in: don't install CVS directories
3400 * device/lib/Makefile.in: added removal of CVS directories after install
3401 * doc/Makefile: fixed install, added local_icons
3402 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
3403 * src/mcs51/gen.c (genRightShift): fixed bug #870788
3404 * src/ds390/gen.c (genRightShift): fixed bug #870788
3405 * src/SDCCast.c (decorateType): fixed bug #870781
3407 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3409 PIC16 port related changes:
3410 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3411 added variable stackPos,
3413 * gen.c: genCall, assignResultValue: added support for
3414 pushing/retrieving function parameters to/from stack,
3415 genFunction,genEndFunction: setup stack frame for the
3417 genAddrOf: will be changed according to bug 863624
3419 * added files genutils.c and genutils.h which contain gen*
3420 debugged and optimised functions extracted from gen.c
3422 * glue.c: added variable 'externs' which holds extern symbols,
3423 pic16emitRegularMap: is modified to properly handle relocatable
3424 symbols under the new scheme,
3425 pic16createInterruptVect: is modified
3426 pic16printPublics: is modified to emit 'global' assembler directives,
3427 added pic16_printExterns to print extern symbols,
3428 pic16glue: initializes stack/frame pointer in the beginning of
3429 the assembly output. Temporary hack, will be corrected later,
3430 because gplink yet does not support stack and SDCC does not
3431 yet support a type of crt0.o object to create the final binary.
3433 * Removed many lines that contain 8051 legacy code.
3434 * The code is finally placed under a 'code' directive.
3435 * Added port specific options.
3437 * _process_pragma: simplified since now we do not need *special*
3438 include file to define SFR registers. But a separate header
3439 will be needed. This will be developed later.
3440 * _pic16_parseOptions: added, parses port specific options:
3441 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3442 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3443 --preplace-udata-with=
3445 * _pic16_setDefaultOptions: modified to initialize section names,
3446 but hack is temporarly out of order since it needs improvement.
3447 * _pic16_genAssemblerPreamble: configuration words are emitted by
3448 their address instead of their name. This part is incomplete and
3449 supports only the 18Fxx2 devices. Other devices will emit an error
3450 during assembly since they do not contain the same set of config
3452 * _pic16_genIVT: is modified,
3454 * pcode.c: added definitions for some hardware registers that are needed
3456 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3457 All PCI entries are updated. Now LFSR is supported.
3458 * Removed pic16_pciTRIS is mentioned by mdubuc in source
3459 * added pic16_newpCodeOpLit2 to support instructions with
3460 two literal arguments
3461 * pic16_pCode2str: corrected code that emits assembler instructions
3462 with two literal operands and those that have an access bit modifier
3463 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
3464 this fixes a bug which caused some labels to be lost, when an
3465 assembler directive was added, i.e. banksel,
3466 * pic16_FixRegisterBanking: improved logic that causes the insertion
3468 * InlineFunction: functions that are called once, are not any more
3469 inlined. This can be a port option in the future,
3471 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
3473 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
3474 hold the corresponding uninitialized symbols,
3475 * pic16_allocProcessorRegister: registers have explicit marked the
3477 * pic16_allocInternalRegister: registers are explicit marked as
3479 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
3480 processing list, so bit registers were lost,
3483 * ralloc.h: added field 'accessBank' and original symbol operand
3484 in register definition,
3485 * removed the field isMapped from register definition,
3487 ** Several functions have been removed from various sources:
3488 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
3489 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
3490 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
3491 pic16_assignRelocatableRegisters
3493 ** others have been introduced:
3494 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
3495 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
3497 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
3499 * support/scripts/inc2h.pl: changed definition of BIT_AT
3500 to emit 'sbit at' instead of 'bit at'. This was a request.
3502 PIC16 port related preliminary changes:
3503 * gen.c: prefixed function popRegFromString with
3504 pic16_ and all references to it corrected
3505 * pcode.c: all pic16_pc_* hardware registers prefixed
3506 with underscore (_),
3507 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
3508 * ralloc.c: newReg(): when register is REG_SFR then
3509 set address to rIdx,
3510 pic16_allocProcessorRegister(): marks register wasUsed=0
3511 pic16_writeUsedRegs(): added a call to assign processor
3512 registers via pic16_assignFixedRegisters
3514 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3516 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
3517 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
3518 variables in unused register banks. Also the SSEG is placed
3519 wherever there is enough space for it, and IDATA can be anywhere
3520 in internal RAM. For now compile using -Wl-Y[stack_size].
3521 The mem file is different for this option as well, since it
3522 makes no sense of talking about DSEG lenght.
3524 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
3526 * src/SDCClrange.c: fixed bug 869095 that caused segfault
3527 in certain cases, e.g. when ROM assignment, patch provided
3528 from Albert den Haan.
3530 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

3670 * src/mcs51/main.c: fixed bug #737001 for the mcs51. SDCC clears
3671 xdata and data memory on startup. Set the environment variable
3672 SDCC_NOGENRAMCLEAR to disable this.
3673 * src/mcs51/peephole.def,
3674 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
3675 (allows non-interrupt and interrupt code to safely compete for a resource
3676 without the non-interrupt code having to disable interrupts)
3678 2003-12-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3680 * src/SDCCicode.c (geniCodeAdd),
3681 * src/SDCCast.c (decorateType): fixed bug #857753 (need to be careful
3682 with valFromType if type might be a pointer and host is big endian).

3695 2003-12-12 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3697 * src/mcs51/main.c(_mcs51_genRAMCLEAR): using r0 instead of r1/r2.
3698 Apparently this did not see much testing (endless loop)
3700 2003-12-11 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3702 * src/z80/ralloc.c: set DISABLE_PACK_HL = 1 as a temporary fix to bug #855165
3704 2003-12-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3773 it breaks with bitfields, extern declarations, and gcse analysis.
3774 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
3775 could be assigned through a pointer, so don't complain.

4553 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4554 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
4555 type for bits was changed. It resulted in bit variables becoming
4556 global, which is not permitted in PIC 14 assembly output.

4573 A few small changes that speed up the peephole optimizer.
4577 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4579 Try to make the peephole optimizer smarter by maintaining
4580 an association between the assembly source code and the
4581 iCodes that originated them. Put this information to use
4582 with a new peephole rule condition "notVolatile" so that
4583 the rules can be aggressive yet still safe.
4588 * src/mcs51/peeph.def
4590 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4594 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
4595 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
4596 if the left or right operand symbols have the accuse flag set.
4598 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4600 Changed the type of the result of the ! (NOT) operator to char;
4601 previously it returned the same type as the source. This allows
4602 us to eliminate all the genFloatNot functions (all of its target
4603 implementations were very buggy) since !float can use the same
4606 * src/SDCCicode.c (ast2iCode): ! returns char

4615 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4616 1. Interrupt would not compile properly. Ensure PCLATH register is saved
4617 during interrupts. Ensure WSAVE is located at a shared bank address.
4618 2. Fixed page selection in some places
4619 3. Fixed BTFSS/C to where necessary use registers directly and not simply
4620 the registers name strings.
4621 4. Fixed "signed / unsigned compare" compiler warnings.
4622 5. The PIC port manages its own allocation of the general purpose
4623 registers, but makes no attempt to reuse them. As a result when
4624 compiling it soon runs out of general purpose registers. Some
4625 additional code was added to the files pcode.c and device.c to walk
4626 through the function call tree and rename the registers so that they
4636 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
4637 genPlus() & genMinus() when the result is the same as left or right

4643 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4645 Made bitfield a distinct type from bit so that bitfields
4646 convert as per ANSI C and bits retain their traditional
4647 boolean style behaviour. Implemented bitfield support in
4655 * src/ds390/gen.c: bit v bitfield split
4656 * src/z80/gen.c: New support for bitfields
4657 * support/regression/tests/bitfields.c: reenabled z80,
4660 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4662 Rules 246.x, 247.x relate to bitfields, the others speed up
4663 access to xdata mapped I/O devices.
4665 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x

4669 Cleaned up genPackBits and genUnpackBits and added two helper
4670 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
4671 for literal assignments in genPackBits (thanks to Frieder for
4677 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4679 Fixed bug #748310 (pointer to function type mishandled when the
4680 function name is omitted). Also fixed a SIGSEGV when a function
4681 attribute (reentrant, etc) is used on a non-function or on a
4682 function but misplaced before the parameter list.
4684 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
4686 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

4709 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4711 Made the constant following the "interrupt" keyword optional. If
4712 omitted, the function will not automatically be given an entry
4713 in the interrupt vector table (similar to #pragma NOIV, but
4714 less syntacticly kludgy). The interrupt number is also now
4715 range checked. Also fixed a bug in the high order bit example
4722 * support/Util/SDCCerr.c

4736 unsigned, but are signed by default
4737 * src/SDCCval.c (constVal): rearranged
4738 * src/SDCCval.c (valMod): preliminary fix
4739 * src/SDCCval.c (valCastLiteral): use TYPE_* types

5243 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
5244 * src/SDCCmain.c: linkOptions is changed to set *,
5245 added if/endif conditional macros to remove options help
5246 messages from optionsTable when a port is not configured, added
5247 support for the PIc16 port in the ports table, when executing
5248 the compiler with no port specified on command line, a default
5249 port is selected with the new macro DEFAULT_PORT which is
5250 defined in port.h, in setDefaultOptions() linkOptions is removed
5251 from initialization assignment, since now it is a set,
5252 parseCmdLine uses setParseWithComma for linkOptions, in
5253 linkEdit() linkOptions are accessed with new function indexSet()
5254 which returns the i'th item of a set variable. See SDCCset.c, in
5255 linkEdit() when calling buildCmdLine(), added linkOptions as
5256 last argument. Now users can pass arguments to gplink via the
5257 -Wl option, main() uses pic16glue() to glue up pic16 programs

5269 * src/pic16/glue.c: commented out some error producing lines
5270 * src/pic16/main.c: __config directives are commented out to stop
5271 gpasm complaining and test the linkage with gplink, _linkCmd and
5272 _asmCmd changed to be more gplink and gpasm friendly
5273 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5274 produced an error when parsed, peep rule 12 is added to utilize
5275 movff, but it is commented out since the pCode does not support
5276 yet a command with 2 address arguments

6315 * src/SDCCicode.c: fixed array add
6317 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
6318 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
6319 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
6321 2003-01-04 <johan AT balder>
6323 * src/SDCCval.c (getNelements): fixed the initialized array of structures
6325 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6326 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
6328 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
6329 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

6336 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
6338 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
6339 * src/mcs51/main.c: removed {bindir}{sep} from aslink
6341 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6343 * in \sdcc\as\mcs51\ changed these files in order to create an
6344 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
6345 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
6346 following files to include the previous two files: aslink.dsp,
6347 Makefile.aslink, Makefile.bcc, and Makefile.in.
6349 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
6350 .adb instead of .cdb
6352 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6354 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
6355 value from option --iram-size.
6357 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6359 * \sdcc\as\mcs51\lklist.c: added boundary check before using
6362 2002-09-18 <wiml AT hhhh.org>
6364 * SDCClrange.h: exposed setFromRange() and setToRange()
6365 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
6366 packRegsForAccUse() (bug 542397)
6367 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
6368 multiple times and emitting the fetch operations more than once
6369 added aopGetUsesAcc() function to allow binary operators to
6370 fetch their operands in the correct order; made genMinus() emit
6371 compact code for X = LITERAL - Y
6373 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6374 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
6375 sprintf() in line 1267.
6377 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6378 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
6381 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6382 Changes to aslink (All the changes are marked with 'JCF'):
6384 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
6387 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
6388 area BSEG. Also moves, if possible, the DATA area down into the internal
6389 ram so more space is available.
6391 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
6394 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6395 not bytes. Function summary() which creates a memory usage summary
6396 file with extension .mem. Reports of overlaping stack and small stack
6397 size. If the space for the stack is less than 16 bytes aslink trows a
6400 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6401 the 8051. Option 'y' for memory summary output file.
6403 Changes to sdcc (All the changes are marked with 'JCF'):
6405 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6407 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6408 overlaying area for it (uses RegBankUsed[4]).
6410 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6411 bank zero as used by default. By default aslink locates the stack
6412 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6413 the creation of the .mem file. Delegates the allocation of data area
6414 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6415 the begining of the stack area to aslink.
6417 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6418 glue() in SDCCglue.c creates an area for it.
6420 2002-09-03 Borut Razem <borut.razem AT siol.net>
6421 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6422 sdcc/src/pic/glue.c:
6423 introduced atexit() handler for teporay files removal in case of
6424 errors, assertions, ...
6426 2002-08-29 Borut Razem <borut.razem AT siol.net>
6427 * sdcc/support/cpp2/auto-host_vc_in.h:
6428 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6429 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6430 Maybe there is a similar problem with BORLANDC? It should be checked!
6432 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6433 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6434 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6435 was not executed, and the compiler (cl) launched a warning:
6436 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6438 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
6439 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
6441 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
6442 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
6444 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6445 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
6446 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
6447 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6448 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
6449 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
6450 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
6451 - added Release configuration in VS projects
6452 - review of compiler an linker options
6453 - VC .exe files are generated in bin_vc directory, not to interfere
6454 with binaries generated from other projects (cygwin, mingw, bcc ...)
6456 * sdcc/src/yacc.dsp: added
6458 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
6459 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
6460 and insert the version number definitions from .version
6462 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
6464 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
6465 added - genarate auto-host.h using auto-host_vc_in.h as template
6468 removed from CVS, generated automatically
6470 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
6471 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
6473 2002-08-11 Borut Razem <borut.razem AT siol.net>
6474 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
6476 2002-08-10 Borut Razem <borut.razem AT siol.net>
6477 * src/SDCCmain.c (main):
6478 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
6479 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
6480 The consequence was that some temporary files were not removed.
6483 unification of code in functions tempfilename() and tempfile():
6484 function tempnam() is defined in Visual Studio 6.0 and .NET
6486 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
6488 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6489 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
6490 - removed compiler command line option /WX: Treats all warnings as errors
6491 - update a list of source files, included into the project
6493 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6494 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
6495 changed project type to Generic Project so that can be correcly converted to VS.NET project
6497 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
6499 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
6501 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
6503 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
6504 added return 0 statements after assert() to make compiler happy
6506 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
6507 added newline in the def file to keep MSC compiler satisfied
6509 * sdcc/src/z80/gen.c:
6510 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
6511 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
6512 - solved MSC error in function aopDump()
6514 * sdcc_vc.h: define PREFIX as "\\sdcc"
6516 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
6517 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
6519 2002-06-22 Scott Dattalo <scott AT dattalo.com>
6520 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
6521 - Rewrote the register banking algorithm.
6522 - Added pCode live-range analysis to registers (for now, only non-used and
6523 singly-used registers optimized away)
6525 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
6527 * 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.
6529 2002-05-10 Scott Dattalo <scott AT dattalo.com>
6530 * src/pic/*: Added support for multiplication. Fixed many,many bugs.
6532 2002-04-22 Michael Hope <michaelh AT vroom>
6534 * device/lib/z80/printf.c: Changed emitter to volatile to work around a pcall bug.
6536 * configure.in (DD_COPT): Added include support required for gbdk.
