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

3074 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
3076 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
3077 loaded with the linker search paths (-L arguments) and the libraries
3078 to be linked with the current source (-l arguments). Changes
3079 currently will affect only the pic16 port.
3080 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3081 include path the port specific paths and port specific libraries,
3082 * gplink command now contains the $3 argument,
3083 * src/pic16/device.h,
3084 * src/pic16/device.c,: structure PIC_device is made public and
3085 renamed to PIC16_device, the same for variable Pics which is renamed

3100 Documenting changes from previous commits.
3101 * configure.in (version 1.56),
3102 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3103 when generating output files to configure the pic16 library,
3104 but now I've commented it out, since gputils aren't installed in the
3105 SF compile farm, so library won't compile
3107 * device/lib/Makefile.in (version 1.56): initially I've added in
3108 target 'all' the prerequestive 'model-pic16' so it compiled the
3109 pic16 library, but now I've commented it out for the same reasons
3111 * added targets 'model-pic16' and 'objects-pic16' to compile the
3113 * added target 'port-specific-objects-pic16' to handle the
3114 generated libraries and copy them into the build/ directory
3115 * added target 'clean-intermediate-pic16' to clean intermediate
3116 files into pic16 directory
3117 * in target 'installdirs' added line to create directory pic16 in
3118 the installation path
3120 * device/include/Makefile.in (version 1.11): in target 'install'
3121 added lines to copy all header files to installation path,
3122 * in target 'installdirs' added line create directory for pic16
3123 headers in the installation path

3139 option so that it actually works. Made it specific to the z80, since
3140 the gbz80 doesn't have these kinds of I/O ports.
3142 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3168 via literal number. The symbol is placed in the corresponding
3169 position of the data ram
3170 * (pic16_dump_section): relocatable and absolute uninitialized
3171 data are now emitted in sorted order to reduce section naming,
3172 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
3173 weren't marked as being in the access bank,
3175 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
3177 Added portion of GNU PIC Library under the directory
3178 device/include/pic16 and device/lib/pic16. These files
3179 contain the declarations of SFRs for the PIC18Fxx2 devices.

3210 all over. Telling LaTeX to be less strict with word spacing
3211 to better keep the right margin. Changed some notes about
3212 maintainance of the ports in section 3.2.1 - is it OK like this?
3214 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

3251 UPPER for immediate operands,
3252 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
3254 * src/pic16/peeph.def: all peepholes with movff are commented out,
3255 because there is a problem in the pcode peep optimizer,
3256 * src/pic16/ralloc.c: the register allocator can now reuse local
3257 function symbols for another function. This saves register usage.
3258 * src/pic16/ralloc.h: added flag isLocal in structure regs,
3260 Added file src/pic16/NOTES with information about program writing on
3261 the current port version.

3321 directive when no overlay data exist
3322 * (picglue): modified to emit uninitialized data segment
3323 according to udata_section_name

3333 2004-01-07 Borut Razem <borut.razem AT siol.net>
3335 * support/scripts/sdcc.nsi: update PATH
3336 * support/scripts/sdcc.ico: craeted

3349 include information about variables allocated to the overlay
3352 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3354 * as/mcs51/lkmain.c: Help about -Y option

3366 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3368 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
3369 (default behaviour).
3371 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3373 A python script to validate compiler diagnostic messages. It can be
3374 used to verify that sdcc complains about bad c source code and
3375 gives a good location of the error.
3376 * support/valdiag/Makefile,
3377 * support/valdiag/valdiag.py,
3378 * support/valdiag/tests/*
3380 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3395 Bug reported from Jesus Calvino-Fraga
3397 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
3399 * sdcc.spec: updated
3400 * device/include/Makefile.in: don't install CVS directories
3401 * device/lib/Makefile.in: added removal of CVS directories after install
3402 * doc/Makefile: fixed install, added local_icons
3403 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
3404 * src/mcs51/gen.c (genRightShift): fixed bug #870788
3405 * src/ds390/gen.c (genRightShift): fixed bug #870788
3406 * src/SDCCast.c (decorateType): fixed bug #870781
3408 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3410 PIC16 port related changes:
3411 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3412 added variable stackPos,
3414 * gen.c: genCall, assignResultValue: added support for
3415 pushing/retrieving function parameters to/from stack,
3416 genFunction,genEndFunction: setup stack frame for the
3418 genAddrOf: will be changed according to bug 863624
3420 * added files genutils.c and genutils.h which contain gen*
3421 debugged and optimised functions extracted from gen.c
3423 * glue.c: added variable 'externs' which holds extern symbols,
3424 pic16emitRegularMap: is modified to properly handle relocatable
3425 symbols under the new scheme,
3426 pic16createInterruptVect: is modified
3427 pic16printPublics: is modified to emit 'global' assembler directives,
3428 added pic16_printExterns to print extern symbols,
3429 pic16glue: initializes stack/frame pointer in the beginning of
3430 the assembly output. Temporary hack, will be corrected later,
3431 because gplink yet does not support stack and SDCC does not
3432 yet support a type of crt0.o object to create the final binary.
3434 * Removed many lines that contain 8051 legacy code.
3435 * The code is finally placed under a 'code' directive.
3436 * Added port specific options.
3438 * _process_pragma: simplified since now we do not need *special*
3439 include file to define SFR registers. But a separate header
3440 will be needed. This will be developed later.
3441 * _pic16_parseOptions: added, parses port specific options:
3442 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3443 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3444 --preplace-udata-with=
3446 * _pic16_setDefaultOptions: modified to initialize section names,
3447 but hack is temporarly out of order since it needs improvement.
3448 * _pic16_genAssemblerPreamble: configuration words are emitted by
3449 their address instead of their name. This part is incomplete and
3450 supports only the 18Fxx2 devices. Other devices will emit an error
3451 during assembly since they do not contain the same set of config
3453 * _pic16_genIVT: is modified,
3455 * pcode.c: added definitions for some hardware registers that are needed
3457 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3458 All PCI entries are updated. Now LFSR is supported.
3459 * Removed pic16_pciTRIS is mentioned by mdubuc in source
3460 * added pic16_newpCodeOpLit2 to support instructions with
3461 two literal arguments
3462 * pic16_pCode2str: corrected code that emits assembler instructions
3463 with two literal operands and those that have an access bit modifier
3464 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
3465 this fixes a bug which caused some labels to be lost, when an
3466 assembler directive was added, i.e. banksel,
3467 * pic16_FixRegisterBanking: improved logic that causes the insertion
3469 * InlineFunction: functions that are called once, are not any more
3470 inlined. This can be a port option in the future,
3472 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
3474 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
3475 hold the corresponding uninitialized symbols,
3476 * pic16_allocProcessorRegister: registers have explicit marked the
3478 * pic16_allocInternalRegister: registers are explicit marked as
3480 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
3481 processing list, so bit registers were lost,
3484 * ralloc.h: added field 'accessBank' and original symbol operand
3485 in register definition,
3486 * removed the field isMapped from register definition,
3488 ** Several functions have been removed from various sources:
3489 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
3490 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
3491 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
3492 pic16_assignRelocatableRegisters
3494 ** others have been introduced:
3495 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
3496 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
3498 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
3500 * support/scripts/inc2h.pl: changed definition of BIT_AT
3501 to emit 'sbit at' instead of 'bit at'. This was a request.
3503 PIC16 port related preliminary changes:
3504 * gen.c: prefixed function popRegFromString with
3505 pic16_ and all references to it corrected
3506 * pcode.c: all pic16_pc_* hardware registers prefixed
3507 with underscore (_),
3508 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
3509 * ralloc.c: newReg(): when register is REG_SFR then
3510 set address to rIdx,
3511 pic16_allocProcessorRegister(): marks register wasUsed=0
3512 pic16_writeUsedRegs(): added a call to assign processor
3513 registers via pic16_assignFixedRegisters
3515 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3517 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
3518 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
3519 variables in unused register banks. Also the SSEG is placed
3520 wherever there is enough space for it, and IDATA can be anywhere
3521 in internal RAM. For now compile using -Wl-Y[stack_size].
3522 The mem file is different for this option as well, since it
3523 makes no sense of talking about DSEG lenght.
3525 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
3527 * src/SDCClrange.c: fixed bug 869095 that caused segfault
3528 in certain cases, e.g. when ROM assignment, patch provided
3529 from Albert den Haan.
3531 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

3673 SDCC_NOGENRAMCLEAR to disable this.
3674 * src/mcs51/peephole.def,
3675 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
3676 (allows non-interrupt and interrupt code to safely compete for a resource
3677 without the non-interrupt code having to disable interrupts)
3679 2003-12-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3681 * src/SDCCicode.c (geniCodeAdd),

3696 2003-12-12 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3698 * src/mcs51/main.c(_mcs51_genRAMCLEAR): using r0 instead of r1/r2.

3701 2003-12-11 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3703 * src/z80/ralloc.c: set DISABLE_PACK_HL = 1 as a temporary fix to bug #855165
3705 2003-12-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3774 it breaks with bitfields, extern declarations, and gcse analysis.
3775 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
3776 could be assigned through a pointer, so don't complain.

4554 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4555 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
4556 type for bits was changed. It resulted in bit variables becoming

4574 A few small changes that speed up the peephole optimizer.
4578 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4580 Try to make the peephole optimizer smarter by maintaining
4581 an association between the assembly source code and the
4582 iCodes that originated them. Put this information to use
4583 with a new peephole rule condition "notVolatile" so that
4584 the rules can be aggressive yet still safe.
4589 * src/mcs51/peeph.def
4591 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4595 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
4596 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
4597 if the left or right operand symbols have the accuse flag set.
4599 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4601 Changed the type of the result of the ! (NOT) operator to char;
4602 previously it returned the same type as the source. This allows
4603 us to eliminate all the genFloatNot functions (all of its target
4604 implementations were very buggy) since !float can use the same
4607 * src/SDCCicode.c (ast2iCode): ! returns char

4616 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4617 1. Interrupt would not compile properly. Ensure PCLATH register is saved
4618 during interrupts. Ensure WSAVE is located at a shared bank address.
4619 2. Fixed page selection in some places
4620 3. Fixed BTFSS/C to where necessary use registers directly and not simply
4621 the registers name strings.
4622 4. Fixed "signed / unsigned compare" compiler warnings.
4623 5. The PIC port manages its own allocation of the general purpose
4624 registers, but makes no attempt to reuse them. As a result when
4625 compiling it soon runs out of general purpose registers. Some
4626 additional code was added to the files pcode.c and device.c to walk
4627 through the function call tree and rename the registers so that they
4637 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

4644 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4646 Made bitfield a distinct type from bit so that bitfields
4647 convert as per ANSI C and bits retain their traditional
4648 boolean style behaviour. Implemented bitfield support in
4656 * src/ds390/gen.c: bit v bitfield split
4657 * src/z80/gen.c: New support for bitfields
4658 * support/regression/tests/bitfields.c: reenabled z80,
4661 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4663 Rules 246.x, 247.x relate to bitfields, the others speed up
4664 access to xdata mapped I/O devices.

4712 Made the constant following the "interrupt" keyword optional. If
4713 omitted, the function will not automatically be given an entry
4714 in the interrupt vector table (similar to #pragma NOIV, but
4715 less syntacticly kludgy). The interrupt number is also now
4716 range checked. Also fixed a bug in the high order bit example

5242 * configure.in: configure for pic16 port,
5243 added --disable-pic16-port
5244 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
5245 * src/SDCCmain.c: linkOptions is changed to set *,
5246 added if/endif conditional macros to remove options help
5247 messages from optionsTable when a port is not configured, added
5248 support for the PIc16 port in the ports table, when executing
5249 the compiler with no port specified on command line, a default
5250 port is selected with the new macro DEFAULT_PORT which is
5251 defined in port.h, in setDefaultOptions() linkOptions is removed
5252 from initialization assignment, since now it is a set,
5253 parseCmdLine uses setParseWithComma for linkOptions, in
5254 linkEdit() linkOptions are accessed with new function indexSet()
5255 which returns the i'th item of a set variable. See SDCCset.c, in
5256 linkEdit() when calling buildCmdLine(), added linkOptions as
5257 last argument. Now users can pass arguments to gplink via the
5258 -Wl option, main() uses pic16glue() to glue up pic16 programs
5259 * src/SDCCpeeph.c: various changes to support pic16
5260 * src/SDCCset.c: added function void *indexSet(set *, int) to
5261 return the i'th item of the set

5264 * src/clean.mk: added pic16 in CLEANALLPORTS variable
5265 * src/port.h: added TARGET_ID_PIC16,TARGET_IS_PIC16 macro,
5266 added macro DEFAULT_PORT
5267 * src/pic/main.c: corrected arguments of gplnk in _linkCmd
5268 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
5270 * src/pic16/glue.c: commented out some error producing lines
5271 * src/pic16/main.c: __config directives are commented out to stop
5272 gpasm complaining and test the linkage with gplink, _linkCmd and
5273 _asmCmd changed to be more gplink and gpasm friendly
5274 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5275 produced an error when parsed, peep rule 12 is added to utilize
5276 movff, but it is commented out since the pCode does not support
5277 yet a command with 2 address arguments
5279 2003-05-18 <johan AT balder>
5281 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

5308 2003-05-11 Borut Razem <borut.razem AT siol.net>
5310 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
5311 the path of bin directory, so that PATH is the only env. variable, which has to be set
5312 in case of standard installation.
5313 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

6316 * src/SDCCicode.c: fixed array add
6318 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
6319 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
6320 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
6322 2003-01-04 <johan AT balder>
6324 * src/SDCCval.c (getNelements): fixed the initialized array of structures
6326 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6327 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
6329 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
6330 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

6337 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
6339 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
6340 * src/mcs51/main.c: removed {bindir}{sep} from aslink
6342 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6344 * in \sdcc\as\mcs51\ changed these files in order to create an
6345 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
6346 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
6347 following files to include the previous two files: aslink.dsp,
6348 Makefile.aslink, Makefile.bcc, and Makefile.in.
6350 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
6351 .adb instead of .cdb
6353 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6355 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
6356 value from option --iram-size.
6358 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6360 * \sdcc\as\mcs51\lklist.c: added boundary check before using
6363 2002-09-18 <wiml AT hhhh.org>
6365 * SDCClrange.h: exposed setFromRange() and setToRange()
6366 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
6367 packRegsForAccUse() (bug 542397)
6368 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
6369 multiple times and emitting the fetch operations more than once
6370 added aopGetUsesAcc() function to allow binary operators to
6371 fetch their operands in the correct order; made genMinus() emit
6372 compact code for X = LITERAL - Y
6374 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6375 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
6376 sprintf() in line 1267.
6378 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6379 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
6382 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6383 Changes to aslink (All the changes are marked with 'JCF'):
6385 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
6388 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
6389 area BSEG. Also moves, if possible, the DATA area down into the internal
6390 ram so more space is available.
6392 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
6395 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6396 not bytes. Function summary() which creates a memory usage summary
6397 file with extension .mem. Reports of overlaping stack and small stack
6398 size. If the space for the stack is less than 16 bytes aslink trows a
6401 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6402 the 8051. Option 'y' for memory summary output file.
6404 Changes to sdcc (All the changes are marked with 'JCF'):
6406 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6408 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6409 overlaying area for it (uses RegBankUsed[4]).
6411 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6412 bank zero as used by default. By default aslink locates the stack
6413 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6414 the creation of the .mem file. Delegates the allocation of data area
6415 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6416 the begining of the stack area to aslink.
6418 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6419 glue() in SDCCglue.c creates an area for it.
6421 2002-09-03 Borut Razem <borut.razem AT siol.net>
6422 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6423 sdcc/src/pic/glue.c:
6424 introduced atexit() handler for teporay files removal in case of
6425 errors, assertions, ...
6427 2002-08-29 Borut Razem <borut.razem AT siol.net>
6428 * sdcc/support/cpp2/auto-host_vc_in.h:
6429 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6430 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6431 Maybe there is a similar problem with BORLANDC? It should be checked!
6433 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6434 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6435 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6436 was not executed, and the compiler (cl) launched a warning:
6437 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6439 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
6440 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
6442 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
6443 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
6445 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6446 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
6447 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
6448 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6449 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
6450 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
6451 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
6452 - added Release configuration in VS projects
6453 - review of compiler an linker options
6454 - VC .exe files are generated in bin_vc directory, not to interfere
6455 with binaries generated from other projects (cygwin, mingw, bcc ...)
6457 * sdcc/src/yacc.dsp: added
6459 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
6460 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
6461 and insert the version number definitions from .version
6463 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
6465 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
6466 added - genarate auto-host.h using auto-host_vc_in.h as template
6469 removed from CVS, generated automatically
6471 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
6472 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
6474 2002-08-11 Borut Razem <borut.razem AT siol.net>
6475 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
6477 2002-08-10 Borut Razem <borut.razem AT siol.net>
6478 * src/SDCCmain.c (main):
6479 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
6480 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
6481 The consequence was that some temporary files were not removed.
6484 unification of code in functions tempfilename() and tempfile():
6485 function tempnam() is defined in Visual Studio 6.0 and .NET
6487 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
6489 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6490 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
6491 - removed compiler command line option /WX: Treats all warnings as errors
6492 - update a list of source files, included into the project
6494 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6495 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
6496 changed project type to Generic Project so that can be correcly converted to VS.NET project
6498 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
6500 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
6502 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
6504 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
6505 added return 0 statements after assert() to make compiler happy
6507 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
6508 added newline in the def file to keep MSC compiler satisfied
6510 * sdcc/src/z80/gen.c:
6511 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
6512 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
6513 - solved MSC error in function aopDump()
6515 * sdcc_vc.h: define PREFIX as "\\sdcc"
6517 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
6518 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
6520 2002-06-22 Scott Dattalo <scott AT dattalo.com>
6521 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
6522 - Rewrote the register banking algorithm.
6523 - Added pCode live-range analysis to registers (for now, only non-used and
6524 singly-used registers optimized away)
6526 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
6528 * 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.
6530 2002-05-10 Scott Dattalo <scott AT dattalo.com>
6531 * src/pic/*: Added support for multiplication. Fixed many,many bugs.
6533 2002-04-22 Michael Hope <michaelh AT vroom>
6535 * device/lib/z80/printf.c: Changed emitter to volatile to work around a pcall bug.
6537 * configure.in (DD_COPT): Added include support required for gbdk.
