2294 * src/pic16/glue.c (pic16emitRegularMap): updated call of decorateType()
2296 2004-01-23 Bernhard Held <bernhard AT bernhardheld.de>
2298 * src/pic/pcode.c (PCodeID): commented out left over debug code
2300 2004-01-20 Bernhard Held <bernhard AT bernhardheld.de>
2302 * support/valdiag/tests/overflow.c: added shift tests
2310 * src/pic/pcodepeep.c,
2311 * src/pic/pcoderegs.c,
2313 * src/pic/ralloc.h: applied patch from Slade Rich;
2314 added support for multiple code pages and multiple RAM banks on the
2315 PIC 14 port. The ASM files now no longer simply assume all the
2316 code / RAM are in the same page / bank. This means the linker can
2317 safely allocate code/RAM of separate ASM files to different pages/banks.
2318 * doc/sdccman.lyx: added Slade's tips
2319 * src/mcs51/peeph.def: fixed bug #880768

2328 * sim/ucsim/gui.src/serio.src/main.cc: Fixed unconditional use of
2331 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
2332 strtof is not part of C89 and isn't included with Mac OS X.
2334 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2336 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

2345 2004-01-19 Bernhard Held <bernhard AT bernhardheld.de>
2347 * src/SDCCicode.c (geniCodeArray): applied patch from Stas Sergeev
2348 proposed in FR #877103
2350 2004-01-18 Bernhard Held <bernhard AT bernhardheld.de>
2352 * src/SDCCval.c (cheapestVal): added missing checks

2361 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
2363 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
2364 loaded with the linker search paths (-L arguments) and the libraries
2365 to be linked with the current source (-l arguments). Changes
2366 currently will affect only the pic16 port.
2367 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
2368 include path the port specific paths and port specific libraries,
2369 * gplink command now contains the $3 argument,
2370 * src/pic16/device.h,
2371 * src/pic16/device.c,: structure PIC_device is made public and
2372 renamed to PIC16_device, the same for variable Pics which is renamed
2373 to Pics16. Updated all references to them.
2374 * src/pic16/glue.c (pic16glue): corrected bug with code
2375 initialization which bypassed the variable initializations block.
2377 * device/lib/pic16/Makefile.rules: removed --penable-stack from
2378 COMPILE_FLAGS and added the --nostdinc option
2380 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2382 * device/include/mc68hc908jb8.h: Register defs for another member

2385 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
2387 Documenting changes from previous commits.
2388 * configure.in (version 1.56),
2389 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
2390 when generating output files to configure the pic16 library,
2391 but now I've commented it out, since gputils aren't installed in the
2392 SF compile farm, so library won't compile
2394 * device/lib/Makefile.in (version 1.56): initially I've added in
2395 target 'all' the prerequestive 'model-pic16' so it compiled the
2396 pic16 library, but now I've commented it out for the same reasons
2398 * added targets 'model-pic16' and 'objects-pic16' to compile the
2400 * added target 'port-specific-objects-pic16' to handle the
2401 generated libraries and copy them into the build/ directory
2402 * added target 'clean-intermediate-pic16' to clean intermediate
2403 files into pic16 directory
2404 * in target 'installdirs' added line to create directory pic16 in
2405 the installation path
2407 * device/include/Makefile.in (version 1.11): in target 'install'
2408 added lines to copy all header files to installation path,
2409 * in target 'installdirs' added line create directory for pic16
2410 headers in the installation path

2425 * src/z80/main.c (_parseOptions): fixed the portmode= command line
2426 option so that it actually works. Made it specific to the z80, since
2427 the gbz80 doesn't have these kinds of I/O ports.
2429 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2431 * device/include/z180.h,

2453 Mainly changes to support compilation of the device libraries
2454 * src/pic16/device.c: stack is allocated via symbol and not
2455 via literal number. The symbol is placed in the corresponding
2456 position of the data ram
2457 * (pic16_dump_section): relocatable and absolute uninitialized
2458 data are now emitted in sorted order to reduce section naming,
2459 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
2460 weren't marked as being in the access bank,
2462 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
2464 Added portion of GNU PIC Library under the directory
2465 device/include/pic16 and device/lib/pic16. These files
2466 contain the declarations of SFRs for the PIC18Fxx2 devices.
2467 The directory is initialized via configure from toplevel.
2469 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
2471 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

2497 all over. Telling LaTeX to be less strict with word spacing
2498 to better keep the right margin. Changed some notes about
2499 maintainance of the ports in section 3.2.1 - is it OK like this?
2501 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

2539 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
2541 * src/pic16/peeph.def: all peepholes with movff are commented out,
2542 because there is a problem in the pcode peep optimizer,
2543 * src/pic16/ralloc.c: the register allocator can now reuse local

2608 directive when no overlay data exist
2609 * (picglue): modified to emit uninitialized data segment
2610 according to udata_section_name

2695 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
2697 PIC16 port related changes:
2698 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
2699 added variable stackPos,
2701 * gen.c: genCall, assignResultValue: added support for
2702 pushing/retrieving function parameters to/from stack,
2703 genFunction,genEndFunction: setup stack frame for the
2705 genAddrOf: will be changed according to bug 863624
2707 * added files genutils.c and genutils.h which contain gen*
2708 debugged and optimised functions extracted from gen.c
2710 * glue.c: added variable 'externs' which holds extern symbols,
2711 pic16emitRegularMap: is modified to properly handle relocatable
2712 symbols under the new scheme,
2713 pic16createInterruptVect: is modified
2714 pic16printPublics: is modified to emit 'global' assembler directives,
2715 added pic16_printExterns to print extern symbols,
2716 pic16glue: initializes stack/frame pointer in the beginning of
2717 the assembly output. Temporary hack, will be corrected later,
2718 because gplink yet does not support stack and SDCC does not
2719 yet support a type of crt0.o object to create the final binary.
2721 * Removed many lines that contain 8051 legacy code.
2722 * The code is finally placed under a 'code' directive.
2723 * Added port specific options.
2725 * _process_pragma: simplified since now we do not need *special*
2726 include file to define SFR registers. But a separate header
2727 will be needed. This will be developed later.
2728 * _pic16_parseOptions: added, parses port specific options:
2729 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
2730 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
2731 --preplace-udata-with=
2733 * _pic16_setDefaultOptions: modified to initialize section names,
2734 but hack is temporarly out of order since it needs improvement.
2735 * _pic16_genAssemblerPreamble: configuration words are emitted by
2736 their address instead of their name. This part is incomplete and
2737 supports only the 18Fxx2 devices. Other devices will emit an error
2738 during assembly since they do not contain the same set of config
2740 * _pic16_genIVT: is modified,
2742 * pcode.c: added definitions for some hardware registers that are needed
2744 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
2745 All PCI entries are updated. Now LFSR is supported.
2746 * Removed pic16_pciTRIS is mentioned by mdubuc in source
2747 * added pic16_newpCodeOpLit2 to support instructions with
2748 two literal arguments
2749 * pic16_pCode2str: corrected code that emits assembler instructions
2750 with two literal operands and those that have an access bit modifier
2751 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
2752 this fixes a bug which caused some labels to be lost, when an
2753 assembler directive was added, i.e. banksel,
2754 * pic16_FixRegisterBanking: improved logic that causes the insertion
2756 * InlineFunction: functions that are called once, are not any more
2757 inlined. This can be a port option in the future,
2759 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
2761 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
2762 hold the corresponding uninitialized symbols,
2763 * pic16_allocProcessorRegister: registers have explicit marked the
2765 * pic16_allocInternalRegister: registers are explicit marked as
2767 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
2768 processing list, so bit registers were lost,
2771 * ralloc.h: added field 'accessBank' and original symbol operand
2772 in register definition,
2773 * removed the field isMapped from register definition,
2775 ** Several functions have been removed from various sources:
2776 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
2777 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
2778 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
2779 pic16_assignRelocatableRegisters
2781 ** others have been introduced:
2782 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
2783 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
2785 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
2787 * support/scripts/inc2h.pl: changed definition of BIT_AT
2788 to emit 'sbit at' instead of 'bit at'. This was a request.
2790 PIC16 port related preliminary changes:
2791 * gen.c: prefixed function popRegFromString with
2792 pic16_ and all references to it corrected
2793 * pcode.c: all pic16_pc_* hardware registers prefixed
2794 with underscore (_),
2795 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
2796 * ralloc.c: newReg(): when register is REG_SFR then
2797 set address to rIdx,
2798 pic16_allocProcessorRegister(): marks register wasUsed=0
2799 pic16_writeUsedRegs(): added a call to assign processor
2800 registers via pic16_assignFixedRegisters
2802 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2804 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
2805 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
2806 variables in unused register banks. Also the SSEG is placed
2807 wherever there is enough space for it, and IDATA can be anywhere
2808 in internal RAM. For now compile using -Wl-Y[stack_size].
2809 The mem file is different for this option as well, since it
2810 makes no sense of talking about DSEG lenght.
2812 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
2814 * src/SDCClrange.c: fixed bug 869095 that caused segfault

3059 * src/SDCCast.c (decorateType): disabled a transformation I added in
3060 revision 1.188 (access to fields of a structure at an absolute address);
3061 it breaks with bitfields, extern declarations, and gcse analysis.
3062 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
3063 could be assigned through a pointer, so don't complain.

3787 reported in bug #800609
3789 2003-09-04 Vangelis Rokas <vrokas AT otenet.gr>
3791 * Top header beautifications in src/pic16 directory:
3792 device.c, device.h, gen.c, gen.h, genarith.c, glue.c, pcode.c,
3793 pcodeflow.c, pcodeflow.h, pcode.h, pcodepeep.c, pcoderegs.c,
3794 pcoderegs.h, ralloc.c, ralloc.h
3795 * main.c: added top header and GPL license notice
3796 * pcode.c: fixed the if-conditional warning
3798 2003-09-04 Bernhard Held <bernhard AT bernhardheld.de>
3800 * device/lib/_mullong.c: replaced int by short for gcc
3802 2003-08-31 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3804 * src/SDCCpeeph.c (notVolatile, notVolatileVariable): handle IFX
3805 and JUMPTABLE iCodes properly now (worked by accident before)
3806 * src/mcs51/gen.c (leftRightUseAcc),
3807 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
3808 iCode properly now. Use getSize instead of nRegs since a & b
3809 aren't part of the nRegs tally.
3811 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
3813 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()
3814 * src/pic16/pcode.c: fix to disable inserting BANKSEL directive
3815 before instructions that use the _STATUS register
3817 2003-08-31 Bernhard Held <bernhard AT bernhardheld.de>
3819 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
3820 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
3821 fetching of the pointer
3822 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
3823 copied from genNearPointerSet()
3824 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
3825 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
3826 If they pop r0/r1 they must be called in the opposite order than aopOp().
3827 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
3828 (resp. --stack-auto), prepared for --xstack
3830 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

3834 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>
3836 * device/lib/_startup.c: quick & dirty fix for ds390/ds400;
3837 these ports have their own __sdcc_external_start()
3839 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
3841 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3842 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
3843 type for bits was changed. It resulted in bit variables becoming
3844 global, which is not permitted in PIC 14 assembly output.
3846 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3848 * doc/sdccman.lyx: various additions and updates. Rearranged sections
3850 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3852 Z80 and MCS51 linkers complaint if a public symbol is defined
3853 in more than one library module:
3857 * as/mcs51/Makefile.in
3859 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3861 A few small changes that speed up the peephole optimizer.
3865 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3867 Try to make the peephole optimizer smarter by maintaining
3868 an association between the assembly source code and the
3869 iCodes that originated them. Put this information to use
3870 with a new peephole rule condition "notVolatile" so that
3871 the rules can be aggressive yet still safe.
3876 * src/mcs51/peeph.def
3878 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3882 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
3883 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
3884 if the left or right operand symbols have the accuse flag set.
3886 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3888 Changed the type of the result of the ! (NOT) operator to char;
3889 previously it returned the same type as the source. This allows
3890 us to eliminate all the genFloatNot functions (all of its target
3891 implementations were very buggy) since !float can use the same
3894 * src/SDCCicode.c (ast2iCode): ! returns char
3895 * src/mcs51/gen.c (genNot, genNotFloat),
3896 * src/ds390/gen.c (genNot, genNotFloat),
3897 * src/z80/gen.c (genNot, genNotFloat),
3898 * src/pic/gen.c (genNot, genNotFloat),
3899 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
3901 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
3903 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3904 1. Interrupt would not compile properly. Ensure PCLATH register is saved
3905 during interrupts. Ensure WSAVE is located at a shared bank address.
3906 2. Fixed page selection in some places
3907 3. Fixed BTFSS/C to where necessary use registers directly and not simply
3908 the registers name strings.
3909 4. Fixed "signed / unsigned compare" compiler warnings.
3910 5. The PIC port manages its own allocation of the general purpose
3911 registers, but makes no attempt to reuse them. As a result when
3912 compiling it soon runs out of general purpose registers. Some
3913 additional code was added to the files pcode.c and device.c to walk
3914 through the function call tree and rename the registers so that they
3924 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
3925 genPlus() & genMinus() when the result is the same as left or right
3927 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3931 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3933 Made bitfield a distinct type from bit so that bitfields
3934 convert as per ANSI C and bits retain their traditional
3935 boolean style behaviour. Implemented bitfield support in
3943 * src/ds390/gen.c: bit v bitfield split
3944 * src/z80/gen.c: New support for bitfields
3945 * support/regression/tests/bitfields.c: reenabled z80,
3948 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3950 Rules 246.x, 247.x relate to bitfields, the others speed up
3951 access to xdata mapped I/O devices.
3953 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
3955 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3957 Cleaned up genPackBits and genUnpackBits and added two helper
3958 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
3959 for literal assignments in genPackBits (thanks to Frieder for
3965 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3967 Fixed bug #748310 (pointer to function type mishandled when the
3968 function name is omitted). Also fixed a SIGSEGV when a function
3969 attribute (reentrant, etc) is used on a non-function or on a
3970 function but misplaced before the parameter list.
3972 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
3974 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
3975 * support/Util/SDCCerr.h,
3976 * support/Util/SDCCerr.c: Added func attr misuse error msg
3978 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
3980 Fixed bug #787649 by anonymous
3981 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr

3997 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3999 Made the constant following the "interrupt" keyword optional. If
4000 omitted, the function will not automatically be given an entry
4001 in the interrupt vector table (similar to #pragma NOIV, but
4002 less syntacticly kludgy). The interrupt number is also now
4003 range checked. Also fixed a bug in the high order bit example
4010 * support/Util/SDCCerr.c
4011 * support/Util/SDCCerr.h
4014 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

4017 * src/SDCCicode.c (operandOperation): rewritten some ops
4018 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
4019 * src/SDCCsymt.c (computeType): literals are handled the same way as any
4021 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
4022 be re-activated by defining REDUCE_LITERALS)
4023 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
4024 unsigned, but are signed by default
4025 * src/SDCCval.c (constVal): rearranged
4026 * src/SDCCval.c (valMod): preliminary fix
4027 * src/SDCCval.c (valCastLiteral): use TYPE_* types

4070 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
4071 * src/SDCCval.c (valDiv, valMod): fixed signdness
4072 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
4073 signedness of modulo, left and right shift

4479 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
4480 the regression tests I'm not brave enough to enable 245.b, 245.c
4481 * doc/sdccman.lyx: added latex preamble for hyperref package.
4482 Using pdflatex this will give you a hyperlinked pdf file with
4483 bookmarks. (prepend '%' before /usepackage if this breaks something)

4521 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
4523 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
4524 it can be defined with CFLAGS when running configure
4525 * src/SDCCmain.c: fixed compiling + linking with object files
4527 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

4530 added --disable-pic16-port
4531 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
4532 * src/SDCCmain.c: linkOptions is changed to set *,
4533 added if/endif conditional macros to remove options help
4534 messages from optionsTable when a port is not configured, added
4535 support for the PIc16 port in the ports table, when executing
4536 the compiler with no port specified on command line, a default
4537 port is selected with the new macro DEFAULT_PORT which is
4538 defined in port.h, in setDefaultOptions() linkOptions is removed
4539 from initialization assignment, since now it is a set,
4540 parseCmdLine uses setParseWithComma for linkOptions, in
4541 linkEdit() linkOptions are accessed with new function indexSet()
4542 which returns the i'th item of a set variable. See SDCCset.c, in
4543 linkEdit() when calling buildCmdLine(), added linkOptions as
4544 last argument. Now users can pass arguments to gplink via the
4545 -Wl option, main() uses pic16glue() to glue up pic16 programs

4557 * src/pic16/glue.c: commented out some error producing lines
4558 * src/pic16/main.c: __config directives are commented out to stop
4559 gpasm complaining and test the linkage with gplink, _linkCmd and
4560 _asmCmd changed to be more gplink and gpasm friendly
4561 * src/pic16/peeph.def: peep rule 3 is commented out, since it
4562 produced an error when parsed, peep rule 12 is added to utilize
4563 movff, but it is commented out since the pCode does not support
4564 yet a command with 2 address arguments
4566 2003-05-18 <johan AT balder>
4568 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
4569 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

4593 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
4595 2003-05-11 Borut Razem <borut.razem AT siol.net>
4597 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
4598 the path of bin directory, so that PATH is the only env. variable, which has to be set
4599 in case of standard installation.
4600 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

5632 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
5633 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
5634 following files to include the previous two files: aslink.dsp,
5635 Makefile.aslink, Makefile.bcc, and Makefile.in.
5637 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
5638 .adb instead of .cdb
5640 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5642 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
5643 value from option --iram-size.
5645 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5647 * \sdcc\as\mcs51\lklist.c: added boundary check before using
5650 2002-09-18 <wiml AT hhhh.org>
5652 * SDCClrange.h: exposed setFromRange() and setToRange()
5653 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
5654 packRegsForAccUse() (bug 542397)
5655 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
5656 multiple times and emitting the fetch operations more than once
5657 added aopGetUsesAcc() function to allow binary operators to
5658 fetch their operands in the correct order; made genMinus() emit
5659 compact code for X = LITERAL - Y
5661 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5662 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
5663 sprintf() in line 1267.
5665 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

5669 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5670 Changes to aslink (All the changes are marked with 'JCF'):
5672 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
5675 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
5676 area BSEG. Also moves, if possible, the DATA area down into the internal
5677 ram so more space is available.
5679 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
5682 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
5683 not bytes. Function summary() which creates a memory usage summary
5684 file with extension .mem. Reports of overlaping stack and small stack
5685 size. If the space for the stack is less than 16 bytes aslink trows a
5688 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
5689 the 8051. Option 'y' for memory summary output file.
5691 Changes to sdcc (All the changes are marked with 'JCF'):
5693 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
5695 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
5696 overlaying area for it (uses RegBankUsed[4]).
5698 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
5699 bank zero as used by default. By default aslink locates the stack
5700 (equivalent to --stack-after-data). Pass option 'y' to aslink for
5701 the creation of the .mem file. Delegates the allocation of data area
5702 to aslink (it is not longer 0x30 by default). If --stack-loc passes
5703 the begining of the stack area to aslink.
5705 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
5706 glue() in SDCCglue.c creates an area for it.

5709 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
5710 sdcc/src/pic/glue.c:
5711 introduced atexit() handler for teporay files removal in case of
5712 errors, assertions, ...
5714 2002-08-29 Borut Razem <borut.razem AT siol.net>
5715 * sdcc/support/cpp2/auto-host_vc_in.h:
5716 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
5717 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
5718 Maybe there is a similar problem with BORLANDC? It should be checked!
5720 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
5721 corrected improper use of assert: the assignment to clr variable was done inside the assert.
5722 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
5723 was not executed, and the compiler (cl) launched a warning:
5724 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
5726 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
5727 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
5729 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
5730 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
5732 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5733 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
5734 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
5735 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5736 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
5737 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
5738 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
5739 - added Release configuration in VS projects
5740 - review of compiler an linker options
5741 - VC .exe files are generated in bin_vc directory, not to interfere
5742 with binaries generated from other projects (cygwin, mingw, bcc ...)
5744 * sdcc/src/yacc.dsp: added
5746 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
5747 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
5748 and insert the version number definitions from .version
5750 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
5752 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
5753 added - genarate auto-host.h using auto-host_vc_in.h as template
5756 removed from CVS, generated automatically
5758 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
5759 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
5761 2002-08-11 Borut Razem <borut.razem AT siol.net>
5762 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
5764 2002-08-10 Borut Razem <borut.razem AT siol.net>
5765 * src/SDCCmain.c (main):
5766 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
5767 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
5768 The consequence was that some temporary files were not removed.
5771 unification of code in functions tempfilename() and tempfile():
5772 function tempnam() is defined in Visual Studio 6.0 and .NET
5774 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
5776 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5777 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
5778 - removed compiler command line option /WX: Treats all warnings as errors
5779 - update a list of source files, included into the project
5781 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5782 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
5783 changed project type to Generic Project so that can be correcly converted to VS.NET project
5785 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
5787 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
5789 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
5791 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
5792 added return 0 statements after assert() to make compiler happy
5794 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
5795 added newline in the def file to keep MSC compiler satisfied
5797 * sdcc/src/z80/gen.c:
5798 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
5799 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
5800 - solved MSC error in function aopDump()
5802 * sdcc_vc.h: define PREFIX as "\\sdcc"
5804 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
5805 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

5853 Added -p option. Allows port dependent processor to be specified.
5856 Initialized the new field char *Processor field to NULL in all ports
5859 Compiler generated registers for interrupt context saving
5860 were not getting allocated.
5862 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
5865 Fixed left shift. Will promote the left side of a left shift
5866 if a) left shifting more than size of operand or b) when assigned
5867 to something size > size of left side
5869 2002-03-14 Scott Dattalo <scott AT dattalo.com>
5871 tons of changes. Register allocation has been
5872 rewritten. Added customization for the various PICs. Flow

5979 * sdcc/src/SDCCloop.c:
5980 Previous fix was not good. basic blocks that have "break" or "return" are
5981 not really partof a loop , but live ranges used in these blocks should
5982 be live thru the entire loop, so set partOfLoop but don't add them to
5985 2002-02-21 <johan AT FRIJA>
5987 * src/SDCCcse.c: fixed bug #514308
5989 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
