55 which dumps before the function entry point a data byte which represents
56 the number of the local variables used by the specified function, added
57 'xinst' for initial support for Extended Instruction Support,
58 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
59 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
60 port->fun_prefix anymore (may change later),

74 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
75 (deassignLRs): *** perhaps the most important change, old 'for' code
76 (commented out for reference), didn't account for some registers which
77 were left marked 'not free' after a pointer operation. The change
78 reduces register usage a lot in some cases

2353 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
2354 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
2355 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
2356 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
2357 always available in leading double underscore form. The C99 support is
2358 mostly missing, but it's a start.
2359 * support/regression/tests/bug-227710.c: fixed nonconforming use of
2360 reserved identifier "__data".

2438 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2440 * device/lib/printf_large.c: removed inline assembly for portability and
2441 readability. Use printf_fast if speed or size are more important.
2442 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2443 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2445 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2447 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2448 prevent compiler warning
2450 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2452 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2453 moved to level 0 and declared as static. Also they are explicit
2454 placed in access bank. This was necessery because some times they
2455 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2456 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2457 optimizations. Currently only compare to unsigned char is implemented,
2458 * src/pic16/gen.c: added fReturnIdx array,
2459 * (struct resolvedIfx) is moved to gen.h and made public,
2460 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2461 * (aopForSym): added an optimization to directly store in stack of
2462 the operand of a SEND iCode,
2463 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2464 but as registers instead (AOP_REG) using the fReturnIdx array,
2465 * (pic16_freeAsmop): remove the freed register from the
2466 _G.sregsAlloc field,
2467 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2468 a compare of 'WREG',
2469 * (pic16_popGetTempRegCond): changed function prototype, now
2470 function takes also a bitVector argument v which holds the current
2471 set of registers that are allocated for stack access by aopForSym,
2472 registers allocated in aopForSym for accessing stack symbols are not
2473 any more part of the functions usedRegs field,
2474 * (genCall): some times aopOp is called for a stack variable to be
2475 send, aopForSym might perform the push, if this is true make sure
2476 that genCall doesn't push the variable twice by testing _G.resDirect,
2477 * (genFunction): changed testing for unspecified interrupt number
2478 from 256 to INTNO_UNSPEC,
2479 * modified selection scheme of frame pointer generation. Previously
2480 if function did use local registers a frame pointer was generated,
2481 now a frame pointer is generated only if function has arguments
2482 (that need PLUSW2 register access), or has stack arguments, or the
2483 compiler is not instructed to omit the frame pointer,
2484 * (genEndFunction): before restoring local registers that were saved
2485 in the function preamble, also restore the registers that *might*
2486 have been allocated for stack access,
2487 * (genRet): removed some old comments,
2488 * (genCmp, the active (RN's) version): added a call to the
2489 pic16_genCmp_special function to perform the compare with a more
2490 robust and optimized way,
2491 * (genInline): a feature has been added in inline code generation,
2492 which allows a wildcard variable substitution when writing inline
2493 assembly. Code is incomplete and experimental therefore undocumented,
2494 * (genCast): changed order of aopOp for result and right to allow
2495 aopForSym to directly load the result if possible,
2496 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2497 perform an optimized compare on some selected special occasions,
2498 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2499 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2500 generate an IVT any more,
2501 * src/pic16/main.c (pic16_optionsTable): added command line option
2503 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2504 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2506 * src/pic16/NOTES: Raphael Neider added in list of active developers
2507 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2508 jumptable_end to prevent bug #,
2509 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2510 inCond and outCond fields,
2511 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2512 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2513 turn off register spilling,
2514 * (packRegsForOneUse): synced with other ports' versions although it
2515 is not used currently,
2516 * (pic16_packRegisters): added an optimization while reading
2517 structure bitfields, some registers may be saved (malloc code is
2518 decreased by 80 bytes)
2520 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2522 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2523 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2524 this can be optimized more?
2526 2005-03-10 Raphael Neider <rneider AT web.de>
2528 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2529 genNearPointerGet): (hopefully) fixed access to bitfields via
2530 pointers (p->bitN = x; and x = p->bitN; failed)
2532 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

2573 2005-02-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
2575 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
2576 to keep the correct label reference count when adding/removing references
2577 to labels. A peephole file using this is appended to patch #1144962.
2579 2005-02-14 Raphael Neider <rneider AT web.de>

3164 Adding support for replacing ljmps with sjmps in jumptables
3165 generated for switch statements. For now you need to set the
3166 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3167 Now 4 algorithms for mcs51 jumptable generation are used:
3168 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
3169 addresses loaded pc-relative for up to 112 cases and stack-pushing
3170 target addresses loaded with offset from dptr for up to 256 cases.

3200 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3202 * added libc directory. The current version of LibC contains string
3203 functions, ctype functions and macros and some functions of the
3204 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3205 be extensively tested in the future. Standard disclaimer here.
3206 Library is not automatically build yet. But one can build it by
3207 invoking 'make' inside the libc directory.
3208 * added ADC library under libio. Preliminary version yet.

3217 * (genUminusFloat): fixed for pic16, ported code from mcs51,
3218 * (pic16_storeForReturn): optimized return of 0,
3219 * (genCmp): experimental code for new genCmp which uses PIC18's
3220 special compare&skip instructions. Initial tests fail some times
3221 with variables grater than 1 byte in size, so new code is disabled,
3222 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3224 * (genCast): began a fix to optimize the casting of a bit to another
3225 bit, now assigning a bitfield to another bitfield will fail, sorry,
3226 * src/pic16/main.c: disabled the use of lr-support feature,
3227 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

3230 bits with offset (case PO_GPR_BIT),
3231 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
3233 * (isBankInstruction): modified to return 0 for no banking instruction,
3234 and 1 for banking instruction,
3235 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3236 caused stop processing pCodes after a inline assembly block,
3237 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
3238 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
3239 registers when it shouldn't,
3240 * src/pic16/ralloc.c (allocReg): add preliminary support for
3241 supporting a limited set of temporary registers,
3243 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3245 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
3246 genDataPointerSet): ensure assignments always copy in MSB to LSB
3248 (loadRegFromAop): recognize CLRH optimization,
3249 (genFunction): optimize RECEIVE iCodes in reentrant functions
3251 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3253 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

6251 loaded with the linker search paths (-L arguments) and the libraries
6252 to be linked with the current source (-l arguments). Changes
6253 currently will affect only the pic16 port.
6254 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6255 include path the port specific paths and port specific libraries,
6256 * gplink command now contains the $3 argument,
6257 * src/pic16/device.h,

6274 Documenting changes from previous commits.
6275 * configure.in (version 1.56),
6276 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6277 when generating output files to configure the pic16 library,
6278 but now I've commented it out, since gputils aren't installed in the
6279 SF compile farm, so library won't compile
6281 * device/lib/Makefile.in (version 1.56): initially I've added in
6282 target 'all' the prerequestive 'model-pic16' so it compiled the
6283 pic16 library, but now I've commented it out for the same reasons
6285 * added targets 'model-pic16' and 'objects-pic16' to compile the
6287 * added target 'port-specific-objects-pic16' to handle the
6288 generated libraries and copy them into the build/ directory
6289 * added target 'clean-intermediate-pic16' to clean intermediate
6290 files into pic16 directory
6291 * in target 'installdirs' added line to create directory pic16 in

6602 added pic16_printExterns to print extern symbols,
6603 pic16glue: initializes stack/frame pointer in the beginning of
6604 the assembly output. Temporary hack, will be corrected later,
6605 because gplink yet does not support stack and SDCC does not
6606 yet support a type of crt0.o object to create the final binary.
6608 * Removed many lines that contain 8051 legacy code.
6609 * The code is finally placed under a 'code' directive.
6610 * Added port specific options.
6612 * _process_pragma: simplified since now we do not need *special*
6613 include file to define SFR registers. But a separate header
6614 will be needed. This will be developed later.
6615 * _pic16_parseOptions: added, parses port specific options:
6616 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6617 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6618 --preplace-udata-with=
6620 * _pic16_setDefaultOptions: modified to initialize section names,
6621 but hack is temporarly out of order since it needs improvement.
6622 * _pic16_genAssemblerPreamble: configuration words are emitted by
6623 their address instead of their name. This part is incomplete and
6624 supports only the 18Fxx2 devices. Other devices will emit an error
6625 during assembly since they do not contain the same set of config
6627 * _pic16_genIVT: is modified,
6629 * pcode.c: added definitions for some hardware registers that are needed
6631 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6632 All PCI entries are updated. Now LFSR is supported.
6633 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6634 * added pic16_newpCodeOpLit2 to support instructions with
6635 two literal arguments
6636 * pic16_pCode2str: corrected code that emits assembler instructions
6637 with two literal operands and those that have an access bit modifier
6638 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6639 this fixes a bug which caused some labels to be lost, when an
6640 assembler directive was added, i.e. banksel,
6641 * pic16_FixRegisterBanking: improved logic that causes the insertion
6643 * InlineFunction: functions that are called once, are not any more
6644 inlined. This can be a port option in the future,
6646 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6648 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6649 hold the corresponding uninitialized symbols,
6650 * pic16_allocProcessorRegister: registers have explicit marked the
6652 * pic16_allocInternalRegister: registers are explicit marked as
6654 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6655 processing list, so bit registers were lost,
6658 * ralloc.h: added field 'accessBank' and original symbol operand
6659 in register definition,
6660 * removed the field isMapped from register definition,
6662 ** Several functions have been removed from various sources:
6663 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6664 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6665 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6666 pic16_assignRelocatableRegisters
6668 ** others have been introduced:
6669 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6670 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6672 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6674 * support/scripts/inc2h.pl: changed definition of BIT_AT
6675 to emit 'sbit at' instead of 'bit at'. This was a request.
6677 PIC16 port related preliminary changes:
6678 * gen.c: prefixed function popRegFromString with
6679 pic16_ and all references to it corrected
6680 * pcode.c: all pic16_pc_* hardware registers prefixed
6681 with underscore (_),
6682 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6683 * ralloc.c: newReg(): when register is REG_SFR then
6684 set address to rIdx,
6685 pic16_allocProcessorRegister(): marks register wasUsed=0
6686 pic16_writeUsedRegs(): added a call to assign processor
6687 registers via pic16_assignFixedRegisters
6689 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6691 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6692 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6693 variables in unused register banks. Also the SSEG is placed
6694 wherever there is enough space for it, and IDATA can be anywhere
6695 in internal RAM. For now compile using -Wl-Y[stack_size].
6696 The mem file is different for this option as well, since it
6697 makes no sense of talking about DSEG lenght.
6699 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6701 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6702 in certain cases, e.g. when ROM assignment, patch provided
6703 from Albert den Haan.

6944 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6946 * src/SDCCast.c (decorateType): disabled a transformation I added in
6947 revision 1.188 (access to fields of a structure at an absolute address);
6948 it breaks with bitfields, extern declarations, and gcse analysis.
6949 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
6950 could be assigned through a pointer, so don't complain.
6951 * src/SDCCast.c (astErrors),
6953 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

7055 * src/mcs51/main.c: started fixing bug #737001 (SDCC not clearing
7056 uninitialized variables) for the mcs51. Set environment variable
7057 SDCC_GENRAMCLEAR to test.
7058 xdata initialization slightly shorter
7060 2003-11-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7707 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
7708 fetching of the pointer
7709 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
7710 copied from genNearPointerSet()
7711 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
7712 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

7728 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7729 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7730 type for bits was changed. It resulted in bit variables becoming
7731 global, which is not permitted in PIC 14 assembly output.
7733 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

7748 A few small changes that speed up the peephole optimizer.
7752 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7754 Try to make the peephole optimizer smarter by maintaining
7755 an association between the assembly source code and the
7756 iCodes that originated them. Put this information to use
7757 with a new peephole rule condition "notVolatile" so that
7758 the rules can be aggressive yet still safe.
7763 * src/mcs51/peeph.def
7765 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7769 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7770 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7771 if the left or right operand symbols have the accuse flag set.
7773 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7775 Changed the type of the result of the ! (NOT) operator to char;
7776 previously it returned the same type as the source. This allows
7777 us to eliminate all the genFloatNot functions (all of its target
7778 implementations were very buggy) since !float can use the same

7790 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7791 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7792 during interrupts. Ensure WSAVE is located at a shared bank address.
7793 2. Fixed page selection in some places
7794 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7795 the registers name strings.
7796 4. Fixed "signed / unsigned compare" compiler warnings.
7797 5. The PIC port manages its own allocation of the general purpose
7798 registers, but makes no attempt to reuse them. As a result when
7799 compiling it soon runs out of general purpose registers. Some
7800 additional code was added to the files pcode.c and device.c to walk
7801 through the function call tree and rename the registers so that they
7811 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

7818 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7820 Made bitfield a distinct type from bit so that bitfields
7821 convert as per ANSI C and bits retain their traditional
7822 boolean style behaviour. Implemented bitfield support in
7830 * src/ds390/gen.c: bit v bitfield split
7831 * src/z80/gen.c: New support for bitfields
7832 * support/regression/tests/bitfields.c: reenabled z80,
7835 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7837 Rules 246.x, 247.x relate to bitfields, the others speed up
7838 access to xdata mapped I/O devices.
7840 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7842 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7844 Cleaned up genPackBits and genUnpackBits and added two helper
7845 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7846 for literal assignments in genPackBits (thanks to Frieder for
7852 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7854 Fixed bug #748310 (pointer to function type mishandled when the
7855 function name is omitted). Also fixed a SIGSEGV when a function
7856 attribute (reentrant, etc) is used on a non-function or on a
7857 function but misplaced before the parameter list.
7859 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
7861 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
7862 * support/Util/SDCCerr.h,

7884 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7886 Made the constant following the "interrupt" keyword optional. If
7887 omitted, the function will not automatically be given an entry
7888 in the interrupt vector table (similar to #pragma NOIV, but
7889 less syntacticly kludgy). The interrupt number is also now
7890 range checked. Also fixed a bug in the high order bit example

7904 * src/SDCCicode.c (operandOperation): rewritten some ops
7905 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
7906 * src/SDCCsymt.c (computeType): literals are handled the same way as any
7908 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
7909 be re-activated by defining REDUCE_LITERALS)
7910 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
7911 unsigned, but are signed by default
7912 * src/SDCCval.c (constVal): rearranged
7913 * src/SDCCval.c (valMod): preliminary fix
7914 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8419 * src/SDCCmain.c: linkOptions is changed to set *,
8420 added if/endif conditional macros to remove options help
8421 messages from optionsTable when a port is not configured, added
8422 support for the PIc16 port in the ports table, when executing
8423 the compiler with no port specified on command line, a default
8424 port is selected with the new macro DEFAULT_PORT which is
8425 defined in port.h, in setDefaultOptions() linkOptions is removed
8426 from initialization assignment, since now it is a set,
8427 parseCmdLine uses setParseWithComma for linkOptions, in
8428 linkEdit() linkOptions are accessed with new function indexSet()
8429 which returns the i'th item of a set variable. See SDCCset.c, in
8430 linkEdit() when calling buildCmdLine(), added linkOptions as
8431 last argument. Now users can pass arguments to gplink via the
8432 -Wl option, main() uses pic16glue() to glue up pic16 programs

8444 * src/pic16/glue.c: commented out some error producing lines
8445 * src/pic16/main.c: __config directives are commented out to stop
8446 gpasm complaining and test the linkage with gplink, _linkCmd and
8447 _asmCmd changed to be more gplink and gpasm friendly
8448 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8449 produced an error when parsed, peep rule 12 is added to utilize
8450 movff, but it is commented out since the pCode does not support
8451 yet a command with 2 address arguments
8453 2003-05-18 <johan AT balder>
8455 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

8480 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
8482 2003-05-11 Borut Razem <borut.razem AT siol.net>
8484 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
8485 the path of bin directory, so that PATH is the only env. variable, which has to be set
8486 in case of standard installation.
8487 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

9519 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9520 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9521 following files to include the previous two files: aslink.dsp,
9522 Makefile.aslink, Makefile.bcc, and Makefile.in.
9524 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9525 .adb instead of .cdb
9527 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9529 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9530 value from option --iram-size.
9532 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9534 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9537 2002-09-18 <wiml AT hhhh.org>
9539 * SDCClrange.h: exposed setFromRange() and setToRange()
9540 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9541 packRegsForAccUse() (bug 542397)
9542 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9543 multiple times and emitting the fetch operations more than once
9544 added aopGetUsesAcc() function to allow binary operators to
9545 fetch their operands in the correct order; made genMinus() emit
9546 compact code for X = LITERAL - Y
9548 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9549 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9550 sprintf() in line 1267.
9552 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9553 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9556 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9557 Changes to aslink (All the changes are marked with 'JCF'):
9559 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9562 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9563 area BSEG. Also moves, if possible, the DATA area down into the internal
9564 ram so more space is available.
9566 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9569 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9570 not bytes. Function summary() which creates a memory usage summary
9571 file with extension .mem. Reports of overlaping stack and small stack
9572 size. If the space for the stack is less than 16 bytes aslink trows a
9575 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9576 the 8051. Option 'y' for memory summary output file.
9578 Changes to sdcc (All the changes are marked with 'JCF'):
9580 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9582 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9583 overlaying area for it (uses RegBankUsed[4]).
9585 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9586 bank zero as used by default. By default aslink locates the stack
9587 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9588 the creation of the .mem file. Delegates the allocation of data area
9589 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9590 the begining of the stack area to aslink.
9592 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9593 glue() in SDCCglue.c creates an area for it.
9595 2002-09-03 Borut Razem <borut.razem AT siol.net>
9596 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9597 sdcc/src/pic/glue.c:
9598 introduced atexit() handler for teporay files removal in case of
9599 errors, assertions, ...
9601 2002-08-29 Borut Razem <borut.razem AT siol.net>
9602 * sdcc/support/cpp2/auto-host_vc_in.h:
9603 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9604 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9605 Maybe there is a similar problem with BORLANDC? It should be checked!
9607 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9608 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9609 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9610 was not executed, and the compiler (cl) launched a warning:
9611 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9613 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9614 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9616 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9617 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9619 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9620 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9621 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9622 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9623 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9624 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9625 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9626 - added Release configuration in VS projects
9627 - review of compiler an linker options
9628 - VC .exe files are generated in bin_vc directory, not to interfere
9629 with binaries generated from other projects (cygwin, mingw, bcc ...)
9631 * sdcc/src/yacc.dsp: added
9633 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9634 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9635 and insert the version number definitions from .version
9637 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9639 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9640 added - genarate auto-host.h using auto-host_vc_in.h as template
9643 removed from CVS, generated automatically
9645 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9646 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9648 2002-08-11 Borut Razem <borut.razem AT siol.net>
9649 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9651 2002-08-10 Borut Razem <borut.razem AT siol.net>
9652 * src/SDCCmain.c (main):
9653 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9654 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9655 The consequence was that some temporary files were not removed.
9658 unification of code in functions tempfilename() and tempfile():
9659 function tempnam() is defined in Visual Studio 6.0 and .NET
9661 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9663 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9664 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9665 - removed compiler command line option /WX: Treats all warnings as errors
9666 - update a list of source files, included into the project
9668 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9669 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9670 changed project type to Generic Project so that can be correcly converted to VS.NET project
9672 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9674 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9676 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9678 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9679 added return 0 statements after assert() to make compiler happy
9681 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9682 added newline in the def file to keep MSC compiler satisfied
9684 * sdcc/src/z80/gen.c:
9685 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9686 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9687 - solved MSC error in function aopDump()
9689 * sdcc_vc.h: define PREFIX as "\\sdcc"
9691 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9692 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

9695 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
9696 - Rewrote the register banking algorithm.
9697 - Added pCode live-range analysis to registers (for now, only non-used and
9698 singly-used registers optimized away)
9700 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis

9731 2002-03-28 Johan Knol <johan AT balder>
9733 * src/SDCCval.c: fixed bug #532436
9735 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9737 Added "char *Processor" field to the port structure.
9740 Added -p option. Allows port dependent processor to be specified.
9743 Initialized the new field char *Processor field to NULL in all ports
9746 Compiler generated registers for interrupt context saving
9747 were not getting allocated.
9749 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9752 Fixed left shift. Will promote the left side of a left shift
9753 if a) left shifting more than size of operand or b) when assigned
9754 to something size > size of left side
9756 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9758 tons of changes. Register allocation has been
9759 rewritten. Added customization for the various PICs. Flow
9760 analysis is restructured. ...
9766 Added. device.c is a PIC port hack to accomodate variations
9769 2002-03-13 Michael Hope <michaelh AT vroom>
9771 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.

9864 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
9866 * sdcc/src/SDCCloop.c:
9867 Previous fix was not good. basic blocks that have "break" or "return" are
9868 not really partof a loop , but live ranges used in these blocks should
9869 be live thru the entire loop, so set partOfLoop but don't add them to
9872 2002-02-21 <johan AT FRIJA>
9874 * src/SDCCcse.c: fixed bug #514308
9876 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>

9880 statement inside a loop, it was not being considered part of the loop.
9882 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
9884 2002-02-10 Karl Bongers <karl AT turbobit.com>
9887 Fixed up SDCDB debugger somewhat. Updated debugger/README
9888 with lots of comments and notes.
9890 * device/examples/test2.c:
9891 Fix bug, "red" variable not being initialized(compiler complained).

9942 set preprocessor defines (depending on options)
9944 * src/SDCCicode.c, src/SDCCicode.h:
9945 changes made to handle multiple sends & receives
9948 Added options --protect-sp-update (ds390) and --parms-in-bank1 (ds390/mcs51)
