41 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
44 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
46 * src/pic16/gen.c (genPcall): fixed bug #1443644
47 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
48 which dumps before the function entry point a data byte which represents
49 the number of the local variables used by the specified function, added
50 'xinst' for initial support for Extended Instruction Support,
51 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
52 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
53 port->fun_prefix anymore (may change later),

66 --extended or -y for Extended Instruction Support,
67 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
68 (deassignLRs): *** perhaps the most important change, old 'for' code
69 (commented out for reference), didn't account for some registers which
70 were left marked 'not free' after a pointer operation. The change
71 reduces register usage a lot in some cases

2346 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
2347 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
2348 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
2349 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
2350 always available in leading double underscore form. The C99 support is
2351 mostly missing, but it's a start.
2352 * support/regression/tests/bug-227710.c: fixed nonconforming use of

2431 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2433 * device/lib/printf_large.c: removed inline assembly for portability and
2434 readability. Use printf_fast if speed or size are more important.
2435 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2436 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2438 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2440 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2441 prevent compiler warning
2443 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2445 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2446 moved to level 0 and declared as static. Also they are explicit
2447 placed in access bank. This was necessery because some times they
2448 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2449 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2450 optimizations. Currently only compare to unsigned char is implemented,
2451 * src/pic16/gen.c: added fReturnIdx array,
2452 * (struct resolvedIfx) is moved to gen.h and made public,
2453 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2454 * (aopForSym): added an optimization to directly store in stack of
2455 the operand of a SEND iCode,
2456 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2457 but as registers instead (AOP_REG) using the fReturnIdx array,
2458 * (pic16_freeAsmop): remove the freed register from the
2459 _G.sregsAlloc field,
2460 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2461 a compare of 'WREG',
2462 * (pic16_popGetTempRegCond): changed function prototype, now
2463 function takes also a bitVector argument v which holds the current
2464 set of registers that are allocated for stack access by aopForSym,
2465 registers allocated in aopForSym for accessing stack symbols are not
2466 any more part of the functions usedRegs field,
2467 * (genCall): some times aopOp is called for a stack variable to be
2468 send, aopForSym might perform the push, if this is true make sure
2469 that genCall doesn't push the variable twice by testing _G.resDirect,
2470 * (genFunction): changed testing for unspecified interrupt number
2471 from 256 to INTNO_UNSPEC,
2472 * modified selection scheme of frame pointer generation. Previously
2473 if function did use local registers a frame pointer was generated,
2474 now a frame pointer is generated only if function has arguments
2475 (that need PLUSW2 register access), or has stack arguments, or the
2476 compiler is not instructed to omit the frame pointer,
2477 * (genEndFunction): before restoring local registers that were saved
2478 in the function preamble, also restore the registers that *might*
2479 have been allocated for stack access,
2480 * (genRet): removed some old comments,
2481 * (genCmp, the active (RN's) version): added a call to the
2482 pic16_genCmp_special function to perform the compare with a more
2483 robust and optimized way,
2484 * (genInline): a feature has been added in inline code generation,
2485 which allows a wildcard variable substitution when writing inline
2486 assembly. Code is incomplete and experimental therefore undocumented,
2487 * (genCast): changed order of aopOp for result and right to allow
2488 aopForSym to directly load the result if possible,
2489 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2490 perform an optimized compare on some selected special occasions,
2491 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2492 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2493 generate an IVT any more,
2494 * src/pic16/main.c (pic16_optionsTable): added command line option
2496 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2497 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2499 * src/pic16/NOTES: Raphael Neider added in list of active developers
2500 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2501 jumptable_end to prevent bug #,
2502 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2503 inCond and outCond fields,
2504 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2505 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2506 turn off register spilling,
2507 * (packRegsForOneUse): synced with other ports' versions although it
2508 is not used currently,
2509 * (pic16_packRegisters): added an optimization while reading
2510 structure bitfields, some registers may be saved (malloc code is
2511 decreased by 80 bytes)
2513 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2515 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2516 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2517 this can be optimized more?
2519 2005-03-10 Raphael Neider <rneider AT web.de>
2521 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2522 genNearPointerGet): (hopefully) fixed access to bitfields via
2523 pointers (p->bitN = x; and x = p->bitN; failed)

2569 to keep the correct label reference count when adding/removing references
2570 to labels. A peephole file using this is appended to patch #1144962.
2572 2005-02-14 Raphael Neider <rneider AT web.de>

3157 Adding support for replacing ljmps with sjmps in jumptables
3158 generated for switch statements. For now you need to set the
3159 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3160 Now 4 algorithms for mcs51 jumptable generation are used:
3161 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
3162 addresses loaded pc-relative for up to 112 cases and stack-pushing
3163 target addresses loaded with offset from dptr for up to 256 cases.

3193 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3195 * added libc directory. The current version of LibC contains string
3196 functions, ctype functions and macros and some functions of the
3197 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3198 be extensively tested in the future. Standard disclaimer here.
3199 Library is not automatically build yet. But one can build it by
3200 invoking 'make' inside the libc directory.
3201 * added ADC library under libio. Preliminary version yet.

3211 * (pic16_storeForReturn): optimized return of 0,
3212 * (genCmp): experimental code for new genCmp which uses PIC18's
3213 special compare&skip instructions. Initial tests fail some times
3214 with variables grater than 1 byte in size, so new code is disabled,
3215 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3217 * (genCast): began a fix to optimize the casting of a bit to another
3218 bit, now assigning a bitfield to another bitfield will fail, sorry,
3219 * src/pic16/main.c: disabled the use of lr-support feature,
3220 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

3226 * (isBankInstruction): modified to return 0 for no banking instruction,
3227 and 1 for banking instruction,
3228 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3229 caused stop processing pCodes after a inline assembly block,
3230 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
3231 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
3232 registers when it shouldn't,
3233 * src/pic16/ralloc.c (allocReg): add preliminary support for
3234 supporting a limited set of temporary registers,
3236 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3238 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
3239 genDataPointerSet): ensure assignments always copy in MSB to LSB
3241 (loadRegFromAop): recognize CLRH optimization,
3242 (genFunction): optimize RECEIVE iCodes in reentrant functions
3244 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6155 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
6157 * src/SDCCast.c: added an additional type flow in decorateType() of
6158 opposite direction, see feature request #860006; it's enabled at runtime
6159 by setting the environment variable SDCC_NEWTYPEFLOW
6160 * src/SDCCast.h: changed prototype of decorateType()
6161 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
6162 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from

6196 code / RAM are in the same page / bank. This means the linker can
6197 safely allocate code/RAM of separate ASM files to different pages/banks.
6198 * doc/sdccman.lyx: added Slade's tips

6241 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
6243 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
6244 loaded with the linker search paths (-L arguments) and the libraries
6245 to be linked with the current source (-l arguments). Changes
6246 currently will affect only the pic16 port.
6247 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6248 include path the port specific paths and port specific libraries,
6249 * gplink command now contains the $3 argument,
6250 * src/pic16/device.h,
6251 * src/pic16/device.c,: structure PIC_device is made public and
6252 renamed to PIC16_device, the same for variable Pics which is renamed

6267 Documenting changes from previous commits.
6268 * configure.in (version 1.56),
6269 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6270 when generating output files to configure the pic16 library,
6271 but now I've commented it out, since gputils aren't installed in the
6272 SF compile farm, so library won't compile
6274 * device/lib/Makefile.in (version 1.56): initially I've added in
6275 target 'all' the prerequestive 'model-pic16' so it compiled the
6276 pic16 library, but now I've commented it out for the same reasons
6278 * added targets 'model-pic16' and 'objects-pic16' to compile the
6280 * added target 'port-specific-objects-pic16' to handle the
6281 generated libraries and copy them into the build/ directory
6282 * added target 'clean-intermediate-pic16' to clean intermediate
6283 files into pic16 directory
6284 * in target 'installdirs' added line to create directory pic16 in
6285 the installation path

6288 added lines to copy all header files to installation path,
6289 * in target 'installdirs' added line create directory for pic16
6290 headers in the installation path

6305 * src/z80/main.c (_parseOptions): fixed the portmode= command line
6306 option so that it actually works. Made it specific to the z80, since
6307 the gbz80 doesn't have these kinds of I/O ports.
6309 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6311 * device/include/z180.h,

6335 via literal number. The symbol is placed in the corresponding
6336 position of the data ram
6337 * (pic16_dump_section): relocatable and absolute uninitialized
6338 data are now emitted in sorted order to reduce section naming,
6339 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
6340 weren't marked as being in the access bank,
6342 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
6344 Added portion of GNU PIC Library under the directory
6345 device/include/pic16 and device/lib/pic16. These files
6346 contain the declarations of SFRs for the PIC18Fxx2 devices.
6347 The directory is initialized via configure from toplevel.

6579 added variable stackPos,
6581 * gen.c: genCall, assignResultValue: added support for
6582 pushing/retrieving function parameters to/from stack,
6583 genFunction,genEndFunction: setup stack frame for the
6585 genAddrOf: will be changed according to bug 863624

6590 * glue.c: added variable 'externs' which holds extern symbols,
6591 pic16emitRegularMap: is modified to properly handle relocatable
6592 symbols under the new scheme,

6598 because gplink yet does not support stack and SDCC does not
6599 yet support a type of crt0.o object to create the final binary.
6601 * Removed many lines that contain 8051 legacy code.
6602 * The code is finally placed under a 'code' directive.
6603 * Added port specific options.
6605 * _process_pragma: simplified since now we do not need *special*
6606 include file to define SFR registers. But a separate header
6607 will be needed. This will be developed later.
6608 * _pic16_parseOptions: added, parses port specific options:
6609 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6610 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6611 --preplace-udata-with=
6613 * _pic16_setDefaultOptions: modified to initialize section names,
6614 but hack is temporarly out of order since it needs improvement.
6615 * _pic16_genAssemblerPreamble: configuration words are emitted by
6616 their address instead of their name. This part is incomplete and
6617 supports only the 18Fxx2 devices. Other devices will emit an error
6618 during assembly since they do not contain the same set of config
6620 * _pic16_genIVT: is modified,
6622 * pcode.c: added definitions for some hardware registers that are needed
6624 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6625 All PCI entries are updated. Now LFSR is supported.
6626 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6627 * added pic16_newpCodeOpLit2 to support instructions with
6628 two literal arguments
6629 * pic16_pCode2str: corrected code that emits assembler instructions
6630 with two literal operands and those that have an access bit modifier
6631 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6632 this fixes a bug which caused some labels to be lost, when an
6633 assembler directive was added, i.e. banksel,
6634 * pic16_FixRegisterBanking: improved logic that causes the insertion
6636 * InlineFunction: functions that are called once, are not any more
6637 inlined. This can be a port option in the future,
6639 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6641 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6642 hold the corresponding uninitialized symbols,
6643 * pic16_allocProcessorRegister: registers have explicit marked the
6645 * pic16_allocInternalRegister: registers are explicit marked as
6647 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6648 processing list, so bit registers were lost,
6651 * ralloc.h: added field 'accessBank' and original symbol operand
6652 in register definition,
6653 * removed the field isMapped from register definition,
6655 ** Several functions have been removed from various sources:
6656 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6657 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6658 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6659 pic16_assignRelocatableRegisters
6661 ** others have been introduced:
6662 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6663 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6665 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6667 * support/scripts/inc2h.pl: changed definition of BIT_AT
6668 to emit 'sbit at' instead of 'bit at'. This was a request.
6670 PIC16 port related preliminary changes:
6671 * gen.c: prefixed function popRegFromString with
6672 pic16_ and all references to it corrected
6673 * pcode.c: all pic16_pc_* hardware registers prefixed
6674 with underscore (_),
6675 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6676 * ralloc.c: newReg(): when register is REG_SFR then
6677 set address to rIdx,
6678 pic16_allocProcessorRegister(): marks register wasUsed=0
6679 pic16_writeUsedRegs(): added a call to assign processor
6680 registers via pic16_assignFixedRegisters
6682 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6684 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6685 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6686 variables in unused register banks. Also the SSEG is placed
6687 wherever there is enough space for it, and IDATA can be anywhere
6688 in internal RAM. For now compile using -Wl-Y[stack_size].
6689 The mem file is different for this option as well, since it
6690 makes no sense of talking about DSEG lenght.
6692 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6694 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6695 in certain cases, e.g. when ROM assignment, patch provided
6696 from Albert den Haan.

6937 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6939 * src/SDCCast.c (decorateType): disabled a transformation I added in
6940 revision 1.188 (access to fields of a structure at an absolute address);
6941 it breaks with bitfields, extern declarations, and gcse analysis.
6942 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
6943 could be assigned through a pointer, so don't complain.
6944 * src/SDCCast.c (astErrors),
6946 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

7048 * src/mcs51/main.c: started fixing bug #737001 (SDCC not clearing
7049 uninitialized variables) for the mcs51. Set environment variable

7051 xdata initialization slightly shorter
7053 2003-11-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7700 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
7701 fetching of the pointer
7702 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
7703 copied from genNearPointerSet()
7704 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
7705 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

7721 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7722 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7723 type for bits was changed. It resulted in bit variables becoming
7724 global, which is not permitted in PIC 14 assembly output.
7726 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

7741 A few small changes that speed up the peephole optimizer.
7745 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7747 Try to make the peephole optimizer smarter by maintaining
7748 an association between the assembly source code and the
7749 iCodes that originated them. Put this information to use
7750 with a new peephole rule condition "notVolatile" so that
7751 the rules can be aggressive yet still safe.
7756 * src/mcs51/peeph.def
7758 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7762 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7763 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7764 if the left or right operand symbols have the accuse flag set.
7766 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7768 Changed the type of the result of the ! (NOT) operator to char;
7769 previously it returned the same type as the source. This allows
7770 us to eliminate all the genFloatNot functions (all of its target
7771 implementations were very buggy) since !float can use the same

7783 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7784 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7785 during interrupts. Ensure WSAVE is located at a shared bank address.
7786 2. Fixed page selection in some places
7787 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7788 the registers name strings.
7789 4. Fixed "signed / unsigned compare" compiler warnings.
7790 5. The PIC port manages its own allocation of the general purpose
7791 registers, but makes no attempt to reuse them. As a result when
7792 compiling it soon runs out of general purpose registers. Some
7793 additional code was added to the files pcode.c and device.c to walk
7794 through the function call tree and rename the registers so that they
7804 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

7811 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7813 Made bitfield a distinct type from bit so that bitfields
7814 convert as per ANSI C and bits retain their traditional
7815 boolean style behaviour. Implemented bitfield support in
7823 * src/ds390/gen.c: bit v bitfield split
7824 * src/z80/gen.c: New support for bitfields
7825 * support/regression/tests/bitfields.c: reenabled z80,
7828 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7830 Rules 246.x, 247.x relate to bitfields, the others speed up
7831 access to xdata mapped I/O devices.
7833 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7835 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7837 Cleaned up genPackBits and genUnpackBits and added two helper
7838 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7839 for literal assignments in genPackBits (thanks to Frieder for
7845 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7847 Fixed bug #748310 (pointer to function type mishandled when the
7848 function name is omitted). Also fixed a SIGSEGV when a function
7849 attribute (reentrant, etc) is used on a non-function or on a
7850 function but misplaced before the parameter list.
7852 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
7854 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
7855 * support/Util/SDCCerr.h,

7877 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7879 Made the constant following the "interrupt" keyword optional. If
7880 omitted, the function will not automatically be given an entry
7881 in the interrupt vector table (similar to #pragma NOIV, but
7882 less syntacticly kludgy). The interrupt number is also now
7883 range checked. Also fixed a bug in the high order bit example

7897 * src/SDCCicode.c (operandOperation): rewritten some ops
7898 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
7899 * src/SDCCsymt.c (computeType): literals are handled the same way as any
7901 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
7902 be re-activated by defining REDUCE_LITERALS)
7903 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
7904 unsigned, but are signed by default
7905 * src/SDCCval.c (constVal): rearranged
7906 * src/SDCCval.c (valMod): preliminary fix
7907 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8362 Using pdflatex this will give you a hyperlinked pdf file with
8363 bookmarks. (prepend '%' before /usepackage if this breaks something)

8412 * src/SDCCmain.c: linkOptions is changed to set *,
8413 added if/endif conditional macros to remove options help
8414 messages from optionsTable when a port is not configured, added
8415 support for the PIc16 port in the ports table, when executing
8416 the compiler with no port specified on command line, a default
8417 port is selected with the new macro DEFAULT_PORT which is
8418 defined in port.h, in setDefaultOptions() linkOptions is removed
8419 from initialization assignment, since now it is a set,
8420 parseCmdLine uses setParseWithComma for linkOptions, in
8421 linkEdit() linkOptions are accessed with new function indexSet()
8422 which returns the i'th item of a set variable. See SDCCset.c, in
8423 linkEdit() when calling buildCmdLine(), added linkOptions as
8424 last argument. Now users can pass arguments to gplink via the
8425 -Wl option, main() uses pic16glue() to glue up pic16 programs

8437 * src/pic16/glue.c: commented out some error producing lines
8438 * src/pic16/main.c: __config directives are commented out to stop
8439 gpasm complaining and test the linkage with gplink, _linkCmd and
8440 _asmCmd changed to be more gplink and gpasm friendly
8441 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8442 produced an error when parsed, peep rule 12 is added to utilize
8443 movff, but it is commented out since the pCode does not support
8444 yet a command with 2 address arguments
8446 2003-05-18 <johan AT balder>
8448 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
8449 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

8473 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
8475 2003-05-11 Borut Razem <borut.razem AT siol.net>
8477 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
8478 the path of bin directory, so that PATH is the only env. variable, which has to be set
8479 in case of standard installation.
8480 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

9517 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9518 .adb instead of .cdb
9520 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9522 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9523 value from option --iram-size.
9525 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9527 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9530 2002-09-18 <wiml AT hhhh.org>
9532 * SDCClrange.h: exposed setFromRange() and setToRange()
9533 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9534 packRegsForAccUse() (bug 542397)
9535 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9536 multiple times and emitting the fetch operations more than once
9537 added aopGetUsesAcc() function to allow binary operators to
9538 fetch their operands in the correct order; made genMinus() emit
9539 compact code for X = LITERAL - Y
9541 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9542 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9543 sprintf() in line 1267.
9545 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9546 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9549 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9550 Changes to aslink (All the changes are marked with 'JCF'):
9552 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9555 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9556 area BSEG. Also moves, if possible, the DATA area down into the internal
9557 ram so more space is available.
9559 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9562 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9563 not bytes. Function summary() which creates a memory usage summary
9564 file with extension .mem. Reports of overlaping stack and small stack
9565 size. If the space for the stack is less than 16 bytes aslink trows a
9568 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9569 the 8051. Option 'y' for memory summary output file.
9571 Changes to sdcc (All the changes are marked with 'JCF'):
9573 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9575 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9576 overlaying area for it (uses RegBankUsed[4]).
9578 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9579 bank zero as used by default. By default aslink locates the stack
9580 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9581 the creation of the .mem file. Delegates the allocation of data area
9582 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9583 the begining of the stack area to aslink.
9585 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9586 glue() in SDCCglue.c creates an area for it.
9588 2002-09-03 Borut Razem <borut.razem AT siol.net>
9589 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9590 sdcc/src/pic/glue.c:
9591 introduced atexit() handler for teporay files removal in case of
9592 errors, assertions, ...
9594 2002-08-29 Borut Razem <borut.razem AT siol.net>
9595 * sdcc/support/cpp2/auto-host_vc_in.h:
9596 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9597 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9598 Maybe there is a similar problem with BORLANDC? It should be checked!
9600 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9601 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9602 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9603 was not executed, and the compiler (cl) launched a warning:
9604 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9606 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9607 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9609 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9610 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9612 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9613 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9614 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9615 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9616 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9617 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9618 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9619 - added Release configuration in VS projects
9620 - review of compiler an linker options
9621 - VC .exe files are generated in bin_vc directory, not to interfere
9622 with binaries generated from other projects (cygwin, mingw, bcc ...)
9624 * sdcc/src/yacc.dsp: added
9626 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9627 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9628 and insert the version number definitions from .version
9630 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9632 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9633 added - genarate auto-host.h using auto-host_vc_in.h as template
9636 removed from CVS, generated automatically
9638 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9639 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9641 2002-08-11 Borut Razem <borut.razem AT siol.net>
9642 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9644 2002-08-10 Borut Razem <borut.razem AT siol.net>
9645 * src/SDCCmain.c (main):
9646 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9647 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9648 The consequence was that some temporary files were not removed.
9651 unification of code in functions tempfilename() and tempfile():
9652 function tempnam() is defined in Visual Studio 6.0 and .NET
9654 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9656 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9657 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9658 - removed compiler command line option /WX: Treats all warnings as errors
9659 - update a list of source files, included into the project
9661 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9662 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9663 changed project type to Generic Project so that can be correcly converted to VS.NET project
9665 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9667 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9669 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9671 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9672 added return 0 statements after assert() to make compiler happy
9674 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9675 added newline in the def file to keep MSC compiler satisfied
9677 * sdcc/src/z80/gen.c:
9678 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9679 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9680 - solved MSC error in function aopDump()
9682 * sdcc_vc.h: define PREFIX as "\\sdcc"
9684 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9685 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

9724 2002-03-28 Johan Knol <johan AT balder>
9726 * src/SDCCval.c: fixed bug #532436
9728 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9730 Added "char *Processor" field to the port structure.
9733 Added -p option. Allows port dependent processor to be specified.
9736 Initialized the new field char *Processor field to NULL in all ports
9739 Compiler generated registers for interrupt context saving
9740 were not getting allocated.
9742 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9745 Fixed left shift. Will promote the left side of a left shift
9746 if a) left shifting more than size of operand or b) when assigned
9747 to something size > size of left side
9749 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9751 tons of changes. Register allocation has been
9752 rewritten. Added customization for the various PICs. Flow
9753 analysis is restructured. ...

9857 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
9859 * sdcc/src/SDCCloop.c:
9860 Previous fix was not good. basic blocks that have "break" or "return" are
9861 not really partof a loop , but live ranges used in these blocks should
9862 be live thru the entire loop, so set partOfLoop but don't add them to
9865 2002-02-21 <johan AT FRIJA>
9867 * src/SDCCcse.c: fixed bug #514308
9869 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
9872 Fixed BUG #519583. If a conditional block ended in a return/break
9873 statement inside a loop, it was not being considered part of the loop.
9875 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
9877 2002-02-10 Karl Bongers <karl AT turbobit.com>
9880 Fixed up SDCDB debugger somewhat. Updated debugger/README
9881 with lots of comments and notes.
9883 * device/examples/test2.c:
9884 Fix bug, "red" variable not being initialized(compiler complained).
9886 * device/examples/Makefile, examples/test3.c:
9887 Add Makefile in device/examples folder, compiles test3.c
9888 for use as a multiple module SDCDB test case.
9890 * sim/ucsim/cmd.src/cmdset.cc:
9891 Took out debug printfs in ucsim "next" command.
9894 Karl and Johan start ucsim XA support. Most dissassembly working,
9895 about 75% emulation done(plenty of work remaining).
9897 * sim/ucsim/z80.src:
9898 Add Z80 support to ucsim, add test-ucz80 regression test,
9899 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.

9935 set preprocessor defines (depending on options)
9937 * src/SDCCicode.c, src/SDCCicode.h:
9938 changes made to handle multiple sends & receives
9941 Added options --protect-sp-update (ds390) and --parms-in-bank1 (ds390/mcs51)
