1 2006-03-07 Maarten Brock <sourceforge.brock AT dse.nl>
3 * device/include/mcs51/c8051f410.h: new SiLabs mcu
4 * src/ds390/peeph.def: disabled 186.d and 227.a as fix for #1434401
5 * support/regression/tests/array.c: added parenthesis, made arrays unsigned
7 2006-03-06 Borut Razem <borut.razem AT siol.net>
9 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
12 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
14 * src/pic16/gen.c (genPcall): fixed bug #1443644
15 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
16 which dumps before the function entry point a data byte which represents
17 the number of the local variables used by the specified function, added
18 'xinst' for initial support for Extended Instruction Support,
19 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
20 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
21 port->fun_prefix anymore (may change later),
22 (genFunction, genEndFunction): do not store/restore local registers for
23 _main (this should take care the --main-return command line option in
25 (genOr): removed some legacy pic-port instructions,
26 * src/pic16/genarith.c (genAddLit): re-enabled old code because
27 performing operations with SFR's causes data to be written more than
28 once to each SFR. Perhaps SFRs should be handled in special cases...
29 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
31 * src/pic16/main.c (_process_pragma): stack bound checking did not take
32 into account for stack starting position,
33 (struct OPTIONS pic16_optionsTable): added command line argument
34 --extended or -y for Extended Instruction Support,
35 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
36 (deassignLRs): *** perhaps the most important change, old 'for' code
37 (commented out for reference), didn't account for some registers which
38 were left marked 'not free' after a pointer operation. The change
39 reduces register usage a lot in some cases

2314 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
2315 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
2316 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
2317 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
2318 always available in leading double underscore form. The C99 support is
2319 mostly missing, but it's a start.
2320 * support/regression/tests/bug-227710.c: fixed nonconforming use of

2399 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2401 * device/lib/printf_large.c: removed inline assembly for portability and
2402 readability. Use printf_fast if speed or size are more important.
2403 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2404 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2406 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2408 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2409 prevent compiler warning
2411 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2413 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2414 moved to level 0 and declared as static. Also they are explicit
2415 placed in access bank. This was necessery because some times they
2416 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2417 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2418 optimizations. Currently only compare to unsigned char is implemented,
2419 * src/pic16/gen.c: added fReturnIdx array,
2420 * (struct resolvedIfx) is moved to gen.h and made public,
2421 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2422 * (aopForSym): added an optimization to directly store in stack of
2423 the operand of a SEND iCode,
2424 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2425 but as registers instead (AOP_REG) using the fReturnIdx array,
2426 * (pic16_freeAsmop): remove the freed register from the
2427 _G.sregsAlloc field,
2428 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2429 a compare of 'WREG',
2430 * (pic16_popGetTempRegCond): changed function prototype, now
2431 function takes also a bitVector argument v which holds the current
2432 set of registers that are allocated for stack access by aopForSym,
2433 registers allocated in aopForSym for accessing stack symbols are not
2434 any more part of the functions usedRegs field,
2435 * (genCall): some times aopOp is called for a stack variable to be
2436 send, aopForSym might perform the push, if this is true make sure
2437 that genCall doesn't push the variable twice by testing _G.resDirect,
2438 * (genFunction): changed testing for unspecified interrupt number
2439 from 256 to INTNO_UNSPEC,
2440 * modified selection scheme of frame pointer generation. Previously
2441 if function did use local registers a frame pointer was generated,
2442 now a frame pointer is generated only if function has arguments
2443 (that need PLUSW2 register access), or has stack arguments, or the
2444 compiler is not instructed to omit the frame pointer,
2445 * (genEndFunction): before restoring local registers that were saved
2446 in the function preamble, also restore the registers that *might*
2447 have been allocated for stack access,
2448 * (genRet): removed some old comments,
2449 * (genCmp, the active (RN's) version): added a call to the
2450 pic16_genCmp_special function to perform the compare with a more
2451 robust and optimized way,
2452 * (genInline): a feature has been added in inline code generation,
2453 which allows a wildcard variable substitution when writing inline
2454 assembly. Code is incomplete and experimental therefore undocumented,
2455 * (genCast): changed order of aopOp for result and right to allow
2456 aopForSym to directly load the result if possible,
2457 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2458 perform an optimized compare on some selected special occasions,
2459 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2460 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2461 generate an IVT any more,
2462 * src/pic16/main.c (pic16_optionsTable): added command line option
2464 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2465 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2467 * src/pic16/NOTES: Raphael Neider added in list of active developers
2468 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2469 jumptable_end to prevent bug #,
2470 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2471 inCond and outCond fields,
2472 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2473 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2474 turn off register spilling,
2475 * (packRegsForOneUse): synced with other ports' versions although it
2476 is not used currently,
2477 * (pic16_packRegisters): added an optimization while reading
2478 structure bitfields, some registers may be saved (malloc code is
2479 decreased by 80 bytes)
2481 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2483 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2484 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2485 this can be optimized more?
2487 2005-03-10 Raphael Neider <rneider AT web.de>
2489 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2490 genNearPointerGet): (hopefully) fixed access to bitfields via
2491 pointers (p->bitN = x; and x = p->bitN; failed)
2493 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

3125 Adding support for replacing ljmps with sjmps in jumptables
3126 generated for switch statements. For now you need to set the
3127 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3128 Now 4 algorithms for mcs51 jumptable generation are used:
3129 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
3130 addresses loaded pc-relative for up to 112 cases and stack-pushing
3131 target addresses loaded with offset from dptr for up to 256 cases.

3161 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3163 * added libc directory. The current version of LibC contains string
3164 functions, ctype functions and macros and some functions of the
3165 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3166 be extensively tested in the future. Standard disclaimer here.
3167 Library is not automatically build yet. But one can build it by
3168 invoking 'make' inside the libc directory.
3169 * added ADC library under libio. Preliminary version yet.

3179 * (pic16_storeForReturn): optimized return of 0,
3180 * (genCmp): experimental code for new genCmp which uses PIC18's
3181 special compare&skip instructions. Initial tests fail some times
3182 with variables grater than 1 byte in size, so new code is disabled,
3183 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3185 * (genCast): began a fix to optimize the casting of a bit to another
3186 bit, now assigning a bitfield to another bitfield will fail, sorry,
3187 * src/pic16/main.c: disabled the use of lr-support feature,
3188 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

3191 bits with offset (case PO_GPR_BIT),
3192 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
3194 * (isBankInstruction): modified to return 0 for no banking instruction,
3195 and 1 for banking instruction,
3196 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3197 caused stop processing pCodes after a inline assembly block,
3198 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

3200 registers when it shouldn't,
3201 * src/pic16/ralloc.c (allocReg): add preliminary support for
3202 supporting a limited set of temporary registers,
3204 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3206 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,

3210 (genFunction): optimize RECEIVE iCodes in reentrant functions
3212 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3214 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

6115 * support/regression/generate-cases.py (main): Changed from inline
6118 * doc/Makefile (install): Changed to depth first to get rid of
6119 missing directory install warning.
6121 * as/Makefile (install-doc): Made work on Mac.
6123 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
6125 * src/SDCCast.c: added an additional type flow in decorateType() of
6126 opposite direction, see feature request #860006; it's enabled at runtime
6127 by setting the environment variable SDCC_NEWTYPEFLOW
6128 * src/SDCCast.h: changed prototype of decorateType()
6129 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
6130 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
6131 'char' to 'int' can be omitted, if both operands are 'unsigned char';
6132 see feature request #877103
6133 * src/SDCCval.c: updated call of decorateType()
6134 (valBitwise): fixed bug #882876
6135 (valMinus): added promotion
6136 (valLogicAndOr): result is unsigned
6137 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
6138 * src/SDCCsymt.c (computeType),
6139 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'
6140 must not cause an unsigned operation
6141 * src/pic/glue (pic14emitRegularMap),
6142 * src/pic16/glue.c (pic16emitRegularMap): updated call of decorateType()
6144 2004-01-23 Bernhard Held <bernhard AT bernhardheld.de>

6161 * src/pic/ralloc.h: applied patch from Slade Rich;
6162 added support for multiple code pages and multiple RAM banks on the
6163 PIC 14 port. The ASM files now no longer simply assume all the
6164 code / RAM are in the same page / bank. This means the linker can
6165 safely allocate code/RAM of separate ASM files to different pages/banks.
6166 * doc/sdccman.lyx: added Slade's tips
6167 * src/mcs51/peeph.def: fixed bug #880768

6176 * sim/ucsim/gui.src/serio.src/main.cc: Fixed unconditional use of
6179 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
6180 strtof is not part of C89 and isn't included with Mac OS X.
6182 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6184 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

6209 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
6211 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
6212 loaded with the linker search paths (-L arguments) and the libraries
6213 to be linked with the current source (-l arguments). Changes
6214 currently will affect only the pic16 port.
6215 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6216 include path the port specific paths and port specific libraries,
6217 * gplink command now contains the $3 argument,
6218 * src/pic16/device.h,
6219 * src/pic16/device.c,: structure PIC_device is made public and
6220 renamed to PIC16_device, the same for variable Pics which is renamed

6235 Documenting changes from previous commits.
6236 * configure.in (version 1.56),
6237 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6238 when generating output files to configure the pic16 library,
6239 but now I've commented it out, since gputils aren't installed in the
6240 SF compile farm, so library won't compile
6242 * device/lib/Makefile.in (version 1.56): initially I've added in
6243 target 'all' the prerequestive 'model-pic16' so it compiled the
6244 pic16 library, but now I've commented it out for the same reasons
6246 * added targets 'model-pic16' and 'objects-pic16' to compile the
6248 * added target 'port-specific-objects-pic16' to handle the
6249 generated libraries and copy them into the build/ directory
6250 * added target 'clean-intermediate-pic16' to clean intermediate
6251 files into pic16 directory
6252 * in target 'installdirs' added line to create directory pic16 in
6253 the installation path
6255 * device/include/Makefile.in (version 1.11): in target 'install'
6256 added lines to copy all header files to installation path,
6257 * in target 'installdirs' added line create directory for pic16
6258 headers in the installation path

6273 * src/z80/main.c (_parseOptions): fixed the portmode= command line
6274 option so that it actually works. Made it specific to the z80, since
6275 the gbz80 doesn't have these kinds of I/O ports.
6277 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6279 * device/include/z180.h,

6301 Mainly changes to support compilation of the device libraries
6302 * src/pic16/device.c: stack is allocated via symbol and not
6303 via literal number. The symbol is placed in the corresponding
6304 position of the data ram
6305 * (pic16_dump_section): relocatable and absolute uninitialized
6306 data are now emitted in sorted order to reduce section naming,
6307 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
6308 weren't marked as being in the access bank,
6310 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
6312 Added portion of GNU PIC Library under the directory
6313 device/include/pic16 and device/lib/pic16. These files
6314 contain the declarations of SFRs for the PIC18Fxx2 devices.
6315 The directory is initialized via configure from toplevel.
6317 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
6319 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

6344 * doc/sdccman.lyx: Moved and added some sections, small changes
6345 all over. Telling LaTeX to be less strict with word spacing
6346 to better keep the right margin. Changed some notes about
6347 maintainance of the ports in section 3.2.1 - is it OK like this?
6349 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

6389 * src/pic16/peeph.def: all peepholes with movff are commented out,
6390 because there is a problem in the pcode peep optimizer,
6391 * src/pic16/ralloc.c: the register allocator can now reuse local

6530 Bug reported from Jesus Calvino-Fraga
6532 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6534 * sdcc.spec: updated
6535 * device/include/Makefile.in: don't install CVS directories

6543 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6545 PIC16 port related changes:
6546 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6547 added variable stackPos,
6549 * gen.c: genCall, assignResultValue: added support for
6550 pushing/retrieving function parameters to/from stack,
6551 genFunction,genEndFunction: setup stack frame for the
6553 genAddrOf: will be changed according to bug 863624
6555 * added files genutils.c and genutils.h which contain gen*
6556 debugged and optimised functions extracted from gen.c
6558 * glue.c: added variable 'externs' which holds extern symbols,
6559 pic16emitRegularMap: is modified to properly handle relocatable
6560 symbols under the new scheme,
6561 pic16createInterruptVect: is modified
6562 pic16printPublics: is modified to emit 'global' assembler directives,
6563 added pic16_printExterns to print extern symbols,
6564 pic16glue: initializes stack/frame pointer in the beginning of
6565 the assembly output. Temporary hack, will be corrected later,
6566 because gplink yet does not support stack and SDCC does not
6567 yet support a type of crt0.o object to create the final binary.
6569 * Removed many lines that contain 8051 legacy code.
6570 * The code is finally placed under a 'code' directive.
6571 * Added port specific options.
6573 * _process_pragma: simplified since now we do not need *special*
6574 include file to define SFR registers. But a separate header
6575 will be needed. This will be developed later.
6576 * _pic16_parseOptions: added, parses port specific options:
6577 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6578 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6579 --preplace-udata-with=
6581 * _pic16_setDefaultOptions: modified to initialize section names,
6582 but hack is temporarly out of order since it needs improvement.
6583 * _pic16_genAssemblerPreamble: configuration words are emitted by
6584 their address instead of their name. This part is incomplete and
6585 supports only the 18Fxx2 devices. Other devices will emit an error
6586 during assembly since they do not contain the same set of config
6588 * _pic16_genIVT: is modified,
6590 * pcode.c: added definitions for some hardware registers that are needed
6592 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6593 All PCI entries are updated. Now LFSR is supported.
6594 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6595 * added pic16_newpCodeOpLit2 to support instructions with
6596 two literal arguments
6597 * pic16_pCode2str: corrected code that emits assembler instructions
6598 with two literal operands and those that have an access bit modifier
6599 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6600 this fixes a bug which caused some labels to be lost, when an
6601 assembler directive was added, i.e. banksel,
6602 * pic16_FixRegisterBanking: improved logic that causes the insertion
6604 * InlineFunction: functions that are called once, are not any more
6605 inlined. This can be a port option in the future,
6607 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6609 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6610 hold the corresponding uninitialized symbols,
6611 * pic16_allocProcessorRegister: registers have explicit marked the
6613 * pic16_allocInternalRegister: registers are explicit marked as
6615 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6616 processing list, so bit registers were lost,
6619 * ralloc.h: added field 'accessBank' and original symbol operand
6620 in register definition,
6621 * removed the field isMapped from register definition,
6623 ** Several functions have been removed from various sources:
6624 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6625 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6626 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6627 pic16_assignRelocatableRegisters
6629 ** others have been introduced:
6630 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6631 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6633 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6635 * support/scripts/inc2h.pl: changed definition of BIT_AT
6636 to emit 'sbit at' instead of 'bit at'. This was a request.
6638 PIC16 port related preliminary changes:
6639 * gen.c: prefixed function popRegFromString with
6640 pic16_ and all references to it corrected
6641 * pcode.c: all pic16_pc_* hardware registers prefixed
6642 with underscore (_),
6643 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6644 * ralloc.c: newReg(): when register is REG_SFR then
6645 set address to rIdx,
6646 pic16_allocProcessorRegister(): marks register wasUsed=0
6647 pic16_writeUsedRegs(): added a call to assign processor
6648 registers via pic16_assignFixedRegisters
6650 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6652 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6653 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6654 variables in unused register banks. Also the SSEG is placed
6655 wherever there is enough space for it, and IDATA can be anywhere
6656 in internal RAM. For now compile using -Wl-Y[stack_size].
6657 The mem file is different for this option as well, since it
6658 makes no sense of talking about DSEG lenght.
6660 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6662 * src/SDCClrange.c: fixed bug 869095 that caused segfault

6907 * src/SDCCast.c (decorateType): disabled a transformation I added in
6908 revision 1.188 (access to fields of a structure at an absolute address);
6909 it breaks with bitfields, extern declarations, and gcse analysis.
6910 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
6911 could be assigned through a pointer, so don't complain.

7668 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
7669 fetching of the pointer
7670 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
7671 copied from genNearPointerSet()
7672 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
7673 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

7687 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
7689 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7690 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7691 type for bits was changed. It resulted in bit variables becoming
7692 global, which is not permitted in PIC 14 assembly output.
7694 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7696 * doc/sdccman.lyx: various additions and updates. Rearranged sections
7698 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7700 Z80 and MCS51 linkers complaint if a public symbol is defined
7701 in more than one library module:

7707 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7709 A few small changes that speed up the peephole optimizer.
7713 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7715 Try to make the peephole optimizer smarter by maintaining
7716 an association between the assembly source code and the
7717 iCodes that originated them. Put this information to use
7718 with a new peephole rule condition "notVolatile" so that
7719 the rules can be aggressive yet still safe.
7724 * src/mcs51/peeph.def
7726 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7730 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7731 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7732 if the left or right operand symbols have the accuse flag set.
7734 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7736 Changed the type of the result of the ! (NOT) operator to char;
7737 previously it returned the same type as the source. This allows
7738 us to eliminate all the genFloatNot functions (all of its target
7739 implementations were very buggy) since !float can use the same
7742 * src/SDCCicode.c (ast2iCode): ! returns char
7743 * src/mcs51/gen.c (genNot, genNotFloat),
7744 * src/ds390/gen.c (genNot, genNotFloat),
7745 * src/z80/gen.c (genNot, genNotFloat),
7746 * src/pic/gen.c (genNot, genNotFloat),
7747 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
7749 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
7751 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7752 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7753 during interrupts. Ensure WSAVE is located at a shared bank address.
7754 2. Fixed page selection in some places
7755 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7756 the registers name strings.
7757 4. Fixed "signed / unsigned compare" compiler warnings.
7758 5. The PIC port manages its own allocation of the general purpose
7759 registers, but makes no attempt to reuse them. As a result when
7760 compiling it soon runs out of general purpose registers. Some
7761 additional code was added to the files pcode.c and device.c to walk
7762 through the function call tree and rename the registers so that they
7772 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
7773 genPlus() & genMinus() when the result is the same as left or right

7779 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7781 Made bitfield a distinct type from bit so that bitfields
7782 convert as per ANSI C and bits retain their traditional
7783 boolean style behaviour. Implemented bitfield support in
7791 * src/ds390/gen.c: bit v bitfield split
7792 * src/z80/gen.c: New support for bitfields
7793 * support/regression/tests/bitfields.c: reenabled z80,
7796 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7798 Rules 246.x, 247.x relate to bitfields, the others speed up
7799 access to xdata mapped I/O devices.
7801 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7803 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7805 Cleaned up genPackBits and genUnpackBits and added two helper
7806 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7807 for literal assignments in genPackBits (thanks to Frieder for
7813 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7815 Fixed bug #748310 (pointer to function type mishandled when the
7816 function name is omitted). Also fixed a SIGSEGV when a function
7817 attribute (reentrant, etc) is used on a non-function or on a
7818 function but misplaced before the parameter list.
7820 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
7822 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
7823 * support/Util/SDCCerr.h,

7845 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7847 Made the constant following the "interrupt" keyword optional. If
7848 omitted, the function will not automatically be given an entry
7849 in the interrupt vector table (similar to #pragma NOIV, but
7850 less syntacticly kludgy). The interrupt number is also now
7851 range checked. Also fixed a bug in the high order bit example
7858 * support/Util/SDCCerr.c
7859 * support/Util/SDCCerr.h
7862 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
7864 * src/SDCCcse.c (algebraicOpts): fix bug converting op from value to type
7865 * src/SDCCicode.c (operandOperation): rewritten some ops
7866 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
7867 * src/SDCCsymt.c (computeType): literals are handled the same way as any
7869 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
7870 be re-activated by defining REDUCE_LITERALS)
7871 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
7872 unsigned, but are signed by default
7873 * src/SDCCval.c (constVal): rearranged
7874 * src/SDCCval.c (valMod): preliminary fix
7875 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8327 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
8328 the regression tests I'm not brave enough to enable 245.b, 245.c

8330 Using pdflatex this will give you a hyperlinked pdf file with
8331 bookmarks. (prepend '%' before /usepackage if this breaks something)

8380 * src/SDCCmain.c: linkOptions is changed to set *,
8381 added if/endif conditional macros to remove options help
8382 messages from optionsTable when a port is not configured, added
8383 support for the PIc16 port in the ports table, when executing
8384 the compiler with no port specified on command line, a default
8385 port is selected with the new macro DEFAULT_PORT which is
8386 defined in port.h, in setDefaultOptions() linkOptions is removed
8387 from initialization assignment, since now it is a set,
8388 parseCmdLine uses setParseWithComma for linkOptions, in
8389 linkEdit() linkOptions are accessed with new function indexSet()
8390 which returns the i'th item of a set variable. See SDCCset.c, in
8391 linkEdit() when calling buildCmdLine(), added linkOptions as
8392 last argument. Now users can pass arguments to gplink via the
8393 -Wl option, main() uses pic16glue() to glue up pic16 programs

8405 * src/pic16/glue.c: commented out some error producing lines
8406 * src/pic16/main.c: __config directives are commented out to stop
8407 gpasm complaining and test the linkage with gplink, _linkCmd and
8408 _asmCmd changed to be more gplink and gpasm friendly
8409 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8410 produced an error when parsed, peep rule 12 is added to utilize
8411 movff, but it is commented out since the pCode does not support
8412 yet a command with 2 address arguments
8414 2003-05-18 <johan AT balder>
8416 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

8443 2003-05-11 Borut Razem <borut.razem AT siol.net>
8445 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
8446 the path of bin directory, so that PATH is the only env. variable, which has to be set
8447 in case of standard installation.
8448 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

9530 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9531 not bytes. Function summary() which creates a memory usage summary
9532 file with extension .mem. Reports of overlaping stack and small stack
9533 size. If the space for the stack is less than 16 bytes aslink trows a
9536 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9537 the 8051. Option 'y' for memory summary output file.
9539 Changes to sdcc (All the changes are marked with 'JCF'):
9541 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9543 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9544 overlaying area for it (uses RegBankUsed[4]).
9546 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9547 bank zero as used by default. By default aslink locates the stack
9548 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9549 the creation of the .mem file. Delegates the allocation of data area
9550 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9551 the begining of the stack area to aslink.
9553 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9554 glue() in SDCCglue.c creates an area for it.
9556 2002-09-03 Borut Razem <borut.razem AT siol.net>
9557 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9558 sdcc/src/pic/glue.c:
9559 introduced atexit() handler for teporay files removal in case of
9560 errors, assertions, ...
9562 2002-08-29 Borut Razem <borut.razem AT siol.net>
9563 * sdcc/support/cpp2/auto-host_vc_in.h:
9564 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9565 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9566 Maybe there is a similar problem with BORLANDC? It should be checked!
9568 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9569 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9570 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9571 was not executed, and the compiler (cl) launched a warning:
9572 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9574 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9575 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9577 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9578 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9580 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9581 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9582 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9583 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9584 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9585 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9586 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9587 - added Release configuration in VS projects
9588 - review of compiler an linker options
9589 - VC .exe files are generated in bin_vc directory, not to interfere
9590 with binaries generated from other projects (cygwin, mingw, bcc ...)
9592 * sdcc/src/yacc.dsp: added
9594 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9595 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9596 and insert the version number definitions from .version
9598 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9600 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9601 added - genarate auto-host.h using auto-host_vc_in.h as template
9604 removed from CVS, generated automatically
9606 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9607 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9609 2002-08-11 Borut Razem <borut.razem AT siol.net>
9610 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9612 2002-08-10 Borut Razem <borut.razem AT siol.net>
9613 * src/SDCCmain.c (main):
9614 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9615 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9616 The consequence was that some temporary files were not removed.
9619 unification of code in functions tempfilename() and tempfile():
9620 function tempnam() is defined in Visual Studio 6.0 and .NET
9622 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9624 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9625 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9626 - removed compiler command line option /WX: Treats all warnings as errors
9627 - update a list of source files, included into the project
9629 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9630 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9631 changed project type to Generic Project so that can be correcly converted to VS.NET project
9633 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9635 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9637 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9639 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9640 added return 0 statements after assert() to make compiler happy
9642 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9643 added newline in the def file to keep MSC compiler satisfied
9645 * sdcc/src/z80/gen.c:
9646 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9647 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9648 - solved MSC error in function aopDump()
9650 * sdcc_vc.h: define PREFIX as "\\sdcc"
9652 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9653 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

9701 Added -p option. Allows port dependent processor to be specified.
9704 Initialized the new field char *Processor field to NULL in all ports
9707 Compiler generated registers for interrupt context saving
9708 were not getting allocated.
9710 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9713 Fixed left shift. Will promote the left side of a left shift
9714 if a) left shifting more than size of operand or b) when assigned
9715 to something size > size of left side
9717 2002-03-14 Scott Dattalo <scott AT dattalo.com>

9825 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
9827 * sdcc/src/SDCCloop.c:
9828 Previous fix was not good. basic blocks that have "break" or "return" are
9829 not really partof a loop , but live ranges used in these blocks should
9830 be live thru the entire loop, so set partOfLoop but don't add them to
9833 2002-02-21 <johan AT FRIJA>
9835 * src/SDCCcse.c: fixed bug #514308
9837 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>

9841 statement inside a loop, it was not being considered part of the loop.
9843 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
9845 2002-02-10 Karl Bongers <karl AT turbobit.com>
9848 Fixed up SDCDB debugger somewhat. Updated debugger/README
9849 with lots of comments and notes.
