1 2006-03-06 Borut Razem <borut.razem AT siol.net>
3 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
6 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
8 * src/pic16/gen.c (genPcall): fixed bug #1443644
9 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
10 which dumps before the function entry point a data byte which represents
11 the number of the local variables used by the specified function, added
12 'xinst' for initial support for Extended Instruction Support,
13 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
14 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
15 port->fun_prefix anymore (may change later),
16 (genFunction, genEndFunction): do not store/restore local registers for
17 _main (this should take care the --main-return command line option in
19 (genOr): removed some legacy pic-port instructions,
20 * src/pic16/genarith.c (genAddLit): re-enabled old code because
21 performing operations with SFR's causes data to be written more than
22 once to each SFR. Perhaps SFRs should be handled in special cases...
23 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
25 * src/pic16/main.c (_process_pragma): stack bound checking did not take
26 into account for stack starting position,
27 (struct OPTIONS pic16_optionsTable): added command line argument
28 --extended or -y for Extended Instruction Support,
29 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
30 (deassignLRs): *** perhaps the most important change, old 'for' code
31 (comented out for reference), didn't account for some registers which
32 were left marked 'not free' after a pointer operation. The change
33 reduces register usage a lot in some cases

2309 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
2310 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
2311 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
2312 always available in leading double underscore form. The C99 support is
2313 mostly missing, but it's a start.
2314 * support/regression/tests/bug-227710.c: fixed nonconforming use of

2393 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2395 * device/lib/printf_large.c: removed inline assembly for portability and
2396 readability. Use printf_fast if speed or size are more important.
2397 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2398 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2400 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2402 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2403 prevent compiler warning
2405 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2407 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2408 moved to level 0 and declared as static. Also they are explicit
2409 placed in access bank. This was necessery because some times they
2410 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2411 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2412 optimizations. Currently only compare to unsigned char is implemented,
2413 * src/pic16/gen.c: added fReturnIdx array,
2414 * (struct resolvedIfx) is moved to gen.h and made public,
2415 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2416 * (aopForSym): added an optimization to directly store in stack of
2417 the operand of a SEND iCode,
2418 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2419 but as registers instead (AOP_REG) using the fReturnIdx array,
2420 * (pic16_freeAsmop): remove the freed register from the
2421 _G.sregsAlloc field,
2422 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2423 a compare of 'WREG',
2424 * (pic16_popGetTempRegCond): changed function prototype, now
2425 function takes also a bitVector argument v which holds the current
2426 set of registers that are allocated for stack access by aopForSym,
2427 registers allocated in aopForSym for accessing stack symbols are not
2428 any more part of the functions usedRegs field,
2429 * (genCall): some times aopOp is called for a stack variable to be
2430 send, aopForSym might perform the push, if this is true make sure
2431 that genCall doesn't push the variable twice by testing _G.resDirect,
2432 * (genFunction): changed testing for unspecified interrupt number
2433 from 256 to INTNO_UNSPEC,
2434 * modified selection scheme of frame pointer generation. Previously
2435 if function did use local registers a frame pointer was generated,
2436 now a frame pointer is generated only if function has arguments
2437 (that need PLUSW2 register access), or has stack arguments, or the
2438 compiler is not instructed to omit the frame pointer,
2439 * (genEndFunction): before restoring local registers that were saved
2440 in the function preamble, also restore the registers that *might*
2441 have been allocated for stack access,
2442 * (genRet): removed some old comments,
2443 * (genCmp, the active (RN's) version): added a call to the
2444 pic16_genCmp_special function to perform the compare with a more
2445 robust and optimized way,
2446 * (genInline): a feature has been added in inline code generation,
2447 which allows a wildcard variable substitution when writing inline
2448 assembly. Code is incomplete and experimental therefore undocumented,
2449 * (genCast): changed order of aopOp for result and right to allow
2450 aopForSym to directly load the result if possible,
2451 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2452 perform an optimized compare on some selected special occasions,
2453 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2454 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2455 generate an IVT any more,
2456 * src/pic16/main.c (pic16_optionsTable): added command line option
2458 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2459 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2461 * src/pic16/NOTES: Raphael Neider added in list of active developers
2462 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2463 jumptable_end to prevent bug #,
2464 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2465 inCond and outCond fields,
2466 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2467 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2468 turn off register spilling,
2469 * (packRegsForOneUse): synced with other ports' versions although it
2470 is not used currently,
2471 * (pic16_packRegisters): added an optimization while reading
2472 structure bitfields, some registers may be saved (malloc code is
2473 decreased by 80 bytes)
2475 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2477 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2478 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2479 this can be optimized more?
2481 2005-03-10 Raphael Neider <rneider AT web.de>
2483 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2484 genNearPointerGet): (hopefully) fixed access to bitfields via
2485 pointers (p->bitN = x; and x = p->bitN; failed)
2487 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

3119 Adding support for replacing ljmps with sjmps in jumptables
3120 generated for switch statements. For now you need to set the
3121 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3122 Now 4 algorithms for mcs51 jumptable generation are used:
3123 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
3124 addresses loaded pc-relative for up to 112 cases and stack-pushing
3125 target addresses loaded with offset from dptr for up to 256 cases.

3155 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3157 * added libc directory. The current version of LibC contains string
3158 functions, ctype functions and macros and some functions of the
3159 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3160 be extensively tested in the future. Standard disclaimer here.
3161 Library is not automatically build yet. But one can build it by
3162 invoking 'make' inside the libc directory.
3163 * added ADC library under libio. Preliminary version yet.

3173 * (pic16_storeForReturn): optimized return of 0,
3174 * (genCmp): experimental code for new genCmp which uses PIC18's
3175 special compare&skip instructions. Initial tests fail some times
3176 with variables grater than 1 byte in size, so new code is disabled,
3177 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3179 * (genCast): began a fix to optimize the casting of a bit to another
3180 bit, now assigning a bitfield to another bitfield will fail, sorry,
3181 * src/pic16/main.c: disabled the use of lr-support feature,
3182 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

3185 bits with offset (case PO_GPR_BIT),
3186 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
3188 * (isBankInstruction): modified to return 0 for no banking instruction,
3189 and 1 for banking instruction,
3190 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3191 caused stop processing pCodes after a inline assembly block,
3192 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

3194 registers when it shouldn't,
3195 * src/pic16/ralloc.c (allocReg): add preliminary support for
3196 supporting a limited set of temporary registers,
3198 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3200 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,

6119 * src/SDCCast.c: added an additional type flow in decorateType() of
6120 opposite direction, see feature request #860006; it's enabled at runtime
6121 by setting the environment variable SDCC_NEWTYPEFLOW
6122 * src/SDCCast.h: changed prototype of decorateType()
6123 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
6124 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
6125 'char' to 'int' can be omitted, if both operands are 'unsigned char';
6126 see feature request #877103
6127 * src/SDCCval.c: updated call of decorateType()
6128 (valBitwise): fixed bug #882876
6129 (valMinus): added promotion
6130 (valLogicAndOr): result is unsigned
6131 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
6132 * src/SDCCsymt.c (computeType),
6133 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'
6134 must not cause an unsigned operation
6135 * src/pic/glue (pic14emitRegularMap),
6136 * src/pic16/glue.c (pic16emitRegularMap): updated call of decorateType()
6138 2004-01-23 Bernhard Held <bernhard AT bernhardheld.de>
6140 * src/pic/pcode.c (PCodeID): commented out left over debug code
6142 2004-01-20 Bernhard Held <bernhard AT bernhardheld.de>

6153 * src/pic/pcoderegs.c,
6155 * src/pic/ralloc.h: applied patch from Slade Rich;
6156 added support for multiple code pages and multiple RAM banks on the
6157 PIC 14 port. The ASM files now no longer simply assume all the
6158 code / RAM are in the same page / bank. This means the linker can
6159 safely allocate code/RAM of separate ASM files to different pages/banks.
6160 * doc/sdccman.lyx: added Slade's tips
6161 * src/mcs51/peeph.def: fixed bug #880768

6170 * sim/ucsim/gui.src/serio.src/main.cc: Fixed unconditional use of
6173 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
6174 strtof is not part of C89 and isn't included with Mac OS X.
6176 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6178 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

6200 * src/ds390/gen.c (aopOp3): fixed the assignment of different dptrs to
6203 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
6205 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
6206 loaded with the linker search paths (-L arguments) and the libraries
6207 to be linked with the current source (-l arguments). Changes
6208 currently will affect only the pic16 port.
6209 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6210 include path the port specific paths and port specific libraries,
6211 * gplink command now contains the $3 argument,
6212 * src/pic16/device.h,
6213 * src/pic16/device.c,: structure PIC_device is made public and
6214 renamed to PIC16_device, the same for variable Pics which is renamed
6215 to Pics16. Updated all references to them.

6229 Documenting changes from previous commits.
6230 * configure.in (version 1.56),
6231 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6232 when generating output files to configure the pic16 library,
6233 but now I've commented it out, since gputils aren't installed in the
6234 SF compile farm, so library won't compile
6236 * device/lib/Makefile.in (version 1.56): initially I've added in
6237 target 'all' the prerequestive 'model-pic16' so it compiled the
6238 pic16 library, but now I've commented it out for the same reasons
6240 * added targets 'model-pic16' and 'objects-pic16' to compile the
6242 * added target 'port-specific-objects-pic16' to handle the
6243 generated libraries and copy them into the build/ directory
6244 * added target 'clean-intermediate-pic16' to clean intermediate
6245 files into pic16 directory
6246 * in target 'installdirs' added line to create directory pic16 in
6247 the installation path
6249 * device/include/Makefile.in (version 1.11): in target 'install'
6250 added lines to copy all header files to installation path,
6251 * in target 'installdirs' added line create directory for pic16
6252 headers in the installation path

6267 * src/z80/main.c (_parseOptions): fixed the portmode= command line
6268 option so that it actually works. Made it specific to the z80, since
6269 the gbz80 doesn't have these kinds of I/O ports.
6271 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6273 * device/include/z180.h,

6295 Mainly changes to support compilation of the device libraries
6296 * src/pic16/device.c: stack is allocated via symbol and not
6297 via literal number. The symbol is placed in the corresponding
6298 position of the data ram
6299 * (pic16_dump_section): relocatable and absolute uninitialized
6300 data are now emitted in sorted order to reduce section naming,
6301 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
6302 weren't marked as being in the access bank,
6304 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
6306 Added portion of GNU PIC Library under the directory
6307 device/include/pic16 and device/lib/pic16. These files
6308 contain the declarations of SFRs for the PIC18Fxx2 devices.
6309 The directory is initialized via configure from toplevel.
6311 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
6313 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

6325 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
6327 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
6328 in simpler and even better code

6338 * doc/sdccman.lyx: Moved and added some sections, small changes
6339 all over. Telling LaTeX to be less strict with word spacing
6340 to better keep the right margin. Changed some notes about
6341 maintainance of the ports in section 3.2.1 - is it OK like this?
6343 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

6381 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
6383 * src/pic16/peeph.def: all peepholes with movff are commented out,
6384 because there is a problem in the pcode peep optimizer,
6385 * src/pic16/ralloc.c: the register allocator can now reuse local

6537 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6539 PIC16 port related changes:
6540 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6541 added variable stackPos,
6543 * gen.c: genCall, assignResultValue: added support for
6544 pushing/retrieving function parameters to/from stack,
6545 genFunction,genEndFunction: setup stack frame for the
6547 genAddrOf: will be changed according to bug 863624
6549 * added files genutils.c and genutils.h which contain gen*
6550 debugged and optimised functions extracted from gen.c
6552 * glue.c: added variable 'externs' which holds extern symbols,
6553 pic16emitRegularMap: is modified to properly handle relocatable
6554 symbols under the new scheme,
6555 pic16createInterruptVect: is modified
6556 pic16printPublics: is modified to emit 'global' assembler directives,
6557 added pic16_printExterns to print extern symbols,
6558 pic16glue: initializes stack/frame pointer in the beginning of
6559 the assembly output. Temporary hack, will be corrected later,
6560 because gplink yet does not support stack and SDCC does not
6561 yet support a type of crt0.o object to create the final binary.
6563 * Removed many lines that contain 8051 legacy code.
6564 * The code is finally placed under a 'code' directive.
6565 * Added port specific options.
6567 * _process_pragma: simplified since now we do not need *special*
6568 include file to define SFR registers. But a separate header
6569 will be needed. This will be developed later.
6570 * _pic16_parseOptions: added, parses port specific options:
6571 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6572 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6573 --preplace-udata-with=
6575 * _pic16_setDefaultOptions: modified to initialize section names,
6576 but hack is temporarly out of order since it needs improvement.
6577 * _pic16_genAssemblerPreamble: configuration words are emitted by
6578 their address instead of their name. This part is incomplete and
6579 supports only the 18Fxx2 devices. Other devices will emit an error
6580 during assembly since they do not contain the same set of config
6582 * _pic16_genIVT: is modified,
6584 * pcode.c: added definitions for some hardware registers that are needed
6586 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6587 All PCI entries are updated. Now LFSR is supported.
6588 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6589 * added pic16_newpCodeOpLit2 to support instructions with
6590 two literal arguments
6591 * pic16_pCode2str: corrected code that emits assembler instructions
6592 with two literal operands and those that have an access bit modifier
6593 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6594 this fixes a bug which caused some labels to be lost, when an
6595 assembler directive was added, i.e. banksel,
6596 * pic16_FixRegisterBanking: improved logic that causes the insertion
6598 * InlineFunction: functions that are called once, are not any more
6599 inlined. This can be a port option in the future,
6601 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6603 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6604 hold the corresponding uninitialized symbols,
6605 * pic16_allocProcessorRegister: registers have explicit marked the
6607 * pic16_allocInternalRegister: registers are explicit marked as
6609 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6610 processing list, so bit registers were lost,
6613 * ralloc.h: added field 'accessBank' and original symbol operand
6614 in register definition,
6615 * removed the field isMapped from register definition,
6617 ** Several functions have been removed from various sources:
6618 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6619 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6620 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6621 pic16_assignRelocatableRegisters
6623 ** others have been introduced:
6624 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6625 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6627 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6629 * support/scripts/inc2h.pl: changed definition of BIT_AT
6630 to emit 'sbit at' instead of 'bit at'. This was a request.
6632 PIC16 port related preliminary changes:
6633 * gen.c: prefixed function popRegFromString with
6634 pic16_ and all references to it corrected
6635 * pcode.c: all pic16_pc_* hardware registers prefixed
6636 with underscore (_),
6637 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6638 * ralloc.c: newReg(): when register is REG_SFR then
6639 set address to rIdx,
6640 pic16_allocProcessorRegister(): marks register wasUsed=0
6641 pic16_writeUsedRegs(): added a call to assign processor
6642 registers via pic16_assignFixedRegisters
6644 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6646 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6647 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6648 variables in unused register banks. Also the SSEG is placed
6649 wherever there is enough space for it, and IDATA can be anywhere
6650 in internal RAM. For now compile using -Wl-Y[stack_size].
6651 The mem file is different for this option as well, since it
6652 makes no sense of talking about DSEG lenght.
6654 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6656 * src/SDCClrange.c: fixed bug 869095 that caused segfault

6901 * src/SDCCast.c (decorateType): disabled a transformation I added in
6902 revision 1.188 (access to fields of a structure at an absolute address);
6903 it breaks with bitfields, extern declarations, and gcse analysis.
6904 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
6905 could be assigned through a pointer, so don't complain.

7662 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
7663 fetching of the pointer
7664 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
7665 copied from genNearPointerSet()
7666 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
7667 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
7668 If they pop r0/r1 they must be called in the opposite order than aopOp().
7669 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
7670 (resp. --stack-auto), prepared for --xstack

7681 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
7683 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7684 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7685 type for bits was changed. It resulted in bit variables becoming
7686 global, which is not permitted in PIC 14 assembly output.
7688 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7690 * doc/sdccman.lyx: various additions and updates. Rearranged sections

7703 A few small changes that speed up the peephole optimizer.
7707 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7709 Try to make the peephole optimizer smarter by maintaining
7710 an association between the assembly source code and the
7711 iCodes that originated them. Put this information to use
7712 with a new peephole rule condition "notVolatile" so that
7713 the rules can be aggressive yet still safe.
7718 * src/mcs51/peeph.def
7720 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7724 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7725 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7726 if the left or right operand symbols have the accuse flag set.
7728 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7730 Changed the type of the result of the ! (NOT) operator to char;
7731 previously it returned the same type as the source. This allows
7732 us to eliminate all the genFloatNot functions (all of its target
7733 implementations were very buggy) since !float can use the same
7736 * src/SDCCicode.c (ast2iCode): ! returns char

7745 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7746 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7747 during interrupts. Ensure WSAVE is located at a shared bank address.
7748 2. Fixed page selection in some places
7749 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7750 the registers name strings.
7751 4. Fixed "signed / unsigned compare" compiler warnings.
7752 5. The PIC port manages its own allocation of the general purpose
7753 registers, but makes no attempt to reuse them. As a result when
7754 compiling it soon runs out of general purpose registers. Some
7755 additional code was added to the files pcode.c and device.c to walk
7756 through the function call tree and rename the registers so that they
7766 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
7767 genPlus() & genMinus() when the result is the same as left or right

7773 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7775 Made bitfield a distinct type from bit so that bitfields
7776 convert as per ANSI C and bits retain their traditional
7777 boolean style behaviour. Implemented bitfield support in
7785 * src/ds390/gen.c: bit v bitfield split
7786 * src/z80/gen.c: New support for bitfields
7787 * support/regression/tests/bitfields.c: reenabled z80,
7790 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7792 Rules 246.x, 247.x relate to bitfields, the others speed up
7793 access to xdata mapped I/O devices.
7795 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7797 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7799 Cleaned up genPackBits and genUnpackBits and added two helper
7800 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7801 for literal assignments in genPackBits (thanks to Frieder for
7807 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7809 Fixed bug #748310 (pointer to function type mishandled when the
7810 function name is omitted). Also fixed a SIGSEGV when a function
7811 attribute (reentrant, etc) is used on a non-function or on a
7812 function but misplaced before the parameter list.
7814 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
7816 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

7839 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7841 Made the constant following the "interrupt" keyword optional. If
7842 omitted, the function will not automatically be given an entry
7843 in the interrupt vector table (similar to #pragma NOIV, but
7844 less syntacticly kludgy). The interrupt number is also now
7845 range checked. Also fixed a bug in the high order bit example
7852 * support/Util/SDCCerr.c
7853 * support/Util/SDCCerr.h
7856 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

7859 * src/SDCCicode.c (operandOperation): rewritten some ops
7860 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
7861 * src/SDCCsymt.c (computeType): literals are handled the same way as any
7863 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
7864 be re-activated by defining REDUCE_LITERALS)
7865 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
7866 unsigned, but are signed by default
7867 * src/SDCCval.c (constVal): rearranged
7868 * src/SDCCval.c (valMod): preliminary fix
7869 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8321 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
8322 the regression tests I'm not brave enough to enable 245.b, 245.c
8323 * doc/sdccman.lyx: added latex preamble for hyperref package.
8324 Using pdflatex this will give you a hyperlinked pdf file with
8325 bookmarks. (prepend '%' before /usepackage if this breaks something)

8363 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
8365 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
8366 it can be defined with CFLAGS when running configure
8367 * src/SDCCmain.c: fixed compiling + linking with object files
8369 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

8372 added --disable-pic16-port
8373 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
8374 * src/SDCCmain.c: linkOptions is changed to set *,
8375 added if/endif conditional macros to remove options help
8376 messages from optionsTable when a port is not configured, added
8377 support for the PIc16 port in the ports table, when executing
8378 the compiler with no port specified on command line, a default
8379 port is selected with the new macro DEFAULT_PORT which is
8380 defined in port.h, in setDefaultOptions() linkOptions is removed
8381 from initialization assignment, since now it is a set,
8382 parseCmdLine uses setParseWithComma for linkOptions, in
8383 linkEdit() linkOptions are accessed with new function indexSet()
8384 which returns the i'th item of a set variable. See SDCCset.c, in
8385 linkEdit() when calling buildCmdLine(), added linkOptions as
8386 last argument. Now users can pass arguments to gplink via the
8387 -Wl option, main() uses pic16glue() to glue up pic16 programs

8399 * src/pic16/glue.c: commented out some error producing lines
8400 * src/pic16/main.c: __config directives are commented out to stop
8401 gpasm complaining and test the linkage with gplink, _linkCmd and
8402 _asmCmd changed to be more gplink and gpasm friendly
8403 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8404 produced an error when parsed, peep rule 12 is added to utilize
8405 movff, but it is commented out since the pCode does not support
8406 yet a command with 2 address arguments
8408 2003-05-18 <johan AT balder>
8410 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

8435 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
8437 2003-05-11 Borut Razem <borut.razem AT siol.net>
8439 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
8440 the path of bin directory, so that PATH is the only env. variable, which has to be set
8441 in case of standard installation.
8442 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

9524 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9525 not bytes. Function summary() which creates a memory usage summary
9526 file with extension .mem. Reports of overlaping stack and small stack
9527 size. If the space for the stack is less than 16 bytes aslink trows a
9530 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9531 the 8051. Option 'y' for memory summary output file.
9533 Changes to sdcc (All the changes are marked with 'JCF'):
9535 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9537 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9538 overlaying area for it (uses RegBankUsed[4]).
9540 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9541 bank zero as used by default. By default aslink locates the stack
9542 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9543 the creation of the .mem file. Delegates the allocation of data area
9544 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9545 the begining of the stack area to aslink.
9547 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9548 glue() in SDCCglue.c creates an area for it.
9550 2002-09-03 Borut Razem <borut.razem AT siol.net>
9551 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9552 sdcc/src/pic/glue.c:
9553 introduced atexit() handler for teporay files removal in case of
9554 errors, assertions, ...
9556 2002-08-29 Borut Razem <borut.razem AT siol.net>
9557 * sdcc/support/cpp2/auto-host_vc_in.h:
9558 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9559 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9560 Maybe there is a similar problem with BORLANDC? It should be checked!
9562 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9563 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9564 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9565 was not executed, and the compiler (cl) launched a warning:
9566 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9568 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9569 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9571 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9572 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9574 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9575 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9576 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9577 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9578 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9579 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9580 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9581 - added Release configuration in VS projects
9582 - review of compiler an linker options
9583 - VC .exe files are generated in bin_vc directory, not to interfere
9584 with binaries generated from other projects (cygwin, mingw, bcc ...)
9586 * sdcc/src/yacc.dsp: added
9588 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9589 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9590 and insert the version number definitions from .version
9592 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9594 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9595 added - genarate auto-host.h using auto-host_vc_in.h as template
9598 removed from CVS, generated automatically
9600 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9601 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9603 2002-08-11 Borut Razem <borut.razem AT siol.net>
9604 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9606 2002-08-10 Borut Razem <borut.razem AT siol.net>
9607 * src/SDCCmain.c (main):
9608 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9609 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9610 The consequence was that some temporary files were not removed.
9613 unification of code in functions tempfilename() and tempfile():
9614 function tempnam() is defined in Visual Studio 6.0 and .NET
9616 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9618 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9619 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9620 - removed compiler command line option /WX: Treats all warnings as errors
9621 - update a list of source files, included into the project
9623 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9624 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9625 changed project type to Generic Project so that can be correcly converted to VS.NET project
9627 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9629 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9631 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9633 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9634 added return 0 statements after assert() to make compiler happy
9636 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9637 added newline in the def file to keep MSC compiler satisfied
9639 * sdcc/src/z80/gen.c:
9640 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9641 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9642 - solved MSC error in function aopDump()
9644 * sdcc_vc.h: define PREFIX as "\\sdcc"
9646 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9647 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

9695 Added -p option. Allows port dependent processor to be specified.
9698 Initialized the new field char *Processor field to NULL in all ports
9701 Compiler generated registers for interrupt context saving
9702 were not getting allocated.
9704 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9707 Fixed left shift. Will promote the left side of a left shift
9708 if a) left shifting more than size of operand or b) when assigned
9709 to something size > size of left side
9711 2002-03-14 Scott Dattalo <scott AT dattalo.com>

9819 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
9821 * sdcc/src/SDCCloop.c:
9822 Previous fix was not good. basic blocks that have "break" or "return" are
9823 not really partof a loop , but live ranges used in these blocks should
9824 be live thru the entire loop, so set partOfLoop but don't add them to
9827 2002-02-21 <johan AT FRIJA>
9829 * src/SDCCcse.c: fixed bug #514308
9831 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>

9837 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
9839 2002-02-10 Karl Bongers <karl AT turbobit.com>
