3166 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
3168 Enabled VPATH feature: changed nearly all Makefiles (149 files).
3169 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
3171 One basic decision: e.g. src/clean.mk includes further files. In order
3172 to make this work there are two solutions:
3173 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
3174 run configure on them. This way they can use
3175 'include $(srcdir)/port-clean.mk'
3176 - always include clean.mk by the Makefile at the same level. To avoid
3177 that `make clean` tries to include and build Makefile.dep the
3178 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
3179 implemented, because now even `make uninstall` doesn't create
3180 Makefile.in. clean.mk could be eliminated by pasting it in
3183 * debugger/mcs51/Makefile.in: build own objects from library sources
3184 (SLIB, SDCC) in current directory
3186 * configure, configure.in: renamed --disable-device-lib-build in
3187 --disable-device-lib; added --enable-doc, the required tools are
3188 searched by configure; added result message; the toolchain for the
3189 belonging ports are now only built, if the port is enabled.
3191 * support/regression/*: all output is written in directory gen, because
3192 the fwk and ports directories don't livet in the build tree using vpath
3194 * doc/sdccman.lyx: renamed --disable-device-lib-build to
3195 --disable-device-lib, added --enable-doc, added section VPATH
3197 * sim/ucsim/configure.in,
3198 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
3199 z80 are enabled by default
3201 2006-04-24 Raphael Neider <rneider AT web.de>
3203 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
3204 to config word, "pic14_"-prefixed some extern functions
3205 (pic14_emitConfigWord): emit __config directive(s) if assignment to
3206 config word has been found
3207 * src/pic/device.h: added prototypes
3208 * src/pic/pcode.c: added "pic14_"-prefix where needed

3469 2006-03-24 Maarten Brock <sourceforge.brock AT dse.nl>
3471 * src/z80/gen.c (genFunction, genEndFunction): fixed bug 1160666,
3472 implemented patch 1120823 Thanks to Willy De la Court (normal
3473 interrupts need an interrupt number now if they are made critical),
3474 and enabled nesting of critical functions though not for gbz80
3475 (genCritical, genEndCritical): added functions
3476 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
3477 * src/z80/mappings.i: added "ei" to all mappings
3479 2006-03-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3481 * sim/ucsim/cmd.src/newcmdcl.h: applied patch fixing GCC 4.1 build
3482 submitted by the Debian SDCC maintainer Aurelien Jarno:
3483 "Credits goes to Martin Michlmayr, who rebuilt the whole Debian
3484 archive with gcc 4.1 on mips and wrote the patch"
3486 2006-03-16 Raphael Neider <rneider AT web.de>
3488 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
3489 the left operand is shorter than the result (c* = lit-c* + int),
3491 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
3494 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3496 * src/.version: increased version number to 2.5.5
3497 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
3498 linking is done manually in pic16 port's _linkEdit,
3499 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
3500 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
3501 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
3502 allocate asmop as AOP_ACC,
3503 (aopForRemat): added parameter 'bool result' in function declaration,
3504 (pic16_aopGet): return AOP_ACC when accessing WREG,
3505 (pic16_popGetTempReg): minor modification,
3506 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
3507 'pic16_allocWithIdx',
3508 (genPcall): removed ftype, usage of OP_SYM_TYPE asserted error when
3509 calling function in absolute addresses,
3510 (genAssign): take into account AOP_ACC asmop,
3511 * src/pic16/pcode.c (pic16_newpCodeOpReg): minor modifications,
3512 * src/pic16/pcoderegs.c: some debug functions and lines added,
3513 * src/pic16/ralloc.c (decodeRegType): added but commented out,
3514 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
3516 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
3517 call to allocReg, not by manually allocating a new one,
3518 (pic16_assignRegisters): now before going through the register
3519 allocating functions mark all registers as free. This eliminates some
3520 side effects resulting from peephole parser done earlier in the backbone
3522 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
3524 * src/SDCCicode.c (geniCodeLogic),

3542 * src/mcs51/gen.h: changed asmop.freed:1 to asmop.allocated for tracking
3543 * src/mcs51/gen.c (newAsmop): set asmop.allocated to 1,
3544 (aopForSym, aopOp): increment asmop.allocated if reused,
3545 (freeAsmop): decrement asmop.allocated and check for zero instead of
3547 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
3548 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,
3549 genCmpLt, genAndOp, genOrOp, genAnd, genOr, genXor, genRRC, genRLC,

3572 2006-03-06 Borut Razem <borut.razem AT siol.net>
3574 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
3575 made the linker quiet
3577 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
3579 * src/pic16/gen.c (genPcall): fixed bug #1443644
3580 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
3581 which dumps before the function entry point a data byte which represents
3582 the number of the local variables used by the specified function, added
3583 'xinst' for initial support for Extended Instruction Support,
3584 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
3585 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
3586 port->fun_prefix anymore (may change later),
3587 (genFunction, genEndFunction): do not store/restore local registers for
3588 _main (this should take care the --main-return command line option in
3590 (genOr): removed some legacy pic-port instructions,
3591 * src/pic16/genarith.c (genAddLit): re-enabled old code because
3592 performing operations with SFR's causes data to be written more than
3593 once to each SFR. Perhaps SFRs should be handled in special cases...
3594 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
3596 * src/pic16/main.c (_process_pragma): stack bound checking did not take
3597 into account for stack starting position,
3598 (struct OPTIONS pic16_optionsTable): added command line argument
3599 --extended or -y for Extended Instruction Support,
3600 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
3601 (deassignLRs): *** perhaps the most important change, old 'for' code
3602 (commented out for reference), didn't account for some registers which
3603 were left marked 'not free' after a pointer operation. The change
3604 reduces register usage a lot in some cases

5995 * (pic16_popGetTempRegCond): changed function prototype, now
5996 function takes also a bitVector argument v which holds the current
5997 set of registers that are allocated for stack access by aopForSym,
5998 registers allocated in aopForSym for accessing stack symbols are not
5999 any more part of the functions usedRegs field,
6000 * (genCall): some times aopOp is called for a stack variable to be
6001 send, aopForSym might perform the push, if this is true make sure
6002 that genCall doesn't push the variable twice by testing _G.resDirect,
6003 * (genFunction): changed testing for unspecified interrupt number
6004 from 256 to INTNO_UNSPEC,
6005 * modified selection scheme of frame pointer generation. Previously
6006 if function did use local registers a frame pointer was generated,
6007 now a frame pointer is generated only if function has arguments
6008 (that need PLUSW2 register access), or has stack arguments, or the
6009 compiler is not instructed to omit the frame pointer,
6010 * (genEndFunction): before restoring local registers that were saved
6011 in the function preamble, also restore the registers that *might*
6012 have been allocated for stack access,
6013 * (genRet): removed some old comments,
6014 * (genCmp, the active (RN's) version): added a call to the
6015 pic16_genCmp_special function to perform the compare with a more
6016 robust and optimized way,
6017 * (genInline): a feature has been added in inline code generation,
6018 which allows a wildcard variable substitution when writing inline
6019 assembly. Code is incomplete and experimental therefore undocumented,
6020 * (genCast): changed order of aopOp for result and right to allow
6021 aopForSym to directly load the result if possible,
6022 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
6023 perform an optimized compare on some selected special occasions,
6024 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
6025 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
6026 generate an IVT any more,
6027 * src/pic16/main.c (pic16_optionsTable): added command line option
6029 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
6030 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
6032 * src/pic16/NOTES: Raphael Neider added in list of active developers
6033 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
6034 jumptable_end to prevent bug #,
6035 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
6036 inCond and outCond fields,
6037 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
6038 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
6039 turn off register spilling,
6040 * (packRegsForOneUse): synced with other ports' versions although it
6041 is not used currently,
6042 * (pic16_packRegisters): added an optimization while reading
6043 structure bitfields, some registers may be saved (malloc code is
6044 decreased by 80 bytes)
6046 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
6048 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
6049 left is a bitfield, if yes, then don't optimize assignment. Perhaps
6050 this can be optimized more?
6052 2005-03-10 Raphael Neider <rneider AT web.de>
6054 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
6055 genNearPointerGet): (hopefully) fixed access to bitfields via
6056 pointers (p->bitN = x; and x = p->bitN; failed)
6058 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

6382 access stack and frame pointers. They are initially assigned to
6383 point at pic16_pc_fsr1[lh] and pic16_pc_fsr2[lh] variables and other
6384 accessing SFRs. Updated all occurences of modification of stack or
6385 frame pointer in gen.c and pcode.c,
6386 * src/pic16/ralloc.c (serialRegAssign): fixed two bugs with
6387 assigning of a literal value to pointers,

6430 from Raphael Neider,
6431 * src/pic16/pcode.c (pic16_newpCodeOpLit): removed casting to char
6432 for 8-bit literals. This fixes some literal operands which are sign
6433 extended to 16-bits ints when instruction needs only 8-bits.

6690 Adding support for replacing ljmps with sjmps in jumptables
6691 generated for switch statements. For now you need to set the
6692 environment variable SDCC_SJMP_JUMPTABLE to enable this.
6693 Now 4 algorithms for mcs51 jumptable generation are used:
6694 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
6695 addresses loaded pc-relative for up to 112 cases and stack-pushing
6696 target addresses loaded with offset from dptr for up to 256 cases.

6728 * added libc directory. The current version of LibC contains string
6729 functions, ctype functions and macros and some functions of the
6730 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
6731 be extensively tested in the future. Standard disclaimer here.

6745 * (genCmp): experimental code for new genCmp which uses PIC18's
6746 special compare&skip instructions. Initial tests fail some times
6747 with variables grater than 1 byte in size, so new code is disabled,
6748 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
6750 * (genCast): began a fix to optimize the casting of a bit to another
6751 bit, now assigning a bitfield to another bitfield will fail, sorry,

6766 * src/pic16/ralloc.c (allocReg): add preliminary support for
6767 supporting a limited set of temporary registers,

9774 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
9776 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
9777 loaded with the linker search paths (-L arguments) and the libraries
9778 to be linked with the current source (-l arguments). Changes
9779 currently will affect only the pic16 port.
9780 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
9781 include path the port specific paths and port specific libraries,
9782 * gplink command now contains the $3 argument,
9783 * src/pic16/device.h,
9784 * src/pic16/device.c,: structure PIC_device is made public and
9785 renamed to PIC16_device, the same for variable Pics which is renamed

9800 Documenting changes from previous commits.
9801 * configure.in (version 1.56),
9802 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
9803 when generating output files to configure the pic16 library,
9804 but now I've commented it out, since gputils aren't installed in the
9805 SF compile farm, so library won't compile
9807 * device/lib/Makefile.in (version 1.56): initially I've added in
9808 target 'all' the prerequestive 'model-pic16' so it compiled the
9809 pic16 library, but now I've commented it out for the same reasons
9811 * added targets 'model-pic16' and 'objects-pic16' to compile the
9813 * added target 'port-specific-objects-pic16' to handle the
9814 generated libraries and copy them into the build/ directory
9815 * added target 'clean-intermediate-pic16' to clean intermediate
9816 files into pic16 directory
9817 * in target 'installdirs' added line to create directory pic16 in

9821 added lines to copy all header files to installation path,
9822 * in target 'installdirs' added line create directory for pic16
9823 headers in the installation path

9838 * src/z80/main.c (_parseOptions): fixed the portmode= command line
9839 option so that it actually works. Made it specific to the z80, since
9840 the gbz80 doesn't have these kinds of I/O ports.
9842 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9844 * device/include/z180.h,

9868 via literal number. The symbol is placed in the corresponding
9869 position of the data ram
9870 * (pic16_dump_section): relocatable and absolute uninitialized
9871 data are now emitted in sorted order to reduce section naming,
9872 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
9873 weren't marked as being in the access bank,
9875 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
9877 Added portion of GNU PIC Library under the directory

10069 (default behaviour).
10071 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10073 A python script to validate compiler diagnostic messages. It can be
10074 used to verify that sdcc complains about bad c source code and
10075 gives a good location of the error.
10076 * support/valdiag/Makefile,
10077 * support/valdiag/valdiag.py,
10078 * support/valdiag/tests/*
10080 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

10108 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
10110 PIC16 port related changes:
10111 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
10112 added variable stackPos,
10114 * gen.c: genCall, assignResultValue: added support for
10115 pushing/retrieving function parameters to/from stack,
10116 genFunction,genEndFunction: setup stack frame for the
10117 generated function,
10118 genAddrOf: will be changed according to bug 863624
10120 * added files genutils.c and genutils.h which contain gen*
10121 debugged and optimised functions extracted from gen.c
10123 * glue.c: added variable 'externs' which holds extern symbols,
10124 pic16emitRegularMap: is modified to properly handle relocatable
10125 symbols under the new scheme,
10126 pic16createInterruptVect: is modified
10127 pic16printPublics: is modified to emit 'global' assembler directives,
10128 added pic16_printExterns to print extern symbols,
10129 pic16glue: initializes stack/frame pointer in the beginning of
10130 the assembly output. Temporary hack, will be corrected later,
10131 because gplink yet does not support stack and SDCC does not
10132 yet support a type of crt0.o object to create the final binary.
10134 * Removed many lines that contain 8051 legacy code.
10135 * The code is finally placed under a 'code' directive.
10136 * Added port specific options.
10138 * _process_pragma: simplified since now we do not need *special*
10139 include file to define SFR registers. But a separate header
10140 will be needed. This will be developed later.
10141 * _pic16_parseOptions: added, parses port specific options:
10142 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
10143 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
10144 --preplace-udata-with=
10146 * _pic16_setDefaultOptions: modified to initialize section names,
10147 but hack is temporarly out of order since it needs improvement.
10148 * _pic16_genAssemblerPreamble: configuration words are emitted by
10149 their address instead of their name. This part is incomplete and
10150 supports only the 18Fxx2 devices. Other devices will emit an error
10151 during assembly since they do not contain the same set of config
10153 * _pic16_genIVT: is modified,
10155 * pcode.c: added definitions for some hardware registers that are needed
10157 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
10158 All PCI entries are updated. Now LFSR is supported.
10159 * Removed pic16_pciTRIS is mentioned by mdubuc in source
10160 * added pic16_newpCodeOpLit2 to support instructions with
10161 two literal arguments
10162 * pic16_pCode2str: corrected code that emits assembler instructions
10163 with two literal operands and those that have an access bit modifier
10164 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
10165 this fixes a bug which caused some labels to be lost, when an
10166 assembler directive was added, i.e. banksel,
10167 * pic16_FixRegisterBanking: improved logic that causes the insertion
10169 * InlineFunction: functions that are called once, are not any more
10170 inlined. This can be a port option in the future,
10172 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
10174 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
10175 hold the corresponding uninitialized symbols,
10176 * pic16_allocProcessorRegister: registers have explicit marked the
10178 * pic16_allocInternalRegister: registers are explicit marked as
10180 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
10181 processing list, so bit registers were lost,
10184 * ralloc.h: added field 'accessBank' and original symbol operand
10185 in register definition,
10186 * removed the field isMapped from register definition,
10188 ** Several functions have been removed from various sources:
10189 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
10190 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
10191 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
10192 pic16_assignRelocatableRegisters
10194 ** others have been introduced:
10195 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
10196 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
10198 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
10200 * support/scripts/inc2h.pl: changed definition of BIT_AT
10201 to emit 'sbit at' instead of 'bit at'. This was a request.
10203 PIC16 port related preliminary changes:
10204 * gen.c: prefixed function popRegFromString with
10205 pic16_ and all references to it corrected
10206 * pcode.c: all pic16_pc_* hardware registers prefixed
10207 with underscore (_),
10208 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
10209 * ralloc.c: newReg(): when register is REG_SFR then
10210 set address to rIdx,
10211 pic16_allocProcessorRegister(): marks register wasUsed=0
10212 pic16_writeUsedRegs(): added a call to assign processor
10213 registers via pic16_assignFixedRegisters
10215 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10217 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
10218 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
10219 variables in unused register banks. Also the SSEG is placed
10220 wherever there is enough space for it, and IDATA can be anywhere
10221 in internal RAM. For now compile using -Wl-Y[stack_size].
10222 The mem file is different for this option as well, since it
10223 makes no sense of talking about DSEG lenght.
10225 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
10227 * src/SDCClrange.c: fixed bug 869095 that caused segfault
10228 in certain cases, e.g. when ROM assignment, patch provided
10229 from Albert den Haan.

11114 * src/SDCCsymt.c (sclsFromPtr),
11116 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
11117 support for standard C idiom of memory mapped variables; for
11118 example, *((xdata int*)0x1234) = 1 is now internally equivalent
11119 to xdata int at 0x1234 tempvar = 1.
11120 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
11121 provided by Akiya ISHIDA

11137 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11139 Fixed bug #621531 (const & volatile confusion in the type chain).
11140 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
11141 refer to the const or volatile state of the pointer itself.

11211 2003-09-04 Bernhard Held <bernhard AT bernhardheld.de>
11213 * device/lib/_mullong.c: replaced int by short for gcc
11215 2003-08-31 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11217 * src/SDCCpeeph.c (notVolatile, notVolatileVariable): handle IFX
11218 and JUMPTABLE iCodes properly now (worked by accident before)
11219 * src/mcs51/gen.c (leftRightUseAcc),
11220 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
11221 iCode properly now. Use getSize instead of nRegs since a & b
11222 aren't part of the nRegs tally.
11224 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
11226 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

11232 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
11233 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
11234 fetching of the pointer
11235 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
11236 copied from genNearPointerSet()
11237 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
11238 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
11239 If they pop r0/r1 they must be called in the opposite order than aopOp().
11240 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
11241 (resp. --stack-auto), prepared for --xstack
11243 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
11245 * doc/sdccman.lyx: reverted tables to those in cvs 1.64
11247 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>

11250 these ports have their own __sdcc_external_start()
11252 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
11254 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
11255 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
11256 type for bits was changed. It resulted in bit variables becoming
11257 global, which is not permitted in PIC 14 assembly output.
11259 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
11261 * doc/sdccman.lyx: various additions and updates. Rearranged sections
11263 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11265 Z80 and MCS51 linkers complaint if a public symbol is defined

11272 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11274 A few small changes that speed up the peephole optimizer.
11278 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11280 Try to make the peephole optimizer smarter by maintaining
11281 an association between the assembly source code and the
11282 iCodes that originated them. Put this information to use
11283 with a new peephole rule condition "notVolatile" so that
11284 the rules can be aggressive yet still safe.
11289 * src/mcs51/peeph.def
11291 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11295 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
11296 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
11297 if the left or right operand symbols have the accuse flag set.
11299 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11301 Changed the type of the result of the ! (NOT) operator to char;
11302 previously it returned the same type as the source. This allows
11303 us to eliminate all the genFloatNot functions (all of its target
11304 implementations were very buggy) since !float can use the same
11307 * src/SDCCicode.c (ast2iCode): ! returns char

11316 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
11317 1. Interrupt would not compile properly. Ensure PCLATH register is saved
11318 during interrupts. Ensure WSAVE is located at a shared bank address.
11319 2. Fixed page selection in some places
11320 3. Fixed BTFSS/C to where necessary use registers directly and not simply
11321 the registers name strings.
11322 4. Fixed "signed / unsigned compare" compiler warnings.
11323 5. The PIC port manages its own allocation of the general purpose
11324 registers, but makes no attempt to reuse them. As a result when
11325 compiling it soon runs out of general purpose registers. Some
11326 additional code was added to the files pcode.c and device.c to walk
11327 through the function call tree and rename the registers so that they
11337 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
11338 genPlus() & genMinus() when the result is the same as left or right
11340 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

11344 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11346 Made bitfield a distinct type from bit so that bitfields
11347 convert as per ANSI C and bits retain their traditional
11348 boolean style behaviour. Implemented bitfield support in
11356 * src/ds390/gen.c: bit v bitfield split
11357 * src/z80/gen.c: New support for bitfields
11358 * support/regression/tests/bitfields.c: reenabled z80,
11361 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
11363 Rules 246.x, 247.x relate to bitfields, the others speed up
11364 access to xdata mapped I/O devices.
11366 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
11368 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11370 Cleaned up genPackBits and genUnpackBits and added two helper
11371 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
11372 for literal assignments in genPackBits (thanks to Frieder for
11378 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11380 Fixed bug #748310 (pointer to function type mishandled when the
11381 function name is omitted). Also fixed a SIGSEGV when a function
11382 attribute (reentrant, etc) is used on a non-function or on a
11383 function but misplaced before the parameter list.
11385 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
11387 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
11388 * support/Util/SDCCerr.h,
11389 * support/Util/SDCCerr.c: Added func attr misuse error msg
11391 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
11393 Fixed bug #787649 by anonymous
11394 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
11395 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
11397 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11399 Fixed numerous bitfield problems.
11401 * src/SDCC.y: More bitfield related error checking

11410 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11412 Made the constant following the "interrupt" keyword optional. If
11413 omitted, the function will not automatically be given an entry
11414 in the interrupt vector table (similar to #pragma NOIV, but
11415 less syntacticly kludgy). The interrupt number is also now
11416 range checked. Also fixed a bug in the high order bit example
11423 * support/Util/SDCCerr.c
11424 * support/Util/SDCCerr.h
11427 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
11429 * src/SDCCcse.c (algebraicOpts): fix bug converting op from value to type
11430 * src/SDCCicode.c (operandOperation): rewritten some ops

11949 the compiler with no port specified on command line, a default
11950 port is selected with the new macro DEFAULT_PORT which is
11951 defined in port.h, in setDefaultOptions() linkOptions is removed

13040 * src/mcs51/main.c: removed {bindir}{sep} from aslink
13042 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13044 * in /sdcc/as/mcs51/ changed these files in order to create an
13045 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
13046 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
13047 following files to include the previous two files: aslink.dsp,
13048 Makefile.aslink, Makefile.bcc, and Makefile.in.
13050 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
13051 .adb instead of .cdb
13053 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13055 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
13056 value from option --iram-size.
13058 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13060 * /sdcc/as/mcs51/lklist.c: added boundary check before using
13063 2002-09-18 <wiml AT hhhh.org>
13065 * SDCClrange.h: exposed setFromRange() and setToRange()
13066 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
13067 packRegsForAccUse() (bug 542397)
13068 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
13069 multiple times and emitting the fetch operations more than once
13070 added aopGetUsesAcc() function to allow binary operators to
13071 fetch their operands in the correct order; made genMinus() emit
13072 compact code for X = LITERAL - Y
13074 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13075 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
13076 sprintf() in line 1267.
13078 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13079 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
13082 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13083 Changes to aslink (All the changes are marked with 'JCF'):
13085 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
13088 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
13089 area BSEG. Also moves, if possible, the DATA area down into the internal
13090 ram so more space is available.
13092 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
13095 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
13096 not bytes. Function summary() which creates a memory usage summary
13097 file with extension .mem. Reports of overlaping stack and small stack
13098 size. If the space for the stack is less than 16 bytes aslink trows a
13101 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
13102 the 8051. Option 'y' for memory summary output file.
13104 Changes to sdcc (All the changes are marked with 'JCF'):
13106 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
13108 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
13109 overlaying area for it (uses RegBankUsed[4]).
13111 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
13112 bank zero as used by default. By default aslink locates the stack
13113 (equivalent to --stack-after-data). Pass option 'y' to aslink for
13114 the creation of the .mem file. Delegates the allocation of data area
13115 to aslink (it is not longer 0x30 by default). If --stack-loc passes
13116 the begining of the stack area to aslink.
13118 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
13119 glue() in SDCCglue.c creates an area for it.
13121 2002-09-03 Borut Razem <borut.razem AT siol.net>
13122 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
13123 sdcc/src/pic/glue.c:
13124 introduced atexit() handler for teporay files removal in case of
13125 errors, assertions, ...
13127 2002-08-29 Borut Razem <borut.razem AT siol.net>
13128 * sdcc/support/cpp2/auto-host_vc_in.h:
13129 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
13130 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
13131 Maybe there is a similar problem with BORLANDC? It should be checked!
13133 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
13134 corrected improper use of assert: the assignment to clr variable was done inside the assert.
13135 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
13136 was not executed, and the compiler (cl) launched a warning:
13137 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
13139 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
13140 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
13142 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
13143 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
13145 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,

13150 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
13151 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
13152 - added Release configuration in VS projects
13153 - review of compiler an linker options
13154 - VC .exe files are generated in bin_vc directory, not to interfere
13155 with binaries generated from other projects (cygwin, mingw, bcc ...)
13157 * sdcc/src/yacc.dsp: added
13159 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
13160 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
13161 and insert the version number definitions from .version

13165 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
13166 added - genarate auto-host.h using auto-host_vc_in.h as template
13169 removed from CVS, generated automatically
13171 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
13172 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
13174 2002-08-11 Borut Razem <borut.razem AT siol.net>
13175 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
13177 2002-08-10 Borut Razem <borut.razem AT siol.net>
13178 * src/SDCCmain.c (main):
13179 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
13180 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
13181 The consequence was that some temporary files were not removed.
13184 unification of code in functions tempfilename() and tempfile():
13185 function tempnam() is defined in Visual Studio 6.0 and .NET
13187 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
13189 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
13190 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
13191 - removed compiler command line option /WX: Treats all warnings as errors
13192 - update a list of source files, included into the project
13194 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
13195 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
13196 changed project type to Generic Project so that can be correcly converted to VS.NET project
13198 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
13200 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
13202 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
13204 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:

13211 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
13212 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
13213 - solved MSC error in function aopDump()

13393 Previous fix was not good. basic blocks that have "break" or "return" are
13394 not really partof a loop , but live ranges used in these blocks should
