3159 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
3161 Enabled VPATH feature: changed nearly all Makefiles (149 files).
3162 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
3164 One basic decision: e.g. src/clean.mk includes further files. In order
3165 to make this work there are two solutions:
3166 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
3167 run configure on them. This way they can use
3168 'include $(srcdir)/port-clean.mk'
3169 - always include clean.mk by the Makefile at the same level. To avoid
3170 that `make clean` tries to include and build Makefile.dep the
3171 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
3172 implemented, because now even `make uninstall` doesn't create
3173 Makefile.in. clean.mk could be eliminated by pasting it in
3176 * debugger/mcs51/Makefile.in: build own objects from library sources
3177 (SLIB, SDCC) in current directory
3179 * configure, configure.in: renamed --disable-device-lib-build in
3180 --disable-device-lib; added --enable-doc, the required tools are
3181 searched by configure; added result message; the toolchain for the
3182 belonging ports are now only built, if the port is enabled.
3184 * support/regression/*: all output is written in directory gen, because
3185 the fwk and ports directories don't livet in the build tree using vpath
3187 * doc/sdccman.lyx: renamed --disable-device-lib-build to
3188 --disable-device-lib, added --enable-doc, added section VPATH
3190 * sim/ucsim/configure.in,
3191 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
3192 z80 are enabled by default
3194 2006-04-24 Raphael Neider <rneider AT web.de>
3196 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
3197 to config word, "pic14_"-prefixed some extern functions
3198 (pic14_emitConfigWord): emit __config directive(s) if assignment to
3199 config word has been found
3200 * src/pic/device.h: added prototypes
3201 * src/pic/pcode.c: added "pic14_"-prefix where needed
3202 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
3204 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

3218 fixes #1469504 and #1474602,
3219 (pCodeRegOptimizeRegUsage): fixed typo in comment

3223 * device/examples/main8051.c: deleted - it was removed from CVS

3469 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
3470 * src/z80/mappings.i: added "ei" to all mappings
3472 2006-03-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3474 * sim/ucsim/cmd.src/newcmdcl.h: applied patch fixing GCC 4.1 build
3475 submitted by the Debian SDCC maintainer Aurelien Jarno:
3476 "Credits goes to Martin Michlmayr, who rebuilt the whole Debian
3477 archive with gcc 4.1 on mips and wrote the patch"
3479 2006-03-16 Raphael Neider <rneider AT web.de>
3481 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
3482 the left operand is shorter than the result (c* = lit-c* + int),
3484 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
3487 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3489 * src/.version: increased version number to 2.5.5
3490 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
3491 linking is done manually in pic16 port's _linkEdit,
3492 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
3493 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
3494 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
3495 allocate asmop as AOP_ACC,
3496 (aopForRemat): added parameter 'bool result' in function declaration,
3497 (pic16_aopGet): return AOP_ACC when accessing WREG,
3498 (pic16_popGetTempReg): minor modification,
3499 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
3500 'pic16_allocWithIdx',
3501 (genPcall): removed ftype, usage of OP_SYM_TYPE asserted error when
3502 calling function in absolute addresses,
3503 (genAssign): take into account AOP_ACC asmop,
3504 * src/pic16/pcode.c (pic16_newpCodeOpReg): minor modifications,
3505 * src/pic16/pcoderegs.c: some debug functions and lines added,
3506 * src/pic16/ralloc.c (decodeRegType): added but commented out,
3507 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
3509 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
3510 call to allocReg, not by manually allocating a new one,
3511 (pic16_assignRegisters): now before going through the register
3512 allocating functions mark all registers as free. This eliminates some
3513 side effects resulting from peephole parser done earlier in the backbone
3515 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

3535 * src/mcs51/gen.h: changed asmop.freed:1 to asmop.allocated for tracking
3536 * src/mcs51/gen.c (newAsmop): set asmop.allocated to 1,
3537 (aopForSym, aopOp): increment asmop.allocated if reused,
3538 (freeAsmop): decrement asmop.allocated and check for zero instead of
3540 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
3541 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,

3568 made the linker quiet
3570 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
3572 * src/pic16/gen.c (genPcall): fixed bug #1443644
3573 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
3574 which dumps before the function entry point a data byte which represents
3575 the number of the local variables used by the specified function, added
3576 'xinst' for initial support for Extended Instruction Support,
3577 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
3578 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
3579 port->fun_prefix anymore (may change later),
3580 (genFunction, genEndFunction): do not store/restore local registers for
3581 _main (this should take care the --main-return command line option in
3583 (genOr): removed some legacy pic-port instructions,
3584 * src/pic16/genarith.c (genAddLit): re-enabled old code because
3585 performing operations with SFR's causes data to be written more than
3586 once to each SFR. Perhaps SFRs should be handled in special cases...
3587 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
3589 * src/pic16/main.c (_process_pragma): stack bound checking did not take
3590 into account for stack starting position,

3592 --extended or -y for Extended Instruction Support,
3593 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
3594 (deassignLRs): *** perhaps the most important change, old 'for' code
3595 (commented out for reference), didn't account for some registers which
3596 were left marked 'not free' after a pointer operation. The change
3597 reduces register usage a lot in some cases

5955 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
5957 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
5959 * device/lib/printf_large.c: removed inline assembly for portability and
5960 readability. Use printf_fast if speed or size are more important.
5961 * src/pic16/gen.c: removed conditions around use of DEBUGpc
5962 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
5964 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
5966 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
5967 prevent compiler warning
5969 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
5971 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
5972 moved to level 0 and declared as static. Also they are explicit
5973 placed in access bank. This was necessery because some times they
5974 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
5975 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
5976 optimizations. Currently only compare to unsigned char is implemented,
5977 * src/pic16/gen.c: added fReturnIdx array,
5978 * (struct resolvedIfx) is moved to gen.h and made public,
5979 * (struct _G): added sregsAlloc and sregsAllocSet fields,
5980 * (aopForSym): added an optimization to directly store in stack of
5981 the operand of a SEND iCode,
5982 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
5983 but as registers instead (AOP_REG) using the fReturnIdx array,
5984 * (pic16_freeAsmop): remove the freed register from the
5985 _G.sregsAlloc field,
5986 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
5987 a compare of 'WREG',
5988 * (pic16_popGetTempRegCond): changed function prototype, now
5989 function takes also a bitVector argument v which holds the current
5990 set of registers that are allocated for stack access by aopForSym,
5991 registers allocated in aopForSym for accessing stack symbols are not
5992 any more part of the functions usedRegs field,
5993 * (genCall): some times aopOp is called for a stack variable to be
5994 send, aopForSym might perform the push, if this is true make sure
5995 that genCall doesn't push the variable twice by testing _G.resDirect,
5996 * (genFunction): changed testing for unspecified interrupt number
5997 from 256 to INTNO_UNSPEC,
5998 * modified selection scheme of frame pointer generation. Previously
5999 if function did use local registers a frame pointer was generated,
6000 now a frame pointer is generated only if function has arguments
6001 (that need PLUSW2 register access), or has stack arguments, or the
6002 compiler is not instructed to omit the frame pointer,
6003 * (genEndFunction): before restoring local registers that were saved
6004 in the function preamble, also restore the registers that *might*
6005 have been allocated for stack access,
6006 * (genRet): removed some old comments,
6007 * (genCmp, the active (RN's) version): added a call to the
6008 pic16_genCmp_special function to perform the compare with a more
6009 robust and optimized way,
6010 * (genInline): a feature has been added in inline code generation,
6011 which allows a wildcard variable substitution when writing inline
6012 assembly. Code is incomplete and experimental therefore undocumented,
6013 * (genCast): changed order of aopOp for result and right to allow
6014 aopForSym to directly load the result if possible,
6015 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
6016 perform an optimized compare on some selected special occasions,

6034 is not used currently,
6035 * (pic16_packRegisters): added an optimization while reading
6036 structure bitfields, some registers may be saved (malloc code is
6037 decreased by 80 bytes)

6683 Adding support for replacing ljmps with sjmps in jumptables
6684 generated for switch statements. For now you need to set the
6685 environment variable SDCC_SJMP_JUMPTABLE to enable this.
6686 Now 4 algorithms for mcs51 jumptable generation are used:
6687 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
6688 addresses loaded pc-relative for up to 112 cases and stack-pushing
6689 target addresses loaded with offset from dptr for up to 256 cases.

6721 * added libc directory. The current version of LibC contains string
6722 functions, ctype functions and macros and some functions of the
6723 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
6724 be extensively tested in the future. Standard disclaimer here.

6737 * (pic16_storeForReturn): optimized return of 0,
6738 * (genCmp): experimental code for new genCmp which uses PIC18's
6739 special compare&skip instructions. Initial tests fail some times
6740 with variables grater than 1 byte in size, so new code is disabled,
6741 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
6743 * (genCast): began a fix to optimize the casting of a bit to another
6744 bit, now assigning a bitfield to another bitfield will fail, sorry,

6758 registers when it shouldn't,
6759 * src/pic16/ralloc.c (allocReg): add preliminary support for
6760 supporting a limited set of temporary registers,
6762 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9769 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
9770 loaded with the linker search paths (-L arguments) and the libraries
9771 to be linked with the current source (-l arguments). Changes
9772 currently will affect only the pic16 port.
9773 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
9774 include path the port specific paths and port specific libraries,
9775 * gplink command now contains the $3 argument,
9776 * src/pic16/device.h,
9777 * src/pic16/device.c,: structure PIC_device is made public and
9778 renamed to PIC16_device, the same for variable Pics which is renamed

9793 Documenting changes from previous commits.
9794 * configure.in (version 1.56),
9795 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
9796 when generating output files to configure the pic16 library,
9797 but now I've commented it out, since gputils aren't installed in the
9798 SF compile farm, so library won't compile
9800 * device/lib/Makefile.in (version 1.56): initially I've added in
9801 target 'all' the prerequestive 'model-pic16' so it compiled the
9802 pic16 library, but now I've commented it out for the same reasons
9804 * added targets 'model-pic16' and 'objects-pic16' to compile the
9806 * added target 'port-specific-objects-pic16' to handle the
9807 generated libraries and copy them into the build/ directory
9808 * added target 'clean-intermediate-pic16' to clean intermediate
9809 files into pic16 directory
9810 * in target 'installdirs' added line to create directory pic16 in

9832 option so that it actually works. Made it specific to the z80, since
9833 the gbz80 doesn't have these kinds of I/O ports.
9835 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

10013 * (pic14emitOverlay): modified to emit a commented overlay segment
10014 directive when no overlay data exist
10015 * (picglue): modified to emit uninitialized data segment
10016 according to udata_section_name
10017 * src/pic/main.c (_pic14_parseOptions): added command line

10059 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10061 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
10062 (default behaviour).
10064 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10066 A python script to validate compiler diagnostic messages. It can be
10067 used to verify that sdcc complains about bad c source code and
10068 gives a good location of the error.
10069 * support/valdiag/Makefile,
10070 * support/valdiag/valdiag.py,
10071 * support/valdiag/tests/*
10073 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10075 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),

10098 * src/ds390/gen.c (genRightShift): fixed bug #870788
10099 * src/SDCCast.c (decorateType): fixed bug #870781
10101 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
10103 PIC16 port related changes:
10104 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
10105 added variable stackPos,
10107 * gen.c: genCall, assignResultValue: added support for
10108 pushing/retrieving function parameters to/from stack,
10109 genFunction,genEndFunction: setup stack frame for the
10110 generated function,
10111 genAddrOf: will be changed according to bug 863624
10113 * added files genutils.c and genutils.h which contain gen*
10114 debugged and optimised functions extracted from gen.c
10116 * glue.c: added variable 'externs' which holds extern symbols,
10117 pic16emitRegularMap: is modified to properly handle relocatable
10118 symbols under the new scheme,
10119 pic16createInterruptVect: is modified
10120 pic16printPublics: is modified to emit 'global' assembler directives,
10121 added pic16_printExterns to print extern symbols,
10122 pic16glue: initializes stack/frame pointer in the beginning of
10123 the assembly output. Temporary hack, will be corrected later,
10124 because gplink yet does not support stack and SDCC does not
10125 yet support a type of crt0.o object to create the final binary.
10127 * Removed many lines that contain 8051 legacy code.
10128 * The code is finally placed under a 'code' directive.
10129 * Added port specific options.
10131 * _process_pragma: simplified since now we do not need *special*
10132 include file to define SFR registers. But a separate header
10133 will be needed. This will be developed later.
10134 * _pic16_parseOptions: added, parses port specific options:
10135 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
10136 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
10137 --preplace-udata-with=
10139 * _pic16_setDefaultOptions: modified to initialize section names,
10140 but hack is temporarly out of order since it needs improvement.
10141 * _pic16_genAssemblerPreamble: configuration words are emitted by
10142 their address instead of their name. This part is incomplete and
10143 supports only the 18Fxx2 devices. Other devices will emit an error
10144 during assembly since they do not contain the same set of config
10146 * _pic16_genIVT: is modified,
10148 * pcode.c: added definitions for some hardware registers that are needed
10150 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
10151 All PCI entries are updated. Now LFSR is supported.
10152 * Removed pic16_pciTRIS is mentioned by mdubuc in source
10153 * added pic16_newpCodeOpLit2 to support instructions with
10154 two literal arguments
10155 * pic16_pCode2str: corrected code that emits assembler instructions
10156 with two literal operands and those that have an access bit modifier
10157 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
10158 this fixes a bug which caused some labels to be lost, when an
10159 assembler directive was added, i.e. banksel,
10160 * pic16_FixRegisterBanking: improved logic that causes the insertion
10162 * InlineFunction: functions that are called once, are not any more
10163 inlined. This can be a port option in the future,
10165 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
10167 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
10168 hold the corresponding uninitialized symbols,
10169 * pic16_allocProcessorRegister: registers have explicit marked the
10171 * pic16_allocInternalRegister: registers are explicit marked as
10173 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
10174 processing list, so bit registers were lost,
10177 * ralloc.h: added field 'accessBank' and original symbol operand
10178 in register definition,
10179 * removed the field isMapped from register definition,
10181 ** Several functions have been removed from various sources:
10182 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
10183 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
10184 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
10185 pic16_assignRelocatableRegisters
10187 ** others have been introduced:
10188 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
10189 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
10191 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
10193 * support/scripts/inc2h.pl: changed definition of BIT_AT
10194 to emit 'sbit at' instead of 'bit at'. This was a request.
10196 PIC16 port related preliminary changes:
10197 * gen.c: prefixed function popRegFromString with
10198 pic16_ and all references to it corrected
10199 * pcode.c: all pic16_pc_* hardware registers prefixed
10200 with underscore (_),
10201 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
10202 * ralloc.c: newReg(): when register is REG_SFR then
10203 set address to rIdx,
10204 pic16_allocProcessorRegister(): marks register wasUsed=0
10205 pic16_writeUsedRegs(): added a call to assign processor
10206 registers via pic16_assignFixedRegisters
10208 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10210 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
10211 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
10212 variables in unused register banks. Also the SSEG is placed
10213 wherever there is enough space for it, and IDATA can be anywhere
10214 in internal RAM. For now compile using -Wl-Y[stack_size].
10215 The mem file is different for this option as well, since it
10216 makes no sense of talking about DSEG lenght.
10218 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
10220 * src/SDCClrange.c: fixed bug 869095 that caused segfault
10221 in certain cases, e.g. when ROM assignment, patch provided
10222 from Albert den Haan.

10943 my_unput() replaced by unput()
10945 2003-10-05 Bernhard Held <bernhard AT bernhardheld.de>
10947 * src/SDCCloop.c (assignmentsToSym, loopInduction): cast argument of
10948 setToNull() to (void *) to avoid gcc3.x's warning: "dereferencing
10949 type-punned pointer will break strict-aliasing rules"

11052 genCodePointerGet, genGenPointerGet, genFarPointerSet,
11053 genGenPointerSet): handle AOP_DPTR correctly when loading dptr
11054 (ralloc doesn't intentionally do this now, but perhaps later)
11055 * src/mcs51/ralloc.c (serialRegAssign, fillGaps),
11056 * src/ds390/ralloc.c (serialRegAssign, fillGaps): fixed some

11090 * src/ds390/gen.c (genFunction, genEndFunction): Moved save
11091 and restore of EA so that stack offsets to parameters are
11092 correct when using both critical and reentrant/stack-auto.

11107 * src/SDCCsymt.c (sclsFromPtr),
11109 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
11110 support for standard C idiom of memory mapped variables; for
11111 example, *((xdata int*)0x1234) = 1 is now internally equivalent
11112 to xdata int at 0x1234 tempvar = 1.
11113 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
11114 provided by Akiya ISHIDA

11130 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11132 Fixed bug #621531 (const & volatile confusion in the type chain).
11133 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
11134 refer to the const or volatile state of the pointer itself.

11199 pcodeflow.c, pcodeflow.h, pcode.h, pcodepeep.c, pcoderegs.c,
11200 pcoderegs.h, ralloc.c, ralloc.h
11201 * main.c: added top header and GPL license notice

11204 2003-09-04 Bernhard Held <bernhard AT bernhardheld.de>
11206 * device/lib/_mullong.c: replaced int by short for gcc
11208 2003-08-31 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11210 * src/SDCCpeeph.c (notVolatile, notVolatileVariable): handle IFX
11211 and JUMPTABLE iCodes properly now (worked by accident before)
11212 * src/mcs51/gen.c (leftRightUseAcc),
11213 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
11214 iCode properly now. Use getSize instead of nRegs since a & b
11215 aren't part of the nRegs tally.
11217 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
11219 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

11229 copied from genNearPointerSet()
11230 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
11231 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
11232 If they pop r0/r1 they must be called in the opposite order than aopOp().
11233 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
11234 (resp. --stack-auto), prepared for --xstack
11236 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
11238 * doc/sdccman.lyx: reverted tables to those in cvs 1.64
11240 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>

11243 these ports have their own __sdcc_external_start()
11245 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
11247 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
11248 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
11249 type for bits was changed. It resulted in bit variables becoming
11250 global, which is not permitted in PIC 14 assembly output.
11252 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
11254 * doc/sdccman.lyx: various additions and updates. Rearranged sections
11256 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11258 Z80 and MCS51 linkers complaint if a public symbol is defined

11265 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11267 A few small changes that speed up the peephole optimizer.
11271 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11273 Try to make the peephole optimizer smarter by maintaining
11274 an association between the assembly source code and the
11275 iCodes that originated them. Put this information to use
11276 with a new peephole rule condition "notVolatile" so that
11277 the rules can be aggressive yet still safe.
11282 * src/mcs51/peeph.def
11284 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11288 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
11289 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
11290 if the left or right operand symbols have the accuse flag set.
11292 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11294 Changed the type of the result of the ! (NOT) operator to char;
11295 previously it returned the same type as the source. This allows
11296 us to eliminate all the genFloatNot functions (all of its target
11297 implementations were very buggy) since !float can use the same
11300 * src/SDCCicode.c (ast2iCode): ! returns char

11309 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
11310 1. Interrupt would not compile properly. Ensure PCLATH register is saved
11311 during interrupts. Ensure WSAVE is located at a shared bank address.
11312 2. Fixed page selection in some places
11313 3. Fixed BTFSS/C to where necessary use registers directly and not simply
11314 the registers name strings.
11315 4. Fixed "signed / unsigned compare" compiler warnings.
11316 5. The PIC port manages its own allocation of the general purpose
11317 registers, but makes no attempt to reuse them. As a result when
11318 compiling it soon runs out of general purpose registers. Some
11319 additional code was added to the files pcode.c and device.c to walk
11320 through the function call tree and rename the registers so that they
11330 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
11331 genPlus() & genMinus() when the result is the same as left or right
11333 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11335 * src/z80/gen.c (isUnsplitable, fetchPairLong): fixed bug #770454
11337 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11339 Made bitfield a distinct type from bit so that bitfields
11340 convert as per ANSI C and bits retain their traditional
11341 boolean style behaviour. Implemented bitfield support in
11349 * src/ds390/gen.c: bit v bitfield split
11350 * src/z80/gen.c: New support for bitfields
11351 * support/regression/tests/bitfields.c: reenabled z80,
11354 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
11356 Rules 246.x, 247.x relate to bitfields, the others speed up
11357 access to xdata mapped I/O devices.
11359 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
11361 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11363 Cleaned up genPackBits and genUnpackBits and added two helper
11364 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
11365 for literal assignments in genPackBits (thanks to Frieder for
11371 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11373 Fixed bug #748310 (pointer to function type mishandled when the
11374 function name is omitted). Also fixed a SIGSEGV when a function
11375 attribute (reentrant, etc) is used on a non-function or on a
11376 function but misplaced before the parameter list.
11378 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
11380 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
11381 * support/Util/SDCCerr.h,
11382 * support/Util/SDCCerr.c: Added func attr misuse error msg
11384 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
11386 Fixed bug #787649 by anonymous
11387 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
11388 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
11390 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11392 Fixed numerous bitfield problems.
11394 * src/SDCC.y: More bitfield related error checking
11396 * src/SDCCsymt.c (compStructSize): fixed bitfield offset calc
11397 * support/Util/SDCCerr.h,
11398 * support/Util/SDCCerr.c: Added & edited some bitfield err msgs
11399 * src/mcs51/gen.c (genPackBits, genUnpackBits): fixed mask bugs
11400 * src/ds390/gen.c (genPackBits, genUnpackBits): fixed mask bugs
11401 * support/regression/tests/bitfields.c: tests added
11403 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11405 Made the constant following the "interrupt" keyword optional. If
11406 omitted, the function will not automatically be given an entry
11407 in the interrupt vector table (similar to #pragma NOIV, but
11408 less syntacticly kludgy). The interrupt number is also now
11409 range checked. Also fixed a bug in the high order bit example
11416 * support/Util/SDCCerr.c
11417 * support/Util/SDCCerr.h
11420 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
11422 * src/SDCCcse.c (algebraicOpts): fix bug converting op from value to type
11423 * src/SDCCicode.c (operandOperation): rewritten some ops
11424 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
11425 * src/SDCCsymt.c (computeType): literals are handled the same way as any
11427 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
11428 be re-activated by defining REDUCE_LITERALS)
11429 * src/SDCCval.c (constVal): fixed; hex and octal constants can be

11939 added if/endif conditional macros to remove options help
11940 messages from optionsTable when a port is not configured, added
11941 support for the PIc16 port in the ports table, when executing
11942 the compiler with no port specified on command line, a default
11943 port is selected with the new macro DEFAULT_PORT which is
11944 defined in port.h, in setDefaultOptions() linkOptions is removed
11945 from initialization assignment, since now it is a set,
11946 parseCmdLine uses setParseWithComma for linkOptions, in
11947 linkEdit() linkOptions are accessed with new function indexSet()
11948 which returns the i'th item of a set variable. See SDCCset.c, in
11949 linkEdit() when calling buildCmdLine(), added linkOptions as
11950 last argument. Now users can pass arguments to gplink via the
11951 -Wl option, main() uses pic16glue() to glue up pic16 programs

13022 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
13023 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

13029 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
13030 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
13032 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
13033 * src/mcs51/main.c: removed {bindir}{sep} from aslink
13035 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13037 * in /sdcc/as/mcs51/ changed these files in order to create an
13038 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
13039 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
13040 following files to include the previous two files: aslink.dsp,
13041 Makefile.aslink, Makefile.bcc, and Makefile.in.
13043 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
13044 .adb instead of .cdb
13046 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13048 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
13049 value from option --iram-size.
13051 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13053 * /sdcc/as/mcs51/lklist.c: added boundary check before using
13056 2002-09-18 <wiml AT hhhh.org>
13058 * SDCClrange.h: exposed setFromRange() and setToRange()
13059 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
13060 packRegsForAccUse() (bug 542397)
13061 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
13062 multiple times and emitting the fetch operations more than once
13063 added aopGetUsesAcc() function to allow binary operators to
13064 fetch their operands in the correct order; made genMinus() emit
13065 compact code for X = LITERAL - Y
13067 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13068 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
13069 sprintf() in line 1267.
13071 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13072 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
13075 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13076 Changes to aslink (All the changes are marked with 'JCF'):
13078 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
13081 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
13082 area BSEG. Also moves, if possible, the DATA area down into the internal
13083 ram so more space is available.
13085 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
13088 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
13089 not bytes. Function summary() which creates a memory usage summary
13090 file with extension .mem. Reports of overlaping stack and small stack
13091 size. If the space for the stack is less than 16 bytes aslink trows a
13094 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
13095 the 8051. Option 'y' for memory summary output file.
13097 Changes to sdcc (All the changes are marked with 'JCF'):
13099 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
13101 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
13102 overlaying area for it (uses RegBankUsed[4]).
13104 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
13105 bank zero as used by default. By default aslink locates the stack
13106 (equivalent to --stack-after-data). Pass option 'y' to aslink for
13107 the creation of the .mem file. Delegates the allocation of data area
13108 to aslink (it is not longer 0x30 by default). If --stack-loc passes
13109 the begining of the stack area to aslink.
13111 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
13112 glue() in SDCCglue.c creates an area for it.
13114 2002-09-03 Borut Razem <borut.razem AT siol.net>
13115 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
13116 sdcc/src/pic/glue.c:
13117 introduced atexit() handler for teporay files removal in case of
13118 errors, assertions, ...
13120 2002-08-29 Borut Razem <borut.razem AT siol.net>
13121 * sdcc/support/cpp2/auto-host_vc_in.h:
13122 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
13123 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
13124 Maybe there is a similar problem with BORLANDC? It should be checked!
13126 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
13127 corrected improper use of assert: the assignment to clr variable was done inside the assert.
13128 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
13129 was not executed, and the compiler (cl) launched a warning:
13130 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
13132 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
13133 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
13135 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
13136 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
13138 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
13139 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
13140 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
13141 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
13142 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
13143 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
13144 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
13145 - added Release configuration in VS projects
13146 - review of compiler an linker options
13147 - VC .exe files are generated in bin_vc directory, not to interfere
13148 with binaries generated from other projects (cygwin, mingw, bcc ...)
13150 * sdcc/src/yacc.dsp: added
13152 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
13153 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
13154 and insert the version number definitions from .version
13156 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
13158 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
13159 added - genarate auto-host.h using auto-host_vc_in.h as template
13162 removed from CVS, generated automatically
13164 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
13165 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
13167 2002-08-11 Borut Razem <borut.razem AT siol.net>
13168 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
13170 2002-08-10 Borut Razem <borut.razem AT siol.net>
13171 * src/SDCCmain.c (main):
13172 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
13173 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
13174 The consequence was that some temporary files were not removed.
13177 unification of code in functions tempfilename() and tempfile():
13178 function tempnam() is defined in Visual Studio 6.0 and .NET
13180 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
13182 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
13183 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
13184 - removed compiler command line option /WX: Treats all warnings as errors
13185 - update a list of source files, included into the project
13187 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
13188 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
13189 changed project type to Generic Project so that can be correcly converted to VS.NET project
13191 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
13193 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
13195 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
13197 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
13198 added return 0 statements after assert() to make compiler happy
13200 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
13201 added newline in the def file to keep MSC compiler satisfied
13203 * sdcc/src/z80/gen.c:
13204 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
13205 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
13206 - solved MSC error in function aopDump()
