2288 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
2290 Enabled VPATH feature: changed nearly all Makefiles (149 files).
2291 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
2293 One basic decision: e.g. src/clean.mk includes further files. In order
2294 to make this work there are two solutions:
2295 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
2296 run configure on them. This way they can use
2297 'include $(srcdir)/port-clean.mk'
2298 - always include clean.mk by the Makefile at the same level. To avoid
2299 that `make clean` tries to include and build Makefile.dep the
2300 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
2301 implemented, because now even `make uninstall` doesn't create
2302 Makefile.in. clean.mk could be eliminated by pasting it in
2305 * debugger/mcs51/Makefile.in: build own objects from library sources
2306 (SLIB, SDCC) in current directory
2308 * configure, configure.in: renamed --disable-device-lib-build in
2309 --disable-device-lib; added --enable-doc, the required tools are
2310 searched by configure; added result message; the toolchain for the
2311 belonging ports are now only built, if the port is enabled.
2313 * support/regression/*: all output is written in directory gen, because
2314 the fwk and ports directories don't livet in the build tree using vpath
2316 * doc/sdccman.lyx: renamed --disable-device-lib-build to
2317 --disable-device-lib, added --enable-doc, added section VPATH
2319 * sim/ucsim/configure.in,
2320 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
2321 z80 are enabled by default
2323 2006-04-24 Raphael Neider <rneider AT web.de>
2325 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
2326 to config word, "pic14_"-prefixed some extern functions
2327 (pic14_emitConfigWord): emit __config directive(s) if assignment to
2328 config word has been found
2329 * src/pic/device.h: added prototypes
2330 * src/pic/pcode.c: added "pic14_"-prefix where needed
2331 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
2333 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

2348 (pCodeRegOptimizeRegUsage): fixed typo in comment

2608 2006-03-16 Raphael Neider <rneider AT web.de>
2610 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
2611 the left operand is shorter than the result (c* = lit-c* + int),
2613 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
2616 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2618 * src/.version: increased version number to 2.5.5
2619 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
2620 linking is done manually in pic16 port's _linkEdit,
2621 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
2622 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
2623 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
2624 allocate asmop as AOP_ACC,
2625 (aopForRemat): added parameter 'bool result' in function declaration,
2626 (pic16_aopGet): return AOP_ACC when accessing WREG,
2627 (pic16_popGetTempReg): minor modification,
2628 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
2629 'pic16_allocWithIdx',
2630 (genPcall): removed ftype, usage of OP_SYM_TYPE asserted error when
2631 calling function in absolute addresses,
2632 (genAssign): take into account AOP_ACC asmop,
2633 * src/pic16/pcode.c (pic16_newpCodeOpReg): minor modifications,
2634 * src/pic16/pcoderegs.c: some debug functions and lines added,
2635 * src/pic16/ralloc.c (decodeRegType): added but commented out,
2636 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
2638 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
2639 call to allocReg, not by manually allocating a new one,
2640 (pic16_assignRegisters): now before going through the register
2641 allocating functions mark all registers as free. This eliminates some
2642 side effects resulting from peephole parser done earlier in the backbone
2644 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
2646 * src/SDCCicode.c (geniCodeLogic),

2664 * src/mcs51/gen.h: changed asmop.freed:1 to asmop.allocated for tracking
2665 * src/mcs51/gen.c (newAsmop): set asmop.allocated to 1,
2666 (aopForSym, aopOp): increment asmop.allocated if reused,
2667 (freeAsmop): decrement asmop.allocated and check for zero instead of
2669 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
2670 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,
2671 genCmpLt, genAndOp, genOrOp, genAnd, genOr, genXor, genRRC, genRLC,

2692 * support/regression/tests/array.c: added parenthesis, made arrays unsigned
2694 2006-03-06 Borut Razem <borut.razem AT siol.net>
2696 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
2697 made the linker quiet
2699 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
2701 * src/pic16/gen.c (genPcall): fixed bug #1443644
2702 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
2703 which dumps before the function entry point a data byte which represents
2704 the number of the local variables used by the specified function, added
2705 'xinst' for initial support for Extended Instruction Support,
2706 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
2707 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
2708 port->fun_prefix anymore (may change later),
2709 (genFunction, genEndFunction): do not store/restore local registers for
2710 _main (this should take care the --main-return command line option in
2712 (genOr): removed some legacy pic-port instructions,
2713 * src/pic16/genarith.c (genAddLit): re-enabled old code because
2714 performing operations with SFR's causes data to be written more than
2715 once to each SFR. Perhaps SFRs should be handled in special cases...
2716 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
2718 * src/pic16/main.c (_process_pragma): stack bound checking did not take
2719 into account for stack starting position,
2720 (struct OPTIONS pic16_optionsTable): added command line argument
2721 --extended or -y for Extended Instruction Support,
2722 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
2723 (deassignLRs): *** perhaps the most important change, old 'for' code
2724 (commented out for reference), didn't account for some registers which
2725 were left marked 'not free' after a pointer operation. The change
2726 reduces register usage a lot in some cases

5084 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
5086 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
5088 * device/lib/printf_large.c: removed inline assembly for portability and
5089 readability. Use printf_fast if speed or size are more important.
5090 * src/pic16/gen.c: removed conditions around use of DEBUGpc
5091 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
5093 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
5095 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
5096 prevent compiler warning
5098 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
5100 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
5101 moved to level 0 and declared as static. Also they are explicit
5102 placed in access bank. This was necessery because some times they
5103 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
5104 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
5105 optimizations. Currently only compare to unsigned char is implemented,
5106 * src/pic16/gen.c: added fReturnIdx array,
5107 * (struct resolvedIfx) is moved to gen.h and made public,
5108 * (struct _G): added sregsAlloc and sregsAllocSet fields,
5109 * (aopForSym): added an optimization to directly store in stack of
5110 the operand of a SEND iCode,
5111 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
5112 but as registers instead (AOP_REG) using the fReturnIdx array,
5113 * (pic16_freeAsmop): remove the freed register from the
5114 _G.sregsAlloc field,
5115 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
5116 a compare of 'WREG',
5117 * (pic16_popGetTempRegCond): changed function prototype, now
5118 function takes also a bitVector argument v which holds the current
5119 set of registers that are allocated for stack access by aopForSym,
5120 registers allocated in aopForSym for accessing stack symbols are not
5121 any more part of the functions usedRegs field,
5122 * (genCall): some times aopOp is called for a stack variable to be
5123 send, aopForSym might perform the push, if this is true make sure
5124 that genCall doesn't push the variable twice by testing _G.resDirect,
5125 * (genFunction): changed testing for unspecified interrupt number
5126 from 256 to INTNO_UNSPEC,
5127 * modified selection scheme of frame pointer generation. Previously
5128 if function did use local registers a frame pointer was generated,
5129 now a frame pointer is generated only if function has arguments
5130 (that need PLUSW2 register access), or has stack arguments, or the
5131 compiler is not instructed to omit the frame pointer,
5132 * (genEndFunction): before restoring local registers that were saved
5133 in the function preamble, also restore the registers that *might*
5134 have been allocated for stack access,
5135 * (genRet): removed some old comments,
5136 * (genCmp, the active (RN's) version): added a call to the
5137 pic16_genCmp_special function to perform the compare with a more
5138 robust and optimized way,
5139 * (genInline): a feature has been added in inline code generation,
5140 which allows a wildcard variable substitution when writing inline
5141 assembly. Code is incomplete and experimental therefore undocumented,
5142 * (genCast): changed order of aopOp for result and right to allow
5143 aopForSym to directly load the result if possible,
5144 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,

5812 Adding support for replacing ljmps with sjmps in jumptables
5813 generated for switch statements. For now you need to set the
5814 environment variable SDCC_SJMP_JUMPTABLE to enable this.
5815 Now 4 algorithms for mcs51 jumptable generation are used:
5816 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
5817 addresses loaded pc-relative for up to 112 cases and stack-pushing
5818 target addresses loaded with offset from dptr for up to 256 cases.

5848 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
5850 * added libc directory. The current version of LibC contains string
5851 functions, ctype functions and macros and some functions of the
5852 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
5853 be extensively tested in the future. Standard disclaimer here.
5854 Library is not automatically build yet. But one can build it by
5855 invoking 'make' inside the libc directory.

5866 * (pic16_storeForReturn): optimized return of 0,
5867 * (genCmp): experimental code for new genCmp which uses PIC18's
5868 special compare&skip instructions. Initial tests fail some times
5869 with variables grater than 1 byte in size, so new code is disabled,
5870 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5872 * (genCast): began a fix to optimize the casting of a bit to another
5873 bit, now assigning a bitfield to another bitfield will fail, sorry,

5882 and 1 for banking instruction,
5883 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
5884 caused stop processing pCodes after a inline assembly block,
5885 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

5887 registers when it shouldn't,
5888 * src/pic16/ralloc.c (allocReg): add preliminary support for
5889 supporting a limited set of temporary registers,
5891 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8899 loaded with the linker search paths (-L arguments) and the libraries
8900 to be linked with the current source (-l arguments). Changes
8901 currently will affect only the pic16 port.
8902 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8903 include path the port specific paths and port specific libraries,
8904 * gplink command now contains the $3 argument,
8905 * src/pic16/device.h,
8906 * src/pic16/device.c,: structure PIC_device is made public and

8922 Documenting changes from previous commits.
8923 * configure.in (version 1.56),
8924 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8925 when generating output files to configure the pic16 library,
8926 but now I've commented it out, since gputils aren't installed in the
8927 SF compile farm, so library won't compile
8929 * device/lib/Makefile.in (version 1.56): initially I've added in
8930 target 'all' the prerequestive 'model-pic16' so it compiled the
8931 pic16 library, but now I've commented it out for the same reasons
8933 * added targets 'model-pic16' and 'objects-pic16' to compile the
8935 * added target 'port-specific-objects-pic16' to handle the
8936 generated libraries and copy them into the build/ directory
8937 * added target 'clean-intermediate-pic16' to clean intermediate
8938 files into pic16 directory
8939 * in target 'installdirs' added line to create directory pic16 in

9184 * src/SDCCast.c (decorateType),
9185 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
9186 LEFT_OP (left shift)
9188 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9190 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
9191 (default behaviour).
9193 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9195 A python script to validate compiler diagnostic messages. It can be
9196 used to verify that sdcc complains about bad c source code and
9197 gives a good location of the error.
9198 * support/valdiag/Makefile,
9199 * support/valdiag/valdiag.py,
9200 * support/valdiag/tests/*
9202 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9217 Bug reported from Jesus Calvino-Fraga
9219 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
9221 * sdcc.spec: updated
9222 * device/include/Makefile.in: don't install CVS directories
9223 * device/lib/Makefile.in: added removal of CVS directories after install
9224 * doc/Makefile: fixed install, added local_icons
9225 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
9226 * src/mcs51/gen.c (genRightShift): fixed bug #870788
9227 * src/ds390/gen.c (genRightShift): fixed bug #870788
9228 * src/SDCCast.c (decorateType): fixed bug #870781
9230 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
9232 PIC16 port related changes:
9233 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
9234 added variable stackPos,
9236 * gen.c: genCall, assignResultValue: added support for
9237 pushing/retrieving function parameters to/from stack,
9238 genFunction,genEndFunction: setup stack frame for the
9240 genAddrOf: will be changed according to bug 863624
9242 * added files genutils.c and genutils.h which contain gen*
9243 debugged and optimised functions extracted from gen.c
9245 * glue.c: added variable 'externs' which holds extern symbols,
9246 pic16emitRegularMap: is modified to properly handle relocatable
9247 symbols under the new scheme,
9248 pic16createInterruptVect: is modified
9249 pic16printPublics: is modified to emit 'global' assembler directives,
9250 added pic16_printExterns to print extern symbols,
9251 pic16glue: initializes stack/frame pointer in the beginning of
9252 the assembly output. Temporary hack, will be corrected later,
9253 because gplink yet does not support stack and SDCC does not
9254 yet support a type of crt0.o object to create the final binary.
9256 * Removed many lines that contain 8051 legacy code.
9257 * The code is finally placed under a 'code' directive.
9258 * Added port specific options.
9260 * _process_pragma: simplified since now we do not need *special*
9261 include file to define SFR registers. But a separate header
9262 will be needed. This will be developed later.
9263 * _pic16_parseOptions: added, parses port specific options:
9264 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
9265 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
9266 --preplace-udata-with=
9268 * _pic16_setDefaultOptions: modified to initialize section names,
9269 but hack is temporarly out of order since it needs improvement.
9270 * _pic16_genAssemblerPreamble: configuration words are emitted by
9271 their address instead of their name. This part is incomplete and
9272 supports only the 18Fxx2 devices. Other devices will emit an error
9273 during assembly since they do not contain the same set of config
9275 * _pic16_genIVT: is modified,
9277 * pcode.c: added definitions for some hardware registers that are needed
9279 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
9280 All PCI entries are updated. Now LFSR is supported.
9281 * Removed pic16_pciTRIS is mentioned by mdubuc in source
9282 * added pic16_newpCodeOpLit2 to support instructions with
9283 two literal arguments
9284 * pic16_pCode2str: corrected code that emits assembler instructions
9285 with two literal operands and those that have an access bit modifier
9286 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
9287 this fixes a bug which caused some labels to be lost, when an
9288 assembler directive was added, i.e. banksel,
9289 * pic16_FixRegisterBanking: improved logic that causes the insertion
9291 * InlineFunction: functions that are called once, are not any more
9292 inlined. This can be a port option in the future,
9294 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
9296 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
9297 hold the corresponding uninitialized symbols,
9298 * pic16_allocProcessorRegister: registers have explicit marked the
9300 * pic16_allocInternalRegister: registers are explicit marked as
9302 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
9303 processing list, so bit registers were lost,
9306 * ralloc.h: added field 'accessBank' and original symbol operand
9307 in register definition,
9308 * removed the field isMapped from register definition,
9310 ** Several functions have been removed from various sources:
9311 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
9312 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
9313 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
9314 pic16_assignRelocatableRegisters
9316 ** others have been introduced:
9317 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
9318 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
9320 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
9322 * support/scripts/inc2h.pl: changed definition of BIT_AT
9323 to emit 'sbit at' instead of 'bit at'. This was a request.
9325 PIC16 port related preliminary changes:
9326 * gen.c: prefixed function popRegFromString with
9327 pic16_ and all references to it corrected
9328 * pcode.c: all pic16_pc_* hardware registers prefixed
9329 with underscore (_),
9330 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
9331 * ralloc.c: newReg(): when register is REG_SFR then
9332 set address to rIdx,
9333 pic16_allocProcessorRegister(): marks register wasUsed=0
9334 pic16_writeUsedRegs(): added a call to assign processor
9335 registers via pic16_assignFixedRegisters
9337 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9339 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
9340 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
9341 variables in unused register banks. Also the SSEG is placed
9342 wherever there is enough space for it, and IDATA can be anywhere
9343 in internal RAM. For now compile using -Wl-Y[stack_size].
9344 The mem file is different for this option as well, since it
9345 makes no sense of talking about DSEG lenght.
9347 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
9349 * src/SDCClrange.c: fixed bug 869095 that caused segfault
9350 in certain cases, e.g. when ROM assignment, patch provided
9351 from Albert den Haan.

9592 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9594 * src/SDCCast.c (decorateType): disabled a transformation I added in
9595 revision 1.188 (access to fields of a structure at an absolute address);
9596 it breaks with bitfields, extern declarations, and gcse analysis.
9597 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
9598 could be assigned through a pointer, so don't complain.
9599 * src/SDCCast.c (astErrors),
9601 * src/SDCCglue.c (emitRegularMap): fixed bug #847813
9603 2003-11-26 Vangelis Rokas <vrokas AT otenet.gr>

10340 and JUMPTABLE iCodes properly now (worked by accident before)
10341 * src/mcs51/gen.c (leftRightUseAcc),
10342 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
10343 iCode properly now. Use getSize instead of nRegs since a & b
10344 aren't part of the nRegs tally.
10346 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
10348 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

10358 copied from genNearPointerSet()
10359 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
10360 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
10361 If they pop r0/r1 they must be called in the opposite order than aopOp().
10362 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
10363 (resp. --stack-auto), prepared for --xstack
10365 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

10376 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10377 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
10378 type for bits was changed. It resulted in bit variables becoming
10379 global, which is not permitted in PIC 14 assembly output.
10381 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10383 * doc/sdccman.lyx: various additions and updates. Rearranged sections

10396 A few small changes that speed up the peephole optimizer.
10400 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10402 Try to make the peephole optimizer smarter by maintaining
10403 an association between the assembly source code and the
10404 iCodes that originated them. Put this information to use
10405 with a new peephole rule condition "notVolatile" so that
10406 the rules can be aggressive yet still safe.
10411 * src/mcs51/peeph.def
10413 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10417 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
10418 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
10419 if the left or right operand symbols have the accuse flag set.
10421 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10423 Changed the type of the result of the ! (NOT) operator to char;
10424 previously it returned the same type as the source. This allows
10425 us to eliminate all the genFloatNot functions (all of its target
10426 implementations were very buggy) since !float can use the same
10429 * src/SDCCicode.c (ast2iCode): ! returns char

10438 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10439 1. Interrupt would not compile properly. Ensure PCLATH register is saved
10440 during interrupts. Ensure WSAVE is located at a shared bank address.
10441 2. Fixed page selection in some places
10442 3. Fixed BTFSS/C to where necessary use registers directly and not simply
10443 the registers name strings.
10444 4. Fixed "signed / unsigned compare" compiler warnings.
10445 5. The PIC port manages its own allocation of the general purpose
10446 registers, but makes no attempt to reuse them. As a result when
10447 compiling it soon runs out of general purpose registers. Some
10448 additional code was added to the files pcode.c and device.c to walk
10449 through the function call tree and rename the registers so that they
10459 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
10460 genPlus() & genMinus() when the result is the same as left or right

10466 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10468 Made bitfield a distinct type from bit so that bitfields
10469 convert as per ANSI C and bits retain their traditional
10470 boolean style behaviour. Implemented bitfield support in
10478 * src/ds390/gen.c: bit v bitfield split
10479 * src/z80/gen.c: New support for bitfields
10480 * support/regression/tests/bitfields.c: reenabled z80,
10483 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10485 Rules 246.x, 247.x relate to bitfields, the others speed up
10486 access to xdata mapped I/O devices.
10488 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
10490 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10492 Cleaned up genPackBits and genUnpackBits and added two helper
10493 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
10494 for literal assignments in genPackBits (thanks to Frieder for
10500 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10502 Fixed bug #748310 (pointer to function type mishandled when the
10503 function name is omitted). Also fixed a SIGSEGV when a function
10504 attribute (reentrant, etc) is used on a non-function or on a
10505 function but misplaced before the parameter list.
10507 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
10509 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
10510 * support/Util/SDCCerr.h,

10532 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10534 Made the constant following the "interrupt" keyword optional. If
10535 omitted, the function will not automatically be given an entry
10536 in the interrupt vector table (similar to #pragma NOIV, but
10537 less syntacticly kludgy). The interrupt number is also now
10538 range checked. Also fixed a bug in the high order bit example

11068 added if/endif conditional macros to remove options help
11069 messages from optionsTable when a port is not configured, added
11070 support for the PIc16 port in the ports table, when executing
11071 the compiler with no port specified on command line, a default
11072 port is selected with the new macro DEFAULT_PORT which is
11073 defined in port.h, in setDefaultOptions() linkOptions is removed
11074 from initialization assignment, since now it is a set,
11075 parseCmdLine uses setParseWithComma for linkOptions, in
11076 linkEdit() linkOptions are accessed with new function indexSet()
11077 which returns the i'th item of a set variable. See SDCCset.c, in
11078 linkEdit() when calling buildCmdLine(), added linkOptions as
11079 last argument. Now users can pass arguments to gplink via the
11080 -Wl option, main() uses pic16glue() to glue up pic16 programs

11093 * src/pic16/main.c: __config directives are commented out to stop
11094 gpasm complaining and test the linkage with gplink, _linkCmd and
11095 _asmCmd changed to be more gplink and gpasm friendly
11096 * src/pic16/peeph.def: peep rule 3 is commented out, since it
11097 produced an error when parsed, peep rule 12 is added to utilize
11098 movff, but it is commented out since the pCode does not support
11099 yet a command with 2 address arguments
11101 2003-05-18 <johan AT balder>
11103 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

11122 Fixed so you can set breakpoints prior to run, run does not stop
11123 on entry now. Add tbreak. Other enhancements and fixes for use
11126 2003-05-12 Borut Razem <borut.razem AT siol.net>
11128 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
11130 2003-05-11 Borut Razem <borut.razem AT siol.net>
11132 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

12151 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
12152 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

12158 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
12159 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
12161 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
12162 * src/mcs51/main.c: removed {bindir}{sep} from aslink
12164 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12166 * in /sdcc/as/mcs51/ changed these files in order to create an
12167 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
12168 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
12169 following files to include the previous two files: aslink.dsp,
12170 Makefile.aslink, Makefile.bcc, and Makefile.in.
12172 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
12173 .adb instead of .cdb
12175 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12177 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
12178 value from option --iram-size.
12180 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12182 * /sdcc/as/mcs51/lklist.c: added boundary check before using
12185 2002-09-18 <wiml AT hhhh.org>
12187 * SDCClrange.h: exposed setFromRange() and setToRange()
12188 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
12189 packRegsForAccUse() (bug 542397)
12190 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
12191 multiple times and emitting the fetch operations more than once
12192 added aopGetUsesAcc() function to allow binary operators to
12193 fetch their operands in the correct order; made genMinus() emit
12194 compact code for X = LITERAL - Y
12196 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12197 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
12198 sprintf() in line 1267.
12200 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12201 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
12204 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12205 Changes to aslink (All the changes are marked with 'JCF'):
12207 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
12210 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
12211 area BSEG. Also moves, if possible, the DATA area down into the internal
12212 ram so more space is available.
12214 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
12217 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
12218 not bytes. Function summary() which creates a memory usage summary
12219 file with extension .mem. Reports of overlaping stack and small stack
12220 size. If the space for the stack is less than 16 bytes aslink trows a
12223 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
12224 the 8051. Option 'y' for memory summary output file.
12226 Changes to sdcc (All the changes are marked with 'JCF'):
12228 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
12230 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
12231 overlaying area for it (uses RegBankUsed[4]).
12233 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
12234 bank zero as used by default. By default aslink locates the stack
12235 (equivalent to --stack-after-data). Pass option 'y' to aslink for
12236 the creation of the .mem file. Delegates the allocation of data area
12237 to aslink (it is not longer 0x30 by default). If --stack-loc passes
12238 the begining of the stack area to aslink.
12240 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
12241 glue() in SDCCglue.c creates an area for it.
12243 2002-09-03 Borut Razem <borut.razem AT siol.net>
12244 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
12245 sdcc/src/pic/glue.c:
12246 introduced atexit() handler for teporay files removal in case of
12247 errors, assertions, ...
12249 2002-08-29 Borut Razem <borut.razem AT siol.net>
12250 * sdcc/support/cpp2/auto-host_vc_in.h:
12251 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
12252 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
12253 Maybe there is a similar problem with BORLANDC? It should be checked!
12255 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
12256 corrected improper use of assert: the assignment to clr variable was done inside the assert.
12257 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
12258 was not executed, and the compiler (cl) launched a warning:
12259 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
12261 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
12262 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
12264 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
12265 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
12267 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12268 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
12269 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
12270 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12271 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
12272 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
12273 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
12274 - added Release configuration in VS projects
12275 - review of compiler an linker options
12276 - VC .exe files are generated in bin_vc directory, not to interfere
12277 with binaries generated from other projects (cygwin, mingw, bcc ...)
12279 * sdcc/src/yacc.dsp: added
12281 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
12282 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
12283 and insert the version number definitions from .version
12285 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
12287 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
12288 added - genarate auto-host.h using auto-host_vc_in.h as template
12291 removed from CVS, generated automatically
12293 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
12294 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
12296 2002-08-11 Borut Razem <borut.razem AT siol.net>
12297 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
12299 2002-08-10 Borut Razem <borut.razem AT siol.net>
12300 * src/SDCCmain.c (main):
12301 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
12302 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
12303 The consequence was that some temporary files were not removed.
12306 unification of code in functions tempfilename() and tempfile():
12307 function tempnam() is defined in Visual Studio 6.0 and .NET
12309 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
12311 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12312 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
12313 - removed compiler command line option /WX: Treats all warnings as errors
12314 - update a list of source files, included into the project
12316 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12317 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
12318 changed project type to Generic Project so that can be correcly converted to VS.NET project
12320 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
12322 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
12324 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
12326 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
12327 added return 0 statements after assert() to make compiler happy
12329 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
12330 added newline in the def file to keep MSC compiler satisfied
12332 * sdcc/src/z80/gen.c:
12333 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
12334 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
12335 - solved MSC error in function aopDump()
12337 * sdcc_vc.h: define PREFIX as "\\sdcc"
12339 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
12340 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
12342 2002-06-22 Scott Dattalo <scott AT dattalo.com>
12343 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
12344 - Rewrote the register banking algorithm.
12345 - Added pCode live-range analysis to registers (for now, only non-used and
12346 singly-used registers optimized away)
12348 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
12350 * support/scripts/inc2h.pl Kevin L. Pauba <klpauba AT cox.net> submitted this perl script for converting MicroChip include files into SDCC Pic include files.
12352 2002-05-10 Scott Dattalo <scott AT dattalo.com>

12365 2002-04-15 Michael Hope <michaelh AT vroom>
12367 * device/lib/z80/printf.c (sprintf): Added.
12369 * src/z80/ralloc.c (packRegisters): Disabled pack HL use for GB as it's broken.
12371 * src/z80/peeph.def: Added transpose redundent load rule.
12373 * src/z80/main.c: Added force callee saves for jaune.
12375 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
12377 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
12379 2002-03-28 Johan Knol <johan AT balder>
12381 * src/SDCCval.c: fixed bug #532436
12383 2002-03-14 Scott Dattalo <scott AT dattalo.com>
12385 Added "char *Processor" field to the port structure.
12388 Added -p option. Allows port dependent processor to be specified.
12391 Initialized the new field char *Processor field to NULL in all ports
12394 Compiler generated registers for interrupt context saving
12395 were not getting allocated.
12397 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
12400 Fixed left shift. Will promote the left side of a left shift
12401 if a) left shifting more than size of operand or b) when assigned
12402 to something size > size of left side
