1407 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1409 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1410 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1412 One basic decision: e.g. src/clean.mk includes further files. In order
1413 to make this work there are two solutions:
1414 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1415 run configure on them. This way they can use
1416 'include $(srcdir)/port-clean.mk'
1417 - always include clean.mk by the Makefile at the same level. To avoid
1418 that `make clean` tries to include and build Makefile.dep the
1419 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1420 implemented, because now even `make uninstall` doesn't create
1421 Makefile.in. clean.mk could be eliminated by pasting it in
1424 * debugger/mcs51/Makefile.in: build own objects from library sources
1425 (SLIB, SDCC) in current directory
1427 * configure, configure.in: renamed --disable-device-lib-build in
1428 --disable-device-lib; added --enable-doc, the required tools are
1429 searched by configure; added result message; the toolchain for the
1430 belonging ports are now only built, if the port is enabled.
1432 * support/regression/*: all output is written in directory gen, because
1433 the fwk and ports directories don't livet in the build tree using vpath
1435 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1436 --disable-device-lib, added --enable-doc, added section VPATH
1438 * sim/ucsim/configure.in,
1439 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1440 z80 are enabled by default
1442 2006-04-24 Raphael Neider <rneider AT web.de>
1444 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1445 to config word, "pic14_"-prefixed some extern functions
1446 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1447 config word has been found
1448 * src/pic/device.h: added prototypes
1449 * src/pic/pcode.c: added "pic14_"-prefix where needed
1450 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
1452 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

1471 * device/examples/main8051.c: deleted - it was removed from CVS

1740 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1741 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,

1757 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1758 call to allocReg, not by manually allocating a new one,
1759 (pic16_assignRegisters): now before going through the register
1760 allocating functions mark all registers as free. This eliminates some
1761 side effects resulting from peephole parser done earlier in the backbone

1811 * support/regression/tests/array.c: added parenthesis, made arrays unsigned
1813 2006-03-06 Borut Razem <borut.razem AT siol.net>
1815 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
1816 made the linker quiet
1818 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
1820 * src/pic16/gen.c (genPcall): fixed bug #1443644
1821 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1822 which dumps before the function entry point a data byte which represents
1823 the number of the local variables used by the specified function, added
1824 'xinst' for initial support for Extended Instruction Support,
1825 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1826 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1827 port->fun_prefix anymore (may change later),
1828 (genFunction, genEndFunction): do not store/restore local registers for
1829 _main (this should take care the --main-return command line option in
1831 (genOr): removed some legacy pic-port instructions,

1840 --extended or -y for Extended Instruction Support,
1841 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1842 (deassignLRs): *** perhaps the most important change, old 'for' code
1843 (commented out for reference), didn't account for some registers which
1844 were left marked 'not free' after a pointer operation. The change
1845 reduces register usage a lot in some cases

4120 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
4121 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
4122 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
4123 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
4124 always available in leading double underscore form. The C99 support is
4125 mostly missing, but it's a start.
4126 * support/regression/tests/bug-227710.c: fixed nonconforming use of
4127 reserved identifier "__data".
4129 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

4203 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
4205 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
4207 * device/lib/printf_large.c: removed inline assembly for portability and
4208 readability. Use printf_fast if speed or size are more important.
4209 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4210 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4212 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4214 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4215 prevent compiler warning
4217 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4219 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4220 moved to level 0 and declared as static. Also they are explicit
4221 placed in access bank. This was necessery because some times they
4222 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4223 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4224 optimizations. Currently only compare to unsigned char is implemented,
4225 * src/pic16/gen.c: added fReturnIdx array,
4226 * (struct resolvedIfx) is moved to gen.h and made public,
4227 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4228 * (aopForSym): added an optimization to directly store in stack of
4229 the operand of a SEND iCode,
4230 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4231 but as registers instead (AOP_REG) using the fReturnIdx array,
4232 * (pic16_freeAsmop): remove the freed register from the
4233 _G.sregsAlloc field,
4234 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4235 a compare of 'WREG',
4236 * (pic16_popGetTempRegCond): changed function prototype, now
4237 function takes also a bitVector argument v which holds the current
4238 set of registers that are allocated for stack access by aopForSym,
4239 registers allocated in aopForSym for accessing stack symbols are not
4240 any more part of the functions usedRegs field,
4241 * (genCall): some times aopOp is called for a stack variable to be
4242 send, aopForSym might perform the push, if this is true make sure
4243 that genCall doesn't push the variable twice by testing _G.resDirect,
4244 * (genFunction): changed testing for unspecified interrupt number
4245 from 256 to INTNO_UNSPEC,
4246 * modified selection scheme of frame pointer generation. Previously
4247 if function did use local registers a frame pointer was generated,
4248 now a frame pointer is generated only if function has arguments
4249 (that need PLUSW2 register access), or has stack arguments, or the
4250 compiler is not instructed to omit the frame pointer,
4251 * (genEndFunction): before restoring local registers that were saved
4252 in the function preamble, also restore the registers that *might*
4253 have been allocated for stack access,
4254 * (genRet): removed some old comments,
4255 * (genCmp, the active (RN's) version): added a call to the
4256 pic16_genCmp_special function to perform the compare with a more
4257 robust and optimized way,
4258 * (genInline): a feature has been added in inline code generation,
4259 which allows a wildcard variable substitution when writing inline
4260 assembly. Code is incomplete and experimental therefore undocumented,
4261 * (genCast): changed order of aopOp for result and right to allow
4262 aopForSym to directly load the result if possible,
4263 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4264 perform an optimized compare on some selected special occasions,
4265 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4266 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4267 generate an IVT any more,
4268 * src/pic16/main.c (pic16_optionsTable): added command line option
4270 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4271 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4273 * src/pic16/NOTES: Raphael Neider added in list of active developers
4274 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4275 jumptable_end to prevent bug #,
4276 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4277 inCond and outCond fields,
4278 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4279 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4280 turn off register spilling,
4281 * (packRegsForOneUse): synced with other ports' versions although it
4282 is not used currently,
4283 * (pic16_packRegisters): added an optimization while reading
4284 structure bitfields, some registers may be saved (malloc code is
4285 decreased by 80 bytes)
4287 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4289 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4290 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4291 this can be optimized more?
4293 2005-03-10 Raphael Neider <rneider AT web.de>
4295 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4296 genNearPointerGet): (hopefully) fixed access to bitfields via
4297 pointers (p->bitN = x; and x = p->bitN; failed)
4299 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
4301 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"
4303 2005-03-09 Raphael Neider <rneider AT web.de>

4307 2005-03-06 Maarten Brock <sourceforge.brock AT dse.nl>
4309 * src/SDCCicode.h: moved CRITICAL and ENDCRITICAL from SKIP_IC2 to SKIP_IC
4310 * src/mcs51/ralloc.c (willCauseSpill): added check for REG_BIT type,
4311 (regTypeNum): set REG_BIT type if necessary
4312 * src/mcs51/ralloc.h: added define REG_BIT, used to fix bug 1144613

4931 Adding support for replacing ljmps with sjmps in jumptables
4932 generated for switch statements. For now you need to set the
4933 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4934 Now 4 algorithms for mcs51 jumptable generation are used:
4935 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4936 addresses loaded pc-relative for up to 112 cases and stack-pushing
4937 target addresses loaded with offset from dptr for up to 256 cases.

4967 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4969 * added libc directory. The current version of LibC contains string
4970 functions, ctype functions and macros and some functions of the
4971 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4972 be extensively tested in the future. Standard disclaimer here.
4973 Library is not automatically build yet. But one can build it by
4974 invoking 'make' inside the libc directory.

4985 * (pic16_storeForReturn): optimized return of 0,
4986 * (genCmp): experimental code for new genCmp which uses PIC18's
4987 special compare&skip instructions. Initial tests fail some times
4988 with variables grater than 1 byte in size, so new code is disabled,
4989 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4991 * (genCast): began a fix to optimize the casting of a bit to another
4992 bit, now assigning a bitfield to another bitfield will fail, sorry,

5000 * (isBankInstruction): modified to return 0 for no banking instruction,
5001 and 1 for banking instruction,
5002 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
5003 caused stop processing pCodes after a inline assembly block,
5004 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
5005 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
5006 registers when it shouldn't,
5007 * src/pic16/ralloc.c (allocReg): add preliminary support for
5008 supporting a limited set of temporary registers,
5010 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5012 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
5013 genDataPointerSet): ensure assignments always copy in MSB to LSB
5015 (loadRegFromAop): recognize CLRH optimization,
5016 (genFunction): optimize RECEIVE iCodes in reentrant functions
5018 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5020 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

8018 loaded with the linker search paths (-L arguments) and the libraries
8019 to be linked with the current source (-l arguments). Changes
8020 currently will affect only the pic16 port.
8021 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8022 include path the port specific paths and port specific libraries,
8023 * gplink command now contains the $3 argument,
8024 * src/pic16/device.h,
8025 * src/pic16/device.c,: structure PIC_device is made public and
8026 renamed to PIC16_device, the same for variable Pics which is renamed

8041 Documenting changes from previous commits.
8042 * configure.in (version 1.56),
8043 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8044 when generating output files to configure the pic16 library,
8045 but now I've commented it out, since gputils aren't installed in the
8046 SF compile farm, so library won't compile
8048 * device/lib/Makefile.in (version 1.56): initially I've added in
8049 target 'all' the prerequestive 'model-pic16' so it compiled the
8050 pic16 library, but now I've commented it out for the same reasons
8052 * added targets 'model-pic16' and 'objects-pic16' to compile the
8054 * added target 'port-specific-objects-pic16' to handle the
8055 generated libraries and copy them into the build/ directory
8056 * added target 'clean-intermediate-pic16' to clean intermediate
8057 files into pic16 directory
8058 * in target 'installdirs' added line to create directory pic16 in

8324 * src/SDCCsymt.c (newEnumType),
8326 * support/Util/SDCCerr.c,
8327 * support/Util/SDCCerr.h: fixed bug #871258 and some other unreported
8329 * support/regression/tests/enum.c: added test for enum values that
8330 require at least 2 bytes of storage.
8332 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8334 * src/common.h: added ifndef/define/endif macros
8335 around the header file.
8336 Bug reported from Jesus Calvino-Fraga
8338 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8340 * sdcc.spec: updated
8341 * device/include/Makefile.in: don't install CVS directories
8342 * device/lib/Makefile.in: added removal of CVS directories after install
8343 * doc/Makefile: fixed install, added local_icons
8344 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8345 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8346 * src/ds390/gen.c (genRightShift): fixed bug #870788
8347 * src/SDCCast.c (decorateType): fixed bug #870781
8349 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8351 PIC16 port related changes:
8352 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8353 added variable stackPos,
8355 * gen.c: genCall, assignResultValue: added support for
8356 pushing/retrieving function parameters to/from stack,
8357 genFunction,genEndFunction: setup stack frame for the
8359 genAddrOf: will be changed according to bug 863624
8361 * added files genutils.c and genutils.h which contain gen*
8362 debugged and optimised functions extracted from gen.c
8364 * glue.c: added variable 'externs' which holds extern symbols,
8365 pic16emitRegularMap: is modified to properly handle relocatable
8366 symbols under the new scheme,
8367 pic16createInterruptVect: is modified
8368 pic16printPublics: is modified to emit 'global' assembler directives,
8369 added pic16_printExterns to print extern symbols,
8370 pic16glue: initializes stack/frame pointer in the beginning of
8371 the assembly output. Temporary hack, will be corrected later,
8372 because gplink yet does not support stack and SDCC does not
8373 yet support a type of crt0.o object to create the final binary.
8375 * Removed many lines that contain 8051 legacy code.
8376 * The code is finally placed under a 'code' directive.
8377 * Added port specific options.
8379 * _process_pragma: simplified since now we do not need *special*
8380 include file to define SFR registers. But a separate header
8381 will be needed. This will be developed later.
8382 * _pic16_parseOptions: added, parses port specific options:
8383 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8384 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8385 --preplace-udata-with=
8387 * _pic16_setDefaultOptions: modified to initialize section names,
8388 but hack is temporarly out of order since it needs improvement.
8389 * _pic16_genAssemblerPreamble: configuration words are emitted by
8390 their address instead of their name. This part is incomplete and
8391 supports only the 18Fxx2 devices. Other devices will emit an error
8392 during assembly since they do not contain the same set of config
8394 * _pic16_genIVT: is modified,
8396 * pcode.c: added definitions for some hardware registers that are needed
8398 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8399 All PCI entries are updated. Now LFSR is supported.
8400 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8401 * added pic16_newpCodeOpLit2 to support instructions with
8402 two literal arguments
8403 * pic16_pCode2str: corrected code that emits assembler instructions
8404 with two literal operands and those that have an access bit modifier
8405 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8406 this fixes a bug which caused some labels to be lost, when an
8407 assembler directive was added, i.e. banksel,
8408 * pic16_FixRegisterBanking: improved logic that causes the insertion
8410 * InlineFunction: functions that are called once, are not any more
8411 inlined. This can be a port option in the future,
8413 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8415 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8416 hold the corresponding uninitialized symbols,
8417 * pic16_allocProcessorRegister: registers have explicit marked the
8419 * pic16_allocInternalRegister: registers are explicit marked as
8421 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8422 processing list, so bit registers were lost,
8425 * ralloc.h: added field 'accessBank' and original symbol operand
8426 in register definition,
8427 * removed the field isMapped from register definition,
8429 ** Several functions have been removed from various sources:
8430 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8431 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8432 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8433 pic16_assignRelocatableRegisters
8435 ** others have been introduced:
8436 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8437 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8439 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8441 * support/scripts/inc2h.pl: changed definition of BIT_AT
8442 to emit 'sbit at' instead of 'bit at'. This was a request.
8444 PIC16 port related preliminary changes:
8445 * gen.c: prefixed function popRegFromString with
8446 pic16_ and all references to it corrected
8447 * pcode.c: all pic16_pc_* hardware registers prefixed
8448 with underscore (_),
8449 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8450 * ralloc.c: newReg(): when register is REG_SFR then
8451 set address to rIdx,
8452 pic16_allocProcessorRegister(): marks register wasUsed=0
8453 pic16_writeUsedRegs(): added a call to assign processor
8454 registers via pic16_assignFixedRegisters
8456 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8458 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8459 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8460 variables in unused register banks. Also the SSEG is placed
8461 wherever there is enough space for it, and IDATA can be anywhere
8462 in internal RAM. For now compile using -Wl-Y[stack_size].
8463 The mem file is different for this option as well, since it
8464 makes no sense of talking about DSEG lenght.
8466 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8468 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8469 in certain cases, e.g. when ROM assignment, patch provided
8470 from Albert den Haan.
8472 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8711 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8713 * src/SDCCast.c (decorateType): disabled a transformation I added in
8714 revision 1.188 (access to fields of a structure at an absolute address);
8715 it breaks with bitfields, extern declarations, and gcse analysis.
8716 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
8717 could be assigned through a pointer, so don't complain.
8718 * src/SDCCast.c (astErrors),
8720 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

9378 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9380 Fixed bug #621531 (const & volatile confusion in the type chain).
9381 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively

9474 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
9475 fetching of the pointer
9476 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
9477 copied from genNearPointerSet()
9478 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
9479 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

9493 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
9495 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9496 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9497 type for bits was changed. It resulted in bit variables becoming
9498 global, which is not permitted in PIC 14 assembly output.
9500 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9502 * doc/sdccman.lyx: various additions and updates. Rearranged sections

9515 A few small changes that speed up the peephole optimizer.
9519 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9521 Try to make the peephole optimizer smarter by maintaining
9522 an association between the assembly source code and the
9523 iCodes that originated them. Put this information to use
9524 with a new peephole rule condition "notVolatile" so that
9525 the rules can be aggressive yet still safe.
9530 * src/mcs51/peeph.def
9532 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9536 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9537 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9538 if the left or right operand symbols have the accuse flag set.
9540 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9542 Changed the type of the result of the ! (NOT) operator to char;
9543 previously it returned the same type as the source. This allows
9544 us to eliminate all the genFloatNot functions (all of its target
9545 implementations were very buggy) since !float can use the same
9548 * src/SDCCicode.c (ast2iCode): ! returns char

9557 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9558 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9559 during interrupts. Ensure WSAVE is located at a shared bank address.
9560 2. Fixed page selection in some places
9561 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9562 the registers name strings.
9563 4. Fixed "signed / unsigned compare" compiler warnings.
9564 5. The PIC port manages its own allocation of the general purpose
9565 registers, but makes no attempt to reuse them. As a result when
9566 compiling it soon runs out of general purpose registers. Some
9567 additional code was added to the files pcode.c and device.c to walk
9568 through the function call tree and rename the registers so that they
9578 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9579 genPlus() & genMinus() when the result is the same as left or right

9585 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9587 Made bitfield a distinct type from bit so that bitfields
9588 convert as per ANSI C and bits retain their traditional
9589 boolean style behaviour. Implemented bitfield support in
9597 * src/ds390/gen.c: bit v bitfield split
9598 * src/z80/gen.c: New support for bitfields
9599 * support/regression/tests/bitfields.c: reenabled z80,
9602 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9604 Rules 246.x, 247.x relate to bitfields, the others speed up
9605 access to xdata mapped I/O devices.
9607 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9609 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9611 Cleaned up genPackBits and genUnpackBits and added two helper
9612 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9613 for literal assignments in genPackBits (thanks to Frieder for
9619 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9621 Fixed bug #748310 (pointer to function type mishandled when the
9622 function name is omitted). Also fixed a SIGSEGV when a function
9623 attribute (reentrant, etc) is used on a non-function or on a
9624 function but misplaced before the parameter list.
9626 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9628 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
9629 * support/Util/SDCCerr.h,
9630 * support/Util/SDCCerr.c: Added func attr misuse error msg

9651 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9653 Made the constant following the "interrupt" keyword optional. If
9654 omitted, the function will not automatically be given an entry
9655 in the interrupt vector table (similar to #pragma NOIV, but
9656 less syntacticly kludgy). The interrupt number is also now
9657 range checked. Also fixed a bug in the high order bit example

9671 * src/SDCCicode.c (operandOperation): rewritten some ops
9672 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
9673 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9675 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9676 be re-activated by defining REDUCE_LITERALS)
9677 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
9678 unsigned, but are signed by default
9679 * src/SDCCval.c (constVal): rearranged
9680 * src/SDCCval.c (valMod): preliminary fix
9681 * src/SDCCval.c (valCastLiteral): use TYPE_* types

10187 added if/endif conditional macros to remove options help
10188 messages from optionsTable when a port is not configured, added
10189 support for the PIc16 port in the ports table, when executing
10190 the compiler with no port specified on command line, a default
10191 port is selected with the new macro DEFAULT_PORT which is
10192 defined in port.h, in setDefaultOptions() linkOptions is removed
10193 from initialization assignment, since now it is a set,
10194 parseCmdLine uses setParseWithComma for linkOptions, in
10195 linkEdit() linkOptions are accessed with new function indexSet()
10196 which returns the i'th item of a set variable. See SDCCset.c, in
10197 linkEdit() when calling buildCmdLine(), added linkOptions as
10198 last argument. Now users can pass arguments to gplink via the
10199 -Wl option, main() uses pic16glue() to glue up pic16 programs

10213 gpasm complaining and test the linkage with gplink, _linkCmd and
10214 _asmCmd changed to be more gplink and gpasm friendly
10215 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10216 produced an error when parsed, peep rule 12 is added to utilize
10217 movff, but it is commented out since the pCode does not support
10218 yet a command with 2 address arguments
10220 2003-05-18 <johan AT balder>
10222 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

11244 2003-01-07 Bernhard Held <bernhard AT bernhardheld.de>
11245 * as/mcs51/lkmem.c: added several l-modifiers to printf to remove warnings
11246 * as/mcs51/lkaomf51.c: #include <ctype.h> to remove warnings

11255 2003-01-06 <johan AT balder>
11257 * src/SDCCicode.c: fixed array add
11259 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
11260 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
11261 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
11263 2003-01-04 <johan AT balder>

11267 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11268 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
11270 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
11271 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

11274 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
11275 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
11277 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
11278 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
11280 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
11281 * src/mcs51/main.c: removed {bindir}{sep} from aslink
11283 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11285 * in /sdcc/as/mcs51/ changed these files in order to create an
11286 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11287 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11288 following files to include the previous two files: aslink.dsp,
11289 Makefile.aslink, Makefile.bcc, and Makefile.in.
11291 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11292 .adb instead of .cdb
11294 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11296 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11297 value from option --iram-size.
11299 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11301 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11304 2002-09-18 <wiml AT hhhh.org>
11306 * SDCClrange.h: exposed setFromRange() and setToRange()
11307 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11308 packRegsForAccUse() (bug 542397)
11309 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11310 multiple times and emitting the fetch operations more than once
11311 added aopGetUsesAcc() function to allow binary operators to
11312 fetch their operands in the correct order; made genMinus() emit
11313 compact code for X = LITERAL - Y
11315 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11316 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11317 sprintf() in line 1267.
11319 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11320 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11323 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11324 Changes to aslink (All the changes are marked with 'JCF'):
11326 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11329 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11330 area BSEG. Also moves, if possible, the DATA area down into the internal
11331 ram so more space is available.
11333 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11336 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11337 not bytes. Function summary() which creates a memory usage summary
11338 file with extension .mem. Reports of overlaping stack and small stack
11339 size. If the space for the stack is less than 16 bytes aslink trows a
11342 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11343 the 8051. Option 'y' for memory summary output file.
11345 Changes to sdcc (All the changes are marked with 'JCF'):
11347 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11349 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11350 overlaying area for it (uses RegBankUsed[4]).
11352 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11353 bank zero as used by default. By default aslink locates the stack
11354 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11355 the creation of the .mem file. Delegates the allocation of data area
11356 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11357 the begining of the stack area to aslink.
11359 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11360 glue() in SDCCglue.c creates an area for it.
11362 2002-09-03 Borut Razem <borut.razem AT siol.net>
11363 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11364 sdcc/src/pic/glue.c:
11365 introduced atexit() handler for teporay files removal in case of
11366 errors, assertions, ...
11368 2002-08-29 Borut Razem <borut.razem AT siol.net>
11369 * sdcc/support/cpp2/auto-host_vc_in.h:
11370 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11371 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11372 Maybe there is a similar problem with BORLANDC? It should be checked!
11374 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11375 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11376 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11377 was not executed, and the compiler (cl) launched a warning:
11378 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11380 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11381 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11383 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11384 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11386 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11387 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11388 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11389 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11390 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11391 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11392 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11393 - added Release configuration in VS projects
11394 - review of compiler an linker options
11395 - VC .exe files are generated in bin_vc directory, not to interfere
11396 with binaries generated from other projects (cygwin, mingw, bcc ...)
11398 * sdcc/src/yacc.dsp: added
11400 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11401 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11402 and insert the version number definitions from .version
11404 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11406 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11407 added - genarate auto-host.h using auto-host_vc_in.h as template
11410 removed from CVS, generated automatically
11412 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11413 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11415 2002-08-11 Borut Razem <borut.razem AT siol.net>
11416 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11418 2002-08-10 Borut Razem <borut.razem AT siol.net>
11419 * src/SDCCmain.c (main):
11420 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11421 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11422 The consequence was that some temporary files were not removed.
11425 unification of code in functions tempfilename() and tempfile():
11426 function tempnam() is defined in Visual Studio 6.0 and .NET
11428 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11430 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11431 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11432 - removed compiler command line option /WX: Treats all warnings as errors
11433 - update a list of source files, included into the project
11435 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11436 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11437 changed project type to Generic Project so that can be correcly converted to VS.NET project
11439 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11441 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11443 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11445 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11446 added return 0 statements after assert() to make compiler happy
11448 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11449 added newline in the def file to keep MSC compiler satisfied
11451 * sdcc/src/z80/gen.c:
11452 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11453 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11454 - solved MSC error in function aopDump()
11456 * sdcc_vc.h: define PREFIX as "\\sdcc"
11458 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
11459 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
11461 2002-06-22 Scott Dattalo <scott AT dattalo.com>
11462 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
11463 - Rewrote the register banking algorithm.
11464 - Added pCode live-range analysis to registers (for now, only non-used and
11465 singly-used registers optimized away)
11467 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
11469 * 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.
11471 2002-05-10 Scott Dattalo <scott AT dattalo.com>

11484 2002-04-15 Michael Hope <michaelh AT vroom>
11486 * device/lib/z80/printf.c (sprintf): Added.
11488 * src/z80/ralloc.c (packRegisters): Disabled pack HL use for GB as it's broken.
11490 * src/z80/peeph.def: Added transpose redundent load rule.
11492 * src/z80/main.c: Added force callee saves for jaune.
11494 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
11496 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
11498 2002-03-28 Johan Knol <johan AT balder>
11500 * src/SDCCval.c: fixed bug #532436
11502 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11504 Added "char *Processor" field to the port structure.
11507 Added -p option. Allows port dependent processor to be specified.
11510 Initialized the new field char *Processor field to NULL in all ports
11513 Compiler generated registers for interrupt context saving
11514 were not getting allocated.
11516 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
11519 Fixed left shift. Will promote the left side of a left shift
11520 if a) left shifting more than size of operand or b) when assigned
11521 to something size > size of left side
11523 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11525 tons of changes. Register allocation has been
11526 rewritten. Added customization for the various PICs. Flow
11527 analysis is restructured. ...
11529 * src/pic/device.h:
11532 * src/pic/device.c:
11533 Added. device.c is a PIC port hack to accomodate variations
11536 2002-03-13 Michael Hope <michaelh AT vroom>
11538 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
11540 2002-03-04 johanknol <johanknol AT manik>
11542 * /src/SDCCval.c: fixed
11544 const unsigned char arr[][2] = { { 0, 1 } };

11603 * src/z80/ralloc.c (packRegsForIYUse): Fixed fp bug where four byte operands were packed into IY.
11605 2002-03-01 <johan AT FRIJA>
11607 * src/SDCCglue.c (printIvalPtr): fixed bug #524211
11609 * src/SDCCast.c (decorateType): fixed bug #524209

11631 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
11633 * sdcc/src/SDCCloop.c:
11634 Previous fix was not good. basic blocks that have "break" or "return" are
11635 not really partof a loop , but live ranges used in these blocks should
11636 be live thru the entire loop, so set partOfLoop but don't add them to
11639 2002-02-21 <johan AT FRIJA>
11641 * src/SDCCcse.c: fixed bug #514308
11643 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
11646 Fixed BUG #519583. If a conditional block ended in a return/break
11647 statement inside a loop, it was not being considered part of the loop.
11649 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
11651 2002-02-10 Karl Bongers <karl AT turbobit.com>
