1425 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1427 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1428 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1430 One basic decision: e.g. src/clean.mk includes further files. In order
1431 to make this work there are two solutions:
1432 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1433 run configure on them. This way they can use
1434 'include $(srcdir)/port-clean.mk'
1435 - always include clean.mk by the Makefile at the same level. To avoid
1436 that `make clean` tries to include and build Makefile.dep the
1437 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1438 implemented, because now even `make uninstall` doesn't create
1439 Makefile.in. clean.mk could be eliminated by pasting it in
1442 * debugger/mcs51/Makefile.in: build own objects from library sources
1443 (SLIB, SDCC) in current directory
1445 * configure, configure.in: renamed --disable-device-lib-build in
1446 --disable-device-lib; added --enable-doc, the required tools are
1447 searched by configure; added result message; the toolchain for the
1448 belonging ports are now only built, if the port is enabled.
1450 * support/regression/*: all output is written in directory gen, because
1451 the fwk and ports directories don't livet in the build tree using vpath
1453 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1454 --disable-device-lib, added --enable-doc, added section VPATH
1456 * sim/ucsim/configure.in,
1457 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1458 z80 are enabled by default
1460 2006-04-24 Raphael Neider <rneider AT web.de>
1462 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1463 to config word, "pic14_"-prefixed some extern functions
1464 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1465 config word has been found
1466 * src/pic/device.h: added prototypes
1467 * src/pic/pcode.c: added "pic14_"-prefix where needed

1484 fixes #1469504 and #1474602,
1485 (pCodeRegOptimizeRegUsage): fixed typo in comment

1489 * device/examples/main8051.c: deleted - it was removed from CVS

1733 and enabled nesting of critical functions though not for gbz80
1734 (genCritical, genEndCritical): added functions
1735 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1736 * src/z80/mappings.i: added "ei" to all mappings

1745 2006-03-16 Raphael Neider <rneider AT web.de>
1747 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
1748 the left operand is shorter than the result (c* = lit-c* + int),
1750 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1753 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1755 * src/.version: increased version number to 2.5.5
1756 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1757 linking is done manually in pic16 port's _linkEdit,
1758 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1759 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1760 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1761 allocate asmop as AOP_ACC,
1762 (aopForRemat): added parameter 'bool result' in function declaration,
1763 (pic16_aopGet): return AOP_ACC when accessing WREG,

1775 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1776 call to allocReg, not by manually allocating a new one,
1777 (pic16_assignRegisters): now before going through the register
1778 allocating functions mark all registers as free. This eliminates some
1779 side effects resulting from peephole parser done earlier in the backbone

1834 made the linker quiet
1836 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
1838 * src/pic16/gen.c (genPcall): fixed bug #1443644
1839 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1840 which dumps before the function entry point a data byte which represents
1841 the number of the local variables used by the specified function, added
1842 'xinst' for initial support for Extended Instruction Support,
1843 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1844 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1845 port->fun_prefix anymore (may change later),

1860 (deassignLRs): *** perhaps the most important change, old 'for' code
1861 (commented out for reference), didn't account for some registers which
1862 were left marked 'not free' after a pointer operation. The change
1863 reduces register usage a lot in some cases

4138 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
4139 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
4140 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
4141 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
4142 always available in leading double underscore form. The C99 support is

4221 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
4223 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
4225 * device/lib/printf_large.c: removed inline assembly for portability and
4226 readability. Use printf_fast if speed or size are more important.
4227 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4228 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4230 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4232 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4233 prevent compiler warning
4235 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4237 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4238 moved to level 0 and declared as static. Also they are explicit
4239 placed in access bank. This was necessery because some times they
4240 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4241 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4242 optimizations. Currently only compare to unsigned char is implemented,
4243 * src/pic16/gen.c: added fReturnIdx array,
4244 * (struct resolvedIfx) is moved to gen.h and made public,
4245 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4246 * (aopForSym): added an optimization to directly store in stack of
4247 the operand of a SEND iCode,
4248 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4249 but as registers instead (AOP_REG) using the fReturnIdx array,
4250 * (pic16_freeAsmop): remove the freed register from the
4251 _G.sregsAlloc field,
4252 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4253 a compare of 'WREG',
4254 * (pic16_popGetTempRegCond): changed function prototype, now
4255 function takes also a bitVector argument v which holds the current
4256 set of registers that are allocated for stack access by aopForSym,
4257 registers allocated in aopForSym for accessing stack symbols are not
4258 any more part of the functions usedRegs field,
4259 * (genCall): some times aopOp is called for a stack variable to be
4260 send, aopForSym might perform the push, if this is true make sure
4261 that genCall doesn't push the variable twice by testing _G.resDirect,
4262 * (genFunction): changed testing for unspecified interrupt number
4263 from 256 to INTNO_UNSPEC,
4264 * modified selection scheme of frame pointer generation. Previously
4265 if function did use local registers a frame pointer was generated,
4266 now a frame pointer is generated only if function has arguments
4267 (that need PLUSW2 register access), or has stack arguments, or the
4268 compiler is not instructed to omit the frame pointer,
4269 * (genEndFunction): before restoring local registers that were saved
4270 in the function preamble, also restore the registers that *might*
4271 have been allocated for stack access,
4272 * (genRet): removed some old comments,
4273 * (genCmp, the active (RN's) version): added a call to the
4274 pic16_genCmp_special function to perform the compare with a more
4275 robust and optimized way,
4276 * (genInline): a feature has been added in inline code generation,
4277 which allows a wildcard variable substitution when writing inline
4278 assembly. Code is incomplete and experimental therefore undocumented,
4279 * (genCast): changed order of aopOp for result and right to allow
4280 aopForSym to directly load the result if possible,
4281 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4282 perform an optimized compare on some selected special occasions,
4283 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4284 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4285 generate an IVT any more,
4286 * src/pic16/main.c (pic16_optionsTable): added command line option
4288 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4289 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4291 * src/pic16/NOTES: Raphael Neider added in list of active developers
4292 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4293 jumptable_end to prevent bug #,
4294 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4295 inCond and outCond fields,
4296 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4297 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4298 turn off register spilling,
4299 * (packRegsForOneUse): synced with other ports' versions although it
4300 is not used currently,
4301 * (pic16_packRegisters): added an optimization while reading
4302 structure bitfields, some registers may be saved (malloc code is
4303 decreased by 80 bytes)
4305 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4307 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4308 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4309 this can be optimized more?
4311 2005-03-10 Raphael Neider <rneider AT web.de>
4313 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,

4949 Adding support for replacing ljmps with sjmps in jumptables
4950 generated for switch statements. For now you need to set the
4951 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4952 Now 4 algorithms for mcs51 jumptable generation are used:
4953 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4954 addresses loaded pc-relative for up to 112 cases and stack-pushing
4955 target addresses loaded with offset from dptr for up to 256 cases.

4987 * added libc directory. The current version of LibC contains string
4988 functions, ctype functions and macros and some functions of the
4989 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4990 be extensively tested in the future. Standard disclaimer here.
4991 Library is not automatically build yet. But one can build it by
4992 invoking 'make' inside the libc directory.

5003 * (pic16_storeForReturn): optimized return of 0,
5004 * (genCmp): experimental code for new genCmp which uses PIC18's
5005 special compare&skip instructions. Initial tests fail some times
5006 with variables grater than 1 byte in size, so new code is disabled,
5007 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5009 * (genCast): began a fix to optimize the casting of a bit to another
5010 bit, now assigning a bitfield to another bitfield will fail, sorry,

5019 and 1 for banking instruction,
5020 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
5021 caused stop processing pCodes after a inline assembly block,
5022 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

5024 registers when it shouldn't,
5025 * src/pic16/ralloc.c (allocReg): add preliminary support for
5026 supporting a limited set of temporary registers,
5028 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8036 loaded with the linker search paths (-L arguments) and the libraries
8037 to be linked with the current source (-l arguments). Changes
8038 currently will affect only the pic16 port.
8039 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8040 include path the port specific paths and port specific libraries,
8041 * gplink command now contains the $3 argument,
8042 * src/pic16/device.h,

8059 Documenting changes from previous commits.
8060 * configure.in (version 1.56),
8061 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8062 when generating output files to configure the pic16 library,
8063 but now I've commented it out, since gputils aren't installed in the
8064 SF compile farm, so library won't compile
8066 * device/lib/Makefile.in (version 1.56): initially I've added in
8067 target 'all' the prerequestive 'model-pic16' so it compiled the
8068 pic16 library, but now I've commented it out for the same reasons
8070 * added targets 'model-pic16' and 'objects-pic16' to compile the
8072 * added target 'port-specific-objects-pic16' to handle the
8073 generated libraries and copy them into the build/ directory
8074 * added target 'clean-intermediate-pic16' to clean intermediate
8075 files into pic16 directory
8076 * in target 'installdirs' added line to create directory pic16 in

8080 added lines to copy all header files to installation path,
8081 * in target 'installdirs' added line create directory for pic16
8082 headers in the installation path

8322 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
8323 LEFT_OP (left shift)
8325 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8327 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
8328 (default behaviour).
8330 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8332 A python script to validate compiler diagnostic messages. It can be
8333 used to verify that sdcc complains about bad c source code and
8334 gives a good location of the error.
8335 * support/valdiag/Makefile,
8336 * support/valdiag/valdiag.py,
8337 * support/valdiag/tests/*
8339 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8341 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
8342 * src/SDCCsymt.c (newEnumType),
8344 * support/Util/SDCCerr.c,
8345 * support/Util/SDCCerr.h: fixed bug #871258 and some other unreported
8347 * support/regression/tests/enum.c: added test for enum values that
8348 require at least 2 bytes of storage.
8350 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8352 * src/common.h: added ifndef/define/endif macros
8353 around the header file.
8354 Bug reported from Jesus Calvino-Fraga
8356 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8358 * sdcc.spec: updated
8359 * device/include/Makefile.in: don't install CVS directories
8360 * device/lib/Makefile.in: added removal of CVS directories after install
8361 * doc/Makefile: fixed install, added local_icons
8362 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8363 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8364 * src/ds390/gen.c (genRightShift): fixed bug #870788
8365 * src/SDCCast.c (decorateType): fixed bug #870781
8367 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8369 PIC16 port related changes:
8370 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8371 added variable stackPos,
8373 * gen.c: genCall, assignResultValue: added support for
8374 pushing/retrieving function parameters to/from stack,
8375 genFunction,genEndFunction: setup stack frame for the
8377 genAddrOf: will be changed according to bug 863624
8379 * added files genutils.c and genutils.h which contain gen*
8380 debugged and optimised functions extracted from gen.c
8382 * glue.c: added variable 'externs' which holds extern symbols,
8383 pic16emitRegularMap: is modified to properly handle relocatable
8384 symbols under the new scheme,
8385 pic16createInterruptVect: is modified
8386 pic16printPublics: is modified to emit 'global' assembler directives,
8387 added pic16_printExterns to print extern symbols,
8388 pic16glue: initializes stack/frame pointer in the beginning of
8389 the assembly output. Temporary hack, will be corrected later,
8390 because gplink yet does not support stack and SDCC does not
8391 yet support a type of crt0.o object to create the final binary.
8393 * Removed many lines that contain 8051 legacy code.
8394 * The code is finally placed under a 'code' directive.
8395 * Added port specific options.
8397 * _process_pragma: simplified since now we do not need *special*
8398 include file to define SFR registers. But a separate header
8399 will be needed. This will be developed later.
8400 * _pic16_parseOptions: added, parses port specific options:
8401 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8402 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8403 --preplace-udata-with=
8405 * _pic16_setDefaultOptions: modified to initialize section names,
8406 but hack is temporarly out of order since it needs improvement.
8407 * _pic16_genAssemblerPreamble: configuration words are emitted by
8408 their address instead of their name. This part is incomplete and
8409 supports only the 18Fxx2 devices. Other devices will emit an error
8410 during assembly since they do not contain the same set of config
8412 * _pic16_genIVT: is modified,
8414 * pcode.c: added definitions for some hardware registers that are needed
8416 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8417 All PCI entries are updated. Now LFSR is supported.
8418 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8419 * added pic16_newpCodeOpLit2 to support instructions with
8420 two literal arguments
8421 * pic16_pCode2str: corrected code that emits assembler instructions
8422 with two literal operands and those that have an access bit modifier
8423 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8424 this fixes a bug which caused some labels to be lost, when an
8425 assembler directive was added, i.e. banksel,
8426 * pic16_FixRegisterBanking: improved logic that causes the insertion
8428 * InlineFunction: functions that are called once, are not any more
8429 inlined. This can be a port option in the future,
8431 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8433 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8434 hold the corresponding uninitialized symbols,
8435 * pic16_allocProcessorRegister: registers have explicit marked the
8437 * pic16_allocInternalRegister: registers are explicit marked as
8439 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8440 processing list, so bit registers were lost,
8443 * ralloc.h: added field 'accessBank' and original symbol operand
8444 in register definition,
8445 * removed the field isMapped from register definition,
8447 ** Several functions have been removed from various sources:
8448 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8449 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8450 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8451 pic16_assignRelocatableRegisters
8453 ** others have been introduced:
8454 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8455 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8457 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8459 * support/scripts/inc2h.pl: changed definition of BIT_AT
8460 to emit 'sbit at' instead of 'bit at'. This was a request.
8462 PIC16 port related preliminary changes:
8463 * gen.c: prefixed function popRegFromString with
8464 pic16_ and all references to it corrected
8465 * pcode.c: all pic16_pc_* hardware registers prefixed
8466 with underscore (_),
8467 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8468 * ralloc.c: newReg(): when register is REG_SFR then
8469 set address to rIdx,
8470 pic16_allocProcessorRegister(): marks register wasUsed=0
8471 pic16_writeUsedRegs(): added a call to assign processor
8472 registers via pic16_assignFixedRegisters
8474 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8476 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8477 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8478 variables in unused register banks. Also the SSEG is placed
8479 wherever there is enough space for it, and IDATA can be anywhere
8480 in internal RAM. For now compile using -Wl-Y[stack_size].
8481 The mem file is different for this option as well, since it
8482 makes no sense of talking about DSEG lenght.
8484 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8486 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8487 in certain cases, e.g. when ROM assignment, patch provided
8488 from Albert den Haan.
8490 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8633 * src/mcs51/peephole.def,
8634 * src/ds390/peephole.def: using the atomic test and clear instruction jbc

8646 multiply defined with mismatching "at" address.
8648 2003-12-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8650 * src/ds390/main.c (PORT tininative_port): fixed bug #858416

8729 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8731 * src/SDCCast.c (decorateType): disabled a transformation I added in
8732 revision 1.188 (access to fields of a structure at an absolute address);
8733 it breaks with bitfields, extern declarations, and gcse analysis.
8734 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
8735 could be assigned through a pointer, so don't complain.
8736 * src/SDCCast.c (astErrors),
8738 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

9373 * src/SDCCsymt.c (sclsFromPtr),
9375 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
9376 support for standard C idiom of memory mapped variables; for
9377 example, *((xdata int*)0x1234) = 1 is now internally equivalent
9378 to xdata int at 0x1234 tempvar = 1.
9379 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
9380 provided by Akiya ISHIDA

9396 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9398 Fixed bug #621531 (const & volatile confusion in the type chain).
9399 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
9400 refer to the const or volatile state of the pointer itself.

9465 pcodeflow.c, pcodeflow.h, pcode.h, pcodepeep.c, pcoderegs.c,
9466 pcoderegs.h, ralloc.c, ralloc.h
9467 * main.c: added top header and GPL license notice

9491 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
9492 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
9493 fetching of the pointer
9494 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
9495 copied from genNearPointerSet()
9496 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
9497 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
9498 If they pop r0/r1 they must be called in the opposite order than aopOp().
9499 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
9500 (resp. --stack-auto), prepared for --xstack

9511 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
9513 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9514 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9515 type for bits was changed. It resulted in bit variables becoming
9516 global, which is not permitted in PIC 14 assembly output.
9518 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9520 * doc/sdccman.lyx: various additions and updates. Rearranged sections

9533 A few small changes that speed up the peephole optimizer.
9537 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9539 Try to make the peephole optimizer smarter by maintaining
9540 an association between the assembly source code and the
9541 iCodes that originated them. Put this information to use
9542 with a new peephole rule condition "notVolatile" so that
9543 the rules can be aggressive yet still safe.
9548 * src/mcs51/peeph.def
9550 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9554 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9555 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9556 if the left or right operand symbols have the accuse flag set.
9558 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9560 Changed the type of the result of the ! (NOT) operator to char;
9561 previously it returned the same type as the source. This allows
9562 us to eliminate all the genFloatNot functions (all of its target
9563 implementations were very buggy) since !float can use the same

9575 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9576 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9577 during interrupts. Ensure WSAVE is located at a shared bank address.
9578 2. Fixed page selection in some places
9579 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9580 the registers name strings.
9581 4. Fixed "signed / unsigned compare" compiler warnings.
9582 5. The PIC port manages its own allocation of the general purpose
9583 registers, but makes no attempt to reuse them. As a result when
9584 compiling it soon runs out of general purpose registers. Some
9585 additional code was added to the files pcode.c and device.c to walk
9586 through the function call tree and rename the registers so that they
9596 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9597 genPlus() & genMinus() when the result is the same as left or right
9599 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9603 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9605 Made bitfield a distinct type from bit so that bitfields
9606 convert as per ANSI C and bits retain their traditional
9607 boolean style behaviour. Implemented bitfield support in
9615 * src/ds390/gen.c: bit v bitfield split
9616 * src/z80/gen.c: New support for bitfields
9617 * support/regression/tests/bitfields.c: reenabled z80,
9620 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9622 Rules 246.x, 247.x relate to bitfields, the others speed up
9623 access to xdata mapped I/O devices.
9625 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9627 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9629 Cleaned up genPackBits and genUnpackBits and added two helper
9630 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9631 for literal assignments in genPackBits (thanks to Frieder for
9637 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9639 Fixed bug #748310 (pointer to function type mishandled when the
9640 function name is omitted). Also fixed a SIGSEGV when a function
9641 attribute (reentrant, etc) is used on a non-function or on a
9642 function but misplaced before the parameter list.
9644 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9646 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
9647 * support/Util/SDCCerr.h,
9648 * support/Util/SDCCerr.c: Added func attr misuse error msg

9669 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9671 Made the constant following the "interrupt" keyword optional. If
9672 omitted, the function will not automatically be given an entry
9673 in the interrupt vector table (similar to #pragma NOIV, but
9674 less syntacticly kludgy). The interrupt number is also now
9675 range checked. Also fixed a bug in the high order bit example

9689 * src/SDCCicode.c (operandOperation): rewritten some ops
9690 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
9691 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9693 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9694 be re-activated by defining REDUCE_LITERALS)
9695 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
9696 unsigned, but are signed by default
9697 * src/SDCCval.c (constVal): rearranged
9698 * src/SDCCval.c (valMod): preliminary fix
9699 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9741 constants are unsigned; added recognition of "u" flag for unsigned
9742 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
9743 * src/SDCCval.c (valDiv, valMod): fixed signdness
9744 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
9745 signedness of modulo, left and right shift

10206 messages from optionsTable when a port is not configured, added
10207 support for the PIc16 port in the ports table, when executing
10208 the compiler with no port specified on command line, a default
10209 port is selected with the new macro DEFAULT_PORT which is
10210 defined in port.h, in setDefaultOptions() linkOptions is removed
10211 from initialization assignment, since now it is a set,
10212 parseCmdLine uses setParseWithComma for linkOptions, in
10213 linkEdit() linkOptions are accessed with new function indexSet()
10214 which returns the i'th item of a set variable. See SDCCset.c, in
10215 linkEdit() when calling buildCmdLine(), added linkOptions as
10216 last argument. Now users can pass arguments to gplink via the
10217 -Wl option, main() uses pic16glue() to glue up pic16 programs

10231 gpasm complaining and test the linkage with gplink, _linkCmd and
10232 _asmCmd changed to be more gplink and gpasm friendly
10233 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10234 produced an error when parsed, peep rule 12 is added to utilize
10235 movff, but it is commented out since the pCode does not support
10236 yet a command with 2 address arguments

11260 * src/SDCCast.c (decorateType): fixed bug #600035
11262 2003-01-07 Bernhard Held <bernhard AT bernhardheld.de>
11263 * as/mcs51/lkmem.c: added several l-modifiers to printf to remove warnings
11264 * as/mcs51/lkaomf51.c: #include <ctype.h> to remove warnings

11275 * src/SDCCicode.c: fixed array add
11277 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
11278 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
11279 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
11281 2003-01-04 <johan AT balder>

11285 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11286 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
11288 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
11289 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

11292 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
11293 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
11295 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
11296 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
11298 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
11299 * src/mcs51/main.c: removed {bindir}{sep} from aslink
11301 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11303 * in /sdcc/as/mcs51/ changed these files in order to create an
11304 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11305 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11306 following files to include the previous two files: aslink.dsp,
11307 Makefile.aslink, Makefile.bcc, and Makefile.in.
11309 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11310 .adb instead of .cdb
11312 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11314 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11315 value from option --iram-size.
11317 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11319 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11322 2002-09-18 <wiml AT hhhh.org>
11324 * SDCClrange.h: exposed setFromRange() and setToRange()
11325 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11326 packRegsForAccUse() (bug 542397)
11327 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11328 multiple times and emitting the fetch operations more than once
11329 added aopGetUsesAcc() function to allow binary operators to
11330 fetch their operands in the correct order; made genMinus() emit
11331 compact code for X = LITERAL - Y
11333 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11334 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11335 sprintf() in line 1267.
11337 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11338 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11341 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11342 Changes to aslink (All the changes are marked with 'JCF'):
11344 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11347 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11348 area BSEG. Also moves, if possible, the DATA area down into the internal
11349 ram so more space is available.
11351 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11354 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11355 not bytes. Function summary() which creates a memory usage summary
11356 file with extension .mem. Reports of overlaping stack and small stack
11357 size. If the space for the stack is less than 16 bytes aslink trows a
11360 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11361 the 8051. Option 'y' for memory summary output file.
11363 Changes to sdcc (All the changes are marked with 'JCF'):
11365 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11367 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11368 overlaying area for it (uses RegBankUsed[4]).
11370 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11371 bank zero as used by default. By default aslink locates the stack
11372 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11373 the creation of the .mem file. Delegates the allocation of data area
11374 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11375 the begining of the stack area to aslink.
11377 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11378 glue() in SDCCglue.c creates an area for it.
11380 2002-09-03 Borut Razem <borut.razem AT siol.net>
11381 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11382 sdcc/src/pic/glue.c:
11383 introduced atexit() handler for teporay files removal in case of
11384 errors, assertions, ...
11386 2002-08-29 Borut Razem <borut.razem AT siol.net>
11387 * sdcc/support/cpp2/auto-host_vc_in.h:
11388 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11389 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11390 Maybe there is a similar problem with BORLANDC? It should be checked!
11392 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11393 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11394 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11395 was not executed, and the compiler (cl) launched a warning:
11396 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11398 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11399 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11401 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11402 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11404 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11405 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11406 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11407 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11408 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11409 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11410 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11411 - added Release configuration in VS projects
11412 - review of compiler an linker options
11413 - VC .exe files are generated in bin_vc directory, not to interfere
11414 with binaries generated from other projects (cygwin, mingw, bcc ...)
11416 * sdcc/src/yacc.dsp: added
11418 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11419 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11420 and insert the version number definitions from .version
11422 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11424 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11425 added - genarate auto-host.h using auto-host_vc_in.h as template
11428 removed from CVS, generated automatically
11430 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11431 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11433 2002-08-11 Borut Razem <borut.razem AT siol.net>
11434 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11436 2002-08-10 Borut Razem <borut.razem AT siol.net>
11437 * src/SDCCmain.c (main):
11438 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11439 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11440 The consequence was that some temporary files were not removed.
11443 unification of code in functions tempfilename() and tempfile():
11444 function tempnam() is defined in Visual Studio 6.0 and .NET
11446 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11448 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11449 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11450 - removed compiler command line option /WX: Treats all warnings as errors
11451 - update a list of source files, included into the project
11453 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11454 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11455 changed project type to Generic Project so that can be correcly converted to VS.NET project
11457 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11459 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11461 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11463 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11464 added return 0 statements after assert() to make compiler happy
11466 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11467 added newline in the def file to keep MSC compiler satisfied
11469 * sdcc/src/z80/gen.c:
11470 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11471 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11472 - solved MSC error in function aopDump()
11474 * sdcc_vc.h: define PREFIX as "\\sdcc"
11476 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
11477 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

11480 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
11481 - Rewrote the register banking algorithm.
11482 - Added pCode live-range analysis to registers (for now, only non-used and
11483 singly-used registers optimized away)
11485 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
11487 * 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.

11516 2002-03-28 Johan Knol <johan AT balder>
11518 * src/SDCCval.c: fixed bug #532436
11520 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11522 Added "char *Processor" field to the port structure.
11525 Added -p option. Allows port dependent processor to be specified.
11528 Initialized the new field char *Processor field to NULL in all ports
11531 Compiler generated registers for interrupt context saving
11532 were not getting allocated.
11534 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
11537 Fixed left shift. Will promote the left side of a left shift
11538 if a) left shifting more than size of operand or b) when assigned
11539 to something size > size of left side
11541 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11543 tons of changes. Register allocation has been
11544 rewritten. Added customization for the various PICs. Flow
11545 analysis is restructured. ...
11547 * src/pic/device.h:
11550 * src/pic/device.c:
11551 Added. device.c is a PIC port hack to accomodate variations
11554 2002-03-13 Michael Hope <michaelh AT vroom>
11556 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
11558 2002-03-04 johanknol <johanknol AT manik>
11560 * /src/SDCCval.c: fixed
11562 const unsigned char arr[][2] = { { 0, 1 } };

11649 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
11651 * sdcc/src/SDCCloop.c:
11652 Previous fix was not good. basic blocks that have "break" or "return" are
11653 not really partof a loop , but live ranges used in these blocks should
11654 be live thru the entire loop, so set partOfLoop but don't add them to
