1421 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1422 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1424 One basic decision: e.g. src/clean.mk includes further files. In order
1425 to make this work there are two solutions:
1426 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1427 run configure on them. This way they can use
1428 'include $(srcdir)/port-clean.mk'
1429 - always include clean.mk by the Makefile at the same level. To avoid
1430 that `make clean` tries to include and build Makefile.dep the
1431 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1432 implemented, because now even `make uninstall` doesn't create
1433 Makefile.in. clean.mk could be eliminated by pasting it in
1436 * debugger/mcs51/Makefile.in: build own objects from library sources
1437 (SLIB, SDCC) in current directory
1439 * configure, configure.in: renamed --disable-device-lib-build in
1440 --disable-device-lib; added --enable-doc, the required tools are
1441 searched by configure; added result message; the toolchain for the
1442 belonging ports are now only built, if the port is enabled.
1444 * support/regression/*: all output is written in directory gen, because
1445 the fwk and ports directories don't livet in the build tree using vpath
1447 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1448 --disable-device-lib, added --enable-doc, added section VPATH
1450 * sim/ucsim/configure.in,
1451 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1452 z80 are enabled by default
1454 2006-04-24 Raphael Neider <rneider AT web.de>
1456 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1457 to config word, "pic14_"-prefixed some extern functions
1458 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1459 config word has been found
1460 * src/pic/device.h: added prototypes
1461 * src/pic/pcode.c: added "pic14_"-prefix where needed
1462 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
1464 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

1478 fixes #1469504 and #1474602,
1479 (pCodeRegOptimizeRegUsage): fixed typo in comment

1751 linking is done manually in pic16 port's _linkEdit,
1752 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1753 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,

1769 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1770 call to allocReg, not by manually allocating a new one,
1771 (pic16_assignRegisters): now before going through the register
1772 allocating functions mark all registers as free. This eliminates some
1773 side effects resulting from peephole parser done earlier in the backbone
1775 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

1797 (aopForSym, aopOp): increment asmop.allocated if reused,
1798 (freeAsmop): decrement asmop.allocated and check for zero instead of
1800 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
1801 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,
1802 genCmpLt, genAndOp, genOrOp, genAnd, genOr, genXor, genRRC, genRLC,

1825 2006-03-06 Borut Razem <borut.razem AT siol.net>
1827 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
1828 made the linker quiet
1830 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
1832 * src/pic16/gen.c (genPcall): fixed bug #1443644
1833 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1834 which dumps before the function entry point a data byte which represents
1835 the number of the local variables used by the specified function, added
1836 'xinst' for initial support for Extended Instruction Support,
1837 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1838 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1839 port->fun_prefix anymore (may change later),

1841 _main (this should take care the --main-return command line option in
1843 (genOr): removed some legacy pic-port instructions,
1844 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1845 performing operations with SFR's causes data to be written more than

1852 --extended or -y for Extended Instruction Support,
1853 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1854 (deassignLRs): *** perhaps the most important change, old 'for' code
1855 (commented out for reference), didn't account for some registers which
1856 were left marked 'not free' after a pointer operation. The change
1857 reduces register usage a lot in some cases

4132 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
4133 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
4134 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
4135 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
4136 always available in leading double underscore form. The C99 support is

4215 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
4217 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
4219 * device/lib/printf_large.c: removed inline assembly for portability and
4220 readability. Use printf_fast if speed or size are more important.
4221 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4222 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4224 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4226 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4227 prevent compiler warning
4229 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4231 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4232 moved to level 0 and declared as static. Also they are explicit
4233 placed in access bank. This was necessery because some times they
4234 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4235 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4236 optimizations. Currently only compare to unsigned char is implemented,
4237 * src/pic16/gen.c: added fReturnIdx array,
4238 * (struct resolvedIfx) is moved to gen.h and made public,
4239 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4240 * (aopForSym): added an optimization to directly store in stack of
4241 the operand of a SEND iCode,
4242 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4243 but as registers instead (AOP_REG) using the fReturnIdx array,
4244 * (pic16_freeAsmop): remove the freed register from the
4245 _G.sregsAlloc field,
4246 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4247 a compare of 'WREG',
4248 * (pic16_popGetTempRegCond): changed function prototype, now
4249 function takes also a bitVector argument v which holds the current
4250 set of registers that are allocated for stack access by aopForSym,
4251 registers allocated in aopForSym for accessing stack symbols are not
4252 any more part of the functions usedRegs field,
4253 * (genCall): some times aopOp is called for a stack variable to be
4254 send, aopForSym might perform the push, if this is true make sure
4255 that genCall doesn't push the variable twice by testing _G.resDirect,
4256 * (genFunction): changed testing for unspecified interrupt number
4257 from 256 to INTNO_UNSPEC,
4258 * modified selection scheme of frame pointer generation. Previously
4259 if function did use local registers a frame pointer was generated,
4260 now a frame pointer is generated only if function has arguments
4261 (that need PLUSW2 register access), or has stack arguments, or the
4262 compiler is not instructed to omit the frame pointer,
4263 * (genEndFunction): before restoring local registers that were saved
4264 in the function preamble, also restore the registers that *might*
4265 have been allocated for stack access,
4266 * (genRet): removed some old comments,
4267 * (genCmp, the active (RN's) version): added a call to the
4268 pic16_genCmp_special function to perform the compare with a more
4269 robust and optimized way,
4270 * (genInline): a feature has been added in inline code generation,
4271 which allows a wildcard variable substitution when writing inline
4272 assembly. Code is incomplete and experimental therefore undocumented,
4273 * (genCast): changed order of aopOp for result and right to allow
4274 aopForSym to directly load the result if possible,
4275 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4276 perform an optimized compare on some selected special occasions,
4277 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4278 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4279 generate an IVT any more,
4280 * src/pic16/main.c (pic16_optionsTable): added command line option
4282 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4283 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4285 * src/pic16/NOTES: Raphael Neider added in list of active developers
4286 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4287 jumptable_end to prevent bug #,
4288 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4289 inCond and outCond fields,
4290 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4291 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4292 turn off register spilling,
4293 * (packRegsForOneUse): synced with other ports' versions although it
4294 is not used currently,
4295 * (pic16_packRegisters): added an optimization while reading
4296 structure bitfields, some registers may be saved (malloc code is
4297 decreased by 80 bytes)
4299 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4301 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4302 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4303 this can be optimized more?
4305 2005-03-10 Raphael Neider <rneider AT web.de>
4307 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4308 genNearPointerGet): (hopefully) fixed access to bitfields via
4309 pointers (p->bitN = x; and x = p->bitN; failed)
4311 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
4313 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"
4315 2005-03-09 Raphael Neider <rneider AT web.de>

4943 Adding support for replacing ljmps with sjmps in jumptables
4944 generated for switch statements. For now you need to set the
4945 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4946 Now 4 algorithms for mcs51 jumptable generation are used:
4947 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4948 addresses loaded pc-relative for up to 112 cases and stack-pushing
4949 target addresses loaded with offset from dptr for up to 256 cases.

4979 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4981 * added libc directory. The current version of LibC contains string
4982 functions, ctype functions and macros and some functions of the
4983 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4984 be extensively tested in the future. Standard disclaimer here.
4985 Library is not automatically build yet. But one can build it by
4986 invoking 'make' inside the libc directory.

4997 * (pic16_storeForReturn): optimized return of 0,
4998 * (genCmp): experimental code for new genCmp which uses PIC18's
4999 special compare&skip instructions. Initial tests fail some times
5000 with variables grater than 1 byte in size, so new code is disabled,
5001 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5003 * (genCast): began a fix to optimize the casting of a bit to another
5004 bit, now assigning a bitfield to another bitfield will fail, sorry,

5013 and 1 for banking instruction,
5014 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
5015 caused stop processing pCodes after a inline assembly block,
5016 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
5017 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
5018 registers when it shouldn't,
5019 * src/pic16/ralloc.c (allocReg): add preliminary support for
5020 supporting a limited set of temporary registers,
5022 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5028 (genFunction): optimize RECEIVE iCodes in reentrant functions
5030 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5032 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

8030 loaded with the linker search paths (-L arguments) and the libraries
8031 to be linked with the current source (-l arguments). Changes
8032 currently will affect only the pic16 port.
8033 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8034 include path the port specific paths and port specific libraries,
8035 * gplink command now contains the $3 argument,
8036 * src/pic16/device.h,
8037 * src/pic16/device.c,: structure PIC_device is made public and

8053 Documenting changes from previous commits.
8054 * configure.in (version 1.56),
8055 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8056 when generating output files to configure the pic16 library,
8057 but now I've commented it out, since gputils aren't installed in the
8058 SF compile farm, so library won't compile
8060 * device/lib/Makefile.in (version 1.56): initially I've added in
8061 target 'all' the prerequestive 'model-pic16' so it compiled the
8062 pic16 library, but now I've commented it out for the same reasons
8064 * added targets 'model-pic16' and 'objects-pic16' to compile the
8066 * added target 'port-specific-objects-pic16' to handle the
8067 generated libraries and copy them into the build/ directory
8068 * added target 'clean-intermediate-pic16' to clean intermediate
8069 files into pic16 directory
8070 * in target 'installdirs' added line to create directory pic16 in

8074 added lines to copy all header files to installation path,
8075 * in target 'installdirs' added line create directory for pic16
8076 headers in the installation path

8324 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8326 A python script to validate compiler diagnostic messages. It can be
8327 used to verify that sdcc complains about bad c source code and
8328 gives a good location of the error.
8329 * support/valdiag/Makefile,
8330 * support/valdiag/valdiag.py,
8331 * support/valdiag/tests/*
8333 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8335 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
8336 * src/SDCCsymt.c (newEnumType),
8338 * support/Util/SDCCerr.c,
8339 * support/Util/SDCCerr.h: fixed bug #871258 and some other unreported
8341 * support/regression/tests/enum.c: added test for enum values that
8342 require at least 2 bytes of storage.
8344 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8346 * src/common.h: added ifndef/define/endif macros
8347 around the header file.
8348 Bug reported from Jesus Calvino-Fraga
8350 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8352 * sdcc.spec: updated
8353 * device/include/Makefile.in: don't install CVS directories
8354 * device/lib/Makefile.in: added removal of CVS directories after install
8355 * doc/Makefile: fixed install, added local_icons
8356 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8357 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8358 * src/ds390/gen.c (genRightShift): fixed bug #870788
8359 * src/SDCCast.c (decorateType): fixed bug #870781
8361 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8363 PIC16 port related changes:
8364 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8365 added variable stackPos,
8367 * gen.c: genCall, assignResultValue: added support for
8368 pushing/retrieving function parameters to/from stack,
8369 genFunction,genEndFunction: setup stack frame for the
8371 genAddrOf: will be changed according to bug 863624
8373 * added files genutils.c and genutils.h which contain gen*
8374 debugged and optimised functions extracted from gen.c
8376 * glue.c: added variable 'externs' which holds extern symbols,
8377 pic16emitRegularMap: is modified to properly handle relocatable
8378 symbols under the new scheme,
8379 pic16createInterruptVect: is modified
8380 pic16printPublics: is modified to emit 'global' assembler directives,
8381 added pic16_printExterns to print extern symbols,
8382 pic16glue: initializes stack/frame pointer in the beginning of
8383 the assembly output. Temporary hack, will be corrected later,
8384 because gplink yet does not support stack and SDCC does not
8385 yet support a type of crt0.o object to create the final binary.
8387 * Removed many lines that contain 8051 legacy code.
8388 * The code is finally placed under a 'code' directive.
8389 * Added port specific options.
8391 * _process_pragma: simplified since now we do not need *special*
8392 include file to define SFR registers. But a separate header
8393 will be needed. This will be developed later.
8394 * _pic16_parseOptions: added, parses port specific options:
8395 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8396 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8397 --preplace-udata-with=
8399 * _pic16_setDefaultOptions: modified to initialize section names,
8400 but hack is temporarly out of order since it needs improvement.
8401 * _pic16_genAssemblerPreamble: configuration words are emitted by
8402 their address instead of their name. This part is incomplete and
8403 supports only the 18Fxx2 devices. Other devices will emit an error
8404 during assembly since they do not contain the same set of config
8406 * _pic16_genIVT: is modified,
8408 * pcode.c: added definitions for some hardware registers that are needed
8410 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8411 All PCI entries are updated. Now LFSR is supported.
8412 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8413 * added pic16_newpCodeOpLit2 to support instructions with
8414 two literal arguments
8415 * pic16_pCode2str: corrected code that emits assembler instructions
8416 with two literal operands and those that have an access bit modifier
8417 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8418 this fixes a bug which caused some labels to be lost, when an
8419 assembler directive was added, i.e. banksel,
8420 * pic16_FixRegisterBanking: improved logic that causes the insertion
8422 * InlineFunction: functions that are called once, are not any more
8423 inlined. This can be a port option in the future,
8425 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8427 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8428 hold the corresponding uninitialized symbols,
8429 * pic16_allocProcessorRegister: registers have explicit marked the
8431 * pic16_allocInternalRegister: registers are explicit marked as
8433 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8434 processing list, so bit registers were lost,
8437 * ralloc.h: added field 'accessBank' and original symbol operand
8438 in register definition,
8439 * removed the field isMapped from register definition,
8441 ** Several functions have been removed from various sources:
8442 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8443 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8444 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8445 pic16_assignRelocatableRegisters
8447 ** others have been introduced:
8448 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8449 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8451 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8453 * support/scripts/inc2h.pl: changed definition of BIT_AT
8454 to emit 'sbit at' instead of 'bit at'. This was a request.
8456 PIC16 port related preliminary changes:
8457 * gen.c: prefixed function popRegFromString with
8458 pic16_ and all references to it corrected
8459 * pcode.c: all pic16_pc_* hardware registers prefixed
8460 with underscore (_),
8461 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8462 * ralloc.c: newReg(): when register is REG_SFR then
8463 set address to rIdx,
8464 pic16_allocProcessorRegister(): marks register wasUsed=0
8465 pic16_writeUsedRegs(): added a call to assign processor
8466 registers via pic16_assignFixedRegisters
8468 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8470 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8471 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8472 variables in unused register banks. Also the SSEG is placed
8473 wherever there is enough space for it, and IDATA can be anywhere
8474 in internal RAM. For now compile using -Wl-Y[stack_size].
8475 The mem file is different for this option as well, since it
8476 makes no sense of talking about DSEG lenght.
8478 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8480 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8481 in certain cases, e.g. when ROM assignment, patch provided
8482 from Albert den Haan.
8484 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8627 * src/mcs51/peephole.def,
8628 * src/ds390/peephole.def: using the atomic test and clear instruction jbc

8640 multiply defined with mismatching "at" address.
8642 2003-12-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8644 * src/ds390/main.c (PORT tininative_port): fixed bug #858416

8723 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8725 * src/SDCCast.c (decorateType): disabled a transformation I added in
8726 revision 1.188 (access to fields of a structure at an absolute address);
8727 it breaks with bitfields, extern declarations, and gcse analysis.
8728 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
8729 could be assigned through a pointer, so don't complain.
8730 * src/SDCCast.c (astErrors),
8732 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

9370 support for standard C idiom of memory mapped variables; for
9371 example, *((xdata int*)0x1234) = 1 is now internally equivalent
9372 to xdata int at 0x1234 tempvar = 1.
9373 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
9374 provided by Akiya ISHIDA

9390 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9392 Fixed bug #621531 (const & volatile confusion in the type chain).
9393 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
9394 refer to the const or volatile state of the pointer itself.

9485 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
9486 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
9487 fetching of the pointer
9488 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
9489 copied from genNearPointerSet()
9490 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
9491 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
9492 If they pop r0/r1 they must be called in the opposite order than aopOp().
9493 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
9494 (resp. --stack-auto), prepared for --xstack

9505 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
9507 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9508 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9509 type for bits was changed. It resulted in bit variables becoming
9510 global, which is not permitted in PIC 14 assembly output.
9512 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9514 * doc/sdccman.lyx: various additions and updates. Rearranged sections

9527 A few small changes that speed up the peephole optimizer.
9531 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9533 Try to make the peephole optimizer smarter by maintaining
9534 an association between the assembly source code and the
9535 iCodes that originated them. Put this information to use
9536 with a new peephole rule condition "notVolatile" so that
9537 the rules can be aggressive yet still safe.
9542 * src/mcs51/peeph.def
9544 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9548 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9549 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9550 if the left or right operand symbols have the accuse flag set.
9552 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9554 Changed the type of the result of the ! (NOT) operator to char;
9555 previously it returned the same type as the source. This allows
9556 us to eliminate all the genFloatNot functions (all of its target
9557 implementations were very buggy) since !float can use the same

9569 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9570 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9571 during interrupts. Ensure WSAVE is located at a shared bank address.
9572 2. Fixed page selection in some places
9573 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9574 the registers name strings.
9575 4. Fixed "signed / unsigned compare" compiler warnings.
9576 5. The PIC port manages its own allocation of the general purpose
9577 registers, but makes no attempt to reuse them. As a result when
9578 compiling it soon runs out of general purpose registers. Some
9579 additional code was added to the files pcode.c and device.c to walk
9580 through the function call tree and rename the registers so that they
9590 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9591 genPlus() & genMinus() when the result is the same as left or right

9597 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9599 Made bitfield a distinct type from bit so that bitfields
9600 convert as per ANSI C and bits retain their traditional
9601 boolean style behaviour. Implemented bitfield support in
9609 * src/ds390/gen.c: bit v bitfield split
9610 * src/z80/gen.c: New support for bitfields
9611 * support/regression/tests/bitfields.c: reenabled z80,
9614 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9616 Rules 246.x, 247.x relate to bitfields, the others speed up
9617 access to xdata mapped I/O devices.
9619 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9621 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9623 Cleaned up genPackBits and genUnpackBits and added two helper
9624 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9625 for literal assignments in genPackBits (thanks to Frieder for
9631 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9633 Fixed bug #748310 (pointer to function type mishandled when the
9634 function name is omitted). Also fixed a SIGSEGV when a function
9635 attribute (reentrant, etc) is used on a non-function or on a
9636 function but misplaced before the parameter list.
9638 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9640 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
9641 * support/Util/SDCCerr.h,
9642 * support/Util/SDCCerr.c: Added func attr misuse error msg

9663 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9665 Made the constant following the "interrupt" keyword optional. If
9666 omitted, the function will not automatically be given an entry
9667 in the interrupt vector table (similar to #pragma NOIV, but
9668 less syntacticly kludgy). The interrupt number is also now
9669 range checked. Also fixed a bug in the high order bit example

9683 * src/SDCCicode.c (operandOperation): rewritten some ops
9684 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
9685 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9687 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9688 be re-activated by defining REDUCE_LITERALS)
9689 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
9690 unsigned, but are signed by default
9691 * src/SDCCval.c (constVal): rearranged
9692 * src/SDCCval.c (valMod): preliminary fix
9693 * src/SDCCval.c (valCastLiteral): use TYPE_* types

10200 messages from optionsTable when a port is not configured, added
10201 support for the PIc16 port in the ports table, when executing
10202 the compiler with no port specified on command line, a default
10203 port is selected with the new macro DEFAULT_PORT which is
10204 defined in port.h, in setDefaultOptions() linkOptions is removed
10205 from initialization assignment, since now it is a set,
10206 parseCmdLine uses setParseWithComma for linkOptions, in
10207 linkEdit() linkOptions are accessed with new function indexSet()
10208 which returns the i'th item of a set variable. See SDCCset.c, in
10209 linkEdit() when calling buildCmdLine(), added linkOptions as
10210 last argument. Now users can pass arguments to gplink via the
10211 -Wl option, main() uses pic16glue() to glue up pic16 programs

10225 gpasm complaining and test the linkage with gplink, _linkCmd and
10226 _asmCmd changed to be more gplink and gpasm friendly
10227 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10228 produced an error when parsed, peep rule 12 is added to utilize
10229 movff, but it is commented out since the pCode does not support
10230 yet a command with 2 address arguments

11209 2003-01-12 Bernhard Held <bernhard AT bernhardheld.de>
11211 * src/SDCCmain.c (main): port->finaliseOptions() moved for z80 linking
11212 * src/SDCCutil.c (join): ugly bug: missing '\0'

11256 2003-01-07 Bernhard Held <bernhard AT bernhardheld.de>
11257 * as/mcs51/lkmem.c: added several l-modifiers to printf to remove warnings
11258 * as/mcs51/lkaomf51.c: #include <ctype.h> to remove warnings
11259 * src/pic/main.c (_hasNativeMulFor): outcommented unused variables to remove warnings

11267 2003-01-06 <johan AT balder>
11269 * src/SDCCicode.c: fixed array add
11271 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
11272 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
11273 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
11275 2003-01-04 <johan AT balder>

11279 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11280 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
11282 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
11283 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
11284 * support/regression/tests/bug-524697.c: fit mem usage into 8032
11286 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
11287 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
11289 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
11290 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
11292 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
11293 * src/mcs51/main.c: removed {bindir}{sep} from aslink
11295 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11297 * in /sdcc/as/mcs51/ changed these files in order to create an
11298 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11299 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11300 following files to include the previous two files: aslink.dsp,
11301 Makefile.aslink, Makefile.bcc, and Makefile.in.
11303 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11304 .adb instead of .cdb
11306 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11308 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11309 value from option --iram-size.
11311 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11313 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11316 2002-09-18 <wiml AT hhhh.org>
11318 * SDCClrange.h: exposed setFromRange() and setToRange()
11319 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11320 packRegsForAccUse() (bug 542397)
11321 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11322 multiple times and emitting the fetch operations more than once
11323 added aopGetUsesAcc() function to allow binary operators to
11324 fetch their operands in the correct order; made genMinus() emit
11325 compact code for X = LITERAL - Y
11327 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11328 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11329 sprintf() in line 1267.
11331 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11332 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11335 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11336 Changes to aslink (All the changes are marked with 'JCF'):
11338 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11341 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11342 area BSEG. Also moves, if possible, the DATA area down into the internal
11343 ram so more space is available.
11345 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11348 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11349 not bytes. Function summary() which creates a memory usage summary
11350 file with extension .mem. Reports of overlaping stack and small stack
11351 size. If the space for the stack is less than 16 bytes aslink trows a
11354 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11355 the 8051. Option 'y' for memory summary output file.
11357 Changes to sdcc (All the changes are marked with 'JCF'):
11359 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11361 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11362 overlaying area for it (uses RegBankUsed[4]).
11364 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11365 bank zero as used by default. By default aslink locates the stack
11366 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11367 the creation of the .mem file. Delegates the allocation of data area
11368 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11369 the begining of the stack area to aslink.
11371 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11372 glue() in SDCCglue.c creates an area for it.
11374 2002-09-03 Borut Razem <borut.razem AT siol.net>
11375 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11376 sdcc/src/pic/glue.c:
11377 introduced atexit() handler for teporay files removal in case of
11378 errors, assertions, ...
11380 2002-08-29 Borut Razem <borut.razem AT siol.net>
11381 * sdcc/support/cpp2/auto-host_vc_in.h:
11382 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11383 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11384 Maybe there is a similar problem with BORLANDC? It should be checked!
11386 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11387 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11388 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11389 was not executed, and the compiler (cl) launched a warning:
11390 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11392 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11393 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11395 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11396 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11398 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11399 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11400 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11401 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11402 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11403 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11404 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11405 - added Release configuration in VS projects
11406 - review of compiler an linker options
11407 - VC .exe files are generated in bin_vc directory, not to interfere
11408 with binaries generated from other projects (cygwin, mingw, bcc ...)
11410 * sdcc/src/yacc.dsp: added
11412 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11413 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11414 and insert the version number definitions from .version
11416 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11418 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11419 added - genarate auto-host.h using auto-host_vc_in.h as template
11422 removed from CVS, generated automatically
11424 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11425 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11427 2002-08-11 Borut Razem <borut.razem AT siol.net>
11428 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11430 2002-08-10 Borut Razem <borut.razem AT siol.net>
11431 * src/SDCCmain.c (main):
11432 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11433 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11434 The consequence was that some temporary files were not removed.
11437 unification of code in functions tempfilename() and tempfile():
11438 function tempnam() is defined in Visual Studio 6.0 and .NET
11440 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11442 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11443 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11444 - removed compiler command line option /WX: Treats all warnings as errors
11445 - update a list of source files, included into the project
11447 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11448 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11449 changed project type to Generic Project so that can be correcly converted to VS.NET project
11451 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11453 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11455 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11457 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11458 added return 0 statements after assert() to make compiler happy
11460 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11461 added newline in the def file to keep MSC compiler satisfied
11463 * sdcc/src/z80/gen.c:
11464 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11465 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11466 - solved MSC error in function aopDump()
11468 * sdcc_vc.h: define PREFIX as "\\sdcc"
11470 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
11471 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
11473 2002-06-22 Scott Dattalo <scott AT dattalo.com>
11474 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
11475 - Rewrote the register banking algorithm.
11476 - Added pCode live-range analysis to registers (for now, only non-used and
11477 singly-used registers optimized away)
11479 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
11481 * 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.

11498 * device/lib/z80/printf.c (sprintf): Added.
11500 * src/z80/ralloc.c (packRegisters): Disabled pack HL use for GB as it's broken.
11502 * src/z80/peeph.def: Added transpose redundent load rule.
11504 * src/z80/main.c: Added force callee saves for jaune.
11506 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
11508 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
11510 2002-03-28 Johan Knol <johan AT balder>
11512 * src/SDCCval.c: fixed bug #532436
11514 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11516 Added "char *Processor" field to the port structure.
11519 Added -p option. Allows port dependent processor to be specified.
11522 Initialized the new field char *Processor field to NULL in all ports
11525 Compiler generated registers for interrupt context saving
11526 were not getting allocated.
11528 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
11531 Fixed left shift. Will promote the left side of a left shift
11532 if a) left shifting more than size of operand or b) when assigned
11533 to something size > size of left side
11535 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11537 tons of changes. Register allocation has been
11538 rewritten. Added customization for the various PICs. Flow
11539 analysis is restructured. ...
11541 * src/pic/device.h:
11544 * src/pic/device.c:
11545 Added. device.c is a PIC port hack to accomodate variations
11548 2002-03-13 Michael Hope <michaelh AT vroom>
11550 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
11552 2002-03-04 johanknol <johanknol AT manik>
11554 * /src/SDCCval.c: fixed
11556 const unsigned char arr[][2] = { { 0, 1 } };
11557 t18.c:1: error: Initializer element is not constant

11615 * src/z80/ralloc.c (packRegsForIYUse): Fixed fp bug where four byte operands were packed into IY.
11617 2002-03-01 <johan AT FRIJA>
11619 * src/SDCCglue.c (printIvalPtr): fixed bug #524211
11621 * src/SDCCast.c (decorateType): fixed bug #524209

11643 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
11645 * sdcc/src/SDCCloop.c:
11646 Previous fix was not good. basic blocks that have "break" or "return" are
11647 not really partof a loop , but live ranges used in these blocks should
11648 be live thru the entire loop, so set partOfLoop but don't add them to
11651 2002-02-21 <johan AT FRIJA>
11653 * src/SDCCcse.c: fixed bug #514308
