1553 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1555 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1556 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1558 One basic decision: e.g. src/clean.mk includes further files. In order
1559 to make this work there are two solutions:
1560 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1561 run configure on them. This way they can use
1562 'include $(srcdir)/port-clean.mk'
1563 - always include clean.mk by the Makefile at the same level. To avoid
1564 that `make clean` tries to include and build Makefile.dep the
1565 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1566 implemented, because now even `make uninstall` doesn't create
1567 Makefile.in. clean.mk could be eliminated by pasting it in
1570 * debugger/mcs51/Makefile.in: build own objects from library sources
1571 (SLIB, SDCC) in current directory
1573 * configure, configure.in: renamed --disable-device-lib-build in
1574 --disable-device-lib; added --enable-doc, the required tools are
1575 searched by configure; added result message; the toolchain for the
1576 belonging ports are now only built, if the port is enabled.
1578 * support/regression/*: all output is written in directory gen, because
1579 the fwk and ports directories don't livet in the build tree using vpath
1581 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1582 --disable-device-lib, added --enable-doc, added section VPATH
1584 * sim/ucsim/configure.in,
1585 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1586 z80 are enabled by default
1588 2006-04-24 Raphael Neider <rneider AT web.de>
1590 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1591 to config word, "pic14_"-prefixed some extern functions
1592 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1593 config word has been found
1594 * src/pic/device.h: added prototypes
1595 * src/pic/pcode.c: added "pic14_"-prefix where needed
1596 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
1598 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

1845 2006-03-29 Maarten Brock <sourceforge.brock AT dse.nl>
1847 * src/SDCCpeeph.c (operandsLiteral): new, added,

1859 implemented patch 1120823 Thanks to Willy De la Court (normal
1860 interrupts need an interrupt number now if they are made critical),
1861 and enabled nesting of critical functions though not for gbz80
1862 (genCritical, genEndCritical): added functions
1863 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1864 * src/z80/mappings.i: added "ei" to all mappings

1869 submitted by the Debian SDCC maintainer Aurelien Jarno:
1870 "Credits goes to Martin Michlmayr, who rebuilt the whole Debian

1873 2006-03-16 Raphael Neider <rneider AT web.de>
1875 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
1876 the left operand is shorter than the result (c* = lit-c* + int),
1878 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1881 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1883 * src/.version: increased version number to 2.5.5
1884 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1885 linking is done manually in pic16 port's _linkEdit,
1886 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1887 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1888 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1889 allocate asmop as AOP_ACC,
1890 (aopForRemat): added parameter 'bool result' in function declaration,
1891 (pic16_aopGet): return AOP_ACC when accessing WREG,
1892 (pic16_popGetTempReg): minor modification,
1893 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
1894 'pic16_allocWithIdx',

1901 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
1903 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1904 call to allocReg, not by manually allocating a new one,
1905 (pic16_assignRegisters): now before going through the register
1906 allocating functions mark all registers as free. This eliminates some
1907 side effects resulting from peephole parser done earlier in the backbone
1909 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

1931 (aopForSym, aopOp): increment asmop.allocated if reused,
1932 (freeAsmop): decrement asmop.allocated and check for zero instead of
1934 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
1935 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,
1936 genCmpLt, genAndOp, genOrOp, genAnd, genOr, genXor, genRRC, genRLC,

1967 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1968 which dumps before the function entry point a data byte which represents
1969 the number of the local variables used by the specified function, added
1970 'xinst' for initial support for Extended Instruction Support,
1971 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1972 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1973 port->fun_prefix anymore (may change later),
1974 (genFunction, genEndFunction): do not store/restore local registers for
1975 _main (this should take care the --main-return command line option in
1977 (genOr): removed some legacy pic-port instructions,
1978 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1979 performing operations with SFR's causes data to be written more than
1980 once to each SFR. Perhaps SFRs should be handled in special cases...
1981 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1983 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1984 into account for stack starting position,

1986 --extended or -y for Extended Instruction Support,
1987 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1988 (deassignLRs): *** perhaps the most important change, old 'for' code
1989 (commented out for reference), didn't account for some registers which
1990 were left marked 'not free' after a pointer operation. The change
1991 reduces register usage a lot in some cases

4317 * src/SDCCBBlock.h (struct ebbIndex): new struct that keeps two copies
4318 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
4319 immedDom() returning wrong block; probably fixes bug #1160833)
4321 2005-03-20 Borut Razem <borut.razem AT siol.net>
4323 * support/scripts/inc2h.pl: WIN32 port
4325 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
4327 * device/lib/makefile.in: added abs.c and labs.c
4329 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
4331 * device/include/stdint.h: added
4332 * device/lib/abs.c: added
4333 * device/lib/labs.c: added
4334 * device/include/stdlib.h: added abs() and labs() prototypes
4335 * device/lib/libsdcc.lib: added abs and labs
4336 * device/include/float.h,
4337 * device/lib/_fsmul.c,
4338 * device/lib/printf_fast.c,
4339 * device/lib/printf_tiny.c: updated comments
4341 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4343 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
4346 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4348 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
4349 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
4351 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
4353 * device/lib/printf_large.c: removed inline assembly for portability and
4354 readability. Use printf_fast if speed or size are more important.
4355 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4356 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4358 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4360 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4361 prevent compiler warning
4363 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4365 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4366 moved to level 0 and declared as static. Also they are explicit
4367 placed in access bank. This was necessery because some times they
4368 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4369 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4370 optimizations. Currently only compare to unsigned char is implemented,
4371 * src/pic16/gen.c: added fReturnIdx array,
4372 * (struct resolvedIfx) is moved to gen.h and made public,
4373 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4374 * (aopForSym): added an optimization to directly store in stack of
4375 the operand of a SEND iCode,
4376 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4377 but as registers instead (AOP_REG) using the fReturnIdx array,
4378 * (pic16_freeAsmop): remove the freed register from the
4379 _G.sregsAlloc field,
4380 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4381 a compare of 'WREG',
4382 * (pic16_popGetTempRegCond): changed function prototype, now
4383 function takes also a bitVector argument v which holds the current
4384 set of registers that are allocated for stack access by aopForSym,
4385 registers allocated in aopForSym for accessing stack symbols are not
4386 any more part of the functions usedRegs field,
4387 * (genCall): some times aopOp is called for a stack variable to be
4388 send, aopForSym might perform the push, if this is true make sure
4389 that genCall doesn't push the variable twice by testing _G.resDirect,
4390 * (genFunction): changed testing for unspecified interrupt number
4391 from 256 to INTNO_UNSPEC,
4392 * modified selection scheme of frame pointer generation. Previously
4393 if function did use local registers a frame pointer was generated,
4394 now a frame pointer is generated only if function has arguments
4395 (that need PLUSW2 register access), or has stack arguments, or the
4396 compiler is not instructed to omit the frame pointer,
4397 * (genEndFunction): before restoring local registers that were saved
4398 in the function preamble, also restore the registers that *might*
4399 have been allocated for stack access,
4400 * (genRet): removed some old comments,
4401 * (genCmp, the active (RN's) version): added a call to the
4402 pic16_genCmp_special function to perform the compare with a more
4403 robust and optimized way,
4404 * (genInline): a feature has been added in inline code generation,
4405 which allows a wildcard variable substitution when writing inline
4406 assembly. Code is incomplete and experimental therefore undocumented,
4407 * (genCast): changed order of aopOp for result and right to allow
4408 aopForSym to directly load the result if possible,
4409 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4410 perform an optimized compare on some selected special occasions,
4411 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4412 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4413 generate an IVT any more,
4414 * src/pic16/main.c (pic16_optionsTable): added command line option
4416 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4417 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4419 * src/pic16/NOTES: Raphael Neider added in list of active developers
4420 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4421 jumptable_end to prevent bug #,
4422 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4423 inCond and outCond fields,
4424 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4425 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4426 turn off register spilling,
4427 * (packRegsForOneUse): synced with other ports' versions although it
4428 is not used currently,
4429 * (pic16_packRegisters): added an optimization while reading
4430 structure bitfields, some registers may be saved (malloc code is
4431 decreased by 80 bytes)
4433 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4435 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4436 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4437 this can be optimized more?
4439 2005-03-10 Raphael Neider <rneider AT web.de>
4441 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4442 genNearPointerGet): (hopefully) fixed access to bitfields via
4443 pointers (p->bitN = x; and x = p->bitN; failed)
4445 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

4633 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
4634 this might fix SIGSEGVs on MinGW...

5078 generated for switch statements. For now you need to set the
5079 environment variable SDCC_SJMP_JUMPTABLE to enable this.
5080 Now 4 algorithms for mcs51 jumptable generation are used:
5081 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

5113 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
5115 * added libc directory. The current version of LibC contains string
5116 functions, ctype functions and macros and some functions of the
5117 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
5118 be extensively tested in the future. Standard disclaimer here.
5119 Library is not automatically build yet. But one can build it by
5120 invoking 'make' inside the libc directory.

5131 * (pic16_storeForReturn): optimized return of 0,
5132 * (genCmp): experimental code for new genCmp which uses PIC18's
5133 special compare&skip instructions. Initial tests fail some times
5134 with variables grater than 1 byte in size, so new code is disabled,
5135 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5137 * (genCast): began a fix to optimize the casting of a bit to another
5138 bit, now assigning a bitfield to another bitfield will fail, sorry,

5147 and 1 for banking instruction,
5148 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
5149 caused stop processing pCodes after a inline assembly block,

5152 registers when it shouldn't,
5153 * src/pic16/ralloc.c (allocReg): add preliminary support for
5154 supporting a limited set of temporary registers,
5156 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5162 (genFunction): optimize RECEIVE iCodes in reentrant functions
5164 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5180 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
5182 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

8116 code / RAM are in the same page / bank. This means the linker can
8117 safely allocate code/RAM of separate ASM files to different pages/banks.
8118 * doc/sdccman.lyx: added Slade's tips

8161 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
8163 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
8164 loaded with the linker search paths (-L arguments) and the libraries
8165 to be linked with the current source (-l arguments). Changes
8166 currently will affect only the pic16 port.
8167 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8168 include path the port specific paths and port specific libraries,
8169 * gplink command now contains the $3 argument,
8170 * src/pic16/device.h,
8171 * src/pic16/device.c,: structure PIC_device is made public and
8172 renamed to PIC16_device, the same for variable Pics which is renamed

8187 Documenting changes from previous commits.
8188 * configure.in (version 1.56),
8189 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8190 when generating output files to configure the pic16 library,
8191 but now I've commented it out, since gputils aren't installed in the
8192 SF compile farm, so library won't compile
8194 * device/lib/Makefile.in (version 1.56): initially I've added in
8195 target 'all' the prerequestive 'model-pic16' so it compiled the
8196 pic16 library, but now I've commented it out for the same reasons
8198 * added targets 'model-pic16' and 'objects-pic16' to compile the
8200 * added target 'port-specific-objects-pic16' to handle the
8201 generated libraries and copy them into the build/ directory
8202 * added target 'clean-intermediate-pic16' to clean intermediate
8203 files into pic16 directory
8204 * in target 'installdirs' added line to create directory pic16 in
8205 the installation path
8207 * device/include/Makefile.in (version 1.11): in target 'install'
8208 added lines to copy all header files to installation path,
8209 * in target 'installdirs' added line create directory for pic16
8210 headers in the installation path

8225 * src/z80/main.c (_parseOptions): fixed the portmode= command line
8226 option so that it actually works. Made it specific to the z80, since
8227 the gbz80 doesn't have these kinds of I/O ports.
8229 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8231 * device/include/z180.h,

8253 Mainly changes to support compilation of the device libraries
8254 * src/pic16/device.c: stack is allocated via symbol and not
8255 via literal number. The symbol is placed in the corresponding
8256 position of the data ram
8257 * (pic16_dump_section): relocatable and absolute uninitialized
8258 data are now emitted in sorted order to reduce section naming,
8259 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
8260 weren't marked as being in the access bank,
8262 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
8264 Added portion of GNU PIC Library under the directory
8265 device/include/pic16 and device/lib/pic16. These files
8266 contain the declarations of SFRs for the PIC18Fxx2 devices.
8267 The directory is initialized via configure from toplevel.
8269 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
8271 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

8278 2004-01-12 Borut Razem <borut.razem AT siol.net>
8280 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,
8281 doc/sdccman.lyx: upper case pragmas are deprecated
8283 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
8285 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results

8296 * doc/sdccman.lyx: Moved and added some sections, small changes
8297 all over. Telling LaTeX to be less strict with word spacing
8298 to better keep the right margin. Changed some notes about
8299 maintainance of the ports in section 3.2.1 - is it OK like this?
8301 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
8303 SDCC source changes:
8304 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

8310 processor registers declared internally by the port are emitted in
8311 the translation as equates,
8312 * src/pic16/gen.c: inline code is passed unprocessed to the

8453 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8455 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
8456 (default behaviour).
8458 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8460 A python script to validate compiler diagnostic messages. It can be
8461 used to verify that sdcc complains about bad c source code and
8462 gives a good location of the error.
8463 * support/valdiag/Makefile,
8464 * support/valdiag/valdiag.py,
8465 * support/valdiag/tests/*

8480 * src/common.h: added ifndef/define/endif macros
8481 around the header file.
8482 Bug reported from Jesus Calvino-Fraga
8484 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8486 * sdcc.spec: updated
8487 * device/include/Makefile.in: don't install CVS directories
8488 * device/lib/Makefile.in: added removal of CVS directories after install
8489 * doc/Makefile: fixed install, added local_icons
8490 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8491 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8492 * src/ds390/gen.c (genRightShift): fixed bug #870788
8493 * src/SDCCast.c (decorateType): fixed bug #870781
8495 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8497 PIC16 port related changes:
8498 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8499 added variable stackPos,
8501 * gen.c: genCall, assignResultValue: added support for
8502 pushing/retrieving function parameters to/from stack,
8503 genFunction,genEndFunction: setup stack frame for the
8505 genAddrOf: will be changed according to bug 863624
8507 * added files genutils.c and genutils.h which contain gen*
8508 debugged and optimised functions extracted from gen.c
8510 * glue.c: added variable 'externs' which holds extern symbols,
8511 pic16emitRegularMap: is modified to properly handle relocatable
8512 symbols under the new scheme,
8513 pic16createInterruptVect: is modified
8514 pic16printPublics: is modified to emit 'global' assembler directives,
8515 added pic16_printExterns to print extern symbols,
8516 pic16glue: initializes stack/frame pointer in the beginning of
8517 the assembly output. Temporary hack, will be corrected later,
8518 because gplink yet does not support stack and SDCC does not
8519 yet support a type of crt0.o object to create the final binary.
8521 * Removed many lines that contain 8051 legacy code.
8522 * The code is finally placed under a 'code' directive.
8523 * Added port specific options.
8525 * _process_pragma: simplified since now we do not need *special*
8526 include file to define SFR registers. But a separate header
8527 will be needed. This will be developed later.
8528 * _pic16_parseOptions: added, parses port specific options:
8529 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8530 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8531 --preplace-udata-with=
8533 * _pic16_setDefaultOptions: modified to initialize section names,
8534 but hack is temporarly out of order since it needs improvement.
8535 * _pic16_genAssemblerPreamble: configuration words are emitted by
8536 their address instead of their name. This part is incomplete and
8537 supports only the 18Fxx2 devices. Other devices will emit an error
8538 during assembly since they do not contain the same set of config
8540 * _pic16_genIVT: is modified,
8542 * pcode.c: added definitions for some hardware registers that are needed
8544 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8545 All PCI entries are updated. Now LFSR is supported.
8546 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8547 * added pic16_newpCodeOpLit2 to support instructions with
8548 two literal arguments
8549 * pic16_pCode2str: corrected code that emits assembler instructions
8550 with two literal operands and those that have an access bit modifier
8551 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8552 this fixes a bug which caused some labels to be lost, when an
8553 assembler directive was added, i.e. banksel,
8554 * pic16_FixRegisterBanking: improved logic that causes the insertion
8556 * InlineFunction: functions that are called once, are not any more
8557 inlined. This can be a port option in the future,
8559 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8561 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8562 hold the corresponding uninitialized symbols,
8563 * pic16_allocProcessorRegister: registers have explicit marked the
8565 * pic16_allocInternalRegister: registers are explicit marked as
8567 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8568 processing list, so bit registers were lost,
8571 * ralloc.h: added field 'accessBank' and original symbol operand
8572 in register definition,
8573 * removed the field isMapped from register definition,
8575 ** Several functions have been removed from various sources:
8576 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8577 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8578 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8579 pic16_assignRelocatableRegisters
8581 ** others have been introduced:
8582 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8583 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8585 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8587 * support/scripts/inc2h.pl: changed definition of BIT_AT
8588 to emit 'sbit at' instead of 'bit at'. This was a request.
8590 PIC16 port related preliminary changes:
8591 * gen.c: prefixed function popRegFromString with
8592 pic16_ and all references to it corrected
8593 * pcode.c: all pic16_pc_* hardware registers prefixed
8594 with underscore (_),
8595 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8596 * ralloc.c: newReg(): when register is REG_SFR then
8597 set address to rIdx,
8598 pic16_allocProcessorRegister(): marks register wasUsed=0
8599 pic16_writeUsedRegs(): added a call to assign processor
8600 registers via pic16_assignFixedRegisters
8602 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8604 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8605 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8606 variables in unused register banks. Also the SSEG is placed
8607 wherever there is enough space for it, and IDATA can be anywhere
8608 in internal RAM. For now compile using -Wl-Y[stack_size].
8609 The mem file is different for this option as well, since it
8610 makes no sense of talking about DSEG lenght.
8612 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8614 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8615 in certain cases, e.g. when ROM assignment, patch provided
8616 from Albert den Haan.
8618 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8759 xdata and data memory on startup. Set the environment variable
8760 SDCC_NOGENRAMCLEAR to disable this.
8761 * src/mcs51/peephole.def,
8762 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
8763 (allows non-interrupt and interrupt code to safely compete for a resource
8764 without the non-interrupt code having to disable interrupts)
8766 2003-12-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8774 multiply defined with mismatching "at" address.
8776 2003-12-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8778 * src/ds390/main.c (PORT tininative_port): fixed bug #858416
8779 * src/SDCCglue.c (printChar, printIvalChar, emitStaticSeg),

9503 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
9504 support for standard C idiom of memory mapped variables; for
9505 example, *((xdata int*)0x1234) = 1 is now internally equivalent
9506 to xdata int at 0x1234 tempvar = 1.
9507 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
9508 provided by Akiya ISHIDA

9524 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9526 Fixed bug #621531 (const & volatile confusion in the type chain).
9527 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively

9607 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
9608 iCode properly now. Use getSize instead of nRegs since a & b
9609 aren't part of the nRegs tally.
9611 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
9613 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

9619 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
9620 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
9621 fetching of the pointer
9622 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
9623 copied from genNearPointerSet()
9624 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
9625 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
9626 If they pop r0/r1 they must be called in the opposite order than aopOp().
9627 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
9628 (resp. --stack-auto), prepared for --xstack

9637 these ports have their own __sdcc_external_start()
9639 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
9641 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9642 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9643 type for bits was changed. It resulted in bit variables becoming
9644 global, which is not permitted in PIC 14 assembly output.
9646 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9648 * doc/sdccman.lyx: various additions and updates. Rearranged sections

9661 A few small changes that speed up the peephole optimizer.
9665 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9667 Try to make the peephole optimizer smarter by maintaining
9668 an association between the assembly source code and the
9669 iCodes that originated them. Put this information to use
9670 with a new peephole rule condition "notVolatile" so that
9671 the rules can be aggressive yet still safe.
9676 * src/mcs51/peeph.def
9678 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9682 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9683 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9684 if the left or right operand symbols have the accuse flag set.
9686 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9688 Changed the type of the result of the ! (NOT) operator to char;
9689 previously it returned the same type as the source. This allows
9690 us to eliminate all the genFloatNot functions (all of its target
9691 implementations were very buggy) since !float can use the same
9694 * src/SDCCicode.c (ast2iCode): ! returns char

9696 * src/ds390/gen.c (genNot, genNotFloat),
9697 * src/z80/gen.c (genNot, genNotFloat),
9698 * src/pic/gen.c (genNot, genNotFloat),

9701 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
9703 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9704 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9705 during interrupts. Ensure WSAVE is located at a shared bank address.
9706 2. Fixed page selection in some places
9707 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9708 the registers name strings.
9709 4. Fixed "signed / unsigned compare" compiler warnings.
9710 5. The PIC port manages its own allocation of the general purpose
9711 registers, but makes no attempt to reuse them. As a result when
9712 compiling it soon runs out of general purpose registers. Some
9713 additional code was added to the files pcode.c and device.c to walk
9714 through the function call tree and rename the registers so that they
9724 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9725 genPlus() & genMinus() when the result is the same as left or right
9727 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9731 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9733 Made bitfield a distinct type from bit so that bitfields
9734 convert as per ANSI C and bits retain their traditional
9735 boolean style behaviour. Implemented bitfield support in
9743 * src/ds390/gen.c: bit v bitfield split
9744 * src/z80/gen.c: New support for bitfields
9745 * support/regression/tests/bitfields.c: reenabled z80,
9748 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9750 Rules 246.x, 247.x relate to bitfields, the others speed up
9751 access to xdata mapped I/O devices.
9753 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9755 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9757 Cleaned up genPackBits and genUnpackBits and added two helper
9758 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9759 for literal assignments in genPackBits (thanks to Frieder for
9765 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9767 Fixed bug #748310 (pointer to function type mishandled when the
9768 function name is omitted). Also fixed a SIGSEGV when a function
9769 attribute (reentrant, etc) is used on a non-function or on a
9770 function but misplaced before the parameter list.
9772 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9774 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
9775 * support/Util/SDCCerr.h,
9776 * support/Util/SDCCerr.c: Added func attr misuse error msg
9778 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
9780 Fixed bug #787649 by anonymous
9781 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
9782 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
9784 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9797 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9799 Made the constant following the "interrupt" keyword optional. If
9800 omitted, the function will not automatically be given an entry
9801 in the interrupt vector table (similar to #pragma NOIV, but
9802 less syntacticly kludgy). The interrupt number is also now
9803 range checked. Also fixed a bug in the high order bit example

10335 support for the PIc16 port in the ports table, when executing
10336 the compiler with no port specified on command line, a default
10337 port is selected with the new macro DEFAULT_PORT which is
10338 defined in port.h, in setDefaultOptions() linkOptions is removed
10339 from initialization assignment, since now it is a set,
10340 parseCmdLine uses setParseWithComma for linkOptions, in

11403 * src/SDCCicode.c: fixed array add
11405 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
11406 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests

11416 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
11417 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

11423 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
11424 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
11426 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
11427 * src/mcs51/main.c: removed {bindir}{sep} from aslink
11429 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11431 * in /sdcc/as/mcs51/ changed these files in order to create an
11432 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11433 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11434 following files to include the previous two files: aslink.dsp,
11435 Makefile.aslink, Makefile.bcc, and Makefile.in.
11437 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11438 .adb instead of .cdb
11440 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11442 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11443 value from option --iram-size.
11445 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11447 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11450 2002-09-18 <wiml AT hhhh.org>
11452 * SDCClrange.h: exposed setFromRange() and setToRange()
11453 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11454 packRegsForAccUse() (bug 542397)
11455 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11456 multiple times and emitting the fetch operations more than once
11457 added aopGetUsesAcc() function to allow binary operators to
11458 fetch their operands in the correct order; made genMinus() emit
11459 compact code for X = LITERAL - Y
11461 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11462 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11463 sprintf() in line 1267.
11465 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11466 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11469 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11470 Changes to aslink (All the changes are marked with 'JCF'):
11472 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11475 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11476 area BSEG. Also moves, if possible, the DATA area down into the internal
11477 ram so more space is available.
11479 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11482 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11483 not bytes. Function summary() which creates a memory usage summary
11484 file with extension .mem. Reports of overlaping stack and small stack
11485 size. If the space for the stack is less than 16 bytes aslink trows a
11488 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11489 the 8051. Option 'y' for memory summary output file.
11491 Changes to sdcc (All the changes are marked with 'JCF'):
11493 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11495 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11496 overlaying area for it (uses RegBankUsed[4]).
11498 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11499 bank zero as used by default. By default aslink locates the stack
11500 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11501 the creation of the .mem file. Delegates the allocation of data area
11502 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11503 the begining of the stack area to aslink.
11505 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11506 glue() in SDCCglue.c creates an area for it.
11508 2002-09-03 Borut Razem <borut.razem AT siol.net>
11509 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11510 sdcc/src/pic/glue.c:
11511 introduced atexit() handler for teporay files removal in case of
11512 errors, assertions, ...
11514 2002-08-29 Borut Razem <borut.razem AT siol.net>
11515 * sdcc/support/cpp2/auto-host_vc_in.h:
11516 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11517 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11518 Maybe there is a similar problem with BORLANDC? It should be checked!
11520 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11521 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11522 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11523 was not executed, and the compiler (cl) launched a warning:
11524 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11526 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11527 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11529 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11530 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11532 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11533 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11534 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11535 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11536 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11537 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11538 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11539 - added Release configuration in VS projects
11540 - review of compiler an linker options
11541 - VC .exe files are generated in bin_vc directory, not to interfere
11542 with binaries generated from other projects (cygwin, mingw, bcc ...)
11544 * sdcc/src/yacc.dsp: added
11546 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11547 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11548 and insert the version number definitions from .version
11550 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11552 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11553 added - genarate auto-host.h using auto-host_vc_in.h as template
11556 removed from CVS, generated automatically
11558 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11559 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11561 2002-08-11 Borut Razem <borut.razem AT siol.net>
11562 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11564 2002-08-10 Borut Razem <borut.razem AT siol.net>
11565 * src/SDCCmain.c (main):
11566 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11567 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11568 The consequence was that some temporary files were not removed.
11571 unification of code in functions tempfilename() and tempfile():
11572 function tempnam() is defined in Visual Studio 6.0 and .NET
11574 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11576 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11577 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11578 - removed compiler command line option /WX: Treats all warnings as errors
11579 - update a list of source files, included into the project
11581 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11582 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11583 changed project type to Generic Project so that can be correcly converted to VS.NET project
11585 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11587 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11589 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11591 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11592 added return 0 statements after assert() to make compiler happy
11594 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11595 added newline in the def file to keep MSC compiler satisfied
11597 * sdcc/src/z80/gen.c:
11598 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11599 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11600 - solved MSC error in function aopDump()
11602 * sdcc_vc.h: define PREFIX as "\\sdcc"
11604 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
11605 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
11607 2002-06-22 Scott Dattalo <scott AT dattalo.com>
