1522 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1524 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1525 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1527 One basic decision: e.g. src/clean.mk includes further files. In order
1528 to make this work there are two solutions:
1529 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1530 run configure on them. This way they can use
1531 'include $(srcdir)/port-clean.mk'
1532 - always include clean.mk by the Makefile at the same level. To avoid
1533 that `make clean` tries to include and build Makefile.dep the
1534 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1535 implemented, because now even `make uninstall` doesn't create
1536 Makefile.in. clean.mk could be eliminated by pasting it in
1539 * debugger/mcs51/Makefile.in: build own objects from library sources
1540 (SLIB, SDCC) in current directory
1542 * configure, configure.in: renamed --disable-device-lib-build in
1543 --disable-device-lib; added --enable-doc, the required tools are
1544 searched by configure; added result message; the toolchain for the
1545 belonging ports are now only built, if the port is enabled.
1547 * support/regression/*: all output is written in directory gen, because
1548 the fwk and ports directories don't livet in the build tree using vpath
1550 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1551 --disable-device-lib, added --enable-doc, added section VPATH
1553 * sim/ucsim/configure.in,
1554 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1555 z80 are enabled by default
1557 2006-04-24 Raphael Neider <rneider AT web.de>
1559 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1560 to config word, "pic14_"-prefixed some extern functions
1561 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1562 config word has been found
1563 * src/pic/device.h: added prototypes
1564 * src/pic/pcode.c: added "pic14_"-prefix where needed
1565 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
1567 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

1799 2006-04-05 Maarten Brock <sourceforge.brock AT dse.nl>
1801 * src/SDCCpeeph.c (initPeepHole): implemented RFE 1460196, when both

1805 2006-04-05 Maarten Brock <sourceforge.brock AT dse.nl>
1807 * src/mcs51/gen.c (genCall): fixed bug 1457608
1809 2006-03-30 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

1814 2006-03-29 Maarten Brock <sourceforge.brock AT dse.nl>
1816 * src/SDCCpeeph.c (operandsLiteral): new, added,

1827 * src/z80/gen.c (genFunction, genEndFunction): fixed bug 1160666,
1828 implemented patch 1120823 Thanks to Willy De la Court (normal
1829 interrupts need an interrupt number now if they are made critical),
1830 and enabled nesting of critical functions though not for gbz80
1831 (genCritical, genEndCritical): added functions
1832 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1833 * src/z80/mappings.i: added "ei" to all mappings
1835 2006-03-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

1838 submitted by the Debian SDCC maintainer Aurelien Jarno:
1839 "Credits goes to Martin Michlmayr, who rebuilt the whole Debian
1840 archive with gcc 4.1 on mips and wrote the patch"
1842 2006-03-16 Raphael Neider <rneider AT web.de>
1844 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
1845 the left operand is shorter than the result (c* = lit-c* + int),
1847 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1850 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1852 * src/.version: increased version number to 2.5.5
1853 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1854 linking is done manually in pic16 port's _linkEdit,
1855 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1856 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1857 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1858 allocate asmop as AOP_ACC,
1859 (aopForRemat): added parameter 'bool result' in function declaration,
1860 (pic16_aopGet): return AOP_ACC when accessing WREG,
1861 (pic16_popGetTempReg): minor modification,
1862 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
1863 'pic16_allocWithIdx',
1864 (genPcall): removed ftype, usage of OP_SYM_TYPE asserted error when
1865 calling function in absolute addresses,
1866 (genAssign): take into account AOP_ACC asmop,
1867 * src/pic16/pcode.c (pic16_newpCodeOpReg): minor modifications,
1868 * src/pic16/pcoderegs.c: some debug functions and lines added,
1869 * src/pic16/ralloc.c (decodeRegType): added but commented out,
1870 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
1872 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1873 call to allocReg, not by manually allocating a new one,
1874 (pic16_assignRegisters): now before going through the register
1875 allocating functions mark all registers as free. This eliminates some
1876 side effects resulting from peephole parser done earlier in the backbone
1878 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
1880 * src/SDCCicode.c (geniCodeLogic),

1899 * src/mcs51/gen.c (newAsmop): set asmop.allocated to 1,
1900 (aopForSym, aopOp): increment asmop.allocated if reused,
1901 (freeAsmop): decrement asmop.allocated and check for zero instead of
1903 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
1904 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,
1905 genCmpLt, genAndOp, genOrOp, genAnd, genOr, genXor, genRRC, genRLC,

1928 2006-03-06 Borut Razem <borut.razem AT siol.net>
1930 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
1931 made the linker quiet
1933 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
1935 * src/pic16/gen.c (genPcall): fixed bug #1443644
1936 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1937 which dumps before the function entry point a data byte which represents
1938 the number of the local variables used by the specified function, added
1939 'xinst' for initial support for Extended Instruction Support,
1940 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1941 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1942 port->fun_prefix anymore (may change later),
1943 (genFunction, genEndFunction): do not store/restore local registers for
1944 _main (this should take care the --main-return command line option in
1946 (genOr): removed some legacy pic-port instructions,
1947 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1948 performing operations with SFR's causes data to be written more than
1949 once to each SFR. Perhaps SFRs should be handled in special cases...
1950 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1952 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1953 into account for stack starting position,
1954 (struct OPTIONS pic16_optionsTable): added command line argument
1955 --extended or -y for Extended Instruction Support,
1956 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1957 (deassignLRs): *** perhaps the most important change, old 'for' code
1958 (commented out for reference), didn't account for some registers which
1959 were left marked 'not free' after a pointer operation. The change
1960 reduces register usage a lot in some cases
1962 2006-03-04 Borut Razem <borut.razem AT siol.net>

4322 * device/lib/printf_large.c: removed inline assembly for portability and
4323 readability. Use printf_fast if speed or size are more important.
4324 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4325 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4327 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4329 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4330 prevent compiler warning
4332 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4334 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4335 moved to level 0 and declared as static. Also they are explicit
4336 placed in access bank. This was necessery because some times they
4337 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4338 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4339 optimizations. Currently only compare to unsigned char is implemented,
4340 * src/pic16/gen.c: added fReturnIdx array,
4341 * (struct resolvedIfx) is moved to gen.h and made public,
4342 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4343 * (aopForSym): added an optimization to directly store in stack of
4344 the operand of a SEND iCode,
4345 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4346 but as registers instead (AOP_REG) using the fReturnIdx array,
4347 * (pic16_freeAsmop): remove the freed register from the
4348 _G.sregsAlloc field,
4349 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4350 a compare of 'WREG',
4351 * (pic16_popGetTempRegCond): changed function prototype, now
4352 function takes also a bitVector argument v which holds the current
4353 set of registers that are allocated for stack access by aopForSym,
4354 registers allocated in aopForSym for accessing stack symbols are not
4355 any more part of the functions usedRegs field,
4356 * (genCall): some times aopOp is called for a stack variable to be
4357 send, aopForSym might perform the push, if this is true make sure
4358 that genCall doesn't push the variable twice by testing _G.resDirect,
4359 * (genFunction): changed testing for unspecified interrupt number
4360 from 256 to INTNO_UNSPEC,
4361 * modified selection scheme of frame pointer generation. Previously
4362 if function did use local registers a frame pointer was generated,
4363 now a frame pointer is generated only if function has arguments
4364 (that need PLUSW2 register access), or has stack arguments, or the
4365 compiler is not instructed to omit the frame pointer,
4366 * (genEndFunction): before restoring local registers that were saved
4367 in the function preamble, also restore the registers that *might*
4368 have been allocated for stack access,
4369 * (genRet): removed some old comments,
4370 * (genCmp, the active (RN's) version): added a call to the
4371 pic16_genCmp_special function to perform the compare with a more
4372 robust and optimized way,
4373 * (genInline): a feature has been added in inline code generation,
4374 which allows a wildcard variable substitution when writing inline
4375 assembly. Code is incomplete and experimental therefore undocumented,
4376 * (genCast): changed order of aopOp for result and right to allow
4377 aopForSym to directly load the result if possible,
4378 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4379 perform an optimized compare on some selected special occasions,
4380 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4381 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4382 generate an IVT any more,
4383 * src/pic16/main.c (pic16_optionsTable): added command line option
4385 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4386 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4388 * src/pic16/NOTES: Raphael Neider added in list of active developers
4389 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4390 jumptable_end to prevent bug #,
4391 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4392 inCond and outCond fields,
4393 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4394 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4395 turn off register spilling,
4396 * (packRegsForOneUse): synced with other ports' versions although it
4397 is not used currently,
4398 * (pic16_packRegisters): added an optimization while reading
4399 structure bitfields, some registers may be saved (malloc code is
4400 decreased by 80 bytes)
4402 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4404 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4405 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4406 this can be optimized more?
4408 2005-03-10 Raphael Neider <rneider AT web.de>
4410 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4411 genNearPointerGet): (hopefully) fixed access to bitfields via
4412 pointers (p->bitN = x; and x = p->bitN; failed)
4414 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
4416 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

4455 2005-02-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4457 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
4458 to keep the correct label reference count when adding/removing references
4459 to labels. A peephole file using this is appended to patch #1144962.

4738 access stack and frame pointers. They are initially assigned to
4739 point at pic16_pc_fsr1[lh] and pic16_pc_fsr2[lh] variables and other
4740 accessing SFRs. Updated all occurences of modification of stack or
4741 frame pointer in gen.c and pcode.c,
4742 * src/pic16/ralloc.c (serialRegAssign): fixed two bugs with
4743 assigning of a literal value to pointers,

5046 Adding support for replacing ljmps with sjmps in jumptables
5047 generated for switch statements. For now you need to set the
5048 environment variable SDCC_SJMP_JUMPTABLE to enable this.
5049 Now 4 algorithms for mcs51 jumptable generation are used:
5050 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
5051 addresses loaded pc-relative for up to 112 cases and stack-pushing
5052 target addresses loaded with offset from dptr for up to 256 cases.

5084 * added libc directory. The current version of LibC contains string
5085 functions, ctype functions and macros and some functions of the
5086 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
5087 be extensively tested in the future. Standard disclaimer here.
5088 Library is not automatically build yet. But one can build it by
5089 invoking 'make' inside the libc directory.

5100 * (pic16_storeForReturn): optimized return of 0,
5101 * (genCmp): experimental code for new genCmp which uses PIC18's
5102 special compare&skip instructions. Initial tests fail some times
5103 with variables grater than 1 byte in size, so new code is disabled,
5104 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5106 * (genCast): began a fix to optimize the casting of a bit to another
5107 bit, now assigning a bitfield to another bitfield will fail, sorry,

5116 and 1 for banking instruction,
5117 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
5118 caused stop processing pCodes after a inline assembly block,
5119 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

5121 registers when it shouldn't,
5122 * src/pic16/ralloc.c (allocReg): add preliminary support for
5123 supporting a limited set of temporary registers,
5125 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5131 (genFunction): optimize RECEIVE iCodes in reentrant functions
5133 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8130 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
8132 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
8133 loaded with the linker search paths (-L arguments) and the libraries
8134 to be linked with the current source (-l arguments). Changes
8135 currently will affect only the pic16 port.
8136 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8137 include path the port specific paths and port specific libraries,
8138 * gplink command now contains the $3 argument,
8139 * src/pic16/device.h,
8140 * src/pic16/device.c,: structure PIC_device is made public and

8156 Documenting changes from previous commits.
8157 * configure.in (version 1.56),
8158 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8159 when generating output files to configure the pic16 library,
8160 but now I've commented it out, since gputils aren't installed in the
8161 SF compile farm, so library won't compile
8163 * device/lib/Makefile.in (version 1.56): initially I've added in
8164 target 'all' the prerequestive 'model-pic16' so it compiled the
8165 pic16 library, but now I've commented it out for the same reasons
8167 * added targets 'model-pic16' and 'objects-pic16' to compile the
8169 * added target 'port-specific-objects-pic16' to handle the
8170 generated libraries and copy them into the build/ directory
8171 * added target 'clean-intermediate-pic16' to clean intermediate
8172 files into pic16 directory
8173 * in target 'installdirs' added line to create directory pic16 in

8177 added lines to copy all header files to installation path,
8178 * in target 'installdirs' added line create directory for pic16
8179 headers in the installation path

8195 option so that it actually works. Made it specific to the z80, since
8196 the gbz80 doesn't have these kinds of I/O ports.
8198 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8200 * device/include/z180.h,

8224 via literal number. The symbol is placed in the corresponding
8225 position of the data ram
8226 * (pic16_dump_section): relocatable and absolute uninitialized
8227 data are now emitted in sorted order to reduce section naming,
8228 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
8229 weren't marked as being in the access bank,

8306 * (pic16_get_op): modified to use the gpasm modifiers LOW,HIGH and
8307 UPPER for immediate operands,
8308 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
8310 * src/pic16/peeph.def: all peepholes with movff are commented out,
8311 because there is a problem in the pcode peep optimizer,
8312 * src/pic16/ralloc.c: the register allocator can now reuse local
8313 function symbols for another function. This saves register usage.
8314 * src/pic16/ralloc.h: added flag isLocal in structure regs,
8316 Added file src/pic16/NOTES with information about program writing on
8317 the current port version.

8405 include information about variables allocated to the overlay
8408 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8410 * as/mcs51/lkmain.c: Help about -Y option

8420 LEFT_OP (left shift)
8422 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8424 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
8425 (default behaviour).
8427 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8429 A python script to validate compiler diagnostic messages. It can be
8430 used to verify that sdcc complains about bad c source code and
8431 gives a good location of the error.
8432 * support/valdiag/Makefile,
8433 * support/valdiag/valdiag.py,
8434 * support/valdiag/tests/*
8436 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8451 Bug reported from Jesus Calvino-Fraga
8453 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8455 * sdcc.spec: updated
8456 * device/include/Makefile.in: don't install CVS directories
8457 * device/lib/Makefile.in: added removal of CVS directories after install
8458 * doc/Makefile: fixed install, added local_icons
8459 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8460 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8461 * src/ds390/gen.c (genRightShift): fixed bug #870788
8462 * src/SDCCast.c (decorateType): fixed bug #870781
8464 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8466 PIC16 port related changes:
8467 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8468 added variable stackPos,
8470 * gen.c: genCall, assignResultValue: added support for
8471 pushing/retrieving function parameters to/from stack,
8472 genFunction,genEndFunction: setup stack frame for the
8474 genAddrOf: will be changed according to bug 863624
8476 * added files genutils.c and genutils.h which contain gen*
8477 debugged and optimised functions extracted from gen.c
8479 * glue.c: added variable 'externs' which holds extern symbols,
8480 pic16emitRegularMap: is modified to properly handle relocatable
8481 symbols under the new scheme,
8482 pic16createInterruptVect: is modified
8483 pic16printPublics: is modified to emit 'global' assembler directives,
8484 added pic16_printExterns to print extern symbols,
8485 pic16glue: initializes stack/frame pointer in the beginning of
8486 the assembly output. Temporary hack, will be corrected later,
8487 because gplink yet does not support stack and SDCC does not
8488 yet support a type of crt0.o object to create the final binary.
8490 * Removed many lines that contain 8051 legacy code.
8491 * The code is finally placed under a 'code' directive.
8492 * Added port specific options.
8494 * _process_pragma: simplified since now we do not need *special*
8495 include file to define SFR registers. But a separate header
8496 will be needed. This will be developed later.
8497 * _pic16_parseOptions: added, parses port specific options:
8498 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8499 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8500 --preplace-udata-with=
8502 * _pic16_setDefaultOptions: modified to initialize section names,
8503 but hack is temporarly out of order since it needs improvement.
8504 * _pic16_genAssemblerPreamble: configuration words are emitted by
8505 their address instead of their name. This part is incomplete and
8506 supports only the 18Fxx2 devices. Other devices will emit an error
8507 during assembly since they do not contain the same set of config
8509 * _pic16_genIVT: is modified,
8511 * pcode.c: added definitions for some hardware registers that are needed
8513 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8514 All PCI entries are updated. Now LFSR is supported.
8515 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8516 * added pic16_newpCodeOpLit2 to support instructions with
8517 two literal arguments
8518 * pic16_pCode2str: corrected code that emits assembler instructions
8519 with two literal operands and those that have an access bit modifier
8520 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8521 this fixes a bug which caused some labels to be lost, when an
8522 assembler directive was added, i.e. banksel,
8523 * pic16_FixRegisterBanking: improved logic that causes the insertion
8525 * InlineFunction: functions that are called once, are not any more
8526 inlined. This can be a port option in the future,
8528 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8530 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8531 hold the corresponding uninitialized symbols,
8532 * pic16_allocProcessorRegister: registers have explicit marked the
8534 * pic16_allocInternalRegister: registers are explicit marked as
8536 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8537 processing list, so bit registers were lost,
8540 * ralloc.h: added field 'accessBank' and original symbol operand
8541 in register definition,
8542 * removed the field isMapped from register definition,
8544 ** Several functions have been removed from various sources:
8545 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8546 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8547 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8548 pic16_assignRelocatableRegisters
8550 ** others have been introduced:
8551 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8552 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8554 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8556 * support/scripts/inc2h.pl: changed definition of BIT_AT
8557 to emit 'sbit at' instead of 'bit at'. This was a request.
8559 PIC16 port related preliminary changes:
8560 * gen.c: prefixed function popRegFromString with
8561 pic16_ and all references to it corrected
8562 * pcode.c: all pic16_pc_* hardware registers prefixed
8563 with underscore (_),
8564 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8565 * ralloc.c: newReg(): when register is REG_SFR then
8566 set address to rIdx,
8567 pic16_allocProcessorRegister(): marks register wasUsed=0
8568 pic16_writeUsedRegs(): added a call to assign processor
8569 registers via pic16_assignFixedRegisters
8571 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8573 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8574 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8575 variables in unused register banks. Also the SSEG is placed
8576 wherever there is enough space for it, and IDATA can be anywhere
8577 in internal RAM. For now compile using -Wl-Y[stack_size].
8578 The mem file is different for this option as well, since it
8579 makes no sense of talking about DSEG lenght.
8581 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8583 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8584 in certain cases, e.g. when ROM assignment, patch provided
8585 from Albert den Haan.
8587 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

9473 support for standard C idiom of memory mapped variables; for
9474 example, *((xdata int*)0x1234) = 1 is now internally equivalent
9475 to xdata int at 0x1234 tempvar = 1.
9476 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
9477 provided by Akiya ISHIDA

9589 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
9590 fetching of the pointer
9591 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
9592 copied from genNearPointerSet()
9593 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
9594 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

9606 these ports have their own __sdcc_external_start()
9608 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
9610 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9611 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9612 type for bits was changed. It resulted in bit variables becoming
9613 global, which is not permitted in PIC 14 assembly output.
9615 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

9630 A few small changes that speed up the peephole optimizer.
9634 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9636 Try to make the peephole optimizer smarter by maintaining
9637 an association between the assembly source code and the
9638 iCodes that originated them. Put this information to use
9639 with a new peephole rule condition "notVolatile" so that
9640 the rules can be aggressive yet still safe.
9645 * src/mcs51/peeph.def
9647 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9651 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9652 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9653 if the left or right operand symbols have the accuse flag set.
9655 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9657 Changed the type of the result of the ! (NOT) operator to char;
9658 previously it returned the same type as the source. This allows
9659 us to eliminate all the genFloatNot functions (all of its target
9660 implementations were very buggy) since !float can use the same
9663 * src/SDCCicode.c (ast2iCode): ! returns char

9672 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9673 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9674 during interrupts. Ensure WSAVE is located at a shared bank address.
9675 2. Fixed page selection in some places
9676 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9677 the registers name strings.
9678 4. Fixed "signed / unsigned compare" compiler warnings.
9679 5. The PIC port manages its own allocation of the general purpose
9680 registers, but makes no attempt to reuse them. As a result when
9681 compiling it soon runs out of general purpose registers. Some
9682 additional code was added to the files pcode.c and device.c to walk
9683 through the function call tree and rename the registers so that they
9693 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9694 genPlus() & genMinus() when the result is the same as left or right

9700 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9702 Made bitfield a distinct type from bit so that bitfields
9703 convert as per ANSI C and bits retain their traditional
9704 boolean style behaviour. Implemented bitfield support in
9712 * src/ds390/gen.c: bit v bitfield split
9713 * src/z80/gen.c: New support for bitfields
9714 * support/regression/tests/bitfields.c: reenabled z80,
9717 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9719 Rules 246.x, 247.x relate to bitfields, the others speed up
9720 access to xdata mapped I/O devices.
9722 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9724 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9726 Cleaned up genPackBits and genUnpackBits and added two helper
9727 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9728 for literal assignments in genPackBits (thanks to Frieder for
9734 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9736 Fixed bug #748310 (pointer to function type mishandled when the
9737 function name is omitted). Also fixed a SIGSEGV when a function
9738 attribute (reentrant, etc) is used on a non-function or on a
9739 function but misplaced before the parameter list.
9741 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9743 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
9744 * support/Util/SDCCerr.h,

9766 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9768 Made the constant following the "interrupt" keyword optional. If
9769 omitted, the function will not automatically be given an entry
9770 in the interrupt vector table (similar to #pragma NOIV, but
9771 less syntacticly kludgy). The interrupt number is also now
9772 range checked. Also fixed a bug in the high order bit example

9786 * src/SDCCicode.c (operandOperation): rewritten some ops
9787 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
9788 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9790 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9791 be re-activated by defining REDUCE_LITERALS)
9792 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
9793 unsigned, but are signed by default
9794 * src/SDCCval.c (constVal): rearranged
9795 * src/SDCCval.c (valMod): preliminary fix
9796 * src/SDCCval.c (valCastLiteral): use TYPE_* types

10302 added if/endif conditional macros to remove options help
10303 messages from optionsTable when a port is not configured, added
10304 support for the PIc16 port in the ports table, when executing
10305 the compiler with no port specified on command line, a default
10306 port is selected with the new macro DEFAULT_PORT which is
10307 defined in port.h, in setDefaultOptions() linkOptions is removed
10308 from initialization assignment, since now it is a set,
10309 parseCmdLine uses setParseWithComma for linkOptions, in
10310 linkEdit() linkOptions are accessed with new function indexSet()
10311 which returns the i'th item of a set variable. See SDCCset.c, in
10312 linkEdit() when calling buildCmdLine(), added linkOptions as
10313 last argument. Now users can pass arguments to gplink via the
10314 -Wl option, main() uses pic16glue() to glue up pic16 programs

10327 * src/pic16/main.c: __config directives are commented out to stop
10328 gpasm complaining and test the linkage with gplink, _linkCmd and
10329 _asmCmd changed to be more gplink and gpasm friendly
10330 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10331 produced an error when parsed, peep rule 12 is added to utilize
10332 movff, but it is commented out since the pCode does not support
10333 yet a command with 2 address arguments
10335 2003-05-18 <johan AT balder>
10337 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

11385 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
11386 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

11392 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
11393 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
11395 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
11396 * src/mcs51/main.c: removed {bindir}{sep} from aslink
11398 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11400 * in /sdcc/as/mcs51/ changed these files in order to create an
11401 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11402 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11403 following files to include the previous two files: aslink.dsp,
11404 Makefile.aslink, Makefile.bcc, and Makefile.in.
11406 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11407 .adb instead of .cdb
11409 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11411 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11412 value from option --iram-size.
11414 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11416 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11419 2002-09-18 <wiml AT hhhh.org>
11421 * SDCClrange.h: exposed setFromRange() and setToRange()
11422 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11423 packRegsForAccUse() (bug 542397)
11424 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11425 multiple times and emitting the fetch operations more than once
11426 added aopGetUsesAcc() function to allow binary operators to
11427 fetch their operands in the correct order; made genMinus() emit
11428 compact code for X = LITERAL - Y
11430 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11431 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11432 sprintf() in line 1267.
11434 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11435 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11438 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11439 Changes to aslink (All the changes are marked with 'JCF'):
11441 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11444 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11445 area BSEG. Also moves, if possible, the DATA area down into the internal
11446 ram so more space is available.
11448 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11451 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11452 not bytes. Function summary() which creates a memory usage summary
11453 file with extension .mem. Reports of overlaping stack and small stack
11454 size. If the space for the stack is less than 16 bytes aslink trows a
11457 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11458 the 8051. Option 'y' for memory summary output file.
11460 Changes to sdcc (All the changes are marked with 'JCF'):
11462 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11464 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11465 overlaying area for it (uses RegBankUsed[4]).
11467 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11468 bank zero as used by default. By default aslink locates the stack
11469 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11470 the creation of the .mem file. Delegates the allocation of data area
11471 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11472 the begining of the stack area to aslink.
11474 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11475 glue() in SDCCglue.c creates an area for it.
11477 2002-09-03 Borut Razem <borut.razem AT siol.net>
11478 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11479 sdcc/src/pic/glue.c:
11480 introduced atexit() handler for teporay files removal in case of
11481 errors, assertions, ...
11483 2002-08-29 Borut Razem <borut.razem AT siol.net>
11484 * sdcc/support/cpp2/auto-host_vc_in.h:
11485 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11486 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11487 Maybe there is a similar problem with BORLANDC? It should be checked!
11489 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11490 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11491 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11492 was not executed, and the compiler (cl) launched a warning:
11493 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11495 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11496 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11498 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11499 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11501 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11502 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11503 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11504 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11505 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11506 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11507 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11508 - added Release configuration in VS projects
11509 - review of compiler an linker options
11510 - VC .exe files are generated in bin_vc directory, not to interfere
11511 with binaries generated from other projects (cygwin, mingw, bcc ...)
11513 * sdcc/src/yacc.dsp: added
11515 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11516 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11517 and insert the version number definitions from .version
11519 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11521 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11522 added - genarate auto-host.h using auto-host_vc_in.h as template
11525 removed from CVS, generated automatically
11527 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11528 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11530 2002-08-11 Borut Razem <borut.razem AT siol.net>
11531 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11533 2002-08-10 Borut Razem <borut.razem AT siol.net>
11534 * src/SDCCmain.c (main):
11535 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11536 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11537 The consequence was that some temporary files were not removed.
11540 unification of code in functions tempfilename() and tempfile():
11541 function tempnam() is defined in Visual Studio 6.0 and .NET
11543 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11545 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11546 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11547 - removed compiler command line option /WX: Treats all warnings as errors
11548 - update a list of source files, included into the project
11550 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11551 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11552 changed project type to Generic Project so that can be correcly converted to VS.NET project
11554 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11556 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11558 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11560 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11561 added return 0 statements after assert() to make compiler happy
11563 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11564 added newline in the def file to keep MSC compiler satisfied
11566 * sdcc/src/z80/gen.c:
11567 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11568 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11569 - solved MSC error in function aopDump()
11571 * sdcc_vc.h: define PREFIX as "\\sdcc"
11573 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
11574 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
11576 2002-06-22 Scott Dattalo <scott AT dattalo.com>
11577 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
11578 - Rewrote the register banking algorithm.
11579 - Added pCode live-range analysis to registers (for now, only non-used and
11580 singly-used registers optimized away)
11582 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
11584 * 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.
11586 2002-05-10 Scott Dattalo <scott AT dattalo.com>
11587 * src/pic/*: Added support for multiplication. Fixed many,many bugs.
