1528 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1530 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1531 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1533 One basic decision: e.g. src/clean.mk includes further files. In order
1534 to make this work there are two solutions:
1535 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1536 run configure on them. This way they can use
1537 'include $(srcdir)/port-clean.mk'
1538 - always include clean.mk by the Makefile at the same level. To avoid
1539 that `make clean` tries to include and build Makefile.dep the
1540 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1541 implemented, because now even `make uninstall` doesn't create
1542 Makefile.in. clean.mk could be eliminated by pasting it in
1545 * debugger/mcs51/Makefile.in: build own objects from library sources
1546 (SLIB, SDCC) in current directory
1548 * configure, configure.in: renamed --disable-device-lib-build in
1549 --disable-device-lib; added --enable-doc, the required tools are
1550 searched by configure; added result message; the toolchain for the
1551 belonging ports are now only built, if the port is enabled.
1553 * support/regression/*: all output is written in directory gen, because
1554 the fwk and ports directories don't livet in the build tree using vpath
1556 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1557 --disable-device-lib, added --enable-doc, added section VPATH
1559 * sim/ucsim/configure.in,
1560 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1561 z80 are enabled by default
1563 2006-04-24 Raphael Neider <rneider AT web.de>
1565 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1566 to config word, "pic14_"-prefixed some extern functions
1567 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1568 config word has been found
1569 * src/pic/device.h: added prototypes
1570 * src/pic/pcode.c: added "pic14_"-prefix where needed
1571 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
1573 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

1811 2006-04-05 Maarten Brock <sourceforge.brock AT dse.nl>
1813 * src/mcs51/gen.c (genCall): fixed bug 1457608
1815 2006-03-30 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

1820 2006-03-29 Maarten Brock <sourceforge.brock AT dse.nl>
1822 * src/SDCCpeeph.c (operandsLiteral): new, added,

1833 * src/z80/gen.c (genFunction, genEndFunction): fixed bug 1160666,
1834 implemented patch 1120823 Thanks to Willy De la Court (normal
1835 interrupts need an interrupt number now if they are made critical),
1836 and enabled nesting of critical functions though not for gbz80
1837 (genCritical, genEndCritical): added functions
1838 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1839 * src/z80/mappings.i: added "ei" to all mappings
1841 2006-03-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

1844 submitted by the Debian SDCC maintainer Aurelien Jarno:
1845 "Credits goes to Martin Michlmayr, who rebuilt the whole Debian
1846 archive with gcc 4.1 on mips and wrote the patch"
1848 2006-03-16 Raphael Neider <rneider AT web.de>
1850 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
1851 the left operand is shorter than the result (c* = lit-c* + int),
1853 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1856 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1858 * src/.version: increased version number to 2.5.5
1859 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1860 linking is done manually in pic16 port's _linkEdit,
1861 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1862 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1863 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1864 allocate asmop as AOP_ACC,
1865 (aopForRemat): added parameter 'bool result' in function declaration,
1866 (pic16_aopGet): return AOP_ACC when accessing WREG,
1867 (pic16_popGetTempReg): minor modification,
1868 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
1869 'pic16_allocWithIdx',
1870 (genPcall): removed ftype, usage of OP_SYM_TYPE asserted error when
1871 calling function in absolute addresses,
1872 (genAssign): take into account AOP_ACC asmop,
1873 * src/pic16/pcode.c (pic16_newpCodeOpReg): minor modifications,

1876 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
1878 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1879 call to allocReg, not by manually allocating a new one,
1880 (pic16_assignRegisters): now before going through the register
1881 allocating functions mark all registers as free. This eliminates some
1882 side effects resulting from peephole parser done earlier in the backbone
1884 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
1886 * src/SDCCicode.c (geniCodeLogic),

1905 * src/mcs51/gen.c (newAsmop): set asmop.allocated to 1,
1906 (aopForSym, aopOp): increment asmop.allocated if reused,
1907 (freeAsmop): decrement asmop.allocated and check for zero instead of
1909 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
1910 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,
1911 genCmpLt, genAndOp, genOrOp, genAnd, genOr, genXor, genRRC, genRLC,

1934 2006-03-06 Borut Razem <borut.razem AT siol.net>
1936 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
1937 made the linker quiet
1939 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
1941 * src/pic16/gen.c (genPcall): fixed bug #1443644
1942 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1943 which dumps before the function entry point a data byte which represents
1944 the number of the local variables used by the specified function, added
1945 'xinst' for initial support for Extended Instruction Support,
1946 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1947 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1948 port->fun_prefix anymore (may change later),
1949 (genFunction, genEndFunction): do not store/restore local registers for
1950 _main (this should take care the --main-return command line option in
1952 (genOr): removed some legacy pic-port instructions,
1953 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1954 performing operations with SFR's causes data to be written more than
1955 once to each SFR. Perhaps SFRs should be handled in special cases...
1956 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1958 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1959 into account for stack starting position,
1960 (struct OPTIONS pic16_optionsTable): added command line argument
1961 --extended or -y for Extended Instruction Support,
1962 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1963 (deassignLRs): *** perhaps the most important change, old 'for' code
1964 (commented out for reference), didn't account for some registers which
1965 were left marked 'not free' after a pointer operation. The change
1966 reduces register usage a lot in some cases

4323 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
4324 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
4326 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
4328 * device/lib/printf_large.c: removed inline assembly for portability and
4329 readability. Use printf_fast if speed or size are more important.
4330 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4331 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4333 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4335 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4336 prevent compiler warning
4338 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4340 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4341 moved to level 0 and declared as static. Also they are explicit
4342 placed in access bank. This was necessery because some times they
4343 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4344 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4345 optimizations. Currently only compare to unsigned char is implemented,
4346 * src/pic16/gen.c: added fReturnIdx array,
4347 * (struct resolvedIfx) is moved to gen.h and made public,
4348 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4349 * (aopForSym): added an optimization to directly store in stack of
4350 the operand of a SEND iCode,
4351 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4352 but as registers instead (AOP_REG) using the fReturnIdx array,
4353 * (pic16_freeAsmop): remove the freed register from the
4354 _G.sregsAlloc field,
4355 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4356 a compare of 'WREG',
4357 * (pic16_popGetTempRegCond): changed function prototype, now
4358 function takes also a bitVector argument v which holds the current
4359 set of registers that are allocated for stack access by aopForSym,
4360 registers allocated in aopForSym for accessing stack symbols are not
4361 any more part of the functions usedRegs field,
4362 * (genCall): some times aopOp is called for a stack variable to be
4363 send, aopForSym might perform the push, if this is true make sure
4364 that genCall doesn't push the variable twice by testing _G.resDirect,
4365 * (genFunction): changed testing for unspecified interrupt number
4366 from 256 to INTNO_UNSPEC,
4367 * modified selection scheme of frame pointer generation. Previously
4368 if function did use local registers a frame pointer was generated,
4369 now a frame pointer is generated only if function has arguments
4370 (that need PLUSW2 register access), or has stack arguments, or the
4371 compiler is not instructed to omit the frame pointer,
4372 * (genEndFunction): before restoring local registers that were saved
4373 in the function preamble, also restore the registers that *might*
4374 have been allocated for stack access,
4375 * (genRet): removed some old comments,
4376 * (genCmp, the active (RN's) version): added a call to the
4377 pic16_genCmp_special function to perform the compare with a more
4378 robust and optimized way,
4379 * (genInline): a feature has been added in inline code generation,
4380 which allows a wildcard variable substitution when writing inline
4381 assembly. Code is incomplete and experimental therefore undocumented,
4382 * (genCast): changed order of aopOp for result and right to allow
4383 aopForSym to directly load the result if possible,
4384 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4385 perform an optimized compare on some selected special occasions,
4386 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4387 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4388 generate an IVT any more,
4389 * src/pic16/main.c (pic16_optionsTable): added command line option
4391 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4392 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4394 * src/pic16/NOTES: Raphael Neider added in list of active developers
4395 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4396 jumptable_end to prevent bug #,
4397 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4398 inCond and outCond fields,
4399 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4400 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4401 turn off register spilling,
4402 * (packRegsForOneUse): synced with other ports' versions although it
4403 is not used currently,
4404 * (pic16_packRegisters): added an optimization while reading
4405 structure bitfields, some registers may be saved (malloc code is
4406 decreased by 80 bytes)
4408 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4410 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4411 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4412 this can be optimized more?
4414 2005-03-10 Raphael Neider <rneider AT web.de>
4416 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4417 genNearPointerGet): (hopefully) fixed access to bitfields via
4418 pointers (p->bitN = x; and x = p->bitN; failed)
4420 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

4463 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
4464 to keep the correct label reference count when adding/removing references
4465 to labels. A peephole file using this is appended to patch #1144962.

4743 pic16_framepnt_*, pic16_stack_*, pic1_frame_* pointer variables to
4744 access stack and frame pointers. They are initially assigned to
4745 point at pic16_pc_fsr1[lh] and pic16_pc_fsr2[lh] variables and other
4746 accessing SFRs. Updated all occurences of modification of stack or
4747 frame pointer in gen.c and pcode.c,
4748 * src/pic16/ralloc.c (serialRegAssign): fixed two bugs with
4749 assigning of a literal value to pointers,

5052 Adding support for replacing ljmps with sjmps in jumptables
5053 generated for switch statements. For now you need to set the
5054 environment variable SDCC_SJMP_JUMPTABLE to enable this.
5055 Now 4 algorithms for mcs51 jumptable generation are used:
5056 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
5057 addresses loaded pc-relative for up to 112 cases and stack-pushing
5058 target addresses loaded with offset from dptr for up to 256 cases.

5090 * added libc directory. The current version of LibC contains string
5091 functions, ctype functions and macros and some functions of the
5092 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
5093 be extensively tested in the future. Standard disclaimer here.
5094 Library is not automatically build yet. But one can build it by

5106 * (pic16_storeForReturn): optimized return of 0,
5107 * (genCmp): experimental code for new genCmp which uses PIC18's
5108 special compare&skip instructions. Initial tests fail some times
5109 with variables grater than 1 byte in size, so new code is disabled,
5110 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5112 * (genCast): began a fix to optimize the casting of a bit to another
5113 bit, now assigning a bitfield to another bitfield will fail, sorry,

5122 and 1 for banking instruction,
5123 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
5124 caused stop processing pCodes after a inline assembly block,
5125 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

5127 registers when it shouldn't,
5128 * src/pic16/ralloc.c (allocReg): add preliminary support for
5129 supporting a limited set of temporary registers,
5131 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8136 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
8138 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
8139 loaded with the linker search paths (-L arguments) and the libraries
8140 to be linked with the current source (-l arguments). Changes
8141 currently will affect only the pic16 port.
8142 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8143 include path the port specific paths and port specific libraries,
8144 * gplink command now contains the $3 argument,
8145 * src/pic16/device.h,
8146 * src/pic16/device.c,: structure PIC_device is made public and

8162 Documenting changes from previous commits.
8163 * configure.in (version 1.56),
8164 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8165 when generating output files to configure the pic16 library,
8166 but now I've commented it out, since gputils aren't installed in the
8167 SF compile farm, so library won't compile
8169 * device/lib/Makefile.in (version 1.56): initially I've added in
8170 target 'all' the prerequestive 'model-pic16' so it compiled the
8171 pic16 library, but now I've commented it out for the same reasons
8173 * added targets 'model-pic16' and 'objects-pic16' to compile the
8175 * added target 'port-specific-objects-pic16' to handle the
8176 generated libraries and copy them into the build/ directory
8177 * added target 'clean-intermediate-pic16' to clean intermediate
8178 files into pic16 directory
8179 * in target 'installdirs' added line to create directory pic16 in
8180 the installation path

8183 added lines to copy all header files to installation path,
8184 * in target 'installdirs' added line create directory for pic16
8185 headers in the installation path

8201 option so that it actually works. Made it specific to the z80, since
8202 the gbz80 doesn't have these kinds of I/O ports.
8204 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8206 * device/include/z180.h,

8230 via literal number. The symbol is placed in the corresponding
8231 position of the data ram
8232 * (pic16_dump_section): relocatable and absolute uninitialized
8233 data are now emitted in sorted order to reduce section naming,
8234 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
8235 weren't marked as being in the access bank,

8312 * (pic16_get_op): modified to use the gpasm modifiers LOW,HIGH and
8313 UPPER for immediate operands,
8314 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
8316 * src/pic16/peeph.def: all peepholes with movff are commented out,
8317 because there is a problem in the pcode peep optimizer,
8318 * src/pic16/ralloc.c: the register allocator can now reuse local
8319 function symbols for another function. This saves register usage.
8320 * src/pic16/ralloc.h: added flag isLocal in structure regs,
8322 Added file src/pic16/NOTES with information about program writing on
8323 the current port version.

8411 include information about variables allocated to the overlay
8414 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8416 * as/mcs51/lkmain.c: Help about -Y option

8426 LEFT_OP (left shift)
8428 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8430 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
8431 (default behaviour).
8433 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8435 A python script to validate compiler diagnostic messages. It can be
8436 used to verify that sdcc complains about bad c source code and
8437 gives a good location of the error.
8438 * support/valdiag/Makefile,
8439 * support/valdiag/valdiag.py,
8440 * support/valdiag/tests/*
8442 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8457 Bug reported from Jesus Calvino-Fraga
8459 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8461 * sdcc.spec: updated
8462 * device/include/Makefile.in: don't install CVS directories
8463 * device/lib/Makefile.in: added removal of CVS directories after install
8464 * doc/Makefile: fixed install, added local_icons
8465 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8466 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8467 * src/ds390/gen.c (genRightShift): fixed bug #870788
8468 * src/SDCCast.c (decorateType): fixed bug #870781
8470 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8472 PIC16 port related changes:
8473 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8474 added variable stackPos,
8476 * gen.c: genCall, assignResultValue: added support for
8477 pushing/retrieving function parameters to/from stack,
8478 genFunction,genEndFunction: setup stack frame for the
8480 genAddrOf: will be changed according to bug 863624
8482 * added files genutils.c and genutils.h which contain gen*
8483 debugged and optimised functions extracted from gen.c
8485 * glue.c: added variable 'externs' which holds extern symbols,
8486 pic16emitRegularMap: is modified to properly handle relocatable
8487 symbols under the new scheme,
8488 pic16createInterruptVect: is modified
8489 pic16printPublics: is modified to emit 'global' assembler directives,
8490 added pic16_printExterns to print extern symbols,
8491 pic16glue: initializes stack/frame pointer in the beginning of
8492 the assembly output. Temporary hack, will be corrected later,
8493 because gplink yet does not support stack and SDCC does not
8494 yet support a type of crt0.o object to create the final binary.
8496 * Removed many lines that contain 8051 legacy code.
8497 * The code is finally placed under a 'code' directive.
8498 * Added port specific options.
8500 * _process_pragma: simplified since now we do not need *special*
8501 include file to define SFR registers. But a separate header
8502 will be needed. This will be developed later.
8503 * _pic16_parseOptions: added, parses port specific options:
8504 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8505 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8506 --preplace-udata-with=
8508 * _pic16_setDefaultOptions: modified to initialize section names,
8509 but hack is temporarly out of order since it needs improvement.
8510 * _pic16_genAssemblerPreamble: configuration words are emitted by
8511 their address instead of their name. This part is incomplete and
8512 supports only the 18Fxx2 devices. Other devices will emit an error
8513 during assembly since they do not contain the same set of config
8515 * _pic16_genIVT: is modified,
8517 * pcode.c: added definitions for some hardware registers that are needed
8519 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8520 All PCI entries are updated. Now LFSR is supported.
8521 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8522 * added pic16_newpCodeOpLit2 to support instructions with
8523 two literal arguments
8524 * pic16_pCode2str: corrected code that emits assembler instructions
8525 with two literal operands and those that have an access bit modifier
8526 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8527 this fixes a bug which caused some labels to be lost, when an
8528 assembler directive was added, i.e. banksel,
8529 * pic16_FixRegisterBanking: improved logic that causes the insertion
8531 * InlineFunction: functions that are called once, are not any more
8532 inlined. This can be a port option in the future,
8534 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8536 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8537 hold the corresponding uninitialized symbols,
8538 * pic16_allocProcessorRegister: registers have explicit marked the
8540 * pic16_allocInternalRegister: registers are explicit marked as
8542 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8543 processing list, so bit registers were lost,
8546 * ralloc.h: added field 'accessBank' and original symbol operand
8547 in register definition,
8548 * removed the field isMapped from register definition,
8550 ** Several functions have been removed from various sources:
8551 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8552 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8553 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8554 pic16_assignRelocatableRegisters
8556 ** others have been introduced:
8557 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8558 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8560 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8562 * support/scripts/inc2h.pl: changed definition of BIT_AT
8563 to emit 'sbit at' instead of 'bit at'. This was a request.
8565 PIC16 port related preliminary changes:
8566 * gen.c: prefixed function popRegFromString with
8567 pic16_ and all references to it corrected
8568 * pcode.c: all pic16_pc_* hardware registers prefixed
8569 with underscore (_),
8570 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8571 * ralloc.c: newReg(): when register is REG_SFR then
8572 set address to rIdx,
8573 pic16_allocProcessorRegister(): marks register wasUsed=0
8574 pic16_writeUsedRegs(): added a call to assign processor
8575 registers via pic16_assignFixedRegisters
8577 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8579 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8580 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8581 variables in unused register banks. Also the SSEG is placed
8582 wherever there is enough space for it, and IDATA can be anywhere
8583 in internal RAM. For now compile using -Wl-Y[stack_size].
8584 The mem file is different for this option as well, since it
8585 makes no sense of talking about DSEG lenght.
8587 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8589 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8590 in certain cases, e.g. when ROM assignment, patch provided
8591 from Albert den Haan.
8593 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

9479 support for standard C idiom of memory mapped variables; for
9480 example, *((xdata int*)0x1234) = 1 is now internally equivalent
9481 to xdata int at 0x1234 tempvar = 1.
9482 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
9483 provided by Akiya ISHIDA

9595 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
9596 fetching of the pointer
9597 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
9598 copied from genNearPointerSet()
9599 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
9600 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

9614 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
9616 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9617 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9618 type for bits was changed. It resulted in bit variables becoming
9619 global, which is not permitted in PIC 14 assembly output.
9621 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

9636 A few small changes that speed up the peephole optimizer.
9640 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9642 Try to make the peephole optimizer smarter by maintaining
9643 an association between the assembly source code and the
9644 iCodes that originated them. Put this information to use
9645 with a new peephole rule condition "notVolatile" so that
9646 the rules can be aggressive yet still safe.
9651 * src/mcs51/peeph.def
9653 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9657 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9658 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9659 if the left or right operand symbols have the accuse flag set.
9661 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9663 Changed the type of the result of the ! (NOT) operator to char;
9664 previously it returned the same type as the source. This allows
9665 us to eliminate all the genFloatNot functions (all of its target
9666 implementations were very buggy) since !float can use the same

9678 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9679 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9680 during interrupts. Ensure WSAVE is located at a shared bank address.
9681 2. Fixed page selection in some places
9682 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9683 the registers name strings.
9684 4. Fixed "signed / unsigned compare" compiler warnings.
9685 5. The PIC port manages its own allocation of the general purpose
9686 registers, but makes no attempt to reuse them. As a result when
9687 compiling it soon runs out of general purpose registers. Some
9688 additional code was added to the files pcode.c and device.c to walk
9689 through the function call tree and rename the registers so that they
9699 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

9706 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9708 Made bitfield a distinct type from bit so that bitfields
9709 convert as per ANSI C and bits retain their traditional
9710 boolean style behaviour. Implemented bitfield support in
9718 * src/ds390/gen.c: bit v bitfield split
9719 * src/z80/gen.c: New support for bitfields
9720 * support/regression/tests/bitfields.c: reenabled z80,
9723 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9725 Rules 246.x, 247.x relate to bitfields, the others speed up
9726 access to xdata mapped I/O devices.
9728 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9730 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9732 Cleaned up genPackBits and genUnpackBits and added two helper
9733 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9734 for literal assignments in genPackBits (thanks to Frieder for
9740 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9742 Fixed bug #748310 (pointer to function type mishandled when the
9743 function name is omitted). Also fixed a SIGSEGV when a function
9744 attribute (reentrant, etc) is used on a non-function or on a
9745 function but misplaced before the parameter list.
9747 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9749 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
9750 * support/Util/SDCCerr.h,

9772 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9774 Made the constant following the "interrupt" keyword optional. If
9775 omitted, the function will not automatically be given an entry
9776 in the interrupt vector table (similar to #pragma NOIV, but
9777 less syntacticly kludgy). The interrupt number is also now
9778 range checked. Also fixed a bug in the high order bit example

10308 added if/endif conditional macros to remove options help
10309 messages from optionsTable when a port is not configured, added
10310 support for the PIc16 port in the ports table, when executing
10311 the compiler with no port specified on command line, a default
10312 port is selected with the new macro DEFAULT_PORT which is
10313 defined in port.h, in setDefaultOptions() linkOptions is removed
10314 from initialization assignment, since now it is a set,
10315 parseCmdLine uses setParseWithComma for linkOptions, in
10316 linkEdit() linkOptions are accessed with new function indexSet()
10317 which returns the i'th item of a set variable. See SDCCset.c, in
10318 linkEdit() when calling buildCmdLine(), added linkOptions as
10319 last argument. Now users can pass arguments to gplink via the
10320 -Wl option, main() uses pic16glue() to glue up pic16 programs

10334 gpasm complaining and test the linkage with gplink, _linkCmd and
10335 _asmCmd changed to be more gplink and gpasm friendly
10336 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10337 produced an error when parsed, peep rule 12 is added to utilize
10338 movff, but it is commented out since the pCode does not support
10339 yet a command with 2 address arguments
10341 2003-05-18 <johan AT balder>
10343 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

11380 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
11381 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests

11391 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
11392 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

11398 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
11399 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
11401 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
11402 * src/mcs51/main.c: removed {bindir}{sep} from aslink
11404 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11406 * in /sdcc/as/mcs51/ changed these files in order to create an
11407 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11408 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11409 following files to include the previous two files: aslink.dsp,
11410 Makefile.aslink, Makefile.bcc, and Makefile.in.
11412 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11413 .adb instead of .cdb
11415 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11417 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11418 value from option --iram-size.
11420 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11422 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11425 2002-09-18 <wiml AT hhhh.org>
11427 * SDCClrange.h: exposed setFromRange() and setToRange()
11428 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11429 packRegsForAccUse() (bug 542397)
11430 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11431 multiple times and emitting the fetch operations more than once
11432 added aopGetUsesAcc() function to allow binary operators to
11433 fetch their operands in the correct order; made genMinus() emit
11434 compact code for X = LITERAL - Y
11436 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11437 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11438 sprintf() in line 1267.
11440 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11441 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11444 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11445 Changes to aslink (All the changes are marked with 'JCF'):
11447 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11450 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11451 area BSEG. Also moves, if possible, the DATA area down into the internal
11452 ram so more space is available.
11454 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11457 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11458 not bytes. Function summary() which creates a memory usage summary
11459 file with extension .mem. Reports of overlaping stack and small stack
11460 size. If the space for the stack is less than 16 bytes aslink trows a
11463 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11464 the 8051. Option 'y' for memory summary output file.
11466 Changes to sdcc (All the changes are marked with 'JCF'):
11468 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11470 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11471 overlaying area for it (uses RegBankUsed[4]).
11473 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11474 bank zero as used by default. By default aslink locates the stack
11475 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11476 the creation of the .mem file. Delegates the allocation of data area
11477 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11478 the begining of the stack area to aslink.
11480 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11481 glue() in SDCCglue.c creates an area for it.
11483 2002-09-03 Borut Razem <borut.razem AT siol.net>
11484 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11485 sdcc/src/pic/glue.c:
11486 introduced atexit() handler for teporay files removal in case of
11487 errors, assertions, ...
11489 2002-08-29 Borut Razem <borut.razem AT siol.net>
11490 * sdcc/support/cpp2/auto-host_vc_in.h:
11491 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11492 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11493 Maybe there is a similar problem with BORLANDC? It should be checked!
11495 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11496 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11497 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11498 was not executed, and the compiler (cl) launched a warning:
11499 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11501 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11502 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11504 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11505 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11507 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11508 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11509 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11510 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11511 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11512 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11513 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11514 - added Release configuration in VS projects
11515 - review of compiler an linker options
11516 - VC .exe files are generated in bin_vc directory, not to interfere
11517 with binaries generated from other projects (cygwin, mingw, bcc ...)
11519 * sdcc/src/yacc.dsp: added
11521 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11522 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11523 and insert the version number definitions from .version
11525 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11527 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11528 added - genarate auto-host.h using auto-host_vc_in.h as template
11531 removed from CVS, generated automatically
11533 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11534 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11536 2002-08-11 Borut Razem <borut.razem AT siol.net>
11537 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11539 2002-08-10 Borut Razem <borut.razem AT siol.net>
11540 * src/SDCCmain.c (main):
11541 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11542 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11543 The consequence was that some temporary files were not removed.
11546 unification of code in functions tempfilename() and tempfile():
11547 function tempnam() is defined in Visual Studio 6.0 and .NET
11549 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11551 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11552 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11553 - removed compiler command line option /WX: Treats all warnings as errors
11554 - update a list of source files, included into the project
11556 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11557 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11558 changed project type to Generic Project so that can be correcly converted to VS.NET project
11560 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11562 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11564 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11566 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11567 added return 0 statements after assert() to make compiler happy
11569 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11570 added newline in the def file to keep MSC compiler satisfied
11572 * sdcc/src/z80/gen.c:
11573 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11574 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11575 - solved MSC error in function aopDump()
11577 * sdcc_vc.h: define PREFIX as "\\sdcc"
11579 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
11580 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
11582 2002-06-22 Scott Dattalo <scott AT dattalo.com>
11583 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
11584 - Rewrote the register banking algorithm.
11585 - Added pCode live-range analysis to registers (for now, only non-used and
11586 singly-used registers optimized away)
11588 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
11590 * 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.
11592 2002-05-10 Scott Dattalo <scott AT dattalo.com>
11593 * src/pic/*: Added support for multiplication. Fixed many,many bugs.

11605 2002-04-15 Michael Hope <michaelh AT vroom>
11607 * device/lib/z80/printf.c (sprintf): Added.
11609 * src/z80/ralloc.c (packRegisters): Disabled pack HL use for GB as it's broken.
11611 * src/z80/peeph.def: Added transpose redundent load rule.
