1587 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1589 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1590 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1592 One basic decision: e.g. src/clean.mk includes further files. In order
1593 to make this work there are two solutions:
1594 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1595 run configure on them. This way they can use
1596 'include $(srcdir)/port-clean.mk'
1597 - always include clean.mk by the Makefile at the same level. To avoid
1598 that `make clean` tries to include and build Makefile.dep the
1599 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1600 implemented, because now even `make uninstall` doesn't create
1601 Makefile.in. clean.mk could be eliminated by pasting it in
1604 * debugger/mcs51/Makefile.in: build own objects from library sources
1605 (SLIB, SDCC) in current directory
1607 * configure, configure.in: renamed --disable-device-lib-build in
1608 --disable-device-lib; added --enable-doc, the required tools are
1609 searched by configure; added result message; the toolchain for the
1610 belonging ports are now only built, if the port is enabled.
1612 * support/regression/*: all output is written in directory gen, because
1613 the fwk and ports directories don't livet in the build tree using vpath
1615 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1616 --disable-device-lib, added --enable-doc, added section VPATH
1618 * sim/ucsim/configure.in,
1619 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1620 z80 are enabled by default
1622 2006-04-24 Raphael Neider <rneider AT web.de>
1624 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1625 to config word, "pic14_"-prefixed some extern functions
1626 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1627 config word has been found
1628 * src/pic/device.h: added prototypes
1629 * src/pic/pcode.c: added "pic14_"-prefix where needed
1630 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
1632 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

1635 (pic14createInterruptVect): moved generating __config directives away

1646 fixes #1469504 and #1474602,
1647 (pCodeRegOptimizeRegUsage): fixed typo in comment

1870 2006-04-05 Maarten Brock <sourceforge.brock AT dse.nl>
1872 * src/mcs51/gen.c (genCall): fixed bug 1457608
1874 2006-03-30 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

1893 implemented patch 1120823 Thanks to Willy De la Court (normal
1894 interrupts need an interrupt number now if they are made critical),
1895 and enabled nesting of critical functions though not for gbz80
1896 (genCritical, genEndCritical): added functions
1897 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1898 * src/z80/mappings.i: added "ei" to all mappings

1910 the left operand is shorter than the result (c* = lit-c* + int),
1912 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1915 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1917 * src/.version: increased version number to 2.5.5
1918 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1919 linking is done manually in pic16 port's _linkEdit,
1920 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1921 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1922 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1923 allocate asmop as AOP_ACC,
1924 (aopForRemat): added parameter 'bool result' in function declaration,
1925 (pic16_aopGet): return AOP_ACC when accessing WREG,
1926 (pic16_popGetTempReg): minor modification,

1937 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1938 call to allocReg, not by manually allocating a new one,
1939 (pic16_assignRegisters): now before going through the register
1940 allocating functions mark all registers as free. This eliminates some
1941 side effects resulting from peephole parser done earlier in the backbone
1943 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

2001 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
2002 which dumps before the function entry point a data byte which represents
2003 the number of the local variables used by the specified function, added
2004 'xinst' for initial support for Extended Instruction Support,
2005 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
2006 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
2007 port->fun_prefix anymore (may change later),
2008 (genFunction, genEndFunction): do not store/restore local registers for
2009 _main (this should take care the --main-return command line option in
2011 (genOr): removed some legacy pic-port instructions,
2012 * src/pic16/genarith.c (genAddLit): re-enabled old code because
2013 performing operations with SFR's causes data to be written more than
2014 once to each SFR. Perhaps SFRs should be handled in special cases...
2015 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
2017 * src/pic16/main.c (_process_pragma): stack bound checking did not take
2018 into account for stack starting position,

2022 (deassignLRs): *** perhaps the most important change, old 'for' code
2023 (commented out for reference), didn't account for some registers which
2024 were left marked 'not free' after a pointer operation. The change
2025 reduces register usage a lot in some cases

4322 2005-03-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4324 * src/port.h (struct PORT),

4353 immedDom() returning wrong block; probably fixes bug #1160833)
4355 2005-03-20 Borut Razem <borut.razem AT siol.net>
4357 * support/scripts/inc2h.pl: WIN32 port
4359 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
4361 * device/lib/makefile.in: added abs.c and labs.c
4363 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
4365 * device/include/stdint.h: added
4366 * device/lib/abs.c: added
4367 * device/lib/labs.c: added
4368 * device/include/stdlib.h: added abs() and labs() prototypes
4369 * device/lib/libsdcc.lib: added abs and labs
4370 * device/include/float.h,
4371 * device/lib/_fsmul.c,
4372 * device/lib/printf_fast.c,

4375 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4377 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
4380 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4383 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
4385 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
4387 * device/lib/printf_large.c: removed inline assembly for portability and
4388 readability. Use printf_fast if speed or size are more important.
4389 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4390 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4392 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4394 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4395 prevent compiler warning
4397 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4399 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4400 moved to level 0 and declared as static. Also they are explicit
4401 placed in access bank. This was necessery because some times they
4402 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4403 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4404 optimizations. Currently only compare to unsigned char is implemented,
4405 * src/pic16/gen.c: added fReturnIdx array,
4406 * (struct resolvedIfx) is moved to gen.h and made public,
4407 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4408 * (aopForSym): added an optimization to directly store in stack of
4409 the operand of a SEND iCode,
4410 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4411 but as registers instead (AOP_REG) using the fReturnIdx array,
4412 * (pic16_freeAsmop): remove the freed register from the
4413 _G.sregsAlloc field,
4414 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4415 a compare of 'WREG',
4416 * (pic16_popGetTempRegCond): changed function prototype, now
4417 function takes also a bitVector argument v which holds the current
4418 set of registers that are allocated for stack access by aopForSym,
4419 registers allocated in aopForSym for accessing stack symbols are not
4420 any more part of the functions usedRegs field,
4421 * (genCall): some times aopOp is called for a stack variable to be
4422 send, aopForSym might perform the push, if this is true make sure
4423 that genCall doesn't push the variable twice by testing _G.resDirect,
4424 * (genFunction): changed testing for unspecified interrupt number
4425 from 256 to INTNO_UNSPEC,
4426 * modified selection scheme of frame pointer generation. Previously
4427 if function did use local registers a frame pointer was generated,
4428 now a frame pointer is generated only if function has arguments
4429 (that need PLUSW2 register access), or has stack arguments, or the
4430 compiler is not instructed to omit the frame pointer,
4431 * (genEndFunction): before restoring local registers that were saved
4432 in the function preamble, also restore the registers that *might*
4433 have been allocated for stack access,
4434 * (genRet): removed some old comments,
4435 * (genCmp, the active (RN's) version): added a call to the
4436 pic16_genCmp_special function to perform the compare with a more
4437 robust and optimized way,
4438 * (genInline): a feature has been added in inline code generation,
4439 which allows a wildcard variable substitution when writing inline
4440 assembly. Code is incomplete and experimental therefore undocumented,
4441 * (genCast): changed order of aopOp for result and right to allow
4442 aopForSym to directly load the result if possible,
4443 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4444 perform an optimized compare on some selected special occasions,
4445 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4446 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4447 generate an IVT any more,
4448 * src/pic16/main.c (pic16_optionsTable): added command line option
4450 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4451 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4453 * src/pic16/NOTES: Raphael Neider added in list of active developers
4454 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4455 jumptable_end to prevent bug #,
4456 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4457 inCond and outCond fields,
4458 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4459 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4460 turn off register spilling,
4461 * (packRegsForOneUse): synced with other ports' versions although it
4462 is not used currently,
4463 * (pic16_packRegisters): added an optimization while reading
4464 structure bitfields, some registers may be saved (malloc code is
4465 decreased by 80 bytes)
4467 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4469 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4470 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4471 this can be optimized more?
4473 2005-03-10 Raphael Neider <rneider AT web.de>
4475 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4476 genNearPointerGet): (hopefully) fixed access to bitfields via
4477 pointers (p->bitN = x; and x = p->bitN; failed)
4479 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
4481 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

4522 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
4523 to keep the correct label reference count when adding/removing references
4524 to labels. A peephole file using this is appended to patch #1144962.

4667 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
4668 this might fix SIGSEGVs on MinGW...
4669 * src/SDCCopt.c (killDeadCode): restored original behaviour
4670 (volatile operands might get thrown away though)
4672 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

4757 * (genNearPointer[GS]et): enforce reloading of FSR0 (was still
4758 used uninitialized in some cases)

5111 Adding support for replacing ljmps with sjmps in jumptables
5112 generated for switch statements. For now you need to set the
5113 environment variable SDCC_SJMP_JUMPTABLE to enable this.
5114 Now 4 algorithms for mcs51 jumptable generation are used:
5115 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
5116 addresses loaded pc-relative for up to 112 cases and stack-pushing
5117 target addresses loaded with offset from dptr for up to 256 cases.

5147 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
5149 * added libc directory. The current version of LibC contains string
5150 functions, ctype functions and macros and some functions of the
5151 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
5152 be extensively tested in the future. Standard disclaimer here.
5153 Library is not automatically build yet. But one can build it by
5154 invoking 'make' inside the libc directory.
5155 * added ADC library under libio. Preliminary version yet.

5164 * (genUminusFloat): fixed for pic16, ported code from mcs51,
5165 * (pic16_storeForReturn): optimized return of 0,
5166 * (genCmp): experimental code for new genCmp which uses PIC18's
5167 special compare&skip instructions. Initial tests fail some times
5168 with variables grater than 1 byte in size, so new code is disabled,
5169 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5171 * (genCast): began a fix to optimize the casting of a bit to another
5172 bit, now assigning a bitfield to another bitfield will fail, sorry,
5173 * src/pic16/main.c: disabled the use of lr-support feature,
5174 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

5177 bits with offset (case PO_GPR_BIT),
5178 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
5180 * (isBankInstruction): modified to return 0 for no banking instruction,
5181 and 1 for banking instruction,
5182 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,

8195 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
8197 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
8198 loaded with the linker search paths (-L arguments) and the libraries
8199 to be linked with the current source (-l arguments). Changes
8200 currently will affect only the pic16 port.
8201 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8202 include path the port specific paths and port specific libraries,
8203 * gplink command now contains the $3 argument,
8204 * src/pic16/device.h,
8205 * src/pic16/device.c,: structure PIC_device is made public and
8206 renamed to PIC16_device, the same for variable Pics which is renamed

8221 Documenting changes from previous commits.
8222 * configure.in (version 1.56),
8223 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8224 when generating output files to configure the pic16 library,
8225 but now I've commented it out, since gputils aren't installed in the
8226 SF compile farm, so library won't compile
8228 * device/lib/Makefile.in (version 1.56): initially I've added in
8229 target 'all' the prerequestive 'model-pic16' so it compiled the
8230 pic16 library, but now I've commented it out for the same reasons
8232 * added targets 'model-pic16' and 'objects-pic16' to compile the
8234 * added target 'port-specific-objects-pic16' to handle the
8235 generated libraries and copy them into the build/ directory
8236 * added target 'clean-intermediate-pic16' to clean intermediate
8237 files into pic16 directory
8238 * in target 'installdirs' added line to create directory pic16 in
8239 the installation path
8241 * device/include/Makefile.in (version 1.11): in target 'install'
8242 added lines to copy all header files to installation path,
8243 * in target 'installdirs' added line create directory for pic16
8244 headers in the installation path

8259 * src/z80/main.c (_parseOptions): fixed the portmode= command line
8260 option so that it actually works. Made it specific to the z80, since
8261 the gbz80 doesn't have these kinds of I/O ports.
8263 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8265 * device/include/z180.h,

8294 weren't marked as being in the access bank,
8296 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
8298 Added portion of GNU PIC Library under the directory
8299 device/include/pic16 and device/lib/pic16. These files
8300 contain the declarations of SFRs for the PIC18Fxx2 devices.
8301 The directory is initialized via configure from toplevel.
8303 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>

8331 all over. Telling LaTeX to be less strict with word spacing
8332 to better keep the right margin. Changed some notes about
8333 maintainance of the ports in section 3.2.1 - is it OK like this?
8335 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

8375 * src/pic16/peeph.def: all peepholes with movff are commented out,
8376 because there is a problem in the pcode peep optimizer,
8377 * src/pic16/ralloc.c: the register allocator can now reuse local

8470 include information about variables allocated to the overlay
8473 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8475 * as/mcs51/lkmain.c: Help about -Y option

8487 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8489 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
8490 (default behaviour).
8492 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8494 A python script to validate compiler diagnostic messages. It can be
8495 used to verify that sdcc complains about bad c source code and
8496 gives a good location of the error.
8497 * support/valdiag/Makefile,
8498 * support/valdiag/valdiag.py,
8499 * support/valdiag/tests/*
8501 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8516 Bug reported from Jesus Calvino-Fraga
8518 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8520 * sdcc.spec: updated
8521 * device/include/Makefile.in: don't install CVS directories
8522 * device/lib/Makefile.in: added removal of CVS directories after install
8523 * doc/Makefile: fixed install, added local_icons
8524 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8525 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8526 * src/ds390/gen.c (genRightShift): fixed bug #870788
8527 * src/SDCCast.c (decorateType): fixed bug #870781
8529 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8531 PIC16 port related changes:
8532 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8533 added variable stackPos,
8535 * gen.c: genCall, assignResultValue: added support for
8536 pushing/retrieving function parameters to/from stack,
8537 genFunction,genEndFunction: setup stack frame for the
8539 genAddrOf: will be changed according to bug 863624
8541 * added files genutils.c and genutils.h which contain gen*
8542 debugged and optimised functions extracted from gen.c
8544 * glue.c: added variable 'externs' which holds extern symbols,
8545 pic16emitRegularMap: is modified to properly handle relocatable
8546 symbols under the new scheme,
8547 pic16createInterruptVect: is modified
8548 pic16printPublics: is modified to emit 'global' assembler directives,
8549 added pic16_printExterns to print extern symbols,
8550 pic16glue: initializes stack/frame pointer in the beginning of
8551 the assembly output. Temporary hack, will be corrected later,
8552 because gplink yet does not support stack and SDCC does not
8553 yet support a type of crt0.o object to create the final binary.
8555 * Removed many lines that contain 8051 legacy code.
8556 * The code is finally placed under a 'code' directive.
8557 * Added port specific options.
8559 * _process_pragma: simplified since now we do not need *special*
8560 include file to define SFR registers. But a separate header
8561 will be needed. This will be developed later.
8562 * _pic16_parseOptions: added, parses port specific options:
8563 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8564 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8565 --preplace-udata-with=
8567 * _pic16_setDefaultOptions: modified to initialize section names,
8568 but hack is temporarly out of order since it needs improvement.
8569 * _pic16_genAssemblerPreamble: configuration words are emitted by
8570 their address instead of their name. This part is incomplete and
8571 supports only the 18Fxx2 devices. Other devices will emit an error
8572 during assembly since they do not contain the same set of config
8574 * _pic16_genIVT: is modified,
8576 * pcode.c: added definitions for some hardware registers that are needed
8578 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8579 All PCI entries are updated. Now LFSR is supported.
8580 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8581 * added pic16_newpCodeOpLit2 to support instructions with
8582 two literal arguments
8583 * pic16_pCode2str: corrected code that emits assembler instructions
8584 with two literal operands and those that have an access bit modifier
8585 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8586 this fixes a bug which caused some labels to be lost, when an
8587 assembler directive was added, i.e. banksel,
8588 * pic16_FixRegisterBanking: improved logic that causes the insertion
8590 * InlineFunction: functions that are called once, are not any more
8591 inlined. This can be a port option in the future,
8593 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8595 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8596 hold the corresponding uninitialized symbols,
8597 * pic16_allocProcessorRegister: registers have explicit marked the
8599 * pic16_allocInternalRegister: registers are explicit marked as
8601 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8602 processing list, so bit registers were lost,
8605 * ralloc.h: added field 'accessBank' and original symbol operand
8606 in register definition,
8607 * removed the field isMapped from register definition,
8609 ** Several functions have been removed from various sources:
8610 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8611 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8612 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8613 pic16_assignRelocatableRegisters
8615 ** others have been introduced:
8616 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8617 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8619 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8621 * support/scripts/inc2h.pl: changed definition of BIT_AT
8622 to emit 'sbit at' instead of 'bit at'. This was a request.
8624 PIC16 port related preliminary changes:
8625 * gen.c: prefixed function popRegFromString with
8626 pic16_ and all references to it corrected
8627 * pcode.c: all pic16_pc_* hardware registers prefixed
8628 with underscore (_),
8629 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8630 * ralloc.c: newReg(): when register is REG_SFR then
8631 set address to rIdx,
8632 pic16_allocProcessorRegister(): marks register wasUsed=0
8633 pic16_writeUsedRegs(): added a call to assign processor
8634 registers via pic16_assignFixedRegisters
8636 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8638 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8639 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8640 variables in unused register banks. Also the SSEG is placed
8641 wherever there is enough space for it, and IDATA can be anywhere
8642 in internal RAM. For now compile using -Wl-Y[stack_size].
8643 The mem file is different for this option as well, since it
8644 makes no sense of talking about DSEG lenght.
8646 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8648 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8649 in certain cases, e.g. when ROM assignment, patch provided
8650 from Albert den Haan.
8652 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8798 without the non-interrupt code having to disable interrupts)
8800 2003-12-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8802 * src/SDCCicode.c (geniCodeAdd),

8895 it breaks with bitfields, extern declarations, and gcse analysis.
8896 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
8897 could be assigned through a pointer, so don't complain.

9675 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9676 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9677 type for bits was changed. It resulted in bit variables becoming

9695 A few small changes that speed up the peephole optimizer.
9699 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9701 Try to make the peephole optimizer smarter by maintaining
9702 an association between the assembly source code and the
9703 iCodes that originated them. Put this information to use
9704 with a new peephole rule condition "notVolatile" so that
9705 the rules can be aggressive yet still safe.
9710 * src/mcs51/peeph.def
9712 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9716 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9717 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9718 if the left or right operand symbols have the accuse flag set.
9720 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9722 Changed the type of the result of the ! (NOT) operator to char;
9723 previously it returned the same type as the source. This allows
9724 us to eliminate all the genFloatNot functions (all of its target
9725 implementations were very buggy) since !float can use the same
9728 * src/SDCCicode.c (ast2iCode): ! returns char

9730 * src/ds390/gen.c (genNot, genNotFloat),
9731 * src/z80/gen.c (genNot, genNotFloat),
9732 * src/pic/gen.c (genNot, genNotFloat),

9735 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
9737 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9738 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9739 during interrupts. Ensure WSAVE is located at a shared bank address.
9740 2. Fixed page selection in some places
9741 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9742 the registers name strings.
9743 4. Fixed "signed / unsigned compare" compiler warnings.
9744 5. The PIC port manages its own allocation of the general purpose
9745 registers, but makes no attempt to reuse them. As a result when
9746 compiling it soon runs out of general purpose registers. Some
9747 additional code was added to the files pcode.c and device.c to walk
9748 through the function call tree and rename the registers so that they
9758 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9759 genPlus() & genMinus() when the result is the same as left or right
9761 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9765 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9767 Made bitfield a distinct type from bit so that bitfields
9768 convert as per ANSI C and bits retain their traditional
9769 boolean style behaviour. Implemented bitfield support in
9777 * src/ds390/gen.c: bit v bitfield split
9778 * src/z80/gen.c: New support for bitfields
9779 * support/regression/tests/bitfields.c: reenabled z80,
9782 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9784 Rules 246.x, 247.x relate to bitfields, the others speed up
9785 access to xdata mapped I/O devices.
9787 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9789 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9791 Cleaned up genPackBits and genUnpackBits and added two helper
9792 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9793 for literal assignments in genPackBits (thanks to Frieder for
9799 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9801 Fixed bug #748310 (pointer to function type mishandled when the
9802 function name is omitted). Also fixed a SIGSEGV when a function
9803 attribute (reentrant, etc) is used on a non-function or on a
9804 function but misplaced before the parameter list.
9806 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9808 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

9834 omitted, the function will not automatically be given an entry
9835 in the interrupt vector table (similar to #pragma NOIV, but
9836 less syntacticly kludgy). The interrupt number is also now
9837 range checked. Also fixed a bug in the high order bit example

9905 * src/SDCCval.c (valDiv, valMod): fixed signdness
9906 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
9907 signedness of modulo, left and right shift

10355 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
10357 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
10358 it can be defined with CFLAGS when running configure
10359 * src/SDCCmain.c: fixed compiling + linking with object files
10361 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
10363 * configure.in: configure for pic16 port,
10364 added --disable-pic16-port
10365 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
10366 * src/SDCCmain.c: linkOptions is changed to set *,
10367 added if/endif conditional macros to remove options help
10368 messages from optionsTable when a port is not configured, added
10369 support for the PIc16 port in the ports table, when executing
10370 the compiler with no port specified on command line, a default
10371 port is selected with the new macro DEFAULT_PORT which is
10372 defined in port.h, in setDefaultOptions() linkOptions is removed
10373 from initialization assignment, since now it is a set,
10374 parseCmdLine uses setParseWithComma for linkOptions, in
10375 linkEdit() linkOptions are accessed with new function indexSet()
10376 which returns the i'th item of a set variable. See SDCCset.c, in
10377 linkEdit() when calling buildCmdLine(), added linkOptions as
10378 last argument. Now users can pass arguments to gplink via the
10379 -Wl option, main() uses pic16glue() to glue up pic16 programs
10380 * src/SDCCpeeph.c: various changes to support pic16
10381 * src/SDCCset.c: added function void *indexSet(set *, int) to

10391 * src/pic16/glue.c: commented out some error producing lines
10392 * src/pic16/main.c: __config directives are commented out to stop
10393 gpasm complaining and test the linkage with gplink, _linkCmd and
10394 _asmCmd changed to be more gplink and gpasm friendly
10395 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10396 produced an error when parsed, peep rule 12 is added to utilize
10397 movff, but it is commented out since the pCode does not support
10398 yet a command with 2 address arguments

11450 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
11451 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

11458 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
11460 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
11461 * src/mcs51/main.c: removed {bindir}{sep} from aslink
11463 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11465 * in /sdcc/as/mcs51/ changed these files in order to create an
11466 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11467 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11468 following files to include the previous two files: aslink.dsp,
11469 Makefile.aslink, Makefile.bcc, and Makefile.in.
11471 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11472 .adb instead of .cdb
11474 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11476 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11477 value from option --iram-size.
11479 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11481 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11484 2002-09-18 <wiml AT hhhh.org>
11486 * SDCClrange.h: exposed setFromRange() and setToRange()
11487 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11488 packRegsForAccUse() (bug 542397)
11489 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11490 multiple times and emitting the fetch operations more than once
11491 added aopGetUsesAcc() function to allow binary operators to
11492 fetch their operands in the correct order; made genMinus() emit
11493 compact code for X = LITERAL - Y
11495 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11496 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11497 sprintf() in line 1267.
11499 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11500 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11503 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11504 Changes to aslink (All the changes are marked with 'JCF'):
11506 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11509 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11510 area BSEG. Also moves, if possible, the DATA area down into the internal
11511 ram so more space is available.
11513 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11516 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11517 not bytes. Function summary() which creates a memory usage summary
11518 file with extension .mem. Reports of overlaping stack and small stack
11519 size. If the space for the stack is less than 16 bytes aslink trows a
11522 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11523 the 8051. Option 'y' for memory summary output file.
11525 Changes to sdcc (All the changes are marked with 'JCF'):
11527 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11529 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11530 overlaying area for it (uses RegBankUsed[4]).
11532 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11533 bank zero as used by default. By default aslink locates the stack
11534 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11535 the creation of the .mem file. Delegates the allocation of data area
11536 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11537 the begining of the stack area to aslink.
11539 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11540 glue() in SDCCglue.c creates an area for it.
11542 2002-09-03 Borut Razem <borut.razem AT siol.net>
11543 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11544 sdcc/src/pic/glue.c:
11545 introduced atexit() handler for teporay files removal in case of
11546 errors, assertions, ...
11548 2002-08-29 Borut Razem <borut.razem AT siol.net>
11549 * sdcc/support/cpp2/auto-host_vc_in.h:
11550 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11551 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11552 Maybe there is a similar problem with BORLANDC? It should be checked!
11554 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11555 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11556 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11557 was not executed, and the compiler (cl) launched a warning:
11558 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11560 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11561 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11563 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11564 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11566 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11567 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11568 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11569 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11570 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11571 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11572 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11573 - added Release configuration in VS projects
11574 - review of compiler an linker options
11575 - VC .exe files are generated in bin_vc directory, not to interfere
11576 with binaries generated from other projects (cygwin, mingw, bcc ...)
11578 * sdcc/src/yacc.dsp: added
11580 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11581 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11582 and insert the version number definitions from .version
11584 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11586 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11587 added - genarate auto-host.h using auto-host_vc_in.h as template
11590 removed from CVS, generated automatically
11592 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11593 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11595 2002-08-11 Borut Razem <borut.razem AT siol.net>
11596 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11598 2002-08-10 Borut Razem <borut.razem AT siol.net>
11599 * src/SDCCmain.c (main):
11600 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11601 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11602 The consequence was that some temporary files were not removed.
11605 unification of code in functions tempfilename() and tempfile():
11606 function tempnam() is defined in Visual Studio 6.0 and .NET

11814 Previous fix was not good. basic blocks that have "break" or "return" are
11815 not really partof a loop , but live ranges used in these blocks should
