1665 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1667 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1668 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1670 One basic decision: e.g. src/clean.mk includes further files. In order
1671 to make this work there are two solutions:
1672 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1673 run configure on them. This way they can use
1674 'include $(srcdir)/port-clean.mk'
1675 - always include clean.mk by the Makefile at the same level. To avoid
1676 that `make clean` tries to include and build Makefile.dep the
1677 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1678 implemented, because now even `make uninstall` doesn't create
1679 Makefile.in. clean.mk could be eliminated by pasting it in
1682 * debugger/mcs51/Makefile.in: build own objects from library sources
1683 (SLIB, SDCC) in current directory
1685 * configure, configure.in: renamed --disable-device-lib-build in
1686 --disable-device-lib; added --enable-doc, the required tools are
1687 searched by configure; added result message; the toolchain for the
1688 belonging ports are now only built, if the port is enabled.
1690 * support/regression/*: all output is written in directory gen, because
1691 the fwk and ports directories don't livet in the build tree using vpath
1693 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1694 --disable-device-lib, added --enable-doc, added section VPATH
1696 * sim/ucsim/configure.in,
1697 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1698 z80 are enabled by default
1700 2006-04-24 Raphael Neider <rneider AT web.de>
1702 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1703 to config word, "pic14_"-prefixed some extern functions
1704 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1705 config word has been found
1706 * src/pic/device.h: added prototypes
1707 * src/pic/pcode.c: added "pic14_"-prefix where needed
1708 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
1710 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
1712 (pic14emitRegularMap): ignore config words,
1713 (pic14createInterruptVect): moved generating __config directives away
1714 (picglue): have __config directives emitted
1716 2006-04-24 Borut Razem <borut.razem AT siol.net>

1723 registers that have not been assigned proper liveranges,
1724 fixes #1469504 and #1474602,
1725 (pCodeRegOptimizeRegUsage): fixed typo in comment
1727 2006-04-24 Borut Razem <borut.razem AT siol.net>
1729 * device/examples/main8051.c: deleted - it was removed from CVS
1730 24.mar.2000 and after that modified 18.feb.2001, so it reappered
1731 after the transition to Subversion
1732 * src/SDCCalloc.h: deleted - it was removed from CVS
1733 3.feb.2001 and after that modified 18.feb.2001, so it reappered

1995 * src/.version: increased version number to 2.5.5
1996 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1997 linking is done manually in pic16 port's _linkEdit,
1998 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1999 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
2000 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
2001 allocate asmop as AOP_ACC,
2002 (aopForRemat): added parameter 'bool result' in function declaration,
2003 (pic16_aopGet): return AOP_ACC when accessing WREG,

2016 call to allocReg, not by manually allocating a new one,
2017 (pic16_assignRegisters): now before going through the register
2018 allocating functions mark all registers as free. This eliminates some
2019 side effects resulting from peephole parser done earlier in the backbone

2082 'xinst' for initial support for Extended Instruction Support,
2083 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
2084 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
2085 port->fun_prefix anymore (may change later),
2086 (genFunction, genEndFunction): do not store/restore local registers for
2087 _main (this should take care the --main-return command line option in
2089 (genOr): removed some legacy pic-port instructions,
2090 * src/pic16/genarith.c (genAddLit): re-enabled old code because
2091 performing operations with SFR's causes data to be written more than
2092 once to each SFR. Perhaps SFRs should be handled in special cases...
2093 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
2095 * src/pic16/main.c (_process_pragma): stack bound checking did not take

2101 (commented out for reference), didn't account for some registers which
2102 were left marked 'not free' after a pointer operation. The change
2103 reduces register usage a lot in some cases

4372 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4374 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),

4378 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
4379 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
4380 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
4381 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
4382 always available in leading double underscore form. The C99 support is
4383 mostly missing, but it's a start.
4384 * support/regression/tests/bug-227710.c: fixed nonconforming use of
4385 reserved identifier "__data".
4387 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

4433 2005-03-20 Borut Razem <borut.razem AT siol.net>
4435 * support/scripts/inc2h.pl: WIN32 port

4463 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
4465 * device/lib/printf_large.c: removed inline assembly for portability and
4466 readability. Use printf_fast if speed or size are more important.
4467 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4468 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4470 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4472 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4473 prevent compiler warning
4475 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4477 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4478 moved to level 0 and declared as static. Also they are explicit
4479 placed in access bank. This was necessery because some times they
4480 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4481 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4482 optimizations. Currently only compare to unsigned char is implemented,
4483 * src/pic16/gen.c: added fReturnIdx array,
4484 * (struct resolvedIfx) is moved to gen.h and made public,
4485 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4486 * (aopForSym): added an optimization to directly store in stack of
4487 the operand of a SEND iCode,
4488 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4489 but as registers instead (AOP_REG) using the fReturnIdx array,
4490 * (pic16_freeAsmop): remove the freed register from the
4491 _G.sregsAlloc field,
4492 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4493 a compare of 'WREG',
4494 * (pic16_popGetTempRegCond): changed function prototype, now
4495 function takes also a bitVector argument v which holds the current
4496 set of registers that are allocated for stack access by aopForSym,
4497 registers allocated in aopForSym for accessing stack symbols are not
4498 any more part of the functions usedRegs field,
4499 * (genCall): some times aopOp is called for a stack variable to be
4500 send, aopForSym might perform the push, if this is true make sure
4501 that genCall doesn't push the variable twice by testing _G.resDirect,
4502 * (genFunction): changed testing for unspecified interrupt number
4503 from 256 to INTNO_UNSPEC,
4504 * modified selection scheme of frame pointer generation. Previously
4505 if function did use local registers a frame pointer was generated,
4506 now a frame pointer is generated only if function has arguments
4507 (that need PLUSW2 register access), or has stack arguments, or the
4508 compiler is not instructed to omit the frame pointer,
4509 * (genEndFunction): before restoring local registers that were saved
4510 in the function preamble, also restore the registers that *might*
4511 have been allocated for stack access,
4512 * (genRet): removed some old comments,
4513 * (genCmp, the active (RN's) version): added a call to the
4514 pic16_genCmp_special function to perform the compare with a more
4515 robust and optimized way,
4516 * (genInline): a feature has been added in inline code generation,
4517 which allows a wildcard variable substitution when writing inline
4518 assembly. Code is incomplete and experimental therefore undocumented,
4519 * (genCast): changed order of aopOp for result and right to allow
4520 aopForSym to directly load the result if possible,
4521 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4522 perform an optimized compare on some selected special occasions,
4523 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4524 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4525 generate an IVT any more,
4526 * src/pic16/main.c (pic16_optionsTable): added command line option
4528 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4529 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4531 * src/pic16/NOTES: Raphael Neider added in list of active developers
4532 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4533 jumptable_end to prevent bug #,
4534 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4535 inCond and outCond fields,
4536 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4537 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4538 turn off register spilling,
4539 * (packRegsForOneUse): synced with other ports' versions although it
4540 is not used currently,
4541 * (pic16_packRegisters): added an optimization while reading
4542 structure bitfields, some registers may be saved (malloc code is
4543 decreased by 80 bytes)
4545 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4547 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4548 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4549 this can be optimized more?
4551 2005-03-10 Raphael Neider <rneider AT web.de>
4553 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4554 genNearPointerGet): (hopefully) fixed access to bitfields via
4555 pointers (p->bitN = x; and x = p->bitN; failed)
4557 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

4598 2005-02-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4600 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
4601 to keep the correct label reference count when adding/removing references
4602 to labels. A peephole file using this is appended to patch #1144962.

4734 * src/pic16/main.c (_process_pragma): fixed another malloc bug
4735 (sizeof(sectNames) changed to sizeof(sectName))
4736 Both patches fix segfaults under MinGW.
4738 2005-01-23 Raphael Neider <rneider AT web.de>

4741 Safe_[mc]?alloc()'ed variables
4742 * src/pic16/gen.c (pic16_aopOp,pic16_popGet): added handling
4743 of (byte sized) temporaries (assign them to WREG for now)
4744 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
4745 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
4746 this might fix SIGSEGVs on MinGW...
4747 * src/SDCCopt.c (killDeadCode): restored original behaviour
4748 (volatile operands might get thrown away though)

5176 comparisons, and supports quoted literals
5177 * src/mcs51/peeph.def: restored rule 177.d with an extra condition
5179 2004-12-02 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

5187 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5189 Adding support for replacing ljmps with sjmps in jumptables
5190 generated for switch statements. For now you need to set the
5191 environment variable SDCC_SJMP_JUMPTABLE to enable this.
5192 Now 4 algorithms for mcs51 jumptable generation are used:
5193 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
5194 addresses loaded pc-relative for up to 112 cases and stack-pushing
5195 target addresses loaded with offset from dptr for up to 256 cases.
5197 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
5198 * src/mcs51/main.c: adapted constants for switch table generation
5199 * src/mcs51/peeph.def: added 260.x for replacing ljmp with sjmp

5221 Large cummulative patch for pic16 port.
5222 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
5223 to call when a stack overflow occurs,
5224 * (malloc.h): added CVS Id tag,
5225 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
5227 * added libc directory. The current version of LibC contains string
5228 functions, ctype functions and macros and some functions of the
5229 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
5230 be extensively tested in the future. Standard disclaimer here.
5231 Library is not automatically build yet. But one can build it by
5232 invoking 'make' inside the libc directory.
5233 * added ADC library under libio. Preliminary version yet.
5235 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
5236 * src/pic16/gen.c (aopForRemat): asmop size is filled by
5237 aopForRemat() now and not by pic16_aopOp(),
5238 * (pic16_popGetTempReg): removed warning messgae when allocating
5239 temporary registers, its a buggy feature and will be removed,
5240 * (pic16_popGet): set register instance field in AOP_CRY,
5241 * (pic16_outBitC): fixed for results in size greater than 1,
5242 * (genUminusFloat): fixed for pic16, ported code from mcs51,
5243 * (pic16_storeForReturn): optimized return of 0,
5244 * (genCmp): experimental code for new genCmp which uses PIC18's
5245 special compare&skip instructions. Initial tests fail some times
5246 with variables grater than 1 byte in size, so new code is disabled,
5247 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5249 * (genCast): began a fix to optimize the casting of a bit to another
5250 bit, now assigning a bitfield to another bitfield will fail, sorry,
5251 * src/pic16/main.c: disabled the use of lr-support feature,
5252 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
5253 * added some function prototypes, added function _debugf prototype,
5254 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
5255 bits with offset (case PO_GPR_BIT),
5256 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
5258 * (isBankInstruction): modified to return 0 for no banking instruction,
5259 and 1 for banking instruction,
5260 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
5261 caused stop processing pCodes after a inline assembly block,
5262 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
5263 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
5264 registers when it shouldn't,
5265 * src/pic16/ralloc.c (allocReg): add preliminary support for
5266 supporting a limited set of temporary registers,
5268 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5270 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
5271 genDataPointerSet): ensure assignments always copy in MSB to LSB
5273 (loadRegFromAop): recognize CLRH optimization,
5274 (genFunction): optimize RECEIVE iCodes in reentrant functions
5276 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5278 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
5279 --out-fmt-s19 turning into --out-fmt-elf if s19 was already

5288 * device/lib/_gptrgetc.c (_gptrgetc),
5289 * device/lib/_gptrput.c (_gptrput): _naked allows to use ret
5290 instead of sjmp to ret
5291 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
5292 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
5294 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

8276 loaded with the linker search paths (-L arguments) and the libraries
8277 to be linked with the current source (-l arguments). Changes
8278 currently will affect only the pic16 port.
8279 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8280 include path the port specific paths and port specific libraries,
8281 * gplink command now contains the $3 argument,
8282 * src/pic16/device.h,
8283 * src/pic16/device.c,: structure PIC_device is made public and
8284 renamed to PIC16_device, the same for variable Pics which is renamed
8285 to Pics16. Updated all references to them.
8286 * src/pic16/glue.c (pic16glue): corrected bug with code
8287 initialization which bypassed the variable initializations block.
8289 * device/lib/pic16/Makefile.rules: removed --penable-stack from
8290 COMPILE_FLAGS and added the --nostdinc option
8292 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8294 * device/include/mc68hc908jb8.h: Register defs for another member
8295 of the hc08 family. Contributed by Bjorn Bringert - thanks!
8297 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
8299 Documenting changes from previous commits.
8300 * configure.in (version 1.56),
8301 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8302 when generating output files to configure the pic16 library,
8303 but now I've commented it out, since gputils aren't installed in the
8304 SF compile farm, so library won't compile
8306 * device/lib/Makefile.in (version 1.56): initially I've added in
8307 target 'all' the prerequestive 'model-pic16' so it compiled the
8308 pic16 library, but now I've commented it out for the same reasons
8310 * added targets 'model-pic16' and 'objects-pic16' to compile the
8312 * added target 'port-specific-objects-pic16' to handle the
8313 generated libraries and copy them into the build/ directory
8314 * added target 'clean-intermediate-pic16' to clean intermediate
8315 files into pic16 directory
8316 * in target 'installdirs' added line to create directory pic16 in
8317 the installation path
8319 * device/include/Makefile.in (version 1.11): in target 'install'
8320 added lines to copy all header files to installation path,
8321 * in target 'installdirs' added line create directory for pic16
8322 headers in the installation path

8337 * src/z80/main.c (_parseOptions): fixed the portmode= command line
8338 option so that it actually works. Made it specific to the z80, since
8339 the gbz80 doesn't have these kinds of I/O ports.
8341 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8343 * device/include/z180.h,

8356 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8358 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
8359 changed interrupt vector table generation to only emit declared vectors.
8360 * device/include/Makefile.in: added missing backslash
8361 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)

8365 Mainly changes to support compilation of the device libraries
8366 * src/pic16/device.c: stack is allocated via symbol and not
8367 via literal number. The symbol is placed in the corresponding
8368 position of the data ram
8369 * (pic16_dump_section): relocatable and absolute uninitialized
8370 data are now emitted in sorted order to reduce section naming,
8371 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
8372 weren't marked as being in the access bank,
8374 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
8376 Added portion of GNU PIC Library under the directory
8377 device/include/pic16 and device/lib/pic16. These files
8378 contain the declarations of SFRs for the PIC18Fxx2 devices.
8379 The directory is initialized via configure from toplevel.
8381 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
8383 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
8384 the spilllocations to be compared correctly
8386 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
8388 * src/SDCCast.c (decorateType): fixed bug introduced today
8390 2004-01-12 Borut Razem <borut.razem AT siol.net>

8408 * doc/sdccman.lyx: Moved and added some sections, small changes
8409 all over. Telling LaTeX to be less strict with word spacing
8410 to better keep the right margin. Changed some notes about
8411 maintainance of the ports in section 3.2.1 - is it OK like this?
8413 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

8450 UPPER for immediate operands,
8451 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
8453 * src/pic16/peeph.def: all peepholes with movff are commented out,
8454 because there is a problem in the pcode peep optimizer,
8455 * src/pic16/ralloc.c: the register allocator can now reuse local

8457 * src/pic16/ralloc.h: added flag isLocal in structure regs,
8459 Added file src/pic16/NOTES with information about program writing on
8460 the current port version.

8492 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8495 * src/z80/main.c: added missed needLinkerScript flags (more than
8496 one port structure defined in these file)
8497 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

8513 needLinkerScript flag
8515 * src/pic16/gen.c (genAddrOf): fixed bug #863624
8516 * src/pic/glue.c: added variable udata_section_name to
8517 override default uninitialized data segment definition for
8518 devices only with SHAREBANK memory (reported from Erik Epetrich)
8519 * (pic14emitOverlay): modified to emit a commented overlay segment
8520 directive when no overlay data exist
8521 * (picglue): modified to emit uninitialized data segment
8522 according to udata_section_name

8528 * src/pic16/main.c: added $l in _asmCmd, changed extension for
8529 object file from '.rel' to '.o' in port->linker structure,
8530 changed size of fptr from 2 to 3 in port structure
8532 2004-01-07 Borut Razem <borut.razem AT siol.net>
8534 * support/scripts/sdcc.nsi: update PATH
8535 * support/scripts/sdcc.ico: craeted
8537 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>

8548 include information about variables allocated to the overlay
8551 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8553 * as/mcs51/lkmain.c: Help about -Y option

8565 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8567 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
8568 (default behaviour).
8570 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8572 A python script to validate compiler diagnostic messages. It can be
8573 used to verify that sdcc complains about bad c source code and
8574 gives a good location of the error.
8575 * support/valdiag/Makefile,
8576 * support/valdiag/valdiag.py,
8577 * support/valdiag/tests/*
8579 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8592 * src/common.h: added ifndef/define/endif macros
8593 around the header file.
8594 Bug reported from Jesus Calvino-Fraga
8596 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8598 * sdcc.spec: updated
8599 * device/include/Makefile.in: don't install CVS directories
8600 * device/lib/Makefile.in: added removal of CVS directories after install
8601 * doc/Makefile: fixed install, added local_icons
8602 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8603 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8604 * src/ds390/gen.c (genRightShift): fixed bug #870788
8605 * src/SDCCast.c (decorateType): fixed bug #870781
8607 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8609 PIC16 port related changes:
8610 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8611 added variable stackPos,
8613 * gen.c: genCall, assignResultValue: added support for
8614 pushing/retrieving function parameters to/from stack,
8615 genFunction,genEndFunction: setup stack frame for the
8617 genAddrOf: will be changed according to bug 863624
8619 * added files genutils.c and genutils.h which contain gen*
8620 debugged and optimised functions extracted from gen.c
8622 * glue.c: added variable 'externs' which holds extern symbols,
8623 pic16emitRegularMap: is modified to properly handle relocatable
8624 symbols under the new scheme,
8625 pic16createInterruptVect: is modified
8626 pic16printPublics: is modified to emit 'global' assembler directives,
8627 added pic16_printExterns to print extern symbols,
8628 pic16glue: initializes stack/frame pointer in the beginning of
8629 the assembly output. Temporary hack, will be corrected later,
8630 because gplink yet does not support stack and SDCC does not
8631 yet support a type of crt0.o object to create the final binary.
8633 * Removed many lines that contain 8051 legacy code.
8634 * The code is finally placed under a 'code' directive.
8635 * Added port specific options.
8637 * _process_pragma: simplified since now we do not need *special*
8638 include file to define SFR registers. But a separate header
8639 will be needed. This will be developed later.
8640 * _pic16_parseOptions: added, parses port specific options:
8641 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8642 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8643 --preplace-udata-with=
8645 * _pic16_setDefaultOptions: modified to initialize section names,
8646 but hack is temporarly out of order since it needs improvement.
8647 * _pic16_genAssemblerPreamble: configuration words are emitted by
8648 their address instead of their name. This part is incomplete and
8649 supports only the 18Fxx2 devices. Other devices will emit an error
8650 during assembly since they do not contain the same set of config
8652 * _pic16_genIVT: is modified,
8654 * pcode.c: added definitions for some hardware registers that are needed
8656 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8657 All PCI entries are updated. Now LFSR is supported.
8658 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8659 * added pic16_newpCodeOpLit2 to support instructions with
8660 two literal arguments
8661 * pic16_pCode2str: corrected code that emits assembler instructions
8662 with two literal operands and those that have an access bit modifier
8663 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8664 this fixes a bug which caused some labels to be lost, when an
8665 assembler directive was added, i.e. banksel,
8666 * pic16_FixRegisterBanking: improved logic that causes the insertion
8668 * InlineFunction: functions that are called once, are not any more
8669 inlined. This can be a port option in the future,
8671 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8673 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8674 hold the corresponding uninitialized symbols,
8675 * pic16_allocProcessorRegister: registers have explicit marked the
8677 * pic16_allocInternalRegister: registers are explicit marked as
8679 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8680 processing list, so bit registers were lost,
8683 * ralloc.h: added field 'accessBank' and original symbol operand
8684 in register definition,
8685 * removed the field isMapped from register definition,
8687 ** Several functions have been removed from various sources:
8688 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8689 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8690 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8691 pic16_assignRelocatableRegisters
8693 ** others have been introduced:
8694 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8695 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8697 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8699 * support/scripts/inc2h.pl: changed definition of BIT_AT
8700 to emit 'sbit at' instead of 'bit at'. This was a request.
8702 PIC16 port related preliminary changes:
8703 * gen.c: prefixed function popRegFromString with
8704 pic16_ and all references to it corrected
8705 * pcode.c: all pic16_pc_* hardware registers prefixed
8706 with underscore (_),
8707 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8708 * ralloc.c: newReg(): when register is REG_SFR then
8709 set address to rIdx,
8710 pic16_allocProcessorRegister(): marks register wasUsed=0
8711 pic16_writeUsedRegs(): added a call to assign processor
8712 registers via pic16_assignFixedRegisters
8714 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8716 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8717 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8718 variables in unused register banks. Also the SSEG is placed
8719 wherever there is enough space for it, and IDATA can be anywhere
8720 in internal RAM. For now compile using -Wl-Y[stack_size].
8721 The mem file is different for this option as well, since it
8722 makes no sense of talking about DSEG lenght.
8724 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8726 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8727 in certain cases, e.g. when ROM assignment, patch provided
8728 from Albert den Haan.
8730 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

9773 A few small changes that speed up the peephole optimizer.
9777 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9779 Try to make the peephole optimizer smarter by maintaining
9780 an association between the assembly source code and the
9781 iCodes that originated them. Put this information to use
9782 with a new peephole rule condition "notVolatile" so that
9783 the rules can be aggressive yet still safe.
9788 * src/mcs51/peeph.def
9790 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9794 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9795 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9796 if the left or right operand symbols have the accuse flag set.
9798 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9800 Changed the type of the result of the ! (NOT) operator to char;
9801 previously it returned the same type as the source. This allows
9802 us to eliminate all the genFloatNot functions (all of its target
9803 implementations were very buggy) since !float can use the same
9806 * src/SDCCicode.c (ast2iCode): ! returns char
9807 * src/mcs51/gen.c (genNot, genNotFloat),
9808 * src/ds390/gen.c (genNot, genNotFloat),
9809 * src/z80/gen.c (genNot, genNotFloat),
9810 * src/pic/gen.c (genNot, genNotFloat),

9815 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9816 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9817 during interrupts. Ensure WSAVE is located at a shared bank address.
9818 2. Fixed page selection in some places
9819 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9820 the registers name strings.
9821 4. Fixed "signed / unsigned compare" compiler warnings.
9822 5. The PIC port manages its own allocation of the general purpose
9823 registers, but makes no attempt to reuse them. As a result when
9824 compiling it soon runs out of general purpose registers. Some
9825 additional code was added to the files pcode.c and device.c to walk
9826 through the function call tree and rename the registers so that they
9836 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9837 genPlus() & genMinus() when the result is the same as left or right
9839 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9843 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9845 Made bitfield a distinct type from bit so that bitfields
9846 convert as per ANSI C and bits retain their traditional
9847 boolean style behaviour. Implemented bitfield support in
9855 * src/ds390/gen.c: bit v bitfield split
9856 * src/z80/gen.c: New support for bitfields
9857 * support/regression/tests/bitfields.c: reenabled z80,
9860 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9862 Rules 246.x, 247.x relate to bitfields, the others speed up
9863 access to xdata mapped I/O devices.
9865 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9867 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9869 Cleaned up genPackBits and genUnpackBits and added two helper
9870 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9871 for literal assignments in genPackBits (thanks to Frieder for
9877 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9879 Fixed bug #748310 (pointer to function type mishandled when the
9880 function name is omitted). Also fixed a SIGSEGV when a function
9881 attribute (reentrant, etc) is used on a non-function or on a
9882 function but misplaced before the parameter list.
9884 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9886 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

9909 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9911 Made the constant following the "interrupt" keyword optional. If
9912 omitted, the function will not automatically be given an entry
9913 in the interrupt vector table (similar to #pragma NOIV, but
9914 less syntacticly kludgy). The interrupt number is also now
9915 range checked. Also fixed a bug in the high order bit example

9929 * src/SDCCicode.c (operandOperation): rewritten some ops
9930 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
9931 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9933 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9934 be re-activated by defining REDUCE_LITERALS)

9936 unsigned, but are signed by default
9937 * src/SDCCval.c (constVal): rearranged
9938 * src/SDCCval.c (valMod): preliminary fix
9939 * src/SDCCval.c (valCastLiteral): use TYPE_* types

10391 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
10392 the regression tests I'm not brave enough to enable 245.b, 245.c
10393 * doc/sdccman.lyx: added latex preamble for hyperref package.
10394 Using pdflatex this will give you a hyperlinked pdf file with
10395 bookmarks. (prepend '%' before /usepackage if this breaks something)

10445 added if/endif conditional macros to remove options help
10446 messages from optionsTable when a port is not configured, added
10447 support for the PIc16 port in the ports table, when executing
10448 the compiler with no port specified on command line, a default
10449 port is selected with the new macro DEFAULT_PORT which is
10450 defined in port.h, in setDefaultOptions() linkOptions is removed
10451 from initialization assignment, since now it is a set,
10452 parseCmdLine uses setParseWithComma for linkOptions, in
10453 linkEdit() linkOptions are accessed with new function indexSet()
10454 which returns the i'th item of a set variable. See SDCCset.c, in
10455 linkEdit() when calling buildCmdLine(), added linkOptions as
10456 last argument. Now users can pass arguments to gplink via the
10457 -Wl option, main() uses pic16glue() to glue up pic16 programs

10469 * src/pic16/glue.c: commented out some error producing lines
10470 * src/pic16/main.c: __config directives are commented out to stop
10471 gpasm complaining and test the linkage with gplink, _linkCmd and
10472 _asmCmd changed to be more gplink and gpasm friendly
10473 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10474 produced an error when parsed, peep rule 12 is added to utilize
10475 movff, but it is commented out since the pCode does not support
10476 yet a command with 2 address arguments
10478 2003-05-18 <johan AT balder>
10480 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

11605 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11607 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11608 overlaying area for it (uses RegBankUsed[4]).
11610 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11611 bank zero as used by default. By default aslink locates the stack
11612 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11613 the creation of the .mem file. Delegates the allocation of data area
11614 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11615 the begining of the stack area to aslink.
11617 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11618 glue() in SDCCglue.c creates an area for it.
11620 2002-09-03 Borut Razem <borut.razem AT siol.net>
11621 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11622 sdcc/src/pic/glue.c:
11623 introduced atexit() handler for teporay files removal in case of
11624 errors, assertions, ...
11626 2002-08-29 Borut Razem <borut.razem AT siol.net>
11627 * sdcc/support/cpp2/auto-host_vc_in.h:
11628 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11629 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11630 Maybe there is a similar problem with BORLANDC? It should be checked!
11632 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11633 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11634 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11635 was not executed, and the compiler (cl) launched a warning:
11636 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11638 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11639 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11641 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11642 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11644 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11645 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11646 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11647 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11648 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11649 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11650 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11651 - added Release configuration in VS projects
11652 - review of compiler an linker options
11653 - VC .exe files are generated in bin_vc directory, not to interfere
11654 with binaries generated from other projects (cygwin, mingw, bcc ...)
11656 * sdcc/src/yacc.dsp: added
11658 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11659 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11660 and insert the version number definitions from .version
11662 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11664 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11665 added - genarate auto-host.h using auto-host_vc_in.h as template
11668 removed from CVS, generated automatically
11670 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11671 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11673 2002-08-11 Borut Razem <borut.razem AT siol.net>
11674 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11676 2002-08-10 Borut Razem <borut.razem AT siol.net>
11677 * src/SDCCmain.c (main):
11678 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11679 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11680 The consequence was that some temporary files were not removed.
11683 unification of code in functions tempfilename() and tempfile():
11684 function tempnam() is defined in Visual Studio 6.0 and .NET
11686 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11688 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11689 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11690 - removed compiler command line option /WX: Treats all warnings as errors
11691 - update a list of source files, included into the project
11693 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11694 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11695 changed project type to Generic Project so that can be correcly converted to VS.NET project
11697 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11699 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11701 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11703 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11704 added return 0 statements after assert() to make compiler happy
11706 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11707 added newline in the def file to keep MSC compiler satisfied
11709 * sdcc/src/z80/gen.c:
11710 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11711 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11712 - solved MSC error in function aopDump()
11714 * sdcc_vc.h: define PREFIX as "\\sdcc"
11716 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
11717 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

11765 Added -p option. Allows port dependent processor to be specified.
11768 Initialized the new field char *Processor field to NULL in all ports
11771 Compiler generated registers for interrupt context saving
11772 were not getting allocated.
11774 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
11777 Fixed left shift. Will promote the left side of a left shift
11778 if a) left shifting more than size of operand or b) when assigned
11779 to something size > size of left side

11889 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
11891 * sdcc/src/SDCCloop.c:
11892 Previous fix was not good. basic blocks that have "break" or "return" are
11893 not really partof a loop , but live ranges used in these blocks should
11894 be live thru the entire loop, so set partOfLoop but don't add them to
11897 2002-02-21 <johan AT FRIJA>
11899 * src/SDCCcse.c: fixed bug #514308
11901 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
