1658 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1660 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1661 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1663 One basic decision: e.g. src/clean.mk includes further files. In order
1664 to make this work there are two solutions:
1665 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1666 run configure on them. This way they can use
1667 'include $(srcdir)/port-clean.mk'
1668 - always include clean.mk by the Makefile at the same level. To avoid
1669 that `make clean` tries to include and build Makefile.dep the
1670 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1671 implemented, because now even `make uninstall` doesn't create
1672 Makefile.in. clean.mk could be eliminated by pasting it in
1675 * debugger/mcs51/Makefile.in: build own objects from library sources
1676 (SLIB, SDCC) in current directory
1678 * configure, configure.in: renamed --disable-device-lib-build in
1679 --disable-device-lib; added --enable-doc, the required tools are
1680 searched by configure; added result message; the toolchain for the
1681 belonging ports are now only built, if the port is enabled.
1683 * support/regression/*: all output is written in directory gen, because
1684 the fwk and ports directories don't livet in the build tree using vpath
1686 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1687 --disable-device-lib, added --enable-doc, added section VPATH
1689 * sim/ucsim/configure.in,
1690 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1691 z80 are enabled by default
1693 2006-04-24 Raphael Neider <rneider AT web.de>
1695 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1696 to config word, "pic14_"-prefixed some extern functions
1697 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1698 config word has been found
1699 * src/pic/device.h: added prototypes
1700 * src/pic/pcode.c: added "pic14_"-prefix where needed
1701 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
1703 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

1706 (pic14createInterruptVect): moved generating __config directives away

1716 registers that have not been assigned proper liveranges,
1717 fixes #1469504 and #1474602,
1718 (pCodeRegOptimizeRegUsage): fixed typo in comment
1720 2006-04-24 Borut Razem <borut.razem AT siol.net>
1722 * device/examples/main8051.c: deleted - it was removed from CVS
1723 24.mar.2000 and after that modified 18.feb.2001, so it reappered
1724 after the transition to Subversion
1725 * src/SDCCalloc.h: deleted - it was removed from CVS
1726 3.feb.2001 and after that modified 18.feb.2001, so it reappered

1988 * src/.version: increased version number to 2.5.5
1989 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1990 linking is done manually in pic16 port's _linkEdit,
1991 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1992 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1993 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1994 allocate asmop as AOP_ACC,
1995 (aopForRemat): added parameter 'bool result' in function declaration,
1996 (pic16_aopGet): return AOP_ACC when accessing WREG,

2008 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
2009 call to allocReg, not by manually allocating a new one,
2010 (pic16_assignRegisters): now before going through the register
2011 allocating functions mark all registers as free. This eliminates some
2012 side effects resulting from peephole parser done earlier in the backbone

2075 'xinst' for initial support for Extended Instruction Support,
2076 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
2077 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
2078 port->fun_prefix anymore (may change later),
2079 (genFunction, genEndFunction): do not store/restore local registers for
2080 _main (this should take care the --main-return command line option in
2082 (genOr): removed some legacy pic-port instructions,
2083 * src/pic16/genarith.c (genAddLit): re-enabled old code because
2084 performing operations with SFR's causes data to be written more than
2085 once to each SFR. Perhaps SFRs should be handled in special cases...
2086 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
2088 * src/pic16/main.c (_process_pragma): stack bound checking did not take

2094 (commented out for reference), didn't account for some registers which
2095 were left marked 'not free' after a pointer operation. The change
2096 reduces register usage a lot in some cases

4363 on rIfx (genCmp was broken)
4365 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4367 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
4368 * src/z80/main.c (_keywords[]),
4369 * src/SDCCglobal.h (struct options),
4371 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
4372 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
4373 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
4374 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
4375 always available in leading double underscore form. The C99 support is
4376 mostly missing, but it's a start.
4377 * support/regression/tests/bug-227710.c: fixed nonconforming use of
4378 reserved identifier "__data".
4380 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>
4382 * src/mcs51/peeph.def: fixed bug 1170013

4424 immedDom() returning wrong block; probably fixes bug #1160833)
4426 2005-03-20 Borut Razem <borut.razem AT siol.net>
4428 * support/scripts/inc2h.pl: WIN32 port

4432 * device/lib/makefile.in: added abs.c and labs.c
4434 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
4436 * device/include/stdint.h: added
4437 * device/lib/abs.c: added

4456 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
4458 * device/lib/printf_large.c: removed inline assembly for portability and
4459 readability. Use printf_fast if speed or size are more important.
4460 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4461 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4463 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4465 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4466 prevent compiler warning
4468 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4470 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4471 moved to level 0 and declared as static. Also they are explicit
4472 placed in access bank. This was necessery because some times they
4473 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4474 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4475 optimizations. Currently only compare to unsigned char is implemented,
4476 * src/pic16/gen.c: added fReturnIdx array,
4477 * (struct resolvedIfx) is moved to gen.h and made public,
4478 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4479 * (aopForSym): added an optimization to directly store in stack of
4480 the operand of a SEND iCode,
4481 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4482 but as registers instead (AOP_REG) using the fReturnIdx array,
4483 * (pic16_freeAsmop): remove the freed register from the
4484 _G.sregsAlloc field,
4485 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4486 a compare of 'WREG',
4487 * (pic16_popGetTempRegCond): changed function prototype, now
4488 function takes also a bitVector argument v which holds the current
4489 set of registers that are allocated for stack access by aopForSym,
4490 registers allocated in aopForSym for accessing stack symbols are not
4491 any more part of the functions usedRegs field,
4492 * (genCall): some times aopOp is called for a stack variable to be
4493 send, aopForSym might perform the push, if this is true make sure
4494 that genCall doesn't push the variable twice by testing _G.resDirect,
4495 * (genFunction): changed testing for unspecified interrupt number
4496 from 256 to INTNO_UNSPEC,
4497 * modified selection scheme of frame pointer generation. Previously
4498 if function did use local registers a frame pointer was generated,
4499 now a frame pointer is generated only if function has arguments
4500 (that need PLUSW2 register access), or has stack arguments, or the
4501 compiler is not instructed to omit the frame pointer,
4502 * (genEndFunction): before restoring local registers that were saved
4503 in the function preamble, also restore the registers that *might*
4504 have been allocated for stack access,
4505 * (genRet): removed some old comments,
4506 * (genCmp, the active (RN's) version): added a call to the
4507 pic16_genCmp_special function to perform the compare with a more
4508 robust and optimized way,
4509 * (genInline): a feature has been added in inline code generation,
4510 which allows a wildcard variable substitution when writing inline
4511 assembly. Code is incomplete and experimental therefore undocumented,
4512 * (genCast): changed order of aopOp for result and right to allow
4513 aopForSym to directly load the result if possible,
4514 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4515 perform an optimized compare on some selected special occasions,
4516 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4517 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4518 generate an IVT any more,
4519 * src/pic16/main.c (pic16_optionsTable): added command line option
4521 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4522 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4524 * src/pic16/NOTES: Raphael Neider added in list of active developers
4525 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4526 jumptable_end to prevent bug #,
4527 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4528 inCond and outCond fields,
4529 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4530 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4531 turn off register spilling,
4532 * (packRegsForOneUse): synced with other ports' versions although it
4533 is not used currently,
4534 * (pic16_packRegisters): added an optimization while reading
4535 structure bitfields, some registers may be saved (malloc code is
4536 decreased by 80 bytes)
4538 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4540 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4541 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4542 this can be optimized more?
4544 2005-03-10 Raphael Neider <rneider AT web.de>
4546 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4547 genNearPointerGet): (hopefully) fixed access to bitfields via
4548 pointers (p->bitN = x; and x = p->bitN; failed)
4550 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
4552 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

4593 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
4594 to keep the correct label reference count when adding/removing references
4595 to labels. A peephole file using this is appended to patch #1144962.

4727 * src/pic16/main.c (_process_pragma): fixed another malloc bug
4728 (sizeof(sectNames) changed to sizeof(sectName))
4729 Both patches fix segfaults under MinGW.
4731 2005-01-23 Raphael Neider <rneider AT web.de>

4734 Safe_[mc]?alloc()'ed variables
4735 * src/pic16/gen.c (pic16_aopOp,pic16_popGet): added handling
4736 of (byte sized) temporaries (assign them to WREG for now)
4737 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
4738 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
4739 this might fix SIGSEGVs on MinGW...
4740 * src/SDCCopt.c (killDeadCode): restored original behaviour
4741 (volatile operands might get thrown away though)
4743 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>
4745 * src/pic16/gen.c: fixed bug #1106975,

5180 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5182 Adding support for replacing ljmps with sjmps in jumptables
5183 generated for switch statements. For now you need to set the
5184 environment variable SDCC_SJMP_JUMPTABLE to enable this.
5185 Now 4 algorithms for mcs51 jumptable generation are used:
5186 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
5187 addresses loaded pc-relative for up to 112 cases and stack-pushing
5188 target addresses loaded with offset from dptr for up to 256 cases.
5190 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
5191 * src/mcs51/main.c: adapted constants for switch table generation
5192 * src/mcs51/peeph.def: added 260.x for replacing ljmp with sjmp

5212 2004-11-24 Vangelis Rokas <vrokas AT otenet.gr>
5214 Large cummulative patch for pic16 port.
5215 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
5216 to call when a stack overflow occurs,
5217 * (malloc.h): added CVS Id tag,
5218 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
5220 * added libc directory. The current version of LibC contains string
5221 functions, ctype functions and macros and some functions of the
5222 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
5223 be extensively tested in the future. Standard disclaimer here.
5224 Library is not automatically build yet. But one can build it by
5225 invoking 'make' inside the libc directory.
5226 * added ADC library under libio. Preliminary version yet.
5228 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
5229 * src/pic16/gen.c (aopForRemat): asmop size is filled by
5230 aopForRemat() now and not by pic16_aopOp(),
5231 * (pic16_popGetTempReg): removed warning messgae when allocating
5232 temporary registers, its a buggy feature and will be removed,
5233 * (pic16_popGet): set register instance field in AOP_CRY,
5234 * (pic16_outBitC): fixed for results in size greater than 1,
5235 * (genUminusFloat): fixed for pic16, ported code from mcs51,
5236 * (pic16_storeForReturn): optimized return of 0,
5237 * (genCmp): experimental code for new genCmp which uses PIC18's
5238 special compare&skip instructions. Initial tests fail some times
5239 with variables grater than 1 byte in size, so new code is disabled,
5240 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5242 * (genCast): began a fix to optimize the casting of a bit to another
5243 bit, now assigning a bitfield to another bitfield will fail, sorry,
5244 * src/pic16/main.c: disabled the use of lr-support feature,
5245 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
5246 * added some function prototypes, added function _debugf prototype,
5247 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
5248 bits with offset (case PO_GPR_BIT),
5249 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
5251 * (isBankInstruction): modified to return 0 for no banking instruction,
5252 and 1 for banking instruction,
5253 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
5254 caused stop processing pCodes after a inline assembly block,
5255 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
5256 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
5257 registers when it shouldn't,
5258 * src/pic16/ralloc.c (allocReg): add preliminary support for
5259 supporting a limited set of temporary registers,
5261 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5263 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
5264 genDataPointerSet): ensure assignments always copy in MSB to LSB
5266 (loadRegFromAop): recognize CLRH optimization,
5267 (genFunction): optimize RECEIVE iCodes in reentrant functions
5269 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5271 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
5272 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
5274 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

5281 * device/lib/_gptrgetc.c (_gptrgetc),
5282 * device/lib/_gptrput.c (_gptrput): _naked allows to use ret
5283 instead of sjmp to ret
5284 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
5285 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
5287 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

8269 loaded with the linker search paths (-L arguments) and the libraries
8270 to be linked with the current source (-l arguments). Changes
8271 currently will affect only the pic16 port.
8272 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8273 include path the port specific paths and port specific libraries,
8274 * gplink command now contains the $3 argument,
8275 * src/pic16/device.h,
8276 * src/pic16/device.c,: structure PIC_device is made public and
8277 renamed to PIC16_device, the same for variable Pics which is renamed
8278 to Pics16. Updated all references to them.
8279 * src/pic16/glue.c (pic16glue): corrected bug with code
8280 initialization which bypassed the variable initializations block.
8282 * device/lib/pic16/Makefile.rules: removed --penable-stack from
8283 COMPILE_FLAGS and added the --nostdinc option
8285 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8287 * device/include/mc68hc908jb8.h: Register defs for another member
8288 of the hc08 family. Contributed by Bjorn Bringert - thanks!
8290 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
8292 Documenting changes from previous commits.
8293 * configure.in (version 1.56),
8294 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8295 when generating output files to configure the pic16 library,
8296 but now I've commented it out, since gputils aren't installed in the
8297 SF compile farm, so library won't compile
8299 * device/lib/Makefile.in (version 1.56): initially I've added in
8300 target 'all' the prerequestive 'model-pic16' so it compiled the
8301 pic16 library, but now I've commented it out for the same reasons
8303 * added targets 'model-pic16' and 'objects-pic16' to compile the
8305 * added target 'port-specific-objects-pic16' to handle the
8306 generated libraries and copy them into the build/ directory
8307 * added target 'clean-intermediate-pic16' to clean intermediate
8308 files into pic16 directory
8309 * in target 'installdirs' added line to create directory pic16 in
8310 the installation path
8312 * device/include/Makefile.in (version 1.11): in target 'install'
8313 added lines to copy all header files to installation path,
8314 * in target 'installdirs' added line create directory for pic16
8315 headers in the installation path

8330 * src/z80/main.c (_parseOptions): fixed the portmode= command line
8331 option so that it actually works. Made it specific to the z80, since
8332 the gbz80 doesn't have these kinds of I/O ports.
8334 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8336 * device/include/z180.h,

8349 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8351 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
8352 changed interrupt vector table generation to only emit declared vectors.
8353 * device/include/Makefile.in: added missing backslash
8354 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)

8358 Mainly changes to support compilation of the device libraries
8359 * src/pic16/device.c: stack is allocated via symbol and not
8360 via literal number. The symbol is placed in the corresponding
8361 position of the data ram
8362 * (pic16_dump_section): relocatable and absolute uninitialized
8363 data are now emitted in sorted order to reduce section naming,
8364 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
8365 weren't marked as being in the access bank,
8367 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
8369 Added portion of GNU PIC Library under the directory
8370 device/include/pic16 and device/lib/pic16. These files
8371 contain the declarations of SFRs for the PIC18Fxx2 devices.
8372 The directory is initialized via configure from toplevel.
8374 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
8376 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
8377 the spilllocations to be compared correctly
8379 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
8381 * src/SDCCast.c (decorateType): fixed bug introduced today
8383 2004-01-12 Borut Razem <borut.razem AT siol.net>

8401 * doc/sdccman.lyx: Moved and added some sections, small changes
8402 all over. Telling LaTeX to be less strict with word spacing
8403 to better keep the right margin. Changed some notes about
8404 maintainance of the ports in section 3.2.1 - is it OK like this?
8406 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

8443 UPPER for immediate operands,
8444 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
8446 * src/pic16/peeph.def: all peepholes with movff are commented out,
8447 because there is a problem in the pcode peep optimizer,
8448 * src/pic16/ralloc.c: the register allocator can now reuse local

8450 * src/pic16/ralloc.h: added flag isLocal in structure regs,
8452 Added file src/pic16/NOTES with information about program writing on
8453 the current port version.

8485 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8488 * src/z80/main.c: added missed needLinkerScript flags (more than
8489 one port structure defined in these file)
8490 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

8506 needLinkerScript flag
8508 * src/pic16/gen.c (genAddrOf): fixed bug #863624
8509 * src/pic/glue.c: added variable udata_section_name to
8510 override default uninitialized data segment definition for

8512 * (pic14emitOverlay): modified to emit a commented overlay segment
8513 directive when no overlay data exist
8514 * (picglue): modified to emit uninitialized data segment
8515 according to udata_section_name

8525 2004-01-07 Borut Razem <borut.razem AT siol.net>
8527 * support/scripts/sdcc.nsi: update PATH
8528 * support/scripts/sdcc.ico: craeted
8530 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>

8541 include information about variables allocated to the overlay
8544 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8546 * as/mcs51/lkmain.c: Help about -Y option

8558 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8560 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
8561 (default behaviour).
8563 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8565 A python script to validate compiler diagnostic messages. It can be
8566 used to verify that sdcc complains about bad c source code and
8567 gives a good location of the error.
8568 * support/valdiag/Makefile,
8569 * support/valdiag/valdiag.py,
8570 * support/valdiag/tests/*
8572 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8585 * src/common.h: added ifndef/define/endif macros
8586 around the header file.
8587 Bug reported from Jesus Calvino-Fraga
8589 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8591 * sdcc.spec: updated
8592 * device/include/Makefile.in: don't install CVS directories
8593 * device/lib/Makefile.in: added removal of CVS directories after install
8594 * doc/Makefile: fixed install, added local_icons
8595 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8596 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8597 * src/ds390/gen.c (genRightShift): fixed bug #870788
8598 * src/SDCCast.c (decorateType): fixed bug #870781
8600 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8602 PIC16 port related changes:
8603 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8604 added variable stackPos,
8606 * gen.c: genCall, assignResultValue: added support for
8607 pushing/retrieving function parameters to/from stack,
8608 genFunction,genEndFunction: setup stack frame for the
8610 genAddrOf: will be changed according to bug 863624
8612 * added files genutils.c and genutils.h which contain gen*
8613 debugged and optimised functions extracted from gen.c
8615 * glue.c: added variable 'externs' which holds extern symbols,
8616 pic16emitRegularMap: is modified to properly handle relocatable
8617 symbols under the new scheme,
8618 pic16createInterruptVect: is modified
8619 pic16printPublics: is modified to emit 'global' assembler directives,
8620 added pic16_printExterns to print extern symbols,
8621 pic16glue: initializes stack/frame pointer in the beginning of
8622 the assembly output. Temporary hack, will be corrected later,
8623 because gplink yet does not support stack and SDCC does not
8624 yet support a type of crt0.o object to create the final binary.
8626 * Removed many lines that contain 8051 legacy code.
8627 * The code is finally placed under a 'code' directive.
8628 * Added port specific options.
8630 * _process_pragma: simplified since now we do not need *special*
8631 include file to define SFR registers. But a separate header
8632 will be needed. This will be developed later.
8633 * _pic16_parseOptions: added, parses port specific options:
8634 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8635 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8636 --preplace-udata-with=
8638 * _pic16_setDefaultOptions: modified to initialize section names,
8639 but hack is temporarly out of order since it needs improvement.
8640 * _pic16_genAssemblerPreamble: configuration words are emitted by
8641 their address instead of their name. This part is incomplete and
8642 supports only the 18Fxx2 devices. Other devices will emit an error
8643 during assembly since they do not contain the same set of config
8645 * _pic16_genIVT: is modified,
8647 * pcode.c: added definitions for some hardware registers that are needed
8649 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8650 All PCI entries are updated. Now LFSR is supported.
8651 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8652 * added pic16_newpCodeOpLit2 to support instructions with
8653 two literal arguments
8654 * pic16_pCode2str: corrected code that emits assembler instructions
8655 with two literal operands and those that have an access bit modifier
8656 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8657 this fixes a bug which caused some labels to be lost, when an
8658 assembler directive was added, i.e. banksel,
8659 * pic16_FixRegisterBanking: improved logic that causes the insertion
8661 * InlineFunction: functions that are called once, are not any more
8662 inlined. This can be a port option in the future,
8664 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8666 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8667 hold the corresponding uninitialized symbols,
8668 * pic16_allocProcessorRegister: registers have explicit marked the
8670 * pic16_allocInternalRegister: registers are explicit marked as
8672 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8673 processing list, so bit registers were lost,
8676 * ralloc.h: added field 'accessBank' and original symbol operand
8677 in register definition,
8678 * removed the field isMapped from register definition,
8680 ** Several functions have been removed from various sources:
8681 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8682 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8683 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8684 pic16_assignRelocatableRegisters
8686 ** others have been introduced:
8687 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8688 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8690 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8692 * support/scripts/inc2h.pl: changed definition of BIT_AT
8693 to emit 'sbit at' instead of 'bit at'. This was a request.
8695 PIC16 port related preliminary changes:
8696 * gen.c: prefixed function popRegFromString with
8697 pic16_ and all references to it corrected
8698 * pcode.c: all pic16_pc_* hardware registers prefixed
8699 with underscore (_),
8700 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8701 * ralloc.c: newReg(): when register is REG_SFR then
8702 set address to rIdx,
8703 pic16_allocProcessorRegister(): marks register wasUsed=0
8704 pic16_writeUsedRegs(): added a call to assign processor
8705 registers via pic16_assignFixedRegisters
8707 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8709 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8710 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8711 variables in unused register banks. Also the SSEG is placed
8712 wherever there is enough space for it, and IDATA can be anywhere
8713 in internal RAM. For now compile using -Wl-Y[stack_size].
8714 The mem file is different for this option as well, since it
8715 makes no sense of talking about DSEG lenght.
8717 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8719 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8720 in certain cases, e.g. when ROM assignment, patch provided
8721 from Albert den Haan.
8723 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

9766 A few small changes that speed up the peephole optimizer.
9770 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9772 Try to make the peephole optimizer smarter by maintaining
9773 an association between the assembly source code and the
9774 iCodes that originated them. Put this information to use
9775 with a new peephole rule condition "notVolatile" so that
9776 the rules can be aggressive yet still safe.
9781 * src/mcs51/peeph.def
9783 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9787 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9788 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9789 if the left or right operand symbols have the accuse flag set.
9791 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9793 Changed the type of the result of the ! (NOT) operator to char;
9794 previously it returned the same type as the source. This allows
9795 us to eliminate all the genFloatNot functions (all of its target
9796 implementations were very buggy) since !float can use the same
9799 * src/SDCCicode.c (ast2iCode): ! returns char
9800 * src/mcs51/gen.c (genNot, genNotFloat),
9801 * src/ds390/gen.c (genNot, genNotFloat),

9808 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9809 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9810 during interrupts. Ensure WSAVE is located at a shared bank address.
9811 2. Fixed page selection in some places
9812 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9813 the registers name strings.
9814 4. Fixed "signed / unsigned compare" compiler warnings.
9815 5. The PIC port manages its own allocation of the general purpose
9816 registers, but makes no attempt to reuse them. As a result when
9817 compiling it soon runs out of general purpose registers. Some
9818 additional code was added to the files pcode.c and device.c to walk
9819 through the function call tree and rename the registers so that they
9829 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9830 genPlus() & genMinus() when the result is the same as left or right
9832 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9836 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9838 Made bitfield a distinct type from bit so that bitfields
9839 convert as per ANSI C and bits retain their traditional
9840 boolean style behaviour. Implemented bitfield support in
9848 * src/ds390/gen.c: bit v bitfield split
9849 * src/z80/gen.c: New support for bitfields
9850 * support/regression/tests/bitfields.c: reenabled z80,
9853 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9855 Rules 246.x, 247.x relate to bitfields, the others speed up
9856 access to xdata mapped I/O devices.
9858 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9860 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9862 Cleaned up genPackBits and genUnpackBits and added two helper
9863 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9864 for literal assignments in genPackBits (thanks to Frieder for
9870 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9872 Fixed bug #748310 (pointer to function type mishandled when the
9873 function name is omitted). Also fixed a SIGSEGV when a function
9874 attribute (reentrant, etc) is used on a non-function or on a
9875 function but misplaced before the parameter list.
9877 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9879 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
9880 * support/Util/SDCCerr.h,
9881 * support/Util/SDCCerr.c: Added func attr misuse error msg

9902 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9904 Made the constant following the "interrupt" keyword optional. If
9905 omitted, the function will not automatically be given an entry
9906 in the interrupt vector table (similar to #pragma NOIV, but
9907 less syntacticly kludgy). The interrupt number is also now
9908 range checked. Also fixed a bug in the high order bit example
9915 * support/Util/SDCCerr.c
9916 * support/Util/SDCCerr.h
9919 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

9922 * src/SDCCicode.c (operandOperation): rewritten some ops
9923 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
9924 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9926 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9927 be re-activated by defining REDUCE_LITERALS)
9928 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
9929 unsigned, but are signed by default
9930 * src/SDCCval.c (constVal): rearranged
9931 * src/SDCCval.c (valMod): preliminary fix
9932 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9976 * src/SDCCval.c (valDiv, valMod): fixed signdness
9977 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
9978 signedness of modulo, left and right shift

10384 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
10385 the regression tests I'm not brave enough to enable 245.b, 245.c
10386 * doc/sdccman.lyx: added latex preamble for hyperref package.
10387 Using pdflatex this will give you a hyperlinked pdf file with

10437 * src/SDCCmain.c: linkOptions is changed to set *,
10438 added if/endif conditional macros to remove options help
10439 messages from optionsTable when a port is not configured, added
10440 support for the PIc16 port in the ports table, when executing
10441 the compiler with no port specified on command line, a default
10442 port is selected with the new macro DEFAULT_PORT which is
10443 defined in port.h, in setDefaultOptions() linkOptions is removed
10444 from initialization assignment, since now it is a set,
10445 parseCmdLine uses setParseWithComma for linkOptions, in
10446 linkEdit() linkOptions are accessed with new function indexSet()
10447 which returns the i'th item of a set variable. See SDCCset.c, in
10448 linkEdit() when calling buildCmdLine(), added linkOptions as
10449 last argument. Now users can pass arguments to gplink via the
10450 -Wl option, main() uses pic16glue() to glue up pic16 programs

10462 * src/pic16/glue.c: commented out some error producing lines
10463 * src/pic16/main.c: __config directives are commented out to stop
10464 gpasm complaining and test the linkage with gplink, _linkCmd and
10465 _asmCmd changed to be more gplink and gpasm friendly
10466 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10467 produced an error when parsed, peep rule 12 is added to utilize
10468 movff, but it is commented out since the pCode does not support
10469 yet a command with 2 address arguments
10471 2003-05-18 <johan AT balder>
10473 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

11601 overlaying area for it (uses RegBankUsed[4]).
11603 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11604 bank zero as used by default. By default aslink locates the stack
11605 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11606 the creation of the .mem file. Delegates the allocation of data area
11607 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11608 the begining of the stack area to aslink.
11610 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11611 glue() in SDCCglue.c creates an area for it.
11613 2002-09-03 Borut Razem <borut.razem AT siol.net>
11614 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11615 sdcc/src/pic/glue.c:
11616 introduced atexit() handler for teporay files removal in case of
11617 errors, assertions, ...
11619 2002-08-29 Borut Razem <borut.razem AT siol.net>
11620 * sdcc/support/cpp2/auto-host_vc_in.h:
11621 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11622 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11623 Maybe there is a similar problem with BORLANDC? It should be checked!
11625 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11626 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11627 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11628 was not executed, and the compiler (cl) launched a warning:
11629 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11631 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11632 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11634 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11635 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11637 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11638 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11639 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11640 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11641 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11642 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11643 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11644 - added Release configuration in VS projects
11645 - review of compiler an linker options
11646 - VC .exe files are generated in bin_vc directory, not to interfere
11647 with binaries generated from other projects (cygwin, mingw, bcc ...)
11649 * sdcc/src/yacc.dsp: added
11651 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11652 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11653 and insert the version number definitions from .version
11655 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11657 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11658 added - genarate auto-host.h using auto-host_vc_in.h as template
11661 removed from CVS, generated automatically
11663 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11664 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11666 2002-08-11 Borut Razem <borut.razem AT siol.net>
11667 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11669 2002-08-10 Borut Razem <borut.razem AT siol.net>
11670 * src/SDCCmain.c (main):
11671 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11672 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11673 The consequence was that some temporary files were not removed.
11676 unification of code in functions tempfilename() and tempfile():
11677 function tempnam() is defined in Visual Studio 6.0 and .NET
11679 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11681 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11682 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11683 - removed compiler command line option /WX: Treats all warnings as errors
11684 - update a list of source files, included into the project
11686 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11687 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11688 changed project type to Generic Project so that can be correcly converted to VS.NET project
11690 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11692 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11694 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11696 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11697 added return 0 statements after assert() to make compiler happy
11699 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11700 added newline in the def file to keep MSC compiler satisfied
11702 * sdcc/src/z80/gen.c:
11703 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11704 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11705 - solved MSC error in function aopDump()
11707 * sdcc_vc.h: define PREFIX as "\\sdcc"
11709 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
11710 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

11749 2002-03-28 Johan Knol <johan AT balder>
11751 * src/SDCCval.c: fixed bug #532436
11753 2002-03-14 Scott Dattalo <scott AT dattalo.com>

11758 Added -p option. Allows port dependent processor to be specified.
11761 Initialized the new field char *Processor field to NULL in all ports
11764 Compiler generated registers for interrupt context saving
11765 were not getting allocated.
11767 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
11770 Fixed left shift. Will promote the left side of a left shift
11771 if a) left shifting more than size of operand or b) when assigned
11772 to something size > size of left side

11882 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
11884 * sdcc/src/SDCCloop.c:
11885 Previous fix was not good. basic blocks that have "break" or "return" are
11886 not really partof a loop , but live ranges used in these blocks should
11887 be live thru the entire loop, so set partOfLoop but don't add them to
11890 2002-02-21 <johan AT FRIJA>
11892 * src/SDCCcse.c: fixed bug #514308
11894 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
