1664 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1666 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1667 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1669 One basic decision: e.g. src/clean.mk includes further files. In order
1670 to make this work there are two solutions:
1671 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1672 run configure on them. This way they can use
1673 'include $(srcdir)/port-clean.mk'
1674 - always include clean.mk by the Makefile at the same level. To avoid
1675 that `make clean` tries to include and build Makefile.dep the
1676 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1677 implemented, because now even `make uninstall` doesn't create
1678 Makefile.in. clean.mk could be eliminated by pasting it in
1681 * debugger/mcs51/Makefile.in: build own objects from library sources
1682 (SLIB, SDCC) in current directory
1684 * configure, configure.in: renamed --disable-device-lib-build in
1685 --disable-device-lib; added --enable-doc, the required tools are
1686 searched by configure; added result message; the toolchain for the
1687 belonging ports are now only built, if the port is enabled.
1689 * support/regression/*: all output is written in directory gen, because
1690 the fwk and ports directories don't livet in the build tree using vpath
1692 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1693 --disable-device-lib, added --enable-doc, added section VPATH
1695 * sim/ucsim/configure.in,
1696 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1697 z80 are enabled by default
1699 2006-04-24 Raphael Neider <rneider AT web.de>
1701 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1702 to config word, "pic14_"-prefixed some extern functions
1703 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1704 config word has been found
1705 * src/pic/device.h: added prototypes
1706 * src/pic/pcode.c: added "pic14_"-prefix where needed
1707 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
1709 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

1712 (pic14createInterruptVect): moved generating __config directives away

1722 registers that have not been assigned proper liveranges,
1723 fixes #1469504 and #1474602,
1724 (pCodeRegOptimizeRegUsage): fixed typo in comment
1726 2006-04-24 Borut Razem <borut.razem AT siol.net>
1728 * device/examples/main8051.c: deleted - it was removed from CVS
1729 24.mar.2000 and after that modified 18.feb.2001, so it reappered
1730 after the transition to Subversion
1731 * src/SDCCalloc.h: deleted - it was removed from CVS
1732 3.feb.2001 and after that modified 18.feb.2001, so it reappered

1994 * src/.version: increased version number to 2.5.5
1995 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1996 linking is done manually in pic16 port's _linkEdit,
1997 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1998 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1999 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
2000 allocate asmop as AOP_ACC,
2001 (aopForRemat): added parameter 'bool result' in function declaration,
2002 (pic16_aopGet): return AOP_ACC when accessing WREG,

2014 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
2015 call to allocReg, not by manually allocating a new one,
2016 (pic16_assignRegisters): now before going through the register
2017 allocating functions mark all registers as free. This eliminates some
2018 side effects resulting from peephole parser done earlier in the backbone

2081 'xinst' for initial support for Extended Instruction Support,
2082 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
2083 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
2084 port->fun_prefix anymore (may change later),
2085 (genFunction, genEndFunction): do not store/restore local registers for
2086 _main (this should take care the --main-return command line option in
2088 (genOr): removed some legacy pic-port instructions,
2089 * src/pic16/genarith.c (genAddLit): re-enabled old code because
2090 performing operations with SFR's causes data to be written more than
2091 once to each SFR. Perhaps SFRs should be handled in special cases...
2092 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
2094 * src/pic16/main.c (_process_pragma): stack bound checking did not take

2100 (commented out for reference), didn't account for some registers which
2101 were left marked 'not free' after a pointer operation. The change
2102 reduces register usage a lot in some cases

4371 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4373 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),

4377 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
4378 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
4379 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
4380 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
4381 always available in leading double underscore form. The C99 support is
4382 mostly missing, but it's a start.
4383 * support/regression/tests/bug-227710.c: fixed nonconforming use of
4384 reserved identifier "__data".
4386 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

4430 immedDom() returning wrong block; probably fixes bug #1160833)
4432 2005-03-20 Borut Razem <borut.razem AT siol.net>
4434 * support/scripts/inc2h.pl: WIN32 port

4462 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
4464 * device/lib/printf_large.c: removed inline assembly for portability and
4465 readability. Use printf_fast if speed or size are more important.
4466 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4467 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4469 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4471 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4472 prevent compiler warning
4474 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4476 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4477 moved to level 0 and declared as static. Also they are explicit
4478 placed in access bank. This was necessery because some times they
4479 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4480 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4481 optimizations. Currently only compare to unsigned char is implemented,
4482 * src/pic16/gen.c: added fReturnIdx array,
4483 * (struct resolvedIfx) is moved to gen.h and made public,
4484 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4485 * (aopForSym): added an optimization to directly store in stack of
4486 the operand of a SEND iCode,
4487 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4488 but as registers instead (AOP_REG) using the fReturnIdx array,
4489 * (pic16_freeAsmop): remove the freed register from the
4490 _G.sregsAlloc field,
4491 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4492 a compare of 'WREG',
4493 * (pic16_popGetTempRegCond): changed function prototype, now
4494 function takes also a bitVector argument v which holds the current
4495 set of registers that are allocated for stack access by aopForSym,
4496 registers allocated in aopForSym for accessing stack symbols are not
4497 any more part of the functions usedRegs field,
4498 * (genCall): some times aopOp is called for a stack variable to be
4499 send, aopForSym might perform the push, if this is true make sure
4500 that genCall doesn't push the variable twice by testing _G.resDirect,
4501 * (genFunction): changed testing for unspecified interrupt number
4502 from 256 to INTNO_UNSPEC,
4503 * modified selection scheme of frame pointer generation. Previously
4504 if function did use local registers a frame pointer was generated,
4505 now a frame pointer is generated only if function has arguments
4506 (that need PLUSW2 register access), or has stack arguments, or the
4507 compiler is not instructed to omit the frame pointer,
4508 * (genEndFunction): before restoring local registers that were saved
4509 in the function preamble, also restore the registers that *might*
4510 have been allocated for stack access,
4511 * (genRet): removed some old comments,
4512 * (genCmp, the active (RN's) version): added a call to the
4513 pic16_genCmp_special function to perform the compare with a more
4514 robust and optimized way,
4515 * (genInline): a feature has been added in inline code generation,
4516 which allows a wildcard variable substitution when writing inline
4517 assembly. Code is incomplete and experimental therefore undocumented,
4518 * (genCast): changed order of aopOp for result and right to allow
4519 aopForSym to directly load the result if possible,
4520 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4521 perform an optimized compare on some selected special occasions,
4522 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4523 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4524 generate an IVT any more,
4525 * src/pic16/main.c (pic16_optionsTable): added command line option
4527 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4528 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4530 * src/pic16/NOTES: Raphael Neider added in list of active developers
4531 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4532 jumptable_end to prevent bug #,
4533 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4534 inCond and outCond fields,
4535 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4536 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4537 turn off register spilling,
4538 * (packRegsForOneUse): synced with other ports' versions although it
4539 is not used currently,
4540 * (pic16_packRegisters): added an optimization while reading
4541 structure bitfields, some registers may be saved (malloc code is
4542 decreased by 80 bytes)
4544 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4546 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4547 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4548 this can be optimized more?
4550 2005-03-10 Raphael Neider <rneider AT web.de>
4552 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4553 genNearPointerGet): (hopefully) fixed access to bitfields via
4554 pointers (p->bitN = x; and x = p->bitN; failed)
4556 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
4558 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

4599 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
4600 to keep the correct label reference count when adding/removing references
4601 to labels. A peephole file using this is appended to patch #1144962.

4733 * src/pic16/main.c (_process_pragma): fixed another malloc bug
4734 (sizeof(sectNames) changed to sizeof(sectName))
4735 Both patches fix segfaults under MinGW.
4737 2005-01-23 Raphael Neider <rneider AT web.de>

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

5175 comparisons, and supports quoted literals
5176 * src/mcs51/peeph.def: restored rule 177.d with an extra condition
5178 2004-12-02 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

5186 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5188 Adding support for replacing ljmps with sjmps in jumptables
5189 generated for switch statements. For now you need to set the
5190 environment variable SDCC_SJMP_JUMPTABLE to enable this.
5191 Now 4 algorithms for mcs51 jumptable generation are used:
5192 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
5193 addresses loaded pc-relative for up to 112 cases and stack-pushing
5194 target addresses loaded with offset from dptr for up to 256 cases.
5196 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
5197 * src/mcs51/main.c: adapted constants for switch table generation
5198 * src/mcs51/peeph.def: added 260.x for replacing ljmp with sjmp

5218 2004-11-24 Vangelis Rokas <vrokas AT otenet.gr>
5220 Large cummulative patch for pic16 port.
5221 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
5222 to call when a stack overflow occurs,
5223 * (malloc.h): added CVS Id tag,
5224 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
5226 * added libc directory. The current version of LibC contains string
5227 functions, ctype functions and macros and some functions of the
5228 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
5229 be extensively tested in the future. Standard disclaimer here.
5230 Library is not automatically build yet. But one can build it by
5231 invoking 'make' inside the libc directory.
5232 * added ADC library under libio. Preliminary version yet.
5234 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
5235 * src/pic16/gen.c (aopForRemat): asmop size is filled by
5236 aopForRemat() now and not by pic16_aopOp(),
5237 * (pic16_popGetTempReg): removed warning messgae when allocating
5238 temporary registers, its a buggy feature and will be removed,
5239 * (pic16_popGet): set register instance field in AOP_CRY,
5240 * (pic16_outBitC): fixed for results in size greater than 1,
5241 * (genUminusFloat): fixed for pic16, ported code from mcs51,
5242 * (pic16_storeForReturn): optimized return of 0,
5243 * (genCmp): experimental code for new genCmp which uses PIC18's
5244 special compare&skip instructions. Initial tests fail some times
5245 with variables grater than 1 byte in size, so new code is disabled,
5246 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5248 * (genCast): began a fix to optimize the casting of a bit to another
5249 bit, now assigning a bitfield to another bitfield will fail, sorry,
5250 * src/pic16/main.c: disabled the use of lr-support feature,
5251 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
5252 * added some function prototypes, added function _debugf prototype,
5253 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
5254 bits with offset (case PO_GPR_BIT),
5255 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
5257 * (isBankInstruction): modified to return 0 for no banking instruction,
5258 and 1 for banking instruction,
5259 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
5260 caused stop processing pCodes after a inline assembly block,
5261 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
5262 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
5263 registers when it shouldn't,
5264 * src/pic16/ralloc.c (allocReg): add preliminary support for
5265 supporting a limited set of temporary registers,
5267 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5269 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
5270 genDataPointerSet): ensure assignments always copy in MSB to LSB
5272 (loadRegFromAop): recognize CLRH optimization,
5273 (genFunction): optimize RECEIVE iCodes in reentrant functions
5275 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5277 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
5278 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
5280 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

5286 * device/lib/_gptrget.c (_gptrget),
5287 * device/lib/_gptrgetc.c (_gptrgetc),
5288 * device/lib/_gptrput.c (_gptrput): _naked allows to use ret
5289 instead of sjmp to ret
5290 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
5291 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
5293 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

8275 loaded with the linker search paths (-L arguments) and the libraries
8276 to be linked with the current source (-l arguments). Changes
8277 currently will affect only the pic16 port.
8278 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8279 include path the port specific paths and port specific libraries,
8280 * gplink command now contains the $3 argument,
8281 * src/pic16/device.h,
8282 * src/pic16/device.c,: structure PIC_device is made public and
8283 renamed to PIC16_device, the same for variable Pics which is renamed
8284 to Pics16. Updated all references to them.
8285 * src/pic16/glue.c (pic16glue): corrected bug with code
8286 initialization which bypassed the variable initializations block.
8288 * device/lib/pic16/Makefile.rules: removed --penable-stack from
8289 COMPILE_FLAGS and added the --nostdinc option
8291 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8293 * device/include/mc68hc908jb8.h: Register defs for another member
8294 of the hc08 family. Contributed by Bjorn Bringert - thanks!
8296 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
8298 Documenting changes from previous commits.
8299 * configure.in (version 1.56),
8300 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8301 when generating output files to configure the pic16 library,
8302 but now I've commented it out, since gputils aren't installed in the
8303 SF compile farm, so library won't compile
8305 * device/lib/Makefile.in (version 1.56): initially I've added in
8306 target 'all' the prerequestive 'model-pic16' so it compiled the
8307 pic16 library, but now I've commented it out for the same reasons
8309 * added targets 'model-pic16' and 'objects-pic16' to compile the
8311 * added target 'port-specific-objects-pic16' to handle the
8312 generated libraries and copy them into the build/ directory
8313 * added target 'clean-intermediate-pic16' to clean intermediate
8314 files into pic16 directory
8315 * in target 'installdirs' added line to create directory pic16 in
8316 the installation path
8318 * device/include/Makefile.in (version 1.11): in target 'install'
8319 added lines to copy all header files to installation path,
8320 * in target 'installdirs' added line create directory for pic16
8321 headers in the installation path

8336 * src/z80/main.c (_parseOptions): fixed the portmode= command line
8337 option so that it actually works. Made it specific to the z80, since
8338 the gbz80 doesn't have these kinds of I/O ports.
8340 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8342 * device/include/z180.h,

8355 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8357 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
8358 changed interrupt vector table generation to only emit declared vectors.

8364 Mainly changes to support compilation of the device libraries
8365 * src/pic16/device.c: stack is allocated via symbol and not
8366 via literal number. The symbol is placed in the corresponding
8367 position of the data ram
8368 * (pic16_dump_section): relocatable and absolute uninitialized
8369 data are now emitted in sorted order to reduce section naming,
8370 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
8371 weren't marked as being in the access bank,
8373 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
8375 Added portion of GNU PIC Library under the directory
8376 device/include/pic16 and device/lib/pic16. These files
8377 contain the declarations of SFRs for the PIC18Fxx2 devices.
8378 The directory is initialized via configure from toplevel.
8380 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
8382 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
8383 the spilllocations to be compared correctly
8385 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
8387 * src/SDCCast.c (decorateType): fixed bug introduced today
8389 2004-01-12 Borut Razem <borut.razem AT siol.net>

8407 * doc/sdccman.lyx: Moved and added some sections, small changes
8408 all over. Telling LaTeX to be less strict with word spacing
8409 to better keep the right margin. Changed some notes about
8410 maintainance of the ports in section 3.2.1 - is it OK like this?
8412 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

8449 UPPER for immediate operands,
8450 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
8452 * src/pic16/peeph.def: all peepholes with movff are commented out,
8453 because there is a problem in the pcode peep optimizer,
8454 * src/pic16/ralloc.c: the register allocator can now reuse local
8455 function symbols for another function. This saves register usage.
8456 * src/pic16/ralloc.h: added flag isLocal in structure regs,
8458 Added file src/pic16/NOTES with information about program writing on
8459 the current port version.

8491 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8494 * src/z80/main.c: added missed needLinkerScript flags (more than
8495 one port structure defined in these file)
8496 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

8512 needLinkerScript flag
8514 * src/pic16/gen.c (genAddrOf): fixed bug #863624
8515 * src/pic/glue.c: added variable udata_section_name to
8516 override default uninitialized data segment definition for
8517 devices only with SHAREBANK memory (reported from Erik Epetrich)
8518 * (pic14emitOverlay): modified to emit a commented overlay segment
8519 directive when no overlay data exist
8520 * (picglue): modified to emit uninitialized data segment
8521 according to udata_section_name

8527 * src/pic16/main.c: added $l in _asmCmd, changed extension for
8528 object file from '.rel' to '.o' in port->linker structure,

8531 2004-01-07 Borut Razem <borut.razem AT siol.net>
8533 * support/scripts/sdcc.nsi: update PATH
8534 * support/scripts/sdcc.ico: craeted

8547 include information about variables allocated to the overlay
8550 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8552 * as/mcs51/lkmain.c: Help about -Y option

8564 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8566 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
8567 (default behaviour).
8569 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8571 A python script to validate compiler diagnostic messages. It can be
8572 used to verify that sdcc complains about bad c source code and
8573 gives a good location of the error.
8574 * support/valdiag/Makefile,
8575 * support/valdiag/valdiag.py,
8576 * support/valdiag/tests/*
8578 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8591 * src/common.h: added ifndef/define/endif macros
8592 around the header file.
8593 Bug reported from Jesus Calvino-Fraga
8595 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8597 * sdcc.spec: updated
8598 * device/include/Makefile.in: don't install CVS directories
8599 * device/lib/Makefile.in: added removal of CVS directories after install
8600 * doc/Makefile: fixed install, added local_icons
8601 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8602 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8603 * src/ds390/gen.c (genRightShift): fixed bug #870788
8604 * src/SDCCast.c (decorateType): fixed bug #870781
8606 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8608 PIC16 port related changes:
8609 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8610 added variable stackPos,
8612 * gen.c: genCall, assignResultValue: added support for
8613 pushing/retrieving function parameters to/from stack,
8614 genFunction,genEndFunction: setup stack frame for the
8616 genAddrOf: will be changed according to bug 863624
8618 * added files genutils.c and genutils.h which contain gen*
8619 debugged and optimised functions extracted from gen.c
8621 * glue.c: added variable 'externs' which holds extern symbols,
8622 pic16emitRegularMap: is modified to properly handle relocatable
8623 symbols under the new scheme,
8624 pic16createInterruptVect: is modified
8625 pic16printPublics: is modified to emit 'global' assembler directives,
8626 added pic16_printExterns to print extern symbols,
8627 pic16glue: initializes stack/frame pointer in the beginning of
8628 the assembly output. Temporary hack, will be corrected later,
8629 because gplink yet does not support stack and SDCC does not
8630 yet support a type of crt0.o object to create the final binary.
8632 * Removed many lines that contain 8051 legacy code.
8633 * The code is finally placed under a 'code' directive.
8634 * Added port specific options.
8636 * _process_pragma: simplified since now we do not need *special*
8637 include file to define SFR registers. But a separate header
8638 will be needed. This will be developed later.
8639 * _pic16_parseOptions: added, parses port specific options:
8640 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8641 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8642 --preplace-udata-with=
8644 * _pic16_setDefaultOptions: modified to initialize section names,
8645 but hack is temporarly out of order since it needs improvement.
8646 * _pic16_genAssemblerPreamble: configuration words are emitted by
8647 their address instead of their name. This part is incomplete and
8648 supports only the 18Fxx2 devices. Other devices will emit an error
8649 during assembly since they do not contain the same set of config
8651 * _pic16_genIVT: is modified,
8653 * pcode.c: added definitions for some hardware registers that are needed
8655 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8656 All PCI entries are updated. Now LFSR is supported.
8657 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8658 * added pic16_newpCodeOpLit2 to support instructions with
8659 two literal arguments
8660 * pic16_pCode2str: corrected code that emits assembler instructions
8661 with two literal operands and those that have an access bit modifier
8662 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8663 this fixes a bug which caused some labels to be lost, when an
8664 assembler directive was added, i.e. banksel,
8665 * pic16_FixRegisterBanking: improved logic that causes the insertion
8667 * InlineFunction: functions that are called once, are not any more
8668 inlined. This can be a port option in the future,
8670 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8672 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8673 hold the corresponding uninitialized symbols,
8674 * pic16_allocProcessorRegister: registers have explicit marked the
8676 * pic16_allocInternalRegister: registers are explicit marked as
8678 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8679 processing list, so bit registers were lost,
8682 * ralloc.h: added field 'accessBank' and original symbol operand
8683 in register definition,
8684 * removed the field isMapped from register definition,
8686 ** Several functions have been removed from various sources:
8687 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8688 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8689 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8690 pic16_assignRelocatableRegisters
8692 ** others have been introduced:
8693 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8694 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8696 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8698 * support/scripts/inc2h.pl: changed definition of BIT_AT
8699 to emit 'sbit at' instead of 'bit at'. This was a request.
8701 PIC16 port related preliminary changes:
8702 * gen.c: prefixed function popRegFromString with
8703 pic16_ and all references to it corrected
8704 * pcode.c: all pic16_pc_* hardware registers prefixed
8705 with underscore (_),
8706 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8707 * ralloc.c: newReg(): when register is REG_SFR then
8708 set address to rIdx,
8709 pic16_allocProcessorRegister(): marks register wasUsed=0
8710 pic16_writeUsedRegs(): added a call to assign processor
8711 registers via pic16_assignFixedRegisters
8713 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8715 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8716 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8717 variables in unused register banks. Also the SSEG is placed
8718 wherever there is enough space for it, and IDATA can be anywhere
8719 in internal RAM. For now compile using -Wl-Y[stack_size].
8720 The mem file is different for this option as well, since it
8721 makes no sense of talking about DSEG lenght.
8723 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8725 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8726 in certain cases, e.g. when ROM assignment, patch provided
8727 from Albert den Haan.
8729 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

9772 A few small changes that speed up the peephole optimizer.
9776 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9778 Try to make the peephole optimizer smarter by maintaining
9779 an association between the assembly source code and the
9780 iCodes that originated them. Put this information to use
9781 with a new peephole rule condition "notVolatile" so that
9782 the rules can be aggressive yet still safe.
9787 * src/mcs51/peeph.def
9789 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9793 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9794 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9795 if the left or right operand symbols have the accuse flag set.
9797 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9799 Changed the type of the result of the ! (NOT) operator to char;
9800 previously it returned the same type as the source. This allows
9801 us to eliminate all the genFloatNot functions (all of its target
9802 implementations were very buggy) since !float can use the same
9805 * src/SDCCicode.c (ast2iCode): ! returns char
9806 * src/mcs51/gen.c (genNot, genNotFloat),
9807 * src/ds390/gen.c (genNot, genNotFloat),
9808 * src/z80/gen.c (genNot, genNotFloat),
9809 * src/pic/gen.c (genNot, genNotFloat),
9810 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat

9814 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9815 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9816 during interrupts. Ensure WSAVE is located at a shared bank address.
9817 2. Fixed page selection in some places
9818 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9819 the registers name strings.
9820 4. Fixed "signed / unsigned compare" compiler warnings.
9821 5. The PIC port manages its own allocation of the general purpose
9822 registers, but makes no attempt to reuse them. As a result when
9823 compiling it soon runs out of general purpose registers. Some
9824 additional code was added to the files pcode.c and device.c to walk
9825 through the function call tree and rename the registers so that they
9835 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9836 genPlus() & genMinus() when the result is the same as left or right
9838 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9842 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9844 Made bitfield a distinct type from bit so that bitfields
9845 convert as per ANSI C and bits retain their traditional
9846 boolean style behaviour. Implemented bitfield support in
9854 * src/ds390/gen.c: bit v bitfield split
9855 * src/z80/gen.c: New support for bitfields
9856 * support/regression/tests/bitfields.c: reenabled z80,
9859 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9861 Rules 246.x, 247.x relate to bitfields, the others speed up
9862 access to xdata mapped I/O devices.
9864 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9866 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9868 Cleaned up genPackBits and genUnpackBits and added two helper
9869 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9870 for literal assignments in genPackBits (thanks to Frieder for
9876 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9878 Fixed bug #748310 (pointer to function type mishandled when the
9879 function name is omitted). Also fixed a SIGSEGV when a function
9880 attribute (reentrant, etc) is used on a non-function or on a
9881 function but misplaced before the parameter list.
9883 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9885 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

9908 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9910 Made the constant following the "interrupt" keyword optional. If
9911 omitted, the function will not automatically be given an entry
9912 in the interrupt vector table (similar to #pragma NOIV, but
9913 less syntacticly kludgy). The interrupt number is also now
9914 range checked. Also fixed a bug in the high order bit example

9928 * src/SDCCicode.c (operandOperation): rewritten some ops
9929 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
9930 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9932 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9933 be re-activated by defining REDUCE_LITERALS)
9934 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
9935 unsigned, but are signed by default
9936 * src/SDCCval.c (constVal): rearranged
9937 * src/SDCCval.c (valMod): preliminary fix
9938 * src/SDCCval.c (valCastLiteral): use TYPE_* types

10390 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
10391 the regression tests I'm not brave enough to enable 245.b, 245.c
10392 * doc/sdccman.lyx: added latex preamble for hyperref package.
10393 Using pdflatex this will give you a hyperlinked pdf file with
10394 bookmarks. (prepend '%' before /usepackage if this breaks something)

10444 added if/endif conditional macros to remove options help
10445 messages from optionsTable when a port is not configured, added
10446 support for the PIc16 port in the ports table, when executing
10447 the compiler with no port specified on command line, a default
10448 port is selected with the new macro DEFAULT_PORT which is
10449 defined in port.h, in setDefaultOptions() linkOptions is removed
10450 from initialization assignment, since now it is a set,
10451 parseCmdLine uses setParseWithComma for linkOptions, in
10452 linkEdit() linkOptions are accessed with new function indexSet()
10453 which returns the i'th item of a set variable. See SDCCset.c, in
10454 linkEdit() when calling buildCmdLine(), added linkOptions as
10455 last argument. Now users can pass arguments to gplink via the
10456 -Wl option, main() uses pic16glue() to glue up pic16 programs

10468 * src/pic16/glue.c: commented out some error producing lines
10469 * src/pic16/main.c: __config directives are commented out to stop
10470 gpasm complaining and test the linkage with gplink, _linkCmd and
10471 _asmCmd changed to be more gplink and gpasm friendly
10472 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10473 produced an error when parsed, peep rule 12 is added to utilize
10474 movff, but it is commented out since the pCode does not support
10475 yet a command with 2 address arguments
10477 2003-05-18 <johan AT balder>
10479 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

11604 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11606 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11607 overlaying area for it (uses RegBankUsed[4]).
11609 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11610 bank zero as used by default. By default aslink locates the stack
11611 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11612 the creation of the .mem file. Delegates the allocation of data area
11613 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11614 the begining of the stack area to aslink.
11616 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11617 glue() in SDCCglue.c creates an area for it.
11619 2002-09-03 Borut Razem <borut.razem AT siol.net>
11620 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11621 sdcc/src/pic/glue.c:
11622 introduced atexit() handler for teporay files removal in case of
11623 errors, assertions, ...
11625 2002-08-29 Borut Razem <borut.razem AT siol.net>
11626 * sdcc/support/cpp2/auto-host_vc_in.h:
11627 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11628 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11629 Maybe there is a similar problem with BORLANDC? It should be checked!
11631 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11632 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11633 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11634 was not executed, and the compiler (cl) launched a warning:
11635 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11637 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11638 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11640 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11641 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11643 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11644 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11645 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11646 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11647 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11648 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11649 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11650 - added Release configuration in VS projects
11651 - review of compiler an linker options
11652 - VC .exe files are generated in bin_vc directory, not to interfere
11653 with binaries generated from other projects (cygwin, mingw, bcc ...)
11655 * sdcc/src/yacc.dsp: added
11657 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11658 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11659 and insert the version number definitions from .version
11661 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11663 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11664 added - genarate auto-host.h using auto-host_vc_in.h as template
11667 removed from CVS, generated automatically
11669 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11670 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11672 2002-08-11 Borut Razem <borut.razem AT siol.net>
11673 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11675 2002-08-10 Borut Razem <borut.razem AT siol.net>
11676 * src/SDCCmain.c (main):
11677 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11678 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11679 The consequence was that some temporary files were not removed.
11682 unification of code in functions tempfilename() and tempfile():
11683 function tempnam() is defined in Visual Studio 6.0 and .NET
11685 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11687 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11688 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11689 - removed compiler command line option /WX: Treats all warnings as errors
11690 - update a list of source files, included into the project
11692 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11693 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11694 changed project type to Generic Project so that can be correcly converted to VS.NET project
11696 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11698 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11700 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11702 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11703 added return 0 statements after assert() to make compiler happy
11705 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11706 added newline in the def file to keep MSC compiler satisfied
11708 * sdcc/src/z80/gen.c:
11709 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11710 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11711 - solved MSC error in function aopDump()
11713 * sdcc_vc.h: define PREFIX as "\\sdcc"
11715 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
11716 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

11764 Added -p option. Allows port dependent processor to be specified.
11767 Initialized the new field char *Processor field to NULL in all ports
11770 Compiler generated registers for interrupt context saving
11771 were not getting allocated.
11773 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
11776 Fixed left shift. Will promote the left side of a left shift
11777 if a) left shifting more than size of operand or b) when assigned
11778 to something size > size of left side

11888 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
11890 * sdcc/src/SDCCloop.c:
11891 Previous fix was not good. basic blocks that have "break" or "return" are
11892 not really partof a loop , but live ranges used in these blocks should
11893 be live thru the entire loop, so set partOfLoop but don't add them to
11896 2002-02-21 <johan AT FRIJA>
11898 * src/SDCCcse.c: fixed bug #514308
11900 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
