1576 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1578 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1579 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1581 One basic decision: e.g. src/clean.mk includes further files. In order
1582 to make this work there are two solutions:
1583 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1584 run configure on them. This way they can use
1585 'include $(srcdir)/port-clean.mk'
1586 - always include clean.mk by the Makefile at the same level. To avoid
1587 that `make clean` tries to include and build Makefile.dep the
1588 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1589 implemented, because now even `make uninstall` doesn't create
1590 Makefile.in. clean.mk could be eliminated by pasting it in
1593 * debugger/mcs51/Makefile.in: build own objects from library sources
1594 (SLIB, SDCC) in current directory
1596 * configure, configure.in: renamed --disable-device-lib-build in
1597 --disable-device-lib; added --enable-doc, the required tools are
1598 searched by configure; added result message; the toolchain for the
1599 belonging ports are now only built, if the port is enabled.
1601 * support/regression/*: all output is written in directory gen, because
1602 the fwk and ports directories don't livet in the build tree using vpath
1604 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1605 --disable-device-lib, added --enable-doc, added section VPATH
1607 * sim/ucsim/configure.in,
1608 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1609 z80 are enabled by default
1611 2006-04-24 Raphael Neider <rneider AT web.de>
1613 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1614 to config word, "pic14_"-prefixed some extern functions
1615 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1616 config word has been found
1617 * src/pic/device.h: added prototypes
1618 * src/pic/pcode.c: added "pic14_"-prefix where needed
1619 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
1621 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

1624 (pic14createInterruptVect): moved generating __config directives away

1635 fixes #1469504 and #1474602,
1636 (pCodeRegOptimizeRegUsage): fixed typo in comment

1859 2006-04-05 Maarten Brock <sourceforge.brock AT dse.nl>
1861 * src/mcs51/gen.c (genCall): fixed bug 1457608
1863 2006-03-30 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

1868 2006-03-29 Maarten Brock <sourceforge.brock AT dse.nl>
1870 * src/SDCCpeeph.c (operandsLiteral): new, added,

1882 implemented patch 1120823 Thanks to Willy De la Court (normal
1883 interrupts need an interrupt number now if they are made critical),
1884 and enabled nesting of critical functions though not for gbz80
1885 (genCritical, genEndCritical): added functions
1886 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1887 * src/z80/mappings.i: added "ei" to all mappings

1892 submitted by the Debian SDCC maintainer Aurelien Jarno:
1893 "Credits goes to Martin Michlmayr, who rebuilt the whole Debian
1894 archive with gcc 4.1 on mips and wrote the patch"
1896 2006-03-16 Raphael Neider <rneider AT web.de>
1898 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
1899 the left operand is shorter than the result (c* = lit-c* + int),
1901 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1904 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1906 * src/.version: increased version number to 2.5.5
1907 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1908 linking is done manually in pic16 port's _linkEdit,
1909 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1910 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1911 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1912 allocate asmop as AOP_ACC,
1913 (aopForRemat): added parameter 'bool result' in function declaration,
1914 (pic16_aopGet): return AOP_ACC when accessing WREG,
1915 (pic16_popGetTempReg): minor modification,
1916 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
1917 'pic16_allocWithIdx',

1924 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
1926 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1927 call to allocReg, not by manually allocating a new one,
1928 (pic16_assignRegisters): now before going through the register
1929 allocating functions mark all registers as free. This eliminates some
1930 side effects resulting from peephole parser done earlier in the backbone
1932 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
1934 * src/SDCCicode.c (geniCodeLogic),

1990 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1991 which dumps before the function entry point a data byte which represents
1992 the number of the local variables used by the specified function, added
1993 'xinst' for initial support for Extended Instruction Support,
1994 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1995 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1996 port->fun_prefix anymore (may change later),
1997 (genFunction, genEndFunction): do not store/restore local registers for
1998 _main (this should take care the --main-return command line option in
2000 (genOr): removed some legacy pic-port instructions,
2001 * src/pic16/genarith.c (genAddLit): re-enabled old code because
2002 performing operations with SFR's causes data to be written more than
2003 once to each SFR. Perhaps SFRs should be handled in special cases...
2004 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
2006 * src/pic16/main.c (_process_pragma): stack bound checking did not take
2007 into account for stack starting position,

2009 --extended or -y for Extended Instruction Support,
2010 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
2011 (deassignLRs): *** perhaps the most important change, old 'for' code
2012 (commented out for reference), didn't account for some registers which
2013 were left marked 'not free' after a pointer operation. The change
2014 reduces register usage a lot in some cases

4340 * src/SDCCBBlock.h (struct ebbIndex): new struct that keeps two copies
4341 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
4342 immedDom() returning wrong block; probably fixes bug #1160833)
4344 2005-03-20 Borut Razem <borut.razem AT siol.net>
4346 * support/scripts/inc2h.pl: WIN32 port
4348 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
4350 * device/lib/makefile.in: added abs.c and labs.c
4352 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
4354 * device/include/stdint.h: added
4355 * device/lib/abs.c: added
4356 * device/lib/labs.c: added
4357 * device/include/stdlib.h: added abs() and labs() prototypes
4358 * device/lib/libsdcc.lib: added abs and labs
4359 * device/include/float.h,
4360 * device/lib/_fsmul.c,
4361 * device/lib/printf_fast.c,
4362 * device/lib/printf_tiny.c: updated comments
4364 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4366 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
4369 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4371 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
4372 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
4374 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
4376 * device/lib/printf_large.c: removed inline assembly for portability and
4377 readability. Use printf_fast if speed or size are more important.
4378 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4379 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4381 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4383 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4384 prevent compiler warning
4386 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4388 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4389 moved to level 0 and declared as static. Also they are explicit
4390 placed in access bank. This was necessery because some times they
4391 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4392 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4393 optimizations. Currently only compare to unsigned char is implemented,
4394 * src/pic16/gen.c: added fReturnIdx array,
4395 * (struct resolvedIfx) is moved to gen.h and made public,
4396 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4397 * (aopForSym): added an optimization to directly store in stack of
4398 the operand of a SEND iCode,
4399 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4400 but as registers instead (AOP_REG) using the fReturnIdx array,
4401 * (pic16_freeAsmop): remove the freed register from the
4402 _G.sregsAlloc field,
4403 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4404 a compare of 'WREG',
4405 * (pic16_popGetTempRegCond): changed function prototype, now
4406 function takes also a bitVector argument v which holds the current
4407 set of registers that are allocated for stack access by aopForSym,
4408 registers allocated in aopForSym for accessing stack symbols are not
4409 any more part of the functions usedRegs field,
4410 * (genCall): some times aopOp is called for a stack variable to be
4411 send, aopForSym might perform the push, if this is true make sure
4412 that genCall doesn't push the variable twice by testing _G.resDirect,
4413 * (genFunction): changed testing for unspecified interrupt number
4414 from 256 to INTNO_UNSPEC,
4415 * modified selection scheme of frame pointer generation. Previously
4416 if function did use local registers a frame pointer was generated,
4417 now a frame pointer is generated only if function has arguments
4418 (that need PLUSW2 register access), or has stack arguments, or the
4419 compiler is not instructed to omit the frame pointer,
4420 * (genEndFunction): before restoring local registers that were saved
4421 in the function preamble, also restore the registers that *might*
4422 have been allocated for stack access,
4423 * (genRet): removed some old comments,
4424 * (genCmp, the active (RN's) version): added a call to the
4425 pic16_genCmp_special function to perform the compare with a more
4426 robust and optimized way,
4427 * (genInline): a feature has been added in inline code generation,
4428 which allows a wildcard variable substitution when writing inline
4429 assembly. Code is incomplete and experimental therefore undocumented,
4430 * (genCast): changed order of aopOp for result and right to allow
4431 aopForSym to directly load the result if possible,
4432 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4433 perform an optimized compare on some selected special occasions,
4434 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4435 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4436 generate an IVT any more,
4437 * src/pic16/main.c (pic16_optionsTable): added command line option
4439 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4440 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4442 * src/pic16/NOTES: Raphael Neider added in list of active developers
4443 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4444 jumptable_end to prevent bug #,
4445 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4446 inCond and outCond fields,
4447 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4448 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4449 turn off register spilling,
4450 * (packRegsForOneUse): synced with other ports' versions although it
4451 is not used currently,
4452 * (pic16_packRegisters): added an optimization while reading
4453 structure bitfields, some registers may be saved (malloc code is
4454 decreased by 80 bytes)
4456 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4458 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4459 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4460 this can be optimized more?
4462 2005-03-10 Raphael Neider <rneider AT web.de>
4464 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4465 genNearPointerGet): (hopefully) fixed access to bitfields via
4466 pointers (p->bitN = x; and x = p->bitN; failed)
4468 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

4511 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
4512 to keep the correct label reference count when adding/removing references
4513 to labels. A peephole file using this is appended to patch #1144962.

4655 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
4656 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
4657 this might fix SIGSEGVs on MinGW...
4658 * src/SDCCopt.c (killDeadCode): restored original behaviour
4659 (volatile operands might get thrown away though)
4661 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

4745 * (genUminus): rewritten to for efficiency
4746 * (genNearPointer[GS]et): enforce reloading of FSR0 (was still
4747 used uninitialized in some cases)
4748 * (genCast): upcasting a 16bit int to a 24bit GPOINTER may not
4749 copy the third byte from the int -- now assumes 0x80 (data memory)
4750 * src/pic16/genarith.c (pic16_genPlus): fixed bug when swapping
4751 operands (genAddLit expects the iCode's operands to swapped as
4752 well), fixed leftover bytes (crashed for short left operands)

5100 Adding support for replacing ljmps with sjmps in jumptables
5101 generated for switch statements. For now you need to set the
5102 environment variable SDCC_SJMP_JUMPTABLE to enable this.
5103 Now 4 algorithms for mcs51 jumptable generation are used:
5104 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
5105 addresses loaded pc-relative for up to 112 cases and stack-pushing
5106 target addresses loaded with offset from dptr for up to 256 cases.

5136 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
5138 * added libc directory. The current version of LibC contains string
5139 functions, ctype functions and macros and some functions of the
5140 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
5141 be extensively tested in the future. Standard disclaimer here.
5142 Library is not automatically build yet. But one can build it by

5154 * (pic16_storeForReturn): optimized return of 0,
5155 * (genCmp): experimental code for new genCmp which uses PIC18's
5156 special compare&skip instructions. Initial tests fail some times
5157 with variables grater than 1 byte in size, so new code is disabled,
5158 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5160 * (genCast): began a fix to optimize the casting of a bit to another
5161 bit, now assigning a bitfield to another bitfield will fail, sorry,

5170 and 1 for banking instruction,
5171 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
5172 caused stop processing pCodes after a inline assembly block,
5173 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

5175 registers when it shouldn't,
5176 * src/pic16/ralloc.c (allocReg): add preliminary support for
5177 supporting a limited set of temporary registers,
5179 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5181 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,

5184 (loadRegFromAop): recognize CLRH optimization,
5185 (genFunction): optimize RECEIVE iCodes in reentrant functions
5187 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8184 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
8186 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
8187 loaded with the linker search paths (-L arguments) and the libraries
8188 to be linked with the current source (-l arguments). Changes
8189 currently will affect only the pic16 port.
8190 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8191 include path the port specific paths and port specific libraries,
8192 * gplink command now contains the $3 argument,
8193 * src/pic16/device.h,
8194 * src/pic16/device.c,: structure PIC_device is made public and
8195 renamed to PIC16_device, the same for variable Pics which is renamed

8210 Documenting changes from previous commits.
8211 * configure.in (version 1.56),
8212 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8213 when generating output files to configure the pic16 library,
8214 but now I've commented it out, since gputils aren't installed in the
8215 SF compile farm, so library won't compile
8217 * device/lib/Makefile.in (version 1.56): initially I've added in
8218 target 'all' the prerequestive 'model-pic16' so it compiled the
8219 pic16 library, but now I've commented it out for the same reasons
8221 * added targets 'model-pic16' and 'objects-pic16' to compile the
8223 * added target 'port-specific-objects-pic16' to handle the
8224 generated libraries and copy them into the build/ directory
8225 * added target 'clean-intermediate-pic16' to clean intermediate
8226 files into pic16 directory
8227 * in target 'installdirs' added line to create directory pic16 in
8228 the installation path
8230 * device/include/Makefile.in (version 1.11): in target 'install'
8231 added lines to copy all header files to installation path,
8232 * in target 'installdirs' added line create directory for pic16
8233 headers in the installation path

8248 * src/z80/main.c (_parseOptions): fixed the portmode= command line
8249 option so that it actually works. Made it specific to the z80, since
8250 the gbz80 doesn't have these kinds of I/O ports.
8252 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8254 * device/include/z180.h,

8276 Mainly changes to support compilation of the device libraries
8277 * src/pic16/device.c: stack is allocated via symbol and not
8278 via literal number. The symbol is placed in the corresponding
8279 position of the data ram
8280 * (pic16_dump_section): relocatable and absolute uninitialized
8281 data are now emitted in sorted order to reduce section naming,
8282 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
8283 weren't marked as being in the access bank,
8285 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
8287 Added portion of GNU PIC Library under the directory
8288 device/include/pic16 and device/lib/pic16. These files
8289 contain the declarations of SFRs for the PIC18Fxx2 devices.
8290 The directory is initialized via configure from toplevel.
8292 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
8294 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

8317 2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8319 * doc/sdccman.lyx: Moved and added some sections, small changes
8320 all over. Telling LaTeX to be less strict with word spacing
8321 to better keep the right margin. Changed some notes about
8322 maintainance of the ports in section 3.2.1 - is it OK like this?
8324 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
8326 SDCC source changes:
8327 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

8333 processor registers declared internally by the port are emitted in
8334 the translation as equates,
8335 * src/pic16/gen.c: inline code is passed unprocessed to the

8361 UPPER for immediate operands,
8362 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
8364 * src/pic16/peeph.def: all peepholes with movff are commented out,
8365 because there is a problem in the pcode peep optimizer,
8366 * src/pic16/ralloc.c: the register allocator can now reuse local

8476 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8478 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
8479 (default behaviour).
8481 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8483 A python script to validate compiler diagnostic messages. It can be
8484 used to verify that sdcc complains about bad c source code and
8485 gives a good location of the error.
8486 * support/valdiag/Makefile,
8487 * support/valdiag/valdiag.py,
8488 * support/valdiag/tests/*

8504 around the header file.
8505 Bug reported from Jesus Calvino-Fraga
8507 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8509 * sdcc.spec: updated
8510 * device/include/Makefile.in: don't install CVS directories
8511 * device/lib/Makefile.in: added removal of CVS directories after install
8512 * doc/Makefile: fixed install, added local_icons
8513 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8514 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8515 * src/ds390/gen.c (genRightShift): fixed bug #870788
8516 * src/SDCCast.c (decorateType): fixed bug #870781
8518 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8520 PIC16 port related changes:
8521 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8522 added variable stackPos,
8524 * gen.c: genCall, assignResultValue: added support for
8525 pushing/retrieving function parameters to/from stack,
8526 genFunction,genEndFunction: setup stack frame for the
8528 genAddrOf: will be changed according to bug 863624
8530 * added files genutils.c and genutils.h which contain gen*
8531 debugged and optimised functions extracted from gen.c
8533 * glue.c: added variable 'externs' which holds extern symbols,
8534 pic16emitRegularMap: is modified to properly handle relocatable
8535 symbols under the new scheme,
8536 pic16createInterruptVect: is modified
8537 pic16printPublics: is modified to emit 'global' assembler directives,
8538 added pic16_printExterns to print extern symbols,
8539 pic16glue: initializes stack/frame pointer in the beginning of
8540 the assembly output. Temporary hack, will be corrected later,
8541 because gplink yet does not support stack and SDCC does not
8542 yet support a type of crt0.o object to create the final binary.
8544 * Removed many lines that contain 8051 legacy code.
8545 * The code is finally placed under a 'code' directive.
8546 * Added port specific options.
8548 * _process_pragma: simplified since now we do not need *special*
8549 include file to define SFR registers. But a separate header
8550 will be needed. This will be developed later.
8551 * _pic16_parseOptions: added, parses port specific options:
8552 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8553 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8554 --preplace-udata-with=
8556 * _pic16_setDefaultOptions: modified to initialize section names,
8557 but hack is temporarly out of order since it needs improvement.
8558 * _pic16_genAssemblerPreamble: configuration words are emitted by
8559 their address instead of their name. This part is incomplete and
8560 supports only the 18Fxx2 devices. Other devices will emit an error
8561 during assembly since they do not contain the same set of config
8563 * _pic16_genIVT: is modified,
8565 * pcode.c: added definitions for some hardware registers that are needed
8567 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8568 All PCI entries are updated. Now LFSR is supported.
8569 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8570 * added pic16_newpCodeOpLit2 to support instructions with
8571 two literal arguments
8572 * pic16_pCode2str: corrected code that emits assembler instructions
8573 with two literal operands and those that have an access bit modifier
8574 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8575 this fixes a bug which caused some labels to be lost, when an
8576 assembler directive was added, i.e. banksel,
8577 * pic16_FixRegisterBanking: improved logic that causes the insertion
8579 * InlineFunction: functions that are called once, are not any more
8580 inlined. This can be a port option in the future,
8582 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8584 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8585 hold the corresponding uninitialized symbols,
8586 * pic16_allocProcessorRegister: registers have explicit marked the
8588 * pic16_allocInternalRegister: registers are explicit marked as
8590 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8591 processing list, so bit registers were lost,
8594 * ralloc.h: added field 'accessBank' and original symbol operand
8595 in register definition,
8596 * removed the field isMapped from register definition,
8598 ** Several functions have been removed from various sources:
8599 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8600 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8601 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8602 pic16_assignRelocatableRegisters
8604 ** others have been introduced:
8605 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8606 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8608 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8610 * support/scripts/inc2h.pl: changed definition of BIT_AT
8611 to emit 'sbit at' instead of 'bit at'. This was a request.
8613 PIC16 port related preliminary changes:
8614 * gen.c: prefixed function popRegFromString with
8615 pic16_ and all references to it corrected
8616 * pcode.c: all pic16_pc_* hardware registers prefixed
8617 with underscore (_),
8618 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8619 * ralloc.c: newReg(): when register is REG_SFR then
8620 set address to rIdx,
8621 pic16_allocProcessorRegister(): marks register wasUsed=0
8622 pic16_writeUsedRegs(): added a call to assign processor
8623 registers via pic16_assignFixedRegisters
8625 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8627 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8628 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8629 variables in unused register banks. Also the SSEG is placed
8630 wherever there is enough space for it, and IDATA can be anywhere
8631 in internal RAM. For now compile using -Wl-Y[stack_size].
8632 The mem file is different for this option as well, since it
8633 makes no sense of talking about DSEG lenght.
8635 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8637 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8638 in certain cases, e.g. when ROM assignment, patch provided
8639 from Albert den Haan.
8641 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8784 * src/mcs51/peephole.def,
8785 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
8786 (allows non-interrupt and interrupt code to safely compete for a resource

9664 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9665 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9666 type for bits was changed. It resulted in bit variables becoming

9684 A few small changes that speed up the peephole optimizer.
9688 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9690 Try to make the peephole optimizer smarter by maintaining
9691 an association between the assembly source code and the
9692 iCodes that originated them. Put this information to use
9693 with a new peephole rule condition "notVolatile" so that
9694 the rules can be aggressive yet still safe.
9699 * src/mcs51/peeph.def
9701 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9705 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9706 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9707 if the left or right operand symbols have the accuse flag set.
9709 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9711 Changed the type of the result of the ! (NOT) operator to char;
9712 previously it returned the same type as the source. This allows
9713 us to eliminate all the genFloatNot functions (all of its target
9714 implementations were very buggy) since !float can use the same
9717 * src/SDCCicode.c (ast2iCode): ! returns char

9726 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9727 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9728 during interrupts. Ensure WSAVE is located at a shared bank address.
9729 2. Fixed page selection in some places
9730 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9731 the registers name strings.
9732 4. Fixed "signed / unsigned compare" compiler warnings.
9733 5. The PIC port manages its own allocation of the general purpose
9734 registers, but makes no attempt to reuse them. As a result when
9735 compiling it soon runs out of general purpose registers. Some
9736 additional code was added to the files pcode.c and device.c to walk
9737 through the function call tree and rename the registers so that they
9747 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9748 genPlus() & genMinus() when the result is the same as left or right

9754 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9756 Made bitfield a distinct type from bit so that bitfields
9757 convert as per ANSI C and bits retain their traditional
9758 boolean style behaviour. Implemented bitfield support in
9766 * src/ds390/gen.c: bit v bitfield split
9767 * src/z80/gen.c: New support for bitfields
9768 * support/regression/tests/bitfields.c: reenabled z80,
9771 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9773 Rules 246.x, 247.x relate to bitfields, the others speed up
9774 access to xdata mapped I/O devices.
9776 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9778 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9780 Cleaned up genPackBits and genUnpackBits and added two helper

9782 for literal assignments in genPackBits (thanks to Frieder for
9788 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9790 Fixed bug #748310 (pointer to function type mishandled when the
9791 function name is omitted). Also fixed a SIGSEGV when a function
9792 attribute (reentrant, etc) is used on a non-function or on a
9793 function but misplaced before the parameter list.

9820 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9822 Made the constant following the "interrupt" keyword optional. If
9823 omitted, the function will not automatically be given an entry
9824 in the interrupt vector table (similar to #pragma NOIV, but
9825 less syntacticly kludgy). The interrupt number is also now
9826 range checked. Also fixed a bug in the high order bit example
9833 * support/Util/SDCCerr.c
9834 * support/Util/SDCCerr.h

9845 be re-activated by defining REDUCE_LITERALS)
9846 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
9847 unsigned, but are signed by default
9848 * src/SDCCval.c (constVal): rearranged
9849 * src/SDCCval.c (valMod): preliminary fix
9850 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9894 * src/SDCCval.c (valDiv, valMod): fixed signdness
9895 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
9896 signedness of modulo, left and right shift

10357 messages from optionsTable when a port is not configured, added
10358 support for the PIc16 port in the ports table, when executing
10359 the compiler with no port specified on command line, a default
10360 port is selected with the new macro DEFAULT_PORT which is
10361 defined in port.h, in setDefaultOptions() linkOptions is removed
10362 from initialization assignment, since now it is a set,
10363 parseCmdLine uses setParseWithComma for linkOptions, in
10364 linkEdit() linkOptions are accessed with new function indexSet()

11449 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
11450 * src/mcs51/main.c: removed {bindir}{sep} from aslink
11452 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11454 * in /sdcc/as/mcs51/ changed these files in order to create an
11455 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11456 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11457 following files to include the previous two files: aslink.dsp,
11458 Makefile.aslink, Makefile.bcc, and Makefile.in.
11460 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11461 .adb instead of .cdb
11463 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11465 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11466 value from option --iram-size.
11468 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11470 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11473 2002-09-18 <wiml AT hhhh.org>
11475 * SDCClrange.h: exposed setFromRange() and setToRange()
11476 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11477 packRegsForAccUse() (bug 542397)
11478 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11479 multiple times and emitting the fetch operations more than once
11480 added aopGetUsesAcc() function to allow binary operators to
11481 fetch their operands in the correct order; made genMinus() emit
11482 compact code for X = LITERAL - Y
11484 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11485 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11486 sprintf() in line 1267.
11488 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11489 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11492 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11493 Changes to aslink (All the changes are marked with 'JCF'):
11495 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11498 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11499 area BSEG. Also moves, if possible, the DATA area down into the internal
11500 ram so more space is available.
11502 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11505 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11506 not bytes. Function summary() which creates a memory usage summary
11507 file with extension .mem. Reports of overlaping stack and small stack
11508 size. If the space for the stack is less than 16 bytes aslink trows a
11511 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11512 the 8051. Option 'y' for memory summary output file.
11514 Changes to sdcc (All the changes are marked with 'JCF'):
11516 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11518 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11519 overlaying area for it (uses RegBankUsed[4]).
11521 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11522 bank zero as used by default. By default aslink locates the stack
11523 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11524 the creation of the .mem file. Delegates the allocation of data area
11525 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11526 the begining of the stack area to aslink.
11528 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11529 glue() in SDCCglue.c creates an area for it.
11531 2002-09-03 Borut Razem <borut.razem AT siol.net>
11532 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11533 sdcc/src/pic/glue.c:
11534 introduced atexit() handler for teporay files removal in case of
11535 errors, assertions, ...
11537 2002-08-29 Borut Razem <borut.razem AT siol.net>
11538 * sdcc/support/cpp2/auto-host_vc_in.h:
11539 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11540 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11541 Maybe there is a similar problem with BORLANDC? It should be checked!
11543 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11544 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11545 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11546 was not executed, and the compiler (cl) launched a warning:
11547 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11549 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11550 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11552 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11553 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11555 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11556 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,

11559 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11560 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11561 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11562 - added Release configuration in VS projects
11563 - review of compiler an linker options
11564 - VC .exe files are generated in bin_vc directory, not to interfere
11565 with binaries generated from other projects (cygwin, mingw, bcc ...)
11567 * sdcc/src/yacc.dsp: added
11569 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11570 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11571 and insert the version number definitions from .version

11575 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11576 added - genarate auto-host.h using auto-host_vc_in.h as template
11579 removed from CVS, generated automatically
11581 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11582 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11584 2002-08-11 Borut Razem <borut.razem AT siol.net>
11585 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11587 2002-08-10 Borut Razem <borut.razem AT siol.net>
11588 * src/SDCCmain.c (main):
11589 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11590 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11591 The consequence was that some temporary files were not removed.
11594 unification of code in functions tempfilename() and tempfile():
11595 function tempnam() is defined in Visual Studio 6.0 and .NET
11597 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11599 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11600 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11601 - removed compiler command line option /WX: Treats all warnings as errors
11602 - update a list of source files, included into the project
11604 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11605 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11606 changed project type to Generic Project so that can be correcly converted to VS.NET project
11608 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11610 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11612 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11614 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11615 added return 0 statements after assert() to make compiler happy
11617 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11618 added newline in the def file to keep MSC compiler satisfied
11620 * sdcc/src/z80/gen.c:
11621 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11622 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
