1582 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1584 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1585 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1587 One basic decision: e.g. src/clean.mk includes further files. In order
1588 to make this work there are two solutions:
1589 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1590 run configure on them. This way they can use
1591 'include $(srcdir)/port-clean.mk'
1592 - always include clean.mk by the Makefile at the same level. To avoid
1593 that `make clean` tries to include and build Makefile.dep the
1594 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1595 implemented, because now even `make uninstall` doesn't create
1596 Makefile.in. clean.mk could be eliminated by pasting it in
1599 * debugger/mcs51/Makefile.in: build own objects from library sources
1600 (SLIB, SDCC) in current directory
1602 * configure, configure.in: renamed --disable-device-lib-build in
1603 --disable-device-lib; added --enable-doc, the required tools are
1604 searched by configure; added result message; the toolchain for the
1605 belonging ports are now only built, if the port is enabled.
1607 * support/regression/*: all output is written in directory gen, because
1608 the fwk and ports directories don't livet in the build tree using vpath
1610 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1611 --disable-device-lib, added --enable-doc, added section VPATH
1613 * sim/ucsim/configure.in,
1614 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1615 z80 are enabled by default
1617 2006-04-24 Raphael Neider <rneider AT web.de>
1619 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1620 to config word, "pic14_"-prefixed some extern functions
1621 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1622 config word has been found
1623 * src/pic/device.h: added prototypes
1624 * src/pic/pcode.c: added "pic14_"-prefix where needed
1625 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
1627 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

1630 (pic14createInterruptVect): moved generating __config directives away

1640 registers that have not been assigned proper liveranges,
1641 fixes #1469504 and #1474602,
1642 (pCodeRegOptimizeRegUsage): fixed typo in comment

1888 implemented patch 1120823 Thanks to Willy De la Court (normal
1889 interrupts need an interrupt number now if they are made critical),
1890 and enabled nesting of critical functions though not for gbz80
1891 (genCritical, genEndCritical): added functions
1892 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1893 * src/z80/mappings.i: added "ei" to all mappings

1905 the left operand is shorter than the result (c* = lit-c* + int),
1907 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1910 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1912 * src/.version: increased version number to 2.5.5
1913 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1914 linking is done manually in pic16 port's _linkEdit,
1915 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1916 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1917 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1918 allocate asmop as AOP_ACC,
1919 (aopForRemat): added parameter 'bool result' in function declaration,
1920 (pic16_aopGet): return AOP_ACC when accessing WREG,
1921 (pic16_popGetTempReg): minor modification,
1922 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
1923 'pic16_allocWithIdx',

1930 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
1932 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1933 call to allocReg, not by manually allocating a new one,
1934 (pic16_assignRegisters): now before going through the register
1935 allocating functions mark all registers as free. This eliminates some
1936 side effects resulting from peephole parser done earlier in the backbone
1938 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

1996 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1997 which dumps before the function entry point a data byte which represents
1998 the number of the local variables used by the specified function, added
1999 'xinst' for initial support for Extended Instruction Support,
2000 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
2001 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
2002 port->fun_prefix anymore (may change later),
2003 (genFunction, genEndFunction): do not store/restore local registers for
2004 _main (this should take care the --main-return command line option in
2006 (genOr): removed some legacy pic-port instructions,
2007 * src/pic16/genarith.c (genAddLit): re-enabled old code because
2008 performing operations with SFR's causes data to be written more than
2009 once to each SFR. Perhaps SFRs should be handled in special cases...
2010 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
2012 * src/pic16/main.c (_process_pragma): stack bound checking did not take
2013 into account for stack starting position,

2017 (deassignLRs): *** perhaps the most important change, old 'for' code
2018 (commented out for reference), didn't account for some registers which
2019 were left marked 'not free' after a pointer operation. The change
2020 reduces register usage a lot in some cases

4312 2005-03-21 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4314 * src/SDCCcflow.c (dfNumCompare): committed the wrong version of this
4317 2005-03-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4319 * src/port.h (struct PORT),

4345 * src/SDCCBBlock.c (iCodeBreakDown, dumpEbbsToFileExt, eBBWithEntryLabel),
4346 * src/SDCCBBlock.h (struct ebbIndex): new struct that keeps two copies
4347 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
4348 immedDom() returning wrong block; probably fixes bug #1160833)
4350 2005-03-20 Borut Razem <borut.razem AT siol.net>
4352 * support/scripts/inc2h.pl: WIN32 port
4354 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
4356 * device/lib/makefile.in: added abs.c and labs.c
4358 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
4360 * device/include/stdint.h: added
4361 * device/lib/abs.c: added
4362 * device/lib/labs.c: added
4363 * device/include/stdlib.h: added abs() and labs() prototypes
4364 * device/lib/libsdcc.lib: added abs and labs
4365 * device/include/float.h,
4366 * device/lib/_fsmul.c,
4367 * device/lib/printf_fast.c,

4370 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4372 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
4375 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4377 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
4378 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
4380 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
4382 * device/lib/printf_large.c: removed inline assembly for portability and
4383 readability. Use printf_fast if speed or size are more important.
4384 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4385 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4387 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4389 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4390 prevent compiler warning
4392 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4394 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4395 moved to level 0 and declared as static. Also they are explicit
4396 placed in access bank. This was necessery because some times they
4397 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4398 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4399 optimizations. Currently only compare to unsigned char is implemented,
4400 * src/pic16/gen.c: added fReturnIdx array,
4401 * (struct resolvedIfx) is moved to gen.h and made public,
4402 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4403 * (aopForSym): added an optimization to directly store in stack of
4404 the operand of a SEND iCode,
4405 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4406 but as registers instead (AOP_REG) using the fReturnIdx array,
4407 * (pic16_freeAsmop): remove the freed register from the
4408 _G.sregsAlloc field,
4409 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4410 a compare of 'WREG',
4411 * (pic16_popGetTempRegCond): changed function prototype, now
4412 function takes also a bitVector argument v which holds the current
4413 set of registers that are allocated for stack access by aopForSym,
4414 registers allocated in aopForSym for accessing stack symbols are not
4415 any more part of the functions usedRegs field,
4416 * (genCall): some times aopOp is called for a stack variable to be
4417 send, aopForSym might perform the push, if this is true make sure
4418 that genCall doesn't push the variable twice by testing _G.resDirect,
4419 * (genFunction): changed testing for unspecified interrupt number
4420 from 256 to INTNO_UNSPEC,
4421 * modified selection scheme of frame pointer generation. Previously
4422 if function did use local registers a frame pointer was generated,
4423 now a frame pointer is generated only if function has arguments
4424 (that need PLUSW2 register access), or has stack arguments, or the
4425 compiler is not instructed to omit the frame pointer,
4426 * (genEndFunction): before restoring local registers that were saved
4427 in the function preamble, also restore the registers that *might*
4428 have been allocated for stack access,
4429 * (genRet): removed some old comments,
4430 * (genCmp, the active (RN's) version): added a call to the
4431 pic16_genCmp_special function to perform the compare with a more
4432 robust and optimized way,
4433 * (genInline): a feature has been added in inline code generation,
4434 which allows a wildcard variable substitution when writing inline
4435 assembly. Code is incomplete and experimental therefore undocumented,
4436 * (genCast): changed order of aopOp for result and right to allow
4437 aopForSym to directly load the result if possible,
4438 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4439 perform an optimized compare on some selected special occasions,
4440 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4441 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4442 generate an IVT any more,
4443 * src/pic16/main.c (pic16_optionsTable): added command line option
4445 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4446 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4448 * src/pic16/NOTES: Raphael Neider added in list of active developers
4449 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4450 jumptable_end to prevent bug #,
4451 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4452 inCond and outCond fields,
4453 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4454 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4455 turn off register spilling,
4456 * (packRegsForOneUse): synced with other ports' versions although it
4457 is not used currently,
4458 * (pic16_packRegisters): added an optimization while reading
4459 structure bitfields, some registers may be saved (malloc code is
4460 decreased by 80 bytes)
4462 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4464 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4465 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4466 this can be optimized more?
4468 2005-03-10 Raphael Neider <rneider AT web.de>
4470 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4471 genNearPointerGet): (hopefully) fixed access to bitfields via
4472 pointers (p->bitN = x; and x = p->bitN; failed)
4474 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
4476 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

4515 2005-02-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4517 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
4518 to keep the correct label reference count when adding/removing references
4519 to labels. A peephole file using this is appended to patch #1144962.

4661 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
4662 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
4663 this might fix SIGSEGVs on MinGW...
4664 * src/SDCCopt.c (killDeadCode): restored original behaviour
4665 (volatile operands might get thrown away though)
4667 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

4707 macro STACK_MODEL_{SMALL/LARGE} when compiling and assembling to
4708 reflect stack model used,
4709 * src/pic16/ralloc.c (pic16_allocDirReg): when operand is allocated

4721 the first pCode is used
4723 2005-01-22 Raphael Neider <rneider AT web.de>
4725 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): disabled optimization

4751 * (genUminus): rewritten to for efficiency
4752 * (genNearPointer[GS]et): enforce reloading of FSR0 (was still
4753 used uninitialized in some cases)
4754 * (genCast): upcasting a 16bit int to a 24bit GPOINTER may not
4755 copy the third byte from the int -- now assumes 0x80 (data memory)
4756 * src/pic16/genarith.c (pic16_genPlus): fixed bug when swapping
4757 operands (genAddLit expects the iCode's operands to swapped as
4758 well), fixed leftover bytes (crashed for short left operands)

5107 generated for switch statements. For now you need to set the
5108 environment variable SDCC_SJMP_JUMPTABLE to enable this.
5109 Now 4 algorithms for mcs51 jumptable generation are used:
5110 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
5111 addresses loaded pc-relative for up to 112 cases and stack-pushing
5112 target addresses loaded with offset from dptr for up to 256 cases.

5142 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
5144 * added libc directory. The current version of LibC contains string
5145 functions, ctype functions and macros and some functions of the
5146 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
5147 be extensively tested in the future. Standard disclaimer here.
5148 Library is not automatically build yet. But one can build it by
5149 invoking 'make' inside the libc directory.

5159 * (genUminusFloat): fixed for pic16, ported code from mcs51,
5160 * (pic16_storeForReturn): optimized return of 0,
5161 * (genCmp): experimental code for new genCmp which uses PIC18's
5162 special compare&skip instructions. Initial tests fail some times
5163 with variables grater than 1 byte in size, so new code is disabled,
5164 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5166 * (genCast): began a fix to optimize the casting of a bit to another
5167 bit, now assigning a bitfield to another bitfield will fail, sorry,
5168 * src/pic16/main.c: disabled the use of lr-support feature,
5169 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

5172 bits with offset (case PO_GPR_BIT),
5173 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
5175 * (isBankInstruction): modified to return 0 for no banking instruction,
5176 and 1 for banking instruction,
5177 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
5178 caused stop processing pCodes after a inline assembly block,
5179 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
5180 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
5181 registers when it shouldn't,
5182 * src/pic16/ralloc.c (allocReg): add preliminary support for

8190 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
8192 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
8193 loaded with the linker search paths (-L arguments) and the libraries
8194 to be linked with the current source (-l arguments). Changes
8195 currently will affect only the pic16 port.
8196 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8197 include path the port specific paths and port specific libraries,
8198 * gplink command now contains the $3 argument,
8199 * src/pic16/device.h,
8200 * src/pic16/device.c,: structure PIC_device is made public and
8201 renamed to PIC16_device, the same for variable Pics which is renamed

8216 Documenting changes from previous commits.
8217 * configure.in (version 1.56),
8218 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8219 when generating output files to configure the pic16 library,
8220 but now I've commented it out, since gputils aren't installed in the
8221 SF compile farm, so library won't compile
8223 * device/lib/Makefile.in (version 1.56): initially I've added in
8224 target 'all' the prerequestive 'model-pic16' so it compiled the
8225 pic16 library, but now I've commented it out for the same reasons
8227 * added targets 'model-pic16' and 'objects-pic16' to compile the
8229 * added target 'port-specific-objects-pic16' to handle the
8230 generated libraries and copy them into the build/ directory
8231 * added target 'clean-intermediate-pic16' to clean intermediate
8232 files into pic16 directory
8233 * in target 'installdirs' added line to create directory pic16 in
8234 the installation path
8236 * device/include/Makefile.in (version 1.11): in target 'install'
8237 added lines to copy all header files to installation path,
8238 * in target 'installdirs' added line create directory for pic16
8239 headers in the installation path

8254 * src/z80/main.c (_parseOptions): fixed the portmode= command line
8255 option so that it actually works. Made it specific to the z80, since
8256 the gbz80 doesn't have these kinds of I/O ports.
8258 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8260 * device/include/z180.h,

8284 via literal number. The symbol is placed in the corresponding
8285 position of the data ram
8286 * (pic16_dump_section): relocatable and absolute uninitialized
8287 data are now emitted in sorted order to reduce section naming,
8288 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
8289 weren't marked as being in the access bank,
8291 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
8293 Added portion of GNU PIC Library under the directory
8294 device/include/pic16 and device/lib/pic16. These files
8295 contain the declarations of SFRs for the PIC18Fxx2 devices.
8296 The directory is initialized via configure from toplevel.

8326 all over. Telling LaTeX to be less strict with word spacing
8327 to better keep the right margin. Changed some notes about
8328 maintainance of the ports in section 3.2.1 - is it OK like this?
8330 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

8370 * src/pic16/peeph.def: all peepholes with movff are commented out,
8371 because there is a problem in the pcode peep optimizer,
8372 * src/pic16/ralloc.c: the register allocator can now reuse local

8482 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8484 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
8485 (default behaviour).
8487 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8489 A python script to validate compiler diagnostic messages. It can be
8490 used to verify that sdcc complains about bad c source code and
8491 gives a good location of the error.
8492 * support/valdiag/Makefile,
8493 * support/valdiag/valdiag.py,
8494 * support/valdiag/tests/*

8511 Bug reported from Jesus Calvino-Fraga
8513 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8515 * sdcc.spec: updated
8516 * device/include/Makefile.in: don't install CVS directories
8517 * device/lib/Makefile.in: added removal of CVS directories after install
8518 * doc/Makefile: fixed install, added local_icons
8519 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8520 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8521 * src/ds390/gen.c (genRightShift): fixed bug #870788
8522 * src/SDCCast.c (decorateType): fixed bug #870781
8524 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8526 PIC16 port related changes:
8527 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8528 added variable stackPos,
8530 * gen.c: genCall, assignResultValue: added support for
8531 pushing/retrieving function parameters to/from stack,
8532 genFunction,genEndFunction: setup stack frame for the
8534 genAddrOf: will be changed according to bug 863624
8536 * added files genutils.c and genutils.h which contain gen*
8537 debugged and optimised functions extracted from gen.c
8539 * glue.c: added variable 'externs' which holds extern symbols,
8540 pic16emitRegularMap: is modified to properly handle relocatable
8541 symbols under the new scheme,
8542 pic16createInterruptVect: is modified
8543 pic16printPublics: is modified to emit 'global' assembler directives,
8544 added pic16_printExterns to print extern symbols,
8545 pic16glue: initializes stack/frame pointer in the beginning of
8546 the assembly output. Temporary hack, will be corrected later,
8547 because gplink yet does not support stack and SDCC does not
8548 yet support a type of crt0.o object to create the final binary.
8550 * Removed many lines that contain 8051 legacy code.
8551 * The code is finally placed under a 'code' directive.
8552 * Added port specific options.
8554 * _process_pragma: simplified since now we do not need *special*
8555 include file to define SFR registers. But a separate header
8556 will be needed. This will be developed later.
8557 * _pic16_parseOptions: added, parses port specific options:
8558 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8559 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8560 --preplace-udata-with=
8562 * _pic16_setDefaultOptions: modified to initialize section names,
8563 but hack is temporarly out of order since it needs improvement.
8564 * _pic16_genAssemblerPreamble: configuration words are emitted by
8565 their address instead of their name. This part is incomplete and
8566 supports only the 18Fxx2 devices. Other devices will emit an error
8567 during assembly since they do not contain the same set of config
8569 * _pic16_genIVT: is modified,
8571 * pcode.c: added definitions for some hardware registers that are needed
8573 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8574 All PCI entries are updated. Now LFSR is supported.
8575 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8576 * added pic16_newpCodeOpLit2 to support instructions with
8577 two literal arguments
8578 * pic16_pCode2str: corrected code that emits assembler instructions
8579 with two literal operands and those that have an access bit modifier
8580 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8581 this fixes a bug which caused some labels to be lost, when an
8582 assembler directive was added, i.e. banksel,
8583 * pic16_FixRegisterBanking: improved logic that causes the insertion
8585 * InlineFunction: functions that are called once, are not any more
8586 inlined. This can be a port option in the future,
8588 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8590 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8591 hold the corresponding uninitialized symbols,
8592 * pic16_allocProcessorRegister: registers have explicit marked the
8594 * pic16_allocInternalRegister: registers are explicit marked as
8596 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8597 processing list, so bit registers were lost,
8600 * ralloc.h: added field 'accessBank' and original symbol operand
8601 in register definition,
8602 * removed the field isMapped from register definition,
8604 ** Several functions have been removed from various sources:
8605 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8606 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8607 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8608 pic16_assignRelocatableRegisters
8610 ** others have been introduced:
8611 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8612 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8614 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8616 * support/scripts/inc2h.pl: changed definition of BIT_AT
8617 to emit 'sbit at' instead of 'bit at'. This was a request.
8619 PIC16 port related preliminary changes:
8620 * gen.c: prefixed function popRegFromString with
8621 pic16_ and all references to it corrected
8622 * pcode.c: all pic16_pc_* hardware registers prefixed
8623 with underscore (_),
8624 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8625 * ralloc.c: newReg(): when register is REG_SFR then
8626 set address to rIdx,
8627 pic16_allocProcessorRegister(): marks register wasUsed=0
8628 pic16_writeUsedRegs(): added a call to assign processor
8629 registers via pic16_assignFixedRegisters
8631 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8633 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8634 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8635 variables in unused register banks. Also the SSEG is placed
8636 wherever there is enough space for it, and IDATA can be anywhere
8637 in internal RAM. For now compile using -Wl-Y[stack_size].
8638 The mem file is different for this option as well, since it
8639 makes no sense of talking about DSEG lenght.
8641 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8643 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8644 in certain cases, e.g. when ROM assignment, patch provided
8645 from Albert den Haan.
8647 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8789 SDCC_NOGENRAMCLEAR to disable this.
8790 * src/mcs51/peephole.def,
8791 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
8792 (allows non-interrupt and interrupt code to safely compete for a resource
8793 without the non-interrupt code having to disable interrupts)
8795 2003-12-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8797 * src/SDCCicode.c (geniCodeAdd),

8812 2003-12-12 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8814 * src/mcs51/main.c(_mcs51_genRAMCLEAR): using r0 instead of r1/r2.

9670 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9671 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9672 type for bits was changed. It resulted in bit variables becoming
9673 global, which is not permitted in PIC 14 assembly output.

9690 A few small changes that speed up the peephole optimizer.
9694 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9696 Try to make the peephole optimizer smarter by maintaining
9697 an association between the assembly source code and the
9698 iCodes that originated them. Put this information to use
9699 with a new peephole rule condition "notVolatile" so that
9700 the rules can be aggressive yet still safe.
9705 * src/mcs51/peeph.def
9707 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9711 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9712 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9713 if the left or right operand symbols have the accuse flag set.
9715 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9717 Changed the type of the result of the ! (NOT) operator to char;
9718 previously it returned the same type as the source. This allows
9719 us to eliminate all the genFloatNot functions (all of its target
9720 implementations were very buggy) since !float can use the same
9723 * src/SDCCicode.c (ast2iCode): ! returns char

9732 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9733 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9734 during interrupts. Ensure WSAVE is located at a shared bank address.
9735 2. Fixed page selection in some places
9736 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9737 the registers name strings.
9738 4. Fixed "signed / unsigned compare" compiler warnings.
9739 5. The PIC port manages its own allocation of the general purpose
9740 registers, but makes no attempt to reuse them. As a result when
9741 compiling it soon runs out of general purpose registers. Some
9742 additional code was added to the files pcode.c and device.c to walk
9743 through the function call tree and rename the registers so that they
9753 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9754 genPlus() & genMinus() when the result is the same as left or right

9760 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9762 Made bitfield a distinct type from bit so that bitfields
9763 convert as per ANSI C and bits retain their traditional
9764 boolean style behaviour. Implemented bitfield support in
9772 * src/ds390/gen.c: bit v bitfield split
9773 * src/z80/gen.c: New support for bitfields
9774 * support/regression/tests/bitfields.c: reenabled z80,
9777 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9779 Rules 246.x, 247.x relate to bitfields, the others speed up
9780 access to xdata mapped I/O devices.
9782 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9784 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9786 Cleaned up genPackBits and genUnpackBits and added two helper
9787 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9788 for literal assignments in genPackBits (thanks to Frieder for
9794 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9796 Fixed bug #748310 (pointer to function type mishandled when the
9797 function name is omitted). Also fixed a SIGSEGV when a function
9798 attribute (reentrant, etc) is used on a non-function or on a
9799 function but misplaced before the parameter list.
9801 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9803 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
9804 * support/Util/SDCCerr.h,

9829 omitted, the function will not automatically be given an entry
9830 in the interrupt vector table (similar to #pragma NOIV, but
9831 less syntacticly kludgy). The interrupt number is also now
9832 range checked. Also fixed a bug in the high order bit example

10361 * src/SDCCmain.c: linkOptions is changed to set *,
10362 added if/endif conditional macros to remove options help
10363 messages from optionsTable when a port is not configured, added
10364 support for the PIc16 port in the ports table, when executing
10365 the compiler with no port specified on command line, a default
10366 port is selected with the new macro DEFAULT_PORT which is
10367 defined in port.h, in setDefaultOptions() linkOptions is removed
10368 from initialization assignment, since now it is a set,
10369 parseCmdLine uses setParseWithComma for linkOptions, in
10370 linkEdit() linkOptions are accessed with new function indexSet()
10371 which returns the i'th item of a set variable. See SDCCset.c, in
10372 linkEdit() when calling buildCmdLine(), added linkOptions as
10373 last argument. Now users can pass arguments to gplink via the
10374 -Wl option, main() uses pic16glue() to glue up pic16 programs

10386 * src/pic16/glue.c: commented out some error producing lines
10387 * src/pic16/main.c: __config directives are commented out to stop
10388 gpasm complaining and test the linkage with gplink, _linkCmd and
10389 _asmCmd changed to be more gplink and gpasm friendly
10390 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10391 produced an error when parsed, peep rule 12 is added to utilize
10392 movff, but it is commented out since the pCode does not support
10393 yet a command with 2 address arguments

11456 * src/mcs51/main.c: removed {bindir}{sep} from aslink
11458 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11460 * in /sdcc/as/mcs51/ changed these files in order to create an
11461 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11462 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11463 following files to include the previous two files: aslink.dsp,
11464 Makefile.aslink, Makefile.bcc, and Makefile.in.
11466 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11467 .adb instead of .cdb
11469 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11471 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11472 value from option --iram-size.
11474 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11476 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11479 2002-09-18 <wiml AT hhhh.org>
11481 * SDCClrange.h: exposed setFromRange() and setToRange()
11482 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11483 packRegsForAccUse() (bug 542397)
11484 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11485 multiple times and emitting the fetch operations more than once
11486 added aopGetUsesAcc() function to allow binary operators to
11487 fetch their operands in the correct order; made genMinus() emit
11488 compact code for X = LITERAL - Y
11490 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11491 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11492 sprintf() in line 1267.
11494 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11495 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11498 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11499 Changes to aslink (All the changes are marked with 'JCF'):
11501 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11504 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11505 area BSEG. Also moves, if possible, the DATA area down into the internal
11506 ram so more space is available.
11508 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11511 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11512 not bytes. Function summary() which creates a memory usage summary
11513 file with extension .mem. Reports of overlaping stack and small stack
11514 size. If the space for the stack is less than 16 bytes aslink trows a
11517 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11518 the 8051. Option 'y' for memory summary output file.
11520 Changes to sdcc (All the changes are marked with 'JCF'):
11522 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11524 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11525 overlaying area for it (uses RegBankUsed[4]).
11527 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11528 bank zero as used by default. By default aslink locates the stack
11529 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11530 the creation of the .mem file. Delegates the allocation of data area
11531 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11532 the begining of the stack area to aslink.
11534 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11535 glue() in SDCCglue.c creates an area for it.
11537 2002-09-03 Borut Razem <borut.razem AT siol.net>
11538 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11539 sdcc/src/pic/glue.c:
11540 introduced atexit() handler for teporay files removal in case of
11541 errors, assertions, ...
11543 2002-08-29 Borut Razem <borut.razem AT siol.net>
11544 * sdcc/support/cpp2/auto-host_vc_in.h:
11545 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11546 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11547 Maybe there is a similar problem with BORLANDC? It should be checked!
11549 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11550 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11551 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11552 was not executed, and the compiler (cl) launched a warning:
11553 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11555 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11556 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11558 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11559 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects

11566 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11567 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11568 - added Release configuration in VS projects
11569 - review of compiler an linker options
11570 - VC .exe files are generated in bin_vc directory, not to interfere
11571 with binaries generated from other projects (cygwin, mingw, bcc ...)
11573 * sdcc/src/yacc.dsp: added
11575 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11576 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11577 and insert the version number definitions from .version
11579 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11581 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11582 added - genarate auto-host.h using auto-host_vc_in.h as template
11585 removed from CVS, generated automatically
11587 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11588 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11590 2002-08-11 Borut Razem <borut.razem AT siol.net>
11591 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11593 2002-08-10 Borut Razem <borut.razem AT siol.net>
11594 * src/SDCCmain.c (main):
11595 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11596 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11597 The consequence was that some temporary files were not removed.
11600 unification of code in functions tempfilename() and tempfile():
11601 function tempnam() is defined in Visual Studio 6.0 and .NET
11603 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11605 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11606 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11607 - removed compiler command line option /WX: Treats all warnings as errors
11608 - update a list of source files, included into the project
11610 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,

11809 Previous fix was not good. basic blocks that have "break" or "return" are
11810 not really partof a loop , but live ranges used in these blocks should
