1973 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1975 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1976 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1978 One basic decision: e.g. src/clean.mk includes further files. In order
1979 to make this work there are two solutions:
1980 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1981 run configure on them. This way they can use
1982 'include $(srcdir)/port-clean.mk'
1983 - always include clean.mk by the Makefile at the same level. To avoid
1984 that `make clean` tries to include and build Makefile.dep the
1985 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1986 implemented, because now even `make uninstall` doesn't create
1987 Makefile.in. clean.mk could be eliminated by pasting it in
1990 * debugger/mcs51/Makefile.in: build own objects from library sources
1991 (SLIB, SDCC) in current directory
1993 * configure, configure.in: renamed --disable-device-lib-build in
1994 --disable-device-lib; added --enable-doc, the required tools are
1995 searched by configure; added result message; the toolchain for the
1996 belonging ports are now only built, if the port is enabled.
1998 * support/regression/*: all output is written in directory gen, because
1999 the fwk and ports directories don't livet in the build tree using vpath
2001 * doc/sdccman.lyx: renamed --disable-device-lib-build to
2002 --disable-device-lib, added --enable-doc, added section VPATH
2004 * sim/ucsim/configure.in,
2005 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
2006 z80 are enabled by default
2008 2006-04-24 Raphael Neider <rneider AT web.de>
2010 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
2011 to config word, "pic14_"-prefixed some extern functions
2012 (pic14_emitConfigWord): emit __config directive(s) if assignment to
2013 config word has been found
2014 * src/pic/device.h: added prototypes
2015 * src/pic/pcode.c: added "pic14_"-prefix where needed

2256 2006-04-05 Maarten Brock <sourceforge.brock AT dse.nl>
2258 * src/mcs51/gen.c (genCall): fixed bug 1457608
2260 2006-03-30 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

2265 2006-03-29 Maarten Brock <sourceforge.brock AT dse.nl>
2267 * src/SDCCpeeph.c (operandsLiteral): new, added,

2278 * src/z80/gen.c (genFunction, genEndFunction): fixed bug 1160666,
2279 implemented patch 1120823 Thanks to Willy De la Court (normal
2280 interrupts need an interrupt number now if they are made critical),
2281 and enabled nesting of critical functions though not for gbz80
2282 (genCritical, genEndCritical): added functions
2283 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
2284 * src/z80/mappings.i: added "ei" to all mappings
2286 2006-03-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
2288 * sim/ucsim/cmd.src/newcmdcl.h: applied patch fixing GCC 4.1 build
2289 submitted by the Debian SDCC maintainer Aurelien Jarno:
2290 "Credits goes to Martin Michlmayr, who rebuilt the whole Debian
2291 archive with gcc 4.1 on mips and wrote the patch"
2293 2006-03-16 Raphael Neider <rneider AT web.de>
2295 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
2296 the left operand is shorter than the result (c* = lit-c* + int),
2298 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
2301 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2303 * src/.version: increased version number to 2.5.5
2304 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
2305 linking is done manually in pic16 port's _linkEdit,
2306 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
2307 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
2308 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
2309 allocate asmop as AOP_ACC,
2310 (aopForRemat): added parameter 'bool result' in function declaration,
2311 (pic16_aopGet): return AOP_ACC when accessing WREG,
2312 (pic16_popGetTempReg): minor modification,
2313 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
2314 'pic16_allocWithIdx',
2315 (genPcall): removed ftype, usage of OP_SYM_TYPE asserted error when
2316 calling function in absolute addresses,
2317 (genAssign): take into account AOP_ACC asmop,
2318 * src/pic16/pcode.c (pic16_newpCodeOpReg): minor modifications,
2319 * src/pic16/pcoderegs.c: some debug functions and lines added,

2321 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
2323 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
2324 call to allocReg, not by manually allocating a new one,
2325 (pic16_assignRegisters): now before going through the register
2326 allocating functions mark all registers as free. This eliminates some
2327 side effects resulting from peephole parser done earlier in the backbone
2329 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
2331 * src/SDCCicode.c (geniCodeLogic),

2350 * src/mcs51/gen.c (newAsmop): set asmop.allocated to 1,
2351 (aopForSym, aopOp): increment asmop.allocated if reused,
2352 (freeAsmop): decrement asmop.allocated and check for zero instead of
2354 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
2355 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,
2356 genCmpLt, genAndOp, genOrOp, genAnd, genOr, genXor, genRRC, genRLC,

2379 2006-03-06 Borut Razem <borut.razem AT siol.net>
2381 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
2382 made the linker quiet
2384 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
2386 * src/pic16/gen.c (genPcall): fixed bug #1443644
2387 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
2388 which dumps before the function entry point a data byte which represents
2389 the number of the local variables used by the specified function, added
2390 'xinst' for initial support for Extended Instruction Support,
2391 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
2392 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
2393 port->fun_prefix anymore (may change later),
2394 (genFunction, genEndFunction): do not store/restore local registers for
2395 _main (this should take care the --main-return command line option in
2397 (genOr): removed some legacy pic-port instructions,
2398 * src/pic16/genarith.c (genAddLit): re-enabled old code because
2399 performing operations with SFR's causes data to be written more than
2400 once to each SFR. Perhaps SFRs should be handled in special cases...
2401 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
2403 * src/pic16/main.c (_process_pragma): stack bound checking did not take
2404 into account for stack starting position,
2405 (struct OPTIONS pic16_optionsTable): added command line argument
2406 --extended or -y for Extended Instruction Support,
2407 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
2408 (deassignLRs): *** perhaps the most important change, old 'for' code
2409 (commented out for reference), didn't account for some registers which
2410 were left marked 'not free' after a pointer operation. The change
2411 reduces register usage a lot in some cases
2413 2006-03-04 Borut Razem <borut.razem AT siol.net>
2415 * support/regression/ports/hc08/spec.mk: remove *.asm in traget

4703 2005-03-21 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4705 * src/SDCCcflow.c (dfNumCompare): committed the wrong version of this
4708 2005-03-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4710 * src/port.h (struct PORT),
4711 * src/avr/ralloc.c (avr_assignRegisters),
4713 * src/ds390/ralloc.c (ds390_assignRegisters),
4715 * src/hc08/ralloc.c (hc08_assignRegisters),

4736 * src/SDCCBBlock.c (iCodeBreakDown, dumpEbbsToFileExt, eBBWithEntryLabel),
4737 * src/SDCCBBlock.h (struct ebbIndex): new struct that keeps two copies
4738 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
4739 immedDom() returning wrong block; probably fixes bug #1160833)
4741 2005-03-20 Borut Razem <borut.razem AT siol.net>
4743 * support/scripts/inc2h.pl: WIN32 port
4745 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
4747 * device/lib/makefile.in: added abs.c and labs.c
4749 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
4751 * device/include/stdint.h: added
4752 * device/lib/abs.c: added
4753 * device/lib/labs.c: added
4754 * device/include/stdlib.h: added abs() and labs() prototypes
4755 * device/lib/libsdcc.lib: added abs and labs
4756 * device/include/float.h,
4757 * device/lib/_fsmul.c,
4758 * device/lib/printf_fast.c,

4761 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4763 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
4766 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4769 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
4771 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
4773 * device/lib/printf_large.c: removed inline assembly for portability and
4774 readability. Use printf_fast if speed or size are more important.
4775 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4776 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4778 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4780 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4781 prevent compiler warning
4783 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4785 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4786 moved to level 0 and declared as static. Also they are explicit
4787 placed in access bank. This was necessery because some times they
4788 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4789 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4790 optimizations. Currently only compare to unsigned char is implemented,
4791 * src/pic16/gen.c: added fReturnIdx array,
4792 * (struct resolvedIfx) is moved to gen.h and made public,
4793 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4794 * (aopForSym): added an optimization to directly store in stack of
4795 the operand of a SEND iCode,
4796 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4797 but as registers instead (AOP_REG) using the fReturnIdx array,
4798 * (pic16_freeAsmop): remove the freed register from the
4799 _G.sregsAlloc field,
4800 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4801 a compare of 'WREG',
4802 * (pic16_popGetTempRegCond): changed function prototype, now
4803 function takes also a bitVector argument v which holds the current
4804 set of registers that are allocated for stack access by aopForSym,
4805 registers allocated in aopForSym for accessing stack symbols are not
4806 any more part of the functions usedRegs field,
4807 * (genCall): some times aopOp is called for a stack variable to be
4808 send, aopForSym might perform the push, if this is true make sure
4809 that genCall doesn't push the variable twice by testing _G.resDirect,
4810 * (genFunction): changed testing for unspecified interrupt number
4811 from 256 to INTNO_UNSPEC,
4812 * modified selection scheme of frame pointer generation. Previously
4813 if function did use local registers a frame pointer was generated,
4814 now a frame pointer is generated only if function has arguments
4815 (that need PLUSW2 register access), or has stack arguments, or the
4816 compiler is not instructed to omit the frame pointer,
4817 * (genEndFunction): before restoring local registers that were saved
4818 in the function preamble, also restore the registers that *might*
4819 have been allocated for stack access,
4820 * (genRet): removed some old comments,
4821 * (genCmp, the active (RN's) version): added a call to the
4822 pic16_genCmp_special function to perform the compare with a more
4823 robust and optimized way,
4824 * (genInline): a feature has been added in inline code generation,
4825 which allows a wildcard variable substitution when writing inline
4826 assembly. Code is incomplete and experimental therefore undocumented,
4827 * (genCast): changed order of aopOp for result and right to allow
4828 aopForSym to directly load the result if possible,
4829 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4830 perform an optimized compare on some selected special occasions,
4831 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4832 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4833 generate an IVT any more,
4834 * src/pic16/main.c (pic16_optionsTable): added command line option
4836 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4837 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4839 * src/pic16/NOTES: Raphael Neider added in list of active developers
4840 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4841 jumptable_end to prevent bug #,
4842 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4843 inCond and outCond fields,
4844 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4845 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4846 turn off register spilling,
4847 * (packRegsForOneUse): synced with other ports' versions although it
4848 is not used currently,
4849 * (pic16_packRegisters): added an optimization while reading
4850 structure bitfields, some registers may be saved (malloc code is
4851 decreased by 80 bytes)
4853 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4855 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4856 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4857 this can be optimized more?
4859 2005-03-10 Raphael Neider <rneider AT web.de>
4861 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4862 genNearPointerGet): (hopefully) fixed access to bitfields via
4863 pointers (p->bitN = x; and x = p->bitN; failed)
4865 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
4867 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

4906 2005-02-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4908 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
4909 to keep the correct label reference count when adding/removing references
4910 to labels. A peephole file using this is appended to patch #1144962.

5052 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
5053 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
5054 this might fix SIGSEGVs on MinGW...
5055 * src/SDCCopt.c (killDeadCode): restored original behaviour
5056 (volatile operands might get thrown away though)
5058 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

5098 macro STACK_MODEL_{SMALL/LARGE} when compiling and assembling to
5099 reflect stack model used,
5100 * src/pic16/ralloc.c (pic16_allocDirReg): when operand is allocated

5112 the first pCode is used
5114 2005-01-22 Raphael Neider <rneider AT web.de>
5116 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): disabled optimization

5139 (MAX_PATH=256 truncates arguments leading to system halts when
5141 * src/pic16/gen.c (pic16_sameRegs): relaxed size criterion
5142 * (genUminus): rewritten to for efficiency
5143 * (genNearPointer[GS]et): enforce reloading of FSR0 (was still
5144 used uninitialized in some cases)
5145 * (genCast): upcasting a 16bit int to a 24bit GPOINTER may not
5146 copy the third byte from the int -- now assumes 0x80 (data memory)
5147 * src/pic16/genarith.c (pic16_genPlus): fixed bug when swapping
5148 operands (genAddLit expects the iCode's operands to swapped as
5149 well), fixed leftover bytes (crashed for short left operands)

5498 generated for switch statements. For now you need to set the
5499 environment variable SDCC_SJMP_JUMPTABLE to enable this.
5500 Now 4 algorithms for mcs51 jumptable generation are used:
5501 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

5533 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
5535 * added libc directory. The current version of LibC contains string
5536 functions, ctype functions and macros and some functions of the
5537 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
5538 be extensively tested in the future. Standard disclaimer here.
5539 Library is not automatically build yet. But one can build it by
5540 invoking 'make' inside the libc directory.

5550 * (genUminusFloat): fixed for pic16, ported code from mcs51,
5551 * (pic16_storeForReturn): optimized return of 0,
5552 * (genCmp): experimental code for new genCmp which uses PIC18's
5553 special compare&skip instructions. Initial tests fail some times
5554 with variables grater than 1 byte in size, so new code is disabled,
5555 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5557 * (genCast): began a fix to optimize the casting of a bit to another
5558 bit, now assigning a bitfield to another bitfield will fail, sorry,
5559 * src/pic16/main.c: disabled the use of lr-support feature,
5560 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

5563 bits with offset (case PO_GPR_BIT),
5564 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
5566 * (isBankInstruction): modified to return 0 for no banking instruction,
5567 and 1 for banking instruction,
5568 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
5569 caused stop processing pCodes after a inline assembly block,
5570 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
5571 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
5572 registers when it shouldn't,
5573 * src/pic16/ralloc.c (allocReg): add preliminary support for

8581 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
8583 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
8584 loaded with the linker search paths (-L arguments) and the libraries
8585 to be linked with the current source (-l arguments). Changes
8586 currently will affect only the pic16 port.
8587 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8588 include path the port specific paths and port specific libraries,
8589 * gplink command now contains the $3 argument,
8590 * src/pic16/device.h,
8591 * src/pic16/device.c,: structure PIC_device is made public and
8592 renamed to PIC16_device, the same for variable Pics which is renamed

8607 Documenting changes from previous commits.
8608 * configure.in (version 1.56),
8609 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8610 when generating output files to configure the pic16 library,
8611 but now I've commented it out, since gputils aren't installed in the
8612 SF compile farm, so library won't compile
8614 * device/lib/Makefile.in (version 1.56): initially I've added in
8615 target 'all' the prerequestive 'model-pic16' so it compiled the
8616 pic16 library, but now I've commented it out for the same reasons
8618 * added targets 'model-pic16' and 'objects-pic16' to compile the
8620 * added target 'port-specific-objects-pic16' to handle the
8621 generated libraries and copy them into the build/ directory
8622 * added target 'clean-intermediate-pic16' to clean intermediate
8623 files into pic16 directory
8624 * in target 'installdirs' added line to create directory pic16 in
8625 the installation path
8627 * device/include/Makefile.in (version 1.11): in target 'install'
8628 added lines to copy all header files to installation path,
8629 * in target 'installdirs' added line create directory for pic16
8630 headers in the installation path

8645 * src/z80/main.c (_parseOptions): fixed the portmode= command line
8646 option so that it actually works. Made it specific to the z80, since
8647 the gbz80 doesn't have these kinds of I/O ports.
8649 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8651 * device/include/z180.h,

8675 via literal number. The symbol is placed in the corresponding
8676 position of the data ram
8677 * (pic16_dump_section): relocatable and absolute uninitialized
8678 data are now emitted in sorted order to reduce section naming,
8679 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
8680 weren't marked as being in the access bank,
8682 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
8684 Added portion of GNU PIC Library under the directory
8685 device/include/pic16 and device/lib/pic16. These files
8686 contain the declarations of SFRs for the PIC18Fxx2 devices.
8687 The directory is initialized via configure from toplevel.

8761 * src/pic16/peeph.def: all peepholes with movff are commented out,
8762 because there is a problem in the pcode peep optimizer,
8763 * src/pic16/ralloc.c: the register allocator can now reuse local

8873 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8875 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
8876 (default behaviour).
8878 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8880 A python script to validate compiler diagnostic messages. It can be
8881 used to verify that sdcc complains about bad c source code and
8882 gives a good location of the error.
8883 * support/valdiag/Makefile,
8884 * support/valdiag/valdiag.py,
8885 * support/valdiag/tests/*

8902 Bug reported from Jesus Calvino-Fraga
8904 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8906 * sdcc.spec: updated
8907 * device/include/Makefile.in: don't install CVS directories
8908 * device/lib/Makefile.in: added removal of CVS directories after install
8909 * doc/Makefile: fixed install, added local_icons
8910 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8911 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8912 * src/ds390/gen.c (genRightShift): fixed bug #870788
8913 * src/SDCCast.c (decorateType): fixed bug #870781
8915 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8917 PIC16 port related changes:
8918 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8919 added variable stackPos,
8921 * gen.c: genCall, assignResultValue: added support for
8922 pushing/retrieving function parameters to/from stack,
8923 genFunction,genEndFunction: setup stack frame for the
8925 genAddrOf: will be changed according to bug 863624
8927 * added files genutils.c and genutils.h which contain gen*
8928 debugged and optimised functions extracted from gen.c
8930 * glue.c: added variable 'externs' which holds extern symbols,
8931 pic16emitRegularMap: is modified to properly handle relocatable
8932 symbols under the new scheme,
8933 pic16createInterruptVect: is modified
8934 pic16printPublics: is modified to emit 'global' assembler directives,
8935 added pic16_printExterns to print extern symbols,
8936 pic16glue: initializes stack/frame pointer in the beginning of
8937 the assembly output. Temporary hack, will be corrected later,
8938 because gplink yet does not support stack and SDCC does not
8939 yet support a type of crt0.o object to create the final binary.
8941 * Removed many lines that contain 8051 legacy code.
8942 * The code is finally placed under a 'code' directive.
8943 * Added port specific options.
8945 * _process_pragma: simplified since now we do not need *special*
8946 include file to define SFR registers. But a separate header
8947 will be needed. This will be developed later.
8948 * _pic16_parseOptions: added, parses port specific options:
8949 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8950 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8951 --preplace-udata-with=
8953 * _pic16_setDefaultOptions: modified to initialize section names,
8954 but hack is temporarly out of order since it needs improvement.
8955 * _pic16_genAssemblerPreamble: configuration words are emitted by
8956 their address instead of their name. This part is incomplete and
8957 supports only the 18Fxx2 devices. Other devices will emit an error
8958 during assembly since they do not contain the same set of config
8960 * _pic16_genIVT: is modified,
8962 * pcode.c: added definitions for some hardware registers that are needed
8964 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8965 All PCI entries are updated. Now LFSR is supported.
8966 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8967 * added pic16_newpCodeOpLit2 to support instructions with
8968 two literal arguments
8969 * pic16_pCode2str: corrected code that emits assembler instructions
8970 with two literal operands and those that have an access bit modifier
8971 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8972 this fixes a bug which caused some labels to be lost, when an
8973 assembler directive was added, i.e. banksel,
8974 * pic16_FixRegisterBanking: improved logic that causes the insertion
8976 * InlineFunction: functions that are called once, are not any more
8977 inlined. This can be a port option in the future,
8979 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8981 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8982 hold the corresponding uninitialized symbols,
8983 * pic16_allocProcessorRegister: registers have explicit marked the
8985 * pic16_allocInternalRegister: registers are explicit marked as
8987 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8988 processing list, so bit registers were lost,
8991 * ralloc.h: added field 'accessBank' and original symbol operand
8992 in register definition,
8993 * removed the field isMapped from register definition,
8995 ** Several functions have been removed from various sources:
8996 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8997 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8998 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8999 pic16_assignRelocatableRegisters
9001 ** others have been introduced:
9002 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
9003 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
9005 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
9007 * support/scripts/inc2h.pl: changed definition of BIT_AT
9008 to emit 'sbit at' instead of 'bit at'. This was a request.
9010 PIC16 port related preliminary changes:
9011 * gen.c: prefixed function popRegFromString with
9012 pic16_ and all references to it corrected
9013 * pcode.c: all pic16_pc_* hardware registers prefixed
9014 with underscore (_),
9015 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
9016 * ralloc.c: newReg(): when register is REG_SFR then
9017 set address to rIdx,
9018 pic16_allocProcessorRegister(): marks register wasUsed=0
9019 pic16_writeUsedRegs(): added a call to assign processor
9020 registers via pic16_assignFixedRegisters
9022 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9024 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
9025 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
9026 variables in unused register banks. Also the SSEG is placed
9027 wherever there is enough space for it, and IDATA can be anywhere
9028 in internal RAM. For now compile using -Wl-Y[stack_size].
9029 The mem file is different for this option as well, since it
9030 makes no sense of talking about DSEG lenght.
9032 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
9034 * src/SDCClrange.c: fixed bug 869095 that caused segfault
9035 in certain cases, e.g. when ROM assignment, patch provided
9036 from Albert den Haan.
9038 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

9180 SDCC_NOGENRAMCLEAR to disable this.
9181 * src/mcs51/peephole.def,
9182 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
9183 (allows non-interrupt and interrupt code to safely compete for a resource
9184 without the non-interrupt code having to disable interrupts)
9186 2003-12-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9188 * src/SDCCicode.c (geniCodeAdd),

9208 2003-12-11 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9210 * src/z80/ralloc.c: set DISABLE_PACK_HL = 1 as a temporary fix to bug #855165

9281 it breaks with bitfields, extern declarations, and gcse analysis.
9282 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
9283 could be assigned through a pointer, so don't complain.

10061 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10062 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
10063 type for bits was changed. It resulted in bit variables becoming
10064 global, which is not permitted in PIC 14 assembly output.
10066 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10068 * doc/sdccman.lyx: various additions and updates. Rearranged sections

10081 A few small changes that speed up the peephole optimizer.
10085 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10087 Try to make the peephole optimizer smarter by maintaining
10088 an association between the assembly source code and the
10089 iCodes that originated them. Put this information to use
10090 with a new peephole rule condition "notVolatile" so that
10091 the rules can be aggressive yet still safe.
10096 * src/mcs51/peeph.def
10098 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10102 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
10103 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
10104 if the left or right operand symbols have the accuse flag set.
10106 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10108 Changed the type of the result of the ! (NOT) operator to char;
10109 previously it returned the same type as the source. This allows
10110 us to eliminate all the genFloatNot functions (all of its target
10111 implementations were very buggy) since !float can use the same

10123 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10124 1. Interrupt would not compile properly. Ensure PCLATH register is saved
10125 during interrupts. Ensure WSAVE is located at a shared bank address.
10126 2. Fixed page selection in some places
10127 3. Fixed BTFSS/C to where necessary use registers directly and not simply
10128 the registers name strings.
10129 4. Fixed "signed / unsigned compare" compiler warnings.
10130 5. The PIC port manages its own allocation of the general purpose
10131 registers, but makes no attempt to reuse them. As a result when
10132 compiling it soon runs out of general purpose registers. Some
10133 additional code was added to the files pcode.c and device.c to walk
10134 through the function call tree and rename the registers so that they
10144 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
10145 genPlus() & genMinus() when the result is the same as left or right
10147 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

10151 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10153 Made bitfield a distinct type from bit so that bitfields
10154 convert as per ANSI C and bits retain their traditional
10155 boolean style behaviour. Implemented bitfield support in
10163 * src/ds390/gen.c: bit v bitfield split
10164 * src/z80/gen.c: New support for bitfields
10165 * support/regression/tests/bitfields.c: reenabled z80,
10168 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10170 Rules 246.x, 247.x relate to bitfields, the others speed up
10171 access to xdata mapped I/O devices.
10173 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
10175 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10177 Cleaned up genPackBits and genUnpackBits and added two helper
10178 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
10179 for literal assignments in genPackBits (thanks to Frieder for
10185 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10187 Fixed bug #748310 (pointer to function type mishandled when the
10188 function name is omitted). Also fixed a SIGSEGV when a function
10189 attribute (reentrant, etc) is used on a non-function or on a
10190 function but misplaced before the parameter list.

10220 omitted, the function will not automatically be given an entry
10221 in the interrupt vector table (similar to #pragma NOIV, but

10727 * src/pic16/pcodeflow.c: Cleaned warnings
10728 * src/pic16/pcoderegs.c: Cleaned warnings
10730 2003-05-19 Scott Dattalo <scott AT dattalo.com>
10732 * src/pic16/pcode.c: Cleaned warnings
10733 * src/pic16/pcodepeep.c: Cleaned warnings
10734 * src/pic16/ralloc.c: Cleaned warnings

10741 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
10743 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
10744 it can be defined with CFLAGS when running configure
10745 * src/SDCCmain.c: fixed compiling + linking with object files
10747 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
10749 * configure.in: configure for pic16 port,
10750 added --disable-pic16-port
10751 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
10752 * src/SDCCmain.c: linkOptions is changed to set *,
10753 added if/endif conditional macros to remove options help
10754 messages from optionsTable when a port is not configured, added
10755 support for the PIc16 port in the ports table, when executing
10756 the compiler with no port specified on command line, a default
10757 port is selected with the new macro DEFAULT_PORT which is
10758 defined in port.h, in setDefaultOptions() linkOptions is removed
10759 from initialization assignment, since now it is a set,
10760 parseCmdLine uses setParseWithComma for linkOptions, in
10761 linkEdit() linkOptions are accessed with new function indexSet()
10762 which returns the i'th item of a set variable. See SDCCset.c, in
10763 linkEdit() when calling buildCmdLine(), added linkOptions as
10764 last argument. Now users can pass arguments to gplink via the
10765 -Wl option, main() uses pic16glue() to glue up pic16 programs
10766 * src/SDCCpeeph.c: various changes to support pic16
10767 * src/SDCCset.c: added function void *indexSet(set *, int) to
10768 return the i'th item of the set
10769 * src/SDCCset.h: added function prototype for indexSet()
10770 * src/SDCCsymt.c: in checkSClass(), added support for PIC16
10771 * src/clean.mk: added pic16 in CLEANALLPORTS variable

10773 added macro DEFAULT_PORT
10774 * src/pic/main.c: corrected arguments of gplnk in _linkCmd
10775 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
10777 * src/pic16/glue.c: commented out some error producing lines
10778 * src/pic16/main.c: __config directives are commented out to stop
10779 gpasm complaining and test the linkage with gplink, _linkCmd and
10780 _asmCmd changed to be more gplink and gpasm friendly
10781 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10782 produced an error when parsed, peep rule 12 is added to utilize
10783 movff, but it is commented out since the pCode does not support
10784 yet a command with 2 address arguments
10786 2003-05-18 <johan AT balder>
10788 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

11849 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11851 * in /sdcc/as/mcs51/ changed these files in order to create an
11852 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11853 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11854 following files to include the previous two files: aslink.dsp,
11855 Makefile.aslink, Makefile.bcc, and Makefile.in.
11857 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11858 .adb instead of .cdb
11860 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11862 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11863 value from option --iram-size.
11865 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11867 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11870 2002-09-18 <wiml AT hhhh.org>
11872 * SDCClrange.h: exposed setFromRange() and setToRange()
11873 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11874 packRegsForAccUse() (bug 542397)
11875 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11876 multiple times and emitting the fetch operations more than once
11877 added aopGetUsesAcc() function to allow binary operators to
11878 fetch their operands in the correct order; made genMinus() emit
11879 compact code for X = LITERAL - Y
11881 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11882 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11883 sprintf() in line 1267.
11885 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11886 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11889 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11890 Changes to aslink (All the changes are marked with 'JCF'):
11892 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11895 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11896 area BSEG. Also moves, if possible, the DATA area down into the internal
11897 ram so more space is available.
11899 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11902 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11903 not bytes. Function summary() which creates a memory usage summary
11904 file with extension .mem. Reports of overlaping stack and small stack
11905 size. If the space for the stack is less than 16 bytes aslink trows a
11908 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11909 the 8051. Option 'y' for memory summary output file.
11911 Changes to sdcc (All the changes are marked with 'JCF'):
11913 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11915 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11916 overlaying area for it (uses RegBankUsed[4]).
11918 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11919 bank zero as used by default. By default aslink locates the stack
11920 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11921 the creation of the .mem file. Delegates the allocation of data area
11922 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11923 the begining of the stack area to aslink.
11925 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11926 glue() in SDCCglue.c creates an area for it.
11928 2002-09-03 Borut Razem <borut.razem AT siol.net>
11929 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11930 sdcc/src/pic/glue.c:
11931 introduced atexit() handler for teporay files removal in case of
11932 errors, assertions, ...
11934 2002-08-29 Borut Razem <borut.razem AT siol.net>
11935 * sdcc/support/cpp2/auto-host_vc_in.h:
11936 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11937 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11938 Maybe there is a similar problem with BORLANDC? It should be checked!
11940 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11941 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11942 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11943 was not executed, and the compiler (cl) launched a warning:
11944 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11946 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11947 * src/SDCCglue.c (printIvalArray): iterative calculation of array length

11959 - added Release configuration in VS projects
11960 - review of compiler an linker options
11961 - VC .exe files are generated in bin_vc directory, not to interfere
11962 with binaries generated from other projects (cygwin, mingw, bcc ...)
11964 * sdcc/src/yacc.dsp: added
11966 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11967 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11968 and insert the version number definitions from .version
11970 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11972 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11973 added - genarate auto-host.h using auto-host_vc_in.h as template
11976 removed from CVS, generated automatically
11978 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11979 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11981 2002-08-11 Borut Razem <borut.razem AT siol.net>
11982 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11984 2002-08-10 Borut Razem <borut.razem AT siol.net>
11985 * src/SDCCmain.c (main):
11986 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11987 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11988 The consequence was that some temporary files were not removed.
11991 unification of code in functions tempfilename() and tempfile():
11992 function tempnam() is defined in Visual Studio 6.0 and .NET
11994 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11996 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11997 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11998 - removed compiler command line option /WX: Treats all warnings as errors
11999 - update a list of source files, included into the project
12001 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12002 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
12003 changed project type to Generic Project so that can be correcly converted to VS.NET project
12005 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
12007 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
12009 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
12011 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
12012 added return 0 statements after assert() to make compiler happy
12014 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
12015 added newline in the def file to keep MSC compiler satisfied
12017 * sdcc/src/z80/gen.c:
12018 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
12019 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
12020 - solved MSC error in function aopDump()
12022 * sdcc_vc.h: define PREFIX as "\\sdcc"
12024 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

12079 Compiler generated registers for interrupt context saving
12080 were not getting allocated.
12082 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>

12199 * sdcc/src/SDCCloop.c:
12200 Previous fix was not good. basic blocks that have "break" or "return" are
12201 not really partof a loop , but live ranges used in these blocks should
