3 * src/pic/device.c (create_pic,ram_map): add memRange entries to PIC
4 (pic14_getSharebankSize, pic14_getSharebankAddress): replaced with
5 (pic14_hasSharebank,pic14_isShared,pic14_allRAMShared,
6 pic14_getSharedStack): NEW, evaluate the memRange entries to locate
7 a sharebank, use a non-shared bank for the stack if none available
8 * src/pic/device.h (struct memRange): added linked list next field,
9 added prototypes for above functions
10 * src/pic/ralloc.c (initStack): handle shared and banked stacks,
11 (typeRegWithIdx): accept fixed and unfixed stack registers
12 * src/pic/pcode.c (pCodeInitRegisters): use new functions to create
13 the stack, handle shared and banked stack (except for WSAVE),
14 (insertBankSel): removed useless optimization (will never fire),
15 (FixRegisterBanking): added optimization for devices with only one
16 possibly aliased bank of memory, like 16f84
17 * src/pic/glue.c (pic14_constructAbsMap): back to udata_ovr, as some
18 devices have no SHAREBANK in the linker script

30 genRightShift): fixed bug with non-constant bit shift stored to
31 a volatile result (SF Open Discussion forum thread #1616749).
32 Single byte case is not yet optimized.

1935 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1937 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1938 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1940 One basic decision: e.g. src/clean.mk includes further files. In order
1941 to make this work there are two solutions:
1942 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1943 run configure on them. This way they can use
1944 'include $(srcdir)/port-clean.mk'
1945 - always include clean.mk by the Makefile at the same level. To avoid
1946 that `make clean` tries to include and build Makefile.dep the
1947 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1948 implemented, because now even `make uninstall` doesn't create
1949 Makefile.in. clean.mk could be eliminated by pasting it in
1952 * debugger/mcs51/Makefile.in: build own objects from library sources
1953 (SLIB, SDCC) in current directory
1955 * configure, configure.in: renamed --disable-device-lib-build in
1956 --disable-device-lib; added --enable-doc, the required tools are
1957 searched by configure; added result message; the toolchain for the
1958 belonging ports are now only built, if the port is enabled.
1960 * support/regression/*: all output is written in directory gen, because
1961 the fwk and ports directories don't livet in the build tree using vpath
1963 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1964 --disable-device-lib, added --enable-doc, added section VPATH
1966 * sim/ucsim/configure.in,
1967 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1968 z80 are enabled by default
1970 2006-04-24 Raphael Neider <rneider AT web.de>
1972 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1973 to config word, "pic14_"-prefixed some extern functions
1974 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1975 config word has been found
1976 * src/pic/device.h: added prototypes
1977 * src/pic/pcode.c: added "pic14_"-prefix where needed
1978 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
1980 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

1995 (pCodeRegOptimizeRegUsage): fixed typo in comment

2212 2006-04-05 Maarten Brock <sourceforge.brock AT dse.nl>
2214 * src/SDCCpeeph.c (initPeepHole): implemented RFE 1460196, when both

2218 2006-04-05 Maarten Brock <sourceforge.brock AT dse.nl>
2220 * src/mcs51/gen.c (genCall): fixed bug 1457608
2222 2006-03-30 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
2224 * doc/sdccman.lyx: reverted to version 1.129 of december as my latest

2227 2006-03-29 Maarten Brock <sourceforge.brock AT dse.nl>
2229 * src/SDCCpeeph.c (operandsLiteral): new, added,

2240 * src/z80/gen.c (genFunction, genEndFunction): fixed bug 1160666,
2241 implemented patch 1120823 Thanks to Willy De la Court (normal
2242 interrupts need an interrupt number now if they are made critical),
2243 and enabled nesting of critical functions though not for gbz80
2244 (genCritical, genEndCritical): added functions
2245 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
2246 * src/z80/mappings.i: added "ei" to all mappings
2248 2006-03-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
2250 * sim/ucsim/cmd.src/newcmdcl.h: applied patch fixing GCC 4.1 build
2251 submitted by the Debian SDCC maintainer Aurelien Jarno:
2252 "Credits goes to Martin Michlmayr, who rebuilt the whole Debian
2253 archive with gcc 4.1 on mips and wrote the patch"
2255 2006-03-16 Raphael Neider <rneider AT web.de>
2257 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
2258 the left operand is shorter than the result (c* = lit-c* + int),
2260 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
2263 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2265 * src/.version: increased version number to 2.5.5
2266 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
2267 linking is done manually in pic16 port's _linkEdit,
2268 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
2269 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
2270 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
2271 allocate asmop as AOP_ACC,
2272 (aopForRemat): added parameter 'bool result' in function declaration,
2273 (pic16_aopGet): return AOP_ACC when accessing WREG,
2274 (pic16_popGetTempReg): minor modification,
2275 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
2276 'pic16_allocWithIdx',
2277 (genPcall): removed ftype, usage of OP_SYM_TYPE asserted error when
2278 calling function in absolute addresses,
2279 (genAssign): take into account AOP_ACC asmop,
2280 * src/pic16/pcode.c (pic16_newpCodeOpReg): minor modifications,
2281 * src/pic16/pcoderegs.c: some debug functions and lines added,
2282 * src/pic16/ralloc.c (decodeRegType): added but commented out,
2283 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
2285 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
2286 call to allocReg, not by manually allocating a new one,
2287 (pic16_assignRegisters): now before going through the register
2288 allocating functions mark all registers as free. This eliminates some
2289 side effects resulting from peephole parser done earlier in the backbone
2291 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
2293 * src/SDCCicode.c (geniCodeLogic),

2311 * src/mcs51/gen.h: changed asmop.freed:1 to asmop.allocated for tracking
2312 * src/mcs51/gen.c (newAsmop): set asmop.allocated to 1,
2313 (aopForSym, aopOp): increment asmop.allocated if reused,
2314 (freeAsmop): decrement asmop.allocated and check for zero instead of
2316 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
2317 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,
2318 genCmpLt, genAndOp, genOrOp, genAnd, genOr, genXor, genRRC, genRLC,

2341 2006-03-06 Borut Razem <borut.razem AT siol.net>
2343 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
2344 made the linker quiet
2346 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
2348 * src/pic16/gen.c (genPcall): fixed bug #1443644
2349 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
2350 which dumps before the function entry point a data byte which represents
2351 the number of the local variables used by the specified function, added
2352 'xinst' for initial support for Extended Instruction Support,
2353 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
2354 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
2355 port->fun_prefix anymore (may change later),
2356 (genFunction, genEndFunction): do not store/restore local registers for
2357 _main (this should take care the --main-return command line option in
2359 (genOr): removed some legacy pic-port instructions,
2360 * src/pic16/genarith.c (genAddLit): re-enabled old code because
2361 performing operations with SFR's causes data to be written more than
2362 once to each SFR. Perhaps SFRs should be handled in special cases...
2363 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
2365 * src/pic16/main.c (_process_pragma): stack bound checking did not take
2366 into account for stack starting position,
2367 (struct OPTIONS pic16_optionsTable): added command line argument
2368 --extended or -y for Extended Instruction Support,
2369 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
2370 (deassignLRs): *** perhaps the most important change, old 'for' code
2371 (commented out for reference), didn't account for some registers which
2372 were left marked 'not free' after a pointer operation. The change
2373 reduces register usage a lot in some cases
2375 2006-03-04 Borut Razem <borut.razem AT siol.net>
2377 * support/regression/ports/hc08/spec.mk: remove *.asm in traget

4707 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
4709 * device/lib/makefile.in: added abs.c and labs.c
4711 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
4713 * device/include/stdint.h: added
4714 * device/lib/abs.c: added
4715 * device/lib/labs.c: added
4716 * device/include/stdlib.h: added abs() and labs() prototypes
4717 * device/lib/libsdcc.lib: added abs and labs
4718 * device/include/float.h,
4719 * device/lib/_fsmul.c,
4720 * device/lib/printf_fast.c,
4721 * device/lib/printf_tiny.c: updated comments
4723 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4725 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
4728 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4730 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
4731 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
4733 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
4735 * device/lib/printf_large.c: removed inline assembly for portability and
4736 readability. Use printf_fast if speed or size are more important.
4737 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4738 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4740 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4742 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4743 prevent compiler warning
4745 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4747 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4748 moved to level 0 and declared as static. Also they are explicit
4749 placed in access bank. This was necessery because some times they
4750 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4751 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4752 optimizations. Currently only compare to unsigned char is implemented,
4753 * src/pic16/gen.c: added fReturnIdx array,
4754 * (struct resolvedIfx) is moved to gen.h and made public,
4755 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4756 * (aopForSym): added an optimization to directly store in stack of
4757 the operand of a SEND iCode,
4758 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4759 but as registers instead (AOP_REG) using the fReturnIdx array,
4760 * (pic16_freeAsmop): remove the freed register from the
4761 _G.sregsAlloc field,
4762 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4763 a compare of 'WREG',
4764 * (pic16_popGetTempRegCond): changed function prototype, now
4765 function takes also a bitVector argument v which holds the current
4766 set of registers that are allocated for stack access by aopForSym,
4767 registers allocated in aopForSym for accessing stack symbols are not
4768 any more part of the functions usedRegs field,
4769 * (genCall): some times aopOp is called for a stack variable to be
4770 send, aopForSym might perform the push, if this is true make sure
4771 that genCall doesn't push the variable twice by testing _G.resDirect,
4772 * (genFunction): changed testing for unspecified interrupt number
4773 from 256 to INTNO_UNSPEC,
4774 * modified selection scheme of frame pointer generation. Previously
4775 if function did use local registers a frame pointer was generated,
4776 now a frame pointer is generated only if function has arguments
4777 (that need PLUSW2 register access), or has stack arguments, or the
4778 compiler is not instructed to omit the frame pointer,
4779 * (genEndFunction): before restoring local registers that were saved
4780 in the function preamble, also restore the registers that *might*
4781 have been allocated for stack access,
4782 * (genRet): removed some old comments,
4783 * (genCmp, the active (RN's) version): added a call to the
4784 pic16_genCmp_special function to perform the compare with a more
4785 robust and optimized way,
4786 * (genInline): a feature has been added in inline code generation,
4787 which allows a wildcard variable substitution when writing inline
4788 assembly. Code is incomplete and experimental therefore undocumented,
4789 * (genCast): changed order of aopOp for result and right to allow
4790 aopForSym to directly load the result if possible,
4791 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4792 perform an optimized compare on some selected special occasions,
4793 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4794 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4795 generate an IVT any more,
4796 * src/pic16/main.c (pic16_optionsTable): added command line option
4798 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4799 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4801 * src/pic16/NOTES: Raphael Neider added in list of active developers
4802 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4803 jumptable_end to prevent bug #,
4804 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4805 inCond and outCond fields,
4806 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4807 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4808 turn off register spilling,
4809 * (packRegsForOneUse): synced with other ports' versions although it
4810 is not used currently,
4811 * (pic16_packRegisters): added an optimization while reading
4812 structure bitfields, some registers may be saved (malloc code is
4813 decreased by 80 bytes)
4815 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4817 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4818 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4819 this can be optimized more?
4821 2005-03-10 Raphael Neider <rneider AT web.de>
4823 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4824 genNearPointerGet): (hopefully) fixed access to bitfields via
4825 pointers (p->bitN = x; and x = p->bitN; failed)
4827 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
4829 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

4868 2005-02-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4870 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
4871 to keep the correct label reference count when adding/removing references
4872 to labels. A peephole file using this is appended to patch #1144962.

5015 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
5016 this might fix SIGSEGVs on MinGW...

5460 generated for switch statements. For now you need to set the
5461 environment variable SDCC_SJMP_JUMPTABLE to enable this.
5462 Now 4 algorithms for mcs51 jumptable generation are used:
5463 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

5497 * added libc directory. The current version of LibC contains string
5498 functions, ctype functions and macros and some functions of the
5499 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
5500 be extensively tested in the future. Standard disclaimer here.

5513 * (pic16_storeForReturn): optimized return of 0,
5514 * (genCmp): experimental code for new genCmp which uses PIC18's
5515 special compare&skip instructions. Initial tests fail some times
5516 with variables grater than 1 byte in size, so new code is disabled,
5517 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5519 * (genCast): began a fix to optimize the casting of a bit to another
5520 bit, now assigning a bitfield to another bitfield will fail, sorry,

5535 * src/pic16/ralloc.c (allocReg): add preliminary support for
5536 supporting a limited set of temporary registers,
5538 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8543 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
8545 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
8546 loaded with the linker search paths (-L arguments) and the libraries
8547 to be linked with the current source (-l arguments). Changes
8548 currently will affect only the pic16 port.
8549 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8550 include path the port specific paths and port specific libraries,
8551 * gplink command now contains the $3 argument,
8552 * src/pic16/device.h,
8553 * src/pic16/device.c,: structure PIC_device is made public and
8554 renamed to PIC16_device, the same for variable Pics which is renamed

8569 Documenting changes from previous commits.
8570 * configure.in (version 1.56),
8571 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8572 when generating output files to configure the pic16 library,
8573 but now I've commented it out, since gputils aren't installed in the
8574 SF compile farm, so library won't compile
8576 * device/lib/Makefile.in (version 1.56): initially I've added in
8577 target 'all' the prerequestive 'model-pic16' so it compiled the
8578 pic16 library, but now I've commented it out for the same reasons
8580 * added targets 'model-pic16' and 'objects-pic16' to compile the
8582 * added target 'port-specific-objects-pic16' to handle the
8583 generated libraries and copy them into the build/ directory
8584 * added target 'clean-intermediate-pic16' to clean intermediate
8585 files into pic16 directory
8586 * in target 'installdirs' added line to create directory pic16 in
8587 the installation path

8590 added lines to copy all header files to installation path,
8591 * in target 'installdirs' added line create directory for pic16
8592 headers in the installation path

8607 * src/z80/main.c (_parseOptions): fixed the portmode= command line
8608 option so that it actually works. Made it specific to the z80, since
8609 the gbz80 doesn't have these kinds of I/O ports.
8611 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8613 * device/include/z180.h,

8637 via literal number. The symbol is placed in the corresponding
8638 position of the data ram
8639 * (pic16_dump_section): relocatable and absolute uninitialized
8640 data are now emitted in sorted order to reduce section naming,
8641 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
8642 weren't marked as being in the access bank,
8644 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
8646 Added portion of GNU PIC Library under the directory
8647 device/include/pic16 and device/lib/pic16. These files
8648 contain the declarations of SFRs for the PIC18Fxx2 devices.
8649 The directory is initialized via configure from toplevel.
8651 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>

8679 all over. Telling LaTeX to be less strict with word spacing
8680 to better keep the right margin. Changed some notes about
8681 maintainance of the ports in section 3.2.1 - is it OK like this?
8683 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

8723 * src/pic16/peeph.def: all peepholes with movff are commented out,
8724 because there is a problem in the pcode peep optimizer,
8725 * src/pic16/ralloc.c: the register allocator can now reuse local

8835 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8837 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
8838 (default behaviour).
8840 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8842 A python script to validate compiler diagnostic messages. It can be
8843 used to verify that sdcc complains about bad c source code and

8866 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8868 * sdcc.spec: updated
8869 * device/include/Makefile.in: don't install CVS directories

8877 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8879 PIC16 port related changes:
8880 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8881 added variable stackPos,
8883 * gen.c: genCall, assignResultValue: added support for
8884 pushing/retrieving function parameters to/from stack,
8885 genFunction,genEndFunction: setup stack frame for the
8887 genAddrOf: will be changed according to bug 863624
8889 * added files genutils.c and genutils.h which contain gen*
8890 debugged and optimised functions extracted from gen.c
8892 * glue.c: added variable 'externs' which holds extern symbols,
8893 pic16emitRegularMap: is modified to properly handle relocatable
8894 symbols under the new scheme,
8895 pic16createInterruptVect: is modified
8896 pic16printPublics: is modified to emit 'global' assembler directives,
8897 added pic16_printExterns to print extern symbols,
8898 pic16glue: initializes stack/frame pointer in the beginning of
8899 the assembly output. Temporary hack, will be corrected later,
8900 because gplink yet does not support stack and SDCC does not
8901 yet support a type of crt0.o object to create the final binary.
8903 * Removed many lines that contain 8051 legacy code.
8904 * The code is finally placed under a 'code' directive.
8905 * Added port specific options.
8907 * _process_pragma: simplified since now we do not need *special*
8908 include file to define SFR registers. But a separate header
8909 will be needed. This will be developed later.
8910 * _pic16_parseOptions: added, parses port specific options:
8911 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8912 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8913 --preplace-udata-with=
8915 * _pic16_setDefaultOptions: modified to initialize section names,
8916 but hack is temporarly out of order since it needs improvement.
8917 * _pic16_genAssemblerPreamble: configuration words are emitted by
8918 their address instead of their name. This part is incomplete and
8919 supports only the 18Fxx2 devices. Other devices will emit an error
8920 during assembly since they do not contain the same set of config
8922 * _pic16_genIVT: is modified,
8924 * pcode.c: added definitions for some hardware registers that are needed
8926 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8927 All PCI entries are updated. Now LFSR is supported.
8928 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8929 * added pic16_newpCodeOpLit2 to support instructions with
8930 two literal arguments
8931 * pic16_pCode2str: corrected code that emits assembler instructions
8932 with two literal operands and those that have an access bit modifier
8933 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8934 this fixes a bug which caused some labels to be lost, when an
8935 assembler directive was added, i.e. banksel,
8936 * pic16_FixRegisterBanking: improved logic that causes the insertion
8938 * InlineFunction: functions that are called once, are not any more
8939 inlined. This can be a port option in the future,
8941 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8943 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8944 hold the corresponding uninitialized symbols,
8945 * pic16_allocProcessorRegister: registers have explicit marked the
8947 * pic16_allocInternalRegister: registers are explicit marked as
8949 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8950 processing list, so bit registers were lost,
8953 * ralloc.h: added field 'accessBank' and original symbol operand
8954 in register definition,
8955 * removed the field isMapped from register definition,
8957 ** Several functions have been removed from various sources:
8958 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8959 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8960 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8961 pic16_assignRelocatableRegisters
8963 ** others have been introduced:
8964 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8965 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8967 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8969 * support/scripts/inc2h.pl: changed definition of BIT_AT
8970 to emit 'sbit at' instead of 'bit at'. This was a request.
8972 PIC16 port related preliminary changes:
8973 * gen.c: prefixed function popRegFromString with
8974 pic16_ and all references to it corrected
8975 * pcode.c: all pic16_pc_* hardware registers prefixed
8976 with underscore (_),
8977 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8978 * ralloc.c: newReg(): when register is REG_SFR then
8979 set address to rIdx,
8980 pic16_allocProcessorRegister(): marks register wasUsed=0
8981 pic16_writeUsedRegs(): added a call to assign processor
8982 registers via pic16_assignFixedRegisters
8984 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8986 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8987 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8988 variables in unused register banks. Also the SSEG is placed
8989 wherever there is enough space for it, and IDATA can be anywhere
8990 in internal RAM. For now compile using -Wl-Y[stack_size].
8991 The mem file is different for this option as well, since it
8992 makes no sense of talking about DSEG lenght.
8994 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8996 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8997 in certain cases, e.g. when ROM assignment, patch provided
8998 from Albert den Haan.
9000 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

9143 * src/mcs51/peephole.def,
9144 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
9145 (allows non-interrupt and interrupt code to safely compete for a resource

9828 genCodePointerGet, genGenPointerGet, genFarPointerSet,
9829 genGenPointerSet): handle AOP_DPTR correctly when loading dptr

9906 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9908 Fixed bug #621531 (const & volatile confusion in the type chain).
9909 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
9910 refer to the const or volatile state of the pointer itself.

9980 2003-09-04 Bernhard Held <bernhard AT bernhardheld.de>
9982 * device/lib/_mullong.c: replaced int by short for gcc
9984 2003-08-31 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9987 and JUMPTABLE iCodes properly now (worked by accident before)
9988 * src/mcs51/gen.c (leftRightUseAcc),
9989 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
9990 iCode properly now. Use getSize instead of nRegs since a & b
9991 aren't part of the nRegs tally.
9993 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
9995 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

9997 before instructions that use the _STATUS register
9999 2003-08-31 Bernhard Held <bernhard AT bernhardheld.de>
10001 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
10002 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
10003 fetching of the pointer
10004 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
10005 copied from genNearPointerSet()
10006 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
10007 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
10008 If they pop r0/r1 they must be called in the opposite order than aopOp().
10009 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
10010 (resp. --stack-auto), prepared for --xstack
10012 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

10021 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
10023 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10024 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
10025 type for bits was changed. It resulted in bit variables becoming
10026 global, which is not permitted in PIC 14 assembly output.
10028 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10030 * doc/sdccman.lyx: various additions and updates. Rearranged sections
10032 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10034 Z80 and MCS51 linkers complaint if a public symbol is defined

10041 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10043 A few small changes that speed up the peephole optimizer.
10047 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10049 Try to make the peephole optimizer smarter by maintaining
10050 an association between the assembly source code and the
10051 iCodes that originated them. Put this information to use
10052 with a new peephole rule condition "notVolatile" so that
10053 the rules can be aggressive yet still safe.
10058 * src/mcs51/peeph.def
10060 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10064 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
10065 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
10066 if the left or right operand symbols have the accuse flag set.
10068 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10070 Changed the type of the result of the ! (NOT) operator to char;
10071 previously it returned the same type as the source. This allows
10072 us to eliminate all the genFloatNot functions (all of its target
10073 implementations were very buggy) since !float can use the same
10076 * src/SDCCicode.c (ast2iCode): ! returns char
10077 * src/mcs51/gen.c (genNot, genNotFloat),
10078 * src/ds390/gen.c (genNot, genNotFloat),
10079 * src/z80/gen.c (genNot, genNotFloat),
10080 * src/pic/gen.c (genNot, genNotFloat),

10085 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10086 1. Interrupt would not compile properly. Ensure PCLATH register is saved
10087 during interrupts. Ensure WSAVE is located at a shared bank address.
10088 2. Fixed page selection in some places
10089 3. Fixed BTFSS/C to where necessary use registers directly and not simply
10090 the registers name strings.
10091 4. Fixed "signed / unsigned compare" compiler warnings.
10092 5. The PIC port manages its own allocation of the general purpose
10093 registers, but makes no attempt to reuse them. As a result when
10094 compiling it soon runs out of general purpose registers. Some
10095 additional code was added to the files pcode.c and device.c to walk
10096 through the function call tree and rename the registers so that they
10106 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
10107 genPlus() & genMinus() when the result is the same as left or right
10109 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

10113 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10115 Made bitfield a distinct type from bit so that bitfields
10116 convert as per ANSI C and bits retain their traditional
10117 boolean style behaviour. Implemented bitfield support in
10125 * src/ds390/gen.c: bit v bitfield split
10126 * src/z80/gen.c: New support for bitfields
10127 * support/regression/tests/bitfields.c: reenabled z80,
10130 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10132 Rules 246.x, 247.x relate to bitfields, the others speed up
10133 access to xdata mapped I/O devices.
10135 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
10137 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10139 Cleaned up genPackBits and genUnpackBits and added two helper
10140 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
10141 for literal assignments in genPackBits (thanks to Frieder for
10147 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10149 Fixed bug #748310 (pointer to function type mishandled when the
10150 function name is omitted). Also fixed a SIGSEGV when a function
10151 attribute (reentrant, etc) is used on a non-function or on a
10152 function but misplaced before the parameter list.
10154 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
10156 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
10157 * support/Util/SDCCerr.h,
10158 * support/Util/SDCCerr.c: Added func attr misuse error msg
10160 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
10162 Fixed bug #787649 by anonymous
10163 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
10164 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
10166 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

10179 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10181 Made the constant following the "interrupt" keyword optional. If
10182 omitted, the function will not automatically be given an entry
10183 in the interrupt vector table (similar to #pragma NOIV, but
10184 less syntacticly kludgy). The interrupt number is also now
10185 range checked. Also fixed a bug in the high order bit example
10192 * support/Util/SDCCerr.c
10193 * support/Util/SDCCerr.h
10196 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
10198 * src/SDCCcse.c (algebraicOpts): fix bug converting op from value to type

10718 the compiler with no port specified on command line, a default
10719 port is selected with the new macro DEFAULT_PORT which is
10720 defined in port.h, in setDefaultOptions() linkOptions is removed

10724 which returns the i'th item of a set variable. See SDCCset.c, in
10725 linkEdit() when calling buildCmdLine(), added linkOptions as
10726 last argument. Now users can pass arguments to gplink via the
10727 -Wl option, main() uses pic16glue() to glue up pic16 programs

10742 _asmCmd changed to be more gplink and gpasm friendly
10743 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10744 produced an error when parsed, peep rule 12 is added to utilize
10745 movff, but it is commented out since the pCode does not support
10746 yet a command with 2 address arguments

11808 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
11809 * src/mcs51/main.c: removed {bindir}{sep} from aslink
11811 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11813 * in /sdcc/as/mcs51/ changed these files in order to create an
11814 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11815 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11816 following files to include the previous two files: aslink.dsp,
11817 Makefile.aslink, Makefile.bcc, and Makefile.in.
11819 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11820 .adb instead of .cdb
11822 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11824 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11825 value from option --iram-size.
11827 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11829 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11832 2002-09-18 <wiml AT hhhh.org>
11834 * SDCClrange.h: exposed setFromRange() and setToRange()
11835 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11836 packRegsForAccUse() (bug 542397)
11837 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11838 multiple times and emitting the fetch operations more than once
11839 added aopGetUsesAcc() function to allow binary operators to
11840 fetch their operands in the correct order; made genMinus() emit
11841 compact code for X = LITERAL - Y
11843 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11844 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11845 sprintf() in line 1267.
11847 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11848 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11851 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11852 Changes to aslink (All the changes are marked with 'JCF'):
11854 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11857 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11858 area BSEG. Also moves, if possible, the DATA area down into the internal
11859 ram so more space is available.
11861 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11864 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11865 not bytes. Function summary() which creates a memory usage summary
11866 file with extension .mem. Reports of overlaping stack and small stack
11867 size. If the space for the stack is less than 16 bytes aslink trows a
11870 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11871 the 8051. Option 'y' for memory summary output file.
11873 Changes to sdcc (All the changes are marked with 'JCF'):
11875 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11877 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11878 overlaying area for it (uses RegBankUsed[4]).
11880 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11881 bank zero as used by default. By default aslink locates the stack
11882 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11883 the creation of the .mem file. Delegates the allocation of data area
11884 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11885 the begining of the stack area to aslink.
11887 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11888 glue() in SDCCglue.c creates an area for it.
11890 2002-09-03 Borut Razem <borut.razem AT siol.net>
11891 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11892 sdcc/src/pic/glue.c:
11893 introduced atexit() handler for teporay files removal in case of
11894 errors, assertions, ...
11896 2002-08-29 Borut Razem <borut.razem AT siol.net>
11897 * sdcc/support/cpp2/auto-host_vc_in.h:
11898 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11899 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11900 Maybe there is a similar problem with BORLANDC? It should be checked!
11902 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11903 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11904 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11905 was not executed, and the compiler (cl) launched a warning:
11906 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11908 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11909 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11911 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11912 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11914 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11915 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,

11917 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11918 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11919 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11920 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11921 - added Release configuration in VS projects
11922 - review of compiler an linker options
11923 - VC .exe files are generated in bin_vc directory, not to interfere
11924 with binaries generated from other projects (cygwin, mingw, bcc ...)
11926 * sdcc/src/yacc.dsp: added
11928 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11929 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11930 and insert the version number definitions from .version
11932 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11934 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11935 added - genarate auto-host.h using auto-host_vc_in.h as template
11938 removed from CVS, generated automatically
11940 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11941 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11943 2002-08-11 Borut Razem <borut.razem AT siol.net>
11944 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11946 2002-08-10 Borut Razem <borut.razem AT siol.net>
11947 * src/SDCCmain.c (main):
11948 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11949 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11950 The consequence was that some temporary files were not removed.
11953 unification of code in functions tempfilename() and tempfile():
11954 function tempnam() is defined in Visual Studio 6.0 and .NET
11956 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11958 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11959 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11960 - removed compiler command line option /WX: Treats all warnings as errors
11961 - update a list of source files, included into the project
11963 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11964 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11965 changed project type to Generic Project so that can be correcly converted to VS.NET project
11967 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11969 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11971 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11973 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:

11980 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11981 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11982 - solved MSC error in function aopDump()

12162 Previous fix was not good. basic blocks that have "break" or "return" are
12163 not really partof a loop , but live ranges used in these blocks should
