1604 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1606 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1607 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1609 One basic decision: e.g. src/clean.mk includes further files. In order
1610 to make this work there are two solutions:
1611 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1612 run configure on them. This way they can use
1613 'include $(srcdir)/port-clean.mk'
1614 - always include clean.mk by the Makefile at the same level. To avoid
1615 that `make clean` tries to include and build Makefile.dep the
1616 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1617 implemented, because now even `make uninstall` doesn't create
1618 Makefile.in. clean.mk could be eliminated by pasting it in
1621 * debugger/mcs51/Makefile.in: build own objects from library sources
1622 (SLIB, SDCC) in current directory
1624 * configure, configure.in: renamed --disable-device-lib-build in
1625 --disable-device-lib; added --enable-doc, the required tools are
1626 searched by configure; added result message; the toolchain for the
1627 belonging ports are now only built, if the port is enabled.
1629 * support/regression/*: all output is written in directory gen, because
1630 the fwk and ports directories don't livet in the build tree using vpath
1632 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1633 --disable-device-lib, added --enable-doc, added section VPATH
1635 * sim/ucsim/configure.in,
1636 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1637 z80 are enabled by default
1639 2006-04-24 Raphael Neider <rneider AT web.de>
1641 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1642 to config word, "pic14_"-prefixed some extern functions
1643 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1644 config word has been found
1645 * src/pic/device.h: added prototypes
1646 * src/pic/pcode.c: added "pic14_"-prefix where needed
1647 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
1649 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

1652 (pic14createInterruptVect): moved generating __config directives away

1663 fixes #1469504 and #1474602,
1664 (pCodeRegOptimizeRegUsage): fixed typo in comment

1912 and enabled nesting of critical functions though not for gbz80
1913 (genCritical, genEndCritical): added functions
1914 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1915 * src/z80/mappings.i: added "ei" to all mappings

1932 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1934 * src/.version: increased version number to 2.5.5
1935 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1936 linking is done manually in pic16 port's _linkEdit,
1937 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1938 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1939 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1940 allocate asmop as AOP_ACC,
1941 (aopForRemat): added parameter 'bool result' in function declaration,
1942 (pic16_aopGet): return AOP_ACC when accessing WREG,
1943 (pic16_popGetTempReg): minor modification,

1954 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1955 call to allocReg, not by manually allocating a new one,
1956 (pic16_assignRegisters): now before going through the register
1957 allocating functions mark all registers as free. This eliminates some
1958 side effects resulting from peephole parser done earlier in the backbone
1960 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

2021 'xinst' for initial support for Extended Instruction Support,
2022 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
2023 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
2024 port->fun_prefix anymore (may change later),
2025 (genFunction, genEndFunction): do not store/restore local registers for
2026 _main (this should take care the --main-return command line option in
2028 (genOr): removed some legacy pic-port instructions,
2029 * src/pic16/genarith.c (genAddLit): re-enabled old code because
2030 performing operations with SFR's causes data to be written more than
2031 once to each SFR. Perhaps SFRs should be handled in special cases...
2032 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
2034 * src/pic16/main.c (_process_pragma): stack bound checking did not take

2039 (deassignLRs): *** perhaps the most important change, old 'for' code
2040 (commented out for reference), didn't account for some registers which
2041 were left marked 'not free' after a pointer operation. The change
2042 reduces register usage a lot in some cases

4315 * src/SDCCglobal.h (struct options),
4317 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
4318 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
4319 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
4320 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
4321 always available in leading double underscore form. The C99 support is
4322 mostly missing, but it's a start.
4323 * support/regression/tests/bug-227710.c: fixed nonconforming use of
4324 reserved identifier "__data".
4326 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

4370 immedDom() returning wrong block; probably fixes bug #1160833)
4372 2005-03-20 Borut Razem <borut.razem AT siol.net>
4374 * support/scripts/inc2h.pl: WIN32 port
4376 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
4378 * device/lib/makefile.in: added abs.c and labs.c
4380 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
4382 * device/include/stdint.h: added
4383 * device/lib/abs.c: added
4384 * device/lib/labs.c: added
4385 * device/include/stdlib.h: added abs() and labs() prototypes

4400 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
4402 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
4404 * device/lib/printf_large.c: removed inline assembly for portability and
4405 readability. Use printf_fast if speed or size are more important.
4406 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4407 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4409 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4411 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4412 prevent compiler warning
4414 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4416 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4417 moved to level 0 and declared as static. Also they are explicit
4418 placed in access bank. This was necessery because some times they
4419 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4420 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4421 optimizations. Currently only compare to unsigned char is implemented,
4422 * src/pic16/gen.c: added fReturnIdx array,
4423 * (struct resolvedIfx) is moved to gen.h and made public,
4424 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4425 * (aopForSym): added an optimization to directly store in stack of
4426 the operand of a SEND iCode,
4427 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4428 but as registers instead (AOP_REG) using the fReturnIdx array,
4429 * (pic16_freeAsmop): remove the freed register from the
4430 _G.sregsAlloc field,
4431 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4432 a compare of 'WREG',
4433 * (pic16_popGetTempRegCond): changed function prototype, now
4434 function takes also a bitVector argument v which holds the current
4435 set of registers that are allocated for stack access by aopForSym,
4436 registers allocated in aopForSym for accessing stack symbols are not
4437 any more part of the functions usedRegs field,
4438 * (genCall): some times aopOp is called for a stack variable to be
4439 send, aopForSym might perform the push, if this is true make sure
4440 that genCall doesn't push the variable twice by testing _G.resDirect,
4441 * (genFunction): changed testing for unspecified interrupt number
4442 from 256 to INTNO_UNSPEC,
4443 * modified selection scheme of frame pointer generation. Previously
4444 if function did use local registers a frame pointer was generated,
4445 now a frame pointer is generated only if function has arguments
4446 (that need PLUSW2 register access), or has stack arguments, or the
4447 compiler is not instructed to omit the frame pointer,
4448 * (genEndFunction): before restoring local registers that were saved
4449 in the function preamble, also restore the registers that *might*
4450 have been allocated for stack access,
4451 * (genRet): removed some old comments,
4452 * (genCmp, the active (RN's) version): added a call to the
4453 pic16_genCmp_special function to perform the compare with a more
4454 robust and optimized way,
4455 * (genInline): a feature has been added in inline code generation,
4456 which allows a wildcard variable substitution when writing inline
4457 assembly. Code is incomplete and experimental therefore undocumented,
4458 * (genCast): changed order of aopOp for result and right to allow
4459 aopForSym to directly load the result if possible,
4460 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4461 perform an optimized compare on some selected special occasions,
4462 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4463 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4464 generate an IVT any more,
4465 * src/pic16/main.c (pic16_optionsTable): added command line option
4467 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4468 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4470 * src/pic16/NOTES: Raphael Neider added in list of active developers
4471 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4472 jumptable_end to prevent bug #,
4473 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4474 inCond and outCond fields,
4475 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4476 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4477 turn off register spilling,
4478 * (packRegsForOneUse): synced with other ports' versions although it
4479 is not used currently,
4480 * (pic16_packRegisters): added an optimization while reading
4481 structure bitfields, some registers may be saved (malloc code is
4482 decreased by 80 bytes)
4484 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4486 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4487 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4488 this can be optimized more?
4490 2005-03-10 Raphael Neider <rneider AT web.de>
4492 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4493 genNearPointerGet): (hopefully) fixed access to bitfields via
4494 pointers (p->bitN = x; and x = p->bitN; failed)
4496 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

4684 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
4685 this might fix SIGSEGVs on MinGW...
4686 * src/SDCCopt.c (killDeadCode): restored original behaviour
4687 (volatile operands might get thrown away though)
4689 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

4768 * src/SDCCglobl.h: ensure that PATH_MAX >= 2048 to guarantee
4769 cmdLine buffers (used when calling sdcpp...) are large enough
4770 (MAX_PATH=256 truncates arguments leading to system halts when
4772 * src/pic16/gen.c (pic16_sameRegs): relaxed size criterion
4773 * (genUminus): rewritten to for efficiency
4774 * (genNearPointer[GS]et): enforce reloading of FSR0 (was still
4775 used uninitialized in some cases)
4776 * (genCast): upcasting a 16bit int to a 24bit GPOINTER may not
4777 copy the third byte from the int -- now assumes 0x80 (data memory)
4778 * src/pic16/genarith.c (pic16_genPlus): fixed bug when swapping
4779 operands (genAddLit expects the iCode's operands to swapped as
4780 well), fixed leftover bytes (crashed for short left operands)
4781 * (pic16_genMinusDec): performance improvements, removed false
4783 * (pic16_genMinus): fixed to cope with differently sized operands
4784 * src/pic16/glue.c (pic16_glue): added new banksel optimization
4786 * src/pic16/pcode.c: implemented (first phase of) banksel optimization
4787 * src/pic16/graph.[ch]: implementation of directed graphs, used by
4788 new banksel optimization

4811 * src/pic16/ralloc.c (decodeOp): removed static declaration and
4812 renamed to pic16_decodeOp,

4814 sequences that test a single bit for 1/0
4816 2005-01-12 Vangelis Rokas <vrokas AT otenet.gr>
4818 * src/pic16/pcode.[ch]: introduced pic16_stackpnt_*,
4819 pic16_framepnt_*, pic16_stack_*, pic1_frame_* pointer variables to
4820 access stack and frame pointers. They are initially assigned to
4821 point at pic16_pc_fsr1[lh] and pic16_pc_fsr2[lh] variables and other
4822 accessing SFRs. Updated all occurences of modification of stack or
4823 frame pointer in gen.c and pcode.c,
4824 * src/pic16/ralloc.c (serialRegAssign): fixed two bugs with
4825 assigning of a literal value to pointers,
4826 * src/pic16/main.c (pic16_finiliseOptions): set pre-processor define
4827 flag STACK_MODEL_SMALL or STACK_MODEL_LARGE according to the model

4851 * src/pic16/gen.c (genIfxJump): fixed inverted skips on CARRY
4852 * (genIfx): fixed (?) read from uninitialized SPIL_LOC (now assumes CARRY
4853 to hold the condition bit)
4854 * added new version of genCmp (old code available via #define)
4855 * added new version of genShiftLeft/genShiftRight in a generic
4856 way, now supports shifting by negative values

4868 from Raphael Neider,
4869 * src/pic16/pcode.c (pic16_newpCodeOpLit): removed casting to char
4870 for 8-bit literals. This fixes some literal operands which are sign
4871 extended to 16-bits ints when instruction needs only 8-bits.

5128 Adding support for replacing ljmps with sjmps in jumptables
5129 generated for switch statements. For now you need to set the
5130 environment variable SDCC_SJMP_JUMPTABLE to enable this.
5131 Now 4 algorithms for mcs51 jumptable generation are used:
5132 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
5133 addresses loaded pc-relative for up to 112 cases and stack-pushing
5134 target addresses loaded with offset from dptr for up to 256 cases.
5136 * src/SDCCpeeph.c: added peephole conditional labelJTInRange

5160 Large cummulative patch for pic16 port.
5161 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
5162 to call when a stack overflow occurs,
5163 * (malloc.h): added CVS Id tag,
5164 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
5166 * added libc directory. The current version of LibC contains string
5167 functions, ctype functions and macros and some functions of the
5168 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
5169 be extensively tested in the future. Standard disclaimer here.
5170 Library is not automatically build yet. But one can build it by
5171 invoking 'make' inside the libc directory.
5172 * added ADC library under libio. Preliminary version yet.
5174 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
5175 * src/pic16/gen.c (aopForRemat): asmop size is filled by
5176 aopForRemat() now and not by pic16_aopOp(),
5177 * (pic16_popGetTempReg): removed warning messgae when allocating
5178 temporary registers, its a buggy feature and will be removed,
5179 * (pic16_popGet): set register instance field in AOP_CRY,
5180 * (pic16_outBitC): fixed for results in size greater than 1,
5181 * (genUminusFloat): fixed for pic16, ported code from mcs51,
5182 * (pic16_storeForReturn): optimized return of 0,
5183 * (genCmp): experimental code for new genCmp which uses PIC18's
5184 special compare&skip instructions. Initial tests fail some times
5185 with variables grater than 1 byte in size, so new code is disabled,
5186 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5188 * (genCast): began a fix to optimize the casting of a bit to another
5189 bit, now assigning a bitfield to another bitfield will fail, sorry,

7839 * src/SDCCicode.c (usualBinaryConversions): removed pic16 from ports
7840 which can't handle SDCC_NEWONEBYTEOPS,
7841 (geniCodeMultiply): removed conversion from mult to shift for pic14
7844 2004-02-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7864 * src/SDCCicode.c: Mult/Div/ModOneByte ops can handle all kind of signed
7865 arguments with 8 or 16 bit results; pic14 and pic16 ports use old
7866 promotion behaviour; env. var. SDCC_NEWONEBYTEOPS selects the new,
7867 SDCC_OLDONEBYTEOPS selects the old behaviour

8212 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
8214 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
8215 loaded with the linker search paths (-L arguments) and the libraries
8216 to be linked with the current source (-l arguments). Changes
8217 currently will affect only the pic16 port.
8218 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8219 include path the port specific paths and port specific libraries,
8220 * gplink command now contains the $3 argument,
8221 * src/pic16/device.h,
8222 * src/pic16/device.c,: structure PIC_device is made public and
8223 renamed to PIC16_device, the same for variable Pics which is renamed

8238 Documenting changes from previous commits.
8239 * configure.in (version 1.56),
8240 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8241 when generating output files to configure the pic16 library,
8242 but now I've commented it out, since gputils aren't installed in the
8243 SF compile farm, so library won't compile
8245 * device/lib/Makefile.in (version 1.56): initially I've added in
8246 target 'all' the prerequestive 'model-pic16' so it compiled the
8247 pic16 library, but now I've commented it out for the same reasons
8249 * added targets 'model-pic16' and 'objects-pic16' to compile the
8251 * added target 'port-specific-objects-pic16' to handle the
8252 generated libraries and copy them into the build/ directory
8253 * added target 'clean-intermediate-pic16' to clean intermediate
8254 files into pic16 directory
8255 * in target 'installdirs' added line to create directory pic16 in
8256 the installation path
8258 * device/include/Makefile.in (version 1.11): in target 'install'
8259 added lines to copy all header files to installation path,
8260 * in target 'installdirs' added line create directory for pic16
8261 headers in the installation path

8277 option so that it actually works. Made it specific to the z80, since
8278 the gbz80 doesn't have these kinds of I/O ports.
8280 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8306 via literal number. The symbol is placed in the corresponding
8307 position of the data ram
8308 * (pic16_dump_section): relocatable and absolute uninitialized
8309 data are now emitted in sorted order to reduce section naming,
8310 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
8311 weren't marked as being in the access bank,
8313 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
8315 Added portion of GNU PIC Library under the directory
8316 device/include/pic16 and device/lib/pic16. These files
8317 contain the declarations of SFRs for the PIC18Fxx2 devices.
8318 The directory is initialized via configure from toplevel.
8320 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>

8347 * doc/sdccman.lyx: Moved and added some sections, small changes
8348 all over. Telling LaTeX to be less strict with word spacing
8349 to better keep the right margin. Changed some notes about
8350 maintainance of the ports in section 3.2.1 - is it OK like this?
8352 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

8390 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
8392 * src/pic16/peeph.def: all peepholes with movff are commented out,
8393 because there is a problem in the pcode peep optimizer,
8394 * src/pic16/ralloc.c: the register allocator can now reuse local
8395 function symbols for another function. This saves register usage.
8396 * src/pic16/ralloc.h: added flag isLocal in structure regs,
8398 Added file src/pic16/NOTES with information about program writing on
8399 the current port version.

8466 arguments via -W option
8467 * src/pic16/main.c: added $l in _asmCmd, changed extension for
8468 object file from '.rel' to '.o' in port->linker structure,

8471 2004-01-07 Borut Razem <borut.razem AT siol.net>
8473 * support/scripts/sdcc.nsi: update PATH
8474 * support/scripts/sdcc.ico: craeted

8487 include information about variables allocated to the overlay
8490 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8492 * as/mcs51/lkmain.c: Help about -Y option

8504 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8506 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
8507 (default behaviour).
8509 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8511 A python script to validate compiler diagnostic messages. It can be
8512 used to verify that sdcc complains about bad c source code and
8513 gives a good location of the error.
8514 * support/valdiag/Makefile,
8515 * support/valdiag/valdiag.py,
8516 * support/valdiag/tests/*

8533 Bug reported from Jesus Calvino-Fraga
8535 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8537 * sdcc.spec: updated
8538 * device/include/Makefile.in: don't install CVS directories
8539 * device/lib/Makefile.in: added removal of CVS directories after install
8540 * doc/Makefile: fixed install, added local_icons
8541 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8542 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8543 * src/ds390/gen.c (genRightShift): fixed bug #870788
8544 * src/SDCCast.c (decorateType): fixed bug #870781
8546 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8548 PIC16 port related changes:
8549 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8550 added variable stackPos,
8552 * gen.c: genCall, assignResultValue: added support for
8553 pushing/retrieving function parameters to/from stack,
8554 genFunction,genEndFunction: setup stack frame for the
8556 genAddrOf: will be changed according to bug 863624
8558 * added files genutils.c and genutils.h which contain gen*
8559 debugged and optimised functions extracted from gen.c
8561 * glue.c: added variable 'externs' which holds extern symbols,
8562 pic16emitRegularMap: is modified to properly handle relocatable
8563 symbols under the new scheme,
8564 pic16createInterruptVect: is modified
8565 pic16printPublics: is modified to emit 'global' assembler directives,
8566 added pic16_printExterns to print extern symbols,
8567 pic16glue: initializes stack/frame pointer in the beginning of
8568 the assembly output. Temporary hack, will be corrected later,
8569 because gplink yet does not support stack and SDCC does not
8570 yet support a type of crt0.o object to create the final binary.
8572 * Removed many lines that contain 8051 legacy code.
8573 * The code is finally placed under a 'code' directive.
8574 * Added port specific options.
8576 * _process_pragma: simplified since now we do not need *special*
8577 include file to define SFR registers. But a separate header
8578 will be needed. This will be developed later.
8579 * _pic16_parseOptions: added, parses port specific options:
8580 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8581 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8582 --preplace-udata-with=
8584 * _pic16_setDefaultOptions: modified to initialize section names,
8585 but hack is temporarly out of order since it needs improvement.
8586 * _pic16_genAssemblerPreamble: configuration words are emitted by
8587 their address instead of their name. This part is incomplete and
8588 supports only the 18Fxx2 devices. Other devices will emit an error
8589 during assembly since they do not contain the same set of config
8591 * _pic16_genIVT: is modified,
8593 * pcode.c: added definitions for some hardware registers that are needed
8595 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8596 All PCI entries are updated. Now LFSR is supported.
8597 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8598 * added pic16_newpCodeOpLit2 to support instructions with
8599 two literal arguments
8600 * pic16_pCode2str: corrected code that emits assembler instructions
8601 with two literal operands and those that have an access bit modifier
8602 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8603 this fixes a bug which caused some labels to be lost, when an
8604 assembler directive was added, i.e. banksel,
8605 * pic16_FixRegisterBanking: improved logic that causes the insertion
8607 * InlineFunction: functions that are called once, are not any more
8608 inlined. This can be a port option in the future,
8610 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8612 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8613 hold the corresponding uninitialized symbols,
8614 * pic16_allocProcessorRegister: registers have explicit marked the
8616 * pic16_allocInternalRegister: registers are explicit marked as
8618 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8619 processing list, so bit registers were lost,
8622 * ralloc.h: added field 'accessBank' and original symbol operand
8623 in register definition,
8624 * removed the field isMapped from register definition,
8626 ** Several functions have been removed from various sources:
8627 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8628 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8629 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8630 pic16_assignRelocatableRegisters
8632 ** others have been introduced:
8633 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8634 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8636 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8638 * support/scripts/inc2h.pl: changed definition of BIT_AT
8639 to emit 'sbit at' instead of 'bit at'. This was a request.
8641 PIC16 port related preliminary changes:
8642 * gen.c: prefixed function popRegFromString with
8643 pic16_ and all references to it corrected
8644 * pcode.c: all pic16_pc_* hardware registers prefixed
8645 with underscore (_),
8646 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8647 * ralloc.c: newReg(): when register is REG_SFR then
8648 set address to rIdx,
8649 pic16_allocProcessorRegister(): marks register wasUsed=0
8650 pic16_writeUsedRegs(): added a call to assign processor
8651 registers via pic16_assignFixedRegisters
8653 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8655 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8656 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8657 variables in unused register banks. Also the SSEG is placed
8658 wherever there is enough space for it, and IDATA can be anywhere
8659 in internal RAM. For now compile using -Wl-Y[stack_size].
8660 The mem file is different for this option as well, since it
8661 makes no sense of talking about DSEG lenght.
8663 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8665 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8666 in certain cases, e.g. when ROM assignment, patch provided
8667 from Albert den Haan.
8669 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8811 SDCC_NOGENRAMCLEAR to disable this.
8812 * src/mcs51/peephole.def,
8813 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
8814 (allows non-interrupt and interrupt code to safely compete for a resource
8815 without the non-interrupt code having to disable interrupts)
8817 2003-12-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8819 * src/SDCCicode.c (geniCodeAdd),

8839 2003-12-11 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8841 * src/z80/ralloc.c: set DISABLE_PACK_HL = 1 as a temporary fix to bug #855165
8843 2003-12-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8912 it breaks with bitfields, extern declarations, and gcse analysis.
8913 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
8914 could be assigned through a pointer, so don't complain.

9692 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9693 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9694 type for bits was changed. It resulted in bit variables becoming
9695 global, which is not permitted in PIC 14 assembly output.

9712 A few small changes that speed up the peephole optimizer.
9716 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9718 Try to make the peephole optimizer smarter by maintaining
9719 an association between the assembly source code and the
9720 iCodes that originated them. Put this information to use
9721 with a new peephole rule condition "notVolatile" so that
9722 the rules can be aggressive yet still safe.
9727 * src/mcs51/peeph.def
9729 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9733 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9734 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9735 if the left or right operand symbols have the accuse flag set.
9737 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9739 Changed the type of the result of the ! (NOT) operator to char;
9740 previously it returned the same type as the source. This allows
9741 us to eliminate all the genFloatNot functions (all of its target
9742 implementations were very buggy) since !float can use the same
9745 * src/SDCCicode.c (ast2iCode): ! returns char

9754 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9755 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9756 during interrupts. Ensure WSAVE is located at a shared bank address.
9757 2. Fixed page selection in some places
9758 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9759 the registers name strings.
9760 4. Fixed "signed / unsigned compare" compiler warnings.
9761 5. The PIC port manages its own allocation of the general purpose
9762 registers, but makes no attempt to reuse them. As a result when
9763 compiling it soon runs out of general purpose registers. Some
9764 additional code was added to the files pcode.c and device.c to walk
9765 through the function call tree and rename the registers so that they
9775 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9776 genPlus() & genMinus() when the result is the same as left or right

9782 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9784 Made bitfield a distinct type from bit so that bitfields
9785 convert as per ANSI C and bits retain their traditional
9786 boolean style behaviour. Implemented bitfield support in
9794 * src/ds390/gen.c: bit v bitfield split
9795 * src/z80/gen.c: New support for bitfields
9796 * support/regression/tests/bitfields.c: reenabled z80,
9799 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9801 Rules 246.x, 247.x relate to bitfields, the others speed up
9802 access to xdata mapped I/O devices.

9809 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9810 for literal assignments in genPackBits (thanks to Frieder for
9816 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9818 Fixed bug #748310 (pointer to function type mishandled when the
9819 function name is omitted). Also fixed a SIGSEGV when a function
9820 attribute (reentrant, etc) is used on a non-function or on a
9821 function but misplaced before the parameter list.
9823 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9825 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

9850 Made the constant following the "interrupt" keyword optional. If
9851 omitted, the function will not automatically be given an entry
9852 in the interrupt vector table (similar to #pragma NOIV, but
9853 less syntacticly kludgy). The interrupt number is also now
9854 range checked. Also fixed a bug in the high order bit example

9875 unsigned, but are signed by default
9876 * src/SDCCval.c (constVal): rearranged
9877 * src/SDCCval.c (valMod): preliminary fix
9878 * src/SDCCval.c (valCastLiteral): use TYPE_* types

10374 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
10375 it can be defined with CFLAGS when running configure
10376 * src/SDCCmain.c: fixed compiling + linking with object files
10378 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

10383 * src/SDCCmain.c: linkOptions is changed to set *,
10384 added if/endif conditional macros to remove options help
10385 messages from optionsTable when a port is not configured, added
10386 support for the PIc16 port in the ports table, when executing
10387 the compiler with no port specified on command line, a default
10388 port is selected with the new macro DEFAULT_PORT which is
10389 defined in port.h, in setDefaultOptions() linkOptions is removed
10390 from initialization assignment, since now it is a set,
10391 parseCmdLine uses setParseWithComma for linkOptions, in
10392 linkEdit() linkOptions are accessed with new function indexSet()
10393 which returns the i'th item of a set variable. See SDCCset.c, in
10394 linkEdit() when calling buildCmdLine(), added linkOptions as
10395 last argument. Now users can pass arguments to gplink via the
10396 -Wl option, main() uses pic16glue() to glue up pic16 programs
10397 * src/SDCCpeeph.c: various changes to support pic16
10398 * src/SDCCset.c: added function void *indexSet(set *, int) to

10408 * src/pic16/glue.c: commented out some error producing lines
10409 * src/pic16/main.c: __config directives are commented out to stop
10410 gpasm complaining and test the linkage with gplink, _linkCmd and
10411 _asmCmd changed to be more gplink and gpasm friendly
10412 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10413 produced an error when parsed, peep rule 12 is added to utilize
10414 movff, but it is commented out since the pCode does not support
10415 yet a command with 2 address arguments
10417 2003-05-18 <johan AT balder>
10419 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

11480 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11482 * in /sdcc/as/mcs51/ changed these files in order to create an
11483 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11484 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11485 following files to include the previous two files: aslink.dsp,
11486 Makefile.aslink, Makefile.bcc, and Makefile.in.
11488 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11489 .adb instead of .cdb
11491 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11493 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11494 value from option --iram-size.
11496 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11498 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11501 2002-09-18 <wiml AT hhhh.org>
11503 * SDCClrange.h: exposed setFromRange() and setToRange()
11504 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11505 packRegsForAccUse() (bug 542397)
11506 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11507 multiple times and emitting the fetch operations more than once
11508 added aopGetUsesAcc() function to allow binary operators to
11509 fetch their operands in the correct order; made genMinus() emit
11510 compact code for X = LITERAL - Y
11512 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11513 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11514 sprintf() in line 1267.
11516 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11517 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11520 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11521 Changes to aslink (All the changes are marked with 'JCF'):
11523 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11526 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11527 area BSEG. Also moves, if possible, the DATA area down into the internal
11528 ram so more space is available.
11530 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11533 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11534 not bytes. Function summary() which creates a memory usage summary
11535 file with extension .mem. Reports of overlaping stack and small stack
11536 size. If the space for the stack is less than 16 bytes aslink trows a
11539 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11540 the 8051. Option 'y' for memory summary output file.
11542 Changes to sdcc (All the changes are marked with 'JCF'):
11544 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11546 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11547 overlaying area for it (uses RegBankUsed[4]).
11549 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11550 bank zero as used by default. By default aslink locates the stack
11551 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11552 the creation of the .mem file. Delegates the allocation of data area
11553 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11554 the begining of the stack area to aslink.
11556 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11557 glue() in SDCCglue.c creates an area for it.
11559 2002-09-03 Borut Razem <borut.razem AT siol.net>
11560 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11561 sdcc/src/pic/glue.c:
11562 introduced atexit() handler for teporay files removal in case of
11563 errors, assertions, ...
11565 2002-08-29 Borut Razem <borut.razem AT siol.net>
11566 * sdcc/support/cpp2/auto-host_vc_in.h:
11567 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11568 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11569 Maybe there is a similar problem with BORLANDC? It should be checked!
11571 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11572 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11573 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11574 was not executed, and the compiler (cl) launched a warning:
11575 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11577 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11578 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11580 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>

11589 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11590 - added Release configuration in VS projects
11591 - review of compiler an linker options
11592 - VC .exe files are generated in bin_vc directory, not to interfere
11593 with binaries generated from other projects (cygwin, mingw, bcc ...)
11595 * sdcc/src/yacc.dsp: added
11597 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11598 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11599 and insert the version number definitions from .version
11601 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11603 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11604 added - genarate auto-host.h using auto-host_vc_in.h as template

11612 2002-08-11 Borut Razem <borut.razem AT siol.net>
11613 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11615 2002-08-10 Borut Razem <borut.razem AT siol.net>
11616 * src/SDCCmain.c (main):
11617 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11618 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11619 The consequence was that some temporary files were not removed.
11622 unification of code in functions tempfilename() and tempfile():
11623 function tempnam() is defined in Visual Studio 6.0 and .NET
11625 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11627 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11628 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11629 - removed compiler command line option /WX: Treats all warnings as errors
11630 - update a list of source files, included into the project
11632 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11633 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11634 changed project type to Generic Project so that can be correcly converted to VS.NET project
11636 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11638 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11640 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11642 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11643 added return 0 statements after assert() to make compiler happy
11645 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11646 added newline in the def file to keep MSC compiler satisfied
11648 * sdcc/src/z80/gen.c:
11649 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11650 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11651 - solved MSC error in function aopDump()
11653 * sdcc_vc.h: define PREFIX as "\\sdcc"
11655 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

11830 * sdcc/src/SDCCloop.c:
11831 Previous fix was not good. basic blocks that have "break" or "return" are
11832 not really partof a loop , but live ranges used in these blocks should
