1594 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1596 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1597 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1599 One basic decision: e.g. src/clean.mk includes further files. In order
1600 to make this work there are two solutions:
1601 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1602 run configure on them. This way they can use
1603 'include $(srcdir)/port-clean.mk'
1604 - always include clean.mk by the Makefile at the same level. To avoid
1605 that `make clean` tries to include and build Makefile.dep the
1606 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1607 implemented, because now even `make uninstall` doesn't create
1608 Makefile.in. clean.mk could be eliminated by pasting it in
1611 * debugger/mcs51/Makefile.in: build own objects from library sources
1612 (SLIB, SDCC) in current directory
1614 * configure, configure.in: renamed --disable-device-lib-build in
1615 --disable-device-lib; added --enable-doc, the required tools are
1616 searched by configure; added result message; the toolchain for the
1617 belonging ports are now only built, if the port is enabled.
1619 * support/regression/*: all output is written in directory gen, because
1620 the fwk and ports directories don't livet in the build tree using vpath
1622 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1623 --disable-device-lib, added --enable-doc, added section VPATH
1625 * sim/ucsim/configure.in,
1626 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1627 z80 are enabled by default
1629 2006-04-24 Raphael Neider <rneider AT web.de>
1631 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1632 to config word, "pic14_"-prefixed some extern functions
1633 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1634 config word has been found
1635 * src/pic/device.h: added prototypes
1636 * src/pic/pcode.c: added "pic14_"-prefix where needed
1637 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
1639 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

1642 (pic14createInterruptVect): moved generating __config directives away

1651 * src/pic/pcoderegs.c (OptimizeRegUsage): do not optimize
1652 registers that have not been assigned proper liveranges,
1653 fixes #1469504 and #1474602,
1654 (pCodeRegOptimizeRegUsage): fixed typo in comment

1900 implemented patch 1120823 Thanks to Willy De la Court (normal
1901 interrupts need an interrupt number now if they are made critical),
1902 and enabled nesting of critical functions though not for gbz80
1903 (genCritical, genEndCritical): added functions
1904 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1905 * src/z80/mappings.i: added "ei" to all mappings

1917 the left operand is shorter than the result (c* = lit-c* + int),
1919 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1922 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1924 * src/.version: increased version number to 2.5.5
1925 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1926 linking is done manually in pic16 port's _linkEdit,
1927 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1928 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1929 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1930 allocate asmop as AOP_ACC,
1931 (aopForRemat): added parameter 'bool result' in function declaration,
1932 (pic16_aopGet): return AOP_ACC when accessing WREG,
1933 (pic16_popGetTempReg): minor modification,

1944 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1945 call to allocReg, not by manually allocating a new one,
1946 (pic16_assignRegisters): now before going through the register
1947 allocating functions mark all registers as free. This eliminates some
1948 side effects resulting from peephole parser done earlier in the backbone
1950 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

2011 'xinst' for initial support for Extended Instruction Support,
2012 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
2013 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
2014 port->fun_prefix anymore (may change later),
2015 (genFunction, genEndFunction): do not store/restore local registers for
2016 _main (this should take care the --main-return command line option in
2018 (genOr): removed some legacy pic-port instructions,
2019 * src/pic16/genarith.c (genAddLit): re-enabled old code because
2020 performing operations with SFR's causes data to be written more than
2021 once to each SFR. Perhaps SFRs should be handled in special cases...
2022 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
2024 * src/pic16/main.c (_process_pragma): stack bound checking did not take
2025 into account for stack starting position,

2029 (deassignLRs): *** perhaps the most important change, old 'for' code
2030 (commented out for reference), didn't account for some registers which
2031 were left marked 'not free' after a pointer operation. The change
2032 reduces register usage a lot in some cases

4311 always available in leading double underscore form. The C99 support is
4312 mostly missing, but it's a start.
4313 * support/regression/tests/bug-227710.c: fixed nonconforming use of
4314 reserved identifier "__data".
4316 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>
4318 * src/mcs51/peeph.def: fixed bug 1170013

4329 2005-03-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4331 * src/port.h (struct PORT),

4359 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
4360 immedDom() returning wrong block; probably fixes bug #1160833)
4362 2005-03-20 Borut Razem <borut.razem AT siol.net>
4364 * support/scripts/inc2h.pl: WIN32 port
4366 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
4368 * device/lib/makefile.in: added abs.c and labs.c
4370 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
4372 * device/include/stdint.h: added
4373 * device/lib/abs.c: added
4374 * device/lib/labs.c: added
4375 * device/include/stdlib.h: added abs() and labs() prototypes
4376 * device/lib/libsdcc.lib: added abs and labs
4377 * device/include/float.h,

4382 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4384 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
4387 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4390 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
4392 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
4394 * device/lib/printf_large.c: removed inline assembly for portability and
4395 readability. Use printf_fast if speed or size are more important.
4396 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4397 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4399 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4401 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4402 prevent compiler warning
4404 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4406 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4407 moved to level 0 and declared as static. Also they are explicit
4408 placed in access bank. This was necessery because some times they
4409 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4410 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4411 optimizations. Currently only compare to unsigned char is implemented,
4412 * src/pic16/gen.c: added fReturnIdx array,
4413 * (struct resolvedIfx) is moved to gen.h and made public,
4414 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4415 * (aopForSym): added an optimization to directly store in stack of
4416 the operand of a SEND iCode,
4417 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4418 but as registers instead (AOP_REG) using the fReturnIdx array,
4419 * (pic16_freeAsmop): remove the freed register from the
4420 _G.sregsAlloc field,
4421 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4422 a compare of 'WREG',
4423 * (pic16_popGetTempRegCond): changed function prototype, now
4424 function takes also a bitVector argument v which holds the current
4425 set of registers that are allocated for stack access by aopForSym,
4426 registers allocated in aopForSym for accessing stack symbols are not
4427 any more part of the functions usedRegs field,
4428 * (genCall): some times aopOp is called for a stack variable to be
4429 send, aopForSym might perform the push, if this is true make sure
4430 that genCall doesn't push the variable twice by testing _G.resDirect,
4431 * (genFunction): changed testing for unspecified interrupt number
4432 from 256 to INTNO_UNSPEC,
4433 * modified selection scheme of frame pointer generation. Previously
4434 if function did use local registers a frame pointer was generated,
4435 now a frame pointer is generated only if function has arguments
4436 (that need PLUSW2 register access), or has stack arguments, or the
4437 compiler is not instructed to omit the frame pointer,
4438 * (genEndFunction): before restoring local registers that were saved
4439 in the function preamble, also restore the registers that *might*
4440 have been allocated for stack access,
4441 * (genRet): removed some old comments,
4442 * (genCmp, the active (RN's) version): added a call to the
4443 pic16_genCmp_special function to perform the compare with a more
4444 robust and optimized way,
4445 * (genInline): a feature has been added in inline code generation,
4446 which allows a wildcard variable substitution when writing inline
4447 assembly. Code is incomplete and experimental therefore undocumented,
4448 * (genCast): changed order of aopOp for result and right to allow
4449 aopForSym to directly load the result if possible,
4450 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4451 perform an optimized compare on some selected special occasions,
4452 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4453 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4454 generate an IVT any more,
4455 * src/pic16/main.c (pic16_optionsTable): added command line option
4457 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4458 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4460 * src/pic16/NOTES: Raphael Neider added in list of active developers
4461 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4462 jumptable_end to prevent bug #,
4463 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4464 inCond and outCond fields,
4465 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4466 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4467 turn off register spilling,
4468 * (packRegsForOneUse): synced with other ports' versions although it
4469 is not used currently,
4470 * (pic16_packRegisters): added an optimization while reading
4471 structure bitfields, some registers may be saved (malloc code is
4472 decreased by 80 bytes)
4474 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4476 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4477 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4478 this can be optimized more?
4480 2005-03-10 Raphael Neider <rneider AT web.de>
4482 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4483 genNearPointerGet): (hopefully) fixed access to bitfields via
4484 pointers (p->bitN = x; and x = p->bitN; failed)
4486 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

4674 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
4675 this might fix SIGSEGVs on MinGW...
4676 * src/SDCCopt.c (killDeadCode): restored original behaviour
4677 (volatile operands might get thrown away though)
4679 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

5118 Adding support for replacing ljmps with sjmps in jumptables
5119 generated for switch statements. For now you need to set the
5120 environment variable SDCC_SJMP_JUMPTABLE to enable this.
5121 Now 4 algorithms for mcs51 jumptable generation are used:
5122 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
5123 addresses loaded pc-relative for up to 112 cases and stack-pushing
5124 target addresses loaded with offset from dptr for up to 256 cases.

5152 to call when a stack overflow occurs,
5153 * (malloc.h): added CVS Id tag,
5154 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
5156 * added libc directory. The current version of LibC contains string
5157 functions, ctype functions and macros and some functions of the
5158 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
5159 be extensively tested in the future. Standard disclaimer here.
5160 Library is not automatically build yet. But one can build it by
5161 invoking 'make' inside the libc directory.

5171 * (genUminusFloat): fixed for pic16, ported code from mcs51,
5172 * (pic16_storeForReturn): optimized return of 0,
5173 * (genCmp): experimental code for new genCmp which uses PIC18's
5174 special compare&skip instructions. Initial tests fail some times
5175 with variables grater than 1 byte in size, so new code is disabled,
5176 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5178 * (genCast): began a fix to optimize the casting of a bit to another
5179 bit, now assigning a bitfield to another bitfield will fail, sorry,
5180 * src/pic16/main.c: disabled the use of lr-support feature,
5181 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

5184 bits with offset (case PO_GPR_BIT),
5185 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in

8202 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
8204 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
8205 loaded with the linker search paths (-L arguments) and the libraries
8206 to be linked with the current source (-l arguments). Changes
8207 currently will affect only the pic16 port.
8208 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8209 include path the port specific paths and port specific libraries,
8210 * gplink command now contains the $3 argument,
8211 * src/pic16/device.h,
8212 * src/pic16/device.c,: structure PIC_device is made public and
8213 renamed to PIC16_device, the same for variable Pics which is renamed

8228 Documenting changes from previous commits.
8229 * configure.in (version 1.56),
8230 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8231 when generating output files to configure the pic16 library,
8232 but now I've commented it out, since gputils aren't installed in the
8233 SF compile farm, so library won't compile
8235 * device/lib/Makefile.in (version 1.56): initially I've added in
8236 target 'all' the prerequestive 'model-pic16' so it compiled the
8237 pic16 library, but now I've commented it out for the same reasons
8239 * added targets 'model-pic16' and 'objects-pic16' to compile the
8241 * added target 'port-specific-objects-pic16' to handle the
8242 generated libraries and copy them into the build/ directory
8243 * added target 'clean-intermediate-pic16' to clean intermediate
8244 files into pic16 directory
8245 * in target 'installdirs' added line to create directory pic16 in
8246 the installation path
8248 * device/include/Makefile.in (version 1.11): in target 'install'
8249 added lines to copy all header files to installation path,
8250 * in target 'installdirs' added line create directory for pic16
8251 headers in the installation path

8267 option so that it actually works. Made it specific to the z80, since
8268 the gbz80 doesn't have these kinds of I/O ports.
8270 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8272 * device/include/z180.h,

8301 weren't marked as being in the access bank,
8303 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
8305 Added portion of GNU PIC Library under the directory
8306 device/include/pic16 and device/lib/pic16. These files
8307 contain the declarations of SFRs for the PIC18Fxx2 devices.
8308 The directory is initialized via configure from toplevel.
8310 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>

8338 all over. Telling LaTeX to be less strict with word spacing
8339 to better keep the right margin. Changed some notes about
8340 maintainance of the ports in section 3.2.1 - is it OK like this?
8342 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

8382 * src/pic16/peeph.def: all peepholes with movff are commented out,
8383 because there is a problem in the pcode peep optimizer,
8384 * src/pic16/ralloc.c: the register allocator can now reuse local

8477 include information about variables allocated to the overlay
8480 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8482 * as/mcs51/lkmain.c: Help about -Y option

8494 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8496 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
8497 (default behaviour).
8499 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8501 A python script to validate compiler diagnostic messages. It can be
8502 used to verify that sdcc complains about bad c source code and
8503 gives a good location of the error.
8504 * support/valdiag/Makefile,
8505 * support/valdiag/valdiag.py,
8506 * support/valdiag/tests/*
8508 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8521 * src/common.h: added ifndef/define/endif macros
8522 around the header file.
8523 Bug reported from Jesus Calvino-Fraga
8525 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8527 * sdcc.spec: updated
8528 * device/include/Makefile.in: don't install CVS directories
8529 * device/lib/Makefile.in: added removal of CVS directories after install
8530 * doc/Makefile: fixed install, added local_icons
8531 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8532 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8533 * src/ds390/gen.c (genRightShift): fixed bug #870788
8534 * src/SDCCast.c (decorateType): fixed bug #870781
8536 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8538 PIC16 port related changes:
8539 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8540 added variable stackPos,
8542 * gen.c: genCall, assignResultValue: added support for
8543 pushing/retrieving function parameters to/from stack,
8544 genFunction,genEndFunction: setup stack frame for the
8546 genAddrOf: will be changed according to bug 863624
8548 * added files genutils.c and genutils.h which contain gen*
8549 debugged and optimised functions extracted from gen.c
8551 * glue.c: added variable 'externs' which holds extern symbols,
8552 pic16emitRegularMap: is modified to properly handle relocatable
8553 symbols under the new scheme,
8554 pic16createInterruptVect: is modified
8555 pic16printPublics: is modified to emit 'global' assembler directives,
8556 added pic16_printExterns to print extern symbols,
8557 pic16glue: initializes stack/frame pointer in the beginning of
8558 the assembly output. Temporary hack, will be corrected later,
8559 because gplink yet does not support stack and SDCC does not
8560 yet support a type of crt0.o object to create the final binary.
8562 * Removed many lines that contain 8051 legacy code.
8563 * The code is finally placed under a 'code' directive.
8564 * Added port specific options.
8566 * _process_pragma: simplified since now we do not need *special*
8567 include file to define SFR registers. But a separate header
8568 will be needed. This will be developed later.
8569 * _pic16_parseOptions: added, parses port specific options:
8570 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8571 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8572 --preplace-udata-with=
8574 * _pic16_setDefaultOptions: modified to initialize section names,
8575 but hack is temporarly out of order since it needs improvement.
8576 * _pic16_genAssemblerPreamble: configuration words are emitted by
8577 their address instead of their name. This part is incomplete and
8578 supports only the 18Fxx2 devices. Other devices will emit an error
8579 during assembly since they do not contain the same set of config
8581 * _pic16_genIVT: is modified,
8583 * pcode.c: added definitions for some hardware registers that are needed
8585 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8586 All PCI entries are updated. Now LFSR is supported.
8587 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8588 * added pic16_newpCodeOpLit2 to support instructions with
8589 two literal arguments
8590 * pic16_pCode2str: corrected code that emits assembler instructions
8591 with two literal operands and those that have an access bit modifier
8592 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8593 this fixes a bug which caused some labels to be lost, when an
8594 assembler directive was added, i.e. banksel,
8595 * pic16_FixRegisterBanking: improved logic that causes the insertion
8597 * InlineFunction: functions that are called once, are not any more
8598 inlined. This can be a port option in the future,
8600 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8602 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8603 hold the corresponding uninitialized symbols,
8604 * pic16_allocProcessorRegister: registers have explicit marked the
8606 * pic16_allocInternalRegister: registers are explicit marked as
8608 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8609 processing list, so bit registers were lost,
8612 * ralloc.h: added field 'accessBank' and original symbol operand
8613 in register definition,
8614 * removed the field isMapped from register definition,
8616 ** Several functions have been removed from various sources:
8617 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8618 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8619 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8620 pic16_assignRelocatableRegisters
8622 ** others have been introduced:
8623 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8624 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8626 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8628 * support/scripts/inc2h.pl: changed definition of BIT_AT
8629 to emit 'sbit at' instead of 'bit at'. This was a request.
8631 PIC16 port related preliminary changes:
8632 * gen.c: prefixed function popRegFromString with
8633 pic16_ and all references to it corrected
8634 * pcode.c: all pic16_pc_* hardware registers prefixed
8635 with underscore (_),
8636 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8637 * ralloc.c: newReg(): when register is REG_SFR then
8638 set address to rIdx,
8639 pic16_allocProcessorRegister(): marks register wasUsed=0
8640 pic16_writeUsedRegs(): added a call to assign processor
8641 registers via pic16_assignFixedRegisters
8643 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8645 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8646 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8647 variables in unused register banks. Also the SSEG is placed
8648 wherever there is enough space for it, and IDATA can be anywhere
8649 in internal RAM. For now compile using -Wl-Y[stack_size].
8650 The mem file is different for this option as well, since it
8651 makes no sense of talking about DSEG lenght.
8653 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8655 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8656 in certain cases, e.g. when ROM assignment, patch provided
8657 from Albert den Haan.
8659 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8801 SDCC_NOGENRAMCLEAR to disable this.
8802 * src/mcs51/peephole.def,
8803 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
8804 (allows non-interrupt and interrupt code to safely compete for a resource
8805 without the non-interrupt code having to disable interrupts)
8807 2003-12-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8809 * src/SDCCicode.c (geniCodeAdd),

8829 2003-12-11 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8831 * src/z80/ralloc.c: set DISABLE_PACK_HL = 1 as a temporary fix to bug #855165
8833 2003-12-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8901 revision 1.188 (access to fields of a structure at an absolute address);
8902 it breaks with bitfields, extern declarations, and gcse analysis.
8903 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
8904 could be assigned through a pointer, so don't complain.

9682 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9683 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9684 type for bits was changed. It resulted in bit variables becoming
9685 global, which is not permitted in PIC 14 assembly output.

9702 A few small changes that speed up the peephole optimizer.
9706 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9708 Try to make the peephole optimizer smarter by maintaining
9709 an association between the assembly source code and the
9710 iCodes that originated them. Put this information to use
9711 with a new peephole rule condition "notVolatile" so that
9712 the rules can be aggressive yet still safe.
9717 * src/mcs51/peeph.def
9719 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9723 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9724 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9725 if the left or right operand symbols have the accuse flag set.
9727 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9729 Changed the type of the result of the ! (NOT) operator to char;
9730 previously it returned the same type as the source. This allows
9731 us to eliminate all the genFloatNot functions (all of its target
9732 implementations were very buggy) since !float can use the same
9735 * src/SDCCicode.c (ast2iCode): ! returns char

9744 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9745 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9746 during interrupts. Ensure WSAVE is located at a shared bank address.
9747 2. Fixed page selection in some places
9748 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9749 the registers name strings.
9750 4. Fixed "signed / unsigned compare" compiler warnings.
9751 5. The PIC port manages its own allocation of the general purpose
9752 registers, but makes no attempt to reuse them. As a result when
9753 compiling it soon runs out of general purpose registers. Some
9754 additional code was added to the files pcode.c and device.c to walk
9755 through the function call tree and rename the registers so that they
9765 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9766 genPlus() & genMinus() when the result is the same as left or right
9768 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9772 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9774 Made bitfield a distinct type from bit so that bitfields
9775 convert as per ANSI C and bits retain their traditional
9776 boolean style behaviour. Implemented bitfield support in
9784 * src/ds390/gen.c: bit v bitfield split
9785 * src/z80/gen.c: New support for bitfields
9786 * support/regression/tests/bitfields.c: reenabled z80,
9789 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9791 Rules 246.x, 247.x relate to bitfields, the others speed up
9792 access to xdata mapped I/O devices.
9794 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9796 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9798 Cleaned up genPackBits and genUnpackBits and added two helper
9799 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9800 for literal assignments in genPackBits (thanks to Frieder for
9806 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9808 Fixed bug #748310 (pointer to function type mishandled when the
9809 function name is omitted). Also fixed a SIGSEGV when a function
9810 attribute (reentrant, etc) is used on a non-function or on a
9811 function but misplaced before the parameter list.
9813 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9815 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

9841 omitted, the function will not automatically be given an entry
9842 in the interrupt vector table (similar to #pragma NOIV, but
9843 less syntacticly kludgy). The interrupt number is also now
9844 range checked. Also fixed a bug in the high order bit example

9912 * src/SDCCval.c (valDiv, valMod): fixed signdness
9913 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
9914 signedness of modulo, left and right shift

10362 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
10364 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
10365 it can be defined with CFLAGS when running configure
10366 * src/SDCCmain.c: fixed compiling + linking with object files
10368 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
10370 * configure.in: configure for pic16 port,
10371 added --disable-pic16-port
10372 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
10373 * src/SDCCmain.c: linkOptions is changed to set *,
10374 added if/endif conditional macros to remove options help
10375 messages from optionsTable when a port is not configured, added
10376 support for the PIc16 port in the ports table, when executing
10377 the compiler with no port specified on command line, a default
10378 port is selected with the new macro DEFAULT_PORT which is
10379 defined in port.h, in setDefaultOptions() linkOptions is removed
10380 from initialization assignment, since now it is a set,
10381 parseCmdLine uses setParseWithComma for linkOptions, in
10382 linkEdit() linkOptions are accessed with new function indexSet()
10383 which returns the i'th item of a set variable. See SDCCset.c, in
10384 linkEdit() when calling buildCmdLine(), added linkOptions as
10385 last argument. Now users can pass arguments to gplink via the
10386 -Wl option, main() uses pic16glue() to glue up pic16 programs
10387 * src/SDCCpeeph.c: various changes to support pic16
10388 * src/SDCCset.c: added function void *indexSet(set *, int) to

10398 * src/pic16/glue.c: commented out some error producing lines
10399 * src/pic16/main.c: __config directives are commented out to stop
10400 gpasm complaining and test the linkage with gplink, _linkCmd and
10401 _asmCmd changed to be more gplink and gpasm friendly
10402 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10403 produced an error when parsed, peep rule 12 is added to utilize
10404 movff, but it is commented out since the pCode does not support
10405 yet a command with 2 address arguments

11467 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
11468 * src/mcs51/main.c: removed {bindir}{sep} from aslink
11470 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11472 * in /sdcc/as/mcs51/ changed these files in order to create an
11473 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11474 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11475 following files to include the previous two files: aslink.dsp,
11476 Makefile.aslink, Makefile.bcc, and Makefile.in.
11478 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11479 .adb instead of .cdb
11481 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11483 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11484 value from option --iram-size.
11486 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11488 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11491 2002-09-18 <wiml AT hhhh.org>
11493 * SDCClrange.h: exposed setFromRange() and setToRange()
11494 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11495 packRegsForAccUse() (bug 542397)
11496 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11497 multiple times and emitting the fetch operations more than once
11498 added aopGetUsesAcc() function to allow binary operators to
11499 fetch their operands in the correct order; made genMinus() emit
11500 compact code for X = LITERAL - Y
11502 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11503 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11504 sprintf() in line 1267.
11506 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11507 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11510 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11511 Changes to aslink (All the changes are marked with 'JCF'):
11513 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11516 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11517 area BSEG. Also moves, if possible, the DATA area down into the internal
11518 ram so more space is available.
11520 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11523 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11524 not bytes. Function summary() which creates a memory usage summary
11525 file with extension .mem. Reports of overlaping stack and small stack
11526 size. If the space for the stack is less than 16 bytes aslink trows a
11529 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11530 the 8051. Option 'y' for memory summary output file.
11532 Changes to sdcc (All the changes are marked with 'JCF'):
11534 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11536 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11537 overlaying area for it (uses RegBankUsed[4]).
11539 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11540 bank zero as used by default. By default aslink locates the stack
11541 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11542 the creation of the .mem file. Delegates the allocation of data area
11543 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11544 the begining of the stack area to aslink.
11546 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11547 glue() in SDCCglue.c creates an area for it.
11549 2002-09-03 Borut Razem <borut.razem AT siol.net>
11550 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11551 sdcc/src/pic/glue.c:
11552 introduced atexit() handler for teporay files removal in case of
11553 errors, assertions, ...
11555 2002-08-29 Borut Razem <borut.razem AT siol.net>
11556 * sdcc/support/cpp2/auto-host_vc_in.h:
11557 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11558 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11559 Maybe there is a similar problem with BORLANDC? It should be checked!
11561 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11562 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11563 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11564 was not executed, and the compiler (cl) launched a warning:
11565 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11567 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11568 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11570 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11571 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11573 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11574 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11575 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11576 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11577 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11578 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11579 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11580 - added Release configuration in VS projects
11581 - review of compiler an linker options
11582 - VC .exe files are generated in bin_vc directory, not to interfere
11583 with binaries generated from other projects (cygwin, mingw, bcc ...)
11585 * sdcc/src/yacc.dsp: added
11587 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11588 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11589 and insert the version number definitions from .version
11591 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11593 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11594 added - genarate auto-host.h using auto-host_vc_in.h as template
11597 removed from CVS, generated automatically
11599 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11600 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11602 2002-08-11 Borut Razem <borut.razem AT siol.net>
11603 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11605 2002-08-10 Borut Razem <borut.razem AT siol.net>
11606 * src/SDCCmain.c (main):
11607 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11608 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11609 The consequence was that some temporary files were not removed.

11821 Previous fix was not good. basic blocks that have "break" or "return" are
11822 not really partof a loop , but live ranges used in these blocks should
