1375 * install-sh: fix bug #1204398 by setting umask 0022
1376 * device/lib/Makefile: separate build of z80 and gbz80 lib
1378 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1380 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1381 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1383 One basic decision: e.g. src/clean.mk includes further files. In order
1384 to make this work there are two solutions:
1385 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1386 run configure on them. This way they can use
1387 'include $(srcdir)/port-clean.mk'
1388 - always include clean.mk by the Makefile at the same level. To avoid
1389 that `make clean` tries to include and build Makefile.dep the
1390 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1391 implemented, because now even `make uninstall` doesn't create
1392 Makefile.in. clean.mk could be eliminated by pasting it in
1395 * debugger/mcs51/Makefile.in: build own objects from library sources
1396 (SLIB, SDCC) in current directory
1398 * configure, configure.in: renamed --disable-device-lib-build in
1399 --disable-device-lib; added --enable-doc, the required tools are
1400 searched by configure; added result message; the toolchain for the
1401 belonging ports are now only built, if the port is enabled.
1403 * support/regression/*: all output is written in directory gen, because
1404 the fwk and ports directories don't livet in the build tree using vpath
1406 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1407 --disable-device-lib, added --enable-doc, added section VPATH
1409 * sim/ucsim/configure.in,
1410 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1411 z80 are enabled by default
1413 2006-04-24 Raphael Neider <rneider AT web.de>
1415 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1416 to config word, "pic14_"-prefixed some extern functions
1417 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1418 config word has been found
1419 * src/pic/device.h: added prototypes

1728 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1729 call to allocReg, not by manually allocating a new one,
1730 (pic16_assignRegisters): now before going through the register
1731 allocating functions mark all registers as free. This eliminates some
1732 side effects resulting from peephole parser done earlier in the backbone

1784 2006-03-06 Borut Razem <borut.razem AT siol.net>
1786 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
1787 made the linker quiet
1789 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
1791 * src/pic16/gen.c (genPcall): fixed bug #1443644
1792 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1793 which dumps before the function entry point a data byte which represents
1794 the number of the local variables used by the specified function, added
1795 'xinst' for initial support for Extended Instruction Support,
1796 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1797 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1798 port->fun_prefix anymore (may change later),
1799 (genFunction, genEndFunction): do not store/restore local registers for
1800 _main (this should take care the --main-return command line option in
1802 (genOr): removed some legacy pic-port instructions,
1803 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1804 performing operations with SFR's causes data to be written more than
1805 once to each SFR. Perhaps SFRs should be handled in special cases...
1806 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1808 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1809 into account for stack starting position,
1810 (struct OPTIONS pic16_optionsTable): added command line argument
1811 --extended or -y for Extended Instruction Support,
1812 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1813 (deassignLRs): *** perhaps the most important change, old 'for' code
1814 (commented out for reference), didn't account for some registers which
1815 were left marked 'not free' after a pointer operation. The change
1816 reduces register usage a lot in some cases

4089 * src/SDCCglobal.h (struct options),
4091 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
4092 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
4093 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
4094 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
4095 always available in leading double underscore form. The C99 support is
4096 mostly missing, but it's a start.
4097 * support/regression/tests/bug-227710.c: fixed nonconforming use of

4176 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
4178 * device/lib/printf_large.c: removed inline assembly for portability and
4179 readability. Use printf_fast if speed or size are more important.
4180 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4181 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4183 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4185 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4186 prevent compiler warning
4188 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4190 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4191 moved to level 0 and declared as static. Also they are explicit
4192 placed in access bank. This was necessery because some times they
4193 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4194 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4195 optimizations. Currently only compare to unsigned char is implemented,
4196 * src/pic16/gen.c: added fReturnIdx array,
4197 * (struct resolvedIfx) is moved to gen.h and made public,
4198 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4199 * (aopForSym): added an optimization to directly store in stack of
4200 the operand of a SEND iCode,
4201 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4202 but as registers instead (AOP_REG) using the fReturnIdx array,
4203 * (pic16_freeAsmop): remove the freed register from the
4204 _G.sregsAlloc field,
4205 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4206 a compare of 'WREG',
4207 * (pic16_popGetTempRegCond): changed function prototype, now
4208 function takes also a bitVector argument v which holds the current
4209 set of registers that are allocated for stack access by aopForSym,
4210 registers allocated in aopForSym for accessing stack symbols are not
4211 any more part of the functions usedRegs field,
4212 * (genCall): some times aopOp is called for a stack variable to be
4213 send, aopForSym might perform the push, if this is true make sure
4214 that genCall doesn't push the variable twice by testing _G.resDirect,
4215 * (genFunction): changed testing for unspecified interrupt number
4216 from 256 to INTNO_UNSPEC,
4217 * modified selection scheme of frame pointer generation. Previously
4218 if function did use local registers a frame pointer was generated,
4219 now a frame pointer is generated only if function has arguments
4220 (that need PLUSW2 register access), or has stack arguments, or the
4221 compiler is not instructed to omit the frame pointer,
4222 * (genEndFunction): before restoring local registers that were saved
4223 in the function preamble, also restore the registers that *might*
4224 have been allocated for stack access,
4225 * (genRet): removed some old comments,
4226 * (genCmp, the active (RN's) version): added a call to the
4227 pic16_genCmp_special function to perform the compare with a more
4228 robust and optimized way,
4229 * (genInline): a feature has been added in inline code generation,
4230 which allows a wildcard variable substitution when writing inline
4231 assembly. Code is incomplete and experimental therefore undocumented,
4232 * (genCast): changed order of aopOp for result and right to allow
4233 aopForSym to directly load the result if possible,
4234 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4235 perform an optimized compare on some selected special occasions,
4236 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4237 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4238 generate an IVT any more,
4239 * src/pic16/main.c (pic16_optionsTable): added command line option
4241 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4242 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4244 * src/pic16/NOTES: Raphael Neider added in list of active developers
4245 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4246 jumptable_end to prevent bug #,
4247 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4248 inCond and outCond fields,
4249 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4250 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4251 turn off register spilling,
4252 * (packRegsForOneUse): synced with other ports' versions although it
4253 is not used currently,
4254 * (pic16_packRegisters): added an optimization while reading
4255 structure bitfields, some registers may be saved (malloc code is
4256 decreased by 80 bytes)
4258 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4260 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4261 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4262 this can be optimized more?
4264 2005-03-10 Raphael Neider <rneider AT web.de>
4266 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4267 genNearPointerGet): (hopefully) fixed access to bitfields via
4268 pointers (p->bitN = x; and x = p->bitN; failed)
4270 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
4272 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

4311 2005-02-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4313 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
4314 to keep the correct label reference count when adding/removing references

4900 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4902 Adding support for replacing ljmps with sjmps in jumptables
4903 generated for switch statements. For now you need to set the
4904 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4905 Now 4 algorithms for mcs51 jumptable generation are used:
4906 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4907 addresses loaded pc-relative for up to 112 cases and stack-pushing
4908 target addresses loaded with offset from dptr for up to 256 cases.

4938 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4940 * added libc directory. The current version of LibC contains string
4941 functions, ctype functions and macros and some functions of the
4942 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4943 be extensively tested in the future. Standard disclaimer here.
4944 Library is not automatically build yet. But one can build it by
4945 invoking 'make' inside the libc directory.
4946 * added ADC library under libio. Preliminary version yet.

4952 temporary registers, its a buggy feature and will be removed,
4953 * (pic16_popGet): set register instance field in AOP_CRY,
4954 * (pic16_outBitC): fixed for results in size greater than 1,
4955 * (genUminusFloat): fixed for pic16, ported code from mcs51,
4956 * (pic16_storeForReturn): optimized return of 0,
4957 * (genCmp): experimental code for new genCmp which uses PIC18's
4958 special compare&skip instructions. Initial tests fail some times
4959 with variables grater than 1 byte in size, so new code is disabled,
4960 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4962 * (genCast): began a fix to optimize the casting of a bit to another
4963 bit, now assigning a bitfield to another bitfield will fail, sorry,
4964 * src/pic16/main.c: disabled the use of lr-support feature,
4965 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

4968 bits with offset (case PO_GPR_BIT),
4969 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
4971 * (isBankInstruction): modified to return 0 for no banking instruction,
4972 and 1 for banking instruction,
4973 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4974 caused stop processing pCodes after a inline assembly block,
4975 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
4976 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
4977 registers when it shouldn't,
4978 * src/pic16/ralloc.c (allocReg): add preliminary support for
4979 supporting a limited set of temporary registers,
4981 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4983 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
4984 genDataPointerSet): ensure assignments always copy in MSB to LSB
4986 (loadRegFromAop): recognize CLRH optimization,
4987 (genFunction): optimize RECEIVE iCodes in reentrant functions
4989 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4991 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

7900 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
7902 * src/SDCCast.c: added an additional type flow in decorateType() of
7903 opposite direction, see feature request #860006; it's enabled at runtime
7904 by setting the environment variable SDCC_NEWTYPEFLOW

7988 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
7989 loaded with the linker search paths (-L arguments) and the libraries
7990 to be linked with the current source (-l arguments). Changes
7991 currently will affect only the pic16 port.
7992 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7993 include path the port specific paths and port specific libraries,
7994 * gplink command now contains the $3 argument,
7995 * src/pic16/device.h,
7996 * src/pic16/device.c,: structure PIC_device is made public and
7997 renamed to PIC16_device, the same for variable Pics which is renamed

8012 Documenting changes from previous commits.
8013 * configure.in (version 1.56),
8014 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8015 when generating output files to configure the pic16 library,
8016 but now I've commented it out, since gputils aren't installed in the
8017 SF compile farm, so library won't compile
8019 * device/lib/Makefile.in (version 1.56): initially I've added in
8020 target 'all' the prerequestive 'model-pic16' so it compiled the
8021 pic16 library, but now I've commented it out for the same reasons
8023 * added targets 'model-pic16' and 'objects-pic16' to compile the
8025 * added target 'port-specific-objects-pic16' to handle the
8026 generated libraries and copy them into the build/ directory
8027 * added target 'clean-intermediate-pic16' to clean intermediate
8028 files into pic16 directory
8029 * in target 'installdirs' added line to create directory pic16 in

8033 added lines to copy all header files to installation path,
8034 * in target 'installdirs' added line create directory for pic16
8035 headers in the installation path

8332 * added files genutils.c and genutils.h which contain gen*
8333 debugged and optimised functions extracted from gen.c
8335 * glue.c: added variable 'externs' which holds extern symbols,
8336 pic16emitRegularMap: is modified to properly handle relocatable
8337 symbols under the new scheme,
8338 pic16createInterruptVect: is modified
8339 pic16printPublics: is modified to emit 'global' assembler directives,
8340 added pic16_printExterns to print extern symbols,
8341 pic16glue: initializes stack/frame pointer in the beginning of
8342 the assembly output. Temporary hack, will be corrected later,
8343 because gplink yet does not support stack and SDCC does not
8344 yet support a type of crt0.o object to create the final binary.
8346 * Removed many lines that contain 8051 legacy code.
8347 * The code is finally placed under a 'code' directive.
8348 * Added port specific options.
8350 * _process_pragma: simplified since now we do not need *special*
8351 include file to define SFR registers. But a separate header
8352 will be needed. This will be developed later.
8353 * _pic16_parseOptions: added, parses port specific options:
8354 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8355 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8356 --preplace-udata-with=
8358 * _pic16_setDefaultOptions: modified to initialize section names,
8359 but hack is temporarly out of order since it needs improvement.
8360 * _pic16_genAssemblerPreamble: configuration words are emitted by
8361 their address instead of their name. This part is incomplete and
8362 supports only the 18Fxx2 devices. Other devices will emit an error
8363 during assembly since they do not contain the same set of config
8365 * _pic16_genIVT: is modified,
8367 * pcode.c: added definitions for some hardware registers that are needed
8369 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8370 All PCI entries are updated. Now LFSR is supported.
8371 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8372 * added pic16_newpCodeOpLit2 to support instructions with
8373 two literal arguments
8374 * pic16_pCode2str: corrected code that emits assembler instructions
8375 with two literal operands and those that have an access bit modifier
8376 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8377 this fixes a bug which caused some labels to be lost, when an
8378 assembler directive was added, i.e. banksel,
8379 * pic16_FixRegisterBanking: improved logic that causes the insertion
8381 * InlineFunction: functions that are called once, are not any more
8382 inlined. This can be a port option in the future,
8384 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8386 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8387 hold the corresponding uninitialized symbols,
8388 * pic16_allocProcessorRegister: registers have explicit marked the
8390 * pic16_allocInternalRegister: registers are explicit marked as
8392 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8393 processing list, so bit registers were lost,
8396 * ralloc.h: added field 'accessBank' and original symbol operand
8397 in register definition,
8398 * removed the field isMapped from register definition,
8400 ** Several functions have been removed from various sources:
8401 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8402 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8403 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8404 pic16_assignRelocatableRegisters
8406 ** others have been introduced:
8407 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8408 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8410 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8412 * support/scripts/inc2h.pl: changed definition of BIT_AT
8413 to emit 'sbit at' instead of 'bit at'. This was a request.
8415 PIC16 port related preliminary changes:
8416 * gen.c: prefixed function popRegFromString with
8417 pic16_ and all references to it corrected
8418 * pcode.c: all pic16_pc_* hardware registers prefixed
8419 with underscore (_),
8420 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8421 * ralloc.c: newReg(): when register is REG_SFR then
8422 set address to rIdx,
8423 pic16_allocProcessorRegister(): marks register wasUsed=0
8424 pic16_writeUsedRegs(): added a call to assign processor
8425 registers via pic16_assignFixedRegisters
8427 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8429 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8430 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8431 variables in unused register banks. Also the SSEG is placed
8432 wherever there is enough space for it, and IDATA can be anywhere
8433 in internal RAM. For now compile using -Wl-Y[stack_size].
8434 The mem file is different for this option as well, since it
8435 makes no sense of talking about DSEG lenght.
8437 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8439 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8440 in certain cases, e.g. when ROM assignment, patch provided
8441 from Albert den Haan.
8443 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8682 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8684 * src/SDCCast.c (decorateType): disabled a transformation I added in
8685 revision 1.188 (access to fields of a structure at an absolute address);
8686 it breaks with bitfields, extern declarations, and gcse analysis.
8687 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
8688 could be assigned through a pointer, so don't complain.
8689 * src/SDCCast.c (astErrors),
8691 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

8791 2003-11-13 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8793 * src/mcs51/main.c: started fixing bug #737001 (SDCC not clearing
8794 uninitialized variables) for the mcs51. Set environment variable

9445 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
9446 fetching of the pointer
9447 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
9448 copied from genNearPointerSet()
9449 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
9450 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
9451 If they pop r0/r1 they must be called in the opposite order than aopOp().

9466 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9467 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9468 type for bits was changed. It resulted in bit variables becoming
9469 global, which is not permitted in PIC 14 assembly output.
9471 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9473 * doc/sdccman.lyx: various additions and updates. Rearranged sections

9486 A few small changes that speed up the peephole optimizer.
9490 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9492 Try to make the peephole optimizer smarter by maintaining
9493 an association between the assembly source code and the
9494 iCodes that originated them. Put this information to use
9495 with a new peephole rule condition "notVolatile" so that
9496 the rules can be aggressive yet still safe.
9501 * src/mcs51/peeph.def
9503 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9507 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9508 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9509 if the left or right operand symbols have the accuse flag set.
9511 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9513 Changed the type of the result of the ! (NOT) operator to char;
9514 previously it returned the same type as the source. This allows
9515 us to eliminate all the genFloatNot functions (all of its target
9516 implementations were very buggy) since !float can use the same
9519 * src/SDCCicode.c (ast2iCode): ! returns char

9528 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9529 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9530 during interrupts. Ensure WSAVE is located at a shared bank address.
9531 2. Fixed page selection in some places
9532 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9533 the registers name strings.
9534 4. Fixed "signed / unsigned compare" compiler warnings.
9535 5. The PIC port manages its own allocation of the general purpose
9536 registers, but makes no attempt to reuse them. As a result when
9537 compiling it soon runs out of general purpose registers. Some
9538 additional code was added to the files pcode.c and device.c to walk
9539 through the function call tree and rename the registers so that they
9549 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9550 genPlus() & genMinus() when the result is the same as left or right

9556 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9558 Made bitfield a distinct type from bit so that bitfields
9559 convert as per ANSI C and bits retain their traditional
9560 boolean style behaviour. Implemented bitfield support in
9568 * src/ds390/gen.c: bit v bitfield split
9569 * src/z80/gen.c: New support for bitfields
9570 * support/regression/tests/bitfields.c: reenabled z80,
9573 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9575 Rules 246.x, 247.x relate to bitfields, the others speed up
9576 access to xdata mapped I/O devices.
9578 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9580 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9582 Cleaned up genPackBits and genUnpackBits and added two helper
9583 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9584 for literal assignments in genPackBits (thanks to Frieder for
9590 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9592 Fixed bug #748310 (pointer to function type mishandled when the
9593 function name is omitted). Also fixed a SIGSEGV when a function
9594 attribute (reentrant, etc) is used on a non-function or on a
9595 function but misplaced before the parameter list.
9597 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9599 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
9600 * support/Util/SDCCerr.h,
9601 * support/Util/SDCCerr.c: Added func attr misuse error msg
9603 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
9605 Fixed bug #787649 by anonymous
9606 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr

9622 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9624 Made the constant following the "interrupt" keyword optional. If
9625 omitted, the function will not automatically be given an entry
9626 in the interrupt vector table (similar to #pragma NOIV, but
9627 less syntacticly kludgy). The interrupt number is also now
9628 range checked. Also fixed a bug in the high order bit example

9636 * support/Util/SDCCerr.h
9639 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
9641 * src/SDCCcse.c (algebraicOpts): fix bug converting op from value to type
9642 * src/SDCCicode.c (operandOperation): rewritten some ops
9643 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
9644 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9646 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9647 be re-activated by defining REDUCE_LITERALS)
9648 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
9649 unsigned, but are signed by default
9650 * src/SDCCval.c (constVal): rearranged
9651 * src/SDCCval.c (valMod): preliminary fix
9652 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9694 constants are unsigned; added recognition of "u" flag for unsigned
9695 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
9696 * src/SDCCval.c (valDiv, valMod): fixed signdness
9697 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
9698 signedness of modulo, left and right shift

10158 added if/endif conditional macros to remove options help
10159 messages from optionsTable when a port is not configured, added
10160 support for the PIc16 port in the ports table, when executing
10161 the compiler with no port specified on command line, a default
10162 port is selected with the new macro DEFAULT_PORT which is
10163 defined in port.h, in setDefaultOptions() linkOptions is removed
10164 from initialization assignment, since now it is a set,
10165 parseCmdLine uses setParseWithComma for linkOptions, in
10166 linkEdit() linkOptions are accessed with new function indexSet()
10167 which returns the i'th item of a set variable. See SDCCset.c, in
10168 linkEdit() when calling buildCmdLine(), added linkOptions as
10169 last argument. Now users can pass arguments to gplink via the
10170 -Wl option, main() uses pic16glue() to glue up pic16 programs

10184 gpasm complaining and test the linkage with gplink, _linkCmd and
10185 _asmCmd changed to be more gplink and gpasm friendly
10186 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10187 produced an error when parsed, peep rule 12 is added to utilize
10188 movff, but it is commented out since the pCode does not support
10189 yet a command with 2 address arguments
10191 2003-05-18 <johan AT balder>
10193 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

11211 2003-01-07 <johan AT balder>
11213 * src/SDCCast.c (decorateType): fixed bug #600035
11215 2003-01-07 Bernhard Held <bernhard AT bernhardheld.de>
11216 * as/mcs51/lkmem.c: added several l-modifiers to printf to remove warnings
11217 * as/mcs51/lkaomf51.c: #include <ctype.h> to remove warnings
11218 * src/pic/main.c (_hasNativeMulFor): outcommented unused variables to remove warnings
11219 * src/pic/pcode.c: outcommented unused variable to remove warnings
11220 * src/pic/ralloc.c: outcommented unused variable to remove warnings
11222 2003-01-06 <karl AT turbobit.com>
11223 * sim/ucsim/cmd.src/command.cc: fixed so "break xram r 0x7654" works again in
11226 2003-01-06 <johan AT balder>
11228 * src/SDCCicode.c: fixed array add
11230 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
11231 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
11232 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
11234 2003-01-04 <johan AT balder>
11236 * src/SDCCval.c (getNelements): fixed the initialized array of structures
11238 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11239 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
11241 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
11242 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
11243 * support/regression/tests/bug-524697.c: fit mem usage into 8032
11245 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
11246 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
11248 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
11249 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
11251 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
11252 * src/mcs51/main.c: removed {bindir}{sep} from aslink
11254 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11256 * in /sdcc/as/mcs51/ changed these files in order to create an
11257 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11258 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11259 following files to include the previous two files: aslink.dsp,
11260 Makefile.aslink, Makefile.bcc, and Makefile.in.
11262 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11263 .adb instead of .cdb
11265 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11267 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11268 value from option --iram-size.
11270 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11272 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11275 2002-09-18 <wiml AT hhhh.org>
11277 * SDCClrange.h: exposed setFromRange() and setToRange()
11278 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11279 packRegsForAccUse() (bug 542397)
11280 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11281 multiple times and emitting the fetch operations more than once
11282 added aopGetUsesAcc() function to allow binary operators to
11283 fetch their operands in the correct order; made genMinus() emit
11284 compact code for X = LITERAL - Y
11286 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11287 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11288 sprintf() in line 1267.
11290 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11291 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11294 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11295 Changes to aslink (All the changes are marked with 'JCF'):
11297 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11300 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11301 area BSEG. Also moves, if possible, the DATA area down into the internal
11302 ram so more space is available.
11304 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11307 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11308 not bytes. Function summary() which creates a memory usage summary
11309 file with extension .mem. Reports of overlaping stack and small stack
11310 size. If the space for the stack is less than 16 bytes aslink trows a
11313 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11314 the 8051. Option 'y' for memory summary output file.
11316 Changes to sdcc (All the changes are marked with 'JCF'):
11318 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11320 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11321 overlaying area for it (uses RegBankUsed[4]).
11323 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11324 bank zero as used by default. By default aslink locates the stack
11325 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11326 the creation of the .mem file. Delegates the allocation of data area
11327 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11328 the begining of the stack area to aslink.
11330 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11331 glue() in SDCCglue.c creates an area for it.
11333 2002-09-03 Borut Razem <borut.razem AT siol.net>
11334 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11335 sdcc/src/pic/glue.c:
11336 introduced atexit() handler for teporay files removal in case of
11337 errors, assertions, ...
11339 2002-08-29 Borut Razem <borut.razem AT siol.net>
11340 * sdcc/support/cpp2/auto-host_vc_in.h:
11341 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11342 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11343 Maybe there is a similar problem with BORLANDC? It should be checked!
11345 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11346 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11347 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11348 was not executed, and the compiler (cl) launched a warning:
11349 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11351 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11352 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11354 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11355 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11357 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11358 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11359 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11360 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11361 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11362 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11363 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11364 - added Release configuration in VS projects
11365 - review of compiler an linker options
11366 - VC .exe files are generated in bin_vc directory, not to interfere
11367 with binaries generated from other projects (cygwin, mingw, bcc ...)
11369 * sdcc/src/yacc.dsp: added
11371 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11372 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11373 and insert the version number definitions from .version
11375 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11377 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11378 added - genarate auto-host.h using auto-host_vc_in.h as template
11381 removed from CVS, generated automatically
11383 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11384 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11386 2002-08-11 Borut Razem <borut.razem AT siol.net>
11387 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11389 2002-08-10 Borut Razem <borut.razem AT siol.net>
11390 * src/SDCCmain.c (main):
11391 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11392 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11393 The consequence was that some temporary files were not removed.
11396 unification of code in functions tempfilename() and tempfile():
11397 function tempnam() is defined in Visual Studio 6.0 and .NET
11399 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11401 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11402 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11403 - removed compiler command line option /WX: Treats all warnings as errors
11404 - update a list of source files, included into the project
11406 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11407 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11408 changed project type to Generic Project so that can be correcly converted to VS.NET project
11410 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11412 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11414 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11416 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11417 added return 0 statements after assert() to make compiler happy
11419 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11420 added newline in the def file to keep MSC compiler satisfied
11422 * sdcc/src/z80/gen.c:
11423 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11424 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11425 - solved MSC error in function aopDump()
11427 * sdcc_vc.h: define PREFIX as "\\sdcc"
11429 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
11430 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

11433 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
11434 - Rewrote the register banking algorithm.
11435 - Added pCode live-range analysis to registers (for now, only non-used and
11436 singly-used registers optimized away)
11438 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
11440 * support/scripts/inc2h.pl Kevin L. Pauba <klpauba AT cox.net> submitted this perl script for converting MicroChip include files into SDCC Pic include files.

11459 * src/z80/ralloc.c (packRegisters): Disabled pack HL use for GB as it's broken.
11461 * src/z80/peeph.def: Added transpose redundent load rule.
11463 * src/z80/main.c: Added force callee saves for jaune.
11465 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
11467 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
11469 2002-03-28 Johan Knol <johan AT balder>
11471 * src/SDCCval.c: fixed bug #532436
11473 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11475 Added "char *Processor" field to the port structure.
11478 Added -p option. Allows port dependent processor to be specified.
11481 Initialized the new field char *Processor field to NULL in all ports
11484 Compiler generated registers for interrupt context saving
11485 were not getting allocated.
11487 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
11490 Fixed left shift. Will promote the left side of a left shift
11491 if a) left shifting more than size of operand or b) when assigned
11492 to something size > size of left side
11494 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11496 tons of changes. Register allocation has been
11497 rewritten. Added customization for the various PICs. Flow
11498 analysis is restructured. ...
11500 * src/pic/device.h:
11503 * src/pic/device.c:
11504 Added. device.c is a PIC port hack to accomodate variations
11507 2002-03-13 Michael Hope <michaelh AT vroom>
11509 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
11511 2002-03-04 johanknol <johanknol AT manik>
11513 * /src/SDCCval.c: fixed
11515 const unsigned char arr[][2] = { { 0, 1 } };
11516 t18.c:1: error: Initializer element is not constant

11602 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
11604 * sdcc/src/SDCCloop.c:
11605 Previous fix was not good. basic blocks that have "break" or "return" are
11606 not really partof a loop , but live ranges used in these blocks should
11607 be live thru the entire loop, so set partOfLoop but don't add them to
11610 2002-02-21 <johan AT FRIJA>
11612 * src/SDCCcse.c: fixed bug #514308
11614 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
11617 Fixed BUG #519583. If a conditional block ended in a return/break
11618 statement inside a loop, it was not being considered part of the loop.
11620 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
11622 2002-02-10 Karl Bongers <karl AT turbobit.com>
11625 Fixed up SDCDB debugger somewhat. Updated debugger/README
11626 with lots of comments and notes.
11628 * device/examples/test2.c:
11629 Fix bug, "red" variable not being initialized(compiler complained).
11631 * device/examples/Makefile, examples/test3.c:
11632 Add Makefile in device/examples folder, compiles test3.c
11633 for use as a multiple module SDCDB test case.
11635 * sim/ucsim/cmd.src/cmdset.cc:
11636 Took out debug printfs in ucsim "next" command.
11638 * sim/ucsim/xa.src:
11639 Karl and Johan start ucsim XA support. Most dissassembly working,
11640 about 75% emulation done(plenty of work remaining).
11642 * sim/ucsim/z80.src:
11643 Add Z80 support to ucsim, add test-ucz80 regression test,
11644 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
11645 Notice z80 compiler fails on examples/test3.c/crc code.
11647 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>
11649 * src/mcs51/gen.c, src/mcs51/main.c, src/mcs51/ralloc.c:
11650 Added support for --parms-in-bank1
11652 * src/ds390/peeph.def:
11653 added a few more peephole optimzations
11655 * src/ds390/main.c:
11656 1) added __builtin_inp & __builtin_outp used to read in data of given length
11657 from a memory mapped port
11658 2) added __builtin_memcmp
11659 3) added __builtin_swapw swap bytes of a short
11661 * src/ds390/gen.c, src/ds390/gen.h, src/ds390/ralloc.c:
11662 1) handle multiple send & receives from register bank1
11663 2) ralloc can now allocate DPTR1 to some liveRanges
11665 * src/SDCCsymt.c, src/SDCCsymt.h:
11666 changes to handle multiple sends & receives
11668 * src/SDCCptropt.h:
11669 added some pointer arithmetic optimization
11671 * src/SDCCptropt.c:
