1370 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1372 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1373 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1375 One basic decision: e.g. src/clean.mk includes further files. In order
1376 to make this work there are two solutions:
1377 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1378 run configure on them. This way they can use
1379 'include $(srcdir)/port-clean.mk'
1380 - always include clean.mk by the Makefile at the same level. To avoid
1381 that `make clean` tries to include and build Makefile.dep the
1382 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1383 implemented, because now even `make uninstall` doesn't create
1384 Makefile.in. clean.mk could be eliminated by pasting it in
1387 * debugger/mcs51/Makefile.in: build own objects from library sources
1388 (SLIB, SDCC) in current directory
1390 * configure, configure.in: renamed --disable-device-lib-build in
1391 --disable-device-lib; added --enable-doc, the required tools are
1392 searched by configure; added result message; the toolchain for the
1393 belonging ports are now only built, if the port is enabled.
1395 * support/regression/*: all output is written in directory gen, because
1396 the fwk and ports directories don't livet in the build tree using vpath
1398 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1399 --disable-device-lib, added --enable-doc, added section VPATH
1401 * sim/ucsim/configure.in,
1402 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1403 z80 are enabled by default
1405 2006-04-24 Raphael Neider <rneider AT web.de>
1407 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1408 to config word, "pic14_"-prefixed some extern functions
1409 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1410 config word has been found
1411 * src/pic/device.h: added prototypes
1412 * src/pic/pcode.c: added "pic14_"-prefix where needed
1413 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
1415 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

1428 registers that have not been assigned proper liveranges,
1429 fixes #1469504 and #1474602,
1430 (pCodeRegOptimizeRegUsage): fixed typo in comment

1720 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1721 call to allocReg, not by manually allocating a new one,
1722 (pic16_assignRegisters): now before going through the register
1723 allocating functions mark all registers as free. This eliminates some
1724 side effects resulting from peephole parser done earlier in the backbone

1781 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
1783 * src/pic16/gen.c (genPcall): fixed bug #1443644
1784 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1785 which dumps before the function entry point a data byte which represents
1786 the number of the local variables used by the specified function, added
1787 'xinst' for initial support for Extended Instruction Support,
1788 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1789 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1790 port->fun_prefix anymore (may change later),
1791 (genFunction, genEndFunction): do not store/restore local registers for
1792 _main (this should take care the --main-return command line option in
1794 (genOr): removed some legacy pic-port instructions,
1795 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1796 performing operations with SFR's causes data to be written more than
1797 once to each SFR. Perhaps SFRs should be handled in special cases...
1798 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1800 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1801 into account for stack starting position,
1802 (struct OPTIONS pic16_optionsTable): added command line argument
1803 --extended or -y for Extended Instruction Support,
1804 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1805 (deassignLRs): *** perhaps the most important change, old 'for' code
1806 (commented out for reference), didn't account for some registers which
1807 were left marked 'not free' after a pointer operation. The change
1808 reduces register usage a lot in some cases

4081 * src/SDCCglobal.h (struct options),
4083 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
4084 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
4085 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
4086 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
4087 always available in leading double underscore form. The C99 support is
4088 mostly missing, but it's a start.
4089 * support/regression/tests/bug-227710.c: fixed nonconforming use of
4090 reserved identifier "__data".

4168 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
4170 * device/lib/printf_large.c: removed inline assembly for portability and
4171 readability. Use printf_fast if speed or size are more important.
4172 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4173 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4175 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4177 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4178 prevent compiler warning
4180 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4182 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4183 moved to level 0 and declared as static. Also they are explicit
4184 placed in access bank. This was necessery because some times they
4185 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4186 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4187 optimizations. Currently only compare to unsigned char is implemented,
4188 * src/pic16/gen.c: added fReturnIdx array,
4189 * (struct resolvedIfx) is moved to gen.h and made public,
4190 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4191 * (aopForSym): added an optimization to directly store in stack of
4192 the operand of a SEND iCode,
4193 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4194 but as registers instead (AOP_REG) using the fReturnIdx array,
4195 * (pic16_freeAsmop): remove the freed register from the
4196 _G.sregsAlloc field,
4197 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4198 a compare of 'WREG',
4199 * (pic16_popGetTempRegCond): changed function prototype, now
4200 function takes also a bitVector argument v which holds the current
4201 set of registers that are allocated for stack access by aopForSym,
4202 registers allocated in aopForSym for accessing stack symbols are not
4203 any more part of the functions usedRegs field,
4204 * (genCall): some times aopOp is called for a stack variable to be
4205 send, aopForSym might perform the push, if this is true make sure
4206 that genCall doesn't push the variable twice by testing _G.resDirect,
4207 * (genFunction): changed testing for unspecified interrupt number
4208 from 256 to INTNO_UNSPEC,
4209 * modified selection scheme of frame pointer generation. Previously
4210 if function did use local registers a frame pointer was generated,
4211 now a frame pointer is generated only if function has arguments
4212 (that need PLUSW2 register access), or has stack arguments, or the
4213 compiler is not instructed to omit the frame pointer,
4214 * (genEndFunction): before restoring local registers that were saved
4215 in the function preamble, also restore the registers that *might*
4216 have been allocated for stack access,
4217 * (genRet): removed some old comments,
4218 * (genCmp, the active (RN's) version): added a call to the
4219 pic16_genCmp_special function to perform the compare with a more
4220 robust and optimized way,
4221 * (genInline): a feature has been added in inline code generation,
4222 which allows a wildcard variable substitution when writing inline
4223 assembly. Code is incomplete and experimental therefore undocumented,
4224 * (genCast): changed order of aopOp for result and right to allow
4225 aopForSym to directly load the result if possible,
4226 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4227 perform an optimized compare on some selected special occasions,
4228 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4229 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4230 generate an IVT any more,
4231 * src/pic16/main.c (pic16_optionsTable): added command line option
4233 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4234 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4236 * src/pic16/NOTES: Raphael Neider added in list of active developers
4237 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4238 jumptable_end to prevent bug #,
4239 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4240 inCond and outCond fields,
4241 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4242 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4243 turn off register spilling,
4244 * (packRegsForOneUse): synced with other ports' versions although it
4245 is not used currently,
4246 * (pic16_packRegisters): added an optimization while reading
4247 structure bitfields, some registers may be saved (malloc code is
4248 decreased by 80 bytes)
4250 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4252 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4253 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4254 this can be optimized more?
4256 2005-03-10 Raphael Neider <rneider AT web.de>
4258 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4259 genNearPointerGet): (hopefully) fixed access to bitfields via
4260 pointers (p->bitN = x; and x = p->bitN; failed)
4262 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
4264 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

4303 2005-02-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4305 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
4306 to keep the correct label reference count when adding/removing references
4307 to labels. A peephole file using this is appended to patch #1144962.
4309 2005-02-14 Raphael Neider <rneider AT web.de>

4894 Adding support for replacing ljmps with sjmps in jumptables
4895 generated for switch statements. For now you need to set the
4896 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4897 Now 4 algorithms for mcs51 jumptable generation are used:
4898 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4899 addresses loaded pc-relative for up to 112 cases and stack-pushing
4900 target addresses loaded with offset from dptr for up to 256 cases.

4930 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4932 * added libc directory. The current version of LibC contains string
4933 functions, ctype functions and macros and some functions of the
4934 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4935 be extensively tested in the future. Standard disclaimer here.
4936 Library is not automatically build yet. But one can build it by
4937 invoking 'make' inside the libc directory.
4938 * added ADC library under libio. Preliminary version yet.

4947 * (genUminusFloat): fixed for pic16, ported code from mcs51,
4948 * (pic16_storeForReturn): optimized return of 0,
4949 * (genCmp): experimental code for new genCmp which uses PIC18's
4950 special compare&skip instructions. Initial tests fail some times
4951 with variables grater than 1 byte in size, so new code is disabled,
4952 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4954 * (genCast): began a fix to optimize the casting of a bit to another
4955 bit, now assigning a bitfield to another bitfield will fail, sorry,
4956 * src/pic16/main.c: disabled the use of lr-support feature,
4957 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

4960 bits with offset (case PO_GPR_BIT),
4961 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
4963 * (isBankInstruction): modified to return 0 for no banking instruction,
4964 and 1 for banking instruction,
4965 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4966 caused stop processing pCodes after a inline assembly block,
4967 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
4968 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
4969 registers when it shouldn't,
4970 * src/pic16/ralloc.c (allocReg): add preliminary support for
4971 supporting a limited set of temporary registers,
4973 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4975 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
4976 genDataPointerSet): ensure assignments always copy in MSB to LSB
4978 (loadRegFromAop): recognize CLRH optimization,
4979 (genFunction): optimize RECEIVE iCodes in reentrant functions
4981 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4983 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

7981 loaded with the linker search paths (-L arguments) and the libraries
7982 to be linked with the current source (-l arguments). Changes
7983 currently will affect only the pic16 port.
7984 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7985 include path the port specific paths and port specific libraries,
7986 * gplink command now contains the $3 argument,
7987 * src/pic16/device.h,

8004 Documenting changes from previous commits.
8005 * configure.in (version 1.56),
8006 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8007 when generating output files to configure the pic16 library,
8008 but now I've commented it out, since gputils aren't installed in the
8009 SF compile farm, so library won't compile
8011 * device/lib/Makefile.in (version 1.56): initially I've added in
8012 target 'all' the prerequestive 'model-pic16' so it compiled the
8013 pic16 library, but now I've commented it out for the same reasons
8015 * added targets 'model-pic16' and 'objects-pic16' to compile the
8017 * added target 'port-specific-objects-pic16' to handle the
8018 generated libraries and copy them into the build/ directory
8019 * added target 'clean-intermediate-pic16' to clean intermediate
8020 files into pic16 directory
8021 * in target 'installdirs' added line to create directory pic16 in

8025 added lines to copy all header files to installation path,
8026 * in target 'installdirs' added line create directory for pic16
8027 headers in the installation path

8332 added pic16_printExterns to print extern symbols,
8333 pic16glue: initializes stack/frame pointer in the beginning of
8334 the assembly output. Temporary hack, will be corrected later,
8335 because gplink yet does not support stack and SDCC does not
8336 yet support a type of crt0.o object to create the final binary.
8338 * Removed many lines that contain 8051 legacy code.
8339 * The code is finally placed under a 'code' directive.
8340 * Added port specific options.
8342 * _process_pragma: simplified since now we do not need *special*
8343 include file to define SFR registers. But a separate header
8344 will be needed. This will be developed later.
8345 * _pic16_parseOptions: added, parses port specific options:
8346 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8347 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8348 --preplace-udata-with=
8350 * _pic16_setDefaultOptions: modified to initialize section names,
8351 but hack is temporarly out of order since it needs improvement.
8352 * _pic16_genAssemblerPreamble: configuration words are emitted by
8353 their address instead of their name. This part is incomplete and
8354 supports only the 18Fxx2 devices. Other devices will emit an error
8355 during assembly since they do not contain the same set of config
8357 * _pic16_genIVT: is modified,
8359 * pcode.c: added definitions for some hardware registers that are needed
8361 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8362 All PCI entries are updated. Now LFSR is supported.
8363 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8364 * added pic16_newpCodeOpLit2 to support instructions with
8365 two literal arguments
8366 * pic16_pCode2str: corrected code that emits assembler instructions
8367 with two literal operands and those that have an access bit modifier
8368 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8369 this fixes a bug which caused some labels to be lost, when an
8370 assembler directive was added, i.e. banksel,
8371 * pic16_FixRegisterBanking: improved logic that causes the insertion
8373 * InlineFunction: functions that are called once, are not any more
8374 inlined. This can be a port option in the future,
8376 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8378 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8379 hold the corresponding uninitialized symbols,
8380 * pic16_allocProcessorRegister: registers have explicit marked the
8382 * pic16_allocInternalRegister: registers are explicit marked as
8384 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8385 processing list, so bit registers were lost,
8388 * ralloc.h: added field 'accessBank' and original symbol operand
8389 in register definition,
8390 * removed the field isMapped from register definition,
8392 ** Several functions have been removed from various sources:
8393 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8394 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8395 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8396 pic16_assignRelocatableRegisters
8398 ** others have been introduced:
8399 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8400 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8402 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8404 * support/scripts/inc2h.pl: changed definition of BIT_AT
8405 to emit 'sbit at' instead of 'bit at'. This was a request.
8407 PIC16 port related preliminary changes:
8408 * gen.c: prefixed function popRegFromString with
8409 pic16_ and all references to it corrected
8410 * pcode.c: all pic16_pc_* hardware registers prefixed
8411 with underscore (_),
8412 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8413 * ralloc.c: newReg(): when register is REG_SFR then
8414 set address to rIdx,
8415 pic16_allocProcessorRegister(): marks register wasUsed=0
8416 pic16_writeUsedRegs(): added a call to assign processor
8417 registers via pic16_assignFixedRegisters
8419 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8421 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8422 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8423 variables in unused register banks. Also the SSEG is placed
8424 wherever there is enough space for it, and IDATA can be anywhere
8425 in internal RAM. For now compile using -Wl-Y[stack_size].
8426 The mem file is different for this option as well, since it
8427 makes no sense of talking about DSEG lenght.
8429 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8431 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8432 in certain cases, e.g. when ROM assignment, patch provided
8433 from Albert den Haan.

8676 * src/SDCCast.c (decorateType): disabled a transformation I added in
8677 revision 1.188 (access to fields of a structure at an absolute address);
8678 it breaks with bitfields, extern declarations, and gcse analysis.
8679 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
8680 could be assigned through a pointer, so don't complain.
8681 * src/SDCCast.c (astErrors),
8683 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

8785 * src/mcs51/main.c: started fixing bug #737001 (SDCC not clearing
8786 uninitialized variables) for the mcs51. Set environment variable
8787 SDCC_GENRAMCLEAR to test.
8788 xdata initialization slightly shorter
8790 2003-11-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9437 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
9438 fetching of the pointer
9439 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
9440 copied from genNearPointerSet()
9441 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
9442 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

9458 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9459 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9460 type for bits was changed. It resulted in bit variables becoming
9461 global, which is not permitted in PIC 14 assembly output.
9463 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9465 * doc/sdccman.lyx: various additions and updates. Rearranged sections

9478 A few small changes that speed up the peephole optimizer.
9482 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9484 Try to make the peephole optimizer smarter by maintaining
9485 an association between the assembly source code and the
9486 iCodes that originated them. Put this information to use
9487 with a new peephole rule condition "notVolatile" so that
9488 the rules can be aggressive yet still safe.
9493 * src/mcs51/peeph.def
9495 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9499 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9500 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9501 if the left or right operand symbols have the accuse flag set.
9503 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9505 Changed the type of the result of the ! (NOT) operator to char;
9506 previously it returned the same type as the source. This allows
9507 us to eliminate all the genFloatNot functions (all of its target
9508 implementations were very buggy) since !float can use the same

9520 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9521 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9522 during interrupts. Ensure WSAVE is located at a shared bank address.
9523 2. Fixed page selection in some places
9524 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9525 the registers name strings.
9526 4. Fixed "signed / unsigned compare" compiler warnings.
9527 5. The PIC port manages its own allocation of the general purpose
9528 registers, but makes no attempt to reuse them. As a result when
9529 compiling it soon runs out of general purpose registers. Some
9530 additional code was added to the files pcode.c and device.c to walk
9531 through the function call tree and rename the registers so that they
9541 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9542 genPlus() & genMinus() when the result is the same as left or right

9548 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9550 Made bitfield a distinct type from bit so that bitfields
9551 convert as per ANSI C and bits retain their traditional
9552 boolean style behaviour. Implemented bitfield support in
9560 * src/ds390/gen.c: bit v bitfield split
9561 * src/z80/gen.c: New support for bitfields
9562 * support/regression/tests/bitfields.c: reenabled z80,
9565 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9567 Rules 246.x, 247.x relate to bitfields, the others speed up
9568 access to xdata mapped I/O devices.
9570 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9572 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9574 Cleaned up genPackBits and genUnpackBits and added two helper
9575 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9576 for literal assignments in genPackBits (thanks to Frieder for
9582 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9584 Fixed bug #748310 (pointer to function type mishandled when the
9585 function name is omitted). Also fixed a SIGSEGV when a function
9586 attribute (reentrant, etc) is used on a non-function or on a
9587 function but misplaced before the parameter list.
9589 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9591 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
9592 * support/Util/SDCCerr.h,
9593 * support/Util/SDCCerr.c: Added func attr misuse error msg

9614 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9616 Made the constant following the "interrupt" keyword optional. If
9617 omitted, the function will not automatically be given an entry
9618 in the interrupt vector table (similar to #pragma NOIV, but
9619 less syntacticly kludgy). The interrupt number is also now
9620 range checked. Also fixed a bug in the high order bit example

9634 * src/SDCCicode.c (operandOperation): rewritten some ops
9635 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
9636 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9638 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9639 be re-activated by defining REDUCE_LITERALS)
9640 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
9641 unsigned, but are signed by default
9642 * src/SDCCval.c (constVal): rearranged
9643 * src/SDCCval.c (valMod): preliminary fix
9644 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9686 constants are unsigned; added recognition of "u" flag for unsigned
9687 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
9688 * src/SDCCval.c (valDiv, valMod): fixed signdness

10150 added if/endif conditional macros to remove options help
10151 messages from optionsTable when a port is not configured, added
10152 support for the PIc16 port in the ports table, when executing
10153 the compiler with no port specified on command line, a default
10154 port is selected with the new macro DEFAULT_PORT which is
10155 defined in port.h, in setDefaultOptions() linkOptions is removed
10156 from initialization assignment, since now it is a set,
10157 parseCmdLine uses setParseWithComma for linkOptions, in
10158 linkEdit() linkOptions are accessed with new function indexSet()
10159 which returns the i'th item of a set variable. See SDCCset.c, in
10160 linkEdit() when calling buildCmdLine(), added linkOptions as
10161 last argument. Now users can pass arguments to gplink via the
10162 -Wl option, main() uses pic16glue() to glue up pic16 programs

10176 gpasm complaining and test the linkage with gplink, _linkCmd and
10177 _asmCmd changed to be more gplink and gpasm friendly
10178 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10179 produced an error when parsed, peep rule 12 is added to utilize
10180 movff, but it is commented out since the pCode does not support
10181 yet a command with 2 address arguments
10183 2003-05-18 <johan AT balder>
10185 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

11201 * src/mcs51/gen.c (genPlus): replaced "mov b,acc" by "mov b,a" Fiorenzo D. Ramaglia <fd.ramaglia AT tin.it>
11203 2003-01-07 <johan AT balder>
11205 * src/SDCCast.c (decorateType): fixed bug #600035
11207 2003-01-07 Bernhard Held <bernhard AT bernhardheld.de>
11208 * as/mcs51/lkmem.c: added several l-modifiers to printf to remove warnings
11209 * as/mcs51/lkaomf51.c: #include <ctype.h> to remove warnings
11210 * src/pic/main.c (_hasNativeMulFor): outcommented unused variables to remove warnings
11211 * src/pic/pcode.c: outcommented unused variable to remove warnings
11212 * src/pic/ralloc.c: outcommented unused variable to remove warnings
11214 2003-01-06 <karl AT turbobit.com>
11215 * sim/ucsim/cmd.src/command.cc: fixed so "break xram r 0x7654" works again in
11218 2003-01-06 <johan AT balder>
11220 * src/SDCCicode.c: fixed array add
11222 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
11223 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
11224 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
11226 2003-01-04 <johan AT balder>
11228 * src/SDCCval.c (getNelements): fixed the initialized array of structures
11230 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11231 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
11233 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
11234 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
11235 * support/regression/tests/bug-524697.c: fit mem usage into 8032
11237 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
11238 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
11240 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
11241 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
11243 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
11244 * src/mcs51/main.c: removed {bindir}{sep} from aslink
11246 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11248 * in /sdcc/as/mcs51/ changed these files in order to create an
11249 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11250 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11251 following files to include the previous two files: aslink.dsp,
11252 Makefile.aslink, Makefile.bcc, and Makefile.in.
11254 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11255 .adb instead of .cdb
11257 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11259 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11260 value from option --iram-size.
11262 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11264 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11267 2002-09-18 <wiml AT hhhh.org>
11269 * SDCClrange.h: exposed setFromRange() and setToRange()
11270 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11271 packRegsForAccUse() (bug 542397)
11272 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11273 multiple times and emitting the fetch operations more than once
11274 added aopGetUsesAcc() function to allow binary operators to
11275 fetch their operands in the correct order; made genMinus() emit
11276 compact code for X = LITERAL - Y
11278 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11279 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11280 sprintf() in line 1267.
11282 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11283 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11286 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11287 Changes to aslink (All the changes are marked with 'JCF'):
11289 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11292 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11293 area BSEG. Also moves, if possible, the DATA area down into the internal
11294 ram so more space is available.
11296 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11299 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11300 not bytes. Function summary() which creates a memory usage summary
11301 file with extension .mem. Reports of overlaping stack and small stack
11302 size. If the space for the stack is less than 16 bytes aslink trows a
11305 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11306 the 8051. Option 'y' for memory summary output file.
11308 Changes to sdcc (All the changes are marked with 'JCF'):
11310 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11312 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11313 overlaying area for it (uses RegBankUsed[4]).
11315 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11316 bank zero as used by default. By default aslink locates the stack
11317 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11318 the creation of the .mem file. Delegates the allocation of data area
11319 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11320 the begining of the stack area to aslink.
11322 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11323 glue() in SDCCglue.c creates an area for it.
11325 2002-09-03 Borut Razem <borut.razem AT siol.net>
11326 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11327 sdcc/src/pic/glue.c:
11328 introduced atexit() handler for teporay files removal in case of
11329 errors, assertions, ...
11331 2002-08-29 Borut Razem <borut.razem AT siol.net>
11332 * sdcc/support/cpp2/auto-host_vc_in.h:
11333 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11334 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11335 Maybe there is a similar problem with BORLANDC? It should be checked!
11337 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11338 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11339 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11340 was not executed, and the compiler (cl) launched a warning:
11341 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11343 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11344 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11346 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11347 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11349 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11350 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11351 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11352 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11353 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11354 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11355 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11356 - added Release configuration in VS projects
11357 - review of compiler an linker options
11358 - VC .exe files are generated in bin_vc directory, not to interfere
11359 with binaries generated from other projects (cygwin, mingw, bcc ...)
11361 * sdcc/src/yacc.dsp: added
11363 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11364 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11365 and insert the version number definitions from .version
11367 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11369 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11370 added - genarate auto-host.h using auto-host_vc_in.h as template
11373 removed from CVS, generated automatically
11375 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11376 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11378 2002-08-11 Borut Razem <borut.razem AT siol.net>
11379 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11381 2002-08-10 Borut Razem <borut.razem AT siol.net>
11382 * src/SDCCmain.c (main):
11383 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11384 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11385 The consequence was that some temporary files were not removed.
11388 unification of code in functions tempfilename() and tempfile():
11389 function tempnam() is defined in Visual Studio 6.0 and .NET
11391 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11393 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11394 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11395 - removed compiler command line option /WX: Treats all warnings as errors
11396 - update a list of source files, included into the project
11398 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11399 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11400 changed project type to Generic Project so that can be correcly converted to VS.NET project
11402 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11404 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11406 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11408 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11409 added return 0 statements after assert() to make compiler happy
11411 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11412 added newline in the def file to keep MSC compiler satisfied
11414 * sdcc/src/z80/gen.c:
11415 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11416 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11417 - solved MSC error in function aopDump()
11419 * sdcc_vc.h: define PREFIX as "\\sdcc"
11421 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
11422 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

11425 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
11426 - Rewrote the register banking algorithm.
11427 - Added pCode live-range analysis to registers (for now, only non-used and
11428 singly-used registers optimized away)
11430 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
11432 * 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.

11455 * src/z80/main.c: Added force callee saves for jaune.
11457 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
11459 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
11461 2002-03-28 Johan Knol <johan AT balder>
11463 * src/SDCCval.c: fixed bug #532436
11465 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11467 Added "char *Processor" field to the port structure.
11470 Added -p option. Allows port dependent processor to be specified.
11473 Initialized the new field char *Processor field to NULL in all ports
11476 Compiler generated registers for interrupt context saving
11477 were not getting allocated.
11479 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
11482 Fixed left shift. Will promote the left side of a left shift
11483 if a) left shifting more than size of operand or b) when assigned
11484 to something size > size of left side
11486 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11488 tons of changes. Register allocation has been
11489 rewritten. Added customization for the various PICs. Flow
11490 analysis is restructured. ...
11492 * src/pic/device.h:
11495 * src/pic/device.c:
11496 Added. device.c is a PIC port hack to accomodate variations
11499 2002-03-13 Michael Hope <michaelh AT vroom>
11501 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
11503 2002-03-04 johanknol <johanknol AT manik>
11505 * /src/SDCCval.c: fixed
11507 const unsigned char arr[][2] = { { 0, 1 } };
11508 t18.c:1: error: Initializer element is not constant

11594 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
11596 * sdcc/src/SDCCloop.c:
11597 Previous fix was not good. basic blocks that have "break" or "return" are
11598 not really partof a loop , but live ranges used in these blocks should
11599 be live thru the entire loop, so set partOfLoop but don't add them to
11602 2002-02-21 <johan AT FRIJA>
11604 * src/SDCCcse.c: fixed bug #514308
11606 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
11609 Fixed BUG #519583. If a conditional block ended in a return/break
11610 statement inside a loop, it was not being considered part of the loop.
11612 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
11614 2002-02-10 Karl Bongers <karl AT turbobit.com>

11618 with lots of comments and notes.
11620 * device/examples/test2.c:
11621 Fix bug, "red" variable not being initialized(compiler complained).
11623 * device/examples/Makefile, examples/test3.c:
11624 Add Makefile in device/examples folder, compiles test3.c
11625 for use as a multiple module SDCDB test case.
11627 * sim/ucsim/cmd.src/cmdset.cc:
11628 Took out debug printfs in ucsim "next" command.
11630 * sim/ucsim/xa.src:
11631 Karl and Johan start ucsim XA support. Most dissassembly working,
11632 about 75% emulation done(plenty of work remaining).
11634 * sim/ucsim/z80.src:
11635 Add Z80 support to ucsim, add test-ucz80 regression test,
11636 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
11637 Notice z80 compiler fails on examples/test3.c/crc code.
11639 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>
11641 * src/mcs51/gen.c, src/mcs51/main.c, src/mcs51/ralloc.c:
11642 Added support for --parms-in-bank1
11644 * src/ds390/peeph.def:
11645 added a few more peephole optimzations
11647 * src/ds390/main.c:
11648 1) added __builtin_inp & __builtin_outp used to read in data of given length
11649 from a memory mapped port
11650 2) added __builtin_memcmp
11651 3) added __builtin_swapw swap bytes of a short
11653 * src/ds390/gen.c, src/ds390/gen.h, src/ds390/ralloc.c:
11654 1) handle multiple send & receives from register bank1
11655 2) ralloc can now allocate DPTR1 to some liveRanges
11657 * src/SDCCsymt.c, src/SDCCsymt.h:
11658 changes to handle multiple sends & receives
11660 * src/SDCCptropt.h:
11661 added some pointer arithmetic optimization
11663 * src/SDCCptropt.c:
11664 added some pointer arithmetic optimizations but not stable yet so not
11665 called from anywhere (will get this working shortly)
11667 * src/SDCCopt.c: fixed for multiple sends & receives
