1374 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1376 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1377 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1379 One basic decision: e.g. src/clean.mk includes further files. In order
1380 to make this work there are two solutions:
1381 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1382 run configure on them. This way they can use
1383 'include $(srcdir)/port-clean.mk'
1384 - always include clean.mk by the Makefile at the same level. To avoid
1385 that `make clean` tries to include and build Makefile.dep the
1386 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1387 implemented, because now even `make uninstall` doesn't create
1388 Makefile.in. clean.mk could be eliminated by pasting it in
1391 * debugger/mcs51/Makefile.in: build own objects from library sources
1392 (SLIB, SDCC) in current directory
1394 * configure, configure.in: renamed --disable-device-lib-build in
1395 --disable-device-lib; added --enable-doc, the required tools are
1396 searched by configure; added result message; the toolchain for the
1397 belonging ports are now only built, if the port is enabled.
1399 * support/regression/*: all output is written in directory gen, because
1400 the fwk and ports directories don't livet in the build tree using vpath
1402 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1403 --disable-device-lib, added --enable-doc, added section VPATH
1405 * sim/ucsim/configure.in,
1406 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1407 z80 are enabled by default
1409 2006-04-24 Raphael Neider <rneider AT web.de>
1411 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1412 to config word, "pic14_"-prefixed some extern functions
1413 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1414 config word has been found
1415 * src/pic/device.h: added prototypes

1724 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1725 call to allocReg, not by manually allocating a new one,
1726 (pic16_assignRegisters): now before going through the register
1727 allocating functions mark all registers as free. This eliminates some
1728 side effects resulting from peephole parser done earlier in the backbone

1780 2006-03-06 Borut Razem <borut.razem AT siol.net>
1782 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
1783 made the linker quiet
1785 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
1787 * src/pic16/gen.c (genPcall): fixed bug #1443644
1788 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1789 which dumps before the function entry point a data byte which represents
1790 the number of the local variables used by the specified function, added
1791 'xinst' for initial support for Extended Instruction Support,
1792 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1793 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1794 port->fun_prefix anymore (may change later),
1795 (genFunction, genEndFunction): do not store/restore local registers for
1796 _main (this should take care the --main-return command line option in
1798 (genOr): removed some legacy pic-port instructions,
1799 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1800 performing operations with SFR's causes data to be written more than
1801 once to each SFR. Perhaps SFRs should be handled in special cases...
1802 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1804 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1805 into account for stack starting position,
1806 (struct OPTIONS pic16_optionsTable): added command line argument
1807 --extended or -y for Extended Instruction Support,
1808 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1809 (deassignLRs): *** perhaps the most important change, old 'for' code
1810 (commented out for reference), didn't account for some registers which
1811 were left marked 'not free' after a pointer operation. The change
1812 reduces register usage a lot in some cases

4085 * src/SDCCglobal.h (struct options),
4087 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
4088 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
4089 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
4090 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
4091 always available in leading double underscore form. The C99 support is
4092 mostly missing, but it's a start.

4172 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
4174 * device/lib/printf_large.c: removed inline assembly for portability and
4175 readability. Use printf_fast if speed or size are more important.
4176 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4177 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4179 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4181 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4182 prevent compiler warning
4184 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4186 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4187 moved to level 0 and declared as static. Also they are explicit
4188 placed in access bank. This was necessery because some times they
4189 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4190 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4191 optimizations. Currently only compare to unsigned char is implemented,
4192 * src/pic16/gen.c: added fReturnIdx array,
4193 * (struct resolvedIfx) is moved to gen.h and made public,
4194 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4195 * (aopForSym): added an optimization to directly store in stack of
4196 the operand of a SEND iCode,
4197 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4198 but as registers instead (AOP_REG) using the fReturnIdx array,
4199 * (pic16_freeAsmop): remove the freed register from the
4200 _G.sregsAlloc field,
4201 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4202 a compare of 'WREG',
4203 * (pic16_popGetTempRegCond): changed function prototype, now
4204 function takes also a bitVector argument v which holds the current
4205 set of registers that are allocated for stack access by aopForSym,
4206 registers allocated in aopForSym for accessing stack symbols are not
4207 any more part of the functions usedRegs field,
4208 * (genCall): some times aopOp is called for a stack variable to be
4209 send, aopForSym might perform the push, if this is true make sure
4210 that genCall doesn't push the variable twice by testing _G.resDirect,
4211 * (genFunction): changed testing for unspecified interrupt number
4212 from 256 to INTNO_UNSPEC,
4213 * modified selection scheme of frame pointer generation. Previously
4214 if function did use local registers a frame pointer was generated,
4215 now a frame pointer is generated only if function has arguments
4216 (that need PLUSW2 register access), or has stack arguments, or the
4217 compiler is not instructed to omit the frame pointer,
4218 * (genEndFunction): before restoring local registers that were saved
4219 in the function preamble, also restore the registers that *might*
4220 have been allocated for stack access,
4221 * (genRet): removed some old comments,
4222 * (genCmp, the active (RN's) version): added a call to the
4223 pic16_genCmp_special function to perform the compare with a more
4224 robust and optimized way,
4225 * (genInline): a feature has been added in inline code generation,
4226 which allows a wildcard variable substitution when writing inline
4227 assembly. Code is incomplete and experimental therefore undocumented,
4228 * (genCast): changed order of aopOp for result and right to allow
4229 aopForSym to directly load the result if possible,
4230 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4231 perform an optimized compare on some selected special occasions,
4232 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4233 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4234 generate an IVT any more,
4235 * src/pic16/main.c (pic16_optionsTable): added command line option
4237 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4238 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4240 * src/pic16/NOTES: Raphael Neider added in list of active developers
4241 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4242 jumptable_end to prevent bug #,
4243 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4244 inCond and outCond fields,
4245 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4246 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4247 turn off register spilling,
4248 * (packRegsForOneUse): synced with other ports' versions although it
4249 is not used currently,
4250 * (pic16_packRegisters): added an optimization while reading
4251 structure bitfields, some registers may be saved (malloc code is
4252 decreased by 80 bytes)
4254 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4256 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4257 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4258 this can be optimized more?
4260 2005-03-10 Raphael Neider <rneider AT web.de>
4262 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4263 genNearPointerGet): (hopefully) fixed access to bitfields via
4264 pointers (p->bitN = x; and x = p->bitN; failed)
4266 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
4268 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

4307 2005-02-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4309 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
4310 to keep the correct label reference count when adding/removing references

4898 Adding support for replacing ljmps with sjmps in jumptables
4899 generated for switch statements. For now you need to set the
4900 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4901 Now 4 algorithms for mcs51 jumptable generation are used:
4902 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4903 addresses loaded pc-relative for up to 112 cases and stack-pushing
4904 target addresses loaded with offset from dptr for up to 256 cases.

4934 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4936 * added libc directory. The current version of LibC contains string
4937 functions, ctype functions and macros and some functions of the
4938 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4939 be extensively tested in the future. Standard disclaimer here.
4940 Library is not automatically build yet. But one can build it by
4941 invoking 'make' inside the libc directory.

4952 * (pic16_storeForReturn): optimized return of 0,
4953 * (genCmp): experimental code for new genCmp which uses PIC18's
4954 special compare&skip instructions. Initial tests fail some times
4955 with variables grater than 1 byte in size, so new code is disabled,
4956 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4958 * (genCast): began a fix to optimize the casting of a bit to another
4959 bit, now assigning a bitfield to another bitfield will fail, sorry,
4960 * src/pic16/main.c: disabled the use of lr-support feature,
4961 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

4968 and 1 for banking instruction,
4969 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4970 caused stop processing pCodes after a inline assembly block,
4971 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
4972 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
4973 registers when it shouldn't,
4974 * src/pic16/ralloc.c (allocReg): add preliminary support for
4975 supporting a limited set of temporary registers,
4977 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4979 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,

4982 (loadRegFromAop): recognize CLRH optimization,
4983 (genFunction): optimize RECEIVE iCodes in reentrant functions
4985 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4987 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

7896 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
7898 * src/SDCCast.c: added an additional type flow in decorateType() of
7899 opposite direction, see feature request #860006; it's enabled at runtime
7900 by setting the environment variable SDCC_NEWTYPEFLOW
7901 * src/SDCCast.h: changed prototype of decorateType()
7902 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()

7982 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
7984 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
7985 loaded with the linker search paths (-L arguments) and the libraries
7986 to be linked with the current source (-l arguments). Changes
7987 currently will affect only the pic16 port.
7988 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7989 include path the port specific paths and port specific libraries,
7990 * gplink command now contains the $3 argument,
7991 * src/pic16/device.h,
7992 * src/pic16/device.c,: structure PIC_device is made public and
7993 renamed to PIC16_device, the same for variable Pics which is renamed

8008 Documenting changes from previous commits.
8009 * configure.in (version 1.56),
8010 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8011 when generating output files to configure the pic16 library,
8012 but now I've commented it out, since gputils aren't installed in the
8013 SF compile farm, so library won't compile
8015 * device/lib/Makefile.in (version 1.56): initially I've added in
8016 target 'all' the prerequestive 'model-pic16' so it compiled the
8017 pic16 library, but now I've commented it out for the same reasons
8019 * added targets 'model-pic16' and 'objects-pic16' to compile the
8021 * added target 'port-specific-objects-pic16' to handle the
8022 generated libraries and copy them into the build/ directory
8023 * added target 'clean-intermediate-pic16' to clean intermediate
8024 files into pic16 directory
8025 * in target 'installdirs' added line to create directory pic16 in

8029 added lines to copy all header files to installation path,
8030 * in target 'installdirs' added line create directory for pic16
8031 headers in the installation path

8328 * added files genutils.c and genutils.h which contain gen*
8329 debugged and optimised functions extracted from gen.c
8331 * glue.c: added variable 'externs' which holds extern symbols,
8332 pic16emitRegularMap: is modified to properly handle relocatable
8333 symbols under the new scheme,
8334 pic16createInterruptVect: is modified
8335 pic16printPublics: is modified to emit 'global' assembler directives,
8336 added pic16_printExterns to print extern symbols,
8337 pic16glue: initializes stack/frame pointer in the beginning of
8338 the assembly output. Temporary hack, will be corrected later,
8339 because gplink yet does not support stack and SDCC does not
8340 yet support a type of crt0.o object to create the final binary.
8342 * Removed many lines that contain 8051 legacy code.
8343 * The code is finally placed under a 'code' directive.
8344 * Added port specific options.
8346 * _process_pragma: simplified since now we do not need *special*
8347 include file to define SFR registers. But a separate header
8348 will be needed. This will be developed later.
8349 * _pic16_parseOptions: added, parses port specific options:
8350 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8351 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8352 --preplace-udata-with=
8354 * _pic16_setDefaultOptions: modified to initialize section names,
8355 but hack is temporarly out of order since it needs improvement.
8356 * _pic16_genAssemblerPreamble: configuration words are emitted by
8357 their address instead of their name. This part is incomplete and
8358 supports only the 18Fxx2 devices. Other devices will emit an error
8359 during assembly since they do not contain the same set of config
8361 * _pic16_genIVT: is modified,
8363 * pcode.c: added definitions for some hardware registers that are needed
8365 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8366 All PCI entries are updated. Now LFSR is supported.
8367 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8368 * added pic16_newpCodeOpLit2 to support instructions with
8369 two literal arguments
8370 * pic16_pCode2str: corrected code that emits assembler instructions
8371 with two literal operands and those that have an access bit modifier
8372 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8373 this fixes a bug which caused some labels to be lost, when an
8374 assembler directive was added, i.e. banksel,
8375 * pic16_FixRegisterBanking: improved logic that causes the insertion
8377 * InlineFunction: functions that are called once, are not any more
8378 inlined. This can be a port option in the future,
8380 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8382 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8383 hold the corresponding uninitialized symbols,
8384 * pic16_allocProcessorRegister: registers have explicit marked the
8386 * pic16_allocInternalRegister: registers are explicit marked as
8388 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8389 processing list, so bit registers were lost,
8392 * ralloc.h: added field 'accessBank' and original symbol operand
8393 in register definition,
8394 * removed the field isMapped from register definition,
8396 ** Several functions have been removed from various sources:
8397 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8398 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8399 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8400 pic16_assignRelocatableRegisters
8402 ** others have been introduced:
8403 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8404 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8406 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8408 * support/scripts/inc2h.pl: changed definition of BIT_AT
8409 to emit 'sbit at' instead of 'bit at'. This was a request.
8411 PIC16 port related preliminary changes:
8412 * gen.c: prefixed function popRegFromString with
8413 pic16_ and all references to it corrected
8414 * pcode.c: all pic16_pc_* hardware registers prefixed
8415 with underscore (_),
8416 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8417 * ralloc.c: newReg(): when register is REG_SFR then
8418 set address to rIdx,
8419 pic16_allocProcessorRegister(): marks register wasUsed=0
8420 pic16_writeUsedRegs(): added a call to assign processor
8421 registers via pic16_assignFixedRegisters
8423 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8425 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8426 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8427 variables in unused register banks. Also the SSEG is placed
8428 wherever there is enough space for it, and IDATA can be anywhere
8429 in internal RAM. For now compile using -Wl-Y[stack_size].
8430 The mem file is different for this option as well, since it
8431 makes no sense of talking about DSEG lenght.
8433 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8435 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8436 in certain cases, e.g. when ROM assignment, patch provided
8437 from Albert den Haan.
8439 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8582 * src/mcs51/peephole.def,
8583 * src/ds390/peephole.def: using the atomic test and clear instruction jbc

8595 multiply defined with mismatching "at" address.
8597 2003-12-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8678 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8680 * src/SDCCast.c (decorateType): disabled a transformation I added in
8681 revision 1.188 (access to fields of a structure at an absolute address);
8682 it breaks with bitfields, extern declarations, and gcse analysis.
8683 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
8684 could be assigned through a pointer, so don't complain.
8685 * src/SDCCast.c (astErrors),
8687 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

8787 2003-11-13 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8789 * src/mcs51/main.c: started fixing bug #737001 (SDCC not clearing
8790 uninitialized variables) for the mcs51. Set environment variable

9441 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
9442 fetching of the pointer
9443 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
9444 copied from genNearPointerSet()
9445 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
9446 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
9447 If they pop r0/r1 they must be called in the opposite order than aopOp().

9460 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
9462 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9463 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9464 type for bits was changed. It resulted in bit variables becoming
9465 global, which is not permitted in PIC 14 assembly output.
9467 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9469 * doc/sdccman.lyx: various additions and updates. Rearranged sections

9482 A few small changes that speed up the peephole optimizer.
9486 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9488 Try to make the peephole optimizer smarter by maintaining
9489 an association between the assembly source code and the
9490 iCodes that originated them. Put this information to use
9491 with a new peephole rule condition "notVolatile" so that
9492 the rules can be aggressive yet still safe.
9497 * src/mcs51/peeph.def
9499 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9503 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9504 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9505 if the left or right operand symbols have the accuse flag set.
9507 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9509 Changed the type of the result of the ! (NOT) operator to char;
9510 previously it returned the same type as the source. This allows
9511 us to eliminate all the genFloatNot functions (all of its target
9512 implementations were very buggy) since !float can use the same
9515 * src/SDCCicode.c (ast2iCode): ! returns char

9524 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9525 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9526 during interrupts. Ensure WSAVE is located at a shared bank address.
9527 2. Fixed page selection in some places
9528 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9529 the registers name strings.
9530 4. Fixed "signed / unsigned compare" compiler warnings.
9531 5. The PIC port manages its own allocation of the general purpose
9532 registers, but makes no attempt to reuse them. As a result when
9533 compiling it soon runs out of general purpose registers. Some
9534 additional code was added to the files pcode.c and device.c to walk
9535 through the function call tree and rename the registers so that they
9545 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9546 genPlus() & genMinus() when the result is the same as left or right

9552 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9554 Made bitfield a distinct type from bit so that bitfields
9555 convert as per ANSI C and bits retain their traditional
9556 boolean style behaviour. Implemented bitfield support in
9564 * src/ds390/gen.c: bit v bitfield split
9565 * src/z80/gen.c: New support for bitfields
9566 * support/regression/tests/bitfields.c: reenabled z80,
9569 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9571 Rules 246.x, 247.x relate to bitfields, the others speed up
9572 access to xdata mapped I/O devices.
9574 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9576 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9578 Cleaned up genPackBits and genUnpackBits and added two helper
9579 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9580 for literal assignments in genPackBits (thanks to Frieder for
9586 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9588 Fixed bug #748310 (pointer to function type mishandled when the
9589 function name is omitted). Also fixed a SIGSEGV when a function
9590 attribute (reentrant, etc) is used on a non-function or on a
9591 function but misplaced before the parameter list.
9593 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9595 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
9596 * support/Util/SDCCerr.h,
9597 * support/Util/SDCCerr.c: Added func attr misuse error msg

9618 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9620 Made the constant following the "interrupt" keyword optional. If
9621 omitted, the function will not automatically be given an entry
9622 in the interrupt vector table (similar to #pragma NOIV, but
9623 less syntacticly kludgy). The interrupt number is also now
9624 range checked. Also fixed a bug in the high order bit example

9638 * src/SDCCicode.c (operandOperation): rewritten some ops
9639 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
9640 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9642 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9643 be re-activated by defining REDUCE_LITERALS)
9644 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
9645 unsigned, but are signed by default
9646 * src/SDCCval.c (constVal): rearranged
9647 * src/SDCCval.c (valMod): preliminary fix
9648 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9690 constants are unsigned; added recognition of "u" flag for unsigned
9691 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
9692 * src/SDCCval.c (valDiv, valMod): fixed signdness
9693 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
9694 signedness of modulo, left and right shift

10154 added if/endif conditional macros to remove options help
10155 messages from optionsTable when a port is not configured, added
10156 support for the PIc16 port in the ports table, when executing
10157 the compiler with no port specified on command line, a default
10158 port is selected with the new macro DEFAULT_PORT which is
10159 defined in port.h, in setDefaultOptions() linkOptions is removed
10160 from initialization assignment, since now it is a set,
10161 parseCmdLine uses setParseWithComma for linkOptions, in
10162 linkEdit() linkOptions are accessed with new function indexSet()
10163 which returns the i'th item of a set variable. See SDCCset.c, in
10164 linkEdit() when calling buildCmdLine(), added linkOptions as
10165 last argument. Now users can pass arguments to gplink via the
10166 -Wl option, main() uses pic16glue() to glue up pic16 programs

10180 gpasm complaining and test the linkage with gplink, _linkCmd and
10181 _asmCmd changed to be more gplink and gpasm friendly
10182 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10183 produced an error when parsed, peep rule 12 is added to utilize
10184 movff, but it is commented out since the pCode does not support
10185 yet a command with 2 address arguments
10187 2003-05-18 <johan AT balder>
10189 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

11207 2003-01-07 <johan AT balder>
11209 * src/SDCCast.c (decorateType): fixed bug #600035
11211 2003-01-07 Bernhard Held <bernhard AT bernhardheld.de>
11212 * as/mcs51/lkmem.c: added several l-modifiers to printf to remove warnings
11213 * as/mcs51/lkaomf51.c: #include <ctype.h> to remove warnings
11214 * src/pic/main.c (_hasNativeMulFor): outcommented unused variables to remove warnings
11215 * src/pic/pcode.c: outcommented unused variable to remove warnings

11222 2003-01-06 <johan AT balder>
11224 * src/SDCCicode.c: fixed array add
11226 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
11227 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
11228 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
11230 2003-01-04 <johan AT balder>
11232 * src/SDCCval.c (getNelements): fixed the initialized array of structures
11234 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11235 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
11237 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
11238 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
11239 * support/regression/tests/bug-524697.c: fit mem usage into 8032
11241 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
11242 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
11244 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
11245 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
11247 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
11248 * src/mcs51/main.c: removed {bindir}{sep} from aslink
11250 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11252 * in /sdcc/as/mcs51/ changed these files in order to create an
11253 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11254 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11255 following files to include the previous two files: aslink.dsp,
11256 Makefile.aslink, Makefile.bcc, and Makefile.in.
11258 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11259 .adb instead of .cdb
11261 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11263 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11264 value from option --iram-size.
11266 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11268 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11271 2002-09-18 <wiml AT hhhh.org>
11273 * SDCClrange.h: exposed setFromRange() and setToRange()
11274 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11275 packRegsForAccUse() (bug 542397)
11276 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11277 multiple times and emitting the fetch operations more than once
11278 added aopGetUsesAcc() function to allow binary operators to
11279 fetch their operands in the correct order; made genMinus() emit
11280 compact code for X = LITERAL - Y
11282 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11283 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11284 sprintf() in line 1267.
11286 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11287 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11290 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11291 Changes to aslink (All the changes are marked with 'JCF'):
11293 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11296 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11297 area BSEG. Also moves, if possible, the DATA area down into the internal
11298 ram so more space is available.
11300 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11303 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11304 not bytes. Function summary() which creates a memory usage summary
11305 file with extension .mem. Reports of overlaping stack and small stack
11306 size. If the space for the stack is less than 16 bytes aslink trows a
11309 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11310 the 8051. Option 'y' for memory summary output file.
11312 Changes to sdcc (All the changes are marked with 'JCF'):
11314 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11316 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11317 overlaying area for it (uses RegBankUsed[4]).
11319 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11320 bank zero as used by default. By default aslink locates the stack
11321 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11322 the creation of the .mem file. Delegates the allocation of data area
11323 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11324 the begining of the stack area to aslink.
11326 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11327 glue() in SDCCglue.c creates an area for it.
11329 2002-09-03 Borut Razem <borut.razem AT siol.net>
11330 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11331 sdcc/src/pic/glue.c:
11332 introduced atexit() handler for teporay files removal in case of
11333 errors, assertions, ...
11335 2002-08-29 Borut Razem <borut.razem AT siol.net>
11336 * sdcc/support/cpp2/auto-host_vc_in.h:
11337 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11338 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11339 Maybe there is a similar problem with BORLANDC? It should be checked!
11341 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11342 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11343 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11344 was not executed, and the compiler (cl) launched a warning:
11345 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11347 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11348 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11350 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11351 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11353 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11354 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11355 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11356 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11357 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11358 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11359 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11360 - added Release configuration in VS projects
11361 - review of compiler an linker options
11362 - VC .exe files are generated in bin_vc directory, not to interfere
11363 with binaries generated from other projects (cygwin, mingw, bcc ...)
11365 * sdcc/src/yacc.dsp: added
11367 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11368 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11369 and insert the version number definitions from .version
11371 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11373 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11374 added - genarate auto-host.h using auto-host_vc_in.h as template
11377 removed from CVS, generated automatically
11379 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11380 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11382 2002-08-11 Borut Razem <borut.razem AT siol.net>
11383 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11385 2002-08-10 Borut Razem <borut.razem AT siol.net>
11386 * src/SDCCmain.c (main):
11387 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11388 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11389 The consequence was that some temporary files were not removed.
11392 unification of code in functions tempfilename() and tempfile():
11393 function tempnam() is defined in Visual Studio 6.0 and .NET
11395 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11397 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11398 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11399 - removed compiler command line option /WX: Treats all warnings as errors
11400 - update a list of source files, included into the project
11402 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11403 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11404 changed project type to Generic Project so that can be correcly converted to VS.NET project
11406 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11408 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11410 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11412 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11413 added return 0 statements after assert() to make compiler happy
11415 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11416 added newline in the def file to keep MSC compiler satisfied
11418 * sdcc/src/z80/gen.c:
11419 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11420 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11421 - solved MSC error in function aopDump()
11423 * sdcc_vc.h: define PREFIX as "\\sdcc"
11425 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
11426 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

11429 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
11430 - Rewrote the register banking algorithm.
11431 - Added pCode live-range analysis to registers (for now, only non-used and
11432 singly-used registers optimized away)
11434 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
11436 * 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/main.c: Added force callee saves for jaune.
11461 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
11463 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
11465 2002-03-28 Johan Knol <johan AT balder>
11467 * src/SDCCval.c: fixed bug #532436
11469 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11471 Added "char *Processor" field to the port structure.
11474 Added -p option. Allows port dependent processor to be specified.
11477 Initialized the new field char *Processor field to NULL in all ports
11480 Compiler generated registers for interrupt context saving
11481 were not getting allocated.
11483 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
11486 Fixed left shift. Will promote the left side of a left shift
11487 if a) left shifting more than size of operand or b) when assigned
11488 to something size > size of left side
11490 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11492 tons of changes. Register allocation has been
11493 rewritten. Added customization for the various PICs. Flow
11494 analysis is restructured. ...
11496 * src/pic/device.h:
11499 * src/pic/device.c:
11500 Added. device.c is a PIC port hack to accomodate variations
11503 2002-03-13 Michael Hope <michaelh AT vroom>
11505 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
11507 2002-03-04 johanknol <johanknol AT manik>
11509 * /src/SDCCval.c: fixed
11511 const unsigned char arr[][2] = { { 0, 1 } };

11598 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
11600 * sdcc/src/SDCCloop.c:
11601 Previous fix was not good. basic blocks that have "break" or "return" are
11602 not really partof a loop , but live ranges used in these blocks should
11603 be live thru the entire loop, so set partOfLoop but don't add them to
11606 2002-02-21 <johan AT FRIJA>
11608 * src/SDCCcse.c: fixed bug #514308
11610 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
11613 Fixed BUG #519583. If a conditional block ended in a return/break
11614 statement inside a loop, it was not being considered part of the loop.
11616 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
11618 2002-02-10 Karl Bongers <karl AT turbobit.com>

11622 with lots of comments and notes.
11624 * device/examples/test2.c:
11625 Fix bug, "red" variable not being initialized(compiler complained).
11627 * device/examples/Makefile, examples/test3.c:
11628 Add Makefile in device/examples folder, compiles test3.c
11629 for use as a multiple module SDCDB test case.
11631 * sim/ucsim/cmd.src/cmdset.cc:
11632 Took out debug printfs in ucsim "next" command.
11634 * sim/ucsim/xa.src:
11635 Karl and Johan start ucsim XA support. Most dissassembly working,
11636 about 75% emulation done(plenty of work remaining).
11638 * sim/ucsim/z80.src:
11639 Add Z80 support to ucsim, add test-ucz80 regression test,
11640 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
11641 Notice z80 compiler fails on examples/test3.c/crc code.
11643 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>
11645 * src/mcs51/gen.c, src/mcs51/main.c, src/mcs51/ralloc.c:

11653 from a memory mapped port
11654 2) added __builtin_memcmp
11655 3) added __builtin_swapw swap bytes of a short
11657 * src/ds390/gen.c, src/ds390/gen.h, src/ds390/ralloc.c:
11658 1) handle multiple send & receives from register bank1
11659 2) ralloc can now allocate DPTR1 to some liveRanges
11661 * src/SDCCsymt.c, src/SDCCsymt.h:
11662 changes to handle multiple sends & receives
11664 * src/SDCCptropt.h:
11665 added some pointer arithmetic optimization
11667 * src/SDCCptropt.c:
