1784 * install-sh: fix bug #1204398 by setting umask 0022
1785 * device/lib/Makefile: separate build of z80 and gbz80 lib
1787 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1789 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1790 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1792 One basic decision: e.g. src/clean.mk includes further files. In order
1793 to make this work there are two solutions:
1794 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1795 run configure on them. This way they can use
1796 'include $(srcdir)/port-clean.mk'
1797 - always include clean.mk by the Makefile at the same level. To avoid
1798 that `make clean` tries to include and build Makefile.dep the
1799 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1800 implemented, because now even `make uninstall` doesn't create
1801 Makefile.in. clean.mk could be eliminated by pasting it in
1804 * debugger/mcs51/Makefile.in: build own objects from library sources
1805 (SLIB, SDCC) in current directory
1807 * configure, configure.in: renamed --disable-device-lib-build in
1808 --disable-device-lib; added --enable-doc, the required tools are
1809 searched by configure; added result message; the toolchain for the
1810 belonging ports are now only built, if the port is enabled.
1812 * support/regression/*: all output is written in directory gen, because
1813 the fwk and ports directories don't livet in the build tree using vpath
1815 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1816 --disable-device-lib, added --enable-doc, added section VPATH
1818 * sim/ucsim/configure.in,
1819 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1820 z80 are enabled by default
1822 2006-04-24 Raphael Neider <rneider AT web.de>
1824 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1825 to config word, "pic14_"-prefixed some extern functions
1826 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1827 config word has been found
1828 * src/pic/device.h: added prototypes
1829 * src/pic/pcode.c: added "pic14_"-prefix where needed

2138 call to allocReg, not by manually allocating a new one,
2139 (pic16_assignRegisters): now before going through the register
2140 allocating functions mark all registers as free. This eliminates some
2141 side effects resulting from peephole parser done earlier in the backbone

2209 _main (this should take care the --main-return command line option in
2211 (genOr): removed some legacy pic-port instructions,
2212 * src/pic16/genarith.c (genAddLit): re-enabled old code because
2213 performing operations with SFR's causes data to be written more than
2214 once to each SFR. Perhaps SFRs should be handled in special cases...
2215 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
2217 * src/pic16/main.c (_process_pragma): stack bound checking did not take
2218 into account for stack starting position,
2219 (struct OPTIONS pic16_optionsTable): added command line argument
2220 --extended or -y for Extended Instruction Support,
2221 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
2222 (deassignLRs): *** perhaps the most important change, old 'for' code
2223 (commented out for reference), didn't account for some registers which
2224 were left marked 'not free' after a pointer operation. The change
2225 reduces register usage a lot in some cases

4498 * src/SDCCglobal.h (struct options),
4500 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
4501 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
4502 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
4503 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
4504 always available in leading double underscore form. The C99 support is
4505 mostly missing, but it's a start.
4506 * support/regression/tests/bug-227710.c: fixed nonconforming use of
4507 reserved identifier "__data".

4585 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
4587 * device/lib/printf_large.c: removed inline assembly for portability and
4588 readability. Use printf_fast if speed or size are more important.
4589 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4590 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4592 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4594 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4595 prevent compiler warning
4597 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4599 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4600 moved to level 0 and declared as static. Also they are explicit
4601 placed in access bank. This was necessery because some times they
4602 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4603 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4604 optimizations. Currently only compare to unsigned char is implemented,
4605 * src/pic16/gen.c: added fReturnIdx array,
4606 * (struct resolvedIfx) is moved to gen.h and made public,
4607 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4608 * (aopForSym): added an optimization to directly store in stack of
4609 the operand of a SEND iCode,
4610 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4611 but as registers instead (AOP_REG) using the fReturnIdx array,
4612 * (pic16_freeAsmop): remove the freed register from the
4613 _G.sregsAlloc field,
4614 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4615 a compare of 'WREG',
4616 * (pic16_popGetTempRegCond): changed function prototype, now
4617 function takes also a bitVector argument v which holds the current
4618 set of registers that are allocated for stack access by aopForSym,
4619 registers allocated in aopForSym for accessing stack symbols are not
4620 any more part of the functions usedRegs field,
4621 * (genCall): some times aopOp is called for a stack variable to be
4622 send, aopForSym might perform the push, if this is true make sure
4623 that genCall doesn't push the variable twice by testing _G.resDirect,
4624 * (genFunction): changed testing for unspecified interrupt number
4625 from 256 to INTNO_UNSPEC,
4626 * modified selection scheme of frame pointer generation. Previously
4627 if function did use local registers a frame pointer was generated,
4628 now a frame pointer is generated only if function has arguments
4629 (that need PLUSW2 register access), or has stack arguments, or the
4630 compiler is not instructed to omit the frame pointer,
4631 * (genEndFunction): before restoring local registers that were saved
4632 in the function preamble, also restore the registers that *might*
4633 have been allocated for stack access,
4634 * (genRet): removed some old comments,
4635 * (genCmp, the active (RN's) version): added a call to the
4636 pic16_genCmp_special function to perform the compare with a more
4637 robust and optimized way,
4638 * (genInline): a feature has been added in inline code generation,
4639 which allows a wildcard variable substitution when writing inline
4640 assembly. Code is incomplete and experimental therefore undocumented,
4641 * (genCast): changed order of aopOp for result and right to allow
4642 aopForSym to directly load the result if possible,
4643 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4644 perform an optimized compare on some selected special occasions,
4645 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4646 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4647 generate an IVT any more,
4648 * src/pic16/main.c (pic16_optionsTable): added command line option
4650 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4651 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4653 * src/pic16/NOTES: Raphael Neider added in list of active developers
4654 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4655 jumptable_end to prevent bug #,
4656 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4657 inCond and outCond fields,
4658 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4659 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4660 turn off register spilling,
4661 * (packRegsForOneUse): synced with other ports' versions although it
4662 is not used currently,
4663 * (pic16_packRegisters): added an optimization while reading
4664 structure bitfields, some registers may be saved (malloc code is
4665 decreased by 80 bytes)
4667 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4669 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4670 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4671 this can be optimized more?
4673 2005-03-10 Raphael Neider <rneider AT web.de>
4675 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4676 genNearPointerGet): (hopefully) fixed access to bitfields via
4677 pointers (p->bitN = x; and x = p->bitN; failed)
4679 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

4722 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
4723 to keep the correct label reference count when adding/removing references
4724 to labels. A peephole file using this is appended to patch #1144962.
4726 2005-02-14 Raphael Neider <rneider AT web.de>

5311 Adding support for replacing ljmps with sjmps in jumptables
5312 generated for switch statements. For now you need to set the
5313 environment variable SDCC_SJMP_JUMPTABLE to enable this.
5314 Now 4 algorithms for mcs51 jumptable generation are used:
5315 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
5316 addresses loaded pc-relative for up to 112 cases and stack-pushing
5317 target addresses loaded with offset from dptr for up to 256 cases.

5347 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
5349 * added libc directory. The current version of LibC contains string
5350 functions, ctype functions and macros and some functions of the
5351 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
5352 be extensively tested in the future. Standard disclaimer here.
5353 Library is not automatically build yet. But one can build it by
5354 invoking 'make' inside the libc directory.

5365 * (pic16_storeForReturn): optimized return of 0,
5366 * (genCmp): experimental code for new genCmp which uses PIC18's
5367 special compare&skip instructions. Initial tests fail some times
5368 with variables grater than 1 byte in size, so new code is disabled,
5369 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5371 * (genCast): began a fix to optimize the casting of a bit to another
5372 bit, now assigning a bitfield to another bitfield will fail, sorry,

5381 and 1 for banking instruction,
5382 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
5383 caused stop processing pCodes after a inline assembly block,
5384 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

5386 registers when it shouldn't,
5387 * src/pic16/ralloc.c (allocReg): add preliminary support for
5388 supporting a limited set of temporary registers,
5390 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5392 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,

5396 (genFunction): optimize RECEIVE iCodes in reentrant functions
5398 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8281 virus/worm forged address usage.
8283 2004-01-27 Bernhard Held <bernhard AT bernhardheld.de>
8285 Fixed promotion, it should be done on AST level:

8309 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
8311 * src/SDCCast.c: added an additional type flow in decorateType() of
8312 opposite direction, see feature request #860006; it's enabled at runtime
8313 by setting the environment variable SDCC_NEWTYPEFLOW
8314 * src/SDCCast.h: changed prototype of decorateType()
8315 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
8316 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from

8348 added support for multiple code pages and multiple RAM banks on the
8349 PIC 14 port. The ASM files now no longer simply assume all the
8350 code / RAM are in the same page / bank. This means the linker can
8351 safely allocate code/RAM of separate ASM files to different pages/banks.
8352 * doc/sdccman.lyx: added Slade's tips
8353 * src/mcs51/peeph.def: fixed bug #880768

8395 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
8397 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
8398 loaded with the linker search paths (-L arguments) and the libraries
8399 to be linked with the current source (-l arguments). Changes
8400 currently will affect only the pic16 port.
8401 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8402 include path the port specific paths and port specific libraries,
8403 * gplink command now contains the $3 argument,
8404 * src/pic16/device.h,
8405 * src/pic16/device.c,: structure PIC_device is made public and
8406 renamed to PIC16_device, the same for variable Pics which is renamed

8421 Documenting changes from previous commits.
8422 * configure.in (version 1.56),
8423 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8424 when generating output files to configure the pic16 library,
8425 but now I've commented it out, since gputils aren't installed in the
8426 SF compile farm, so library won't compile
8428 * device/lib/Makefile.in (version 1.56): initially I've added in
8429 target 'all' the prerequestive 'model-pic16' so it compiled the
8430 pic16 library, but now I've commented it out for the same reasons
8432 * added targets 'model-pic16' and 'objects-pic16' to compile the
8434 * added target 'port-specific-objects-pic16' to handle the
8435 generated libraries and copy them into the build/ directory
8436 * added target 'clean-intermediate-pic16' to clean intermediate
8437 files into pic16 directory
8438 * in target 'installdirs' added line to create directory pic16 in
8439 the installation path
8441 * device/include/Makefile.in (version 1.11): in target 'install'
8442 added lines to copy all header files to installation path,
8443 * in target 'installdirs' added line create directory for pic16
8444 headers in the installation path

8459 * src/z80/main.c (_parseOptions): fixed the portmode= command line
8460 option so that it actually works. Made it specific to the z80, since
8461 the gbz80 doesn't have these kinds of I/O ports.
8463 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8465 * device/include/z180.h,

8487 Mainly changes to support compilation of the device libraries
8488 * src/pic16/device.c: stack is allocated via symbol and not
8489 via literal number. The symbol is placed in the corresponding
8490 position of the data ram
8491 * (pic16_dump_section): relocatable and absolute uninitialized
8492 data are now emitted in sorted order to reduce section naming,
8493 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
8494 weren't marked as being in the access bank,
8496 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
8498 Added portion of GNU PIC Library under the directory
8499 device/include/pic16 and device/lib/pic16. These files
8500 contain the declarations of SFRs for the PIC18Fxx2 devices.
8501 The directory is initialized via configure from toplevel.

8531 all over. Telling LaTeX to be less strict with word spacing
8532 to better keep the right margin. Changed some notes about
8533 maintainance of the ports in section 3.2.1 - is it OK like this?

8729 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8731 PIC16 port related changes:
8732 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8733 added variable stackPos,
8735 * gen.c: genCall, assignResultValue: added support for
8736 pushing/retrieving function parameters to/from stack,
8737 genFunction,genEndFunction: setup stack frame for the
8739 genAddrOf: will be changed according to bug 863624
8741 * added files genutils.c and genutils.h which contain gen*
8742 debugged and optimised functions extracted from gen.c
8744 * glue.c: added variable 'externs' which holds extern symbols,
8745 pic16emitRegularMap: is modified to properly handle relocatable
8746 symbols under the new scheme,
8747 pic16createInterruptVect: is modified
8748 pic16printPublics: is modified to emit 'global' assembler directives,
8749 added pic16_printExterns to print extern symbols,
8750 pic16glue: initializes stack/frame pointer in the beginning of
8751 the assembly output. Temporary hack, will be corrected later,
8752 because gplink yet does not support stack and SDCC does not
8753 yet support a type of crt0.o object to create the final binary.
8755 * Removed many lines that contain 8051 legacy code.
8756 * The code is finally placed under a 'code' directive.
8757 * Added port specific options.
8759 * _process_pragma: simplified since now we do not need *special*
8760 include file to define SFR registers. But a separate header
8761 will be needed. This will be developed later.
8762 * _pic16_parseOptions: added, parses port specific options:
8763 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8764 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8765 --preplace-udata-with=
8767 * _pic16_setDefaultOptions: modified to initialize section names,
8768 but hack is temporarly out of order since it needs improvement.
8769 * _pic16_genAssemblerPreamble: configuration words are emitted by
8770 their address instead of their name. This part is incomplete and
8771 supports only the 18Fxx2 devices. Other devices will emit an error
8772 during assembly since they do not contain the same set of config
8774 * _pic16_genIVT: is modified,
8776 * pcode.c: added definitions for some hardware registers that are needed
8778 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8779 All PCI entries are updated. Now LFSR is supported.
8780 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8781 * added pic16_newpCodeOpLit2 to support instructions with
8782 two literal arguments
8783 * pic16_pCode2str: corrected code that emits assembler instructions
8784 with two literal operands and those that have an access bit modifier
8785 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8786 this fixes a bug which caused some labels to be lost, when an
8787 assembler directive was added, i.e. banksel,
8788 * pic16_FixRegisterBanking: improved logic that causes the insertion
8790 * InlineFunction: functions that are called once, are not any more
8791 inlined. This can be a port option in the future,
8793 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8795 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8796 hold the corresponding uninitialized symbols,
8797 * pic16_allocProcessorRegister: registers have explicit marked the
8799 * pic16_allocInternalRegister: registers are explicit marked as
8801 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8802 processing list, so bit registers were lost,
8805 * ralloc.h: added field 'accessBank' and original symbol operand
8806 in register definition,
8807 * removed the field isMapped from register definition,
8809 ** Several functions have been removed from various sources:
8810 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8811 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8812 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8813 pic16_assignRelocatableRegisters
8815 ** others have been introduced:
8816 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8817 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8819 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8821 * support/scripts/inc2h.pl: changed definition of BIT_AT
8822 to emit 'sbit at' instead of 'bit at'. This was a request.
8824 PIC16 port related preliminary changes:
8825 * gen.c: prefixed function popRegFromString with
8826 pic16_ and all references to it corrected
8827 * pcode.c: all pic16_pc_* hardware registers prefixed
8828 with underscore (_),
8829 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8830 * ralloc.c: newReg(): when register is REG_SFR then
8831 set address to rIdx,
8832 pic16_allocProcessorRegister(): marks register wasUsed=0
8833 pic16_writeUsedRegs(): added a call to assign processor
8834 registers via pic16_assignFixedRegisters
8836 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8838 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8839 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8840 variables in unused register banks. Also the SSEG is placed
8841 wherever there is enough space for it, and IDATA can be anywhere
8842 in internal RAM. For now compile using -Wl-Y[stack_size].
8843 The mem file is different for this option as well, since it
8844 makes no sense of talking about DSEG lenght.
8846 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8848 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8849 in certain cases, e.g. when ROM assignment, patch provided
8850 from Albert den Haan.

9091 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9093 * src/SDCCast.c (decorateType): disabled a transformation I added in
9094 revision 1.188 (access to fields of a structure at an absolute address);
9095 it breaks with bitfields, extern declarations, and gcse analysis.
9096 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
9097 could be assigned through a pointer, so don't complain.
9098 * src/SDCCast.c (astErrors),

9202 * src/mcs51/main.c: started fixing bug #737001 (SDCC not clearing
9203 uninitialized variables) for the mcs51. Set environment variable

9205 xdata initialization slightly shorter
9207 2003-11-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9857 copied from genNearPointerSet()
9858 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
9859 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

9875 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9876 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9877 type for bits was changed. It resulted in bit variables becoming
9878 global, which is not permitted in PIC 14 assembly output.

9895 A few small changes that speed up the peephole optimizer.
9899 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9901 Try to make the peephole optimizer smarter by maintaining
9902 an association between the assembly source code and the
9903 iCodes that originated them. Put this information to use
9904 with a new peephole rule condition "notVolatile" so that
9905 the rules can be aggressive yet still safe.
9910 * src/mcs51/peeph.def
9912 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9916 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9917 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9918 if the left or right operand symbols have the accuse flag set.
9920 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9922 Changed the type of the result of the ! (NOT) operator to char;
9923 previously it returned the same type as the source. This allows
9924 us to eliminate all the genFloatNot functions (all of its target
9925 implementations were very buggy) since !float can use the same

9937 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9938 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9939 during interrupts. Ensure WSAVE is located at a shared bank address.
9940 2. Fixed page selection in some places
9941 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9942 the registers name strings.
9943 4. Fixed "signed / unsigned compare" compiler warnings.
9944 5. The PIC port manages its own allocation of the general purpose
9945 registers, but makes no attempt to reuse them. As a result when
9946 compiling it soon runs out of general purpose registers. Some
9947 additional code was added to the files pcode.c and device.c to walk
9948 through the function call tree and rename the registers so that they
9958 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9959 genPlus() & genMinus() when the result is the same as left or right

9965 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9967 Made bitfield a distinct type from bit so that bitfields
9968 convert as per ANSI C and bits retain their traditional
9969 boolean style behaviour. Implemented bitfield support in
9977 * src/ds390/gen.c: bit v bitfield split
9978 * src/z80/gen.c: New support for bitfields
9979 * support/regression/tests/bitfields.c: reenabled z80,
9982 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9984 Rules 246.x, 247.x relate to bitfields, the others speed up
9985 access to xdata mapped I/O devices.
9987 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9989 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9991 Cleaned up genPackBits and genUnpackBits and added two helper
9992 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9993 for literal assignments in genPackBits (thanks to Frieder for
9999 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10001 Fixed bug #748310 (pointer to function type mishandled when the
10002 function name is omitted). Also fixed a SIGSEGV when a function
10003 attribute (reentrant, etc) is used on a non-function or on a
10004 function but misplaced before the parameter list.
10006 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
10008 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
10009 * support/Util/SDCCerr.h,

10031 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10033 Made the constant following the "interrupt" keyword optional. If
10034 omitted, the function will not automatically be given an entry
10035 in the interrupt vector table (similar to #pragma NOIV, but
10036 less syntacticly kludgy). The interrupt number is also now
10037 range checked. Also fixed a bug in the high order bit example

10053 * src/SDCCsymt.c (computeType): literals are handled the same way as any
10055 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
10056 be re-activated by defining REDUCE_LITERALS)
10057 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
10058 unsigned, but are signed by default
10059 * src/SDCCval.c (constVal): rearranged
10060 * src/SDCCval.c (valMod): preliminary fix

10568 messages from optionsTable when a port is not configured, added
10569 support for the PIc16 port in the ports table, when executing
10570 the compiler with no port specified on command line, a default
10571 port is selected with the new macro DEFAULT_PORT which is
10572 defined in port.h, in setDefaultOptions() linkOptions is removed
10573 from initialization assignment, since now it is a set,
10574 parseCmdLine uses setParseWithComma for linkOptions, in
10575 linkEdit() linkOptions are accessed with new function indexSet()
10576 which returns the i'th item of a set variable. See SDCCset.c, in
10577 linkEdit() when calling buildCmdLine(), added linkOptions as
10578 last argument. Now users can pass arguments to gplink via the
10579 -Wl option, main() uses pic16glue() to glue up pic16 programs

10593 gpasm complaining and test the linkage with gplink, _linkCmd and
10594 _asmCmd changed to be more gplink and gpasm friendly
10595 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10596 produced an error when parsed, peep rule 12 is added to utilize
10597 movff, but it is commented out since the pCode does not support
10598 yet a command with 2 address arguments

11620 2003-01-07 <johan AT balder>
11622 * src/SDCCast.c (decorateType): fixed bug #600035
11624 2003-01-07 Bernhard Held <bernhard AT bernhardheld.de>
11625 * as/mcs51/lkmem.c: added several l-modifiers to printf to remove warnings
11626 * as/mcs51/lkaomf51.c: #include <ctype.h> to remove warnings
11627 * src/pic/main.c (_hasNativeMulFor): outcommented unused variables to remove warnings
11628 * src/pic/pcode.c: outcommented unused variable to remove warnings

11635 2003-01-06 <johan AT balder>
11637 * src/SDCCicode.c: fixed array add
11639 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
11640 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
11641 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
11643 2003-01-04 <johan AT balder>
11645 * src/SDCCval.c (getNelements): fixed the initialized array of structures
11647 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11648 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
11650 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
11651 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
11652 * support/regression/tests/bug-524697.c: fit mem usage into 8032
11654 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
11655 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
11657 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
11658 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
11660 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
11661 * src/mcs51/main.c: removed {bindir}{sep} from aslink
11663 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11665 * in /sdcc/as/mcs51/ changed these files in order to create an
11666 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11667 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11668 following files to include the previous two files: aslink.dsp,
11669 Makefile.aslink, Makefile.bcc, and Makefile.in.
11671 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11672 .adb instead of .cdb
11674 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11676 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11677 value from option --iram-size.
11679 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11681 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11684 2002-09-18 <wiml AT hhhh.org>
11686 * SDCClrange.h: exposed setFromRange() and setToRange()
11687 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11688 packRegsForAccUse() (bug 542397)
11689 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11690 multiple times and emitting the fetch operations more than once
11691 added aopGetUsesAcc() function to allow binary operators to
11692 fetch their operands in the correct order; made genMinus() emit
11693 compact code for X = LITERAL - Y
11695 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11696 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11697 sprintf() in line 1267.
11699 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11700 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11703 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11704 Changes to aslink (All the changes are marked with 'JCF'):
11706 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11709 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11710 area BSEG. Also moves, if possible, the DATA area down into the internal
11711 ram so more space is available.
11713 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11716 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11717 not bytes. Function summary() which creates a memory usage summary
11718 file with extension .mem. Reports of overlaping stack and small stack
11719 size. If the space for the stack is less than 16 bytes aslink trows a
11722 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11723 the 8051. Option 'y' for memory summary output file.
11725 Changes to sdcc (All the changes are marked with 'JCF'):
11727 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11729 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11730 overlaying area for it (uses RegBankUsed[4]).
11732 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11733 bank zero as used by default. By default aslink locates the stack
11734 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11735 the creation of the .mem file. Delegates the allocation of data area
11736 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11737 the begining of the stack area to aslink.
11739 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11740 glue() in SDCCglue.c creates an area for it.
11742 2002-09-03 Borut Razem <borut.razem AT siol.net>
11743 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11744 sdcc/src/pic/glue.c:
11745 introduced atexit() handler for teporay files removal in case of
11746 errors, assertions, ...
11748 2002-08-29 Borut Razem <borut.razem AT siol.net>
11749 * sdcc/support/cpp2/auto-host_vc_in.h:
11750 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11751 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11752 Maybe there is a similar problem with BORLANDC? It should be checked!
11754 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11755 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11756 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11757 was not executed, and the compiler (cl) launched a warning:
11758 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11760 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11761 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11763 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11764 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11766 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11767 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11768 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11769 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11770 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11771 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11772 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11773 - added Release configuration in VS projects
11774 - review of compiler an linker options
11775 - VC .exe files are generated in bin_vc directory, not to interfere
11776 with binaries generated from other projects (cygwin, mingw, bcc ...)
11778 * sdcc/src/yacc.dsp: added
11780 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11781 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11782 and insert the version number definitions from .version
11784 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11786 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11787 added - genarate auto-host.h using auto-host_vc_in.h as template
11790 removed from CVS, generated automatically
11792 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11793 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11795 2002-08-11 Borut Razem <borut.razem AT siol.net>
11796 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11798 2002-08-10 Borut Razem <borut.razem AT siol.net>
11799 * src/SDCCmain.c (main):
11800 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11801 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11802 The consequence was that some temporary files were not removed.
11805 unification of code in functions tempfilename() and tempfile():
11806 function tempnam() is defined in Visual Studio 6.0 and .NET
11808 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11810 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11811 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11812 - removed compiler command line option /WX: Treats all warnings as errors
11813 - update a list of source files, included into the project
11815 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11816 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11817 changed project type to Generic Project so that can be correcly converted to VS.NET project
11819 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11821 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11823 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11825 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11826 added return 0 statements after assert() to make compiler happy
11828 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11829 added newline in the def file to keep MSC compiler satisfied
11831 * sdcc/src/z80/gen.c:
11832 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11833 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11834 - solved MSC error in function aopDump()
11836 * sdcc_vc.h: define PREFIX as "\\sdcc"
11838 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
11839 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
11841 2002-06-22 Scott Dattalo <scott AT dattalo.com>
11842 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
11843 - Rewrote the register banking algorithm.
11844 - Added pCode live-range analysis to registers (for now, only non-used and
11845 singly-used registers optimized away)
11847 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
11849 * 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.

11866 * device/lib/z80/printf.c (sprintf): Added.
11868 * src/z80/ralloc.c (packRegisters): Disabled pack HL use for GB as it's broken.
11870 * src/z80/peeph.def: Added transpose redundent load rule.
11872 * src/z80/main.c: Added force callee saves for jaune.
11874 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
11876 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
11878 2002-03-28 Johan Knol <johan AT balder>
11880 * src/SDCCval.c: fixed bug #532436
11882 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11884 Added "char *Processor" field to the port structure.
11887 Added -p option. Allows port dependent processor to be specified.
11890 Initialized the new field char *Processor field to NULL in all ports
11893 Compiler generated registers for interrupt context saving
11894 were not getting allocated.
11896 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
11899 Fixed left shift. Will promote the left side of a left shift
11900 if a) left shifting more than size of operand or b) when assigned
11901 to something size > size of left side
11903 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11905 tons of changes. Register allocation has been
11906 rewritten. Added customization for the various PICs. Flow
11907 analysis is restructured. ...
11909 * src/pic/device.h:
11912 * src/pic/device.c:
11913 Added. device.c is a PIC port hack to accomodate variations
11916 2002-03-13 Michael Hope <michaelh AT vroom>
11918 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
11920 2002-03-04 johanknol <johanknol AT manik>
11922 * /src/SDCCval.c: fixed
11924 const unsigned char arr[][2] = { { 0, 1 } };
11925 t18.c:1: error: Initializer element is not constant

12011 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
12013 * sdcc/src/SDCCloop.c:
12014 Previous fix was not good. basic blocks that have "break" or "return" are
12015 not really partof a loop , but live ranges used in these blocks should
12016 be live thru the entire loop, so set partOfLoop but don't add them to
12019 2002-02-21 <johan AT FRIJA>
12021 * src/SDCCcse.c: fixed bug #514308
12023 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
12026 Fixed BUG #519583. If a conditional block ended in a return/break
12027 statement inside a loop, it was not being considered part of the loop.
12029 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
12031 2002-02-10 Karl Bongers <karl AT turbobit.com>

12035 with lots of comments and notes.
12037 * device/examples/test2.c:
12038 Fix bug, "red" variable not being initialized(compiler complained).
12040 * device/examples/Makefile, examples/test3.c:
12041 Add Makefile in device/examples folder, compiles test3.c
12042 for use as a multiple module SDCDB test case.
12044 * sim/ucsim/cmd.src/cmdset.cc:
12045 Took out debug printfs in ucsim "next" command.
12047 * sim/ucsim/xa.src:
12048 Karl and Johan start ucsim XA support. Most dissassembly working,
12049 about 75% emulation done(plenty of work remaining).
12051 * sim/ucsim/z80.src:
12052 Add Z80 support to ucsim, add test-ucz80 regression test,
12053 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
12054 Notice z80 compiler fails on examples/test3.c/crc code.
12056 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>
12058 * src/mcs51/gen.c, src/mcs51/main.c, src/mcs51/ralloc.c:
12059 Added support for --parms-in-bank1
12061 * src/ds390/peeph.def:
12062 added a few more peephole optimzations
12064 * src/ds390/main.c:
12065 1) added __builtin_inp & __builtin_outp used to read in data of given length
12066 from a memory mapped port
