1492 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
1493 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
1494 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,

1577 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1579 * device/lib/printf_large.c: removed inline assembly for portability and
1580 readability. Use printf_fast if speed or size are more important.
1581 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1582 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1584 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1586 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1587 prevent compiler warning
1589 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1591 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1592 moved to level 0 and declared as static. Also they are explicit
1593 placed in access bank. This was necessery because some times they
1594 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1595 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1596 optimizations. Currently only compare to unsigned char is implemented,
1597 * src/pic16/gen.c: added fReturnIdx array,
1598 * (struct resolvedIfx) is moved to gen.h and made public,
1599 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1600 * (aopForSym): added an optimization to directly store in stack of
1601 the operand of a SEND iCode,
1602 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1603 but as registers instead (AOP_REG) using the fReturnIdx array,
1604 * (pic16_freeAsmop): remove the freed register from the
1605 _G.sregsAlloc field,
1606 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1607 a compare of 'WREG',
1608 * (pic16_popGetTempRegCond): changed function prototype, now
1609 function takes also a bitVector argument v which holds the current
1610 set of registers that are allocated for stack access by aopForSym,
1611 registers allocated in aopForSym for accessing stack symbols are not
1612 any more part of the functions usedRegs field,
1613 * (genCall): some times aopOp is called for a stack variable to be
1614 send, aopForSym might perform the push, if this is true make sure
1615 that genCall doesn't push the variable twice by testing _G.resDirect,
1616 * (genFunction): changed testing for unspecified interrupt number
1617 from 256 to INTNO_UNSPEC,
1618 * modified selection scheme of frame pointer generation. Previously
1619 if function did use local registers a frame pointer was generated,
1620 now a frame pointer is generated only if function has arguments
1621 (that need PLUSW2 register access), or has stack arguments, or the
1622 compiler is not instructed to omit the frame pointer,
1623 * (genEndFunction): before restoring local registers that were saved
1624 in the function preamble, also restore the registers that *might*
1625 have been allocated for stack access,
1626 * (genRet): removed some old comments,
1627 * (genCmp, the active (RN's) version): added a call to the
1628 pic16_genCmp_special function to perform the compare with a more
1629 robust and optimized way,
1630 * (genInline): a feature has been added in inline code generation,
1631 which allows a wildcard variable substitution when writing inline
1632 assembly. Code is incomplete and experimental therefore undocumented,
1633 * (genCast): changed order of aopOp for result and right to allow
1634 aopForSym to directly load the result if possible,
1635 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1636 perform an optimized compare on some selected special occasions,
1637 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1638 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1639 generate an IVT any more,
1640 * src/pic16/main.c (pic16_optionsTable): added command line option
1642 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1643 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1645 * src/pic16/NOTES: Raphael Neider added in list of active developers
1646 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1647 jumptable_end to prevent bug #,
1648 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1649 inCond and outCond fields,
1650 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1651 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1652 turn off register spilling,
1653 * (packRegsForOneUse): synced with other ports' versions although it
1654 is not used currently,
1655 * (pic16_packRegisters): added an optimization while reading
1656 structure bitfields, some registers may be saved (malloc code is
1657 decreased by 80 bytes)
1659 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1661 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1662 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1663 this can be optimized more?
1665 2005-03-10 Raphael Neider <rneider AT web.de>
1667 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1668 genNearPointerGet): (hopefully) fixed access to bitfields via
1669 pointers (p->bitN = x; and x = p->bitN; failed)
1671 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

1714 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
1715 to keep the correct label reference count when adding/removing references
1716 to labels. A peephole file using this is appended to patch #1144962.
1718 2005-02-14 Raphael Neider <rneider AT web.de>

2303 Adding support for replacing ljmps with sjmps in jumptables
2304 generated for switch statements. For now you need to set the
2305 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2306 Now 4 algorithms for mcs51 jumptable generation are used:
2307 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
2308 addresses loaded pc-relative for up to 112 cases and stack-pushing
2309 target addresses loaded with offset from dptr for up to 256 cases.

2339 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
2341 * added libc directory. The current version of LibC contains string
2342 functions, ctype functions and macros and some functions of the
2343 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2344 be extensively tested in the future. Standard disclaimer here.
2345 Library is not automatically build yet. But one can build it by
2346 invoking 'make' inside the libc directory.
2347 * added ADC library under libio. Preliminary version yet.

2357 * (pic16_storeForReturn): optimized return of 0,
2358 * (genCmp): experimental code for new genCmp which uses PIC18's
2359 special compare&skip instructions. Initial tests fail some times
2360 with variables grater than 1 byte in size, so new code is disabled,
2361 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2363 * (genCast): began a fix to optimize the casting of a bit to another
2364 bit, now assigning a bitfield to another bitfield will fail, sorry,
2365 * src/pic16/main.c: disabled the use of lr-support feature,
2366 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

2372 * (isBankInstruction): modified to return 0 for no banking instruction,
2373 and 1 for banking instruction,
2374 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
2375 caused stop processing pCodes after a inline assembly block,
2376 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
2377 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
2378 registers when it shouldn't,
2379 * src/pic16/ralloc.c (allocReg): add preliminary support for
2380 supporting a limited set of temporary registers,
2382 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2384 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
2385 genDataPointerSet): ensure assignments always copy in MSB to LSB
2387 (loadRegFromAop): recognize CLRH optimization,
2388 (genFunction): optimize RECEIVE iCodes in reentrant functions
2390 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2392 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

5301 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
5303 * src/SDCCast.c: added an additional type flow in decorateType() of
5304 opposite direction, see feature request #860006; it's enabled at runtime
5305 by setting the environment variable SDCC_NEWTYPEFLOW
5306 * src/SDCCast.h: changed prototype of decorateType()
5307 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
5308 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from

5342 code / RAM are in the same page / bank. This means the linker can
5343 safely allocate code/RAM of separate ASM files to different pages/banks.
5344 * doc/sdccman.lyx: added Slade's tips
5345 * src/mcs51/peeph.def: fixed bug #880768

5387 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
5389 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
5390 loaded with the linker search paths (-L arguments) and the libraries
5391 to be linked with the current source (-l arguments). Changes
5392 currently will affect only the pic16 port.
5393 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5394 include path the port specific paths and port specific libraries,
5395 * gplink command now contains the $3 argument,
5396 * src/pic16/device.h,
5397 * src/pic16/device.c,: structure PIC_device is made public and
5398 renamed to PIC16_device, the same for variable Pics which is renamed

5413 Documenting changes from previous commits.
5414 * configure.in (version 1.56),
5415 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5416 when generating output files to configure the pic16 library,
5417 but now I've commented it out, since gputils aren't installed in the
5418 SF compile farm, so library won't compile
5420 * device/lib/Makefile.in (version 1.56): initially I've added in
5421 target 'all' the prerequestive 'model-pic16' so it compiled the
5422 pic16 library, but now I've commented it out for the same reasons
5424 * added targets 'model-pic16' and 'objects-pic16' to compile the
5426 * added target 'port-specific-objects-pic16' to handle the
5427 generated libraries and copy them into the build/ directory
5428 * added target 'clean-intermediate-pic16' to clean intermediate
5429 files into pic16 directory
5430 * in target 'installdirs' added line to create directory pic16 in
5431 the installation path

5434 added lines to copy all header files to installation path,
5435 * in target 'installdirs' added line create directory for pic16
5436 headers in the installation path

5452 option so that it actually works. Made it specific to the z80, since
5453 the gbz80 doesn't have these kinds of I/O ports.
5455 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5457 * device/include/z180.h,

5481 via literal number. The symbol is placed in the corresponding
5482 position of the data ram
5483 * (pic16_dump_section): relocatable and absolute uninitialized
5484 data are now emitted in sorted order to reduce section naming,
5485 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
5486 weren't marked as being in the access bank,
5488 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5490 Added portion of GNU PIC Library under the directory
5491 device/include/pic16 and device/lib/pic16. These files
5492 contain the declarations of SFRs for the PIC18Fxx2 devices.
5493 The directory is initialized via configure from toplevel.

5725 added variable stackPos,
5727 * gen.c: genCall, assignResultValue: added support for
5728 pushing/retrieving function parameters to/from stack,

5737 pic16emitRegularMap: is modified to properly handle relocatable
5738 symbols under the new scheme,

5744 because gplink yet does not support stack and SDCC does not
5745 yet support a type of crt0.o object to create the final binary.
5747 * Removed many lines that contain 8051 legacy code.
5748 * The code is finally placed under a 'code' directive.
5749 * Added port specific options.
5751 * _process_pragma: simplified since now we do not need *special*
5752 include file to define SFR registers. But a separate header
5753 will be needed. This will be developed later.
5754 * _pic16_parseOptions: added, parses port specific options:
5755 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5756 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5757 --preplace-udata-with=
5759 * _pic16_setDefaultOptions: modified to initialize section names,
5760 but hack is temporarly out of order since it needs improvement.
5761 * _pic16_genAssemblerPreamble: configuration words are emitted by
5762 their address instead of their name. This part is incomplete and
5763 supports only the 18Fxx2 devices. Other devices will emit an error
5764 during assembly since they do not contain the same set of config
5766 * _pic16_genIVT: is modified,
5768 * pcode.c: added definitions for some hardware registers that are needed
5770 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5771 All PCI entries are updated. Now LFSR is supported.
5772 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5773 * added pic16_newpCodeOpLit2 to support instructions with
5774 two literal arguments
5775 * pic16_pCode2str: corrected code that emits assembler instructions
5776 with two literal operands and those that have an access bit modifier
5777 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5778 this fixes a bug which caused some labels to be lost, when an
5779 assembler directive was added, i.e. banksel,
5780 * pic16_FixRegisterBanking: improved logic that causes the insertion
5782 * InlineFunction: functions that are called once, are not any more
5783 inlined. This can be a port option in the future,
5785 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5787 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5788 hold the corresponding uninitialized symbols,
5789 * pic16_allocProcessorRegister: registers have explicit marked the
5791 * pic16_allocInternalRegister: registers are explicit marked as
5793 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5794 processing list, so bit registers were lost,
5797 * ralloc.h: added field 'accessBank' and original symbol operand
5798 in register definition,
5799 * removed the field isMapped from register definition,
5801 ** Several functions have been removed from various sources:
5802 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5803 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5804 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5805 pic16_assignRelocatableRegisters
5807 ** others have been introduced:
5808 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5809 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5811 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5813 * support/scripts/inc2h.pl: changed definition of BIT_AT
5814 to emit 'sbit at' instead of 'bit at'. This was a request.
5816 PIC16 port related preliminary changes:
5817 * gen.c: prefixed function popRegFromString with
5818 pic16_ and all references to it corrected
5819 * pcode.c: all pic16_pc_* hardware registers prefixed
5820 with underscore (_),
5821 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5822 * ralloc.c: newReg(): when register is REG_SFR then
5823 set address to rIdx,
5824 pic16_allocProcessorRegister(): marks register wasUsed=0
5825 pic16_writeUsedRegs(): added a call to assign processor
5826 registers via pic16_assignFixedRegisters
5828 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5830 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5831 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5832 variables in unused register banks. Also the SSEG is placed
5833 wherever there is enough space for it, and IDATA can be anywhere
5834 in internal RAM. For now compile using -Wl-Y[stack_size].
5835 The mem file is different for this option as well, since it
5836 makes no sense of talking about DSEG lenght.
5838 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5840 * src/SDCClrange.c: fixed bug 869095 that caused segfault
5841 in certain cases, e.g. when ROM assignment, patch provided
5842 from Albert den Haan.

6083 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6085 * src/SDCCast.c (decorateType): disabled a transformation I added in
6086 revision 1.188 (access to fields of a structure at an absolute address);
6087 it breaks with bitfields, extern declarations, and gcse analysis.
6088 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
6089 could be assigned through a pointer, so don't complain.
6090 * src/SDCCast.c (astErrors),
6092 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

6194 * src/mcs51/main.c: started fixing bug #737001 (SDCC not clearing
6195 uninitialized variables) for the mcs51. Set environment variable
6196 SDCC_GENRAMCLEAR to test.
6197 xdata initialization slightly shorter
6199 2003-11-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6846 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
6847 fetching of the pointer
6848 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
6849 copied from genNearPointerSet()
6850 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
6851 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

6867 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6868 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
6869 type for bits was changed. It resulted in bit variables becoming
6870 global, which is not permitted in PIC 14 assembly output.
6872 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

6887 A few small changes that speed up the peephole optimizer.
6891 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6893 Try to make the peephole optimizer smarter by maintaining
6894 an association between the assembly source code and the
6895 iCodes that originated them. Put this information to use
6896 with a new peephole rule condition "notVolatile" so that
6897 the rules can be aggressive yet still safe.
6902 * src/mcs51/peeph.def
6904 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6908 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
6909 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6910 if the left or right operand symbols have the accuse flag set.
6912 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6914 Changed the type of the result of the ! (NOT) operator to char;
6915 previously it returned the same type as the source. This allows
6916 us to eliminate all the genFloatNot functions (all of its target
6917 implementations were very buggy) since !float can use the same

6929 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6930 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6931 during interrupts. Ensure WSAVE is located at a shared bank address.
6932 2. Fixed page selection in some places
6933 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6934 the registers name strings.
6935 4. Fixed "signed / unsigned compare" compiler warnings.
6936 5. The PIC port manages its own allocation of the general purpose
6937 registers, but makes no attempt to reuse them. As a result when
6938 compiling it soon runs out of general purpose registers. Some
6939 additional code was added to the files pcode.c and device.c to walk
6940 through the function call tree and rename the registers so that they
6950 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

6957 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6959 Made bitfield a distinct type from bit so that bitfields
6960 convert as per ANSI C and bits retain their traditional
6961 boolean style behaviour. Implemented bitfield support in
6969 * src/ds390/gen.c: bit v bitfield split
6970 * src/z80/gen.c: New support for bitfields
6971 * support/regression/tests/bitfields.c: reenabled z80,
6974 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6976 Rules 246.x, 247.x relate to bitfields, the others speed up
6977 access to xdata mapped I/O devices.
6979 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6981 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6983 Cleaned up genPackBits and genUnpackBits and added two helper
6984 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6985 for literal assignments in genPackBits (thanks to Frieder for
6991 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6993 Fixed bug #748310 (pointer to function type mishandled when the
6994 function name is omitted). Also fixed a SIGSEGV when a function
6995 attribute (reentrant, etc) is used on a non-function or on a
6996 function but misplaced before the parameter list.
6998 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed

7023 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7025 Made the constant following the "interrupt" keyword optional. If
7026 omitted, the function will not automatically be given an entry
7027 in the interrupt vector table (similar to #pragma NOIV, but
7028 less syntacticly kludgy). The interrupt number is also now
7029 range checked. Also fixed a bug in the high order bit example

7043 * src/SDCCicode.c (operandOperation): rewritten some ops
7044 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
7045 * src/SDCCsymt.c (computeType): literals are handled the same way as any
7047 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
7048 be re-activated by defining REDUCE_LITERALS)

7558 * src/SDCCmain.c: linkOptions is changed to set *,
7559 added if/endif conditional macros to remove options help
7560 messages from optionsTable when a port is not configured, added
7561 support for the PIc16 port in the ports table, when executing
7562 the compiler with no port specified on command line, a default
7563 port is selected with the new macro DEFAULT_PORT which is
7564 defined in port.h, in setDefaultOptions() linkOptions is removed
7565 from initialization assignment, since now it is a set,
7566 parseCmdLine uses setParseWithComma for linkOptions, in
7567 linkEdit() linkOptions are accessed with new function indexSet()
7568 which returns the i'th item of a set variable. See SDCCset.c, in
7569 linkEdit() when calling buildCmdLine(), added linkOptions as
7570 last argument. Now users can pass arguments to gplink via the
7571 -Wl option, main() uses pic16glue() to glue up pic16 programs

7583 * src/pic16/glue.c: commented out some error producing lines
7584 * src/pic16/main.c: __config directives are commented out to stop
7585 gpasm complaining and test the linkage with gplink, _linkCmd and
7586 _asmCmd changed to be more gplink and gpasm friendly
7587 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7588 produced an error when parsed, peep rule 12 is added to utilize
7589 movff, but it is commented out since the pCode does not support
7590 yet a command with 2 address arguments
7592 2003-05-18 <johan AT balder>
7594 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7621 2003-05-11 Borut Razem <borut.razem AT siol.net>
7623 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
7624 the path of bin directory, so that PATH is the only env. variable, which has to be set
7625 in case of standard installation.
7626 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

8663 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8664 .adb instead of .cdb
8666 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8668 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8669 value from option --iram-size.
8671 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8673 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8676 2002-09-18 <wiml AT hhhh.org>
8678 * SDCClrange.h: exposed setFromRange() and setToRange()
8679 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8680 packRegsForAccUse() (bug 542397)
8681 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8682 multiple times and emitting the fetch operations more than once
8683 added aopGetUsesAcc() function to allow binary operators to
8684 fetch their operands in the correct order; made genMinus() emit
8685 compact code for X = LITERAL - Y
8687 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8688 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8689 sprintf() in line 1267.
8691 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8692 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8695 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8696 Changes to aslink (All the changes are marked with 'JCF'):
8698 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8701 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8702 area BSEG. Also moves, if possible, the DATA area down into the internal
8703 ram so more space is available.
8705 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8708 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8709 not bytes. Function summary() which creates a memory usage summary
8710 file with extension .mem. Reports of overlaping stack and small stack
8711 size. If the space for the stack is less than 16 bytes aslink trows a
8714 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8715 the 8051. Option 'y' for memory summary output file.
8717 Changes to sdcc (All the changes are marked with 'JCF'):
8719 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8721 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8722 overlaying area for it (uses RegBankUsed[4]).
8724 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8725 bank zero as used by default. By default aslink locates the stack
8726 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8727 the creation of the .mem file. Delegates the allocation of data area
8728 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8729 the begining of the stack area to aslink.
8731 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8732 glue() in SDCCglue.c creates an area for it.
8734 2002-09-03 Borut Razem <borut.razem AT siol.net>
8735 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8736 sdcc/src/pic/glue.c:
8737 introduced atexit() handler for teporay files removal in case of
8738 errors, assertions, ...
8740 2002-08-29 Borut Razem <borut.razem AT siol.net>
8741 * sdcc/support/cpp2/auto-host_vc_in.h:
8742 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8743 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8744 Maybe there is a similar problem with BORLANDC? It should be checked!
8746 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8747 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8748 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8749 was not executed, and the compiler (cl) launched a warning:
8750 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8752 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8753 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8755 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8756 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8758 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8759 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8760 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8761 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8762 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8763 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8764 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8765 - added Release configuration in VS projects
8766 - review of compiler an linker options
8767 - VC .exe files are generated in bin_vc directory, not to interfere
8768 with binaries generated from other projects (cygwin, mingw, bcc ...)
8770 * sdcc/src/yacc.dsp: added
8772 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8773 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8774 and insert the version number definitions from .version
8776 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8778 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8779 added - genarate auto-host.h using auto-host_vc_in.h as template
8782 removed from CVS, generated automatically
8784 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8785 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8787 2002-08-11 Borut Razem <borut.razem AT siol.net>
8788 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8790 2002-08-10 Borut Razem <borut.razem AT siol.net>
8791 * src/SDCCmain.c (main):
8792 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8793 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8794 The consequence was that some temporary files were not removed.
8797 unification of code in functions tempfilename() and tempfile():
8798 function tempnam() is defined in Visual Studio 6.0 and .NET
8800 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8802 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8803 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8804 - removed compiler command line option /WX: Treats all warnings as errors
8805 - update a list of source files, included into the project
8807 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8808 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
8809 changed project type to Generic Project so that can be correcly converted to VS.NET project
8811 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
8813 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
8815 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
8817 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
8818 added return 0 statements after assert() to make compiler happy
8820 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
8821 added newline in the def file to keep MSC compiler satisfied
8823 * sdcc/src/z80/gen.c:
8824 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
8825 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
8826 - solved MSC error in function aopDump()
8828 * sdcc_vc.h: define PREFIX as "\\sdcc"
8830 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
8831 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

8870 2002-03-28 Johan Knol <johan AT balder>
8872 * src/SDCCval.c: fixed bug #532436
8874 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8876 Added "char *Processor" field to the port structure.
8879 Added -p option. Allows port dependent processor to be specified.
8882 Initialized the new field char *Processor field to NULL in all ports
8885 Compiler generated registers for interrupt context saving
8886 were not getting allocated.
8888 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
8891 Fixed left shift. Will promote the left side of a left shift
8892 if a) left shifting more than size of operand or b) when assigned
8893 to something size > size of left side
8895 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8897 tons of changes. Register allocation has been
8898 rewritten. Added customization for the various PICs. Flow

9003 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
9005 * sdcc/src/SDCCloop.c:
9006 Previous fix was not good. basic blocks that have "break" or "return" are
9007 not really partof a loop , but live ranges used in these blocks should
9008 be live thru the entire loop, so set partOfLoop but don't add them to
9011 2002-02-21 <johan AT FRIJA>
9013 * src/SDCCcse.c: fixed bug #514308
9015 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>

9019 statement inside a loop, it was not being considered part of the loop.
9021 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
9023 2002-02-10 Karl Bongers <karl AT turbobit.com>
9026 Fixed up SDCDB debugger somewhat. Updated debugger/README
9027 with lots of comments and notes.
9029 * device/examples/test2.c:
9030 Fix bug, "red" variable not being initialized(compiler complained).
9032 * device/examples/Makefile, examples/test3.c:

9034 for use as a multiple module SDCDB test case.
9036 * sim/ucsim/cmd.src/cmdset.cc:
9037 Took out debug printfs in ucsim "next" command.
9040 Karl and Johan start ucsim XA support. Most dissassembly working,

9081 set preprocessor defines (depending on options)
9083 * src/SDCCicode.c, src/SDCCicode.h:
9084 changes made to handle multiple sends & receives
9087 Added options --protect-sp-update (ds390) and --parms-in-bank1 (ds390/mcs51)
