1792 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1794 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1795 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1797 One basic decision: e.g. src/clean.mk includes further files. In order
1798 to make this work there are two solutions:
1799 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1800 run configure on them. This way they can use
1801 'include $(srcdir)/port-clean.mk'
1802 - always include clean.mk by the Makefile at the same level. To avoid
1803 that `make clean` tries to include and build Makefile.dep the
1804 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1805 implemented, because now even `make uninstall` doesn't create
1806 Makefile.in. clean.mk could be eliminated by pasting it in
1809 * debugger/mcs51/Makefile.in: build own objects from library sources
1810 (SLIB, SDCC) in current directory
1812 * configure, configure.in: renamed --disable-device-lib-build in
1813 --disable-device-lib; added --enable-doc, the required tools are
1814 searched by configure; added result message; the toolchain for the
1815 belonging ports are now only built, if the port is enabled.
1817 * support/regression/*: all output is written in directory gen, because
1818 the fwk and ports directories don't livet in the build tree using vpath
1820 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1821 --disable-device-lib, added --enable-doc, added section VPATH
1823 * sim/ucsim/configure.in,
1824 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1825 z80 are enabled by default
1827 2006-04-24 Raphael Neider <rneider AT web.de>
1829 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1830 to config word, "pic14_"-prefixed some extern functions
1831 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1832 config word has been found
1833 * src/pic/device.h: added prototypes
1834 * src/pic/pcode.c: added "pic14_"-prefix where needed

2142 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
2143 call to allocReg, not by manually allocating a new one,
2144 (pic16_assignRegisters): now before going through the register
2145 allocating functions mark all registers as free. This eliminates some
2146 side effects resulting from peephole parser done earlier in the backbone

2208 the number of the local variables used by the specified function, added
2209 'xinst' for initial support for Extended Instruction Support,
2210 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
2211 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
2212 port->fun_prefix anymore (may change later),
2213 (genFunction, genEndFunction): do not store/restore local registers for
2214 _main (this should take care the --main-return command line option in
2216 (genOr): removed some legacy pic-port instructions,
2217 * src/pic16/genarith.c (genAddLit): re-enabled old code because
2218 performing operations with SFR's causes data to be written more than
2219 once to each SFR. Perhaps SFRs should be handled in special cases...
2220 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
2222 * src/pic16/main.c (_process_pragma): stack bound checking did not take
2223 into account for stack starting position,
2224 (struct OPTIONS pic16_optionsTable): added command line argument
2225 --extended or -y for Extended Instruction Support,
2226 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
2227 (deassignLRs): *** perhaps the most important change, old 'for' code
2228 (commented out for reference), didn't account for some registers which
2229 were left marked 'not free' after a pointer operation. The change
2230 reduces register usage a lot in some cases

4505 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
4506 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
4507 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
4508 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
4509 always available in leading double underscore form. The C99 support is
4510 mostly missing, but it's a start.

4590 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
4592 * device/lib/printf_large.c: removed inline assembly for portability and
4593 readability. Use printf_fast if speed or size are more important.
4594 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4595 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4597 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4599 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4600 prevent compiler warning
4602 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4604 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4605 moved to level 0 and declared as static. Also they are explicit
4606 placed in access bank. This was necessery because some times they
4607 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4608 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4609 optimizations. Currently only compare to unsigned char is implemented,
4610 * src/pic16/gen.c: added fReturnIdx array,
4611 * (struct resolvedIfx) is moved to gen.h and made public,
4612 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4613 * (aopForSym): added an optimization to directly store in stack of
4614 the operand of a SEND iCode,
4615 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4616 but as registers instead (AOP_REG) using the fReturnIdx array,
4617 * (pic16_freeAsmop): remove the freed register from the
4618 _G.sregsAlloc field,
4619 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4620 a compare of 'WREG',
4621 * (pic16_popGetTempRegCond): changed function prototype, now
4622 function takes also a bitVector argument v which holds the current
4623 set of registers that are allocated for stack access by aopForSym,
4624 registers allocated in aopForSym for accessing stack symbols are not
4625 any more part of the functions usedRegs field,
4626 * (genCall): some times aopOp is called for a stack variable to be
4627 send, aopForSym might perform the push, if this is true make sure
4628 that genCall doesn't push the variable twice by testing _G.resDirect,
4629 * (genFunction): changed testing for unspecified interrupt number
4630 from 256 to INTNO_UNSPEC,
4631 * modified selection scheme of frame pointer generation. Previously
4632 if function did use local registers a frame pointer was generated,
4633 now a frame pointer is generated only if function has arguments
4634 (that need PLUSW2 register access), or has stack arguments, or the
4635 compiler is not instructed to omit the frame pointer,
4636 * (genEndFunction): before restoring local registers that were saved
4637 in the function preamble, also restore the registers that *might*
4638 have been allocated for stack access,
4639 * (genRet): removed some old comments,
4640 * (genCmp, the active (RN's) version): added a call to the
4641 pic16_genCmp_special function to perform the compare with a more
4642 robust and optimized way,
4643 * (genInline): a feature has been added in inline code generation,
4644 which allows a wildcard variable substitution when writing inline
4645 assembly. Code is incomplete and experimental therefore undocumented,
4646 * (genCast): changed order of aopOp for result and right to allow
4647 aopForSym to directly load the result if possible,
4648 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4649 perform an optimized compare on some selected special occasions,
4650 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4651 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4652 generate an IVT any more,
4653 * src/pic16/main.c (pic16_optionsTable): added command line option
4655 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4656 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4658 * src/pic16/NOTES: Raphael Neider added in list of active developers
4659 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4660 jumptable_end to prevent bug #,
4661 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4662 inCond and outCond fields,
4663 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4664 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4665 turn off register spilling,
4666 * (packRegsForOneUse): synced with other ports' versions although it
4667 is not used currently,
4668 * (pic16_packRegisters): added an optimization while reading
4669 structure bitfields, some registers may be saved (malloc code is
4670 decreased by 80 bytes)
4672 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4674 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4675 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4676 this can be optimized more?
4678 2005-03-10 Raphael Neider <rneider AT web.de>
4680 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4681 genNearPointerGet): (hopefully) fixed access to bitfields via
4682 pointers (p->bitN = x; and x = p->bitN; failed)
4684 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

4727 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
4728 to keep the correct label reference count when adding/removing references
4729 to labels. A peephole file using this is appended to patch #1144962.
4731 2005-02-14 Raphael Neider <rneider AT web.de>

5316 Adding support for replacing ljmps with sjmps in jumptables
5317 generated for switch statements. For now you need to set the
5318 environment variable SDCC_SJMP_JUMPTABLE to enable this.
5319 Now 4 algorithms for mcs51 jumptable generation are used:
5320 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
5321 addresses loaded pc-relative for up to 112 cases and stack-pushing
5322 target addresses loaded with offset from dptr for up to 256 cases.

5352 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
5354 * added libc directory. The current version of LibC contains string
5355 functions, ctype functions and macros and some functions of the
5356 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
5357 be extensively tested in the future. Standard disclaimer here.
5358 Library is not automatically build yet. But one can build it by
5359 invoking 'make' inside the libc directory.

5370 * (pic16_storeForReturn): optimized return of 0,
5371 * (genCmp): experimental code for new genCmp which uses PIC18's
5372 special compare&skip instructions. Initial tests fail some times
5373 with variables grater than 1 byte in size, so new code is disabled,
5374 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5376 * (genCast): began a fix to optimize the casting of a bit to another
5377 bit, now assigning a bitfield to another bitfield will fail, sorry,
5378 * src/pic16/main.c: disabled the use of lr-support feature,
5379 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

5385 * (isBankInstruction): modified to return 0 for no banking instruction,
5386 and 1 for banking instruction,
5387 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
5388 caused stop processing pCodes after a inline assembly block,
5389 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
5390 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
5391 registers when it shouldn't,
5392 * src/pic16/ralloc.c (allocReg): add preliminary support for
5393 supporting a limited set of temporary registers,
5395 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5397 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
5398 genDataPointerSet): ensure assignments always copy in MSB to LSB
5400 (loadRegFromAop): recognize CLRH optimization,
5401 (genFunction): optimize RECEIVE iCodes in reentrant functions
5403 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5405 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

8314 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
8316 * src/SDCCast.c: added an additional type flow in decorateType() of
8317 opposite direction, see feature request #860006; it's enabled at runtime
8318 by setting the environment variable SDCC_NEWTYPEFLOW
8319 * src/SDCCast.h: changed prototype of decorateType()
8320 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
8321 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from

8353 added support for multiple code pages and multiple RAM banks on the
8354 PIC 14 port. The ASM files now no longer simply assume all the
8355 code / RAM are in the same page / bank. This means the linker can
8356 safely allocate code/RAM of separate ASM files to different pages/banks.
8357 * doc/sdccman.lyx: added Slade's tips
8358 * src/mcs51/peeph.def: fixed bug #880768

8400 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
8402 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
8403 loaded with the linker search paths (-L arguments) and the libraries
8404 to be linked with the current source (-l arguments). Changes
8405 currently will affect only the pic16 port.
8406 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8407 include path the port specific paths and port specific libraries,
8408 * gplink command now contains the $3 argument,
8409 * src/pic16/device.h,
8410 * src/pic16/device.c,: structure PIC_device is made public and
8411 renamed to PIC16_device, the same for variable Pics which is renamed

8426 Documenting changes from previous commits.
8427 * configure.in (version 1.56),
8428 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8429 when generating output files to configure the pic16 library,
8430 but now I've commented it out, since gputils aren't installed in the
8431 SF compile farm, so library won't compile
8433 * device/lib/Makefile.in (version 1.56): initially I've added in
8434 target 'all' the prerequestive 'model-pic16' so it compiled the
8435 pic16 library, but now I've commented it out for the same reasons
8437 * added targets 'model-pic16' and 'objects-pic16' to compile the
8439 * added target 'port-specific-objects-pic16' to handle the
8440 generated libraries and copy them into the build/ directory
8441 * added target 'clean-intermediate-pic16' to clean intermediate
8442 files into pic16 directory
8443 * in target 'installdirs' added line to create directory pic16 in
8444 the installation path

8447 added lines to copy all header files to installation path,
8448 * in target 'installdirs' added line create directory for pic16
8449 headers in the installation path

8465 option so that it actually works. Made it specific to the z80, since
8466 the gbz80 doesn't have these kinds of I/O ports.
8468 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8470 * device/include/z180.h,

8497 data are now emitted in sorted order to reduce section naming,
8498 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
8499 weren't marked as being in the access bank,
8501 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
8503 Added portion of GNU PIC Library under the directory
8504 device/include/pic16 and device/lib/pic16. These files
8505 contain the declarations of SFRs for the PIC18Fxx2 devices.

8750 pic16emitRegularMap: is modified to properly handle relocatable
8751 symbols under the new scheme,

8757 because gplink yet does not support stack and SDCC does not
8758 yet support a type of crt0.o object to create the final binary.
8760 * Removed many lines that contain 8051 legacy code.
8761 * The code is finally placed under a 'code' directive.
8762 * Added port specific options.
8764 * _process_pragma: simplified since now we do not need *special*
8765 include file to define SFR registers. But a separate header
8766 will be needed. This will be developed later.
8767 * _pic16_parseOptions: added, parses port specific options:
8768 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8769 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8770 --preplace-udata-with=
8772 * _pic16_setDefaultOptions: modified to initialize section names,
8773 but hack is temporarly out of order since it needs improvement.
8774 * _pic16_genAssemblerPreamble: configuration words are emitted by
8775 their address instead of their name. This part is incomplete and
8776 supports only the 18Fxx2 devices. Other devices will emit an error
8777 during assembly since they do not contain the same set of config
8779 * _pic16_genIVT: is modified,
8781 * pcode.c: added definitions for some hardware registers that are needed
8783 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8784 All PCI entries are updated. Now LFSR is supported.
8785 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8786 * added pic16_newpCodeOpLit2 to support instructions with
8787 two literal arguments
8788 * pic16_pCode2str: corrected code that emits assembler instructions
8789 with two literal operands and those that have an access bit modifier
8790 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8791 this fixes a bug which caused some labels to be lost, when an
8792 assembler directive was added, i.e. banksel,
8793 * pic16_FixRegisterBanking: improved logic that causes the insertion
8795 * InlineFunction: functions that are called once, are not any more
8796 inlined. This can be a port option in the future,
8798 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8800 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8801 hold the corresponding uninitialized symbols,
8802 * pic16_allocProcessorRegister: registers have explicit marked the
8804 * pic16_allocInternalRegister: registers are explicit marked as
8806 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8807 processing list, so bit registers were lost,
8810 * ralloc.h: added field 'accessBank' and original symbol operand
8811 in register definition,
8812 * removed the field isMapped from register definition,
8814 ** Several functions have been removed from various sources:
8815 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8816 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8817 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8818 pic16_assignRelocatableRegisters
8820 ** others have been introduced:
8821 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8822 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8824 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8826 * support/scripts/inc2h.pl: changed definition of BIT_AT
8827 to emit 'sbit at' instead of 'bit at'. This was a request.
8829 PIC16 port related preliminary changes:
8830 * gen.c: prefixed function popRegFromString with
8831 pic16_ and all references to it corrected
8832 * pcode.c: all pic16_pc_* hardware registers prefixed
8833 with underscore (_),
8834 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8835 * ralloc.c: newReg(): when register is REG_SFR then
8836 set address to rIdx,
8837 pic16_allocProcessorRegister(): marks register wasUsed=0
8838 pic16_writeUsedRegs(): added a call to assign processor
8839 registers via pic16_assignFixedRegisters
8841 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8843 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8844 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8845 variables in unused register banks. Also the SSEG is placed
8846 wherever there is enough space for it, and IDATA can be anywhere
8847 in internal RAM. For now compile using -Wl-Y[stack_size].
8848 The mem file is different for this option as well, since it
8849 makes no sense of talking about DSEG lenght.
8851 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8853 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8854 in certain cases, e.g. when ROM assignment, patch provided
8855 from Albert den Haan.

9098 * src/SDCCast.c (decorateType): disabled a transformation I added in
9099 revision 1.188 (access to fields of a structure at an absolute address);
9100 it breaks with bitfields, extern declarations, and gcse analysis.
9101 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
9102 could be assigned through a pointer, so don't complain.
9103 * src/SDCCast.c (astErrors),
9105 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

9210 xdata initialization slightly shorter
9212 2003-11-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9861 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
9862 copied from genNearPointerSet()
9863 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
9864 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

9880 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9881 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9882 type for bits was changed. It resulted in bit variables becoming
9883 global, which is not permitted in PIC 14 assembly output.

9900 A few small changes that speed up the peephole optimizer.
9904 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9906 Try to make the peephole optimizer smarter by maintaining
9907 an association between the assembly source code and the
9908 iCodes that originated them. Put this information to use
9909 with a new peephole rule condition "notVolatile" so that
9910 the rules can be aggressive yet still safe.
9915 * src/mcs51/peeph.def
9917 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9921 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9922 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9923 if the left or right operand symbols have the accuse flag set.
9925 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9927 Changed the type of the result of the ! (NOT) operator to char;
9928 previously it returned the same type as the source. This allows
9929 us to eliminate all the genFloatNot functions (all of its target
9930 implementations were very buggy) since !float can use the same

9942 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9943 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9944 during interrupts. Ensure WSAVE is located at a shared bank address.
9945 2. Fixed page selection in some places
9946 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9947 the registers name strings.
9948 4. Fixed "signed / unsigned compare" compiler warnings.
9949 5. The PIC port manages its own allocation of the general purpose
9950 registers, but makes no attempt to reuse them. As a result when
9951 compiling it soon runs out of general purpose registers. Some
9952 additional code was added to the files pcode.c and device.c to walk
9953 through the function call tree and rename the registers so that they
9963 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9964 genPlus() & genMinus() when the result is the same as left or right

9970 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9972 Made bitfield a distinct type from bit so that bitfields
9973 convert as per ANSI C and bits retain their traditional
9974 boolean style behaviour. Implemented bitfield support in
9982 * src/ds390/gen.c: bit v bitfield split
9983 * src/z80/gen.c: New support for bitfields
9984 * support/regression/tests/bitfields.c: reenabled z80,
9987 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9989 Rules 246.x, 247.x relate to bitfields, the others speed up
9990 access to xdata mapped I/O devices.
9992 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9994 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9996 Cleaned up genPackBits and genUnpackBits and added two helper
9997 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9998 for literal assignments in genPackBits (thanks to Frieder for
10004 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10006 Fixed bug #748310 (pointer to function type mishandled when the
10007 function name is omitted). Also fixed a SIGSEGV when a function
10008 attribute (reentrant, etc) is used on a non-function or on a
10009 function but misplaced before the parameter list.
10011 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
10013 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
10014 * support/Util/SDCCerr.h,

10036 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10038 Made the constant following the "interrupt" keyword optional. If
10039 omitted, the function will not automatically be given an entry
10040 in the interrupt vector table (similar to #pragma NOIV, but
10041 less syntacticly kludgy). The interrupt number is also now
10042 range checked. Also fixed a bug in the high order bit example

10058 * src/SDCCsymt.c (computeType): literals are handled the same way as any
10060 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
10061 be re-activated by defining REDUCE_LITERALS)
10062 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
10063 unsigned, but are signed by default
10064 * src/SDCCval.c (constVal): rearranged
10065 * src/SDCCval.c (valMod): preliminary fix

10573 messages from optionsTable when a port is not configured, added
10574 support for the PIc16 port in the ports table, when executing
10575 the compiler with no port specified on command line, a default
10576 port is selected with the new macro DEFAULT_PORT which is
10577 defined in port.h, in setDefaultOptions() linkOptions is removed
10578 from initialization assignment, since now it is a set,
10579 parseCmdLine uses setParseWithComma for linkOptions, in
10580 linkEdit() linkOptions are accessed with new function indexSet()
10581 which returns the i'th item of a set variable. See SDCCset.c, in
10582 linkEdit() when calling buildCmdLine(), added linkOptions as
10583 last argument. Now users can pass arguments to gplink via the
10584 -Wl option, main() uses pic16glue() to glue up pic16 programs

10598 gpasm complaining and test the linkage with gplink, _linkCmd and
10599 _asmCmd changed to be more gplink and gpasm friendly
10600 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10601 produced an error when parsed, peep rule 12 is added to utilize
10602 movff, but it is commented out since the pCode does not support
10603 yet a command with 2 address arguments

11625 2003-01-07 <johan AT balder>
11627 * src/SDCCast.c (decorateType): fixed bug #600035
11629 2003-01-07 Bernhard Held <bernhard AT bernhardheld.de>
11630 * as/mcs51/lkmem.c: added several l-modifiers to printf to remove warnings
11631 * as/mcs51/lkaomf51.c: #include <ctype.h> to remove warnings
11632 * src/pic/main.c (_hasNativeMulFor): outcommented unused variables to remove warnings
11633 * src/pic/pcode.c: outcommented unused variable to remove warnings

11640 2003-01-06 <johan AT balder>
11642 * src/SDCCicode.c: fixed array add
11644 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
11645 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
11646 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
11648 2003-01-04 <johan AT balder>
11650 * src/SDCCval.c (getNelements): fixed the initialized array of structures
11652 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11653 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
11655 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
11656 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
11657 * support/regression/tests/bug-524697.c: fit mem usage into 8032
11659 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
11660 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
11662 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
11663 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
11665 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
11666 * src/mcs51/main.c: removed {bindir}{sep} from aslink
11668 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11670 * in /sdcc/as/mcs51/ changed these files in order to create an
11671 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11672 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11673 following files to include the previous two files: aslink.dsp,
11674 Makefile.aslink, Makefile.bcc, and Makefile.in.
11676 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11677 .adb instead of .cdb
11679 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11681 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11682 value from option --iram-size.
11684 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11686 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11689 2002-09-18 <wiml AT hhhh.org>
11691 * SDCClrange.h: exposed setFromRange() and setToRange()
11692 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11693 packRegsForAccUse() (bug 542397)
11694 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11695 multiple times and emitting the fetch operations more than once
11696 added aopGetUsesAcc() function to allow binary operators to
11697 fetch their operands in the correct order; made genMinus() emit
11698 compact code for X = LITERAL - Y
11700 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11701 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11702 sprintf() in line 1267.
11704 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11705 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11708 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11709 Changes to aslink (All the changes are marked with 'JCF'):
11711 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11714 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11715 area BSEG. Also moves, if possible, the DATA area down into the internal
11716 ram so more space is available.
11718 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11721 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11722 not bytes. Function summary() which creates a memory usage summary
11723 file with extension .mem. Reports of overlaping stack and small stack
11724 size. If the space for the stack is less than 16 bytes aslink trows a
11727 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11728 the 8051. Option 'y' for memory summary output file.
11730 Changes to sdcc (All the changes are marked with 'JCF'):
11732 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11734 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11735 overlaying area for it (uses RegBankUsed[4]).
11737 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11738 bank zero as used by default. By default aslink locates the stack
11739 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11740 the creation of the .mem file. Delegates the allocation of data area
11741 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11742 the begining of the stack area to aslink.
11744 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11745 glue() in SDCCglue.c creates an area for it.
11747 2002-09-03 Borut Razem <borut.razem AT siol.net>
11748 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11749 sdcc/src/pic/glue.c:
11750 introduced atexit() handler for teporay files removal in case of
11751 errors, assertions, ...
11753 2002-08-29 Borut Razem <borut.razem AT siol.net>
11754 * sdcc/support/cpp2/auto-host_vc_in.h:
11755 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11756 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11757 Maybe there is a similar problem with BORLANDC? It should be checked!
11759 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11760 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11761 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11762 was not executed, and the compiler (cl) launched a warning:
11763 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11765 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11766 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11768 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11769 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11771 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11772 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11773 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11774 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11775 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11776 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11777 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11778 - added Release configuration in VS projects
11779 - review of compiler an linker options
11780 - VC .exe files are generated in bin_vc directory, not to interfere
11781 with binaries generated from other projects (cygwin, mingw, bcc ...)
11783 * sdcc/src/yacc.dsp: added
11785 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11786 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11787 and insert the version number definitions from .version
11789 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11791 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11792 added - genarate auto-host.h using auto-host_vc_in.h as template
11795 removed from CVS, generated automatically
11797 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11798 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11800 2002-08-11 Borut Razem <borut.razem AT siol.net>
11801 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11803 2002-08-10 Borut Razem <borut.razem AT siol.net>
11804 * src/SDCCmain.c (main):
11805 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11806 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11807 The consequence was that some temporary files were not removed.
11810 unification of code in functions tempfilename() and tempfile():
11811 function tempnam() is defined in Visual Studio 6.0 and .NET
11813 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11815 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11816 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11817 - removed compiler command line option /WX: Treats all warnings as errors
11818 - update a list of source files, included into the project
11820 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11821 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11822 changed project type to Generic Project so that can be correcly converted to VS.NET project
11824 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11826 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11828 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11830 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11831 added return 0 statements after assert() to make compiler happy
11833 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11834 added newline in the def file to keep MSC compiler satisfied
11836 * sdcc/src/z80/gen.c:
11837 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11838 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11839 - solved MSC error in function aopDump()
11841 * sdcc_vc.h: define PREFIX as "\\sdcc"
11843 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
11844 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

11847 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
11848 - Rewrote the register banking algorithm.
11849 - Added pCode live-range analysis to registers (for now, only non-used and
11850 singly-used registers optimized away)
11852 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
11854 * 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.

11877 * src/z80/main.c: Added force callee saves for jaune.
11879 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
11881 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
11883 2002-03-28 Johan Knol <johan AT balder>
11885 * src/SDCCval.c: fixed bug #532436
11887 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11889 Added "char *Processor" field to the port structure.
11892 Added -p option. Allows port dependent processor to be specified.
11895 Initialized the new field char *Processor field to NULL in all ports
11898 Compiler generated registers for interrupt context saving
11899 were not getting allocated.
11901 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
11904 Fixed left shift. Will promote the left side of a left shift
11905 if a) left shifting more than size of operand or b) when assigned
11906 to something size > size of left side
11908 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11910 tons of changes. Register allocation has been
11911 rewritten. Added customization for the various PICs. Flow
11912 analysis is restructured. ...
11914 * src/pic/device.h:
11917 * src/pic/device.c:
11918 Added. device.c is a PIC port hack to accomodate variations
11921 2002-03-13 Michael Hope <michaelh AT vroom>
11923 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
11925 2002-03-04 johanknol <johanknol AT manik>
11927 * /src/SDCCval.c: fixed
11929 const unsigned char arr[][2] = { { 0, 1 } };

12016 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
12018 * sdcc/src/SDCCloop.c:
12019 Previous fix was not good. basic blocks that have "break" or "return" are
12020 not really partof a loop , but live ranges used in these blocks should
12021 be live thru the entire loop, so set partOfLoop but don't add them to
12024 2002-02-21 <johan AT FRIJA>
12026 * src/SDCCcse.c: fixed bug #514308
12028 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
12031 Fixed BUG #519583. If a conditional block ended in a return/break
12032 statement inside a loop, it was not being considered part of the loop.
12034 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
12036 2002-02-10 Karl Bongers <karl AT turbobit.com>

12047 for use as a multiple module SDCDB test case.
12049 * sim/ucsim/cmd.src/cmdset.cc:
12050 Took out debug printfs in ucsim "next" command.
12052 * sim/ucsim/xa.src:
12053 Karl and Johan start ucsim XA support. Most dissassembly working,
12054 about 75% emulation done(plenty of work remaining).
12056 * sim/ucsim/z80.src:
12057 Add Z80 support to ucsim, add test-ucz80 regression test,
12058 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
12059 Notice z80 compiler fails on examples/test3.c/crc code.
12061 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>
12063 * src/mcs51/gen.c, src/mcs51/main.c, src/mcs51/ralloc.c:
12064 Added support for --parms-in-bank1
