3456 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
3458 Enabled VPATH feature: changed nearly all Makefiles (149 files).
3459 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
3461 One basic decision: e.g. src/clean.mk includes further files. In order
3462 to make this work there are two solutions:
3463 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
3464 run configure on them. This way they can use
3465 'include $(srcdir)/port-clean.mk'
3466 - always include clean.mk by the Makefile at the same level. To avoid
3467 that `make clean` tries to include and build Makefile.dep the
3468 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
3469 implemented, because now even `make uninstall` doesn't create
3470 Makefile.in. clean.mk could be eliminated by pasting it in
3473 * debugger/mcs51/Makefile.in: build own objects from library sources
3474 (SLIB, SDCC) in current directory
3476 * configure, configure.in: renamed --disable-device-lib-build in
3477 --disable-device-lib; added --enable-doc, the required tools are
3478 searched by configure; added result message; the toolchain for the
3479 belonging ports are now only built, if the port is enabled.
3481 * support/regression/*: all output is written in directory gen, because
3482 the fwk and ports directories don't livet in the build tree using vpath
3484 * doc/sdccman.lyx: renamed --disable-device-lib-build to

3739 2006-04-05 Maarten Brock <sourceforge.brock AT dse.nl>
3741 * src/mcs51/gen.c (genCall): fixed bug 1457608
3743 2006-03-30 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

3762 implemented patch 1120823 Thanks to Willy De la Court (normal
3763 interrupts need an interrupt number now if they are made critical),
3764 and enabled nesting of critical functions though not for gbz80
3765 (genCritical, genEndCritical): added functions
3766 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
3767 * src/z80/mappings.i: added "ei" to all mappings

3776 2006-03-16 Raphael Neider <rneider AT web.de>
3778 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
3779 the left operand is shorter than the result (c* = lit-c* + int),
3781 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
3784 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3786 * src/.version: increased version number to 2.5.5
3787 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
3788 linking is done manually in pic16 port's _linkEdit,
3789 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
3790 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
3791 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
3792 allocate asmop as AOP_ACC,
3793 (aopForRemat): added parameter 'bool result' in function declaration,
3794 (pic16_aopGet): return AOP_ACC when accessing WREG,
3795 (pic16_popGetTempReg): minor modification,

3806 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
3807 call to allocReg, not by manually allocating a new one,
3808 (pic16_assignRegisters): now before going through the register
3809 allocating functions mark all registers as free. This eliminates some
3810 side effects resulting from peephole parser done earlier in the backbone
3812 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

3860 * support/regression/tests/array.c: added parenthesis, made arrays unsigned
3862 2006-03-06 Borut Razem <borut.razem AT siol.net>
3864 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
3865 made the linker quiet
3867 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
3869 * src/pic16/gen.c (genPcall): fixed bug #1443644
3870 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
3871 which dumps before the function entry point a data byte which represents
3872 the number of the local variables used by the specified function, added
3873 'xinst' for initial support for Extended Instruction Support,
3874 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
3875 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
3876 port->fun_prefix anymore (may change later),
3877 (genFunction, genEndFunction): do not store/restore local registers for
3878 _main (this should take care the --main-return command line option in
3880 (genOr): removed some legacy pic-port instructions,
3881 * src/pic16/genarith.c (genAddLit): re-enabled old code because
3882 performing operations with SFR's causes data to be written more than
3883 once to each SFR. Perhaps SFRs should be handled in special cases...
3884 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
3886 * src/pic16/main.c (_process_pragma): stack bound checking did not take
3887 into account for stack starting position,
3888 (struct OPTIONS pic16_optionsTable): added command line argument
3889 --extended or -y for Extended Instruction Support,
3890 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
3891 (deassignLRs): *** perhaps the most important change, old 'for' code
3892 (commented out for reference), didn't account for some registers which
3893 were left marked 'not free' after a pointer operation. The change
3894 reduces register usage a lot in some cases
3896 2006-03-04 Borut Razem <borut.razem AT siol.net>
3898 * support/regression/ports/hc08/spec.mk: remove *.asm in traget

6169 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
6170 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
6171 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
6172 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
6173 always available in leading double underscore form. The C99 support is
6174 mostly missing, but it's a start.
6175 * support/regression/tests/bug-227710.c: fixed nonconforming use of
6176 reserved identifier "__data".

6254 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
6256 * device/lib/printf_large.c: removed inline assembly for portability and
6257 readability. Use printf_fast if speed or size are more important.
6258 * src/pic16/gen.c: removed conditions around use of DEBUGpc
6259 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
6261 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
6263 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
6264 prevent compiler warning
6266 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
6268 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
6269 moved to level 0 and declared as static. Also they are explicit
6270 placed in access bank. This was necessery because some times they
6271 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
6272 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
6273 optimizations. Currently only compare to unsigned char is implemented,
6274 * src/pic16/gen.c: added fReturnIdx array,
6275 * (struct resolvedIfx) is moved to gen.h and made public,
6276 * (struct _G): added sregsAlloc and sregsAllocSet fields,
6277 * (aopForSym): added an optimization to directly store in stack of
6278 the operand of a SEND iCode,
6279 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
6280 but as registers instead (AOP_REG) using the fReturnIdx array,
6281 * (pic16_freeAsmop): remove the freed register from the
6282 _G.sregsAlloc field,
6283 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
6284 a compare of 'WREG',
6285 * (pic16_popGetTempRegCond): changed function prototype, now
6286 function takes also a bitVector argument v which holds the current
6287 set of registers that are allocated for stack access by aopForSym,
6288 registers allocated in aopForSym for accessing stack symbols are not
6289 any more part of the functions usedRegs field,
6290 * (genCall): some times aopOp is called for a stack variable to be
6291 send, aopForSym might perform the push, if this is true make sure
6292 that genCall doesn't push the variable twice by testing _G.resDirect,
6293 * (genFunction): changed testing for unspecified interrupt number
6294 from 256 to INTNO_UNSPEC,
6295 * modified selection scheme of frame pointer generation. Previously
6296 if function did use local registers a frame pointer was generated,
6297 now a frame pointer is generated only if function has arguments
6298 (that need PLUSW2 register access), or has stack arguments, or the
6299 compiler is not instructed to omit the frame pointer,
6300 * (genEndFunction): before restoring local registers that were saved
6301 in the function preamble, also restore the registers that *might*
6302 have been allocated for stack access,
6303 * (genRet): removed some old comments,
6304 * (genCmp, the active (RN's) version): added a call to the
6305 pic16_genCmp_special function to perform the compare with a more
6306 robust and optimized way,
6307 * (genInline): a feature has been added in inline code generation,
6308 which allows a wildcard variable substitution when writing inline
6309 assembly. Code is incomplete and experimental therefore undocumented,
6310 * (genCast): changed order of aopOp for result and right to allow
6311 aopForSym to directly load the result if possible,
6312 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
6313 perform an optimized compare on some selected special occasions,
6314 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
6315 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
6316 generate an IVT any more,
6317 * src/pic16/main.c (pic16_optionsTable): added command line option
6319 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
6320 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
6322 * src/pic16/NOTES: Raphael Neider added in list of active developers
6323 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
6324 jumptable_end to prevent bug #,
6325 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
6326 inCond and outCond fields,
6327 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
6328 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
6329 turn off register spilling,
6330 * (packRegsForOneUse): synced with other ports' versions although it
6331 is not used currently,
6332 * (pic16_packRegisters): added an optimization while reading
6333 structure bitfields, some registers may be saved (malloc code is
6334 decreased by 80 bytes)
6336 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
6338 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
6339 left is a bitfield, if yes, then don't optimize assignment. Perhaps
6340 this can be optimized more?
6342 2005-03-10 Raphael Neider <rneider AT web.de>
6344 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
6345 genNearPointerGet): (hopefully) fixed access to bitfields via
6346 pointers (p->bitN = x; and x = p->bitN; failed)
6348 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

6980 Adding support for replacing ljmps with sjmps in jumptables
6981 generated for switch statements. For now you need to set the
6982 environment variable SDCC_SJMP_JUMPTABLE to enable this.
6983 Now 4 algorithms for mcs51 jumptable generation are used:
6984 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
6985 addresses loaded pc-relative for up to 112 cases and stack-pushing
6986 target addresses loaded with offset from dptr for up to 256 cases.

7016 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
7018 * added libc directory. The current version of LibC contains string
7019 functions, ctype functions and macros and some functions of the
7020 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
7021 be extensively tested in the future. Standard disclaimer here.
7022 Library is not automatically build yet. But one can build it by
7023 invoking 'make' inside the libc directory.
7024 * added ADC library under libio. Preliminary version yet.

7034 * (pic16_storeForReturn): optimized return of 0,
7035 * (genCmp): experimental code for new genCmp which uses PIC18's
7036 special compare&skip instructions. Initial tests fail some times
7037 with variables grater than 1 byte in size, so new code is disabled,
7038 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
7040 * (genCast): began a fix to optimize the casting of a bit to another
7041 bit, now assigning a bitfield to another bitfield will fail, sorry,
7042 * src/pic16/main.c: disabled the use of lr-support feature,
7043 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

7050 and 1 for banking instruction,
7051 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
7052 caused stop processing pCodes after a inline assembly block,
7053 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

7055 registers when it shouldn't,
7056 * src/pic16/ralloc.c (allocReg): add preliminary support for
7057 supporting a limited set of temporary registers,
7059 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7061 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,

9973 * doc/Makefile (install): Changed to depth first to get rid of
9974 missing directory install warning.
9976 * as/Makefile (install-doc): Made work on Mac.
9978 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
9980 * src/SDCCast.c: added an additional type flow in decorateType() of
9981 opposite direction, see feature request #860006; it's enabled at runtime
9982 by setting the environment variable SDCC_NEWTYPEFLOW
9983 * src/SDCCast.h: changed prototype of decorateType()
9984 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
9985 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
9986 'char' to 'int' can be omitted, if both operands are 'unsigned char';
9987 see feature request #877103
9988 * src/SDCCval.c: updated call of decorateType()
9989 (valBitwise): fixed bug #882876
9990 (valMinus): added promotion
9991 (valLogicAndOr): result is unsigned
9992 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
9993 * src/SDCCsymt.c (computeType),
9994 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'
9995 must not cause an unsigned operation
9996 * src/pic/glue (pic14emitRegularMap),
9997 * src/pic16/glue.c (pic16emitRegularMap): updated call of decorateType()
9999 2004-01-23 Bernhard Held <bernhard AT bernhardheld.de>
10001 * src/pic/pcode.c (PCodeID): commented out left over debug code

10015 * src/pic/ralloc.c,
10016 * src/pic/ralloc.h: applied patch from Slade Rich;
10017 added support for multiple code pages and multiple RAM banks on the
10018 PIC 14 port. The ASM files now no longer simply assume all the
10019 code / RAM are in the same page / bank. This means the linker can
10020 safely allocate code/RAM of separate ASM files to different pages/banks.
10021 * doc/sdccman.lyx: added Slade's tips
10022 * src/mcs51/peeph.def: fixed bug #880768

10034 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
10035 strtof is not part of C89 and isn't included with Mac OS X.
10037 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10039 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

10064 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
10066 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
10067 loaded with the linker search paths (-L arguments) and the libraries
10068 to be linked with the current source (-l arguments). Changes
10069 currently will affect only the pic16 port.
10070 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
10071 include path the port specific paths and port specific libraries,
10072 * gplink command now contains the $3 argument,
10073 * src/pic16/device.h,
10074 * src/pic16/device.c,: structure PIC_device is made public and
10075 renamed to PIC16_device, the same for variable Pics which is renamed
10076 to Pics16. Updated all references to them.
10077 * src/pic16/glue.c (pic16glue): corrected bug with code
10078 initialization which bypassed the variable initializations block.
10080 * device/lib/pic16/Makefile.rules: removed --penable-stack from
10081 COMPILE_FLAGS and added the --nostdinc option

10088 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
10090 Documenting changes from previous commits.
10091 * configure.in (version 1.56),
10092 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
10093 when generating output files to configure the pic16 library,
10094 but now I've commented it out, since gputils aren't installed in the
10095 SF compile farm, so library won't compile
10097 * device/lib/Makefile.in (version 1.56): initially I've added in
10098 target 'all' the prerequestive 'model-pic16' so it compiled the
10099 pic16 library, but now I've commented it out for the same reasons
10101 * added targets 'model-pic16' and 'objects-pic16' to compile the
10103 * added target 'port-specific-objects-pic16' to handle the
10104 generated libraries and copy them into the build/ directory
10105 * added target 'clean-intermediate-pic16' to clean intermediate
10106 files into pic16 directory
10107 * in target 'installdirs' added line to create directory pic16 in
10108 the installation path
10110 * device/include/Makefile.in (version 1.11): in target 'install'
10111 added lines to copy all header files to installation path,
10112 * in target 'installdirs' added line create directory for pic16
10113 headers in the installation path

10126 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10128 * src/z80/main.c (_parseOptions): fixed the portmode= command line
10129 option so that it actually works. Made it specific to the z80, since
10130 the gbz80 doesn't have these kinds of I/O ports.
10132 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10134 * device/include/z180.h,

10158 via literal number. The symbol is placed in the corresponding
10159 position of the data ram
10160 * (pic16_dump_section): relocatable and absolute uninitialized
10161 data are now emitted in sorted order to reduce section naming,
10162 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
10163 weren't marked as being in the access bank,
10165 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
10167 Added portion of GNU PIC Library under the directory
10168 device/include/pic16 and device/lib/pic16. These files
10169 contain the declarations of SFRs for the PIC18Fxx2 devices.
10170 The directory is initialized via configure from toplevel.
10172 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
10174 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
10175 the spilllocations to be compared correctly
10177 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
10179 * src/SDCCast.c (decorateType): fixed bug introduced today
10181 2004-01-12 Borut Razem <borut.razem AT siol.net>

10199 * doc/sdccman.lyx: Moved and added some sections, small changes
10200 all over. Telling LaTeX to be less strict with word spacing
10201 to better keep the right margin. Changed some notes about
10202 maintainance of the ports in section 3.2.1 - is it OK like this?
10204 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

10244 * src/pic16/peeph.def: all peepholes with movff are commented out,
10245 because there is a problem in the pcode peep optimizer,
10246 * src/pic16/ralloc.c: the register allocator can now reuse local
10247 function symbols for another function. This saves register usage.

10387 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
10389 * sdcc.spec: updated

10395 * src/ds390/gen.c (genRightShift): fixed bug #870788
10396 * src/SDCCast.c (decorateType): fixed bug #870781
10398 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
10400 PIC16 port related changes:
10401 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
10402 added variable stackPos,
10404 * gen.c: genCall, assignResultValue: added support for
10405 pushing/retrieving function parameters to/from stack,
10406 genFunction,genEndFunction: setup stack frame for the
10407 generated function,
10408 genAddrOf: will be changed according to bug 863624
10410 * added files genutils.c and genutils.h which contain gen*
10411 debugged and optimised functions extracted from gen.c
10413 * glue.c: added variable 'externs' which holds extern symbols,
10414 pic16emitRegularMap: is modified to properly handle relocatable
10415 symbols under the new scheme,
10416 pic16createInterruptVect: is modified
10417 pic16printPublics: is modified to emit 'global' assembler directives,
10418 added pic16_printExterns to print extern symbols,
10419 pic16glue: initializes stack/frame pointer in the beginning of
10420 the assembly output. Temporary hack, will be corrected later,
10421 because gplink yet does not support stack and SDCC does not
10422 yet support a type of crt0.o object to create the final binary.
10424 * Removed many lines that contain 8051 legacy code.
10425 * The code is finally placed under a 'code' directive.
10426 * Added port specific options.
10428 * _process_pragma: simplified since now we do not need *special*
10429 include file to define SFR registers. But a separate header
10430 will be needed. This will be developed later.
10431 * _pic16_parseOptions: added, parses port specific options:
10432 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
10433 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
10434 --preplace-udata-with=
10436 * _pic16_setDefaultOptions: modified to initialize section names,
10437 but hack is temporarly out of order since it needs improvement.
10438 * _pic16_genAssemblerPreamble: configuration words are emitted by
10439 their address instead of their name. This part is incomplete and
10440 supports only the 18Fxx2 devices. Other devices will emit an error
10441 during assembly since they do not contain the same set of config
10443 * _pic16_genIVT: is modified,
10445 * pcode.c: added definitions for some hardware registers that are needed
10447 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
10448 All PCI entries are updated. Now LFSR is supported.
10449 * Removed pic16_pciTRIS is mentioned by mdubuc in source
10450 * added pic16_newpCodeOpLit2 to support instructions with
10451 two literal arguments
10452 * pic16_pCode2str: corrected code that emits assembler instructions
10453 with two literal operands and those that have an access bit modifier
10454 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
10455 this fixes a bug which caused some labels to be lost, when an
10456 assembler directive was added, i.e. banksel,
10457 * pic16_FixRegisterBanking: improved logic that causes the insertion
10459 * InlineFunction: functions that are called once, are not any more
10460 inlined. This can be a port option in the future,
10462 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
10464 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
10465 hold the corresponding uninitialized symbols,
10466 * pic16_allocProcessorRegister: registers have explicit marked the
10468 * pic16_allocInternalRegister: registers are explicit marked as
10470 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
10471 processing list, so bit registers were lost,
10474 * ralloc.h: added field 'accessBank' and original symbol operand
10475 in register definition,
10476 * removed the field isMapped from register definition,
10478 ** Several functions have been removed from various sources:
10479 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
10480 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
10481 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
10482 pic16_assignRelocatableRegisters
10484 ** others have been introduced:
10485 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
10486 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
10488 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
10490 * support/scripts/inc2h.pl: changed definition of BIT_AT
10491 to emit 'sbit at' instead of 'bit at'. This was a request.
10493 PIC16 port related preliminary changes:
10494 * gen.c: prefixed function popRegFromString with
10495 pic16_ and all references to it corrected
10496 * pcode.c: all pic16_pc_* hardware registers prefixed
10497 with underscore (_),
10498 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
10499 * ralloc.c: newReg(): when register is REG_SFR then
10500 set address to rIdx,
10501 pic16_allocProcessorRegister(): marks register wasUsed=0
10502 pic16_writeUsedRegs(): added a call to assign processor
10503 registers via pic16_assignFixedRegisters
10505 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10507 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
10508 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
10509 variables in unused register banks. Also the SSEG is placed
10510 wherever there is enough space for it, and IDATA can be anywhere
10511 in internal RAM. For now compile using -Wl-Y[stack_size].
10512 The mem file is different for this option as well, since it
10513 makes no sense of talking about DSEG lenght.
10515 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
10517 * src/SDCClrange.c: fixed bug 869095 that caused segfault
10518 in certain cases, e.g. when ROM assignment, patch provided
10519 from Albert den Haan.

10762 * src/SDCCast.c (decorateType): disabled a transformation I added in
10763 revision 1.188 (access to fields of a structure at an absolute address);
10764 it breaks with bitfields, extern declarations, and gcse analysis.
10765 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
10766 could be assigned through a pointer, so don't complain.
10767 * src/SDCCast.c (astErrors),

11384 2003-09-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11386 * src/mcs51/gen.c (genFunction, genEndFunction),
11387 * src/ds390/gen.c (genFunction, genEndFunction): Moved save
11388 and restore of EA so that stack offsets to parameters are
11389 correct when using both critical and reentrant/stack-auto.
11390 * src/z80/gen.c (aopOp): removed erroneous assertion about sloc
11391 size (can be triggered in error if sloc is shared between
11392 different sized objects)

11404 * src/SDCCsymt.c (sclsFromPtr),
11406 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
11407 support for standard C idiom of memory mapped variables; for
11408 example, *((xdata int*)0x1234) = 1 is now internally equivalent
11409 to xdata int at 0x1234 tempvar = 1.

11427 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11429 Fixed bug #621531 (const & volatile confusion in the type chain).
11430 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
11431 refer to the const or volatile state of the pointer itself.
11443 * src/pic16/ralloc.c
11444 * support/regression/tests/const.c
11446 2003-09-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11448 When checking for duplicated modules, use absolute paths

11501 2003-09-04 Bernhard Held <bernhard AT bernhardheld.de>
11503 * device/lib/_mullong.c: replaced int by short for gcc
11505 2003-08-31 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11507 * src/SDCCpeeph.c (notVolatile, notVolatileVariable): handle IFX
11508 and JUMPTABLE iCodes properly now (worked by accident before)
11509 * src/mcs51/gen.c (leftRightUseAcc),
11510 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
11511 iCode properly now. Use getSize instead of nRegs since a & b
11512 aren't part of the nRegs tally.
11514 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
11516 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

11525 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
11526 copied from genNearPointerSet()
11527 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
11528 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
11529 If they pop r0/r1 they must be called in the opposite order than aopOp().
11530 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
11531 (resp. --stack-auto), prepared for --xstack
11533 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
11535 * doc/sdccman.lyx: reverted tables to those in cvs 1.64
11537 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>

11542 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
11544 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
11545 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
11546 type for bits was changed. It resulted in bit variables becoming
11547 global, which is not permitted in PIC 14 assembly output.
11549 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
11551 * doc/sdccman.lyx: various additions and updates. Rearranged sections
11553 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11555 Z80 and MCS51 linkers complaint if a public symbol is defined
11556 in more than one library module:

11562 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11564 A few small changes that speed up the peephole optimizer.
11568 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11570 Try to make the peephole optimizer smarter by maintaining
11571 an association between the assembly source code and the
11572 iCodes that originated them. Put this information to use
11573 with a new peephole rule condition "notVolatile" so that
11574 the rules can be aggressive yet still safe.
11579 * src/mcs51/peeph.def
11581 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11585 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
11586 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
11587 if the left or right operand symbols have the accuse flag set.
11589 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11591 Changed the type of the result of the ! (NOT) operator to char;
11592 previously it returned the same type as the source. This allows
11593 us to eliminate all the genFloatNot functions (all of its target
11594 implementations were very buggy) since !float can use the same
11597 * src/SDCCicode.c (ast2iCode): ! returns char
11598 * src/mcs51/gen.c (genNot, genNotFloat),
11599 * src/ds390/gen.c (genNot, genNotFloat),
11600 * src/z80/gen.c (genNot, genNotFloat),
11601 * src/pic/gen.c (genNot, genNotFloat),
11602 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
11604 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
11606 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
11607 1. Interrupt would not compile properly. Ensure PCLATH register is saved
11608 during interrupts. Ensure WSAVE is located at a shared bank address.
11609 2. Fixed page selection in some places
11610 3. Fixed BTFSS/C to where necessary use registers directly and not simply
11611 the registers name strings.
11612 4. Fixed "signed / unsigned compare" compiler warnings.
11613 5. The PIC port manages its own allocation of the general purpose
11614 registers, but makes no attempt to reuse them. As a result when
11615 compiling it soon runs out of general purpose registers. Some
11616 additional code was added to the files pcode.c and device.c to walk
11617 through the function call tree and rename the registers so that they
11627 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
11628 genPlus() & genMinus() when the result is the same as left or right
11630 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

11634 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11636 Made bitfield a distinct type from bit so that bitfields
11637 convert as per ANSI C and bits retain their traditional
11638 boolean style behaviour. Implemented bitfield support in
11646 * src/ds390/gen.c: bit v bitfield split
11647 * src/z80/gen.c: New support for bitfields
11648 * support/regression/tests/bitfields.c: reenabled z80,
11651 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
11653 Rules 246.x, 247.x relate to bitfields, the others speed up
11654 access to xdata mapped I/O devices.
11656 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
11658 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11660 Cleaned up genPackBits and genUnpackBits and added two helper
11661 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
11662 for literal assignments in genPackBits (thanks to Frieder for
11668 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11670 Fixed bug #748310 (pointer to function type mishandled when the
11671 function name is omitted). Also fixed a SIGSEGV when a function
11672 attribute (reentrant, etc) is used on a non-function or on a
11673 function but misplaced before the parameter list.
11675 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
11677 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
11678 * support/Util/SDCCerr.h,
11679 * support/Util/SDCCerr.c: Added func attr misuse error msg
11681 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
11683 Fixed bug #787649 by anonymous
11684 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
11685 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
11687 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11689 Fixed numerous bitfield problems.
11691 * src/SDCC.y: More bitfield related error checking

11698 * support/regression/tests/bitfields.c: tests added
11700 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11702 Made the constant following the "interrupt" keyword optional. If
11703 omitted, the function will not automatically be given an entry
11704 in the interrupt vector table (similar to #pragma NOIV, but
11705 less syntacticly kludgy). The interrupt number is also now
11706 range checked. Also fixed a bug in the high order bit example

11714 * support/Util/SDCCerr.h
11717 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

11720 * src/SDCCicode.c (operandOperation): rewritten some ops
11721 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
11722 * src/SDCCsymt.c (computeType): literals are handled the same way as any
11724 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
11725 be re-activated by defining REDUCE_LITERALS)
11726 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
11727 unsigned, but are signed by default
11728 * src/SDCCval.c (constVal): rearranged
11729 * src/SDCCval.c (valMod): preliminary fix
11730 * src/SDCCval.c (valCastLiteral): use TYPE_* types

11770 * src/SDCCval.c (cheapestVal, valueFromLit): use TYPE_* types
11771 * src/SDCCval.c (constVal): changed default to signed; hex and octal
11772 constants are unsigned; added recognition of "u" flag for unsigned
11773 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
11774 * src/SDCCval.c (valDiv, valMod): fixed signdness
11775 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
11776 signedness of modulo, left and right shift

12238 support for the PIc16 port in the ports table, when executing
12239 the compiler with no port specified on command line, a default
12240 port is selected with the new macro DEFAULT_PORT which is
12241 defined in port.h, in setDefaultOptions() linkOptions is removed
12242 from initialization assignment, since now it is a set,
12243 parseCmdLine uses setParseWithComma for linkOptions, in
12244 linkEdit() linkOptions are accessed with new function indexSet()
12245 which returns the i'th item of a set variable. See SDCCset.c, in
12246 linkEdit() when calling buildCmdLine(), added linkOptions as
12247 last argument. Now users can pass arguments to gplink via the
12248 -Wl option, main() uses pic16glue() to glue up pic16 programs

12262 gpasm complaining and test the linkage with gplink, _linkCmd and
12263 _asmCmd changed to be more gplink and gpasm friendly
12264 * src/pic16/peeph.def: peep rule 3 is commented out, since it
12265 produced an error when parsed, peep rule 12 is added to utilize
12266 movff, but it is commented out since the pCode does not support
12267 yet a command with 2 address arguments

13329 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
13330 * src/mcs51/main.c: removed {bindir}{sep} from aslink
13332 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13334 * in /sdcc/as/mcs51/ changed these files in order to create an
13335 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
13336 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
13337 following files to include the previous two files: aslink.dsp,
13338 Makefile.aslink, Makefile.bcc, and Makefile.in.
13340 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
13341 .adb instead of .cdb
13343 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13345 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
13346 value from option --iram-size.
13348 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13350 * /sdcc/as/mcs51/lklist.c: added boundary check before using
13353 2002-09-18 <wiml AT hhhh.org>
13355 * SDCClrange.h: exposed setFromRange() and setToRange()
13356 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
13357 packRegsForAccUse() (bug 542397)
13358 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
13359 multiple times and emitting the fetch operations more than once
13360 added aopGetUsesAcc() function to allow binary operators to
13361 fetch their operands in the correct order; made genMinus() emit
13362 compact code for X = LITERAL - Y
13364 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13365 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
13366 sprintf() in line 1267.
13368 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13369 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
13372 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13373 Changes to aslink (All the changes are marked with 'JCF'):
13375 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
13378 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
13379 area BSEG. Also moves, if possible, the DATA area down into the internal
13380 ram so more space is available.
13382 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
13385 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
13386 not bytes. Function summary() which creates a memory usage summary
13387 file with extension .mem. Reports of overlaping stack and small stack
13388 size. If the space for the stack is less than 16 bytes aslink trows a
13391 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
13392 the 8051. Option 'y' for memory summary output file.
13394 Changes to sdcc (All the changes are marked with 'JCF'):
13396 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
13398 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
13399 overlaying area for it (uses RegBankUsed[4]).
13401 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
13402 bank zero as used by default. By default aslink locates the stack
13403 (equivalent to --stack-after-data). Pass option 'y' to aslink for
13404 the creation of the .mem file. Delegates the allocation of data area
13405 to aslink (it is not longer 0x30 by default). If --stack-loc passes
13406 the begining of the stack area to aslink.
13408 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
13409 glue() in SDCCglue.c creates an area for it.
13411 2002-09-03 Borut Razem <borut.razem AT siol.net>
13412 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
13413 sdcc/src/pic/glue.c:
13414 introduced atexit() handler for teporay files removal in case of
13415 errors, assertions, ...
13417 2002-08-29 Borut Razem <borut.razem AT siol.net>
13418 * sdcc/support/cpp2/auto-host_vc_in.h:
13419 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
13420 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
13421 Maybe there is a similar problem with BORLANDC? It should be checked!
13423 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
13424 corrected improper use of assert: the assignment to clr variable was done inside the assert.
13425 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
13426 was not executed, and the compiler (cl) launched a warning:
13427 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
13429 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
13430 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
13432 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
13433 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
13435 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
13436 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
13437 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
13438 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
13439 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
13440 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
13441 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
13442 - added Release configuration in VS projects
13443 - review of compiler an linker options
13444 - VC .exe files are generated in bin_vc directory, not to interfere
13445 with binaries generated from other projects (cygwin, mingw, bcc ...)
13447 * sdcc/src/yacc.dsp: added
13449 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
13450 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
13451 and insert the version number definitions from .version
13453 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
13455 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
13456 added - genarate auto-host.h using auto-host_vc_in.h as template
13459 removed from CVS, generated automatically
13461 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
13462 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
13464 2002-08-11 Borut Razem <borut.razem AT siol.net>
13465 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
13467 2002-08-10 Borut Razem <borut.razem AT siol.net>
13468 * src/SDCCmain.c (main):
13469 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
13470 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
13471 The consequence was that some temporary files were not removed.
13474 unification of code in functions tempfilename() and tempfile():
13475 function tempnam() is defined in Visual Studio 6.0 and .NET
13477 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
13479 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
13480 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
13481 - removed compiler command line option /WX: Treats all warnings as errors
13482 - update a list of source files, included into the project
13484 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
13485 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
13486 changed project type to Generic Project so that can be correcly converted to VS.NET project
13488 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
13490 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
13492 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
13494 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
13495 added return 0 statements after assert() to make compiler happy
13497 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
13498 added newline in the def file to keep MSC compiler satisfied
13500 * sdcc/src/z80/gen.c:
13501 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
13502 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
13503 - solved MSC error in function aopDump()
13505 * sdcc_vc.h: define PREFIX as "\\sdcc"
13507 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
13508 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

13511 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
13512 - Rewrote the register banking algorithm.
13513 - Added pCode live-range analysis to registers (for now, only non-used and
13514 singly-used registers optimized away)
13516 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
13518 * 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.

13547 2002-03-28 Johan Knol <johan AT balder>
13549 * src/SDCCval.c: fixed bug #532436
13551 2002-03-14 Scott Dattalo <scott AT dattalo.com>
13553 Added "char *Processor" field to the port structure.
13556 Added -p option. Allows port dependent processor to be specified.
13559 Initialized the new field char *Processor field to NULL in all ports
13562 Compiler generated registers for interrupt context saving
13563 were not getting allocated.
13565 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
13568 Fixed left shift. Will promote the left side of a left shift
13569 if a) left shifting more than size of operand or b) when assigned
13570 to something size > size of left side
13572 2002-03-14 Scott Dattalo <scott AT dattalo.com>
13574 tons of changes. Register allocation has been
13575 rewritten. Added customization for the various PICs. Flow
13576 analysis is restructured. ...

13587 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
13589 2002-03-04 johanknol <johanknol AT manik>
13591 * /src/SDCCval.c: fixed
13593 const unsigned char arr[][2] = { { 0, 1 } };

13683 Previous fix was not good. basic blocks that have "break" or "return" are
13684 not really partof a loop , but live ranges used in these blocks should
13685 be live thru the entire loop, so set partOfLoop but don't add them to
