I had ported the -old version to OS9,TOS (Atari ST) and Minix and the new version 2.1 Beta -to Minix and TOS. - -While porting and using flex I detected a bug and made some improvements. -I have included a shared, compressed and uuencoded file contaning all cdiffs -and additional files (Sorry, but I'm on EBCDIC-Bitnet) and a short discussion -of the changes. Even some of the TOS specific changes might be of general -interest ! - -I posted these cdiffs to the minix discussion group, but I think it's up -to you to post them to the unix-sources group. If you plan to post even -the TOS compiler specific patches please contact me because there might be -further compiler (P.D.) additions. If you have an interest I could also -port the new version to OS9 -- this is a little bit more difficult, because -OS9 uses CR as end of line character (the EOL char. is coded into the -initscan.c tables,...). It is necessary to change all occurences of '\n' to -macros and variables and it's useful to add a new -n options (see commented -line in main.c) - - - -The changes: (1.7.89 RAL) - - - Bug fix: The original flex didn't like trailing spaces in exclusive start - condition lists ! If you add an trailing space to line 68 in scan.l - - "%x SECT2 SECT2PROLOG SECT3 CODEBLOCK PICKUPDEF SC CARETISBOL NUM QUOTE " - - you get a misleading error message: - - "Syntax error at line 69: bad start condition list" - - This bug can either be fixed in parse.y or in scan.l . I have chosen the - last because there the fix is minimal: Just change the rule (line 128) - - "\n" to "{OPTWS}\n" - - - Enhancements: - - new option "-?" that provides some help information about the other - flags (main.c) - - new option "-aTMPPATH" that allows a redefinition of the standard - path for the temporary file (this might be rather large >200k if - F,f options are selected). (main.c, flexdef.h (l.376)) - - hexdump of illegal characters -- this proved to be a useful debugging - tool especialy if invisible control characters occur which weren't - covered by the rules. (scan.l fprintf statement line 129,...) - - - Patches due to TOS - - General: TOS uses CR,LF as end of line char., Flex wants only a single - LF as EOL char. Therefore all I/O must be translated using f* calls. - This is done everywhere besides the YY_INPUT macro (flex.skel (scan.c), - line 31) that uses a low level 'read'. This should be definitly changed - to fread, so that all I/O calls occur on the same level. - - the short action_file_name has been "flexXXXXXX.tmp", but that's too - much for TOS,MSDOS ! I changed it to "flexXXXX.tmp" in main.c (patch - covered by the -a option additions) - - some compilers don't like external names that are ambiguous within - the first 8 characters. I defined macros that change all these long - external names to names that are unique within the first 8 characters. - Just define SHORT_EXTERNAL_NAMES to use this feature (flexdef.h) - - some statement changes that some compiler don't like: - typedef *xxx[] -> typedef **xxx (flexdef.h.,l.308) - "/*" -> '/','*' within a comment in (scan.l, l.209) - - changed short "lexyy.c" to "lex_yy.c" what's more similar to the unix - "lex.yy.c" (main.c). - - a few further really compiler dependent changes provided with - #ifdef ATARI && LATTICE res. TURBO braces. - - - Additional TOS only files - - Makefile.tos: Common makefile for all TOS compilers. If you add further - ones please email me the new makefile. - - flex.lnk: Lattice - GST linker argument extension file - - flex.tlk: Turbo linker argument extension file - - -Additional remarks: - -I didn't add a new initscan.c (= flex -ist scan.l). The current one is good -enough for a first compilation. With this first version of flex you can -rebuild your own scan.c and the final flex version ! - -Minix ST : - - I had to "chmem =70000 cv" (>50000) to get flex linked - - 'memset' (PC 1.3, EFTH40,...) is necessary - - chmem =90000 flex may be sufficient - -Minix PC : - It should be possible to port Flex to Minix PC. The current sizes of flex - are: - Minix ST (ACK) Lattice (TOS) Turbo (TOS) - - size 75300 83305 57957 - compilation time 22' 15' 3'40" - flex -is scan.l 1'49" 43" 30" - - The Minix ST size includes the bad generated code using only a subset of - the 68000 commands, long addresses only and a huge relocation table. - Therefore the PC size will be <64 k ! More serious is the fact that I had - to chmem =90000 flex to get scan.l converted to scan.c . But I never saw - a more complex lex source than scan.l -- so it should be possible to - reduce some array sizes without limitation for all day usage. - - No one volunteered yet for a Minix PC port -- but if someone will try it - I would provide him with a new scan.c and some hints. - -TOS: - Don't forget to adapt the flexskel path within flexdef.h ! - - -Bitnet: V61@DHDURZ1 Ronald Lamprecht -UUCP: ...!unido!DHDURZ1.bitnet!V61 Theoretische Physik -ARPAnet: V61%DHDURZ1.BITNET@CUNYVM.CUNY.EDU (Heidelberg, West Germany) -(Message inbox:36) -Date: Wed, 05 Jul 89 21:16:07 CET -From: V61%DHDURZ1.BITNET@csa2.lbl.gov -Subject: Re: What is TOS -To: vern@lbl-csam.arpa - -TOS is the name of the Atari ST operating system that is very similar -to MSDOS (Both use CR,LF as end of line character).

Readme2 -sed '/^X/s///' > Readme2 << '/' -XThe changes: (1.7.89 RAL) -X -X - Bug fix: The original flex didn't like trailing spaces in exclusive start -X condition lists ! If you add an trailing space to line 68 in scan.l -X -X "%x SECT2 SECT2PROLOG SECT3 CODEBLOCK PICKUPDEF SC CARETISBOL NUM QUOTE " -X -X you get a misleading error message: -X -X "Syntax error at line 69: bad start condition list" -X -X This bug can either be fixed in parse.y or in scan.l . I have chosen the -X last because there the fix is minimal: Just change the rule (line 128) -X -X "\n" to "{OPTWS}\n" -X -X - Enhancements: -X - new option "-?" that provides some help information about the other -X flags (main.c) -X - new option "-aTMPPATH" that allows a redefinition of the standard -X path for the temporary file (this might be rather large >200k if -X F,f options are selected). (main.c, flexdef.h (l.376)) -X - hexdump of illegal characters -- this proved to be a useful debugging -X tool especialy if invisible control characters occur which weren't -X covered by the rules. (scan.l fprintf statement line 129,...) -X -X - Patches due to TOS -X - General: TOS uses CR,LF as end of line char., Flex wants only a single -X LF as EOL char. Therefore all I/O must be translated using f* calls. -X This is done everywhere besides the YY_INPUT macro (flex.skel (scan.c), -X line 31) that uses a low level 'read'. This should be definitly changed -X to fread, so that all I/O calls occur on the same level. -X - the short action_file_name has been "flexXXXXXX.tmp", but that's too -X much for TOS,MSDOS ! I changed it to "flexXXXX.tmp" in main.c (patch -X covered by the -a option additions) -X - some compilers don't like external names that are ambiguous within -X the first 8 characters. I defined macros that change all these long -X external names to names that are unique within the first 8 characters. -X Just define SHORT_EXTERNAL_NAMES to use this feature (flexdef.h) -X - some statement changes that some compiler don't like: -X typedef *xxx[] -> typedef **xxx (flexdef.h.,l.308) -X "/*" -> '/','*' within a comment in (scan.l, l.209) -X - changed short "lexyy.c" to "lex_yy.c" what's more similar to the unix -X "lex.yy.c" (main.c). -X - a few further really compiler dependent changes provided with -X #ifdef ATARI && LATTICE res. TURBO braces. -X -X - Additional TOS only files -X - Makefile.tos: Common makefile for all TOS compilers. If you add further -X ones please email me the new makefile. -X - flex.lnk: Lattice - GST linker argument extension file -X - flex.tlk: Turbo linker argument extension file -X -X -XAdditional remarks: -X -XI didn't add a new initscan.c (= flex -ist scan.l). The current one is good -Xenough for a first compilation. With this first version of flex you can -Xrebuild your own scan.c and the final flex version ! -X -XMinix ST : -X - I had to "chmem =70000 cv" (>50000) to get flex linked -X - 'memset' (PC 1.3, EFTH40,...) is necessary -X - chmem =90000 flex may be sufficient -X -XMinix PC : -X It should be possible to port Flex to Minix PC. The current sizes of flex -X are: -X Minix ST (ACK) Lattice (TOS) Turbo (TOS) -X -X size 75300 83305 57957 -X compilation time 22' 15' 3'40" -X flex -is scan.l 1'49" 43" 30" -X -X The Minix ST size includes the bad generated code using only a subset of -X the 68000 commands, long addresses only and a huge relocation table. -X Therefore the PC size will be <64 k ! More serious is the fact that I had -X to chmem =90000 flex to get scan.l converted to scan.c . But I never saw -X a more complex lex source than scan.l -- so it should be possible to -X reduce some array sizes without limitation for all day usage. -X -X No one volunteered yet for a Minix PC port -- but if someone will try it -X I would provide him with a new scan.c and some hints. -X -XTOS: -X Don't forget to adapt the flexskel path within flexdef.h ! -X -X -/ -echo x - flex.lnk -sed '/^X/s///' > flex.lnk << '/' -X* -X* -X* linker control file for flex.ttp -X* -X* -X* -XINPUT d:\latt\lib\startup.bin -X* -XINPUT ccl.bin -XINPUT dfa.bin -XINPUT ecs.bin -XINPUT gen.bin -XINPUT misc.bin -XINPUT nfa.bin -XINPUT parse.bin -XINPUT sym.bin -XINPUT tblcmp.bin -XINPUT main.bin -XINPUT yylex.bin -XINPUT scan.bin -X* -XLIBRARY d:\latt\lib\clib.bin -X -/ -echo x - flex.tlk -sed '/^X/s///' > flex.tlk << '/' -Xccl.o -Xdfa.o -Xecs.o -Xgen.o -Xmisc.o -Xnfa.o -Xparse.o -Xsym.o -Xtblcmp.o -Xyylex.o -Xmain.o -Xscan.o -Xd:\turbo\lib\tcstdlib.lib ; standard lib -Xd:\turbo\lib\tcextlib.lib ; extended lib -Xd:\turbo\lib\tctoslib.lib ; TOS lib -Xd:\turbo\lib\tcgemlib.lib ; AES and VDI lib -X-S=200000 -/ |
