*---*---*---*---* 8-Nov-1999: I have a problem with aslink (with the exe-file you supply with v2.2 as well as my own built aslink) under Linux OS. The files from the ExApp Project: (from simpleRTJ - simple Real Time Java for the m68hc11, http://members.xoom.com/simpleRTJ/Trials/Introduction.html) cause a segmentation fault. Under DOS the hole project is correctly built, also with the aslink-input files, that i build with as6811 under Linux ! So problem seems to be aslink. Maybe you have a clue !? Sincerely, Ingo Beckmann [ingo.beckmann@FernUni-Hagen.de] Ingo, There is a bug in ASLINK: The Linux function 'fclose(sfp)' causes a segmentation fault if the file (having a file handle sfp) has already been closed. (The file handle becomes invalid after the file is closed, a subsequent call to fclose(sfp) with the invalid file handle causes the segmentation fault.) The bug is that after I closed the input file I did not set the file handle to NULL so that the routine LKEXIT() would not try to close the file a second time. (The DOS libraries seem to have a method to verify if the file handle is valid before using it.) Version 2.3 fixes this problem. *---*---*---*---*
*---*---*---*---* 20-Nov-1998: I am in the process of developing a Freeware C compiler for 8-16 bit microcontrollers , and have decided to use ASXXXX as the assembler. Now the question.... I like the idea of local labels a lot .. since this will save a lot of effort in name mangling ... but to use this effectively I need to expand the 256 limit to something in the range of 2^15 .. is this feasable ?? Which source files will I need to modify to accomplish this ?? Thanks in advance Regards Sandeep -- +---------------------------------------------------+ | Sandeep Dutta : Sandeep_Dutta-CSD001@email.mot.com| | Motorola Inc. : LMPS Software Research Lab | +---------------------------------------------------+ Sandeep, Modify ASXXXX.H Changing the variable type from 'char' to 'int' for t_num and t_flg in the structure tsym will increase the allowable number of temporary symbols to 65536 (0 - 65535) between normal symbol definitions. The definition for the structure tsym is found in ASXXXX.H Recompile the assemblers. Note that the temporary symbols are not hashed. A linear search is used to find the symbol and may take some time if there are many thousands of symbols between two normally constructed symbols. /* **-- ASXXXX.H --** */ /* ** BEFORE ** */ struct tsym { struct tsym *t_lnk; /* Link to next */ char t_num; /* 0-255$ */ char t_flg; /* flags */ struct area *t_area; /* Area */ addr_t t_addr; /* Address */ }; /* ** AFTER ** */ struct tsym { struct tsym *t_lnk; /* Link to next */ int t_num; /* 0-65535$ */ int t_flg; /* flags */ struct area *t_area; /* Area */ addr_t t_addr; /* Address */ }; *---*---*---*---*
