The differences between this yacc and a stadard version 6 yacc 1410c3f5c9Smckusickare indicated in a comment in y1.c. 1510c3f5c9Smckusick 1610c3f5c9SmckusickNote that the standard yacc parser will not work on the tables produced 1710c3f5c9Smckusickby "eyacc" and also that these changes are really useful only with 1810c3f5c9Smckusicka fairly large set of error recovery routines which are part of both 1910c3f5c9Smckusick"pi" and "pxp". The routines are language independent, but the method 2010c3f5c9Smckusickwill only work on languages which have some redundancy in them... it is 2110c3f5c9Smckusickprobably ill suited for C, but would work fine in ALGOL-60, ALGOL-W, 2210c3f5c9SmckusickEUCLID, LIS, SP/K, PL/1, ALPHARD, CLU, ... 2310c3f5c9Smckusick 2410c3f5c9SmckusickSun Apr 8 21:43:08 PST 1979 2510c3f5c9Smckusick 2610c3f5c9SmckusickA paper describing the method used by eyacc will appear in August in the 2710c3f5c9SmckusickSIGPLAN Boulder conference. 2810c3f5c9Smckusick 2910c3f5c9SmckusickMon May 5, 1980 3010c3f5c9Smckusick 3110c3f5c9SmckusickThe eyacc in this directory has been modified to work for 3210c3f5c9Smckusickversion 7. This involved syntax fixes and changing the I/O calls 3310c3f5c9Smckusickto standard version 7 calls. 34
