------- Comment #10 from aoliva at gcc dot gnu dot org 2009-10-13 20:08 ------- This means the testcase labeled pr41264-test.c was totally unrelated to the original bug report :-( Oh well... I'll add the other testcase to my ongoing efforts to speed up var-tracking. I'm working on that on two fronts:
1. speed up dataflow analysis while reducing memory use, by chaining and partially-sharing variable hash tables, and speeding up lookups with bit-fields. 2. speed up emission of notes by caching the results of expanding location expressions, rather than repeatedly expanding then and often throwing the results away I'm afraid both of these are lower priority than wrong debug-info introduced in the scheduler, as in bug 41535. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41264
