URL: https://dev.monetdb.org/hg/MonetDB/rev/40121743c4b6
Modified Files:
monetdb5/mal/mal_instruction.c
monetdb5/mal/mal_prelude.c
Branch: Dec2025
Log Message:
Reduce number of GDKmalloc calls by more than 5000 during initialization.
We do this by allocating two chunks in one alloc instead of two separate
allocs.
