Hi! I spend four hours on optimizing memeqzero, as you can see from my blog post at http://rusty.ozlabs.org/?p=560 Module of the Month: tcon (CC0) ============================== tcon is a subtle module for other modules to create type canaries: eg, ccan/tlist has a TLIST_TYPE(name, type) which declares a list which holds "type". tcon provides TCON_WRAP() helpers to add a canary to a declaration tcon_unwrap() to access it, and tcon_check() to warns if an expression isn't the same type as the canary.
In addition, canaries can now encode positive compile-time values using TCON_VALUE, which can be accessed using tcon_value. New modules: ============ lpq: simple priority queue (David Gibson) Minor updates & bugfixes: ======================== isaac: info formatting fixes (Paul Wayper) lqueue/lstack: use ccan/tcon (David Gibson) mem: new routine memiszero opt: don't use malloc for errors if they set opt_allocator. order: total_order_cmp helper (David Gibson) ptrint: CONST_FUNCTION annotation (David Gibson) tal/str: fix for tal_strndup() of non-nul terminated strings tcon: make it useful in more situations (David Gibson) Cheers, Rusty. _______________________________________________ ccan mailing list ccan@lists.ozlabs.org https://lists.ozlabs.org/listinfo/ccan
