Behdad Esfahbod 2337f0d047 Internally use hb_malloc/.../hb_free instead of malloc/.../free 
Redefining those stock names as macros was conflicting with gcc 10

Fix djgpp complains by tweaking templates (#1579) 
For some reasons djgpp doesn't understand "unsigned int" can be same
with one of uint*_t anyway so lets do that for it explicitly.

Just to note, our CI's djgpp is based GCC 7.2.0 and isn't old.

Behdad Esfahbod f6fc5574d3 Add pointer magic operators to hb_atomic_ptr_t 2018-11-05 13:23:54 -05:00
Behdad Esfahbod 35d410f2ba Remove ASSERT_POD 
Newer compilers / language allows structs with constructor in union.
So, this was not actually testing anything.  Indeed, the recent
change in DISALLOW_COPY *is* making some of our types non-POD.
That broke some bots.

Just remove this since it wasn't doing much, and I'd rather have
DISALLOW_COPY.

Behdad Esfahbod 39bd07aed5 Fix bunch of unused parameter warnings 
Show up with gcc -O0.

There's a few more but those are functions that need to be filled in.

Maybe this is a lost battle...

[ubsan] Use unsigned int instead enum where needed (#1270) 
Actually the check is right,

On -myanmar.hh, on that particular switch, OT_C is indic_category_t
but OT_D is myanmar_category_t so we are mixing the types in one variable.

And on -arabic.cc, step can goes one number higher than step_t enum in the
loop so we are actually using it as an unsinged int.

Behdad Esfahbod 70136a78cb Remove F_COMBINE 
Now I wonder if any bots will be unhappy we calling | in static const initializations...
Or would that cost runtime init?  Our tests don't detect any..

Behdad Esfahbod 8c0d1916a4 Improve CGJ skipping logic 
Previously we made CGJ unskippable.  Now, if CGJ did NOT prevent
any reordering, allow skipping over it.  To make this work we
had to make changes to the Arabic mark reordering algorithm
implementation to renumber moved MCM marks.  See comments.
