Behdad Esfahbod c4aa10ebc8 Use constexpr to replace passthru_ bools 2019-07-02 19:15:03 -07:00
Behdad Esfahbod 2e48fd0779 Sprinkle constexpr around
Being conservative.  Also not sure it makes any real difference
in our codebase.

Behdad Esfahbod 60653a7adb Remove HB_VECTOR_SIZE
It was cumbersome to get it to work reliably, for dubious performance
gain, mostly in the subsetter maybe...

Life is easier without.  It was disabled forever anyway.

minor, add HB_USE_INTERNAL_QSORT
The only thing I need for a working wasm in a minimum libc,
otherwise I have to provide the very same qsort inside that libc

Eli Zaretskii d5e5f37832 This makes minor changes to allow building HarfBuzz with
mingw.org's MinGW.

src/hb-algs.hh: Don't compile _BitScanForward and _BitScanReverse
for GCC >= 4.  mingw.org's MinGW doesn't have these functions.

src/hb-atomic.hh: MemoryBarrier does exist in mingw.org's MinGW,
but it is not a macro, it is an inline function.  __MINGW32_VERSION
is a macro that exists only in mingw.org's MinGW, so conditioning
on it should not affect MinGW64, where MemoryBarrier is a macro.

src/hb-uniscribe.cc: Define E_NOT_SUFFICIENT_BUFFER if it is not
defined (mingw.org's MinGW doesn't).

src/hb.hh: Don't include intrin.h for mingw.org's MinGW, since that
header is not available; instead, include windows.h.  Conditioned
on __MINGW32_VERSION to avoid affecting MinGW64.

Reapply possible bsearch overflow fix
Originally introduced in 21ede86 (#1314) but as it wasn't applied to hb_bsearch
accidentally removed while merging hb_bsearch_r to it.

Behdad Esfahbod 65392b734e [ucdn] Replace UCDN with a new UCD implementation
UCDN was ~120kb of data.  New implementatoin is 69kb in default builds,
and 49kb if built with HB_OPTIMIZE_SIZE or __OPTIMIZE_SIZE__.  The
latter automatically enabled if built with -Os or -Oz.

There's room to shave off another 10kb or 20kb.  That will follow later.

Behdad Esfahbod b7be59311f Fix msan issue
The fact that HB_AUTO_RETURN will return rvalue-references for rvalues
is very disturbing.

Even apart from that, I'm totally lost re any hb_move needs or
hb_forward'ing to functions/templates where the type is fixed by
explicitly specifying template parameters.
