62d793b939 Remove warning about parser signature being wrong 2015-12-20 11:51:01 +01:00

c95b2987b1 Support variable array length instantiation on MSVC 
As MSVC doesn't implement C99, variable-length arrays
are not supported. We use _alloca instead.

50a73f6ab2 Merge remote-tracking branch 'upstream/master' into fix-wrong_bit_length 2015-12-07 11:05:05 +01:00

ca1d8df06c don't allocate a new arena in h_bind, use the existing one 
Rationale: If memory allocation fails in the inner parse and we
longjump up the stack, the temporary arena will be missed and leak.

NB: This change means that any allocations done by the continuation
(in the form of new parsers, probably) will persist for the
lifetime of the parse result. Beware of wasting too much memory
this way! The bind continuation should generally keep dynamic
allocations to a minimum.

af73181cf4 Fix #118 
NEWS:
* Switching endianness mid-byte no longer potentially re-reads bytes.
* bit_offset now consistently refers to the number of bits already
  read.
* HParsedTokens now have a bit_length field; this is a size_t.  This
  may be removed for memory reasons.

The bit writer has not yet been updated to match; the result of
switching bit writer endianness in the middle of a byte remains
undefined.

849178d60b Ported to NetBSD (2/2): Add casts for character class detection 
NetBSD's character class test macros are defined such that they produce
a compiler warning when given a char argument. Adding a cast to the call
fixes this.

c8fc061ea6 Ditch longs and long longs in favor of stdint.h types, which has cascading 
effects throughout, including use of inttypes.h/PRI[ud]64 because printf() is
still stuck in a long world, conversion of %lu to %zu for printing values of
type size_t, and changing/renaming the g_check_cmp* family of functions.
