Bug 560280 - Reserve typelib space for bitfield data (1.22 KB, patch)
2009-02-24 20:39 UTC, Colin Walters 		none Details | Review

Description Owen Taylor 2008-11-11 05:32:51 UTC 
We should compute bitfield positions and store them in the typelib.

FieldBlob needs to be extended for this, since it's missing the 
position of the bits within the bitfield. (Possibly an incompatible change,
some shifting around of:

  guint          readable : 1; 
  guint          writable : 1;
  guint          reserved : 6;
  guint8         bits;

seems indicated. Assuming we don't care about > 32-bit fields, 
then 5 bits are needed for 'bits' and 5 for the position.)

Computation is a little challenging because bitfields differ significantly
between differnet ABIs (and on Windows you have different bitfield handling
in the Microsoft and GCC ABIs...) Will take a bit of study.

Bug 560280 - Reserve typelib space for bitfield data

We aren't calculating this yet, but better to reserve the space now.

Also, we add in a missing 16 bit reserved block that was needed
for alignment to FieldBlob, so it stays the same size while "gaining"
16 reserved bits.
